為什么mysql中用\G表示按列方式顯示

關於mysql的錯誤 - no query specified

學習了：http://blog.csdn.net/tenfyguo/article/details/7566941

sql語句可以用分號或者\G來結尾；出現這個錯誤一般是分號多寫了；

學習了：http://blog.csdn.net/guoqianqian5812/article/details/51754594

分號也可以換成 \g 

在Navicat中是不支持\G和\g標記的；

學習了：https://stackoverflow.com/questions/2277014/why-the-g-in-select-from-table-name-g  這個說的最明白了，膜拜一下org！

\G表示 go的意思；

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

學習了：https://www.2cto.com/database/201212/178075.html 老外說的還針對，

使用-E的話，的確以列方式顯示；但是-E登錄之后沒有辦法按行顯示了；

-E登錄的方法，在開始菜單里面：C:\ProgramData\Microsoft\Windows\Start Menu\Programs\MySQL\MySQL Server 5.7，復制

MySQL 5.7 Command Line Client - Unicode 然后修改其中的屬性，添加-E選項，

"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登錄之后就有\g是結束符的提示：

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