sql server,mysql,oracle 三中数据库分页方式,很有必要的。

sql server:

String sql =

"select top " + pageSize + " * from students where id not in" +

"(select top " + pageSize * (pageNumber-1) + " id from students order by id)" +

"order by id";

mysql:

String sql =

"select * from students order by id limit " + pageSize*(pageNumber-1) + "," +

pageSize;

oracle:

String sql =

"select * from " +

(select *,rownum rid from (select * from students order by postime desc) where

rid<=" + pagesize*pagenumber + ") as t" +

"where t>" + pageSize*(pageNumber-1);
