SELECT * FROM (Select 字段1,字段2,字段3,rownumber() over(ORDER BY 排序用的列名 ASC) AS rn from 表名) AS a1 WHERE a1.rn BETWEEN 10 AND 20
以上表示提取第10到20的纪录
select * from (select rownumber() over(order by id asc ) as rowid from table where rowid <=endIndex ) where rowid > startIndex
如果Order By 的字段有重复的值,那一定要把此字段放到 over()中
select * from ( select ROW_NUMBER() OVER(ORDER BY DOC_UUID DESC) AS ROWNUM, DOC_UUID, DOC_DISPATCHORG, DOC_SIGNER, DOC_TITLE from DT_DOCUMENT ) a where
ROWNUM > 20 and ROWNUM <=30
增加行号,不排序
select * from ( select ROW_NUMBER() OVER() AS ROWNUM,t.* from DT_DOCUMENT t ) a
增加行号,按某列排序
select * from ( select ROW_NUMBER() OVER( ORDER BY DOC_UUID DESC ) AS ROWNUM,t.* from DT_DOCUMENT t ) a
二、Mysql:
最简单
select * from table limit start,pageNum
比如从10取20个数据
select * from table limit 10,20
三、Oracle:
select * from (select rownum,name from table where rownum <=endIndex ) where rownum > startIndex
例如从表Sys_option(主键为sys_id)中从10条记录还是检索20条记录,语句如下:
SELECT *
FROM (SELECT ROWNUM R,t1.* From Sys_option where rownum < 30 ) t2
Where t2.R >= 10
四、 sql server:
分页方案一:(利用Not In和SELECT TOP分页) 语句形式: SELECT TOP 10 * FROM TestTable WHERE (ID NOT IN (SELECT TOP 20 id FROM TestTable ORDER BY id)) ORDER BY ID
SELECT TOP 页大小 * FROM TestTable WHERE (ID NOT IN (SELECT TOP 页大小*页数 id FROM 表 ORDER BY id)) ORDER BY ID
-------------------------------------
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 TestTable WHERE (ID > (SELECT MAX(id) FROM (SELECT TOP 20 id FROM TestTable ORDER BY id) AS T)) ORDER BY ID
SELECT TOP 页大小 * FROM TestTable WHERE (ID > (SELECT MAX(id) FROM (SELECT TOP 页大小*页数 id FROM 表 ORDER BY id) AS T)) ORDER BY ID
-------------------------------------
分页方案三:(利用SQL的游标存储过程分页) create procedure XiaoZhengGe @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 总页数--,@rowcount as 总行数,@currentpage as 当前页 set @currentpage=(@currentpage-1)*@pagesize+1 exec sp_cursorfetch @P1,16,@currentpage,@pagesize exec sp_cursorclose @P1 set nocount off
