Sql语句分页，有待优化

create procedure paging_procedure
(   @pageIndex int, -- 第几页
    @pageSize int,  -- 每页包含的记录数
    @moreTable text,--查询哪个表（支持多表链接查询）
    @orderBy varchar(200),--排序的字段
    @isAD varchar(100)-- asc还是desc排序
)
as
begin
    select top (select @pageSize) * 
    from (select row_number() over(order by @orderBy @isAD) as rownumber,* 
            from @tabName) temp_row 
    where rownumber>(@pageIndex-1)*@pageSize;
end

select top (select 2) *     
from (select row_number() over(order by ID asc) as rownumber,* 
        from SysError) temp_row 
where rownumber>(2)*2
