Ok, well.... very interesting and I'd never have had this idea, but indeed it works: within a transaction, it takes only a few seconds. This is very surprising as to me, a single DELETE statement is nothing more than that: a single atomic operation which should automatically be treated as a transaction (auto-commit-mode). *confused* _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
