In SQL Server, NULL represents an unknown or missing value. When a comparison operation is performed between a non-NULL value and a NULL value, the result is always NULL. This is because the comparison cannot determine the relationship between the non-NULL value and the unknown/missing value represented by NULL. Therefore, when a comparison is made with a NULL date, the result is always NULL.
