MySQL的错误：No query specified

在做MySQL主从同步的时候通过：

mysql> show slave status\G;
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: 192.168.18.139
                  Master_User: rep

        Seconds_Behind_Master: 0
Master_SSL_Verify_Server_Cert: No
             Master_Server_Id: 3
1 row in set (0.00 sec)

ERROR:
No query specified    ==>出现此错误

出现此错误的原因是因为执行命令：show slave status\G;的时候，多加了一个“;”分号。

当执行命令的时候去掉分号，就不会出现此错误。

mysql> show slave status\G
