All,

I need to do the following:

FinancialAccount table, Position table.

for each account, I want to sum up(position1+position2) all positions.

FinancialAccount FA1

position1=$45.00
position2=$35.00

update FinancialAccount FA1 with a sum of $80.00

Is Hibernate good for this, or just plain JDBC?
Sorry, just started using this.

If that's all you want to: then let the database do this for you. Neither Hibernate nor JDBC are needed for this kind of batch. Why instantiate thousands of Java objects?

Are you talking about triggers and stored procedures?

What ever you want, what ever you need...

Note that you can use native SQL from within a Hibernate session! (this first came into my mind).

I wonder why you say Hibernate is not for this?

It is handy since I am dealing with 4 tables: ) = code generation.
It also simplifies my db code
