  Re: ru compare the 2 null values?
Answer
# 1
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
