Question

How can my InnoDB table increment 5 instead 1 in each entry ID?

Thanks

ID - TITLE
5  - Entry 1
10 - Entry 2
15 - Entra 3

Answer 1

How about using a TRIGGER on the table? Something similar to this code:

DELIMITER $$

CREATE TRIGGER ai_increaseByFive AFTER INSERT ON tbl
  FOR EACH ROW BEGIN
    UPDATE tbl SET id = (id - 1) + 5 WHERE title = NEW.title;
  END;
$$

DELIMITER ;
