Resolution: Won't Fix
I agree with what [~charlesbc] described. QueryDatabaseTable is designed to
capture inserted/updated records from a table. "Additional WHERE clauses" might
be useful to filter out records those are out of interest. Or if sub-query is
needed for other reason (JOIN?), then creating a VIEW using the sub-query part,
then use the VIEW from QueryDatabaseTable will be a work-around.
Closing this as "Won't Fix". Please feel free to reopen it if more discussion
is needed.
