Does anyone know how to write a gateway script on a update from a database to write to a memory tag?

I’m not sure I understand your question. What’s writing to the memory tag? That can trigger a tag event or a tag change event script, which can then compute some update to your DB.

You’ll have to repeatedly query the database to obtain any new information. Look at [Query tags](https://www.inductiveuniversity.com/video/creating-query-tags) – you should be able to use an event triggered by one of those.
