Represents SQL NULL value.
Inherited Members
Namespace: Oracle.NoSQL.SDK
Assembly: Oracle.NoSQL.SDK.dll
Syntax
public class NullValue : FieldValue
Remarks
SQL NULL is a special value that is used to indicate the fact that the value of the field is unknown or inapplicable. SQL NULL may be a value of the field of any data type. Note that SQL NULL is distinct from JSON NULL which is a value of JSON type NULL. See JsonNullValue for more information.
The only value of this class is Null, which is the only immutable singleton instance of this class. No other values are instantiated.
When serialized to JSON (see ToJsonString(JsonOutputOptions)), this value becomes null value in JSON, thus indistinguishable from JsonNullValue.
