先来定义分页语句将要用到的几个参数：
int currentPage ; //当前页
int pageRecord ; //每页显示记录数
以之前的ADDRESSBOOK数据表为例(每页显示10条记录)：
一、SqlServe下载 分页语句
|
1
2
|
String sql = "select top "+pageRecord +" * from addressbook where id not in (select top "+(currentPage-)*pageRecord +" id from t_user)"; // (currentPage-)*pageRecord : 是指从第几个记录开始 |
第二页SQL演示：
|
1
|
select top 20 * from addressbook where id not in (select top 10 id from addressbook) |
|
1
2
3
4
|
String sql = "select * from addressbook where limit "+(currentPage-)*pageRecord +","+pageRecord +""; //select * from 表名 【条件】limit M,N; //M为从第几个记录开始，比如每页显示条记录，第二页就必须从第条记录开始 //N每页读几个数据 |
第二页SQL演示：
|
1
|
select * from addressbook where limit 10,10 |
三、Oracle数据库分页语句
|
1
|
String sqls = "select * from ( select rownum rn,t.* from addressbook t where rownum <= "+currentPage*pageRecord+" ) where rownum > "+(currentPage -1)*pageRecord; |
第二页SQL演示：
|
1
|
select * from ( select rownum rn,t.* from addressbook where rownum<= 20 ) where rownum > 10 |
以上所述是小编给大家介绍的Oracle、MySQL和SqlServe三种数据库分页查询语句的区别介绍，希望对大家有所帮助！
