I'm working with some SQL that uses true paging.
I would like to be able pass in a where clause and an order by to the stored procedure.
How can I implement t?
Can i build dynamic sql and then use sp_executesql ? Or is there another method?
ALTER PROCEDURE IMINVLOC_SQL_Paged
@Where varchar(2000) = NULL,
@OrderBy varchar(2000) = NULL,
@PageIndex int,
@PageSize int
AS
 
BEGIN
	DECLARE @SQL nvarchar(2000)
	DECLARE @Count int
	SELECT @Count = (SELECT COUNT(*) FROM IMINVLOC_SQL)
	
	DECLARE @StartRowIndex int
	SET @StartRowIndex = (@PageIndex * @PageSize) + 1;
	
	WITH Results AS (
		SELECT ROW_NUMBER() OVER (ORDER BY Item_No ASC) AS Row, Item_No, Item_Filler, Std_Cost
		FROM IMINVLOC_SQL
	)
	
	SELECT Item_No, Item_Filler, Std_Cost, @Count As TotalRecords
	FROM Results
	WHERE Row BETWEEN
	@StartRowIndex AND @StartRowIndex + @PageSize - 1
 
END

its better to use dynamic sql rather than putting a big case statement

thank you for your reply,
will i be able to put this in dynamic sql? I'm not familiar with the "WITH" statement.

WITH Results AS (
            SELECT ROW_NUMBER() OVER (ORDER BY Item_No ASC) AS Row, Item_No, Item_Filler, Std_Cost
            FROM IMINVLOC_SQL
      )
      
      SELECT Item_No, Item_Filler, Std_Cost, @Count As TotalRecords
      FROM Results
      WHERE Row BETWEEN
      @StartRowIndex AND @StartRowIndex + @PageSize - 1

yes you can include with in dynamic sql.
try like this

I didnt include checks on @OrderBy and @Where for zero length or null values.
add the checks within the procedure if you are not validating the input before you call the stored procedure.
ALTER PROCEDURE IMINVLOC_SQL_Paged
@Where varchar(2000) = NULL,
@OrderBy varchar(2000) = NULL,
@PageIndex int,
@PageSize int
AS
 
BEGIN
	DECLARE @SQL nvarchar(8000)
	DECLARE @Count int
	SELECT @Count = (SELECT COUNT(*) FROM IMINVLOC_SQL)
	
	DECLARE @StartRowIndex int
	SET @StartRowIndex = (@PageIndex * @PageSize) + 1;
	
	SET @SQL = ';WITH Results AS (
		SELECT ROW_NUMBER() OVER (ORDER BY ' + @OrderBy + ') AS Row, Item_No, Item_Filler, Std_Cost
		FROM IMINVLOC_SQL Where ' + @Where + ' )
	SELECT Item_No, Item_Filler, Std_Cost, @Count As TotalRecords
	FROM Results
	WHERE Row BETWEEN ' +  @StartRowIndex + ' AND ' +   @StartRowIndex + @PageSize - 1 ;
 
	Exec(@SQL);
 
END
