Feb 12, 2013 at 19:42 comment added Nico alright, i got your point. in case of intersecting intervals in one table, results got mad. will check this.
Feb 12, 2013 at 19:31 comment added Nico I checked this out again, see this fiddle which has completely overlapping intervals in all three tables. it returns correct results, as i can see. could you provide a case in which wrong results are returned? feel free to adjust demo data in fiddle!
Feb 12, 2013 at 16:04 comment added ErikE I have another idea I haven't had time to get working. For what it's worth, your query returns wrong results with overlapping ranges in all tables.
Feb 12, 2013 at 15:23 comment added Nico Runtime is definetely much higher than 1st approach. I had no time to check if further indices may decrease it yet. Will check as soon as possible!
