How to use PL/SQL NULL Statement to Improve Code Readability In SQL
The Null statement proves particularly useful in enhancing code readability and usability. Consider a scenario where a placeholder is required within a block of code, but no specific action is needed to take place:
BEGIN
— Perform certain operations
NULL; — Null statement as a placeholder
— Continue with other operations
END;
By employing the Null statement in such instances, developers can clearly denote sections in the code that require no action, making the code more understandable and readable for other programmers or during future reviews and modifications.
