Another thing you can try is declare a second object to the same table... So that in you code you need to check whether you want to use the default values then you use this second object. If you need to fill all columns you use the original object.
I have a table for persons which includes a blob (a photo).. I created several objects mapped to the same table.. one object has all the columns (except photo). another object has pk and photo. some objects only fetch (and save) a subset of data. It works because the layout of my application is such that this is possible.

I guess the possible solution I am seeking for could be to declare something like this: <field-descriptor name="dateChanged" column="DATECH" jdbc-type="DATE" use-database-default-if-null-on-insert-operations = "true" /> Or can I somehow dynamically exclude this field from participating in operation, whatever this operation might be? Similar to ObjectModification class mechanism, but that will exclude this field from operation only for this Broker? I know I can dynamically change the class descriptor and set this field to anonymous and then revert it back to normal, but I am afraid this will impact other Brokers operations with this class, -Sergey -----Original Message----- From: Armin Waibel [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 04, 2004 11:30 AM To: OJB Users List Subject: Re: insert object, and don't specify a value for one of the fields Hi Sergey, Manukyan, Sergey wrote: > Folks, > > The thing is I need to insert a record where for one of the fields I want to > omit value, not specify at all, not even null, nothing.
