    Thread moved from what's wrong with my code

    dbc:mydql
    Check spelling on the URL. There error however indicates the database does not exist. Can you log in through a terminal as root into that particular database?

    MySQL comes with the mysql tool which you can use to login to a database using the command line. Try connecting to your database this way. See the docs of Mysql for how to use this tool (for instance 'mysql.exe --help')
