[Opensource] usage of DBObject.delete() (4.02)

[Mike Traum]

I see. I assume this javadoc is in 4.1 because it is not in 4.02. I'll bring
that up in a new message because it opens many concerns about expresso
development that I have...

Thanks,
Mike

you want "deleteAll()"

the javadoc for delete() already specifically mentions as that the key for
the object is use:

     * Delete this record from the target table. The current field values
for the key
     * of this object tell us which record to delete. This default version
     * of delete also deletes associated detail records (e.g. performs a
     * "cascading delete" of details.

I added the following ref:

         *
         * @see DeleteAll to delete objects identified by non-key fields


why?  I suppose the reason is that the SQL statement using just the keys is
very small and efficient.  Using the values of all fields is relatively
expensive.
