whats the syntax to run sp_MSforeachdb against all databases that will inlude
database name In the output for:
SELECT Count(*) Count_in_TableName FROM dbo.TableName
or
select Count_in_TableName=(SELECT Count(*) FROM dbo.TableName)
so it looks like this...
Server NameDatabase NameCount_in_TableName
server1 db1 6
server2 db2 3
server3 db3 9

Do a loop or a cursor, construct a SQL statement for each database, and execute separately.:cool:

thank you
i know about this one...however
do you have an idea for specifically sp_foreachdb?

IF OBJECT_ID('tempdb.dbo.#row_counts') IS NOT NULL
DROP TABLE #row_counts
CREATE TABLE #row_counts (
db_name nvarchar(128) NOT NULL,
table_name nvarchar(128) NOT NULL,
row_count int NULL
)
EXEC sp_MSforeachdb '
IF ''?'' IN (''master'', ''model'', ''msdb'', ''tempdb'')
RETURN
USE [?]
EXEC sp_MSforeachtable @replacechar = ''!'', @command1 = ''
INSERT INTO #row_counts ( db_name, table_name, row_count )
SELECT ''''?'''' AS db_name, ''''!'''' AS table_name, COUNT(*) FROM !''
'
SELECT *
FROM #row_counts
ORDER BY
db_name, table_name

looks good, thank you!!!
so there is no way to use just something like
sp_foreachdb ' db_name() + select count(*) fro table' ??
i know it's the wrong syntax....just for you to have an idea what im looking
🙂 🙂

this query would be an order of magnitude faster (at least!) for getting row counts per table.
something like this is what you'd wnat to wrap with sp_msForEachdb:
SELECT o.name AS ObjectName,
ps.row_count AS TheCount
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 ps
ON i.OBJECT_ID = ps.OBJECT_ID
AND i.index_id = ps.index_id
WHERE i.index_id < 2
AND o.is_ms_shipped = 0
ORDER BY o.name

True, for getting approximate row counts. User has to decide which he/she prefers.

The row counts in sys.dm_db_partition_stats and sys.partitions are accurate. The old inaccuracies that sysindexes had don't occur. While the documentation for sys.partitions says 'approximate', the value is in fact accurate.
