• sort mysql query by filtered query

  - by kalpaitch

  I have two mysql queries: $sql = "SELECT * FROM content WHERE threadName LIKE '%$filter%' ORDER BY lastUpdated desc"; and $sql = "SELECT * FROM content ORDER BY lastUpdated desc"; The end result is to have all rows returned from a particular table 'content' but have those that match the variable $filter at the top. Is there either a single query that could combine these two or should I be using a JOIN?

• Why don't I have a "Web Service References" menu item in excel/VBA?

  - by Draemon

  I'm trying to consume a SOAP web service from excel. Now according to This article (and confirmed by other articles and MSDN) if I do the following: Install the web services toolkit (I've installed v2.01) Install SOAP Toolkit 3.0 Add a reference to Microsoft Soap Type Library (I've tried v3.0 and an older one) I should get a "Web Service References" menu item in the Tools menu but I don't. I've also tried adding every reference that seemed to have anything to do with SOAP or XML, but it hasn't helped. Any ideas?

• How do you manage large web farms?

  - by Andrew Katz

  I have a quickly growing web farm running IIS 7 (30+ servers). All servers are identical copies of each other and all servers are physical. We update the software about once a month, and in the current process, we follow the following steps: Disable server from pool on F5 load balancer. Disable HTTP Keep-alives in IIS so connections drop quickly. Change default directory of website to new folder containing new binaries. Test server Enable HTTP Keep-alives. Enable server in F5 pool. Move to server 2 Microsoft used to have Application Center which was abandoned a while ago. They have made a second attempt with the Web Farm Framework, but this adds as much QA time testing the release package as it saves in the deployment. Has anyone seen a commercial off the shelf application that is tailored for managing and deploying to large web farms? Thanks!

• Excel: How do I copy hyperlink address from one column of text to another column with different text?

  - by OfficeLackey

  I have a spreadsheet where column A displays names in a certain format. There are 200-odd names and each has a different hyperlink (which links to that person's web page). I want to reformat the name order so it is "Surname, Name" rather than "Name Surname" and retain the hyperlink in the newly formatted column. I have achieved "Surname, Name" easily by splitting the names into two columns (using LEFT and RIGHT formulae) - forename and surname - then I have a new column with a formula to return "Surname, Name." However, the hyperlinks are not in that new column and I need them. I don't want to do this manually, for obvious reasons. I cannot find a way of copying just hyperlinks from column A without copying the text from column A. So, effectively, what I need is some sort of macro to take, for example, the hyperlink from A2 and copy it to H2, with H2 still retaining the updated ordering of name. I don't have the knowledge to write this myself, so would appreciate solutions.

• What Technology can Render Medium Scale 3d Environments in a Web-Browser

  - by JakeM

  I intend to make a web application that displays 3d environments that can be navigated by dragging(with a finger or mouse depending on the platform). The web app will render 3d environments of development sites including contours, water pipeline locations, buildings etc. I am trying to decide what technology/libraries to use that will create a web-app that will work on Android-Web-Browser, iOS-Safari, IE9, Safari, Firefox and Chrome. And also what technology will provide speed in development. I understand that this is 'asking for my cake and eating it too'/'asking for the moon' but I don't know all the technologies out there - so there may be advanced libraries that can render 3d environments across many web-browsers including the main smart phone ones and I dont know of them. The 3d rendering would not be highly detailed buildings or water with effects, but rather simple 3d representations of these objects. The environment would be navigable by dragging around and you could view the landscape in layers(view only contour lines, view only underground pipelines, view only sewerage pipes, etc.). Are there any 3d libraries for web-browsers out there? Is there a way to run OpenGL(or OpenGL ES) through a webbrowser? What technology would you use if you were making this kind of app/web app that should work on desktop Windows, Android, iOS and WindowsPhone? Is there any technology I have failed to mention that would be good for this kind of project? I am tending towards a Browser Driven Web App because I get that cross platform ability(where it even works on linux and MacOS by using compatible web-browsers). Also I know of CSS3 transforms that can create cubes that can rotate in 3d space(NOTE only works for WebKit browsers - so no IE :( ). But I don't know if CSS3 is robust enough to render whole 3d environments? Do you think it could? Maybe I could use HTML5 canvas's for this? Can Google maps create custom 3d maps?

• Modular Web App Network Architecture

  - by nairware

  Assuming that I am dealing with dedicated physical servers or VPSs, is it conceivable and does it make sense to have distinct servers setup with the following roles to host a web application? Reverse Proxy Web server Application server Database server Specific points of interest: I am confused how to even separate the web and application servers. My understanding was that such 3-tier architectures were feasible. It is unclear to me if the app server would reside directly between the web and database server, or if the web server could directly interact with the database as well. The app server could either do the computational heavy-lifting on behalf of the app server or it could do heavy-lifting plus control all of the business logic (as implied in the diagram above, thus denying the web server of direct database access). I am also unsure what role the reverse proxy (ex. nginx) could and should fulfill as a web server, given the above mentioned setup. I know that nginx has web server features. But I do not know if it makes sense to have the reverse proxy be its own VPS, given that the web server–in theory–would be separate from the app server.

• SQL SERVER – Display Datetime in Specific Format – SQL in Sixty Seconds #033 – Video

  - by pinaldave

  A very common requirement of developers is to format datetime to their specific need. Every geographic location has different need of the date formats. Some countries follow the standard of mm/dd/yy and some countries as dd/mm/yy. The need of developer changes as geographic location changes. In SQL Server there are various functions to aid this requirement. There is function CAST, which developers have been using for a long time as well function CONVERT which is a more enhanced version of CAST. In the latest version of SQL Server 2012 a new function FORMAT is introduced as well. In this SQL in Sixty Seconds video we cover two different methods to display the datetime in specific format. 1) CONVERT function and 2) FORMAT function. Let me know what you think of this video. Here is the script which is used in the video: -- http://blog.SQLAuthority.com -- SQL Server 2000/2005/2008/2012 onwards -- Datetime SELECT CONVERT(VARCHAR(30),GETDATE()) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),10) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),110) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),5) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),105) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),113) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),114) AS DateConvert; GO -- SQL Server 2012 onwards -- Various format of Datetime SELECT CONVERT(VARCHAR(30),GETDATE(),113) AS DateConvert; SELECT FORMAT ( GETDATE(), 'dd mon yyyy HH:m:ss:mmm', 'en-US' ) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),114) AS DateConvert; SELECT FORMAT ( GETDATE(), 'HH:m:ss:mmm', 'en-US' ) AS DateConvert; GO -- Specific usage of Format function SELECT FORMAT(GETDATE(), N'"Current Time is "dddd MMMM dd, yyyy', 'en-US') AS CurrentTimeString; This video discusses CONVERT and FORMAT in simple manner but the subject is much deeper and there are lots of information to cover along with it. I strongly suggest that you go over related blog posts in next section as there are wealth of knowledge discussed there.

• SQL SERVER – Select and Delete Duplicate Records – SQL in Sixty Seconds #036 – Video

  - by pinaldave

  Developers often face situations when they find their column have duplicate records and they want to delete it. A good developer will never delete any data without observing it and making sure that what is being deleted is the absolutely fine to delete. Before deleting duplicate data, one should select it and see if the data is really duplicate. In this video we are demonstrating two scripts – 1) selects duplicate records 2) deletes duplicate records. We are assuming that the table has a unique incremental id. Additionally, we are assuming that in the case of the duplicate records we would like to keep the latest record. If there is really a business need to keep unique records, one should consider to create a unique index on the column. Unique index will prevent users entering duplicate data into the table from the beginning. This should be the best solution. However, deleting duplicate data is also a very valid request. If user realizes that they need to keep only unique records in the column and if they are willing to create unique constraint, the very first requirement of creating a unique constraint is to delete the duplicate records. Let us see how to connect the values in Sixty Seconds: Here is the script which is used in the video. USE tempdb GO CREATE TABLE TestTable (ID INT, NameCol VARCHAR(100)) GO INSERT INTO TestTable (ID, NameCol) SELECT 1, 'First' UNION ALL SELECT 2, 'Second' UNION ALL SELECT 3, 'Second' UNION ALL SELECT 4, 'Second' UNION ALL SELECT 5, 'Second' UNION ALL SELECT 6, 'Third' GO -- Selecting Data SELECT * FROM TestTable GO -- Detecting Duplicate SELECT NameCol, COUNT(*) TotalCount FROM TestTable GROUP BY NameCol HAVING COUNT(*) > 1 ORDER BY COUNT(*) DESC GO -- Deleting Duplicate DELETE FROM TestTable WHERE ID NOT IN ( SELECT MAX(ID) FROM TestTable GROUP BY NameCol) GO -- Selecting Data SELECT * FROM TestTable GO DROP TABLE TestTable GO Related Tips in SQL in Sixty Seconds: SQL SERVER – Delete Duplicate Records – Rows SQL SERVER – Count Duplicate Records – Rows SQL SERVER – 2005 – 2008 – Delete Duplicate Rows Delete Duplicate Records – Rows – Readers Contribution Unique Nonclustered Index Creation with IGNORE_DUP_KEY = ON – A Transactional Behavior What would you like to see in the next SQL in Sixty Seconds video?

• SQL SERVER – Rename Columnname or Tablename – SQL in Sixty Seconds #032 – Video

  - by pinaldave

  We all make mistakes at some point of time and we all change our opinion. There are quite a lot of people in the world who have changed their name after they have grown up. Some corrected their parent’s mistake and some create new mistake. Well, databases are not protected from such incidents. There are many reasons why developers may want to change the name of the column or table after it was initially created. The goal of this video is not to dwell on the reasons but to learn how we can rename the column and table. Earlier I have written the article on this subject over here: SQL SERVER – How to Rename a Column Name or Table Name. I have revised the same article over here and created this video. There is one very important point to remember that by changing the column name or table name one creates the possibility of errors in the application the columns and tables are used. When any column or table name is changed, the developer should go through every place in the code base, ad-hoc queries, stored procedures, views and any other place where there are possibility of their usage and change them to the new name. If this is one followed up religiously there are quite a lot of changes that application will stop working due to this name change.  One has to remember that changing column name does not change the name of the indexes, constraints etc and they will continue to reference the old name. Though this will not stop the show but will create visual un-comfort as well confusion in many cases. Here is my question back to you – have you changed ever column name or table name in production database (after project going live)? If yes, what was the scenario and need of doing it. After all it is just a name. Let me know what you think of this video. Here is the updated script. USE tempdb GO CREATE TABLE TestTable (ID INT, OldName VARCHAR(20)) GO INSERT INTO TestTable VALUES (1, 'First') GO -- Check the Tabledata SELECT * FROM TestTable GO -- Rename the ColumnName sp_RENAME 'TestTable.OldName', 'NewName', 'Column' GO -- Check the Tabledata SELECT * FROM TestTable GO -- Rename the TableName sp_RENAME 'TestTable', 'NewTable' GO -- Check the Tabledata - Error SELECT * FROM TestTable GO -- Check the Tabledata - New SELECT * FROM NewTable GO -- Cleanup DROP TABLE NewTable GO Related Tips in SQL in Sixty Seconds: SQL SERVER – How to Rename a Column Name or Table Name What would you like to see in the next SQL in Sixty Seconds video?

Question of the Day: Which of the following queries will return dirty data? a) SELECT * FROM Table1 (READUNCOMMITED) b) SELECT * FROM Table1 (NOLOCK) c) SELECT * FROM Table1 (DIRTYREAD) d) SELECT * FROM Table1 (MYLOCK) Query Hints: BIG HINT POST Most SQL people know what a “Dirty Record” is. You might also call that an “Intermediate record”. In case this is new to you here is a very quick explanation. The simplest way to describe the steps of a transaction is to use an example of updating an existing record into a table. When the insert runs, SQL Server gets the data from storage, such as a hard drive, and loads it into memory and your CPU. The data in memory is changed and then saved to the storage device. Finally, a message is sent confirming the rows that were affected. For a very short period of time the update takes the data and puts it into memory (an intermediate state), not a permanent state. For every data change to a table there is a brief moment where the change is made in the intermediate state, but is not committed. During this time, any other DML statement needing that data waits until the lock is released. This is a safety feature so that SQL Server evaluates only official data. For every data change to a table there is a brief moment where the change is made in this intermediate state, but is not committed. During this time, any other DML statement (SELECT, INSERT, DELETE, UPDATE) needing that data must wait until the lock is released. This is a safety feature put in place so that SQL Server evaluates only official data. Additional Hints: I have previously discussed various concepts from SQL Server Joes 2 Pros Volume 1.

• Excel Solver vs Solver Foundation

  - by JoshReuben

  I recently read a book http://www.amazon.com/Scientific-Engineering-Cookbook-Cookbooks-OReilly/dp/0596008791/ref=sr_1_1?ie=UTF8&s=books&qid=1296593374&sr=8-1 - the Excel Scientific and Engineering Cookbook.     The 2 main tools that this book leveraged were the Data Analysis Pack and Excel Solver. I had previously been aquanted with Microsoft Solver Foundation - this is a full fledged API for solving optimization problems, and went beyond being a mere Excel plugin - it exposed a C# programmatic interface for in process and a web service interface for out of process integration. were they the same? apparently not!   2 different solver frameworks for Excel: http://www.solver.com/index.html http://www.solverfoundation.com/ I contacted both vendors to get their perspectives.   Heres what the Excel Solver guys had to say:   "The Solver Foundation requires you to learn and use a very specific modeling language (OML). The Excel solver allows you to formulate your optimization problems without learning any new language simply by entering the formulas into cells on the Excel spreadsheet, something that nearly everyone is already familiar with doing.   The Excel Solver also allows you to seamlessly upgrade to products that combine Monte Carlo Simulation capabilities (our Risk Solver Premium and Risk Solver Platform products) which allow you to include uncertainty into your models when appropriate.   Our advanced Excel Solver Products also have a number of built in reporting tools for advanced analysis of the your model and it's results"           And Heres what the Microsoft Solver Foundation guys had to say:   "  With the release of Solver Foundation 3.0, Solver Foundation has the same kinds of solvers (plus a few more) than what is found in Excel Solver. I think there are two main differences:   1.      Problems are described differently. In Excel Solver the goals and constraints are specified inside the spreadsheet, in formulas. In Solver Foundation they are described either in .Net code that uses the Solver Foundation Services API, or using the OML modeling language in Excel. 2.      Solver Foundation’s primary strength is on solving large linear, mixed integer, and constraint models. That is, models that contain arbitrary nonlinear functions (such as trig functions, IF(), powers, etc) are handled a bit better by the Excel Solver at this point. "

  I have got some work from my friend for updating his website. Earlier his website was made by some other person and he used to maintain all the stuff. Now that developer has given only the ftp username and password to my friend. He asks me to update his website. But the problem is I don't know how to access the things for this particular web hosting account like knowing the available free space, accesing email account, etc. I asked him about website control panel but he says that he doesn't know about. Is there any other site/client program/control panel that I can use to manage that website. So can any one help me out?

• 255 Character limit on VLOOKUP

  - by zod

  Using excel 2003, the formula: =VLOOKUP(D1 ,A1:B135, 2) fails if the length of D1 exceeds 255 characters (i.e. the list has some text longer then 255 characters, D1 has the same text value, and VLOOKUP returns #VALUE!). MATCH seems to suffer from the same character limit. I cannot find any official confirmation of these limits, for example here: http://office.microsoft.com/en-us/excel-help/vlookup-HP005209335.aspx or here: http://office.microsoft.com/en-us/excel-help/excel-specifications-and-limits-HP005199291.aspx?CTT=3 I know that excel has a 255 limit on the length of text used in formulae, but it suggests connate should work (it does not in this case, and I am not using strings in the formula, but referencing another cell). Can somebody confirm that these limit exist (it is always possible I am doing something else wrong)? More importantly, does anyone know of a way around them? Thanks

• How can you become a competent web application security expert without breaking the law?

  - by hal10001

  I find this to be equivalent to undercover police officers who join a gang, do drugs and break the law as a last resort in order to enforce it. To be a competent security expert, I feel hacking has to be a constant hands-on effort. Yet, that requires finding exploits, testing them on live applications, and being able to demonstrate those exploits with confidence. For those that consider themselves "experts" in Web application security, what did you do to learn the art without actually breaking the law? Or, is this the gray area that nobody likes to talk about because you have to bend the law to its limits?

  Today’s SQL in Sixty Seconds video is inspired from my presentation at TechEd India 2012 on Speed up! – Parallel Processes and Unparalleled Performance. There are always special cases when it is about SQL Server. There are always few queries which gives optimal performance when they are executed on single processor and there are always queries which gives optimal performance when they are executed on multiple processors. I will be presenting the how to identify such queries as well what are the best practices related to the same. In this quick video I am going to demonstrate if the query is giving optimal performance when running on single CPU how one can restrict queries to single CPU by using hint OPTION (MAXDOP 1).

  I have my own idea for a web application, and I am not a programmer. The application will work similar to Facebook and Twitter, profiles and feeds. I have learned some computer science theory, all the way up to OOP, but have no practical experience. Without any experience, is there a way I can evaluate the different language and platform choices available to me? What kind of things should I be looking at? Ease of setup? How many followers it has? How can I evaluate whether a language will have the capabilities I need?

• Dynamic URL of asp.net web service with web reference

  - by Jalpesh P. Vadgama

  It’s been a while I am writing this. But never late.. So I am writing this. Before some time one of friend asked about the URL of web service when we add reference. So I am writing this. Some of you may find this very basic but still many of people does not know this that’s why I am writing this. In today’s world we have so many servers like development, preproduction and production etc. and for all the server location or URL of web service will be different.But with asp.net when you add a web reference to your web application it’s create a web reference settings in web.config where you can change this path. So it’s very easy to just change that path and you don’t have to add web reference again. Read More

• Coding a web browser on Windows using a layout engine?

  - by samual johnson

  I've never attempted anything like this before but what I want to do is code a browser for Windows. I know that I can use the web-browser control that Microsoft has released, but I'm interested in seeing how the problem is solved from a lower level. So I want to know what layout engine I should be looking at? Or is a layout engine the best way to go? I've been looking at WebKit, but it seems rather Mac-centric, so I'm wondering if there are any more practical one's for windows? Has Microsoft released the source code for their webbrowser winforms control in the .Net framework? That would be dependent on the CLR anyway, I suppose? Any suggestions?

• Convert Excel File 'xls' to CSV, CAUTION: Bumps Ahead

  - by faizanahmad

  The task was to provide users with an interface where they can upload the 'csv' files, these files were to be processed and loaded to Database by a Console application. The code in Console application could not handle the 'xls' files so we thought, OK, lets convert 'xls' to 'csv' in the code, Seemed like fun. The idea was to convert it right after uploading within 'csv' file. As Microsoft does not recommend using the  Excel objects in ASP.NET, we decided to use the Jet engine to open xls. (Ace driver is used for xlsx) The code was pretty straight, can be found on following links: http://www.c-sharpcorner.com/uploadfile/yuanwang200409/102242008174401pm/1.aspx http://www.devasp.net/net/articles/display/141.html FIRST BUMP 'OleDbException (0x80004005): Unspecified error' ( Impersonation ): The ablove code ran fine in my test web site and test console application, but it gave an 'OleDbException (0x80004005): Unspecified error' in main web site, turns out imperonation was set to True and as soon as I changed it to False, it did work. on My XP box, web site was running under user                   'ASPNET'  with imperosnation set to FALSE                   'IUSR_*' i.e IIS guest user with impersonation set to TRUE The weired part was that both users had same rights on the folders I was saving files to and on Excel app in DCOM Config.  We decided to give it a try on Windows Server 2003 with web site set to windows authentication ( impersonation = true ) and yes it did work. SECOND BUMP 'External table not in correct format': I got this error with some files and it appeared that the file from client has some metadata issues  ( when I opened the file in Excel and try to save it ,excel  would give me this error saying File can not be saved in current format ) and the error was caused by that. Some people were able to reslove the error by using "Extended Properties=HTML Import;" in connection string. But it did not work for me. We decided to detour from here and use Excel object :( as we had no control on client setting the meta deta of Excel files. Before third bump there were a ouple of small thingies like 'Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005' Fix can be found at http://blog.crowe.co.nz/archive/2006/03/02/589.aspx THIRD BUMP ( Could not get rid of the EXCEL process  ):  I has all the code in place to 'Quiet' the excel, but, it just did not work. work around was done to Kill the process as we knew no other application on server was using EXCEL.  The normal steps to quite the excel application worked just fine in console application though.   FOURTH BUMP: Code worked with one file 1 on my machine and with the other file 2 code will break. and the same code will work perfectly fine with file 2 on some other machine . We moved it to QA  ( Windows Server 2003 )and worked with every file just perfect. But , then there was another problem: one user can upload it and second cant, permissions on folder and DCOM Conifg checked. Another Detour: Uplooad the xls as it is and convert in Console application.   Lesson Learnt:  If its 'xlsx' use 'ACE Driver' or read xml within excel as recommneded by MS. If xls and you know its always going to be properly formatted  'jet Engine'  Code: Imports Microsoft.Office.Interop Private Function ConvertFile(ByVal SourceFolder As String, ByVal FileName As String, ByVal FileExtension As String)As Boolean     Dim appExcel As New Excel.Application     Dim workBooks As Excel.Workbooks = appExcel.Workbooks     Dim objWorkbook As Excel.Workbook      Try                   objWorkbook = workBooks.Open(CompleteFilePath )                            objWorkbook.SaveAs(Filename:=CObj(SourceFolder & FileName & ".csv"), FileFormat:=Excel.XlFileFormat.xlCSV)       Catch ex As Exception         GenerateAlert(ex.Message().Replace("'", "") & " Error Converting File to CSV.")         LogError(ex )         Return False      Finally                      If Not(objWorkbook is Nothing) then               objWorkbook.Close(SaveChanges:=CObj(False))           End If           ReleaseObj(objWorkbook)                                      ReleaseObj(workBooks)           appExcel.Quit()           ReleaseObj(appExcel)                                 Dim proc As System.Diagnostics.Process           For Each proc In System.Diagnostics.Process.GetProcessesByName("EXCEL")               proc.Kill()           Next         DeleteSourceFile(SourceFolder & FileName & FileExtension)     End Try  Return True  End Function   Private Sub ReleaseObj(ByVal o As Object)     Try      System.Runtime.InteropServices.Marshal.ReleaseComObject(o)   Catch ex As Exception           LogError(ex )   Finally      o = Nothing    End Try End Sub     Protected Sub DeleteSourceFile(Byval CompleteFilePath As string)         Try             Dim MyFile As FileInfo = New FileInfo(CompleteFilePath)             If  MyFile.Exists Then                 File.Delete(CompleteFilePath)             Else              Throw New FileNotFoundException()             End If         Catch ex As Exception             GenerateAlert( " Source File could not be deleted.")              LogError(ex)         End Try     End Sub  The code to kill the process ( Avoid it if you can ): Dim proc As System.Diagnostics.Process For Each proc In System.Diagnostics.Process.GetProcessesByName("EXCEL")     proc.Kill() Next

• Responsible BI for Excel, Even for Older Versions

  - by andrewbrust

  On Wednesday, I will have the honor of co-presenting, for both The Data Warehouse Institute (TDWI) and the New York Technology Council. on the subject of Excel and BI. My co-presenter will be none other than Bill Baker, who was a Microsoft Distinguished Engineer and, essentially, the father of BI at that company.  Details on the events are here and here. We'll be talking about PowerPivot, of course, but that's not all. Probably even more important than any one product, will be our discussion of whether the usual characterization of Excel as the nemesis of IT, the guilty pleasure of business users and the antithesis of formal BI is really valid and/or hopelessly intractable. Without giving away our punchline, I'll tell you that we are much more optimistic than that. There are huge upsides to Excel and while there are real dangers to using it in the BI space, there are standards and practices you can employ to ensure Excel is used responsibly. And when those practices are followed, Excel becomes quite powerful indeed. One of the keys to this is using Excel as a data consumer rather than data storage mechanism. Caching data in Excel is OK, but only if that data is (a) not modified and (b) configured for automated periodic refresh. PowerPivot meets both criteria -- it stores a read-only copy of your data in the form of a model, and once workbook containing a PowerPivot model is published to SharePoint, it can be configured for scheduled data refresh, on the server, requiring no user intervention whatsoever. Data refresh is a bit like hard drive backup: it will only happen reliably if it's automated, and super-easy to configure. PowerPivot hits a real home run here (as does Windows Home Server for PC backup, but I digress). The thing about PowerPivot is that it's an add-in for Excel 2010. What if you're not planning to go to that new version for quite a while? What if you’ve just deployed Office 2007 in your organization? What if you're still on Office 2003, or an even earlier version? What can you do immediately to share data responsibly and easily? As it turns out, there's a feature in Excel that's been around for quite a while, that can help: Web Queries.  The Web Query feature was introduced, ostensibly, to allow Excel to pull data in from Internet Web pages…for example, data in a stock quote history table will come in nicely, as will any data in a Web page that is displayed in an HTML table.  To use the feature In Excel 2007 or 2010, click the Data Tab or the ribbon and click the “From Web” button towards the left; in older versions use the corresponding option in  the menu or  toolbars.  Next, paste a URL into the resulting dialog box and tap Enter or click the Go button.  A preview of the Web page will come up, and the dialog will allow you to select the specific table within the page whose data you’d like to import.  Here’s an example: Now just click the table, click the Import button, and the Import Data dialog appears.  You can simply click OK to bring in your data or you can first click the Properties… button and configure the data import to be refreshed at an interval in minutes that you select.  Now your data’s in the spreadsheet and ready to worked with: Your data may be vulnerable to modification, but if you’ve set up the data refresh, any accidental or malicious changes will be corrected in time anyway. The thing about this feature is that it’s most useful not for public Web pages, but for pages behind the firewall.  In effect, the Web Query feature provides an incredibly easy way to consume data in Excel that’s “published” from an application.  Users just need a URL.  They don’t need to know server and database names and since the data is read-only, providing credentials may be unnecessary, or can be handled using integrated security.  If that’s not good enough, the Web Query can be saved to a special .iqy file, which can be edited to provide POST parameter data. The only requirement is that the data must be provided in an HTML table, with the first row providing the column names.  From an ASP.NET project, it couldn’t be easier: a simple bound GridView control is totally compatible.  Use a data source control with it, and you don’t even have to write any code.  Users can link to pages that are part of an application’s UI, or developers can create pages that are specially designed for the purpose of providing an interface to the Web Query import feature.  And none of this is Microsoft- or .NET-specific.  You can create pages in any language you want (PHP comes to mind) that output the result set of a query in HTML table format, and then consume that data in a Web Query.  Then build PivotTables and charts on the data, and in Excel 2007 or 2010 you can use conditional formatting to create scorecards and dashboards. This strategy allows you to create pages that function quite similarly to the OData XML feeds rendered when .NET developers create an “Astoria” WCF Data Service.  And while it’s cool that PowerPivot and Excel 2010 can import such OData feeds, it’s good to know that older versions of Excel can function in a similar fashion, and can consume data produced by virtually any Web development platform. As a final matter, instead of just telling you that “older versions” of Excel support this feature, I’ll be more specific.  To discover what the first version of Excel was to support Web queries, go to http://bit.ly/OldSchoolXL.
