SQL分页算法
create procedure pagination
@sqlstr nvarchar(4000), --查询字符串
@currentpage int, --第N页
@pagesize int --每页行数
as
set nocount on
declare @P1 int, --P1是游标的id
@rowcount int
exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output
select ceiling(1.0*@rowcount/@pagesize) as TotalPages,@rowcount as TotalRows,@currentpage as CurPage
set @currentpage=(@currentpage-1)*@pagesize+1
exec sp_cursorfetch @P1,16,@currentpage,@pagesize
exec sp_cursorclose @P1
set nocount off
--用法实例
exec pagination 'select * from Table1',1,10
--返回三个结果集,第一个是空的,第二个返回的列分别是总页数,总行数,当前页,第三个是查询的数据结果集。
