Our JDBC driver (and the SQL Interface) is read only. I could suggest the possibility of using another driver, such as Java as that would give you write capabilities, but then you’d lose the SQL aspect for your users. I’m sorry you spent so much time proving this out to find JDBC and the SQL Interface is read only. We do have it stated on the docs, but I will try to make this note stand out more: Query with Atlas SQL - Atlas - MongoDB Docs
