truncate all tables sql server 2008

How to truncate all tables sql server?

Following script truncates all the tables in SQL Server:

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

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