Hi Kuon
Use the standard jdbc method on a PreparedStatement, called
setBinaryStream(..) (using version 8.0.x of the driver). The bad thing
is that getting the data out from database using getBinaryStream(..)
will use a lot of memory relative to the filesize - there seems to be no
way to avoid this. Look elsewhere in the archives for an explanation by
Oliver on this issue...
