Explain IS NOT NULL operator in SQL?

Programming Language
#1

The IS NOT NULL condition is used in SQL to test for a non-NULL value. It returns TRUE if a non-NULL value is found, otherwise, it returns FALSE. It can be used in a SELECT, INSERT, UPDATE, or DELETE statement.

Syntax:

SELECT
Column

(s)
FROM

table_name
WHERE
Column
IS
NOT
NULL
;

In the syntax above the column values that are not null will be filtered for the result.
