表中主键必须为标识列，[ID] int IDENTITY (1,1) 1.分页方案一：(利用Not In和SELECT TOP分页)语句形式： SELECT TOP 10 *FROM TestTableWHERE (ID NOT IN (SELECT TOP 20 id FROM TestTable ORDER BY id))ORDER BY IDSELECT TOP 页大小 *FROM TestTableWHERE (ID NOT IN (SELECT TOP 页大小*页数 id FROM 表 ORDER BY id))ORDER BY ID 2.分页方案二：(利用ID大于多少和SELECT TOP分页）语句形式： SELECT TOP 10 *FROM TestTableWHERE (ID > (SELECT MAX(id) FROM (SELECT TOP 20 id FROM TestTable ORDER BY id) AS T))ORDER BY IDSELECT TOP 页大小 *FROM TestTableWHERE (ID > (SELECT MAX(id) FROM (SELECT TOP 页大小*页数 id FROM 表 ORDER BY id) AS T))ORDER BY ID 3.分页方案三：(利用SQL的游标存储过程分页)create procedure SqlPager@sqlstr nvarchar(4000), --查询字符串@currentpage int, --第N页@pagesize int --每页行数asset nocount ondeclare @P1 int, --P1是游标的id @rowcount intexec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1, @rowcount=@rowcount outputselect ceiling(1.0*@rowcount/@pagesize) as 总页数--,@rowcount as 总行数,@currentpage as 当前页 set @currentpage=(@currentpage-1)*@pagesize+1exec sp_cursorfetch @P1,16,@currentpage,@pagesize exec sp_cursorclose @P1set nocount off
