Allow testing of just an Inner Sub Query.(ISQ)
Currently, you have to make the ISQ the Top Level Query (TLQ), and your current Top Level an ISQ. Doing this deletes the sorting on query that was the top level.
EDIT
Correction… If the original TLQ had any sorting, they must be manually removed. Same for if the ISQ (that you’ve temporarily made the TLQ) has any sorts.
