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

mysql 控制臺程序的默認提示符為 "mysql>". 該提示符可用根據需要進行修改設置:

有以下幾種設置方式:

設置shell 的環境變量 : MYSQL_PS1

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

使用程序啟動命令選項 : --prompt

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

設置選項文件中的 [mysql] 節,添加 prompt 選項

[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>
