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 Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective 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 Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. 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！
