Getting Table Row Counts in Sql 2005

Tagged Under :

I came across a nice tip while reading this article. If you want to get the number of rows in a table , you would normally do a select count(*) from tbl query, which does a table scan and can be a little time consuming query if the table has millions of rows.

This little query gives you all the counts for every table in your database, pretty quickly and instantly.

-- Shows all user tables and row counts for the current database
-- Remove is_ms_shipped = 0 check to include system objects
-- i.index_id < 2 indicates clustered index (1) or hash table (0)
SELECT o.name,
 ddps.row_count
FROM sys.indexes AS i
 INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID
 INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID
 AND i.index_id = ddps.index_id
WHERE i.index_id < 2
 AND o.is_ms_shipped = 0
ORDER BY o.NAME
