• SQL Server Reducing storage space by moving rarely required columns to separate table while sharing Primary Key constraint

  Dear all, In my current database design, there is one table (PState) which has a Primary Key (int) and a few other fields. During development, a pattern started to arise; for certain rows in PState, I wanted to specify an additional set of columns (over 10 of them with quite large lengths) for each row in PState. However, as these additional columns would only be required in approximately 20% of the rows of PState, there would be plenty of NULL values in PState if I would make this table wider than necessary. So, I decided to create a separate table with those optional columns (PStateWFI). In order to attach these additional columns in PStateWFI to PState in the cases they were needed, I would obviously have to create a Foreign Key c ...Show All

• SQL Server SQL Express user permissions?

  I'm trying to build a web application using SQL2005 Express and Visual Studio Express.  It all works OK on the local machine, but gives an error "Login failed for user xxxx\ASPNET" when used remotely.  I can't find where I can set login permissions for SQLServer 2005 Expresss - can anyone help, please Thanks John This looks like a problem in the login control. The error reported probably has nothing to do with the actual error. The "login failed" error should always be logged to the errorlog file, if it did indeed happen. Probably the control is reporting incorrectly the error. Try contacting the VS team if this is a VS control. From what you have told me, there seems to be no problem with how ...Show All

• Visual Studio 2008 (Pre-release) It is too difficult to start a new WCF service

  I am starting to get really frustrated. I have been using the an old CTP of .net 3.0 and been developing fine. It is nice and quick and simple 1. file->new web site 2. choose C# WCF website 3. hit compile. and all the WSDL etc. is auto generated 4. tell my client to add a new service reference Now that i've installed on the latest September CTP there are a thousand steps 1. file->new web site 2. choose C# WCF website 3. hit compile. and nothing is setup. 4. read a few websites about how to enable WSDL. 5. Realise that you then have to setup some endpoints 6. realise that none of it works 7. post on MSDN Any help would be great. I was half way through a project but can't continue any further until i can actually create a new serv ...Show All

• Visual Studio Team System Server Restore

  I have a server that was infected with a virus and therefore had to reinstall windows. The machine, domain and service accounts are all the same between the two installations, but when I try to execute "tfsadminutil sid /change sbdweblocal sbdweblocal" it tells me "ERROR: Could not access database". The application pools for TFS are using SBDWEBLOCAL\TfsServices as their identity and I've verified that this account has access to the database by logging in as it and opening each table in the SQL Server Management studio. I'm pretty sure this is a SQL server security issue, but I'm not quite sure what to check next. thanks, Aaron I was able to find that Reporting Services were not setup corr ...Show All

That is, without detaching it from the server I can't access If you do think that you have access to the server wouldn't it be better to find out why you can not get the connection rather then just moving the problem to another server ...Show All
