SELECT and have the SELECT part > produce an empty resultset. It simply does nothing. Sorry, I should have been more explicit in what we are doing. The select will return results because we do not want to delete the data from the temporary table (that involves a write and fsyncing). However, I think I've come up with a solution: CREATE TRIGGER .... BEGIN INSERT OR REPLACE INTO temp_table SELECT * FROM table_view WHERE <the data is currently not in temp table> AND <which record you want copied>;
UPDATE temp_table SET ...; END; This works since the UNION will select entries from the temp table first, and ignore those in the permanent table that have the same primary key (that is, assuming I understand UNION properly). I'm also making the assumption that it is valid to query the view that the trigger is running on. Is this a sound approach?
