@temprowcount is null and as such concatenating anything to it will yeild null (if ansi nulls is enabled)

In esence both of your query string variables will always be null.

[Code]

DECLARE @temprowcount varchar(255), @table varchar(255), @query varchar(1000)

SET @table = 'TestTable'

set @query = N'select '+ @temprowcount+' = count(*) from '+ @table;

select @Query

set @query = N'select @temprowcount = count(*) from '+ @table;

select @Query

[/Code]

rbarryyoung beat me to it, but I'll post this anyway. It does what you want, although not as useful as his view.

set nocount on

create table #temp(namet varchar(255),countf varchar(255))

exec sp_MSforeachtable 'insert #temp select ''?'', count(1) from ? with (nolock)'

Below query will return the row count of user tables in a db.

SELECT o.name AS "Table Name", i.rowcnt AS "Row Count"

FROM sysobjects o, sysindexes i

WHERE i.id = o.id AND indid IN(0,1)

AND xtype = 'u'

AND o.name <> 'sysdiagrams'

ORDER BY i.rowcnt DESC

--COMPUTE SUM(i.rowcnt)

GO

That can be quite inaccurate unless you use DBCC UPDATEUSAGE first.

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.

Change is inevitable... Change for the better is not.
