Need some help coming up with a query to show scheduling conflicts for referees.
Basically I need to show games for referees in which the games overlap.
The tables give us the game start times & game length in minutes.
I've simplified the table structure in the attached mdb file
The query below shows the relationship between the tables.
SELECT Persons.PersonId, Persons.NameLast, Persons.NameFirst, Games.GameId, Games.GameNo, Games.GameStartDt, Divisions.GameLength, OfficialPositions.OfficialPositionId, OfficialPositions.PositionName, Divisions.DivisionId, Divisions.DivisionName
FROM Persons INNER JOIN ((Divisions INNER JOIN OfficialPositions ON Divisions.DivisionId = OfficialPositions.DivisionId) INNER JOIN (Games INNER JOIN Games2Persons ON Games.GameId = Games2Persons.GameId) ON OfficialPositions.OfficialPositionId = Games2Persons.OfficialPositionId) ON Persons.PersonId = Games2Persons.PersonId
ORDER BY Persons.PersonId, Games.GameStartDt;
