Ignoring query to other database

Mysql错误:Ignoring query to other database解决方法

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：

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

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 或没有-p
mysql -uroot

重新连接mysql　加上-u参数　一切正常
