EqualNullSafe

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.

attribute

of the column to be evaluated; dots are used as separators for nested columns. If any part of the names contains dots, it is quoted to avoid confusion.
