The prompt command reconfigures the default mysql> prompt. The string for defining the prompt can contain the following special sequences.

mysql 控制台程序的默认提示符为 "mysql>". 该提示符可用根据需要进行修改设置:

有以下几种设置方式:

设置shell 的环境变量 : MYSQL_PS1

shell> export MYSQL_PS1="(\u@\h) [\d]> "

使用程序启动命令选项 : --prompt

shell> mysql --prompt="(\u@\h) [\d]> "
(user@host) [database]>

设置选项文件中的 [mysql] 节,添加 prompt 选项

[mysql]
prompt=(\\u@\\h) [\\d]>\\_
在 mysql 程序中使用 prompt (\R) 命令

mysql> prompt (\u@\h) [\d]>\_
PROMPT set to '(\u@\h) [\d]>\_'
(user@host) [database]>
(user@host) [database]> prompt
Returning to default PROMPT of mysql>
mysql>
