关于mysql的错误 - no query specified

学习了：http://blog.csdn.net/tenfyguo/article/details/7566941

sql语句可以用分号或者\G来结尾；出现这个错误一般是分号多写了；

分号也可以换成 \g

在Navicat中是不支持\G和\g标记的；

学习了：https://stackoverflow.com/questions/2277014/why-the-g-in-select-from-table-name-g  这个说的最明白了，膜拜一下org！

\G表示 go的意思；

In summary...

--vertical >> -E >> ego >> \G ...Tada !

学习了：https://www.2cto.com/database/201212/178075.html 老外说的还针对，

使用-E的话，的确以列方式显示；但是-E登录之后没有办法按行显示了；

-E登录的方法，在开始菜单里面：C:\ProgramData\Microsoft\Windows\Start Menu\Programs\MySQL\MySQL Server 5.7，复制

MySQL 5.7 Command Line Client - Unicode 然后修改其中的属性，添加-E选项，

"C:\Program Files\MySQL\MySQL Server 5.7\bin\mysql.exe" "--defaults-file=C:\ProgramData\MySQL\MySQL Server 5.7\my.ini" "-uroot" "-E" "-p" "--default-character-set=utf8"

mysql登录之后就有\g是结束符的提示：

Enter password: ************

Welcome to the MySQL monitor. Commands end with ; or \g.
