• SQL Server Update fields on n-side of 1:n-relation

  I have some tables with 1:n-relations. Now I want to update the n-side of the relation. Whatever i do the result is always: Subquery returned more than 1 value. This is not permitted ... Both number and internalNumber are unique in table k, which is the 1-side of the relation. Ab is one of the n-side tables. UPDATE Ab SET knr = (select k.internalNumber from Kunden as k where kNumber=k.number) In my opinion there should be one kNumber at a time and for each kNumber exists exactly 1 record in k. The following gives the same result: UPDATE Ab SET knr = k.internalNumber from Kunden as k w ...Show All

• SQL Server Unable to open MSDB node

  I'm sure there is a simple answer to this but it eludes me at the moment. I’m using the Developer Edition of SQL Server 2005. The MSDB node under Integration Services->Stored Packages refuses to open. It always fails with a login timeout message and that the connection was actively refused. I’ve run the SQL Server Surface Area Configuration tool and allowed remote and local access, even though it’s all installed on the local machine. This didn’t help. The next thing I did was to turn off all my firewalls and internet access control software and it’s still not working. ...Show All
