Hi @mike-seekwell
Thanks for really helpful scripts.
In my case, I want to retrieve only 1 certain table in database. How should I edit the code?
Thanks again Mike.

Hi, Thanks for the script - We secure our db by whitelisting ips - do you know where I can find which ips to whitelist to make this work?
