Are you talking about the fields, or the buffer? A pointer to the memory cannot be in the buffer passed to write_row, so is the blob stored in the buffer verbatum? > When returning a row, you need to allocate a memory buffer > in your engine to store the blob and return the pointer to the > blob in the row. Ok, but what about update_row? Is there a flag somewhere that tells me whether the blob has changed (in which case I would have to store the new version)? > Hope that helps Thanks, it does.
