Creating Placeholders for Subprograms
Another significant application of the Null statement is creating placeholders within subprograms. For instance, when defining a procedure or function body, placeholders might be needed:
CREATE OR REPLACE PROCEDURE myProcedure AS
BEGIN
-- Perform some tasks
NULL; -- Placeholder for future functionality
-- Continue with more tasks
END;
In this case, the Null statement serves as a placeholder for potential future modifications or additions to the subprogram’s logic, allowing developers to structure code architecture more effectively.
