MySQL显示操作控制小技巧

MySQL 显现格式化

一、使用G按行垂直显示结果

未使用

mysql> select * from wp_users limit 1,2;

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

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

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

2 rows in set (0.00 sec)

使用

mysql> select * from wp_users limit 1,2\G;

*************************** 1. row ***************************

ID: 2

user_login: NicholaJorgenson

user_pass: $P$BrLC6ljpc5i6IvCw4V2dTHn.ZTrXd/1

user_nicename: nicholajorgenson

user_email: almatrostelgt3776@yahoo.com

user_url:

user_registered: 2015-02-15 09:40:54

user_activation_key:

user_status: 0

display_name: NicholaJorgenson

*************************** 2. row ***************************

ID: 3

user_login: ElvinMoney

user_pass: $P$BebFywousFh0mVmoqHEWAx7IofQmEJ0

user_nicename: elvinmoney

user_email: alizanoguera@mailcatch.com

user_url:

user_registered: 2015-02-15 10:04:36

user_activation_key:

user_status: 0

display_name: ElvinMoney

2 rows in set (0.00 sec)

二、使用pager来设置翻页

pager 'more' 此模式会显示一页，等待按键再显示一页

pager 'less' 此模式会显示一页，等待按键再显示一行

nopager 此模式直接显示到最完

三、使用tee保存运行结果到文件，类似于Oracle中的spool命令

mysql> tee test.txt

Logging to file 'test.txt'

select * from wp_users limit 1,2;

mysql> notee

mysql> quit

Bye

[mysql@sam ~]$ cat test.txt

mysql> select * from wp_users limit 1,2;

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

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

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

2 rows in set (0.00 sec)

mysql> notee

[mysql@sam ~]$

四、直接执行操作系统命令

mysql> system ls -l

total 10092

-rw-rw-r-- 1 mysql mysql 1638854 Apr 22 16:05 backup1.sql

-rw-rw-r-- 1 mysql mysql 1767787 Apr 23 10:49 backup2.sql

-rw-rw-r-- 1 mysql mysql 13807 Apr 23 09:48 backup3.sql

-rw-rw-r-- 1 mysql mysql 12258 Apr 23 10:53 backup4.sql

-rw-rw-r-- 1 mysql mysql 2293238 Apr 23 11:03 backup5.sql

-rw-rw-r-- 1 mysql mysql 2297583 Apr 23 11:16 backup6.sql

-rw-rw-r-- 1 mysql mysql 2297579 Apr 23 11:23 backup7.sql

-rw-rw-r-- 1 mysql mysql 1280 Aug 26 11:18 test.txt

五、执行SQL文件脚本

mysql> source 1.sql

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

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

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

2 rows in set (0.00 sec)

mysql> system cat 1.sql

select * from wp_users limit 1,2;

mysql>

六、修改命令提示符

mysql> prompt \u@\h(\d) \r:\m:\s:>

PROMPT set to '\u@\h(\d) \r:\m:\s:>'

sam@localhost(wordpress) 03:15:28:>
