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
