Your qa_get_mysql_user_column_type() function should just return a single string indicating the column type, such as 'VARCHAR(15)'. But I'm not sure you're using the single sign-on appropriately, since it's for the situation where you already have a user database on your site. Also, it will require some PHP programming which is specific to your particular site. So perhaps you should use the installation process which lets Q2A manage users for you?
