How to truncate all tables sql server?

Following script truncates all the tables in SQL Server:

[sql]

DECLARE @tablename AS VARCHAR (1000)

DECLARE @sql AS VARCHAR (1000)

IF OBJECT_ID(‘tempdb.dbo.#tables’) IS NOT NULL
DROP TABLE #tables

SELECT *
INTO #tables
FROM sys.tables

WHILE EXISTS (SELECT *
FROM #tables)
BEGIN
SELECT @tablename = name
FROM #tables
SELECT @sql = ‘truncate table ‘ + @tablename;
PRINT @sql
EXECUTE (@sql)
DELETE #tables
WHERE name = @tablename;
END
[/sql]

Works if the tables do not have foriegn key constrains or schema binding relations with other tables/objects in the database.
