RE: Methods of calling stored procedures in OJB
Ron, My doubt was how was the stored procedure being called? I was thinking that you had to actually call it in your java code. However, I think what you and the documentation are implicitly saying is that the broker is actually calling the stored procedure as you have configured it in the repository. Therefore there is no need to call the stored procedure in one's java code. When I pass an object defined to use a stored procedure to the OJB store instruction the s.p. will be executed. Does this sound correct? Thanks, Jim Wright -Original Message- From: Ron Gallagher [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 08, 2006 8:44 PM To: OJB Users List Subject: Re: Methods of calling stored procedures in OJB Jim -- OJB supports the use of stored procedures to handle all persistence operations (insert, update and delete). The stored procedures that are configured in the repository are used in place of standard insert, update and delete SQL commands. You do not need to use any sort of database triggers in order to take advantage of OJB's use of stored procedures for persistence operations.

That requirement was accomplished via the insert/update triggers that are referenced in the sample.

This requirement was accomplished in two steps: (1) the stored procedures that OJB utilized returned these values to the caller (i.e. OJB) via the "RETURNING" clause and (2) the configuration of the stored procedure in the repository file included the attri bute 'return="true"' attribute on any arguments that were returned to OJB. I hope this helps you out. Let me know if I can clarify things any further.

Re: Methods of calling stored procedures in OJB
Jim -- OJB supports the use of stored procedures to handle all persistence operations (insert, update and delete). The stored procedures that are configured in the repository are used in place of standard insert, update and delete SQL commands. You do not need to use any sort of database triggers in order to take advantage of OJB's use of stored procedures for persistence operations. The example that you refer in the documentation to was culled from an application that I was one of the lead architects on. In the environment that that application was to be deployed in, the DBAs insisted that all persistence operations be performed by stored procedures. This was accomplished by utilizing OJB's support for stored procedures.

Methods of calling stored procedures in OJB
Does one have to use database triggers in order to run stored procedures in OJB? The Apache documentation seems to imply that: http://db.apache.org/ojb/docu/howtos/howto-work-with-stored-procedures.h tml#A+simple+example I need a way to run them that does not involve triggers. Jim Wright
