  • Slides and Samples for My TechEd / Microsoft BI Conference Talks

    - by plitwin
    I posted the slides and samples for my talks I delivered in New Orleans on June 8th at Microsoft TechEd and Business Intelligence Conference. They can be downloaded from Paul Litwin's Conference Downloads. #1 Creating Report Subscriptions with SQL Server 2008 Reporting Services at 8 AM on Tuesday. Room 241In this session, learn how to set up standard and data-driven subscriptions using Report Manager. We discuss creating file-share, email, and null subscriptions; and how to deal with potential issues with parameters and security. We also demonstrate a sophisticated Microsoft ASP.NET-based application that creates subscriptions by calling the SSRS Web Services API.  #2 ASP.NET MVC for Web Forms Programmers at 3:15 PM Tuesday. Room 391Are you comfortable creating ASP.NET Web Form applications but even a little curious about what all the fuss is about MVC and test-driven development? In this session, Web Form junkie Paul Litwin takes a critical look at the world of ASP.NET MVC, but not from any expert point of view. Instead, Paul shares his experience as a Web Form developer who decided to take a closer look at this radical new approach to ASP.NET development. Come hear what Paul learned and if he plans to employ ASP.NET MVC in his future ASP.NET applications.

  • How to call SQL Function with multiple parameters from C# web page

    - by Marshall
    I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this: String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = @ClientID AND LocationName = @LocationName ',10)"; SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection); Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default"; // Real code uses Location Name from user input SqlDataReader reader = Cmd.ExecuteReader(); When I do this, I get the following code from SQL profiler: exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationID nvarchar(20)', @ClientID=7,@LocationName=N'Default' When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists. exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20); SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationName nvarchar(20)', @ClientID=7,@LocationName=N'Default' I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function. Any ideas?

  • Back From Microsoft Web Camps Beijing

    - by Dixin
    I am just back from Microsoft Web Camps, where Web developers in Beijing had a good time for 2 days with 2 fantastic speakers, Scott Hanselman and James Senior. On day 1, Scott and James talked about Web Platform Installer, ASP.NET core runtime, ASP.NET MVC, Entity Framework, Visual Studio 2010, … They were humorous and smart, and everyone was excited! On day 2, developers were organized into teams to build Web applications. At the end of day 2, each team had a chance of presentation. Before ending, I also demonstrated my so-called “WebOS”, a tiny but funny Web website developed with ASP.NET MVC and jQuery, which looks like an operating system, to show the power of ASP.NET MVC and jQuery. Scott, James and me were joking there, and people cannot help laughing and applauding… You can play with it here: http://www.coolwebos.com/, if interested. I talked with Scott and James about Web and ASP.NET, and asked some questions. I also helped on some English / Chinese translation. At the end Scott gave me a fabulous gift, which I will post to blog later. Hope Microsoft can have more and more events like this!

  • Redistribution of sqlpackage.exe [SSDT]

    - by jamiet
    This is a short note for anyone that may be interested in redistributing sqlpackage.exe. If this isn’t you then no need to keep reading. Ostensibly this is here for anyone that bingles for this information. sqlpackage.exe is a command-line that ships with SQL Server Development Tools (SSDT) in SQL Server 2012 and its main purpose (amongst other things) is to deploy .dacpac files from the command-line. Its quite conceivable that one might want to install only sqlpackage.exe rather than the full SSDT suite (for example on a production server) and I myself have recently had that need. I enquired to the SSDT product team about the possibility of doing this. I said: Back in VS DB Proj days it was possible to use VSDBCMD.exe on a machine that did not have the full VS shell install by shipping lots of pre-requisites along for the ride (details at How to: Prepare a Database for Deployment From a Command Prompt by Using VSDBCMD.EXE). Is there a similar mechanism for using VSDBMCD.exe’s replacement, sqlpackage.exe? here was the reply from Barclay Hill who heads up the development team: Yes, SQLPackage.exe is the analogy of VSDBCMD.exe. You can acquire separately, in a stand-alone package, by installing DACFX. You can get it from: Feature pack is here: http://www.microsoft.com/en-us/download/details.aspx?id=29065 Web Platform Installer here: http://www.microsoft.com/web/gallery/install.aspx?appid=DACFX You will notice it has dependencies on SQLDOM and SQLCLRTYPES.  WebPI will install these for you, but it is al carte on the feature pack. So, now you know. I didn’t enquire about licensing of DACFX but given SSDT is free I am going to assume that the same applies to DACFX too. @Jamiet

  • Upgrading from 2005 to R2

    - by DavidWimbush
    We're about to take the plunge and upgrade our servers from SQL 2005 to SQL 2008 R2. Real world accounts of people upgrading to R2 are a bit hard to find so I thought it might be useful to blog what happens. (I don't count marketing 'case studies' that just say stuff like "The process was effortless and the upgrade will pay for itself by the end the week.") We're using the database engine, Analysis Services and Reporting Services so upgrading by a major version number was looking a bit daunting. I wasn't expecting much trouble on the engine side of things but, as most of the action in 2008 and R2 appears to have been on the Reporting and BI front, I expected to have quite a bit of work to do. But our testing so far has been one nice surprise after another: The 2005 backups restore cleanly onto R2. R2's BI Studio upgraded the Reporting and Analysis Services solutions without any issues. The cubes all deployed and processed just fine. R2 BI Studio interacts fine with TFS 2008 version control. I'll blog some more as things develop.

  • Remote SQL server connection failure

    - by Sevki
    I am trying to connect to my MSSQL server 2008 web instance and im failing horribly... i get the error 26 and before you jump on me i have done these Check the spelling of the SQL Server instance name that is specified in the connection string. Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections over the TCP or named pipes protocols. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. Make sure that you have configured the firewall on the server instance of SQL Server to open ports for SQL Server and the SQL Server Browser port (UDP 1434). Make sure that the SQL Server Browser service is started on the server. in addition to theese i have disabled the firewall completely and tried other ports nothing works the same credentials work on the server but not on the client. this is the exact error message A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (.Net SqlClient Data Provider) Can anybody help?

  • The future for Microsoft

    - by Scott Dorman
    Originally posted on: http://geekswithblogs.net/sdorman/archive/2013/10/16/the-future-for-microsoft.aspxMicrosoft is in the process of reinventing itself. While some may argue that it’s “too little, too late” or that their growing consumer-focused strategy is wrong, the truth of the situation is that Microsoft is reinventing itself into a new company. While Microsoft is now calling themselves a “devices and services” company, that’s not entirely accurate. Let’s look at some facts: Microsoft will always (for the long-term foreseeable future) be financially split into the following divisions: Windows/Operating Systems, which for FY13 made up approximately 24% of overall revenue. Server and Tools, which for FY13 made up approximately 26% of overall revenue. Enterprise/Business Products, which for FY13 made up approximately 32% of overall revenue. Entertainment and Devices, which for FY13 made up approximately 13% of overall revenue. Online Services, which for FY13 made up approximately 4% of overall revenue. It is important to realize that hardware products like the Surface fall under the Windows/Operating Systems division while products like the Xbox 360 fall under the Entertainment and Devices division. (Presumably other hardware, such as mice, keyboards, and cameras, also fall under the Entertainment and Devices division.) It’s also unclear where Microsoft’s recent acquisition of Nokia’s handset division will fall, but let’s assume that it will be under Entertainment and Devices as well. Now, for the sake of argument, let’s assume a slightly different structure that I think is more in line with how Microsoft presents itself and how the general public sees it: Consumer Products and Devices, which would probably make up approximately 9% of overall revenue. Developer Tools, which would probably make up approximately 13% of overall revenue. Enterprise Products and Devices, which would probably make up approximately 47% of overall revenue. Entertainment, which would probably make up approximately 13% of overall revenue. Online Services, which would probably make up approximately 17% of overall revenue. (Just so we’re clear, in this structure hardware products like the Surface, a portion of Windows sales, and other hardware fall under the Consumer Products and Devices division. I’m assuming that more of the income for the Windows division is coming from enterprise/volume licenses so 15% of that income went to the Enterprise Products and Devices division. Most of the enterprise services, like Azure, fall under the Online Services division so half of the Server and Tools income went there as well.) No matter how you look at it, the bulk of Microsoft’s income still comes from not just the enterprise but also software sales, and this really shouldn’t surprise anyone. So, now that the stage is set…what’s the future for Microsoft? The future I see for Microsoft (again, this is just my prediction based on my own instinct, gut-feel and publicly available information) is this: Microsoft is becoming a consumer-focused enterprise company. Let’s look at it a different way. Microsoft is an enterprise-focused company trying to create a larger consumer presence.  To a large extent, this is the exact opposite of Apple, who is really a consumer-focused company trying to create a larger enterprise presence. The major reason consumer-focused companies (like Apple) have started making in-roads into the enterprise is the “bring your own device” phenomenon. Yes, Apple has created some “game-changing” products but their enterprise influence is still relatively small. Unfortunately (for this blog post at least), Apple provides revenue in terms of hardware products rather than business divisions, so it’s not possible to do a direct comparison. However, in the interest of transparency, from Apple’s Quarterly Report (filed 24 July 2013), their revenue breakdown is: iPhone, which for the 3 months ending 29 June 2013 made up approximately 51% of revenue. iPad, which for the 3 months ending 29 June 2013 made up approximately 18% of revenue. Mac, which for the 3 months ending 29 June 2013 made up approximately 14% of revenue. iPod, which for the 3 months ending 29 June 2013 made up approximately 2% of revenue. iTunes, Software, and Services, which for the 3 months ending 29 June 2013 made up approximately 11% of revenue. Accessories, which for the 3 months ending 29 July 2013 made up approximately 3% of revenue. From this, it’s pretty clear that Apple is a consumer-and-hardware-focused company. At this point, you may be asking yourself “Where is all of this going?” The answer to that lies in Microsoft’s shift in company focus. They are becoming more consumer focused, but what exactly does that mean? The biggest change (at least that’s been in the news lately) is the pending purchase of Nokia’s handset division. This, in combination with their Surface line of tablets and the Xbox, will put Microsoft squarely in the realm of a hardware-focused company in addition to being a software-focused company. That can (and most likely will) shift the revenue split to looking at revenue based on software sales (both consumer and enterprise) and also hardware sales (mostly on the consumer side). If we look at things strictly from a Windows perspective, Microsoft clearly has a lot of irons in the fire at the moment. Discounting the various product SKUs available and painting the picture with broader strokes, there are currently 5 different Windows-based operating systems: Windows Phone Windows Phone 7.x, which runs on top of the Windows CE kernel Windows Phone 8.x+, which runs on top of the Windows 8 kernel Windows RT The ARM-based version of Windows 8, which runs on top of the Windows 8 kernel Windows (Pro) The Intel-based version of Windows 8, which runs on top of the Windows 8 kernel Xbox The Xbox 360, which runs it’s own proprietary OS. The Xbox One, which runs it’s own proprietary OS, a version of Windows running on top of the Windows 8 kernel and a proprietary “manager” OS which manages the other two. Over time, Windows Phone 7.x devices will fade so that really leaves 4 different versions. Looking at Windows RT and Windows Phone 8.x paints an interesting story. Right now, all mobile phone devices run on some sort of ARM chip and that doesn’t look like it will change any time soon. That means Microsoft has two different Windows based operating systems for the ARM platform. Long term, it doesn’t make sense for Microsoft to continue supporting that arrangement. I have long suspected (since the Surface was first announced) that Microsoft will unify these two variants of Windows and recent speculation from some of the leading Microsoft watchers lends credence to this suspicion. It is rumored that upcoming Windows Phone releases will include support for larger screen sizes, relax the requirement to have a hardware-based back button and will continue to improve API parity between Windows Phone and Windows RT. At the same time, Windows RT will include support for smaller screen sizes. Since both of these operating systems are based on the same core Windows kernel, it makes sense (both from a financial and development resource perspective) for Microsoft to unify them. The user interfaces are already very similar. So similar in fact, that visually it’s difficult to tell them apart. To illustrate this, here are two screen captures: Other than a few variations (the Bing News app, the picture shown in the Pictures tile and the spacing between the tiles) these are identical. The one on the left is from my Windows 8.1 laptop (which looks the same as on my Surface RT) and the one on the right is from my Windows Phone 8 Lumia 925. This pretty clearly shows that from a consumer perspective, there really is no practical difference between how these two operating systems look and how you interact with them. For the consumer, your entertainment device (Xbox One), phone (Windows Phone) and mobile computing device (Surface [or some other vendors tablet], laptop, netbook or ultrabook) and your desktop computing device (desktop) will all look and feel the same. While many people will denounce this consistency of user experience, I think this will be a good thing in the long term, especially for the upcoming generations. For example, my 5-year old son knows how to use my tablet, phone and Xbox because they all feature nearly identical user experiences. When Windows 8 was released, Microsoft allowed a Windows Store app to be purchased once and installed on as many as 5 devices. With Windows 8.1, this limit has been increased to over 50. Why is that important? If you consider that your phone, computing devices, and entertainment device will be running the same operating system (with minor differences related to physical hardware chipset), that means that I could potentially purchase my sons favorite Angry Birds game once and be able to install it on all of the devices I own. (And for those of you wondering, it’s only 7 [at the moment].) From an app developer perspective, the story becomes even more compelling. Right now there are differences between the different operating systems, but those differences are shrinking. The user interface technology for both is XAML but there are different controls available and different user experience concepts. Some of the APIs available are the same while some are not. You can’t develop a Windows Phone app that can also run on Windows (either Windows Pro or RT). With each release of Windows Phone and Windows RT, those difference become smaller and smaller. Add to this mix the Xbox One, which will also feature a Windows-based operating system and the same “modern” (tile-based) user interface and the visible distinctions between the operating systems will become even smaller. Unifying the operating systems means one set of APIs and one code base to maintain for an app that can run on multiple devices. One code base means it’s easier to add features and fix bugs and that those changes become available on all devices at the same time. It also means a single app store, which will increase the discoverability and reach of your app and consolidate revenue and app profile management. Now, the choice of what devices an app is available on becomes a simple checkbox decision rather than a technical limitation. Ultimately, this means more apps available to consumers, which is always good for the app ecosystem. Is all of this just rumor, speculation and conjecture? Of course, but it’s not unfounded. As I mentioned earlier, some of the prominent Microsoft watchers are also reporting similar rumors. However, Microsoft itself has even hinted at this future with their recent organizational changes and by telling developers “if you want to develop for Xbox One, start developing for Windows 8 now.” I think this pretty clearly paints the following picture: Microsoft is committed to the “modern” user interface paradigm. Microsoft is changing their release cadence (for all products, not just operating systems) to be faster and more modular. Microsoft is going to continue to unify their OS platforms both from a consumer perspective and a developer perspective. While this direction will certainly concern some people it will excite many others. Microsoft’s biggest failing has always been following through with a strong and sustained marketing strategy that presents a consistent view point and highlights what this unified and connected experience looks like and how it benefits consumers and enterprises. We’ve started to see some of this over the last few years, but it needs to continue and become more aggressive and consistent. In the long run, I think Microsoft will be able to pull all of these technologies and devices together into one seamless ecosystem. It isn’t going to happen overnight, but my prediction is that we will be there by the end of 2016. As both a consumer and a developer, I, for one, am excited about the future of Microsoft.

  • SQL Server 2008 - Editing Tables: Bit columns require 'True' or 'False'

    - by CJM
    Not so much a question as an observation... I'm just upgrading to SQL Server 2008 on my development machine in anticipation of upgrading my live applications. I didn't anticipate any problems since [I think] I generally use standard T-SQL, and probably not too far from ANSI standard SQL. So far so good, but I was really thrown by a very simple change: I was creating a simple, small look-up table to store a list of codes and including a bit column to indicate the current default code. But when I used the new/modified 'Edit Top 200 Rows' option, and entered my 0s and 1s in the the bit column I got an error: 'Invalid value for cell - String was not recognised as a valid boolean' After a bit of head-scratching, I tried True and False - and they worked. So it seems this new Edit feature requires 4 or 5 characters to be typed, rather than the previous 1. Checking further, we can still use '...where bitval = 1' but can now also use '...where bitval = 'true''. But any results returned render these bit columns as 0 or 1 still. It all sounds like half a step backwards. Not the end of the world, but and unnecessary annoyance. Does anybody have any insight on this issue? Or there any other new Gotchas with SQL Server 2008?

  • SQL Developer: Describe versus Ctrl+Click to Open Database Objects

    - by thatjeffsmith
    In yesterday’s post I talked about you could use SQL Developer’s Describe (SHIFT+F4) to open a PL/SQL Package at your cursor. You might get an error if you try to describe this… If you actually try to describe the package as you see it in the above screenshot, you’ll get an error: Doh! I neglected to say in yesterday’s post that I was highlighting the package name before I hit SHIFT+F4. This works just fine, but it will work even better in our next release as we’ve fixed this issue. Until then, you can also try the Ctrl+Hover with your mouse. For PL/SQL calls you can open the source immediately based on what you’re hovering over with your mouse cursor. You could try this with “dbms_output.put_line(” too Ctrl+Click, It’s not just for PL/SQL If you don’t like the floating describe windows you get when you do a SHIFT+F4 on a database object, the ctrl+click will work too. Instead of opening a normal ‘hover’ panel, you’ll be taken directly to the object editor for that table, view, etc. Go ahead and try it right now. Paste this into your worksheet, then ctrl+click with your mouse over the table name: select * from scott.emp And now you know, the rest of the story.

  • SQL Server Installaion error 0x84B40000

    - by Kurtevich
    I have a problem installing SQL Server 2008 R2. Long time ago I had it installed, and then uninstalled. It was left in "Add/remove programs", but I didn't pay attention on that. I had 2005 installed. And now there is a need to install 2008. I removed 2005 and started installing 2008, but it says that space on C: is not enough. That's when I found out that "Add/remove programs" shows it occupying more than 4 gigabytes, though I used to uninstall it. So I click "Remove", it shows all those many screens and validations, shows that removal completed, but the size of Program Files folder is still more than 4 GB. I removed (from "Add\remove programs" everything that had "SQL Server" in it's name, but that main "SQL Server 2008" item is still there and still 4 GB and uninstalling does nothing. Because installation of SQL Server did not show existing instances, and I don't see any running services related to SQL server (well, almost any, more details in the end), I though that this folder contains just some leftover staff and data and deleted it manually. Then agreed to removing of the item in "Add/remove programs" and everything looks clean. Now every time I try to install SQL Server (even in the minimum configuration), I receive the following error: SQL Server Setup has encountered the following error: The specified credentials that were provided for the SQL Server service are not valid. To continue, provide a valid account and password for the SQL Server service. Error code 0x84B40000. What is this service mentioned here? This error looks like I'm trying to add features to existing server and it can't login. But the setup didn't ask me for any credentials, except one username that couldn't be changed. Here are the services shown that can be related, both disabled and pointing to non-existing executables: SQL Active Directory Helper Service SQL Full-text Filter Daemon Launcher (MSSQLSERVER) I understand that this must be because of my manual deletion, but is there a way to clean it up now?

  • LINQ-to-SQL IN/Contains() for Nullable<T>

    - by Craig Walker
    I want to generate this SQL statement in LINQ: select * from Foo where Value in ( 1, 2, 3 ) The tricky bit seems to be that Value is a column that allows nulls. The equivalent LINQ code would seem to be: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); var myFoos = from foo in foos where values.Contains(foo.Value) select foo; This, of course, doesn't compile, since foo.Value is an int? and values is typed to int. I've tried this: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); IEnumerable<int?> nullables = values.Select( value => new Nullable<int>(value)); var myFoos = from foo in foos where nullables.Contains(foo.Value) select foo; ...and this: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); var myFoos = from foo in foos where values.Contains(foo.Value.Value) select foo; Both of these versions give me the results I expect, but they do not generate the SQL I want. It appears that they're generating full-table results and then doing the Contains() filtering in-memory (ie: in plain LINQ, without -to-SQL); there's no IN clause in the DataContext log. Is there a way to generate a SQL IN for Nullable types?

  • Referencing SQL Server 2008 R2 SMO from Visual Studio 2010

    - by user69508
    Hello. We read a number of things about referencing SQL Server SMO from Visual Studio but still don't have the definite answers we need. So, here it goes... A number of years ago we created a C# application using Visual Studio 2005 and SQL Server 2005. In that application, we added .NET references to a number of SQL Server SMO objects, and everything worked fine. Those references were: Microsoft.SqlServer.ConnectionInfo GAC 9.0.242.0 Microsoft.SqlServer.Smo GAC 9.0.242.0 Microsoft.SqlServer.SqlEnum GAC 9.0.242.0 We have now migrated to Visual Studio 2010 and SQL Server 2008 R2. However, when we try to reference those same SMO objects for SQL Server 2008 R2, they don't appear in the .NET references tab. We're wanting to reference the SQL Server 2008 R2 version of those same SMO assemblies for our upgraded C# application. On our development machines, we have SQL Server 2008 R2 Developer installed with all options, including the SDK such that the assemblies are found in C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies. So, my first questions are: Are we supposed to do file references to the SMO assemblies instead of .NET references in Visual Studio 2010 w/ SQL Server 2008 R2? Or, is there some problem with our development machines such that the SMO assemblies are not appearing in the .NET references tab? Next, our production machines will have SQL Server 2008 R2 Workgroup installed with the client tools option selected, thus providing those same SMO assemblies in C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies. So, the next questions are: When we release to production, are we supposed to redistribute the SMO assemblies with our application? Or, will our application work on the production servers without redistributing the SMO assemblies (since the client tools/SMO assemblies have been installed)? What else????? Thanks for the help!

  • sql 2008 sqldmo alternative

    - by alexdelpiero
    Hi! I previously was using sqldmo to automatically generate scripts from the databse. Now I upgraded to sql server 2008 and I don’t want to use this feature anymore since Microsoft will be dropping this feature off. Is there any other alternative I can use to connect to a server and generate scripts automatically from a database? Any answer is welcome. Thanks in advance. This is the procedure i was previously using: CREATE PROC GenerateSP ( @server varchar(30) = null, @uname varchar(30) = null, @pwd varchar(30) = null, @dbname varchar(30) = null, @filename varchar(200) = 'c:\script.sql' ) AS DECLARE @object int DECLARE @hr int DECLARE @return varchar(200) DECLARE @exec_str varchar(2000) DECLARE @spname sysname SET NOCOUNT ON -- Sets the server to the local server IF @server is NULL SELECT @server = @@servername -- Sets the database to the current database IF @dbname is NULL SELECT @dbname = db_name() -- Sets the username to the current user name IF @uname is NULL SELECT @uname = SYSTEM_USER -- Create an object that points to the SQL Server EXEC @hr = sp_OACreate 'SQLDMO.SQLServer', @object OUT IF @hr < 0 BEGIN PRINT 'error create SQLOLE.SQLServer' RETURN END -- Connect to the SQL Server IF @pwd is NULL BEGIN EXEC @hr = sp_OAMethod @object, 'Connect', NULL, @server, @uname IF @hr < 0 BEGIN PRINT 'error Connect' RETURN END END ELSE BEGIN EXEC @hr = sp_OAMethod @object, 'Connect', NULL, @server, @uname, @pwd IF @hr < 0 BEGIN PRINT 'error Connect' RETURN END END --Verify the connection EXEC @hr = sp_OAMethod @object, 'VerifyConnection', @return OUT IF @hr < 0 BEGIN PRINT 'error VerifyConnection' RETURN END SET @exec_str = 'DECLARE script_cursor CURSOR FOR SELECT name FROM ' + @dbname + '..sysobjects WHERE type = ''P'' ORDER BY Name' EXEC (@exec_str) OPEN script_cursor FETCH NEXT FROM script_cursor INTO @spname WHILE (@@fetch_status < -1) BEGIN SET @exec_str = 'Databases("'+ @dbname +'").StoredProcedures("'+RTRIM(UPPER(@spname))+'").Script(74077,"'+ @filename +'")' EXEC @hr = sp_OAMethod @object, @exec_str, @return OUT IF @hr < 0 BEGIN PRINT 'error Script' RETURN END FETCH NEXT FROM script_cursor INTO @spname END CLOSE script_cursor DEALLOCATE script_cursor -- Destroy the object EXEC @hr = sp_OADestroy @object IF @hr < 0 BEGIN PRINT 'error destroy object' RETURN END GO

  • Linq to SQL with INSTEAD OF Trigger and an Identity Column

    - by Bob Horn
    I need to use the clock on my SQL Server to write a time to one of my tables, so I thought I'd just use GETDATE(). The problem is that I'm getting an error because of my INSTEAD OF trigger. Is there a way to set one column to GETDATE() when another column is an identity column? This is the Linq-to-SQL: internal void LogProcessPoint(WorkflowCreated workflowCreated, int processCode) { ProcessLoggingRecord processLoggingRecord = new ProcessLoggingRecord() { ProcessCode = processCode, SubId = workflowCreated.SubId, EventTime = DateTime.Now // I don't care what this is. SQL Server will use GETDATE() instead. }; this.Database.Add<ProcessLoggingRecord>(processLoggingRecord); } This is the table. EventTime is what I want to have as GETDATE(). I don't want the column to be null. And here is the trigger: ALTER TRIGGER [Master].[ProcessLoggingEventTimeTrigger] ON [Master].[ProcessLogging] INSTEAD OF INSERT AS BEGIN SET NOCOUNT ON; SET IDENTITY_INSERT [Master].[ProcessLogging] ON; INSERT INTO ProcessLogging (ProcessLoggingId, ProcessCode, SubId, EventTime, LastModifiedUser) SELECT ProcessLoggingId, ProcessCode, SubId, GETDATE(), LastModifiedUser FROM inserted SET IDENTITY_INSERT [Master].[ProcessLogging] OFF; END Without getting into all of the variations I've tried, this last attempt produces this error: InvalidOperationException Member AutoSync failure. For members to be AutoSynced after insert, the type must either have an auto-generated identity, or a key that is not modified by the database after insert. I could remove EventTime from my entity, but I don't want to do that. If it was gone though, then it would be NULL during the INSERT and GETDATE() would be used. Is there a way that I can simply use GETDATE() on the EventTime column for INSERTs? Note: I do not want to use C#'s DateTime.Now for two reasons: 1. One of these inserts is generated by SQL Server itself (from another stored procedure) 2. Times can be different on different machines, and I'd like to know exactly how fast my processes are happening.

  • Back up a single table in SQL Server

    - by BuckWoody
    SQL Server doesn’t have an easy way to take a table backup, so I often use the bcp (Bulk Copy Program) to accomplish the same goal. I’ve mentioned this before, and someone told me when they tried it they couldn’t restore the table – ah the dangers of telling people half the information! I should have mentioned that you need to have a “format file” ready if the table does not exist at the destination. In my case I already had the table, in this person’s case they did not. The format file can be used to rebuild that table structure before the data is bcp’d in, and you can read more about it here: http://msdn.microsoft.com/en-us/library/ms191516.aspx There’s another way to back up a table, and that’s to create a Filegroup and place the table there. Then you can take a Filegroup backup to back up a single table. Of course, there are other methods of moving a single table’s data in an out, including SQL Server Integration Services and even the older Data Transformation Services, or simply by using hte SQLCMD or PowerShell utilities to run a query and just save the output to a file. In fact, these days I’m using a PowerShell script to build INSERT statements from that query. That could also easily be modified to create the table structure (or modify one if needed) quite easily.

  • MS SQL datetime precision problem

    - by Nailuj
    I have a situation where two persons might work on the same order (stored in an MS SQL database) from two different computers. To prevent data loss in the case where one would save his copy of the order first, and then a little later the second would save his copy and overwrite the first, I've added a check against the lastSaved field (datetime) before saving. The code looks roughly like this: private bool orderIsChangedByOtherUser(Order localOrderCopy) { // Look up fresh version of the order from the DB Order databaseOrder = orderService.GetByOrderId(localOrderCopy.Id); if (databaseOrder != null && databaseOrder.LastSaved > localOrderCopy.LastSaved) { return true; } else { return false; } } This works for most of the time, but I have found one small bug. If orderIsChangedByOtherUser returns false, the local copy will have its lastSaved updated to the current time and then be persisted to the database. The value of lastSaved in the local copy and the DB should now be the same. However, if orderIsChangedByOtherUser is run again, it sometimes returns true even though no other user has made changes to the DB. When debugging in Visual Studio, databaseOrder.LastSaved and localOrderCopy.LastSaved appear to have the same value, but when looking closer they some times differ by a few milliseconds. I found this article with a short notice on the millisecond precision for datetime in SQL: Another problem is that SQL Server stores DATETIME with a precision of 3.33 milliseconds (0. 00333 seconds). The solution I could think of for this problem, is to compare the two datetimes and consider them equal if they differ by less than say 10 milliseconds. My question to you is then: are there any better/safer ways to compare two datetime values in MS SQL to see if they are exactly the same?

  • Instead of trigger in SQL Server - looses SCOPE_IDENTITY?

    - by kastermester
    Hey StackOverflow, I am (once again) having some issues with some SQL. I have a table, on which I have created an INSTEAD OF trigger to enforce some buissness rules (rules not really important). This works as intended. My issue is, that now when inserting data into this table, SCOPE_IDENTITY() now returns a NULL value, rather than the actual inserted identity, my guess is that this is because it is now out of scope - but then how do I get this in scope? I am using SQL Server 2008. Per request, here's the SQL: Insert + Scope code INSERT INTO [dbo].[Payment]([DateFrom], [DateTo], [CustomerId], [AdminId]) VALUES ('2009-01-20', '2009-01-31', 6, 1) SELECT SCOPE_IDENTITY() Trigger: CREATE TRIGGER [dbo].[TR_Payments_Insert] ON [dbo].[Payment] INSTEAD OF INSERT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; IF NOT EXISTS(SELECT 1 FROM dbo.Payment p INNER JOIN Inserted i ON p.CustomerId = i.CustomerId WHERE (i.DateFrom >= p.DateFrom AND i.DateFrom <= p.DateTo) OR (i.DateTo >= p.DateFrom AND i.DateTo <= p.DateTo) ) AND NOT EXISTS (SELECT 1 FROM Inserted p INNER JOIN Inserted i ON p.CustomerId = i.CustomerId WHERE (i.DateFrom <> p.DateFrom AND i.DateTo <> p.DateTo) AND ((i.DateFrom >= p.DateFrom AND i.DateFrom <= p.DateTo) OR (i.DateTo >= p.DateFrom AND i.DateTo <= p.DateTo)) ) BEGIN INSERT INTO dbo.Payment (DateFrom, DateTo, CustomerId, AdminId) SELECT DateFrom, DateTo, CustomerId, AdminId FROM Inserted END ELSE BEGIN ROLLBACK TRANSACTION END END The code did work before the creation of this trigger, also I am using LINQ to SQL in C# and as far as I can see, I have no way of changing SCOPE_IDENTITY to @@IDENITY - is there really no way out of this one?

  • How to set minimum SQL Server resource allocation for a database?

    - by Jeff Widmer
    Over the past Christmas holiday week, when the website I work on was experiencing very low traffic, we saw several Request timed out exceptions (one on each day 12/26, 12/28, 12/29, and 12/30) on several pages that require user authentication. We rarely saw Request timed out exceptions prior to this very low traffic week. We believe the timeouts were due to the database that it uses being "spun down" on the SQL Server and taking longer to spin up when a request came in. There are 2 databases on the SQL Server (SQL Server 2005), one which is specifically for this application and the other for the public facing website and for authentication; so in the case where users were not logged into the application (which definitely could have been for several hours at a time over Christmas week) the application database probably received no requests. We think at this point SQL Server reallocated resources to the other database and then when a request came in, extra time was needed to spin up the application database and the timeout occurred. Is there a way to tell SQL Server to give a minimum amount of resources to a database at all times?

  • SQL Server lock/hang issue

    - by mattwoberts
    Hi, I'm using SQL Server 2008 on Windows Server 2008 R2, all sp'd up. I'm getting occasional issues with SQL Server hanging with the CPU usage on 100% on our live server. It seems all the wait time on SQL Sever when this happens is given to SOS_SCHEDULER_YIELD. Here is the Stored Proc that causes the hang. I've added the "WITH (NOLOCK)" in an attempt to fix what seems to be a locking issue. ALTER PROCEDURE [dbo].[MostPopularRead] AS BEGIN SET NOCOUNT ON; SELECT c.ForeignId , ct.ContentSource as ContentSource , sum(ch.HitCount * hw.Weight) as Popularity , (sum(ch.HitCount * hw.Weight) * 100) / @Total as Percent , @Total as TotalHits from ContentHit ch WITH (NOLOCK) join [Content] c WITH (NOLOCK) on ch.ContentId = c.ContentId join HitWeight hw WITH (NOLOCK) on ch.HitWeightId = hw.HitWeightId join ContentType ct WITH (NOLOCK) on c.ContentTypeId = ct.ContentTypeId where ch.CreatedDate between @Then and @Now group by c.ForeignId , ct.ContentSource order by sum(ch.HitCount * hw.HitWeightMultiplier) desc END The stored proc reads from the table "ContentHit", which is a table that tracks when content on the site is clicked (it gets hit quite frequently - anything from 4 to 20 hits a minute). So its pretty clear that this table is the source of the problem. There is a stored proc that is called to add hit tracks to the ContentHit table, its pretty trivial, it just builds up a string from the params passed in, which involves a few selects from some lookup tables, followed by the main insert: BEGIN TRAN insert into [ContentHit] (ContentId, HitCount, HitWeightId, ContentHitComment) values (@ContentId, isnull(@HitCount,1), isnull(@HitWeightId,1), @ContentHitComment) COMMIT TRAN The ContentHit table has a clustered index on its ID column, and I've added another index on CreatedDate since that is used in the select. When I profile the issue, I see the Stored proc executes for exactly 30 seconds, then the SQL timeout exception occurs. If it makes a difference the web application using it is ASP.NET, and I'm using Subsonic (3) to execute these stored procs. Can someone please advise how best I can solve this problem? I don't care about reading dirty data... Thanks

  • How do I login to SQL Server without having to use "Run as Administrator" when starting Management S

    - by MedicineMan
    When I start Management Studio, unless I use the "Run as Administrator" selection, I cannot login to my local SQL Server. Is this normal? I am a normal developer and don't believe I have a need for high security on my local machine. I'm running SQL Server 2008, Windows 7. The error I get is: Cannot connect to (local) Additional Information Login failed for user 'MYCOMPUTER\MyName'. (Microsoft SQL Server, Error: 18456)

  • How can you connect to a SQL Server not on your domain?

    - by scotty2012
    I have a test machine that's not allowed on our domain because we are testing corporately unsupported applications (SQL 2008 and Server 2008). I want to use management studio to connect to the SQL2008 server but can't get it working. I have authentication set to mixed-mode, I've checked 'allow remote connections to this server', but when I try to access it, I get the error A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53) Since it says the provider is Named Pipes, I enabled Named Pipes on the server, but still no dice. I've tried connecting to the system name, the IP, the system name\instance and IP\instance, all to no avail. Is what I'm trying to do not possible? Edit: Well, through some basic troubleshooting, I've found that I can't ping the server from my client computer, but I can ping the client computer from the server? They are both plugged into the same switch, and are sitting next to each other. The windows firewall on the server is turned on, is there some specific settings I need to enable? DAH! So it was the firewall blocking me. How can I enable the firewall and still connect?

  • Remote SQL server connection failure

    - by Sevki
    I am trying to connect to my MSSQL server 2008 web instance and im failing horribly... i get the error 26 and before you jump on me i have done these Check the spelling of the SQL Server instance name that is specified in the connection string. Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections over the TCP or named pipes protocols. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. Make sure that you have configured the firewall on the server instance of SQL Server to open ports for SQL Server and the SQL Server Browser port (UDP 1434). Make sure that the SQL Server Browser service is started on the server. in addition to theese i have disabled the firewall completely and tried other ports nothing works the same credentials work on the server but not on the client. this is the exact error message A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (.Net SqlClient Data Provider) Can anybody help?
