Hi guys, I want to know, does mysql have a problem if you update a value in the db to its current value? Will it just ignore or overwrite? Thanks, -Tony
It has no problem. Whether it will ignore or overwrite is the kind of thing most SQL programmers don't worry about - the db engine is a black box. We give it certain input and it gives us certain output. How it does that might even change from version to version. We don't care. That sort of thing only comes in if you're the one writing the code for the engine.
