 ALTER PROCEDURE [dbo].[A_PagingAndSorting]
     (
       @PageSize INT ,
       @PageIndex INT   --从1开始
     )
 AS
     BEGIN
     -- SET NOCOUNT ON added to prevent extra result sets from
     -- interfering with SELECT statements.
         SET NOCOUNT ON;

 ----------------------------------------------第一种方法：借助row_number()函数-------------------------------
         SELECT  A.ID ,
                 A.NAME ,
                 A.Age
         FROM    ( SELECT    ROW_NUMBER() OVER ( ORDER BY t.ID ASC ) AS RowNumber ,
                             t.ID ,
                             t.NAME ,
                             t.Age
                   FROM      dbo.Test t
                 ) AS A
         WHERE   A.RowNumber BETWEEN ( @PageIndex - 1 ) * @PageSize + 1
                             AND     @PageIndex * @PageSize

 --------------------------------------------第二中方法：借助表变量-------------------------------------
         DECLARE @T TABLE
             (
               ID INT IDENTITY(1, 1) ,
               nid INT
             )   

         INSERT  @T
                 ( nid )
                 SELECT  Te.ID
                 FROM    dbo.Test Te

         SELECT  Te.ID ,
                 Te.NAME ,
                 Te.Age
         FROM    @T T
                 INNER JOIN dbo.Test Te ON Te.ID = T.nid
         WHERE   T.ID BETWEEN ( @PageIndex - 1 ) * @PageSize + 1
                      AND     @PageIndex * @PageSize

 --------------------------------------------第三种方法：top---------------------------------------
         SELECT  *
         FROM    ( SELECT TOP ( @PageSize )
                             *
                   FROM      ( SELECT TOP ( @PageIndex * @PageSize )
                                         *
                               FROM      dbo.Test A
                               ORDER BY  A.ID ASC
                             ) B
                   ORDER BY  B.ID DESC
                 ) C
         ORDER BY c.ID
     END
