命令行客户端中的MySQL命令输出太宽 [英] MySQL command output too wide in command-line client

问题描述

我在Ubuntu的终端仿真器lxterminal中使用mysql命令行客户端.当我运行以下命令时:

I am using mysql command line client in terminal emulator lxterminal in Ubuntu. When I run the following command:

mysql> select * from routines where routine_name = "simpleproc";

输出混乱:

但是，如果我将其复制并粘贴到此处，输出将为我显示一个漂亮的表:

But if I copy and paste it here, the output shows me a nice table:

mysql> select * from routines where routine_name = "simpleproc";

我想知道是否可以在终端仿真器中将输出查看为像这样的漂亮表?

I wonder if it is possible to view the output in a terminal emulator as a nice table like this one?

推荐答案

使用mysql的ego命令

通过mysql的help命令:

Using mysql's ego command

From mysql's help command:

ego((G))向mysql服务器发送命令，垂直显示结果.

ego          (\G) Send command to mysql server, display result vertically.

因此，通过将\G附加到select，您可以获得非常干净的垂直输出:

So by appending a \G to your select, you can get a very clean vertical output:

mysql> select * from routines where routine_name = "simpleproc" \G

使用寻呼机

您可以告诉MySQL使用less传呼器及其-S选项，该选项可以切掉粗线，并为您提供可以使用箭头键滚动的输出:

Using a pager

You can tell MySQL to use the less pager with its -S option that chops wide lines and gives you an output that you can scroll with the arrow keys:

mysql> pager less -S

因此，下次运行具有宽输出的命令时，MySQL将允许您使用less传呼机浏览输出:

Thus, next time you run a command with a wide output, MySQL will let you browse the output with the less pager:

mysql> select * from routines where routine_name = "simpleproc";

如果您已经完成了寻呼机，并且想要返回到stdout上的常规输出，请使用以下命令:

If you're done with the pager and want to go back to the regular output on stdout, use this:

mysql> nopager
