MySQL命令输出在命令行客户端中太宽

Question

我在Ubuntu中的终端模拟器mysql中使用lxterminal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：

但如果我在这里复制并粘贴它，输出会显示一个很好的表格：

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

我想知道是否可以将终端仿真器中的输出视为这样一个漂亮的表？

Answer 1

使用mysql的ego命令

来自mysql的help命令：

ego（\ G）发送命令到mysql服务器，垂直显示结果。

所以通过在你的\G上添加一个select，你可以得到一个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寻呼机及其-S选项，该选项可以切割宽线并为您提供可以使用箭头键滚动的输出：

mysql> pager less -S

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

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

如果您已完成寻呼机并希望返回stdout上的常规输出，请使用以下命令：

mysql> nopager

Answer 2

您也可以尝试调整终端的字体大小，但如果没有，则应该清除垂直输出。使用/ G选项运行查询，即

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

Answer 3

如果你在Ubuntu上运行，你可以使用bash shell，它看起来不错，而且不会像这样搞乱。
