From "Using SQLite" ( http://oreilly.com/catalog/9780596521196/ ), page 355: The last way to define the test group is by providing a table name. The table must consist of only a single column. You cannot provide a table and column, it must be a single-column table. This final style is most frequently used with temporary tables. If you need to execute the same test multiple times, it can be more efficient to build a temporary table (for example, with CREATE TEMP TABLE...AS SELECT), and use it over and over, rather than using a subquery as part of the IN operator. -j -- Jay A.
