When I try to Create a Database Diagram it sends me an Error message like this:
Server Name: TIC\SQLEXPRESS Error Number: 207 Severity: 16 State: 1 Procedure: sp_upgraddiagrams Line Number: 55
Invalid column name 'uvalue'. Invalid column name 'uvalue'. Could not find stored procedure 'dbo.sp_upgraddiagrams'. Object is invalid. Extended properties are not permitted on 'dbo.sysdiagrams', or the object does not exist. Object is invalid. Extended properties are not permitted on 'dbo.sp_upgraddiagrams', or the object does not exist. (.Net SqlClient Data Provider)
How can I find that Stored Procedure 'dbo.sp_upgraddiagrams'? Why doesn't it work OK?
