Annotation Type SqlNullable

@Retention(RUNTIME)
@Target({METHOD,PARAMETER})
public @interface SqlNullable

Indicates a parameter or return value can be NULL.

@SqlNullable annotation, when placed on a parameter of a ScalarFunction or ScalarOperator method, indicates that the method should be called also when the parameter is NULL. In the absence of @SqlNullable annotation, the engine assumes the implemented SQL function or operator is supposed to return NULL when given parameter is NULL and does not call the implementing method.

@SqlNullable placed on a ScalarFunction method indicates that the implementation may return NULL.
