1.Oracle:
select * from ( select row_.*, rownum rownum_ from ( query_SQL ) row_ where rownum =< max) where rownum_ >= min
2.SQL Server:
select top @pagesize * from tablename where id not in (select top @pagesize*(@page-1) id from tablename order by id) order by id
3.MySQL
select * from tablename limit position, counter
4.DB2
select * from (select *,rownumber() as ROW_NEXT from tablename) where ROW_NEXT between min and max
语句形式:
SELECT TOP 10 * FROM TestTable WHERE (ID NOT IN (SELECT TOP 20 id FROM TestTable ORDERBY id)) ORDERBYID SELECT TOP 页大小 * FROM TestTable WHERE( ID NOT IN (SELECT TOP 每页大小-1*待查询页数-1 id FROM 表 ORDERBY id)) ORDERBYID
思路:先查询出待查询页之前的全部条数的id,查询ID不在这些ID中的指定数量条数。
语句形式:
SELECT TOP 10 * FROM TestTable WHERE(ID>(SELECT MAX(id) FROM(SELECT TOP20 id FROM TestTable ORDERBYid) AS T))ORDERBY ID SELECT TOP 页大小* FROM TestTable WHERE(ID>(SELECT MAX(id) FROM(SELECT TOP 每页大小*待查询页数-1 id FROM 表 ORDERBY id)AS T)) ORDERBY ID
思路:先获得待查询页的之前全部条数id,获得它们当中最大的ID号,以此最大ID号为标志,查找比这个ID号大的指定条数。
SELECT TOP PageSize * FROM (SELECT TOP nPage*PageSize * from YOURTABLE order by id) as a order by id desc SELECT TOP 每页条数 * FROM (SELECT TOP 待查询页*每页条数) * from YOURTABLE order by id)as a order by id desc
思路:先正排序查询出待查询页之前(包括当前页)的全部条数,然后将其倒排序,取指定条数。
