Question
What statements are true about null values? Multiple answers are possible.1 pointA null value indicates the absence of a value. A null value may mean that the actual value is unknown. A null value may mean that actual value does not apply to the specified row. A null value indicates a default value.
Solution
The following statements are true about null values:
- A null value indicates the absence of a value.
- A null value may mean that the actual value is unknown.
- A null value may mean that actual value does not apply to the specified row.
However, the statement "A null value indicates a default value" is not necessarily true. A null value is not the same as a default value. A default value is a value that is used when no other value has been specified, while a null value indicates that no value has been assigned, is applicable, or is known.
