oracle database trigger and INSERT problem [message #545313]

Hi,

I do my first steps with eclipselink as JPA implementation in glassfish and I encountered a problem related to a trigger.

I have a table called TRACE in an oracle DB which I fill with JPA. As long as I have no trigger on this table all is fine. In particular I can INSERT records.

But when I enable a "BEFORE INSERT" trigger which fills a day_of_month field by a date (trace_date) inserted I get no error in log-file but the recods is not persisted in the database.

Entity Trace:
...
@Column(nullable = true)
@Temporal(TemporalType.TIMESTAMP)
private Date trace_date;
...
@Column(nullable = true)
private Byte day_of_month;
...

Trigger:
CREATE OR REPLACE TRIGGER TRACE_I_TR
BEFORE INSERT
ON cobra.trace
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
DECLARE
v_id number;
BEGIN
:new.day_of_month:= to_number(to_char(:new.trace_date,'DD'));
END;
/

What should I do to enable coexistence between database triggers and JPA?

Are you sure your trigger is valid?

Can you insert through raw SQL, or raw JDBC?

Enable logging and ensure the SQL is sent, and the transaction is committed.

Hi , thank you. The trigger was valid bit it was really my fault. The SELECT I checked the result was simply wrong Sad
