What will be the output of the following MySQL statement "NOT (Null)"?

A. True

B. Null

C. False

D. None of the mentioned

Answer: Option B

Solution (By Examveda Team)

This question is asking about how MySQL handles the "NOT" operator when used with the "NULL" value.
Here's the breakdown:
* NULL: In MySQL, NULL represents an unknown or missing value. It's not the same as 0 or an empty string.
* NOT Operator: This operator negates the value of what follows it.

Now, when you use "NOT (NULL)" in MySQL, it doesn't evaluate to "True" or "False" directly. MySQL treats "NULL" in a special way when it comes to comparisons. It generally returns "NULL" for comparisons involving NULL.

Therefore, the correct answer is Option B: Null.

In simpler terms, "NOT (NULL)" essentially means "not unknown." Since we don't know what NULL actually is, we can't definitively say it's "not something." This is why the result remains "NULL."
