Relational database clean

Sometimes when developing you want to start over with a clean database. But if you have relational integrity, and using the Identity feature in SQL server, it could be a bit tricky.

However, this does it for you:
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'

EXEC sp_MSForEachTable 'DELETE FROM ?'

EXEC sp_MSForEachTable 'DBCC CHECKIDENT (''?'', RESEED, 1)'

EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
