BDE can't read part of the blob. DB2 allows it through CLI. Also it allows
put it directly to file. Is there somewhere header files? Can I get from
BDE handle needed for CLI?

Are you using the BDE calls ?

 Dataset.updatecursorpos;
 check(dbiOpenBlob(Dataset.handle, Dataset.activebuffer,
Dataset.fieldbyname(FieldName).fieldNo, dbiReadOnly));
 try
  check(dbiGetBlobSize(Dataset.Handle, Dataset.ActiveBuffer,
Dataset.fieldbyname(FieldName).FieldNo,BufferSize));
  if BufferSize < 1 then
  begin
   Buffer := nil;
   BufferSize := -1;
   exit;
  end;
  inc(buffersize);
  if Get_buffer(Buffer, Buffersize) then
   check(dbiGetBlob(Dataset.Handle, Dataset.ActiveBuffer,
Datset.fieldbyname(FieldName).FieldNo , 0, BufferSize-1, buffer,
result_size));

finally
  Check(dbiFreeBlob(Dataset.handle, Dataset.ActiveBuffer,
Dataset.fieldbyname(FieldName).FieldNo));
end;

That doesn't work. BDE load whole blob on dbiOpenBlob (!), so you can't
choose part of the blob. More, BDE retrieves by 8k (very slow), and after
~25M DB2 v5 generates an error, so by far its impossible to work wiyh large
blobs!
(I inserted your code exactly in my code, but...)
