Since it is not possible to test for the NULL values with the comparison operators(=, <, >), we can use IS NULL and IS NOT NULL operators instead.

Syntax:

--Syntax for IS NULL

SELECT column_names
FROM table_name
WHERE column_name IS NULL;

--Syntax for IS NOT NULL

SELECT column_names
FROM table_name
WHERE column_name IS NOT NULL;
