My question is: shouldn't sqlite's engine figure out what I am trying to do and sort the tables on the fly in an effort to optimize the query? When using no indexes, a .explain reveals 3 nested loops which take a long time to return results.

Any help/ideas will be much appreciated.



You should read the optimizer docs at http://www.sqlite.org/optoverview.html for an explanation of why this happens.
