Trudność w pisaniu Stored Proc w celu pobrania danych dla paginacji Jqgrid

Wydaje mi się, że możesz naprawić kod za pomocą OrderBy w GetFirst i GetNext częścią Klauzuli WITH, ale nie w GetAll część. Odpowiedni kod będzie dotyczył następujących

ALTER PROCEDURE [dbo].[NewStoredProc] 
(
    @skip int,
    @pageSize int,
    @OrderBy Varchar(20),
    @OrderByDirection Varchar(10)
 )

AS
BEGIN
    DECLARE @records int;
    SET NOCOUNT ON;
    SET @records =(select count(*) from Data where Status='A');

    IF @skip <= 0
        SELECT TOP (@pageSize) * from Data where Status='A' 
        ORDER BY CASE WHEN @OrderBy='Column1' AND @OrderByDirection='D'
                      THEN Column1
                 END DESC,
                 CASE WHEN @OrderBy='Column1' AND @OrderByDirection !='D'
                      THEN Column1
                 END,
                 CASE WHEN @OrderBy='Column2' AND @OrderByDirection='D'
                      THEN Column2
                 END DESC,
                 CASE WHEN @OrderBy='Column2' AND @OrderByDirection !='D'
                      THEN Column2
                 END,
                 CASE WHEN @OrderBy='Column3' AND @OrderByDirection='D'
                      THEN Column3
                 END DESC,
                 CASE WHEN @OrderBy='Column3' AND @OrderByDirection !='D'
                      THEN Column3

    ELSE
