  • GetOleDbSchemaTable Foreign Keys on Sql Server 2005

    - by haxelit
    I'm trying to get the Foreign Keys for a table in my SQL Server 2005 database. I'm using the GetOleDbSchemaTable function right now: DataTable schemaTable = connection.GetOleDbSchemaTable( OleDbSchemaGuid.Foreign_Keys, new object[] { null, null, null, "TABLE" }); This pulls back the right foreign keys, the only problem is that the UpdateRule and DeleteRule are set to "No Action". If I browse to the same table in SSMS I can see that my DeleteRule is "Set NULL". Does the GetOleDbSchemaTable function not return the proper foreign key rules ? Has any one else ran into this problem ?

  • 'Out of Memory exception' in sql server 2005 xml column

    - by Raghuraman
    Hi All, I am devloping a windows forms application and am using sql server 2005 database as my backend. I am having an xml column in my database. I am using ultrawingrid control in my application.I obtain the xml of the dataset which is bound to my ultrawingrid control and pass that as a parameter value to the stored procedure where am inserting this value into the xml column which I specified. The columns in my grid are dynamic and hence there can be any no of columns in my grid. I got 'out of memory' exception in the dataset.GetXml() statement since there were more no of columns I believe.So, what I did is that I used dataset.WriteXml() method and stored all the xml contents into an xml file, loaded the xml file into the XmlDocument object and then passed the xmlnodereader as the value to the stored procedure parameter.Now, while executing the stored procedure am getting the same 'out of memory' exception. How could I resolve this issue?

  • sql server 2005 replication article conflict

    - by Daniel
    Hi all, I have a sql server 2005 database that I want to setup replication for. The problem is that the database has two schemas both of which have a table with the same name in it. For some reason even though the tables are in different schemas the replication creation fails when done through management studio due to conflicting article names (i assume its trying to create the same name for both tables in the different schemas). Is there any workaround for doing this in the studio, I can probably write a script or program to do this but just for this one thign is a bit annoying and it probably wont be allowed to run in production. Perhaps there is a hot fix or something I'm not aware about? Cheers,

  • alias not working on sql server 2008 r2

    - by Saba
    I have several servers with SQL Server 2008 R2 instances on them, and alias doesn't work on any of them. Clients connect to these servers using TCP/IP without any problem, telnet works on IP/Port I use for my alias, the firewall exceptions are created, basically everything works fine, except when I create an alias, I can not connect through it to my server using either TCP/IP or named pipes (local or one of other servers). I've installed latest cumulative updates, which updates native client too (which I think is the source of problem) and I still have the problem. The stranger part is, if I create an alias on a server with sql server 2005 (native client 9), I can connect to my 2008 r2 instances. Any suggestions?

  • Proper chart scaling in Reporting Services 2005

    - by lastas
    I'm developing a simple bar-chart in Reporting Services 2005 with a stored procedure as data-source. The values in this graph can be both positive and negative, and can span a very big range, and hence I cannot specify any non-dynamic scale that will work for all scenarios. The problem I'm facing is that the automatic scaling pretty much sucks. I get no line to show where the zero-point is, and the y-scale labels are from top to bottom: 8818 -191181 -391181 etc etc... So my question is, what is the best approach to make the scale more adapted to human reading? Is there any guide out there? Does reporting services 2008 handle this better? Also, moving away from Reporting Services is not really an option. I realize how to put values and expression in the max, min, and the gridline interval fields, although its more of a question what expressions I should put there.

  • Should I switch my server to Ubuntu Server from Windows Server 2003

    - by user22162
    I have a server thats primarily used for SRCDS, I host a few Team Fortress 2 servers on it and I would much prefer a ssh-like (more so the no-gui part) for something like this, mostly because I can't navigate with my phone on VNC very well and also because there really is no need for a gui in this situation. I sort of want to make the switch but I am unsure, because my server 2003 is very fast and If I do need to reboot, it can reboot in under 30 seconds to desktop. Should I switch?

  • Logging in as the same user multiple times in Remote Desktop Windows Server 2008

    - by Little_Johnn
    Quick question: I have a situation where I need to let multiple people on different PCs log into one server 2008 machine as administrator simultaneously over remote desktop. I have the CALs for it, it's just not set up correctly. When one user tries to log in, it boots the other out. What I need is to present to them a different session, just each as logged in as admin. Sorry for the slightly rambling post, I'm new here. Thanks!

  • Cannot log in to the desktop on ubuntu 11.10?

    - by Jichao
    The problem is, I could log in under the terminal, i could ifup eth0, i could do anything I want in the terminal, but if I use ctrl+alt+f7 goto the gnome login screen, after I input the correct password, the system just send me back to same login screen again. I have created a new user, but it didn't work. I have change all the files under ~/ to jichao:jichao(which is my username) with chown -hR jichao:jichao /home/jichao, but it didn't work too. I searched the internet, somebody said I should see the logs under /var/log/gdm, but there is not a /var/log/gdm directory in my box.

  • Developing for 2005 using VS2008!

    - by Vincent Grondin
    I joined a fairly large project recently and it has a particularity… Once finished, everything has to be sent to the client under VS2005 using VB.Net and can target either framework 2.0 or 3.0… A long time ago, the decision to use VS2008 and to target framework 3.0 was taken but people knew they would need to establish a few rules to ensure that each dev would use VS2008 as if it was VS2005… Why is that so? Well simply because the compiler in VS2005 is different from the compiler inside VS2008…  I thought it might be a good idea to note the things that you cannot use in VS2008 if you plan on going back to VS2005. Who knows, this might save someone the headache of going over all their code to fix errors… -        Do not use LinQ keywords (from, in, select, orderby…).   -        Do not use LinQ standard operators under the form of extension methods.   -        Do not use type inference (in VB.Net you can switch it OFF in each project properties). o   This means you cannot use XML Literals.   -        Do not use nullable types under the following declarative form:    Dim myInt as Integer? But using:   Dim myInt as Nullable(Of Integer)     is perfectly fine.   -        Do not test nullable types with     Is Nothing    use    myInt.HasValue     instead.   -        Do not use Lambda expressions (there is no Lambda statements in VB9) so you cannot use the keyword “Function”.   -        Pay attention not to use relaxed delegates because this one is easy to miss in VS2008   -        Do not use Object Initializers   -        Do not use the “ternary If operator” … not the IIf method but this one     If(confition, truepart, falsepart).   As a side note, I talked about not using LinQ keyword nor the extension methods but, this doesn’t mean not to use LinQ in this scenario. LinQ is perfectly accessible from inside VS2005. All you need to do is reference System.Core, use namespace System.Linq and use class “Enumerable” as a helper class… This is one of the many classes containing various methods that VS2008 sees as extensions. The trick is you can use them too! Simply remember that the first parameter of the method is the object you want to query on and then pass in the other parameters needed… That’s pretty much all I see but I could have missed a few… If you know other things that are specific to the VS2008 compiler and which do not work under VS2005, feel free to leave a comment and I’ll modify my list accordingly (and notify our team here…) ! Happy coding all!

Same thing, RES doesn't add up to ~350mb. Why? Am I misunderstanding their meaning? Thanks

  • Database Snapshot in Sql Server 2005

    A database snapshot is a read-only, static view of a database (called the source database). Each database snapshot is transactionally consistent with the source database at the moment of the snapshot's creation. When you create a database snapshot, the source database will typically have open transactions. Before the snapshot becomes available, the open transactions are rolled back to make the database snapshot transactionally consistent.

  • SQL to select random mix of rows fairly [migrated]

    - by Matt Sieker
    Here's my problem: I have a set of tables in a database populated with data from a client that contains product information. In addition to the basic product information, there is also information about the manufacturer, and categories for those products (a product can be in one or more categories). These categories are then referred to as "Product Categories", and which stores these products are available at. These tables are updated once a week from a feed from the customer. Since for our purposes, some of the product categories are the same, or closely related for our purposes, there is another level of categories called "General Categories", a general category can have one or more product categories. For the scope of these tables, here's some rough numbers: Data Tables: Products: 475,000 Manufacturers: 1300 Stores: 150 General Categories: 245 Product Categories: 500 Mapping Tables: Product Category -> Product: 655,000 Stores -> Products: 50,000,000 Now, for the actual problem: As part of our software, we need to select n random products, given a store and a general category. However, we also need to ensure a good mix of manufacturers, as in some categories, a single manufacturer dominates the results, and selecting rows at random causes the results to strongly favor that manufacturer. The solution that is currently in place, works for most cases, involves selecting all of the rows that match the store and category criteria, partition them on manufacturer, and include their row number from within their partition, then select from that where the row number for that manufacturer is less than n, and use ROWCOUNT to clamp the total rows returned to n. This query looks something like this: SET ROWCOUNT 6 select p.Id, GeneralCategory_Id, Product_Id, ISNULL(m.DisplayName, m.Name) AS Vendor, MSRP, MemberPrice, FamilyImageName from (select p.Id, gc.Id GeneralCategory_Id, p.Id Product_Id, ctp.Store_id, Manufacturer_id, ROW_NUMBER() OVER (PARTITION BY Manufacturer_id ORDER BY NEWID()) AS 'VendorOrder', MSRP, MemberPrice, FamilyImageName from GeneralCategory gc inner join GeneralCategoriesToProductCategories gctpc ON gc.Id=gctpc.GeneralCategory_Id inner join ProductCategoryToProduct pctp on gctpc.ProductCategory_Id = pctp.ProductCategory_Id inner join Product p on p.Id = pctp.Product_Id inner join StoreToProduct ctp on p.Id = ctp.Product_id where gc.Id = @GeneralCategory and ctp.Store_id=@StoreId and p.Active=1 and p.MemberPrice >0) p inner join Manufacturer m on m.Id = p.Manufacturer_id where VendorOrder <=6 order by NEWID() SET ROWCOUNT 0 (I've tried to somewhat format it to make it cleaner, but I don't think it really helps) Running this query with an execution plan shows that for the majority of these tables, it's doing a Clustered Index Seek. There are two operations that take up roughly 90% of the time: Index Seek (Nonclustered) on StoreToProduct: 17%. This table just contains the key of the store, and the key of the product. It seems that NHibernate decided not to make a composite key when making this table, but I'm not concerned about this at this point, as compared to the other seek... Clustered Index Seek on Product: 69%. I really have no clue how I could make this one more performant. On categories without a lot of products, performance is acceptable (<50ms), however larger categories can take a few hundred ms, with the largest category taking 3s (which has about 170k products). It seems I have two ways to go from this point: Somehow optimize the existing query and table indices to lower the query time. As almost every expensive operation is already a clustered index scan, I don't know what could be done there. The inner query could be tuned to not return all of the possible rows for that category, but I am unsure how to do this, and maintain the requirements (random products, with a good mix of manufacturers) Denormalize this data for the purpose of this query when doing the once a week import. However, I am unsure how to do this and maintain the requirements. Does anyone have any input on either of these items?

  • The new SSIS in SQL2005/SQL2008 are oversized

    - by Ice
    I studied the new MERGE Statement and there is a nice example for importing a flatfile. INSERT <Table> SELECT * FROM OPENROWSET BULK <Import-Flat-File>, <Format-File>... seems to be a good replacment for such a simple job and avoids to build a SSIS-Package. EXEC XP_CMDSHELL bcp <Table or View> out <Flat-File> ... is almost simpler than building an SSIS, isn't it? (I know that the MERGE-Statement doesn't run on a SQL2005)

  • Sync LINQ-to-SQL DBML schema with SQL Server database

    - by Maxim Z.
    After creating a SQL Server 2008 database, I made a Linq-to-SQL schema in Visual Studio. Next, in the .dbml visual editor (in Visual Studio), I added PK-to-FK and PK-to-PK associations to the schema. How do I copy those associations that I created in Visual Studio over to the database? In other words, how do I sync with the DB?

  • SQL Agent Command Line Not Saved

    - by Greg
    I have a SSIS package I am trying to schedule. I create a new job under SQL Server Agent. On the Command line tab of the jobstep, I choose "Edit the command-line manually". The changes are retained as I switch from tab to tab within the job step but whenever I exit and save the job, the changes are lost. Any ideas what's going on? I'm on SQL Server 2008.

  • How To Automatically Script SQL Server: 'Generate Scripts' for SQL Database

    - by skimania
    I want to run scheduled nightly exports of my database code into my SVN source. It's easy to schedule automated check-in's into svn from a folder, but scheduling the export from SQL in SQL Management Studio is Right click target database, choose Tasks Generate Scripts. Follow the wizard and presto you've got scripts in a folder. Is it possible to extract a single script that the wizard generates, and stuff that into a stored proc which I can run nightly? Ideas?
