• How can I find days between different paired rows?

  - by Anthony

  I've been racking my brain about how to do this in one query without PHP code. In a nutshell, I have a table that records email activity. For the sake of this example, here is the data: recipient_id activity date 1 delivered 2011-08-30 1 open 2011-08-31 2 delivered 2011-08-30 3 delivered 2011-08-24 3 open 2011-08-30 3 open 2011-08-31 The goal: I want to display to users a single number that tells how many recipients open their email within 24 hours. E.G. "Users that open their email within 24 hours: 13 Readers" In the case of the sample data, above, the value would be "1". (Recipient one was delivered an email and opened it the next day. Recipient 2 never opened it and recipient 3 waited 5 days.) Can anyone think of a way to express the goal in a single query? Reminder: In order to count, the person must have a 'delivered' tag and at least one 'open' tag. Each 'open' tag only counts once per recipient.

• This Week in Geek History: Gmail Goes Public, Deep Blue Wins at Chess, and the Birth of Thomas Edison

  - by Jason Fitzpatrick

  Every week we bring you a snapshot of the week in Geek History. This week we’re taking a peek at the public release of Gmail, the first time a computer won against a chess champion, and the birth of prolific inventor Thomas Edison. Gmail Goes Public It’s hard to believe that Gmail has only been around for seven years and that for the first three years of its life it was invite only. In 2007 Gmail dropped the invite only requirement (although they would hold onto the “beta” tag for another two years) and opened its doors for anyone to grab a username @gmail. For what seemed like an entire epoch in internet history Gmail had the slickest web-based email around with constant innovations and features rolling out from Gmail Labs. Only in the last year or so have major overhauls at competitors like Hotmail and Yahoo! Mail brought other services up to speed. Can’t stand reading a Week in Geek History entry without a random fact? Here you go: gmail.com was originally owned by the Garfield franchise and ran a service that delivered Garfield comics to your email inbox. No, we’re not kidding. Deep Blue Proves Itself a Chess Master Deep Blue was a super computer constructed by IBM with the sole purpose of winning chess matches. In 2011 with the all seeing eye of Google and the amazing computational abilities of engines like Wolfram Alpha we simply take powerful computers immersed in our daily lives for granted. The 1996 match against reigning world chest champion Garry Kasparov where in Deep Blue held its own, but ultimately lost, in a  4-2 match shook a lot of people up. What did it mean if something that was considered such an elegant and quintessentially human endeavor such as chess was so easy for a machine? A series of upgrades helped Deep Blue outright win a match against Kasparov in 1997 (seen in the photo above). After the win Deep Blue was retired and disassembled. Parts of Deep Blue are housed in the National Museum of History and the Computer History Museum. Birth of Thomas Edison Thomas Alva Edison was one of the most prolific inventors in history and holds an astounding 1,093 US Patents. He is responsible for outright inventing or greatly refining major innovations in the history of world culture including the phonograph, the movie camera, the carbon microphone used in nearly every telephone well into the 1980s, batteries for electric cars (a notion we’d take over a century to take seriously), voting machines, and of course his enormous contribution to electric distribution systems. Despite the role of scientist and inventor being largely unglamorous, Thomas Edison and his tumultuous relationship with fellow inventor Nikola Tesla have been fodder for everything from books, to comics, to movies, and video games. Other Notable Moments from This Week in Geek History Although we only shine the spotlight on three interesting facts a week in our Geek History column, that doesn’t mean we don’t have space to highlight a few more in passing. This week in Geek History: 1971 – Apollo 14 returns to Earth after third Lunar mission. 1974 – Birth of Robot Chicken creator Seth Green. 1986 – Death of Dune creator Frank Herbert. Goodnight Dune. 1997 – Simpsons becomes longest running animated show on television. Have an interesting bit of geek trivia to share?

• HTML Presence Controls for Communications Server 14 CodePlex Project

  Showing Presence on the Web If youre running Office Communicator Server 2007 R2, you know that your only out-of-the-box option for showing presence on the web is to use the NameControl ActiveX control that ships as part of Office.  Being an ActiveX control, this obviously means that youre limited to Internet Explorer.  Also, nobody likes ActiveX controls What if you want to show the presence of users in a pure ASP.NET or HTML application and cant assume that the user has Communicator installed you need anASP.NET or HTML presence control.  HTML Presence Controls for Microsoft Communications Server 14 We recently worked with the UC team at Microsoft on a keynote demo for TechEd 2010 in New Orleans.  The demo was for a fictitious airline Fabrikam Airlines that wanted to show the presence of customer service and reservations agents on its website.  Customers could also start an instant message conversation with the agents using a Silverlight web chat window that used WCF to communicate with the backend UCMA application. We built HTML Presence Controls that use AJAX to poll a REST-based WCF service running in IIS and hosting a UCMA 3.0 presence subscription application.   Microsoft has graciously allowed us to publish these on CodePlex so that the development community can benefit from them:  http://htmlpresencecontrols.codeplex.com/ We will be maintaining the CodePlex project as new builds of UCMA 3.0 become available.  Check out the project home page on CodePlex for some more in-depth details on how the controls are implemented. ASP.NET Server Control Implementation Were providing an ASP.NET Server Control implementation that you can use stand-alone or in a GridView or Repeater (or other layout control).  The control has properties that allow you to control its appearance, e.g. you can choose whether or not to show the contacts name or availability text. You can also use the server control in a layout control such as a GridView by putting it in a TemplateColumn and binding to the Sip Uri in the data source. Disclaimer Once we started working on these, we realized why Microsoft hasnt shipped such controls as part of the product.  There are some tradeoffs you have to be aware of when using these controls, heres the high level. Privacy The backend UCMA 3.0 application that subscribes to presence of contacts runs as a trusted application and can thus retrieve the presence of any user in the organization.  Theres currently no good way in UCMA to apply any privacy rules to ensure that the consumer of the presence controls has permission to see the presence of the contacts that the controls are bound to.  Just to be absolutely crystal clear These controls provide a way to query the presence of any user in the organization, regardless of the privacy relationship between the person consuming the controls and the contacts whose presence is being displayed. Were exploring options for a design pattern that would allow you to inject some privacy controls.  Keep in mind though that you would most likely be responsible for implementing this logic, as there is currently no functionality in UCMA that allows you to do that. Polling the WCF REST Service The controls poll the backend WCF service to retrieve the presence of contacts - you can control the refresh interval so that they poll less often. We implemented a caching layer so that the WCF service is always communicating with a presence cache it never communicates directly with Communications Server.  For example, if your web page is showing the presence of sip:[email protected] and 500 people have the page open, the presence cache only contains one instance of the subscription Communications Server is not being polled 500 times for the presence of that contact. Once the presence of a contact changes, it is updated in the cache.  There are some server-based push mechanisms that would work nicely here, such as the one that Outlook Web Access 2010 uses.  Unfortunately we didnt have time to explore these options. Community Contribution Take a look at the project Issue Tracker, there are a couple of things we can use some help with.  Shoot me a note if youre interested in contributing to the project. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Meet Thomas, the Most Innovational person in Oracle Direct EMEA of Q1

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Thomas was voted, by his peers,  the most Innovational person in Oracle Direct EMEA of Q1, the first quarter of this fiscal! Thomas, a Business Development Consultant at Oracle Direct’s Applications Team, taught himself how to use and leverage the power of social engagement consistent with Oracle’s Social Media Policy.  From these learning's he provided both his and other applications teams in Dublin with huge amounts of training and has presented his findings to the teams on more than one occasion. It is important to recognise that this isn't just a great idea....it actually works! The results speak for themselves. Thomas is engaging with customers and prospects via their preferred channel of communication and creating a strong personal social brand. We congratulate Thomas for his efforts of raising Social Media to the next level within Business Development Group. He put a lot of work into Social Selling, as one of the first within the BDG and set the example for a new innovative approach on how to sell anno 2013. He deserves to be recognized for this. His contribution to social media has been a great inspiration for all Business Development Consultants or Business Relationship Consultants. He knows what he talks about and has great conversion rates out of his social media campaigns. And he doesn't mind sharing his knowledge with everybody. Great effort in searching for new ways of communication and social selling. Thomas has shown great initiative towards leveraging the social media and networks (twitter, linkedin) to find new business opportunities in a previously way. He has shown great out-of-the-box thinking while addressing new companies and prospects and has shared those experiences and ideas to help his colleagues use the same approach. This included a presentation, informational emails and a general helpful attitude from him. He also shared his success stories from his innovational approach.  Thomas is showing initiative with an innovative and fresh character, truly helping people to try something new  with a focus on selling across channels and working for the CRM team which is focused on selling social. We think the way Thomas positions social, by using social is innovative and inspirational. What better way to tell your clients do social, by engaging with them on a social platform? Going always the extra mile, we believe, that Thomas Brits, is an innovator from the day he walked into Oracle Direct. The way Thomas operates on the work floor by introducing new ideas to find the best opportunities as possible shows he runs the extra mile for coming up with new ideas around how to engage with customers more efficiently for instance via Social Media. Thomas also organises power hours/days for the team. He is the best! /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-ascii- mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi- mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• Welcome 2011

  - by WeigeltRo

  Things that happened in 2010 MIX10 was absolutely fantastic. Read my report of MIX10 to see why.   The dotnet Cologne 2010, the community conference organized by the .NET user group Köln and my own group Bonn-to-Code.Net became an even bigger success than I dared to dream of.   There was a huge discrepancy between the efforts by Microsoft to support .NET user groups to organize public live streaming events of the PDC keynote (the dotnet Cologne team joined forces with netug  Niederrhein to organize the PDCologne) and the actual content of the keynote. The reaction of the audience at our event was “meh” and even worse I seriously doubt we’ll ever get that number of people to such an event (which on top of that suffered from technical difficulties beyond our control).   What definitely would have deserved the public live streaming event treatment was the Silverlight Firestarter (aka “Silverlight Damage Control”) event. And maybe we would have thought about organizing something if it weren’t for the “burned earth” left by the PDC keynote. Anyway, the stuff shown at the firestarter keynote was the topic of conversations among colleagues days later (“did you see that? oh yeah, that was seriously cool”). Things that I have learned/observed/noticed in 2010 In the long run, there’s a huge difference between “It works pretty well” and “it just works and I never have to think about it”. I had to get rid of my USB graphics adapter powering the third monitor (read about it in this blog post). Various small issues (desktop icons sometimes moving their positions after a reboot for no apparent reasons, at least one game I couldn’t get run at all, all three monitors sometimes simply refusing to wake up after standby) finally made me buy a PCIe 1x graphics adapter. If you’re interested: The combination of a NVIDIA GTX 460 and a GT 220 is running in “don’t make me think” mode for a couple of months now.   PowerPoint 2010 is a seriously cool piece of software. Not only the new hardware-accelerated effects, but also features like built-in background removal and picture processing (which in many cases are simply “good enough” and save a lot of time) or the smart guides.   Outlook 2010 crashes on me a lot. I haven’t been successful in reproducing these crashes, they just happen when every couple of days on different occasions (only thing in common: I clicked something in the main window – yeah, very helpful observation)   Visual Studio 2010 reminds me of Visual Studio 2005 before SP1, which is actually not a good thing to say about a piece of software. I think it’s telling that Microsoft’s message regarding the beta of SP1 has been different from earlier service pack betas (promising an upgrade path for a beta to the RTM sounds to me like “please, please use it NOW!”).   I have a love/hate relationship with ReSharper. I don’t want to develop without it, but at the same time I can’t fail to notice that ReSharper is taking a heavy toll in terms of performance and sometimes stability. Things I’m looking forward to in 2011 Obviously, the dotnet Cologne 2011. We already have been able to score some big name sponsors (Microsoft, Intel), but we’re still looking for more sponsors. And be assured that we’ll make sure that our partners get the most out of their contribution, regardless of how big or small.   MIX11, period.    Silverlight 5 is going to be great. The only thing I’m a bit nervous about is that I still haven’t read anything official on whether C# next version’s async/await will be in it. Leaving that out would be really stupid considering the end-of-2011 release of SL5 (moving the next release way into the future).

• Multidimensional Thinking–24 Hours of Pass: Celebrating Women in Technology

  - by smisner

  It’s Day 1 of #24HOP and it’s been great to participate in this event with so many women from all over the world in one long training-fest. The SQL community has been abuzz on Twitter with running commentary which is fun to watch while listening to the current speaker. If you missed the fun today because you’re busy with all that work you’ve got to do – don’t despair. All sessions are recorded and will be available soon. Keep an eye on the 24 Hours of Pass page for details. And the fun’s not over today. Rather than run 24 hours consecutively, #24HOP is now broken down into 12-hours over two days, so check out the schedule to see if there’s a session that interests you and fits your schedule. I’m pleased to announce that my business colleague Erika Bakse ( Blog | Twitter) will be presenting on Day 2 – her debut presentation for a PASS event. (And I’m also pleased to say she’s my daughter!) Multidimensional Thinking: The Presentation My contribution to this lineup of terrific speakers was Multidimensional Thinking. Here’s the abstract: “Whether you’re developing Analysis Services cubes or creating PowerPivot workbooks, you need to get into a multidimensional frame of mind to produce a model that best enables users to answer their business questions on their own. Many database professionals struggle initially with multidimensional models because the data modeling process is much different than the one they use to produce traditional, third normal form databases. In this session, I’ll introduce you to the terminology of multidimensional modeling and step through the process of translating business requirements into a viable model.” If you watched the presentation and want a copy of the slides, you can download a copy here. And you’re welcome to download the slides even if you didn’t watch the presentation, but they’ll make more sense if you did! Kimball All the Way There’s only so much I can cover in the time allotted, but I hope that I succeeded in my attempt to build a foundation that prepares you for starting out in business intelligence. One of my favorite resources that will get into much more detail about all kinds of scenarios (well beyond the basics!) is The Data Warehouse Toolkit (Second Edition) by Ralph Kimball. Anything from Kimball or the Kimball Group is worth reading. Kimball material might take reading and re-reading a few times before it makes sense. From my own experience, I found that I actually had to just build my first data warehouse using dimensional modeling on faith that I was going the right direction because it just didn’t click with me initially. I’ve had years of practice since then and I can say it does get easier with practice. The most important thing, in my opinion, is that you simply must prototype a lot and solicit user feedback, because ultimately the model needs to make sense to them. They will definitely make sure you get it right! Schema Generation One question came up after the presentation about whether we use SQL Server Management Studio or Business Intelligence Development Studio (BIDS) to build the tables for the dimensional model. My answer? It really doesn’t matter how you create the tables. Use whatever method that you’re comfortable with. But just so happens that it IS possible to set up your design in BIDS as part of an Analysis Services project and to have BIDS generate the relational schema for you. I did a Webcast last year called Building a Data Mart with Integration Services that demonstrated how to do this. Yes, the subject was Integration Services, but as part of that presentation, I showed how to leverage Analysis Services to build the tables, and then I showed how to use Integration Services to load those tables. I blogged about this presentation in September 2010 and included downloads of the project that I used. In the blog post, I explained that I missed a step in the demonstration. Oops. Just as an FYI, there were two more Webcasts to finish the story begun with the data – Accelerating Answers with Analysis Services and Delivering Information with Reporting Services. If you want to just cut to the chase and learn how to use Analysis Services to build the tables, you can see the Using the Schema Generation Wizard topic in Books Online.

• Some Original Expressions

  - by Phil Factor

  Guest Editorial for Simple-Talk newsletterIn a guest editorial for the Simple-Talk Newsletter, Phil Factor wonders if we are still likely to find some more novel and unexpected ways of using the newer features of Transact SQL: or maybe in some features that have always been there! There can be a great deal of fun to be had in trying out recent features of SQL Expressions to see if  they provide new functionality.  It is surprisingly rare to find things that couldn’t be done before, but in a different   and more cumbersome way; but it is great to experiment or to read of someone else making that discovery.  One such recent feature is the ‘table value constructor’, or ‘VALUES constructor’, that managed to get into SQL Server 2008 from Standard SQL.  This allows you to create derived tables of up to 1000 rows neatly within select statements that consist of  lists of row values.  E.g. SELECT Old_Welsh, number FROM (VALUES ('Un',1),('Dou',2),('Tri',3),('Petuar',4),('Pimp',5),('Chwech',6),('Seith',7),('Wyth',8),('Nau',9),('Dec',10)) AS WelshWordsToTen (Old_Welsh, number) These values can be expressions that return single values, including, surprisingly, subqueries. You can use this device to create views, or in the USING clause of a MERGE statement. Joe Celko covered  this here and here.  It can become extraordinarily handy to use once one gets into the way of thinking in these terms, and I’ve rewritten a lot of routines to use the constructor, but the old way of using UNION can be used the same way, but is a little slower and more long-winded. The use of scalar SQL subqueries as an expression in a VALUES constructor, and then applied to a MERGE, has got me thinking. It looks very clever, but what use could one put it to? I haven’t seen anything yet that couldn’t be done almost as  simply in SQL Server 2000, but I’m hopeful that someone will come up with a way of solving a tricky problem, just in the same way that a freak of the XML syntax forever made the in-line  production of delimited lists from an expression easy, or that a weird XML pirouette could do an elegant  pivot-table rotation. It is in this sort of experimentation where the community of users can make a real contribution. The dissemination of techniques such as the Number, or Tally table, or the unconventional ways that the UPDATE statement can be used, has been rapid due to articles and blogs. However, there is plenty to be done to explore some of the less obvious features of Transact SQL. Even some of the features introduced into SQL Server 2000 are hardly well-known. Certain operations on data are still awkward to perform in Transact SQL, but we mustn’t, I think, be too ready to state that certain things can only be done in the application layer, or using a CLR routine. With the vast array of features in the product, and with the tools that surround it, I feel that there is generally a way of getting tricky things done. Or should we just stick to our lasts and push anything difficult out into procedural code? I’d love to know your views.

• Do MORE with WebCenter - Webcast Overview & TIES Tour

  - by Michael Snow

  Today's post is from Michelle Huff, Senior Director, Product Management, Oracle WebCenter `````````````````  In case you missed it, I presented on a webcast yesterday focused on how you can “Do More with Oracle WebCenter – Expand Beyond Content Management.” As you may remember, we rebranded Oracle’s Enterprise Content Management (ECM) Suite, which some people knew by the wonderfully techie three-letter acronyms -- UCM, URM & IPM -- to Oracle WebCenter Content last year. Since it’s a unified ECM platform, I’ve seen many customers over the years continue to expand the number of content-centric solutions and application integrations powered by WebCenter throughout their organizations. But, did you know WebCenter also provides portal, collaboration and web experience management capabilities as well? This enables you to leverage your existing investment in the WebCenter platform as well as the information you’re managing to create engaging sites, collaborative spaces, or self-service portals and composite applications. In the webcast I walked through six different ways that you can do more with WebCenter: Collaborative content contribution and sharing environment Share content across intranets and extranets Combine content in composite applications Create targeted online experiences Manage interactive social experiences Optimize multi-channel customer experiences Joining me on the call was Greg Utecht with TIES. TIES is a joint powers cooperative owned by 46 Minnesota school districts, represents 514 schools – and provides software applications, hardware and software, internet service and professional development designed by educators for education. I was having a lot of fun over the past few days talking with Greg about the TIES implementation and future plans with WebCenter. He joined me on the call for a little Q&A to explain how he’s using WebCenter today for their iContent implementation for document management, records management and archiving. And also covered how they have expanded their implementation to create a collaborative space called their HRPay System with WebCenter to facilitate collaboration and to better engage their users within the school districts. During our conversation a few questions came from the audience about their implementation. They were curious to see how the system looked – so let’s take a peak. This first screenshot shows the screen that a human resources or payroll worker in one of our member districts would see upon logging in, based on their credentials and role in their district. This shows the result of clicking on the SUBSCRIBE link on the main page. It allows the user to subscribe to parts of the portal which will e-mail him/her when those are updated in any way. This shows the screen that a human resources or payroll worker in one of our member districts would see upon clicking on the Resources link. This shows the screen that a human resources or payroll worker in one of our member districts would see upon clicking on the Finance Advisory link. It shows the discussion threads and document sharing areas. This shows the screen that appears when the forum topic on the preceding screen is clicked. This shows the screen portlet up close with shared documents. This shows the screen that appears when a shared document is clicked on. Note that there is also a download button and an update button, meaning people can work on these collaboratively. If you missed the webcast, check it out! You can watch the replay OnDemand HERE. If you attended the webcast, thanks for joining - I hoped you learned a little from the session. I learned that kids are getting digital report cards today! Wow, have times changed with technology. Uh oh, is this when I start saying “You know, back in my days…?”

• SQL Server Date Comparison Functions

  - by HighAltitudeCoder

  A few months ago, I found myself working with a repetitive cursor that looped until the data had been manipulated enough times that it was finally correct.  The cursor was heavily dependent upon dates, every time requiring the earlier of two (or several) dates in one stored procedure, while requiring the later of two dates in another stored procedure. In short what I needed was a function that would allow me to perform the following evaluation: WHERE MAX(Date1, Date2) < @SomeDate The problem is, the MAX() function in SQL Server does not perform this functionality.  So, I set out to put these functions together.  They are titled: EarlierOf() and LaterOf(). /**********************************************************                               EarlierOf.sql   **********************************************************/ /**********************************************************   Return the later of two DATETIME variables.   Parameter 1: DATETIME1 Parameter 2: DATETIME2   Works for a variety of DATETIME or NULL values. Even though comparisons with NULL are actually indeterminate, we know conceptually that NULL is not earlier or later than any other date provided.   SYNTAX: SELECT dbo.EarlierOf('1/1/2000','12/1/2009') SELECT dbo.EarlierOf('2009-12-01 00:00:00.000','2009-12-01 00:00:00.521') SELECT dbo.EarlierOf('11/15/2000',NULL) SELECT dbo.EarlierOf(NULL,'1/15/2004') SELECT dbo.EarlierOf(NULL,NULL)   **********************************************************/ USE AdventureWorks GO   IF EXISTS       (SELECT *       FROM sysobjects       WHERE name = 'EarlierOf'       AND xtype = 'FN'       ) BEGIN             DROP FUNCTION EarlierOf END GO   CREATE FUNCTION EarlierOf (       @Date1                              DATETIME,       @Date2                              DATETIME )   RETURNS DATETIME   AS BEGIN       DECLARE @ReturnDate     DATETIME         IF (@Date1 IS NULL AND @Date2 IS NULL)       BEGIN             SET @ReturnDate = NULL             GOTO EndOfFunction       END         ELSE IF (@Date1 IS NULL AND @Date2 IS NOT NULL)       BEGIN             SET @ReturnDate = @Date2             GOTO EndOfFunction       END         ELSE IF (@Date1 IS NOT NULL AND @Date2 IS NULL)       BEGIN             SET @ReturnDate = @Date1             GOTO EndOfFunction       END         ELSE       BEGIN             SET @ReturnDate = @Date1             IF @Date2 < @Date1                   SET @ReturnDate = @Date2             GOTO EndOfFunction       END         EndOfFunction:       RETURN @ReturnDate   END -- End Function GO   ---- Set Permissions --GRANT SELECT ON EarlierOf TO UserRole1 --GRANT SELECT ON EarlierOf TO UserRole2 --GO                                                                                             The inverse of this function is only slightly different. /**********************************************************                               LaterOf.sql   **********************************************************/ /**********************************************************   Return the later of two DATETIME variables.   Parameter 1: DATETIME1 Parameter 2: DATETIME2   Works for a variety of DATETIME or NULL values. Even though comparisons with NULL are actually indeterminate, we know conceptually that NULL is not earlier or later than any other date provided.   SYNTAX: SELECT dbo.LaterOf('1/1/2000','12/1/2009') SELECT dbo.LaterOf('2009-12-01 00:00:00.000','2009-12-01 00:00:00.521') SELECT dbo.LaterOf('11/15/2000',NULL) SELECT dbo.LaterOf(NULL,'1/15/2004') SELECT dbo.LaterOf(NULL,NULL)   **********************************************************/ USE AdventureWorks GO   IF EXISTS       (SELECT *       FROM sysobjects       WHERE name = 'LaterOf'       AND xtype = 'FN'       ) BEGIN             DROP FUNCTION LaterOf END GO   CREATE FUNCTION LaterOf (       @Date1                              DATETIME,       @Date2                              DATETIME )   RETURNS DATETIME   AS BEGIN       DECLARE @ReturnDate     DATETIME         IF (@Date1 IS NULL AND @Date2 IS NULL)       BEGIN             SET @ReturnDate = NULL             GOTO EndOfFunction       END         ELSE IF (@Date1 IS NULL AND @Date2 IS NOT NULL)       BEGIN             SET @ReturnDate = @Date2             GOTO EndOfFunction       END         ELSE IF (@Date1 IS NOT NULL AND @Date2 IS NULL)       BEGIN             SET @ReturnDate = @Date1             GOTO EndOfFunction       END         ELSE       BEGIN             SET @ReturnDate = @Date1             IF @Date2 > @Date1                   SET @ReturnDate = @Date2             GOTO EndOfFunction       END         EndOfFunction:       RETURN @ReturnDate   END -- End Function GO   ---- Set Permissions --GRANT SELECT ON LaterOf TO UserRole1 --GRANT SELECT ON LaterOf TO UserRole2 --GO                                                                                             The interesting thing about this function is its simplicity and the built-in NULL handling functionality.  Its interesting, because it seems like something should already exist in SQL Server that does this.  From a different vantage point, if you create this functionality and it is easy to use (ideally, intuitively self-explanatory), you have made a successful contribution. Interesting is good.  Self-explanatory, or intuitive is FAR better.  Happy coding! Graeme

• Customer Loyalty vs. Customer Engagement: Who Cares?

  - by Jeb Dasteel-Oracle

  Have you read the recent Forbes OracleVoice blog titled Customer Loyalty is Dead. Long Live Engagement!? If you haven’t, take a look. This article prompted lots of conversation in the social realm. Many who read the article voiced their reactions to the headline and now I’m jumping in to add my view. Normal 0 false false false EN-US X-NONE X-NONE Customer loyalty is still key. It’s the effect and engagement is the cause. We at least know that to be true for our customers. We are in an age where customers are demanding to be heard. We need them to be actively involved – or engaged – as well. Greater levels of customer engagement, properly targeted, positively correlate with satisfaction. Our data has shown us this over and over. Satisfied customers are more loyal and more willing to vocalize their satisfaction through referencing, and are more likely to purchase again, all of which in turn drives incremental revenue – from the customer doing the referencing AND the customer on the receiving end of that reference. Turning this around completely, if we begin to see the level of a customer’s engagement start to wane, this is an indicator that their satisfaction, loyalty, and future revenue are likely at risk. At Oracle, we’ve put in place many programs to target, encourage, and then track engagement, allowing us to measure engagement as a determinant of loyalty. Some of these programs include our Key Accounts, solution design and architectural, Executive Sponsorship, as well as executive advisory boards. Specific programs allow us to engage specific contacts within specific customer organizations (based on role) and then systematically track their engagement activities over time, along side of tracking customer satisfaction, loyalty, referenceability, and incremental revenue contribution. Continuous measurement of engagement allows us to better understand customer views of what it means to partner with a provider and adjust program participation to better meet the needs of the partnership. We can also track across customer segments, and design new programs that are even more effective than the ones we have in place today.

• How do you think while formulating Sql Queries. Is it an experience or a concept ?

  - by Shantanu Gupta

  I have been working on sql server and front end coding and have usually faced problem formulating queries. I do understand most of the concepts of sql that are needed in formulating queries but whenever some new functionality comes into the picture that can be dont using sql query, i do usually fails resolving them. I am very comfortable with select queries using joins and all such things but when it comes to DML operation i usually fails For every query that i never done before I usually finds uncomfortable with that while creating them. Whenever I goes for an interview I usually faces this problem. Is it their some concept behind approaching on formulating sql queries. Eg. I need to create an sql query such that A table contain single column having duplicate record. I need to remove duplicate records. I know i can find the solution to this query very easily on Googling, but I want to know how everyone comes to the desired result. Is it something like Practice Makes Man Perfect i.e. once you did it, next time you will be able to formulate or their is some logic or concept behind. I could have get my answer of solving above problem simply by posting it on stackoverflow and i would have been with an answer within 5 to 10 minutes but I want to know the reason. How do you work on any new kind of query. Is it a major contribution of experience or some an implementation of concepts. Whenever I learns some new thing in coding section I tries to utilize it wherever I can use it. But here scenario seems to be changed because might be i am lagging in some concepts.

• Quality assurance in small developer teams

  - by Kim L

  Ideally, in a project you will developers, testers, QA manager(s) etc which all make their contribution to the quality of the code. But what if you don't have that kind of resources? If you just have, for example, three developers and don't have the resources to hire a full time QA manager, how do you assure that the code quality meets set standards? What kind of things do you pay attention to in quality assurance? Quality isn't just about the code doing what it is supposed to do (code is properly tested with automatic tests). Quality is also about the code being clean (readable, maintainable, well structured, documented, etc). I'm looking forward to hear what kind of processes you have applied to your team to assure that the quality meets the set standards. We've applied a process where we rotate the QA role between the developers. Each developer is responsible for QA one week at a time. Each changeset is revised and checked that existing tests pass, required new tests have been written, that the code is clean and, of course, that the project builds.

• Adding a Taxonomy Filter to a Custom Post Type

  - by ken

  There is an amazing conversation from about two years ago on the Wordpress Answer site where a number of people came up with good solutions for adding a taxonomy filter to the admin screen for your custom post types (see URL for screen I'm referring to): http://[yoursite.com]/wp-admin/edit.php?s&post_status=all&post_type=[post-type] Anyway, I loved Michael's awesome contribution but in the end used Somatic's implementation with the hierarchy option from Manny. I wrapped it in a class - cuz that's how I like to do things -- and it ALMOST works. The dropdown appears but the values in the dropdown are all looking in the $_GET property for the taxonomies slug-name that you are filtering by. For some reason I don't get anything. I looked at the HTML of the dropdown and it appears ok to me. Here's a quick screen shot for some context: You can tell from this that my post-type is called "exercise" and that the Taxonomy I'm trying to use as a filter is "actions". Here then is the HTML surrounding the dropdown list: <select name="actions" id="actions" class="postform"> <option value="">Show all Actions</option> <option value="ate-dinner">Ate dinner(1)</option> <option value="went-running">Went running(1)</option> </select> I have also confirmed that all of the form elements are within the part of the DOM. And yet if I choose "Went running" and click on the filter button the URL query string comes back without ANY reference to what i've picked. More explicitly, the page first loads with the following URL: /wp-admin/edit.php?post_type=exercise and after pressing the filter button while having picked "Went Running" as an option from the actions filter: /wp-admin/edit.php?s&post_status=all&post_type=exercise&action=-1&m=0&actions&paged=1&mode=list&action2=-1 actually you can see a reference to an "actions" variable but it's set to nothing and as I now look in detail it appears that the moment I hit "filter" on the page it resets the filter dropdown to the default "Show All Actions". Can anyone help me with this?

• How to handle management trying to interfere with the project (including architecture decision)

  - by Zwei Steinen

  I feel this is not a very good question to post on SO, but I need some advice from experienced developers... (I'm a second year developer) I guess this is a problem to many, many projects, but in our case, it is getting intense. There were so much interference from people that don't know a bit about software development, that our development came to an almost complete stop. We had to literary escape to another location to get any useful job done. Now we were happily producing results, but then I get a request for a "meeting" and it's them again. I have a friendly relationship with them, but I feel very daunted at the thought of talking about non-sense all over again. Should I be firm and tell them to shut up and wait for our results? Or should I be diplomatic and create an illusion they are making a positive contribution or something?? My current urge is to be unfriendly and murmur some stuff so they will give up or something. What would you do if you were in this situation?

• can a webservice load jars during run time

  - by KItis

  I have created a simple web-service using Java. i want to load jars related to web-service during runtime. I have done this task for normal Java application. there what I did was JarFile jar = new JarFile(f.getPath()); final Manifest manifest = jar.getManifest(); final Attributes mattr = manifest.getMainAttributes(); // Read the manifset in jar files and get the Name attribute // whare it specified the class that need to load //for (Object a : mattr.keySet()) { for (Iterator iter = mattr.keySet().iterator(); iter.hasNext();) { Object obj = (Object)iter.next(); if ("ServiceName".equals(obj.toString())) className = mattr.getValue((Name) obj); //System.out.println(className); } /* * Create the jar class loader and use the first argument passed * in from the command line as the jar file to use. */ JarClassLoader jarLoader = new JarClassLoader(f.getPath()); /* Load the class from the jar file and resolve it. */ Class c = jarLoader.loadClass(className, true); My problem is can I put jars that need to be loaded during run time in to separate folder rather than putting in to WEBINF folder. do i have to put jars both in axis and web-application. thanks in advance for any contribution for this question.

• Jquery resizing image

  I'd like to start a discussion about the image resizing using jQuery. That's my contribution: But I think I'm far away from the solution. What about the cropping? Who can help me? $(document).ready(function() { $('.story-small img').each(function() { var maxWidth = 100; // Max width for the image var maxHeight = 100; // Max height for the image var ratio = 0; // Used for aspect ratio var width = $(this).width(); // Current image width var height = $(this).height(); // Current image height // Check if the current width is larger than the max if(width > maxWidth){ ratio = maxWidth / width; // get ratio for scaling image $(this).css("width", maxWidth); // Set new width $(this).css("height", height * ratio); // Scale height based on ratio height = height * ratio; // Reset height to match scaled image } // Check if current height is larger than max if(height > maxHeight){ ratio = maxHeight / height; // get ratio for scaling image $(this).css("height", maxHeight); // Set new height $(this).css("width", width * ratio); // Scale width based on ratio width = width * ratio; // Reset width to match scaled image } }); });

• To use the 'I' prefix for interfaces or not to

  - by ng

  That is the question? So how big a sin is it not to use this convention when developing a c# project? This convention is widely used in the .NET class library. However, I am not a fan to say the least, not just for asthetic reasons but I don't think it makes any contribution. For example is IPSec an interface of PSec? Is IIOPConnection An interface of IOPConnection, I usually go to the definition to find out anyway. So would not using this convention cause confusion? Are there any c# projects or libraries of note that drop this convention? Do any c# projects that mix conventions, as unfortunately Apache Wicket does? The Java class libraries have existed without this for many years, I don't feel I have ever struggled to read code without it. Also, should the interface not be the most primitive description? I mean IList<T> as an interface for List<T> in c#, is it not better to have List<T> and LinkedList<T> or ArrayList<T> or even CopyOnWriteArrayList<T>? The classes describe the implementation? I think I get more information here, than I do from List<T> in c#.

• Tell bots apart from human visitors for stats?

  - by Pekka

  I am looking to roll my own simple web stats script. The only major obstacle on the road, as far as I can see, is telling human visitors apart from bots. I would like to have a solution for that which I don't need to maintain on a regular basis (i.e. I don't want to update text files with bot-related User-agents). Is there any open service that does that, like Akismet does for spam? Or is there a PHP project that is dedicated to recognizing spiders and bots and provides frequent updates? To clarify: I'm not looking to block bots. I do not need 100% watertight results. I just want to exclude as many as I can from my stats. In know that parsing the user-Agent is an option but maintaining the patterns to parse for is a lot of work. My question is whether there is any project or service that does that already. Bounty: I thought I'd push this as a reference question on the topic. The best / most original / most technically viable contribution will receive the bounty amount.

• SQL SERVER – Mirroring Configured Without Domain – The server network address TCP://SQLServerName:50

  Regular readers of my blog will be aware of my friend who called me few days ago with very a funny SQL Problem SQL SERVER – SSMS Query Command(s) completed successfully without ANY Results. This time, it did not take long before he called me up with another interesting problem, although the issue he was facing this time was not that interesting and also very specific to him, however, he insisted me to share with all of you. Let us understand his situation at first. My friend is preparing for DBA exam Exam 70-450: PRO: Designing, Optimizing and Maintaining a Database Server Infrastructure using Microsoft SQL Server 2008 and for the same, he was trying to set up replication on his local laptop. He had installed two different instances of SQL Server on his computer and every time when he started the mirroring, it failed with common error message. The server network address “TCP://SQLServer:5023? cannot be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. (Microsoft SQL Server, Error: 1418) Well, before he contacted me, he searched online and checked my article written on the error in mirroring. However, he tried all the four suggestions, but it did not solve his problem. He called me at a reasonable time of late evening (unlike last time, which was midnight!). I even tried all the seven different suggestions myself, as previously proposed in my article; however, none of them worked. While looking at closely at services, I noticed something very simple. He was running all the instances on ‘Network Services’. In fact, his computer was a stand-alone computer. There was no network at all. Also, there was no domain or any other advance network concepts implemented. I just changed services from ‘Network Services’ to ‘Local System’ as his SQL Server was running on his local system and there were no network services. This prompted to restart the services. As this was not the production server and his development machine, we restarted the services on the laptop (do not restart services on production server without proper planning). After changing the ‘services log on’ account to localsystem, when he attempted to reconfigure the mirroring it worked right away. As usually in production server, proper domains are configured and advance network concepts are implemented I had never faced this type of problem earlier. My friend insisted to post this solution to his situation, wherein there was no domain configured and setting up mirroring was throwing an error. According to him, this is bound to help people, like him, who are preparing for certification using single system.

• Display System Information on Your Desktop with Desktop Info

  - by Asian Angel

  Do you like to monitor your system but do not want a complicated app to do it with? If you love simplicity and easy configuration then join us as we look at Desktop Info. Desktop Info in Action Desktop Info comes in a zip file format so you will need to unzip the app, place it into an appropriate “Program Files Folder”, and create a shortcut. Do NOT delete the “Read Me File”…this will be extremely useful to you when you make changes to the “Configuration File”. Once you have everything set up you are ready to start Desktop Info up. This is the default layout and set of listings displayed when you start Desktop Info up for the first time. The font colors will be a mix of colors as seen here and the font size will perhaps be a bit small but those are very easy to change if desired. You can access the “Context Menu” directly over the “information area”…so no need to look for it in the “System Tray”. Notice that you can easily access that important “Read Me File” from here… The full contents of the configuration file (.ini file) are displayed here so that you can see exactly what kind of information can be displayed using the default listings. The first section is “Options”…you will most likely want to increase the font size while you are here. Then “Items”… If you are unhappy with any of the font colors in the “information area” this is where you can make the changes. You can turn information display items on or off here. And finally “Files, Registry, & Event Logs”. Here is our displayed information after a few tweaks in the configuration file. Very nice. Conclusion If you have been looking for a system information app that is simple and easy to set up then you should definitely give Desktop Info a try.
