Answer / affan shemle
It is absolutely perfect to compare NULL with NULL. It
yields the result NULL. For those who are saying the result
is FALSE they are taking the answer from IF THEN ELSE. In
all the above answers supported by IF Statement there is a
catch. The result of IF is a Boolean. A Boolean can hold
TRUE, FALSE or NULL. So when you compare NULL vs NULL as a
condition of IF THEN, it returns NULL so the controller goes
to ELSE skipping the IF. Makes sense???
