Ignoring query to other database

登录mysql时，显示如下问题：

/usr/local/mysql/bin/mysql -root -plynnteng0
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 57111199

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

mysql> show databases;
Ignoring query to other database

 

这是因为输入命令的时候，漏了一个"u”

是把-root当成参数了吗？那为什么能够登录不能操作呢？

具体情况未知。。。
