Hi,
I was trying to use this component for a demo and when I tried to check the ERD, the page was throwing the "Error executing query" error. So, I checked on Service Center and it was an error regarding CONCAT on Oracle only allowed 2 params and was being used on multiple.
I fixed the version that I have installed, but you might want to fix this on your end as well :)
I'm using the OutSystems Cloud solution with Platform Server 11.0.614.0 (was missing from the dropdown...) using oracle database 12c.
