T-SQL – Find Number of Rows of Database(s) tables Using Undocumented Procedure – sp_MSforeachdb and sp_MSforeachtable

Added few more examples

Prashanth Jayaram

On Technet forum, Op was looking for a way to get table cardinality for all databases in an instance.  There are many ways to get the result. This post gives you an idea and SQL in which undocumented SP’s being called  “sp_MSforeachdb and sp_MSforeachtable”.

The above undocumented SP’s  iterate through each database and each table of a SQL instance

Download SQL :- UndocumentSPToGetNoOfRowsAllDatabases


CREATE TABLE  #TableRowCounts  ([databaseNAme] Varchar(100),[TableName] VARCHAR(128), [RowCount] INT) ;

EXEC sp_MSforeachdb
@command1 = 'IF not exists(select 1 where ''?'' in (''master'',''model'',''msdb'',''tempdb''))
INSERT INTO #TableRowCounts ([databaseNAme],[TableName], [RowCount])
EXEC [?].dbo.sp_MSforeachtable @command1 = ''SELECT ''''?'''',''''&'''',count(1) FROM &'',@replacechar = ''&'''

SELECT * FROM #TableRowCounts
DROP TABLE #TableRowCounts	

Note:-The above query is expensive. Please use at your risk



The use of IF and Like clause with sp_MSforeachtable

EXEC [sp_MSforeachtable] @command1=N'
IF (N''?'' =''[dbo].[log]'')
 PRINT N''?''
 SELECT COUNT(*) from ? 

EXEC [sp_MSforeachtable] @command1=N' IF (N''?'' LIKE N''%Resource%]'') BEGIN PRINT N''?'' SELECT ''?'' TABLENAME,COUNT(*)…
