U can compare the two null values, by using these operators

IS NULL: operator returns true of column value is NULL.

IS NOT NULL: operator returns true of column value is not
NULL.

<=> operator compare values, which (unlike the = operator)
is true even for two NULL values

WE CAN'T COMPARE TWO NULL VALUES

SO WE CANT COMPARE THE UNKNOWN VALUES....
