@oscard - In the interim between my original post and your reply I was able to resolve the original certificate issue with the Azure support team that necessitated my customizing the connection string.I unfortunately no longer have a suitable database that would let me test your suggestion,so I'm not able to confirm it would work.However,I believe it would given I used this very same solution in a different tool.
Thank you for taking the time to respond!
Have you tried the Writer JDBC?
It has a parameter for the connection string.Maybe it allows you to concatenate there the "trustServerCertificate=True" option.
