subselect doesnt work

[Daniel Rossi]

hi there, i am trying to remove values from a list menu if the join table
doesnt have keys when a key is selected for instance:
locations
locationID

locations_join
locationID shotlistID

SELECT SQL_NO_CACHE l.locationID , l.location FROM locations l LEFT JOIN
locations_join lj ON l.locationID = lj.locationID WHERE l.locationID NOT IN
(select locationID FROM locations_join WHERE shotlistID IN (5069)) ORDER BY
l.location ASC

so when shotlistID is selected all the keys from the locations_join joined
to the shotlistID would be remove from the locations list please help, i'm
trying to do this in one query saving from getting all the keys into an
array then checking if the values arent in the array when generating the
list.
