1) You are opening a different file than the one you think you are opening.
E.g. you are using a relative path to the file, and the workding directory is
not what you expect it to be.
2) You are starting an explicit transaction (see BEGIN) and forgetting to
commit it.
3) You are starting
As Simon said use substr() to get first character and use cast(X'FF'
as text) to convert some hexadecimal character code to symbol (in my
example the code is FF = 255). But there's no way to convert character
into its code, so you cannot do any arithmetics with it though you
probably don't need it
Hi Pavel,
Thanks a lot. You are right. I missed out a sqlite3_finalize() and that
prevented the commit.

if sqlite is telling you that the table doesn't exist, the .schema command

Hello!
See
http://mobigroup.ru/files/sqlite-ext/murmurhash/
and a few words on russian
http://geomapx.blogspot.com/2009/12/murmurhash-20.html
The examples:
select murmurhash(1,2,3);
1074609160
sqlite select murmurhash('hello',99);
3350841100
sqlite select murmurhash('hi!',1);

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.
Sorry, I'm no vxWorks, Unix, Linux, MacOS, Windows, AS400, Symbian,
As others have said, there are lots of ways to store the image data directly
in the DB with BLOBs, encoding, etc. Alternatively, you could store the
pics separate from the DB and just store the path to the pic file in the DB.
