Not really SharePoint related but something that really saved my bacon today!
If you are using an identity column for a number in SQL Server and need to change the current value – e.g.start the next identity seed at 500 rather you can use the following commands:
To check what the current identity value is:
DBCC CHECKIDENT (‘tablename’, NORESEED)
To set the valueof the next ID/Identity value, use this command (where value is the number you want):
DBCC CHECKIDENT (‘tablename’, RESEED, ‘value’)
Hope this helps some people.
