#2 - t.term = f.term SELECT m.term AS term, m.definition AS definition FROM (SELECT t.term, e.definition FROM Terms_content t INNER JOIN Favorites f ON t.term = f.term LEFT JOIN TermEntries te ON te.termid = t.docid LEFT JOIN Entries e ON e.docid = te.entryid) AS m LEFT JOIN Favorites f ON f.term = m.term Here the Terms_content table is big, maybe 300k rows, while the Favorites table is small, <100 rows. Query #1 takes 300 ms, and query #2 takes 30 ms. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
