Re: Basic Query Question

i'm not sure but i think not being explicit about the join causes psql
to try to join on ID.

What are you getting? an error or an empty result set?

I would think you should do the join explicitly like this:

select bike.bike_id from bike  join booking on bike.bike_id =
booking.bike_id where booking.date != '2011-11-20'
