case class EqualNullSafe(attribute: String, value: Any) extends Filter with Product with Serializable
Performs equality comparison, similar to EqualTo. However, this differs from EqualTo
in that it returns true (rather than NULL) if both inputs are NULL, and false
(rather than NULL) if one of the input is NULL and the other is not NULL.
