Hi
I think that the problem can be solved outside ODBC related to BLOB upload, relying only on API.
I've searched the C++ API and there are some usable functions. isc_create_blob2(), isc_put_segment(), isc_close_blob() which can be used to create a BLOB space in database and write into it. Then , given the BLOB_ID returned by the first function, all is needed is to execute an update statement to set the BLOB column to this BLOB_ID (at least this is what I read there)

As I'm interested and I'm somehow familiar with how API works, I'll try to expand my Firebird API wrapper class with this functionality. If I succed, I'll post an updated version or I'll send you the class by e-mail.

Cheers.
