MySQL显示连接的数据库名

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
Server version: 5.6.26-log Source distribution

owners.

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 >"

Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 30
Server version: 5.6.26-log Source distribution

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

root((none)) 15:20:08 >use yoon
Database changed
root(yoon) 15:20:16 >

也可以添加在my.cnf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！
[mysql]
default-character-set = utf8
prompt = \\u(\\d) \\R:\\m:\\s > \
