Any examples of successful SQL Queries using DB Connector?

I’m having some problems with my SQL DB connector, I’m trying to connect my app to a SQL on AWS and having problems. Here’s the full story.

I can create SQL queries, but can’t get them to work in bubble.

I wanted to know if anyone could share successful queries that they’ve built to connect with a SQL database? I’m looking for clues on how to structure them.

Thanks!

Anyone?
