> You do not need to use the CASE expression for avoiding NullPointerExceptions when a
> nullable column becomes a method receiver.
> If the value of the instance specified in an instance method invocation is null, the
result of
> the invocation is null (SQL NULL). However, you still might need to use the CASE
> expression for when a nullable column is a primitive method parameter.
