为什么mysql中用G表示按列方式显示

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:ProgramDataMicrosoftWindowsStart MenuProgramsMySQLMySQL 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 FilesMySQLMySQL Server 5.7inmysql.exe" "--defaults-file=C:ProgramDataMySQLMySQL Server 5.7my.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: ************
