I need to encapsulate, what are basically 2 related function calls into a single

y current thinking is to return a 2 row table with the 2 dates in it. But, I seem to
be having issues getting this to work.

Is it possible for a function to return a table with results from multiple
queries?

You could just return a tuple VALUES(a, b). Or you could define a type to return if you want to get fancy.
Here I you might want VALUE(array[‘heading1’,a], array[‘heading2',b]) unless you’re certain you know which date is which.
