今天登陆mysql show databases出现Ignoring query to other database错误，又试了几个命令和sql全部提示Ignoring query to other database错误
错误如下：
D:Program FilesMySQLMySQL Server 5.6in>mysql -root
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 66

mysql> show databases;
Ignoring query to other database
mysql> show tables;
Ignoring query to other database
折腾了半天才发现原来是在连接mysql时没有"-u"参数导致的
D:Program FilesMySQLMySQL Server 5.6in>mysql -uroot
重新连接mysql 加上-u参数 一切正常
