    if object_ID('[proc_SelectForPager]') is not null
    Drop Procedure [proc_SelectForPager]
    Go
    Create Proc proc_SelectForPager
    (
    @Sql varchar(max) ,
    @Order varchar(4000) ,
    @CurrentPage int ,
    @PageSize int,
    @TotalCount int output
    )
    As
    /*Andy 2012-2-28 */
    Declare @Exec_sql nvarchar(max)

    Set @Exec_sql='Set @TotalCount=(Select Count(1) From ('+@Sql+') As a)'
    Exec sp_executesql @Exec_sql,N'@TotalCount int output',@TotalCount output

    Set @Order=isnull(' Order by '+nullif(@Order,''),' Order By getdate()')

    if @CurrentPage=1 /*经常会调用第1页,这里做特殊处理,少一层子查询*/
    Set @Exec_sql='
    ;With CTE_Exec As
    (
    '+@Sql+'
    )
    Select Top(@pagesize) *,row_number() Over('+@Order+') As r From CTE_Exec Order By r
    '
    Else
    Set @Exec_sql='
    ;With CTE_Exec As
    (
    Select *,row_number() Over('+@Order+') As r From ('+@Sql+') As a
    )
    Select * From CTE_Exec Where r Between (@CurrentPage-1)*@pagesize+1 And @CurrentPage*@pagesize Order By r
    '


    Exec sp_executesql @Exec_sql,N'@CurrentPage int,@PageSize int',@CurrentPage,@PageSize

    Go

    1.单表:

    Exec proc_SelectForPager @Sql = 'Select * from contacts a where a.ContactType=1', -- varchar(max)
            @Order = '', -- varchar(4000)
            @CurrentPage = 3, -- int
            @PageSize = 20, -- int
            @TotalCount = 0 -- int

    2.多表联接:

    复制代码
    Exec proc_SelectForPager @Sql = 
        'Select a.Staff,a.OU,b.FName+b.FName as Name 
                from staffOUHIST a 
                    inner join Staff b on b.ID=a.Staff and a.ExpiryDate=''30001231''
            ', -- varchar(max)
            @Order = '', -- varchar(4000)
            @CurrentPage = 3, -- int
            @PageSize = 20, -- int
