命令行客户端中的MySQL命令输出太宽

Question

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

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

输出是一团糟：

但是，如果我将其复制并粘贴到此处，输出将显示一个漂亮的表：

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？

Answer 1

使用mysql的ego命令

从mysql的help命令：

自我（\ G）发送命令到mysql服务器，垂直显示结果。

因此，通过将追加\G到select，可以得到非常干净的垂直输出：

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

使用寻呼机

您可以告诉MySQL使用less带有分页符的-S选项的分页器，该分页器会切掉粗线，并为您提供可以使用箭头键滚动的输出：

mysql> pager less -S

因此，下次您运行带有宽输出的命令时，MySQL将允许您使用less寻呼机浏览输出：

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

如果您已经完成了寻呼机的工作，并且想返回到的常规输出stdout，请使用以下命令：

mysql> nopager
