Hi,
Entity beans actually represent one record. So logically they cant be used
to update multiple records.You can user session beans for this purpose. To
further optimise, you can call stored procedures also.

Hi Wenhui,
Yes, in EJB 1.1 CMP you are limited to single-row updates and inserts.
However many vendors have taken liberal optimization initiatives for CMP
2.0, for example, bulking sql loads from ejbFind() within a txn. In the
same grain, I can't see why vendors cannot optimize multiple inserts or
updates within a single transaction to a single bulk-call; perhaps some
vendors have already done this!
However, if you do/can not rely on vendor-specific bulk updates/inserts,
then JDBC/SessionBean is your only alternative. Simply put, entity beans
are not designed for bulk updates/inserts!

Subject: About Entity Bean's batch updating capability
Hi Dear All,
According to the specification of EJB 1.1, Entity Bean can only
update/insert one record at one call.
If I wanted to update a batch of records at one call(for performance), I
would have to implement
specific method or employ Session Bean.
Am I missing something or are there any other approaches?
Cheers,
Wenhui
