People commonly believe that doing so must be easy. I certainly get a lot of requests for it from people who think they know how. But in fact, row-level locking is extraordinarily difficult. To my knowledge, nobody has yet come up with a way to do it unless you: * Add a server process to coordinate access. * Accept that the database might be corrupted if an application crashes while writing. * Make writing to the database very, very slow. * Double the size of the database file. If you think you know a way to implement row-level locking that does not impose one of the above limitations, then please tell me and I will look into the matter. -- D.
