You can get from the database the actual
type defined in the database for that column
right ? (so if it's BIT your driver can tell it's
BIT in the database, I presume).
So then, as per the JDBC spec
1) while retrieving:
convert that BIT (however long it may be) into a
boolean [true, say, it it's all 1's else false].
2) while saving:
convert java true to a '1' and save that as a BIT
(convert java false to '0').
That's what the spec suggests from what I can
tell. Of course, you could also convert the
BIT into a string if the user wants it as a string).
Best regards,
