Philip Ogren commented on DERBY-4921:
-------------------------------------
If you change the client driver to behave as the embedded driver as you suggest
above, then it will not be possible for my example code to work with both the
Derby driver and the PostgreSQL driver without adding a driver-specific
conditional. Please note Knut's observation about PostgreSQL above. It would
be much preferable to me to see the embedded driver behave like the client
driver because that will be much less likely break other people's code
(including mine.)

> Statement.executeUpdate(insertSql, int[] columnIndexes) and
> Statement/executeUpdate(insertSql,Statement.RETURN_GENERATED_KEYS) does
> work, Statement.executeUpdate(String sql, String[] columnNames) doesn't.
