Qt连接MySql数据库问题
Qt连接MySql数据库的时候，报这样的错误：
"Access denied for user 'root'@'LBDZ-08140011' (using password: YES) QMYSQL: Unable to connect"。
我上网查了一下，别人说的是密码用户名和密码有误。
我这里有点小疑惑，想问一下：
我在安装mysql的时候没有设置用户名这一项，网上说用户名是默认的root，密码就是自己设置的密码，是这样吗？
如果是的话那我在连接mysql数据库的时候，用户名和密码都没错啊，这个问题又该怎样解决？
[解决办法]
百度知道的结果，自己没有mysql，没法试希望对你有帮助。

[解决办法]
MySQL的用户权限是分的很清的，
要新建一个用户，要为该用户赋予网络的权限才行。
[解决办法]
打开mysql:
use mysql;
select * from user where user='root'\G;
看一下host限制了谁。
