一、思维脑图

1.登录、退出mysql

C:\windows\system32>mysql -uroot -pEnter password: ******Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 8Server version: 5.5.27 MySQL Community Server (GPL)Copyright (c) 2000, 2011, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement

2.修改命令提示符

C:\windows\system32>mysql -uroot -p --prompt=kingEnter password: ******Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 12Server version: 5.5.27 MySQL Community Server (GPL)Copyright (c) 2000, 2011, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.# 通过命令修改kingprompt \uPROMPT set to '\u'rootprompt \hPROMPT set to '\h'localhostprompt \h~\u~\D~\dPROMPT set to '\h~\u~\D~\d'localhost~root~Mon Jul 06 18:42:45 2020~(none)prompt mysql>PROMPT set to 'mysql>'mysql>

3.MYSQL常用命令

mysql>SELECT VERSION();+-----------+| VERSION() |+-----------+| 5.5.27    |+-----------+1 row in set (0.00 sec)mysql>select now();+---------------------+| now()               |+---------------------+| 2020-07-06 18:50:43 |+---------------------+1 row in set (0.00 sec)mysql>SELECT USER();+----------------+| USER()         |+----------------+| root@localhost |+----------------+1 row in set (0.00 sec)

4.MYSQL 语句规范

#折行操作mysql>SELECT    ->    -> NOW()    -> ;+---------------------+| NOW()               |+---------------------+| 2020-07-06 18:53:16 |+---------------------+1 row in set (0.00 sec)#引号成对出现mysql>SELECT NOW()'    '> ;    '> ';+---------------------+| ;                  |+---------------------+| 2020-07-06 18:56:50 |+---------------------+1 row in set, 1 warning (0.00 sec)

5，补充

1）\c的作用

作用：取消当前输入，当前输入不会执行

mysql>SELECT NOW()\cmysql>

2)修改默认的命令分隔符

mysql>DELIMITER //mysql>SELECT NOW();    -> //+---------------------+| NOW()               |+---------------------+| 2020-07-06 19:02:47 |+---------------------+1 row in set (0.00 sec)C:\windows\system32>mysql -uroot -p --delimiter=//Enter password: ******

3）上下键调用之前已输入命令

4）开启输出日志

mysql> \T D:\MYSQL\MYSQLDEMO\mysql1.txtLogging to file 'D:\MYSQL\MYSQLDEMO\mysql1.txt'mysql> SELECT NOW();    -> //+---------------------+| NOW()               |+---------------------+| 2020-07-06 19:15:11 |+---------------------+1 row in set (0.00 sec)mysql> DELIMITER ;mysql> \t  # 退出日志Outfile disabled.
