  • I can't believe I fell for this

    - by James Luetkehoelter
    Given the site, and the date, I should have realized that it was a joke. But I literally just spent the last 15 minutes preparing to lambaste the poster until I looked at all of the comments (I didn't want to repeat was someone said). I am such a dope.. http://thedailywtf.com/Articles/Announcing-APDB-The-Worlds-Fastest-Database.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!...(read more)

  • T-SQL Tuesday #005: On Technical Reporting

    - by Adam Machanic
    Reports. They're supposed to look nice. They're supposed to be a method by which people can get vital information into their heads. And that's obvious, right? So obvious that you're undoubtedly getting ready to close this tab and go find something better to do with your life. "Why is Adam wasting my time with this garbage?" Because apparently, it's not obvious. In the world of reporting we have a number of different types of reports: business reports, status reports, analytical reports, dashboards,...(read more)

  • Windows Phone 7 Developer Tools - January 2011 Update

    - by Nikita Polyakov
    Long time no talk? So to make up for it, here is something very new – update to WP7 Dev Tools! The Windows Phone 7 Developer Tools January 2011 Update provides bits that you would install on TOP of the current WP7 Dev tools on your machine. If you are just installing the tools for the first time, this update replaces previously released October patch. In fact, it is no longer available as this January 2011 update replaces the patch entirely. What is in this update? TextBox support for Copy&Paste Updated Emulator Image that contains Copy&Paste for your testing There have been performance tweaks for the OS Minor Bugs and Fixes How does it Work? The Copy&Paste extends a existing TextBox control to have this new functionality, There is no current API access to the Clipboard or support for other controls that are not based on TextBox. If I have/Do I need to: A current application in the marketplace/No action is required Have an application that contains a TextBox in a Pivot or Panorama control surface/Text your application in provided emulator Recommendation is to move TextBox controls from directly top of controls that listen to Gesture movement to their own pop-off screens or entire pages as this might interfear with select behavior for Copy&Paste Have controls that do no inherit from TextBox/Such controls will not get new Copy&Paste behavior Note: The update materials, FAQ and Q&A do not answer WHEN the update for the OS will be sent to the phones.  Also to note - this update does NOT update your developer phone to enable Copy&Paste or any other features. Windows Phone 7 Training Kit February Update Windows Phone Training Kit has also been updated – you can grab a fresh copy here.   Where to I find more good information, documentation and training? This very awesome blog post from the Windows Phone Developer Blog - Windows Phone 7 Documentation Landscape. Official Blog Post on the Update is here. Happy coding! -Nikita   PS: I am well aware that it is Feb 4th and not January :) If you were disappointed at CES that Microsoft said nothing at all about future of WP7, don’t forget that MWC 2011 is Feb 14th – I am going to be listening for Windows Phone announcements then, as that is where the announcements were made about Windows Phone 7.

  • SQL Trace challenge: a simple requirement

    - by Linchi Shea
    SQL Trace (or SQL Profiler) is no doubt an excellent tool. But its filtering capability is rather primitive, and is very poorly documented. Here is a request that is simple and seems to be rather reasonable. Create a trace to filter for the following: 1. All the update/delete statements, and 2. All the select/insert statements whose CPU column value is greater than 1000 or whose Duration value is greater than 1000 Now, I'm having a tough time creating a trace to meet this simple requirement. Perhaps,...(read more)

  • Better documentation for tasks waiting on resources

    - by SQLOS Team
    The sys.dm_os_waiting_tasks DMV contains a wealth of useful information about tasks waiting on a resource, but until now detailed information about the resource being consumed - sys.dm_os_waiting_tasks.resource_description - hasn't been documented, apart from a rather self-evident "Description of the resource that is being consumed."   Thanks to a recent Connect suggestion this column will get more information added. Here is a summary of the possible values that can appear in this column - Note this information is current for SQL Server 2008 R2 and Denali:   Thread-pool resource owner:•       threadpool id=scheduler<hex-address> Parallel query resource owner:•       exchangeEvent id={Port|Pipe}<hex-address> WaitType=<exchange-wait-type> nodeId=<exchange-node-id> Exchange-wait-type can be one of the following.•       e_waitNone•       e_waitPipeNewRow•       e_waitPipeGetRow•       e_waitSynchronizeConsumerOpen•       e_waitPortOpen•       e_waitPortClose•       e_waitRange Lock resource owner:<type-specific-description> id=lock<lock-hex-address> mode=<mode> associatedObjectId=<associated-obj-id>               <type-specific-description> can be:• For DATABASE: databaselock subresource=<databaselock-subresource> dbid=<db-id>• For FILE: filelock fileid=<file-id> subresource=<filelock-subresource> dbid=<db-id>• For OBJECT: objectlock lockPartition=<lock-partition-id> objid=<obj-id> subresource=<objectlock-subresource> dbid=<db-id>• For PAGE: pagelock fileid=<file-id> pageid=<page-id> dbid=<db-id> subresource=<pagelock-subresource>• For Key: keylock  hobtid=<hobt-id> dbid=<db-id>• For EXTENT: extentlock fileid=<file-id> pageid=<page-id> dbid=<db-id>• For RID: ridlock fileid=<file-id> pageid=<page-id> dbid=<db-id>• For APPLICATION: applicationlock hash=<hash> databasePrincipalId=<role-id> dbid=<db-id>• For METADATA: metadatalock subresource=<metadata-subresource> classid=<metadatalock-description> dbid=<db-id>• For HOBT: hobtlock hobtid=<hobt-id> subresource=<hobt-subresource> dbid=<db-id>• For ALLOCATION_UNIT: allocunitlock hobtid=<hobt-id> subresource=<alloc-unit-subresource> dbid=<db-id> <mode> can be:• Sch-S• Sch-M• S• U• X• IS• IU• IX• SIU• SIX• UIX• BU• RangeS-S• RangeS-U• RangeI-N• RangeI-S• RangeI-U• RangeI-X• RangeX-S• RangeX-U• RangeX-X External resource owner:•       External ExternalResource=<wait-type> Generic resource owner:•       TransactionMutex TransactionInfo Workspace=<workspace-id>•       Mutex•       CLRTaskJoin•       CLRMonitorEvent•       CLRRWLockEvent•       resourceWait Latch resource owner:•       <db-id>:<file-id>:<page-in-file>•       <GUID>•       <latch-class> (<latch-address>)   Further Information Slava Oks's weblog: sys.dm_os_waiting_tasks.Informit.com: Identifying Blocking Using sys.dm_os_waiting_tasks - Ken Henderson   - Guy

  • I Could Sure Use Some Windows Azure Code Samples…

    - by BuckWoody
    There are multiple ways to learn, and one of the most effective is with examples. You have multiple options with Windows Azure, including the Software Development Kit, the Windows Azure Training Kit and now another one…. the Microsoft All-In-One Code Framework,, a free, centralized code sample library driven by developers' real-world pains and needs. The goal is to provide customer-driven code samples for all Microsoft development technologies, and Windows Azure is included. Once you hit the site, you download an EXE that will create a web-app based installer for a Code Browser.   Once inside, you can configure where the samples store data and other settings, and then search for what you want.   You can also request a sample – if enough people ask, we do it. OneCode also partnered with gallery and Visual Studio team to develop this Sample Browser Visual Studio extension.  It’s an easy way for developers to find and download samples from within Visual Studio.

  • Learning PostgreSql: bulk loading data

    - by Alexander Kuznetsov
    In this post we shall start loading data in bulk. For better performance of inserts, we shall load data into a table without constraints and indexes. This sounds familiar. There is a bulk copy utility, and it is very easy to invoke from C#. The following code feeds the output from a T-SQL stored procedure into a PostgreSql table: using ( var pgTableTarget = new PgTableTarget ( PgConnString , "Data.MyPgTable" , GetColumns ())) using ( var conn = new SqlConnection ( connectionString )) { conn.Open...(read more)

  • Watch @marcorus and @ferrarialberto sessions online #teched #msteched #tee2012

    - by Marco Russo (SQLBI)
    In June I participated to two TechEd editions (North America and Europe). I and Alberto delivered a Pre Conference and two sessions about Tabular. Both conferences provides recorded sessions freely available on Channel 9 so that you can compare which one has been delivered in the best way! If you have to choose between the two versions, consider that in North America we receive more questions during and after the session (still recording), increasing the interaction, whereas in Europe questions usually comes after the session finished (so no recording available). If you’re curious, watch both and let me know which version you prefer, especially for Multidimensional vs Tabular! BISM: Multidimensional vs. Tabular (TechEd North America 2012) BISM: Multidimensional vs. Tabular (TechEd Europe 2012) Many-to-Many Relationships in BISM Tabular (TechEd North America 2012) Many-to-Many Relationships in BISM Tabular (TechEd Europe 2012) If you are interested to learn SSAS Tabular, don’t miss the next SSAS Tabular Workshop online on September 3-4, 2012. We are also planning dates for another roadshow in Europe this fall and I’m happy to announce we’ll have two dates in Germany, too. More updates in the coming weeks.

  • Merge Join component sorted outputs [SSIS]

    - by jamiet
    One question that I have been asked a few times of late in regard to performance tuning SSIS data flows is this: Why isn’t the Merge Join output sorted (i.e.IsSorted=True)? This is a fair question. After all both of the Merge Join inputs are sorted, hence why wouldn’t the output be sorted as well? Well here’s a little secret, the Merge Join output IS sorted! There’s a caveat though – it is only under certain circumstances and SSIS itself doesn’t do a good job of informing you of it. Let’s take a look at an example. Here we have a dataflow that consumes data from the [AdventureWorks2008].[Sales].[SalesOrderHeader] & [AdventureWorks2008].[Sales].[SalesOrderDetail] tables then joins them using a Merge Join component: Let’s take a look inside the editor of the Merge Join: We are joining on the [SalesOrderId] field (which is what the two inputs just happen to be sorted upon). We are also putting [SalesOrderHeader].[SalesOrderId] into the output. Believe it or not the output from this Merge Join component is sorted (i.e. has IsSorted=True) but unfortunately the Merge Join component does not have an Advanced Editor hence it is hidden away from us. There are a couple of ways to prove to you that is the case; I could open up the package XML inside the .dtsx file and show you the metadata but there is an easier way than that – I can attach a Sort component to the output. Take a look: Notice that the Sort component is attempting to sort on the [SalesOrderId] column. This gives us the following warning: Validation warning. DFT Get raw data: {992B7C9A-35AD-47B9-A0B0-637F7DDF93EB}: The data is already sorted as specified so the transform can be removed. The warning proves that the output from the Merge Join is sorted! It must be noted that the Merge Join output will only have IsSorted=True if at least one of the join columns is included in the output. So there you go, the Merge Join component can indeed produce a sorted output and that’s very useful in order to avoid unnecessary expensive Sort operations downstream. Hope this is useful to someone out there! @Jamiet  P.S. Thank you to Bob Bojanic on the SSIS product team who pointed this out to me!

  • More info: a "stand-alone" installer for Management Studio Express 2008

    - by AaronBertrand
    Last February, I blogged about something I was initially very happy about: a stand-alone installer for Management Studio Express (SSMSE) 2008 . Now users could allegedly download a much smaller installer, and only install the client tools without having to install an instance of SQL Server Express. While the latter is true, the former remains a pipe dream. Bill Ramos stated in his 2009-02-20 announcement : "We teased out the Tools portion of SQL Server 2008 Express with Tools into it’s own download."...(read more)

  • SSAS Maestro Training in July 2012 #ssasmaestro #ssas

    - by Marco Russo (SQLBI)
    A few hours ago Chris Webb blogged about SSAS Maestro and I’d like to propagate the news, adding also some background info. SSAS Maestro is the premier certification on Analysis Services that selects the best experts in Analysis Services around the world. In 2011 Microsoft organized two rounds of training/exams for SSAS Maestros and up to now only 11 people from the first wave have been announced – around 10% of attendees of the course! In the next few days the new Maestros from the second round should be announced and this long process is caused by many factors that I’m going to explain. First, the course is just a step in the process. Before the course you receive a list of topics to study, including the slides of the course. During the course, students receive a lot of information that might not have been included in the slides and the best part of the course is class interaction. Students are expected to bring their experience to the table and comparing case studies, experiences and having long debates is an important part of the learning process. And it is also a part of the evaluation: good questions might be also more important than good answers! Finally, after the course, students have their homework and this may require one or two months to be completed. After that, a long (very long) evaluation process begins, taking into account homework, labs, participation… And for this reason the final evaluation may arrive months later after the course. We are going to improve and shorten this process with the next courses. The first wave of SSAS Maestro had been made by invitation only and now the program is opening, requiring a fee to participate in order to cover the cost of preparation, training and exam. The number of attendees will be limited and candidates will have to send their CV in order to be admitted to the course. Only experienced Analysis Services developers will be able to participate to this challenging program. So why you should do that? Well, only 10% of students passed the exam until now. So if you need 100% guarantee to pass the exam, you need to study a lot, before, during and after the course. But the course by itself is a precious opportunity to share experience, create networking and learn mission-critical enterprise-level best practices that it’s hard to find written on books. Oh, well, many existing white papers are a required reading *before* the course! The course is now 5 days long, and every day can be *very* long. We’ll have lectures and discussions in the morning and labs in the afternoon/evening. Plus some more lectures in one or two afternoons. A heavy part of the course is about performance optimization, capacity planning, monitoring. This edition will introduce also Tabular models, and don’t expect something you might find in the SSAS Tabular Workshop – only performance, scalability monitoring and optimization will be covered, knowing Analysis Services is a requirement just to be accepted! I and Chris Webb will be the teachers for this edition. The course is expensive. Applying for SSAS Maestro will cost around 7000€ plus taxes (reduced to 5000€ for students of a previous SSAS Maestro edition). And you will be locked in a training room for the large part of the week. So why you should do that? Well, as I said, this is a challenging course. You will not find the time to check your email – the content is just too much interesting to think you can be distracted by something else. Another good reason is that this course will take place in Italy. Well, the course will take place in the brand new Microsoft Innovation Campus, but in general we’ll be able to provide you hints to get great food and, if you are willing to attach one week-end to your trip, there are plenty of places to visit (and I’m not talking about the classic Rome-Florence-Venice) – you might really need to relax after such a week! Finally, the marking process after the course will be faster – we’d like to complete the evaluation within three months after the course, considering that 1-2 months might be required to complete the homework. If at this point you are not scared: registration will open in mid-April, but you can already write to [email protected] sending your CV/resume and a short description of your level of SSAS knowledge and experience. The selection process will start early and you may want to put your admission form on top of the FIFO queue!

  • The Red Gate Guide to SQL Server Team based Development Free e-book

    - by Mladen Prajdic
    After about 6 months of work, the new book I've coauthored with Grant Fritchey (Blog|Twitter), Phil Factor (Blog|Twitter) and Alex Kuznetsov (Blog|Twitter) is out. They're all smart folks I talk to online and this book is packed with good ideas backed by years of experience. The book contains a good deal of information about things you need to think of when doing any kind of multi person database development. Although it's meant for SQL Server, the principles can be applied to any database platform out there. In the book you will find information on: writing readable code, documenting code, source control and change management, deploying code between environments, unit testing, reusing code, searching and refactoring your code base. I've written chapter 5 about Database testing and chapter 11 about SQL Refactoring. In the database testing chapter (chapter 5) I cover why you should test your database, why it is a good idea to have a database access interface composed of stored procedures, views and user defined functions, what and how to test. I talk about how there are many testing methods like black and white box testing, unit and integration testing, error and stress testing and why and how you should do all those. Sometimes you have to convince management to go for testing in the development lifecycle so I give some pointers and tips how to do that. Testing databases is a bit different from testing object oriented code in a way that to have independent unit tests you need to rollback your code after each test. The chapter shows you ways to do this and also how to avoid it. At the end I show how to test various database objects and how to test access to them. In the SQL Refactoring chapter (chapter 11) I cover why refactor and where to even begin refactoring. I also who you a way to achieve a set based mindset to solve SQL problems which is crucial to good SQL set based programming and a few commonly seen problems to refactor. These problems include: using functions on columns in the where clause, SELECT * problems, long stored procedure with many input parameters, one subquery per condition in the select statement, cursors are good for anything problem, using too large data types everywhere and using your data in code for business logic anti-pattern. You can read more about it and download it here: The Red Gate Guide to SQL Server Team-based Development Hope you like it and send me feedback if you wish too.
