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.
