You can't do that.
I'm sure the reason why is because that would allow a variable with ANY VALUE to appear at runtime, which, if happened, would cause all sorts of garbage data to be read in or even cause the program to try to read memory outside of it's range (which would crash the program).
So, like EpicBoy stated, you have to use a SELECT statement or similar method.
