The name &quot;localhost&quot; always points to the machine that code is run on. In case of Appian, it is the Appian server.</p> <p><a href="https://www.youtube.com/watch?v=MDu6hWknk70">https://www.youtube.com/watch?v=MDu6hWknk70</a></p> <p>You would have to expose your database server to the internet, find that IP address and then you might be able to connect.</p> <p>A warning here: Exposing services to the internet will make them being attacked almost immediately! Do not do this if you do not know what you are doing!</p> <p>An alternative could be to get an account on one of the available database services and connect those.</p><div style="clear:both;"></div>https://community.appian.com/thread/142391?ContentTypeID=1Fri, 01 Nov 2024 15:40:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:3c35be30-0aba-49fe-8a06-56ff8ef0e72bSoma<p>You cannot do that in the Community Edition.</p><div style="clear:both;"></div>https://community.appian.com/thread/142389?ContentTypeID=1Fri, 01 Nov 2024 14:27:35 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:37da6be0-98ce-4390-a790-d2a39b1d0a4bNewBegineer<p>I used Appian Demo Platform</p><div style="clear:both;"></div>https://community.appian.com/thread/142388?ContentTypeID=1Fri, 01 Nov 2024 14:12:53 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:430f4ab4-da40-4688-92d5-56f0a4ba97c8Stefan Helzle<p>I assume that you use the Community Edition.
