Tente isto:
DROP PROCEDURE IF EXISTS filldates;
DELIMITER |
CREATE PROCEDURE filldates(dateStart DATE, dateEnd DATE)
BEGIN
WHILE dateStart <= dateEnd DO
INSERT INTO tablename (_date) VALUES (dateStart);
SET dateStart = date_add(dateStart, INTERVAL 1 DAY);
END WHILE;
END;
|
DELIMITER ;
CALL filldates('2011-01-01','2011-12-31');
Aqui está o SQL Fiddle para brincar com ele:http://sqlfiddle.com/#!2/ 65d13/1
EDITAR (para verificar se a data já existe), conforme solicitado por Andrew Fox .
CREATE PROCEDURE filldates(dateStart DATE, dateEnd DATE)
BEGIN
DECLARE adate date;
WHILE dateStart <= dateEnd DO
SET adate = (SELECT mydate FROM MyDates WHERE mydate = dateStart);
IF adate IS NULL THEN BEGIN
INSERT INTO MyDates (mydate) VALUES (dateStart);
END; END IF;
SET dateStart = date_add(dateStart, INTERVAL 1 DAY);
END WHILE;
END;//
