Mysql5.7修改用户密码，报错“Unknown trigger has an error in its body: ‘Unknown system variable ‘maintain_user”
Mysql5.7更改用户密码，报错“Unknown trigger has an error in its body: 'Unknown system variable 'maintain_user”，这里是因为恢复数据后，直接通过“skip-grant-tables”进入Mysql修改用户密码，忽略了触发器造成的，报出上面的错误。正常情况下，mysql5.7用户密码修改，口令为：mysql> update mysql.user set authentication_string
