How do I access an OpenShift MySql database via Jdbc via the Google Spreadsheet?

I want to access a MySql bank hosted on OpenShift via Jdbc from the Google Spreadsheet. Is it possible?

In Google Spreadsheet, in Ferramentas -> Editor de Scripts , I'm having problems with the connection string that is in this format:

var connection = Jdbc.getConnection(
    "jdbc:mysql://HOST:PORTA/DB_NAME", "USERPHPMYADMIN", "SENHAPHPMYADMIN");
