Has anyone done something like this to connect Appsheet with an on premise SQL db?
Can you connect to our corporate database or resources behind a firewall? Not directly. The AppSheet architecture permits our service to interact with data sources via a web service that acts as a proxy to the actual data. If the actual data is behind a firewall, you (or your IT department) will need to create a web service that acts as a proxy for the data. This is a relatively straightforward task for a web developer, and we can help enterprise customers with sample code for this proxy service.
