HomeDatabaseMysql TutorialMySQL分页的实现_MySQL

mysql> select pname from product;
+--------+
| pname  |
+--------+
| 产品1  |
| 产品2  |
| 产品三 |
+--------+
3 rows in set (0.00 sec)
这个地方是说,从product中选出所有的pname来,一共有三条记录。   MySQL中的分页非常简单,我们可以使用limit   比如:
mysql> select pname from product limit 0,2;
+-------+
| pname |
+-------+
| 产品1 |
| 产品2 |
+-------+
2 rows in set (0.00 sec)
Limit用法如下:   第一个参数是指要开始的地方,第二个参数是指每页显示多少条数据;注意:第一页用0表示。   Mysql分页:   select * from tableName where 条件 limit 当前页码*页面容量-1 , 页面容量
