The following query uses a set operator (e.g., UNION or UNION ALL) to find participants who either: Completed the 5K race or Are female participants. SELECT P.participantID, P.name, P.age, P.gender, R.distanceCompleted FROM Participants P JOIN Results R ON P.participantID = R.participantID WHERE R.distanceCompleted = ‘5K’ UNION SELECT participantID, name, age, gender, ‘No Race’ FROM Participants WHERE gender = ‘F’; Example Output: ParticipantID Name Age Gender DistanceCompleted 1 Sarah Johnson 25 F 5K 2 Mark Smith 30 M 5K 3 Emily Davis 22 F 5K 4 Lisa White 28 F No Race   This doesn’t get us exactly the data we need.
