Hi -

Is there a workaround to be able to lookup or build some sort of relation table with Postgres and a Glide Table? Is there a work around anyone has?

Kind Regards

Is your relation a single or multiple relation?  
It should work for a single relation, I believe.

Oh, wait. It’s a query. Try using a single value column instead of a lookup.

Thank you!! That seemed to work. Single Value.

Yeah. I haven’t used SQL data sources with Glide yet, but I believe that many of the same limitations that apply with Glide Big Tables also apply. One of those is that you can’t do a lookup through a multiple relation or query. If you’re just wanting a specific value (as opposed to an array), then a single value is the way to go.

Thanks Darren. Yeah, learning the limitations as well, but glad to see there was a workaround! Appreciate the help and quick response
