不同数据库oracle mysql SQL Server DB2 infomix sybase分页查询语句
在不同数据库中的使用的分页查询语句：
当前页:currentpage
页大小:pagesize
1. Oracle数据库
select * from (select A.*,rownum rn from ( QUERY_SQL ) A ) where rn <= ((currentpage+1)*pagesize) and rn > (currentpage*pagesize)
注：QUERY_SQL为查询sql语句。
或
select * from (select rownum rn,id from TABLENAME where rownum <=((currentpage+1)*pagesize) ) A where A.rn >= (currentpage*pagesize)
2. Infomix数据库
select skip currentpage first pagesize * from TABLENAME
3. DB2数据库
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 (currentpage*pagesize) and ((currentpage+1)*pagesize)
或
select * from (select rownumber() over(order by id asc ) as rowid from table where rowid <=((currentpage+1)*pagesize) ) where rowid > (currentpage*pagesize)
4. SQL Server数据库
select top pagesize *
from TABLENAME
where COLLUMN_NO not in
(select top currentpage*pagesize COLLUMN_NO from TABLENAME order by COLLUMN_NO)
order by COLLUMN_NO
5. Sybase数据库
Sybase 12.5.3版本支持top查询，或使用set rowcount N查询头N条数据
另外采用临时表：
select rowid=identity(12), column_name into #TEMPTABLE from TABLENAME
select column_name from #TEMPTABLE where rowid >(currentpage*pagesize) and rowid < (currentpage*pagesize+pagesize)
6. MySQL数据库
SELECT * FROM TABLE1 LIMIT (currentpage*pagesize),pagesize
