Agreed, this question has come up many times recently. Would you like to

write a paragraph or two explaining the situation and the workaround?

 

I don't know about an easy workaround. Especially while using frameworks.

I am using Spring framework with Hibernate mapping and a lot of low level Java code is hidden from me. I do not have a particular desire to go back to plain JDBC calls. If I have to, I'd replace INSERT statement with a call to a stored function returning key value. But as said in my original email it is a lot of additional hassle.

;-) Now you're exaggerating.

Am I? Who, in his right mind will go back from using JPA or Hibernate to plain old JDBC calls?

Should we go to managing transactions manually, OR mapping, etc?

It would be exaggerating if I’d offer to go back to punch cards or coding in assembler. (I do remember it).

Ken Johanson posted a preliminary patch in February, but there was a

bunch of issues with it. This is an open source project, so if you'd

like to see it happen, patches are more than welcome.

I can look up at this patch and see if I can contribute to fix it. Unfortunately I am on tight project schedule.

How do I download the patch, though?
