Thanks guys for all your help.

Steve, I think I've tried what you have suggested without any luck as
well... The statement works fine, but what inserted is not correct...
it seems like only the symbol '?' was inserted into the blob field...

I will try the suggested cxOracle library in place of odbc as a
trial... but I think since 95% of the code is using odbc, it would be
hard to convince the team to chance to the new library... anyway, I
will let you know how it goes.
