Interesting but I'm not sure why you would do this instead of:

select count(*) from TimeZones

What I find more helpful is to be able to return a list rowcounts for all tables in a database in tabular form. I found this somewhere (not original with me).

/* Display table name and rowcount using system tables */
SELECT
tbl.NAME AS [Table],
Coalesce( ( select sum (spart.rows) from sys.partitions spart
where spart.object_id = tbl.object_id and spart.index_id < 2), 0) AS [RowCount]
FROM sys.tables AS tbl
ORDER BY 1

I also get NULL as the result when I run this procedure.
I have set this procedure up to run as a stored procedure which takes TableName as a parameter to the function. It does not work as advertised in a SQL 2005 environment.

I also got one row with NULL, so I did not see much use for this SQL.

but Russel Bell, this is useful, thanks.

The problemwith all of you folks getting the Null is that you didn't read the script... it's setup to get the rowcount for a table called "TimeZones" which you probably don't have. You need to change the table name...

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

I must admit, though, there is absolutely no need for the dynamic SQL...

DECLARE @TableName   SYSNAME
SET @TableName = 'dbo.JBMTest' --LOOK!!!! CHANGE THE TABLE NAME!!!!
SELECT TOP 1 [Rows] FROM sys.Partitions WHERE Object_ID = OBJECT_ID(@TableName)

I may have another problem, but it most certainly isn't the table name. As I said, I made the script into a stored procedure:


/****** Object: StoredProcedure [dbo].[usp_GetTableRowCount]
Script Date: 09/30/2008 14:39:49 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


CREATE PROCEDURE [dbo].[usp_GetTableRowCount]
@TableName VARCHAR(100)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON

DECLARE @varSQL NVARCHAR(4000)
DECLARE @iCount INT
--SET @varSQL = 'SELECT TOP 1 @iCountOut = rows FROM sys.partitions where object_id = ' + CAST(object_id(@TableName) AS VARCHAR(100))
--EXECUTE sp_ExecuteSQL @varSQL, N'@iCountOut INT OUTPUT', @iCountOut = @iCount OUTPUT
--SELECT @iCount as [rowcount]

SELECT Coalesce( ( select sum (spart.rows) from sys.partitions spart
where spart.object_id = tbl.object_id and spart.index_id < 2), 0) AS [RowCount]
FROM sys.tables AS tbl where tbl.Name = CAST(object_id(@TableName) AS VARCHAR(100)) ORDER BY 1

END


And as I stated, it does not work.
Go
