Treehouse Project ReviewerUsing 2 Inner Joins at the same time?
How do I use 2 joins at once? I'm getting a syntax error (Missing Operator).
SELECT Rentals.RentalDate, Rentals.Due, Customers.lastname, Customers.firstname, Media.ItemTitle FROM Rentals INNER JOIN Customers ON Rentals.Customer = Customers.ID INNER JOIN Media ON Rentals.Media = Media.ItemTitle WHERE Date() > Rentals.Due;

Treehouse Project ReviewerIt's a little project I'm working on in Microsoft Access. It's driving me nuts :-P

229,732 PointsJust a wild guess.
Without seeing the challenge, I'm just wondering if that last join should be:
... INNER JOIN Media ON Rentals.Media = Media.ID ...
It would make sense if the Media table were constructed like the Customers table.

Treehouse Project ReviewerI did change it to that. It works with either INNER JOIN but not with Both

Treehouse Project ReviewerIt turns out the MS Access requires Brackets with multiple join statements.
Thank you for helping me work through it!
SELECT Rentals.RentalDate, Rentals.Due, Customers.lastname, Customers.firstname, Media.ItemTitle FROM ((Rentals INNER JOIN Customers ON Rentals.Customer = Customers.ID) INNER JOIN Media ON Rentals.Media = Media.ID) WHERE Date() > Rentals.Due;

229,732 PointsCan you provide a link to the challenge? The query syntax looks good, but perhaps there's some specific requirement of the challenge that is not being met.
