Sorry, I just realized I didn't make the optimization explicitly obvious... when I say "Select the children" I mean to select them using an IN( id1, id2, id3 ) clause instead of a query for each. This is why we build the array of parent IDs (also I wrote build an array of "child IDs", it should have read "parent IDs" and has been fixed above :). [/snip]SELECT DISTINCT children FROM table WHERE column1 IN(id1, id2, id3....) ? I am sure I am not following you now. Maybe I didn't explain clearly?
