在默认下，MySQL在use databasename的时候，是不显示连接的库名！

mysql> show databases;

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

| Database           |

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

| information_schema |

| hank               |

| mysql              |

| performance_schema |

| sakila             |

| test               |

| yoon               |

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

7 rows in set (0.00 sec)

mysql> use yoon;

Database changed

mysql>

可通过以下方式，实现显示连接的数据库名：

[root@hank-yoon tmp]# mysql --prompt="\u(\d) >"

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 29

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

root((none)) >use yoon;

Database changed

root(yoon) >

如果想显示连接的库名和时间：

[root@hank-yoon tmp]# mysql --prompt="\u(\d) \R:\m:\s >"

也可以添加在myf配置文件中，但是需要重启DB，生产库的话，可不是随便能重启，因此在连接的时候加上即可！
