Hi,

Those are ways to do the same :

http://blogs.msdn.com/b/martijnh/archive/2010/07/15/sql-server-how-to-quickly-retrieve-accurate-row-count-for-table.aspx[^]

For quick ref Use this :

SQL

SELECT SUM (row_count)
FROM sys.dm_db_partition_stats
WHERE object_id=OBJECT_ID('[Table Name]')
AND (index_id=0 or index_id=1);

Enjoy :)
