Hi there,

I'm new to T-SQL and i'm trying to implement the efficient paging method outlined in scottgu's article: http://weblogs.asp.net/scottgu/archive/2006/01/07/434787.aspx

The problem is i'm trying to make the stored procedure Dynamic, but when I run the following Stored procedure I get the following error:

Incorrect syntax near ')'.
Invalid object name 'ItemEntries'.

It looks like it is to do with the common table expression "ItemEntries". What would be the correct syntax for the following dynamic sql:

SET @sqlString = 'With ItemEntries as (
SELECT ROW_NUMBER() OVER (ORDER BY price ASC) as Row, dogID
FROM tblDogs
WHERE ' + @whereClause + ')'

EXEC(@sqlString)

Any help would be very much appreciated, thanks

AT LAST I FIGURED IT OUT!!

if anybody else is interested...

when executing a common table expression (CTE) you must also include the statement that immediately follows it and uses the CTE e.g.

Declare @startRowIndex INT;
Declare @endRowIndex INT;
set @startRowIndex = (@pageIndex * @numRows) + 1;
set @endRowIndex = (@StartRowIndex+@NumRows-1);

EXEC('WITH ItemEntries AS (SELECT ROW_NUMBER() OVER (ORDER BY dogID ASC) AS Row, dogID FROM tblDogs WHERE ' + @whereClause + ')

Select dogID

FROM ItemEntries

WHERE Row between ' + @startRowIndex + ' and ' + @endRowIndex);
