今儿在做实验用到mysql数据库时，用户密码忘记了，让我也是找了半天：现在给大家介绍下我自己的方法：用到了mysql自身的函数来测试的。
mysql> select user,password,host from user;
+------+------------------+-----------+
| user | password | host |
+------+------------------+-----------+
| root | 773359240eb9a1d9 | localhost |
| root | | fsailing1 |
| root | | 127.0.0.1 |
| root | 309e1248634a4f61 | % |
+------+------------------+-----------+
4 rows in set (0.00 sec)
mysql> password("root");
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'password("root")' at line 1
mysql> select password("root");
+------------------+
| password("root") |
+------------------+
| 67457e226a1a15bd |

mysql> select password("chen");
