I found there are lots of advanced featured stored procedures in SQL Server which are not documented by the Books Online. I found them from googling. Here are some of them if you have others please share them with me.

sp_MSforeachtable can be used to loop through all the tables in your databases. Here are some common usages of this useful stored procedure
Display the size of all tables in a database
EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"
Display Number of Rows in all Tables in a database
EXEC sp_MSforeachtable 'SELECT ''?'', Count(*) as NumberOfRows FROM ?'
Rebuild all indexes of all tables in a database
EXEC sp_MSforeachtable @command1="print '?' DBCC DBREINDEX ('?', ' ', 80)"
GO
Note: DBCC DBREINDEX has been deprecated in SQL 2005. Microsoft says "This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use ALTER INDEX instead."
Disable all constraints of all tables in a database
USE YOURDBNAME
EXEC sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"
Disable all Triggers of all tables in a database
USE YOURDBNAME
EXEC sp_MSforeachtable 'ALTER TABLE ? DISABLE TRIGGER ALL'
Delete all data from all tables in your database
-- disable referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO
EXEC sp_MSForEachTable '
IF OBJECTPROPERTY(object_id(''?''), ''TableHasForeignRef'') = 1
DELETE FROM ?
else
TRUNCATE TABLE ?
'
GO
-- enable referential integrity again
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'
GO
To RESEED all table to 0, use this script
EXEC sp_MSForEachTable '
IF OBJECTPROPERTY(object_id(''?''), ''TableHasIdentity'') = 1
DBCC CHECKIDENT (''?'', RESEED, 0)
GO
guys share your knowledge at one place so lots of developers gain bani fits from this.
