  • Linq-to-SQL produces bad SQL?

    - by strager
    I am trying to run a Linq-to-SQL query, but when the query is evaluated, I get the following exception: System.Data.OleDb.OleDbException was unhandled Message=The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect.

  • SQL: Speed Improvement - Cluttered union query

This is a continuation question from my other question. The succession of these improvements has dropped the query down from ~32000ms to where it's at now ~1200ms - quite an improvement. I supect I can optimize by using UNION ALL in the subquery and of course the usual index optimizations, but I'm looking for the best SQL optimization. FYI this particular case is for PostgreSQL.

  • Why use INCLUDE in a SQL index

    - by StarLite
    I recently encountered an index in a database I maintain that was of the form: CREATE INDEX [IX_Foo] ON [Foo] ( Id ASC ) INCLUDE ( SubId ) In this particular case, the performance problem that I was encountering (a slow SELECT filtering on both Id and SubId) could be fixed by simply moving the SubId column into the index proper rather than as an included column. This got me thinking however that I don't understand the reasoning behind included columns at all, when generally, they could simply be a part of the index itself. Even if I don't particularly care about the items being in the index itself is there any downside to having column in the index rather than simply being included. After some research, I am aware that there are a number of restrictions on what can go into an indexed column (maximum width of the index, and some column types that can't be indexed like 'image'). In these cases I can see that you would be forced to include the column in the index page data. The only thing I can think of is that if there are updates on SubId, the row will not need to be relocated if the column is included (though the value in the index would need to be changed). Is there something else that I'm missing? I'm considering going through the other indexes in the database and shifting included columns in the index proper where possible. Would this be a mistake? I'm primarily interested in MS SQL Server, but information on other DB engines is welcome also.

  • Creating LINQ to SQL Data Models' Data Contexts with ASP.NET MVC

    - by Maxim Z.
    I'm just getting started with ASP.NET MVC, mostly by reading ScottGu's tutorial. To create my database connections, I followed the steps he outlined, which were to create a LINQ-to-SQL dbml model, add in the database tables through the Server Explorer, and finally to create a DataContext class. That last part is the part I'm stuck on. In this class, I'm trying to create methods that work around the exposed data. Following the example in the tutorial, I created this: using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MySite.Models { public partial class MyDataContext { public List<Post> GetPosts() { return Posts.ToList(); } public Post GetPostById(int id) { return Posts.Single(p => p.ID == id); } } } As you can see, I'm trying to use my Post data table. However, it doesn't recognize the "Posts" part of my code. What am I doing wrong? I have a feeling that my problem is related to my not adding the data tables correctly, but I'm not sure. Thanks in advance.

  • When connecting SAP Business One to SQL Server 2005, what is the

    - by Nick
    we have SAP Business One - Fourth Shift Edition running here at a small manufacturing company. The consulting company that has come in to do the installation/implementation uses the "sa" id/pass to initially connect to the database to get the list of companies. From then on, I have to assume that its the sa id/pass that is being used to connect the client software to the database. Is this appropriate? I dont know where this data is being stored... as an ODBC connection? directly in the registry somewhere? Is it secure? Would it be better to set the users network ID in the database security and then use the "trusted connection" setting instead? Or do most people create a separate login in the database for each user and use that in the client settings? seems like the easiest way would be to add the users network login to the sql server security so they can use the "trusted connection"... but then wouldn't that allow ANY software to connect to the database from that machine? So anyways: what are the best-practices for setting this up?

  • Replacement for deprecated SQL Server User Defined Type with a bound Rule and Default

    - by Adam Jones
    We have a User Defined Data Type of YesNo which has an which is an alias for char(1). The type has a bound Rule (must be Y or N) and a Default (N). The aim of this is that when any of the development team create a new field of type YesNo the rule and default are automatically bound to the new column. Rules and Defaults have been deprecated and won't be available in the next a future version of SQL Server, is there another way to achieve the same functionality? I should add that I'm aware that I could use CHECK and DEFAULT constraints to replicate the functionality of the bound Rule and Defalut objects, however these would have to be applied at each usage of the type, rather than getting the functionality 'for free' by using a UDT which has a bound Rule and Default. The post relates to a database that backs an existing application, rather than a new development, so I'm aware that our use of UDT's is less than optimal. I suspect the answer to the question is 'No', however normally when features are deprecated there's usually an alternative syntax that can be used as a drop in replacement so I wanted to pose the question in-case someone knew of an alternative.

  • SQL select row into a string variable without knowing columns

    - by Brandi
    Hello, I am new to writing SQL and would greatly appreciate help on this problem. :) I am trying to select an entire row into a string, preferably separated by a space or a comma. I would like to accomplish this in a generic way, without having to know specifics about the columns in the tables. What I would love to do is this: DECLARE @MyStringVar NVARCHAR(MAX) = '' @MyStringVar = SELECT * FROM MyTable WHERE ID = @ID AS STRING But what I ended up doing was this: DECLARE @MyStringVar = '' DECLARE @SecificField1 INT DECLARE @SpecificField2 NVARCHAR(255) DECLARE @SpecificField3 NVARCHAR(1000) ... SELECT @SpecificField1 = Field1, @SpecificField2 = Field2, @SpecificField3 = Field3 FROM MyTable WHERE ID = @ID SELECT @StringBuilder = @StringBuilder + CONVERT(nvarchar(10), @Field1) + ' ' + @Field2 + ' ' + @Field3 Yuck. :( I have seen some people post stuff about the COALESCE function, but again, I haven't seen anyone use it without specific column names. Also, I was thinking, perhaps there is a way to use the column names dynamically getting them by: SELECT [COLUMN_NAME] FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'MyTable' It really doesn't seem like this should be so complicated. :( What I did works for now, but thanks ahead of time to anyone who can point me to a better solution. :) EDIT: Got it fixed, thanks to everyone who answered. :)

  • HyperV - low CPU usage

    - by Klark
    I am very new to HyperV and virtual machine philosophy in general, so please expect more or less nooby questions :) I have a server that is only used as a host for virtual machines. OS is windows server 2008 R2 and it is running on 16 CPU and 48 GBs of RAM. On aforementioned server there are 8 VMs, each having 4 CPUs and 4 GBs of RAM. On those VMs we are running some CPU intensive tasks. Each machine has nearly 100% cpu usage. After I noticed slow performance I went to the host machine and started playing with process explorer. It turned out that cpu usage is very low. Also I/O is very low, and of course, memory consumption is high, which is expected. Of course, I don't expect that those 4 virtual cores dedicated to a VM work as fast as real, hardware 4 cores, but still I expected a higher consumption of real hardware. Is this sort of behaviour normal? I see that the most of CPU usage on host machine are marked as interrupts (which I guess is normal) and all those interrupts are passed to only one core (which is strange). Are there out of box optimization that I could perform to finally use all that processing power that is under the hood. My knowledge of virtualization technology is near to embarrassing, so I would be grateful for any links that could enlightened me :) Thanks.

  • Winamp playing sound but no video

    - by Greg Sansom
    I am having problems playing video in Winamp (the movie I am trying to play is an AVI - not sure if other formats work). I have installed the K-Lite Codec Pack, and the video does work in Winamp Classic. I can also play the video in Winamp on another machine (although I can't remember the exact configuration details of that machine - and I don't think they're relevant). There are a few symptoms: The content of the Video view is either empty, transparent, or displays rendering from other programs. Opening the Visualization view shows the following error: MILKDROP ERROR DirectX initialization failed (GetDeviceCaps). This means that no valid 3D-accelerated display adapter could be found on your computer. If you know this is not the case, it is possible that your graphics subsystem is unstable; please try rebooting your computer and then try to run the plugin again. Otherwise, please install a 3D-accelerated display adapter. Trying to open streams via the SHOUTCast TV plugin shows Error opening video output, and the video does not open. Opening the file with WMC causes the following error (although the movie still plays): Error creating DX9 allocation presenter CreateDevice failed D3DERR_NOTAVAILABLE There are no warnings displayed in Device Manager, although the display adapter is the standard Windows one. Running DxDiag shows no problems (codec for Video listed as XviD 1.1.2 Final). GSpot reports that codecs are installed. System specs: - Windows Server 2008 r2 Standard 64-bit, with latest updates; - .NET 3.5.1 installed; - Winamp v5.6.01 (latest version); - DirectX 11 (Latest version); - K-Lite Codec Pack 7.0.0 (Full); - Machine is HP DC7600 - full specs here. Please comment if there is any more information which will help to diagnose the problem.

  • SQL, MVC, Entity Framework

    - by Anthony
    Hi Im using the above technologies and have ran into what I presume is a design issue I have made. I have an Artwork table in my DB and have been able to add art (I now think of these as Digital Products) to a shopping cart + CartLine table fine. The system I have that adds art to galleries and user accounts etc works fine. Now the client wants to sell T-shirts, Mugs and Pens etc, 'HardwareProducts' so I have created a 'HardwareProducts' table. Now I have two different product types in two tables. I use GUID's as the PK's in both the HardwareProducts table and Artwork table. When a customer adds an item to their cart I store the GUID in the ProductID column in the CartItems table. The issue is the database will not know which table to reference when I bring the LineItem object up through my ORM to the front end. In OOP I can see how you would have a base class of Product, and then a DigitalProduct class and HardwareProduct class drived from it, but how do you model this in SQL Server and the Entity Framework please, or is there another way?

  • What is the scope of TRANSACTION in Sql server

    - by Shantanu Gupta
    I was creating a stored procedure and i got stuck in the writing methodology of me and my collegue. I am using SQL Server 2005 I was writing Stored procedure like this BEGIN TRAN BEGIN TRY INSERT INTO Tags.tblTopic (Topic, TopicCode, Description) VALUES(@Topic, @TopicCode, @Description) INSERT INTO Tags.tblSubjectTopic (SubjectId, TopicId) VALUES(@SubjectId, @@IDENTITY) COMMIT TRAN END TRY BEGIN CATCH DECLARE @Error VARCHAR(1000) SET @Error= 'ERROR NO : '+ERROR_NUMBER() + ', LINE NO : '+ ERROR_LINE() + ', ERROR MESSAGE : '+ERROR_MESSAGE() PRINT @Error ROLLBACK TRAN END CATCH And my collegue was writing it like the below one BEGIN TRY BEGIN TRAN INSERT INTO Tags.tblTopic (Topic, TopicCode, Description) VALUES(@Topic, @TopicCode, @Description) INSERT INTO Tags.tblSubjectTopic (SubjectId, TopicId) VALUES(@SubjectId, @@IDENTITY) COMMIT TRAN END TRY BEGIN CATCH DECLARE @Error VARCHAR(1000) SET @Error= 'ERROR NO : '+ERROR_NUMBER() + ', LINE NO : '+ ERROR_LINE() + ', ERROR MESSAGE : '+ERROR_MESSAGE() PRINT @Error ROLLBACK TRAN END CATCH Here the only difference that you will find is the position of writing Begin TRAN. According to me the methodology of my collegue should not work when an exception occurs i.e. Rollback should not get executed because TRAN does'nt have scope. But when i tried to run both the code, both was working in the same way. I am confused to know how does TRANSACTION works. Is it scope free or what ?

  • Changing the indexing on existing table in SQL Server 2000

    - by Raj
    Guys, Here is the scenario: SQL Server 2000 (8.0.2055) Table currently has 478 million rows of data. The Primary Key column is an INT with IDENTITY. There is an Unique Constraint imposed on two other columns with a Non-Clustered Index. This is a vendor application and we are only responsible for maintaining the DB. Now the vendor has recommended doing the following "to improve performance" Drop the PK and Clustered Index Drop the non-clustered index on the two columns with the UNIQUE CONSTRAINT Recreate the PK, with a NON-CLUSTERED index Create a CLUSTERED index on the two columns with the UNIQUE CONSTRAINT I am not convinced that this is the right thing to do. I have a number of concerns. By dropping the PK and indexes, you will be creating a heap with 478 million rows of data. Then creating a CLUSTERED INDEX on two columns would be a really mammoth task. Would creating another table with the same structure and new indexing scheme and then copying the data over, dropping the old table and renaming the new one be a better approach? I am also not sure how the stored procs will react. Will they continue using the cached execution plan, considering that they are not being explicitly recompiled. I am simply not able to understand what kind of "performance improvement" this change will provide. I think that this will actually have the reverse effect. All thoughts welcome. Thanks in advance, Raj

  • How can I add a VS 2010 .Net 4.0 build agent to TFS 2008

    - by Mark Arnott
    My company has two development teams using TFS 2008. My team would like to migrate our .Net 3.5 app to the .Net 4.0 framework, but the company is not ready to upgrade TFS to TFS 2010. Can we still use TFS 2008's team build system but with a Visual Studio 2010 solution/project structure that targets the .Net 4.0 framework? I am thinking we would need to add a new build agent to TFS 2008 that would have VS 2010 installed. But I am not finding any information on how to do this. Is this possible? Are there any articles explaining how to do this?

  • What noncluster index would be better to create on SQL Server?

    - by Junior Mayhé
    Here I am studying nonclustered indexes on SQL Server Management Studio. I've created a table with more than 1 million records. This table has a primary key. SELECT CustomerName FROM Customers Which leads the execution plan to show me: I/O cost = 3.45646 Operator cost = 4.57715 For the first attempt to improve performance, I've created a nonclustered index for this table: CREATE NONCLUSTERED INDEX [IX_CustomerID_CustomerName] ON [dbo].[Customers] ( [CustomerId] ASC, [CustomerName] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO With this first try, I've executed the select statement and the execution plan shows me: I/O cost = 2.79942 Operator cost = 3.92001 Now the second try, I've deleted this nonclustered index in order to create a new one. CREATE NONCLUSTERED INDEX [IX_CategoryName] ON [dbo].[Categories] ( [CategoryId] ASC ) INCLUDE ( [CategoryName]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO With this second try, I've executed the select statement and the execution plan shows me the same result: I/O cost = 2.79942 Operator cost = 3.92001 Am I doing something wrong or this is expected? Shall I use the first nonclustered index with two fields, or the second nonclustered with one field (CategoryID) including the second field (CategoryName)?

  • MS SQL Server 2000 tables

    - by klork
    We currently have an MS SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: 1) Does anyone have any experience with a MS SQL Server (2000/2005) installation with millions of tables? 2) What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. 3) What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

  • Changing the Start Menu Power Button - Setting does not work: only (Shut down) is available

    - by Martin
    This is the second time I try to change this setting on a Vista based OS and I can't get it to work again. OS: Windows Server 2002 SP2 (not R2) = Microsoft Windows [Version 6.0.6002] = Vista When I go to: Power Options - Change Plan Settings - Change advanced power settings - Power buttons and lid - Start menu power button - Setting: the available combo box will only show the option Shut down. No other options are available. This server is part of a domain and has not been set up by me. I have not yet talked with the domain admin, but as far as I could tell from googling, only Win7 has group policy options for the start menu. (And yes, OC I will talk to the domain admin to see if he has any clue - which I doubt.) (Edit: I have now talked to our domain admin, and he's got no clue either.) I'm responsible for this server and a local administrator but not a domain administrator. I switched off User Account Control (UAC) yesterday without problems. Since I always log into this machine via RDP and this being a server, the natural choice would be the option (Log out) and not (Shut down). What can I do to fix it or to find out why it cannot be changed? Thanks!

  • In SQL can I return a tables with a varying number of columns

    - by Matt
    I have a somewhat more complicated scenario, but I think it should be possible. I have a large SPROC whose result is a set of characteristics for a set of persons. So the Table would look something like this: Property | Client1 Client 2 Client3 ----------------------------------------------------------- Sex | M F M Age | 67 56 67 Income | Low Mid Low It's built using cursors, iterating over different datasets. The problem I am facing is that there is a varying number of Clients and Properties, so an equally valid result over different input sets might be: Property | Client1 Client 2 ------------------------------------------- Sex | M F Age | 67 56 Weight | 122 122 The different number of properties is easy, those are just extra rows. My problem is that I need to declare a temporary table with a varying number of columns. There could be 2 clients or 100. Every client in guaranteed to have every property ultimately listed. What SQL structure would statisfy this and how can I declare it and insert things into it? I can't just flip the columns and rows either because there is a variable number of each.

  • Access DB with SQL Server Back End

    - by uyuni99
    I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue.
