Database Developer Interview Question:
Tell us how to Test for NULL Values?
Submitted by: MuhammadA field with a NULL value is a field with no value. NULL value cannot be compared with other NULL values. Hence, It is not possible to test for NULL values with comparison operators, such as =, <, or <>. For this, we have to use the IS NULL and IS NOT NULL operators.
