How about this approach: Create a temporary table (no constraints) CREATE TEMP TABLE temptable AS
(SELECT* FROM tablename LIMIT 1); DELETE FROM temptable; Copy all data into the temporary table
COPYtemptable FROM 'filepath'; Select from the temporary table all items that satisfy the constraints, insert
theminto the real table and delete them from the temporary table: BEGIN; INSERT INTO tablename
(SELECT* FROM temptable WHERE ...); DELETE FROM temptable WHERE ...; COMMIT; All good data should now
bein place. The temporary table should now contain only those items that do not satisfy the constraints for the
realtable.
