Hello Nick,
I sincerely apologize for the delay here. Hopefully I can help provide the information you need and/or set you in the right direction. You are correct that OracleDB is not supported out-of-the-box with the ODBC Query app. However, it is possible to configure. The ODBC query app depends on unixODBC and a corresponding driver for each supported flavor of database. If you wish to work with a database that is not initially supported, you will need to install the driver for that database and update the `sql_connection_string` value in your app.config file accordingly.
This is a more straightforward process on an integration server than AppHost. It sounds like you are running AppHost, so in your case this would mean a change to the application image (container) to install and configure additional ODBC drivers in order to successfully use them in your connection string.
Sorry for the long-winded answer, but hopefully that at least gives you a better idea of what you would need to configure to get Oracle running. You are welcome to submit an RFE to the team regarding this as well.
