Question

I have the following SQL

SELECT CASE
        WHEN B.bookingId = P.bookingId
        THEN 1
        ELSE 0
        END AS PAID
        FROM Booking B
        LEFT OUTER JOIN Payment P ON P.bookingId = B.bookingId

This outputs 3 rows; 1, 1 and 0

I would like to extend this query to output the booking details of the 0 value.

How can I do this?

Thanks

Answer 1

select * from booking
where booking_id not in ( select bookingid from payment )
