Number precision when using Generic database connection

Hi,

I'm using an Oracle database. I have a "NUMBER" column (no precision, no scale defined).
If I use an Oracle database connection, Kettle will consider this column as TYPE_BIGNUMBER whereas if I use a generic database connection, Kettle will use TYPE_NUMBER.
Would it be possible for Kettle to guess the DB vendor so that the behavior would be the same as when using an Oracle connection?
Regards,
Nicolas
