- static DataTypes.NULL() pyflink.table.types.NullType [source]#
Data type for representing untyped null (None) values. A null type has no other value except null (None), thus, it can be cast to any nullable type.
This type helps in representing unknown types in API calls that use a null (None) literal as well as bridging to formats such as JSON or Avro that define such a type as well.
The null type is an extension to the SQL standard.
NullType is still not supported yet.
