Thanks Peter and Brent. GROUP_CONCAT does exactly what I want. Brent, you're right, I don't really want to break up the times into separate fields that bad, the results are going into PHP so I can parse the combined fields there without much difficulty. The next problem is how do I use the results in a join. My first thought (that doesn't work) was: SELECT event_id, GROUP_CONCAT( CONCAT(start, '-', end) ) start_end FROM events GROUP BY event_id JOIN event_details WHERE events.event_id=event_details.event_id I have tried brackets, and a few other things, but I haven't got it yet.
