Kris, my picture is that I work with Apache OpenJPA - an object-
relational mapper. OpenJPA checks whether generated keys are supported
by calling DatabaseMetaData.supportsGetGeneratedKeys(). If true, the
generated keys are retrieved from PreparedStatement by giving column
names. If false, a second query is executed to get the value of
sequence associated with serial column. So, in the OpenJPA context,
supportsGetGeneratedKeys returning true would be more helpful, but I
can also imagine a case where it would break things.
