thma,hi:
OJB is a great project I had never seen in the world.
but a little problem? :-)
When I insert a record which maybe had already been inserted before. in
tradional way
the database will return a Exception such as "The primary Key constrain
violated ".
but in ojb, if I use store method, then the record will be updated if
already in database,
then , should I first query then go to store it ??
this way may be very inefficient.
Then how can I get rid off this inefficient?
Thanks a lot!
xiaxin
