I need help deploying an application that uses a mysql db. The application runs fine in the studio but when I transfer the app to the server and use the deployment script I can't see pages that make calls to the database. The error log show ('1046, No database selected').

Can someone walk me through how to properly deploy the app in 2.3.1. I've used verison 1x in the past and had no problems, but it's been a long time since I've done this.

Thanks.
