won't even compile. Because you can't assign null to a primitive type

1. Why does int pop = 0 == 0 ? 1 : null; even compile?
Maybe the compiler figures out that it's the same as pop = 1 so it
discards the null? Seems like it shouldn't compile.
It even compiles if the contitional isn't a constant expression - most
odd...
2. How *do* you return a database NULL from a function with a
primitive type as the return type? String isn't a primitive type.
You need to use the corresponding object type, in this case
java.lang.Integer as the return type.
I guessed that might be the case, but haven't had chance to try it -
thanks for the confirmation.
