MySQL - Where relation exists add a where, ignore where if not exists

QUESTION

MySQL - Where relation exists add a where, ignore where if not exists

Asked 2017-Sep-06 at 09:15

I have a flights table and a bookings table.

Flights has a column, max_passengers

Flights have bookings in way of the bookings table referencing a the flight_id

I am using this in laravel / PHP but I am looking help with the actual SQL because its driving me a bit loopy I can currently query a flight and work out the number of free places left by using sum(bookings.places_booked) then sumtracting this number from the max_passengers but how could I write SQL that does:

Randomly selects flight
If bookings are against this flight sum the amount of places booked and add a where < max_passengers

I can do this part but how can you make it so if no bookings are made against a flight the join / where becomes optional and doesn't matter because the max_passengers would be the number of free places.

I had thought about adding a free_places column to the flights table but it would come with issues which the current setup avoids.

Two things :
1) You should use the HAVING clause and not the WHERE clause for aggregation functions (your query should throw an error).

2) Use COALESCE() to replace the value from NULL to an actual value. This is the second reason why your query is not working. When there is no match , bookings.places_booked is null , then the condition is rendered as NULL < flights.max_passenger , which will always be false.
