Answer / prathiba
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

IMPOSSIBLE...!!!!
WE CAN'T COMPARE TWO NULL VALUES
COZ NULL MEANS "THE VALUE IS UNKNOWN";
SO WE CANT COMPARE THE UNKNOWN VALUES....
