• Delete data from tables

EXEC sp_MSforeachtable @command1='delete from ?', @whereand=' and o.name like ''tbcip%'''

• Disable/enable constraints

-- DISABLE
EXEC sp_MSforeachtable @command1='ALTER TABLE ? NOCHECK CONSTRAINT ALL' ,@whereand=' and o.name like ''tbcip%'''
-- ENABLE
EXEC sp_MSforeachtable @command1='print ''?''', @command2='ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all', @whereand=' and o.name like ''tbcip%'' '

• Restore database

USE master;
GO
