Re: Complex Query - Optimization
Robert - this is a pre-coffee suggestion so may not be feasible. But first would be to make sure you have indexes on (day, hour) and (room). Possibly you might want to try removing the DISTINCT from your sub-select - which would obviously increase the number of rooms in the in, but might prevent mysql from having to sort. Although, if you only have 2000 records and it is taking 10 secs, I suspect something else is wrong...
