mysql中limit使用

mysql中没有top，替而代之的是limit关键字，具体使用方法如下：

mysql> select * from test;

+----+------+-----+----------+--------------+

| id | name | age | tel | address |

+----+------+-----+----------+--------------+

| 1 | aaaa | 12 | aaaaaa | aaaaaaaaa |

| 2 | bbbb | 12 | 12312312 | asgdsf |

| 3 | bbb | 23 | 123423 | asdfsafd |

| 5 | asdf | 23 | asfdsd | asdgesadg |

| 7 | sadf | 23 | asgsdg | asgsdfsafsdf |

+----+------+-----+----------+--------------+

5 rows in set (0.00 sec)

mysql> select * from test limit 2,5

-> ;
