I still don't understand your strategy above. Where am I, the user, supposed to get the "hex byte after byte linear dump" from? Imagine, I have a photograph of you called jcd.jpg sitting on my hard disk at ~/pics/jcd.jpg and I want to insert it as a blob into CREATE TABLE pics (id INTEGER PRIMARY KEY, pic BLOB); via the sqlite3 shell. Could you please give me a step by step on how to do that? Not via a small program written in a programming language, but only via the sqlite3 shell, as both you and I agree that was the implied intent of the OP's question. > BTW, having images stored > direct in hex blobs without any convoluted encoding allows smart > database managers to display the images directly in resultset grid, > which I find very convenient. > > I didn't mean to enforce this as a convenient way to handle routine > operation, except if the particular situation demands it.
