Dynamic WHERE clause with paging functionality in SQL 2005

Hi

I would like to pass a where clause as a parameter (e.g.: FirstName Like '%Jo%')

When I run this stored procedure in query analyzer I get:
Incorrect syntax near ')'.
Invalid object name 'ItemEntries'.

I followed an example on a previous question on expert exchange but the solution did not seem to work for me.

Seems to be the dynamic WITH  that throws an error.

Is it in anyway possible to resolve this problem?
ALTER PROCEDURE [dbo].[PagedUserList]
(
	@PageIndex int,
	@NumRows int,
	@SearchText nvarchar(1000)
)
AS
 
BEGIN
 
	DECLARE @nSQL nvarchar(1090)
	SET @nSQL = 'SELECT (SELECT COUNT(*) FROM Users WHERE '+@SearchText+') AS MemberCount'
	EXECUTE sp_executeSQL @nSQL
 
	
	DECLARE @startRowIndex int;
	SET @startRowIndex = (@PageIndex * @NumRows) + 1;
 
	DECLARE @wSQL nvarchar(1090)
	SET @wSQL = 'WITH ItemEntries AS (SELECT ROW_NUMBER() OVER (ORDER BY LastName DESC) AS Row, UserID, FirstName, LastName FROM Users WHERE '+@SearchText+')'
	EXEC sp_executesql @wSQL
	
	SELECT UserID, FirstName, LastName
	FROM ItemEntries
	WHERE Row between 
	@startRowIndex and @StartRowIndex+@NumRows-1
	
END

Hi

I made the parameter @SearchText redundent to eliminate how I may be passing this parameter and ran it again in query analyzer with the result below. I still get the same error


---------------------------
PagedUserList 1, 9
---------------------------
(1 row(s) affected)
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near ')'.
Msg 208, Level 16, State 1, Procedure PagedUserList, Line 24
Invalid object name 'ItemEntries'.
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
 
ALTER PROCEDURE [dbo].[PagedUserList]
(
	@PageIndex int,
	@NumRows int
	--@SearchText nvarchar(1000)
)
AS
 
BEGIN
 
	DECLARE @nSQL nvarchar(1090)
	SET @nSQL = 'SELECT (SELECT COUNT(*) FROM Users WHERE  Status = 1) AS MemberCount'
	EXECUTE sp_executeSQL @nSQL
 
	
	DECLARE @startRowIndex int;
	SET @startRowIndex = (@PageIndex * @NumRows) + 1;
 
	DECLARE @wSQL nvarchar(1090)
	SET @wSQL = 'WITH ItemEntries AS (SELECT ROW_NUMBER() OVER (ORDER BY LastName DESC) AS Row, UserID, FirstName, LastName FROM Users WHERE Status = 1)'
	EXEC sp_executesql @wSQL
	
	SELECT UserID, FirstName, LastName
	FROM ItemEntries
	WHERE Row between 
	@startRowIndex and @StartRowIndex+@NumRows-1
	
END

As u r using With clause the select query of the table with which

DECLARE @wSQL nvarchar(1090)
SET @wSQL = 'WITH ItemEntries AS (SELECT ROW_NUMBER() OVER (ORDER BY LastName DESC) AS Row, UserID, FirstName, LastName FROM Users WHERE Status = 1)
SELECT UserID, FirstName, LastName
FROM ItemEntries
WHERE Row between
@startRowIndex and @StartRowIndex+@NumRows-1 '

EXEC sp_executesql @wSQL

As u r using With clause the select query of the table with which With clase is attached should be embed within the string itself

This solution was great. The only thing I had to do was cast the int's to varchar within the string
