Not too sure, but something like SELECT DISTINCT EmailAddress FROM SELECT EmailAddress FROM classroom_access_list UNION SELECT EmailAddress FROM staff Since you don't want the two sets of results to actually key together, a union makes more sense: just append the results of one to the bottom of the other. Then the distinct will find all the unique ones. However.... I just realized that this may count as a subquery too!
