查看MySQL的版本,主要有以下几个方法:

1. 没有连接到MySQL服务器,就想查看MySQL的版本。打开cmd,切换至mysql的bin目录,运行下面的命令即可:

e:\mysql\bin>mysql -V

mysql  Ver 14.14 Distrib 5.6.32, for Win32 (AMD64)

(版本为 5.6.32)

或者:

e:\mysql\bin>mysql -v

这个命令可以查看到更为详细的信息,因为它会用账号 ODBC,连接上MySQL服务器,默认连接到localhost上的3306端口。

或者:

e:\mysql\bin>mysql --help | find "Distrib"

mysql  Ver 14.14 Distrib 5.6.32, for Win32 (AMD64)

这种方式只有windows系统下才可用,因为windows中才用find命令查找字符串,且后面的字符串必须用双引号包裹起来,而linux系统下虽然也是用 | 作为管道符,却是使用grep命令查找字符串(如:mysql --help | grep Distrib)。

2. 如果已经连接到了MySQL服务器,则运行下面的命令:

mysql> select version();

+------------+

| version()  |

+------------+

| 5.6.32-log |

+------------+

1 row in set (0.00 sec)

或者:

mysql> status;

3. 在命令行连接上MySQL服务器时,其实就已经显示了MySQL的版本,如:

e:\mysql\bin>mysql -uroot -p -P3307

Enter password:

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

Your MySQL connection id is 10
