RE: Get Record Count for each table in a database.

[quote][b]rbarryyoung (8/10/2008)[/b][hr]Hmm, yeah I see where it says that Jeff. I may be wrong here, when I wrote my view (about 2-3 years ago) I was still working on both 2000 & 2005 most days and I remember having accuracy problems that ultimately caused my to add DBCC UpdateUsage periodically. But it [i]may[/i] have been only happening on SQL 2000.[/quote]Either way, it doesn't hurt to update usage as long as you have the time. The important thing about any of these techniques (yours, mine and Jeff's) are that they are not cursor based and return the desired results.

[quote][b]Jeffrey Williams (8/10/2008)[/b][hr]Well, according to BOL - no, you don't have to update usage.[/quote]Hmm, yeah I see where it says that Jeff.

... and, with SQL Server 2000, we end up with this...[code] DBCC UPDATEUSAGE (0) SELECT so.Name AS TableName, si.Rows AS [Rows] FROM dbo.SysObjects so INNER JOIN dbo.SysIndexes si ON si.ID = so.ID WHERE si.IndID < 2 AND so.XType = 'U' AND OBJECTPROPERTY(so.ID,'IsMSShipped') = 0[/code]Yeah... I know... if I didn't use the two part naming convention, they'd both work and they'd both be identical. Actually, the code above will work in both environments... I just have an affinity for the two part naming convention for a lot of reasons. :P

So... hedging a bet against BOL and changing the code to something a bit more conventional, we end up with this...[code] DBCC UPDATEUSAGE (0) SELECT so.Name AS TableName, si.Rows AS [Rows] FROM sys.SysObjects so INNER JOIN sys.SysIndexes si ON si.ID = so.ID WHERE si.IndID < 2 AND so.XType = 'U' AND OBJECTPROPERTY(so.ID,'IsMSShipped') = 0[/code]

Since I went ahead and made the query which actually does provide the table and associated rowsize without cursors thought I would post it. (though I am sure Barry's does a LOT more ).[code]SELECT so.name 'Table', si.rows 'Rows' FROM (SELECT Name FROM sysobjects WHERE type='U') so JOIN (SELECT rows,id,indid FROM sysindexes) si ON si.id = OBJECT_ID(so.name) AND si.indid < 2[/code]Toni

[quote][b]Jeff Moden (8/10/2008)[/b][hr]Again, I ask... do you have to update usage for the rowcounts to be accurate?[/quote]Well, according to BOL - no, you don't have to update usage.[quote]Reports and corrects pages and row count inaccuracies in the catalog views. These inaccuracies may cause incorrect space usage reports returned by the sp_spaceused system stored procedure. In SQL Server 2005 and later, these values are always maintained correctly. Databases upgraded from SQL Server 2000 may contain invalid counts. We recommend running DBCC UPDATEUSAGE after upgrading to correct any invalid counts.[/quote]But, as we all know - BOL is not always correct. There are situations where you will need to update usage, but I am not sure what those are. We just went through a large purge operation and these numbers were updated accurately.

But unless it is a table with rapidly shifting contents, you shouldn't have to do it every time. Besides, I couldn't put it in my view anyway. :)

[quote][b]Jeffrey Williams (8/10/2008)[/b][hr]For SQL Server 2005 and greater - there is no need to cursor at all. Just use the DMV sys.dm_db_partition_stats as in the following:[code] Select object_schema_name(object_id) As SchemaName ,object_name(object_id) As ObjectName ,row_count From sys.dm_db_partition_stats Where index_id < 2 And object_schema_name(object_id) <> 'sys' Order By object_schema_name(object_id);[/code][/quote]Again, I ask... do you have to update usage for the rowcounts to be accurate?

Jeff Moden — Sun, 10 Aug 2008 10:32:51 GMT

Aye... that's more like it.The only thing I'd be worried about is... do you need to update usage (DBCC UPDATEUSAGE) as you do in SQL Server 2000 to get accurate row counts?

Now [i]this view[/i] can get the estimated row counts (and a lot more besides)without cursors: [url]http://www.sqlservercentral.com/scripts/tables/62545/[/url]

toniupstny — Sun, 10 Aug 2008 10:18:07 GMT

Thanks Jeff. I was just looking through the code for the sp_MSforeach procedures (generated a Create for sp_MSforeachtable, sp_MSforeachworker and the sp_ MSforeach_worker) to see why the table one couldn't be called from the database one. I saw the cursor like you said right there so was coming back to post a "NEVERMIND"! Hey... I learned something anyway... thanks again.Toni

[quote][b]toniupstny (8/10/2008)[/b][hr]An alternative without cursor is:[center]sp_msforeachtable 'select ''?'', count(*) Rows from ?'[/center]Toni[/quote]Ummm.... not quite correct, Toni. If you go and look at the code for sp_MSForEachTable, you'll find a monster cursor that is typically slower than any cursor you would ever intentionally build because it was written to handle just about any size code. The cursor that Hari wrote will likely run much faster than using sp_MSForEachTable.
