CROSS JOIN and virtual tables in SQLite. Learned today on the SQLite forums that the SQLite CROSS JOIN in SQLite is a special case of join where the provided table order is preserved when executing the join. This is useful for advanced cases where you might want to use a SQLite virtual table to perform some kind of custom operation—searching against an external search engine for example—and then join the results back against other tables in a predictable way.
