Re: Error while retrieving generated keys

There's plenty of options, for example calling lastval, or using INSERT
RETURNING, or stored procedures. With frameworks, I'm sure you can
usually work-around by configuring the framework properly. A little bit
of googling tells me that you might be able to set
hibernate.jdbc.use_get_generated_keys to false, though not being a
Hibernate user myself I have no idea where to put that.

In any case, it would help a lot if you could write a FAQ entry of
paragraph or two when you find a solution.

The lack of one fairly new JDBC API call hardly makes the whole database
management system a fossil, that's what I'm saying.
