不同数据库Oracle MySQL SQL Server DB2 infomix sybase分页查询

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
