Hi,

This is a quick implementation of solution 2, for those who really
need it quickly (sorry for attaching a file on a mailing list...) Just
replace FBBlobField with this one, but THIS IS NOT AN OFFICIAL
SOLUTION!

So the little problem with this solution is it starts a new
transaction for every blob, and surely it won't make things faster ;(

Well, meanwhile I came up another possible solution:
would that be correct to finish the transaction after one of the
following:
- the connection is closed
- after new statement/preparedStatement is created
- after executeUpdate/executeQuery is called again

Best wishes,
Daniel
