mySQL SELECT anstehende Geburtstage

Um alle Geburtstage in den nächsten 7 Tagen zu erhalten, addieren Sie die Jahresdifferenz zwischen dem Geburtsdatum und dem heutigen Tag zum Geburtsdatum und finden Sie dann heraus, ob es in die nächsten 7 Tage fällt.

SELECT * 
FROM  persons 
WHERE  DATE_ADD(birthday, 
                INTERVAL YEAR(CURDATE())-YEAR(birthday)
                         + IF(DAYOFYEAR(CURDATE()) > DAYOFYEAR(birthday),1,0)
                YEAR)  
            BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 7 DAY);

Wenn Sie die heutigen Geburtstage ausschließen möchten, ändern Sie einfach > zu >=

SELECT * 
FROM  persons 
WHERE  DATE_ADD(birthday, 
                INTERVAL YEAR(CURDATE())-YEAR(birthday)
                         + IF(DAYOFYEAR(CURDATE()) >= DAYOFYEAR(birthday),1,0)
                YEAR)  
            BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 7 DAY);

-- Same as above query with another way to exclude today's birthdays 
SELECT * 
FROM  persons 
WHERE  DATE_ADD(birthday, 
                INTERVAL YEAR(CURDATE())-YEAR(birthday)
                         + IF(DAYOFYEAR(CURDATE()) > DAYOFYEAR(birthday),1,0)
                YEAR) 
            BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 7 DAY)
     AND DATE_ADD(birthday, INTERVAL YEAR(CURDATE())-YEAR(birthday) YEAR) <> CURDATE();

                YEAR) 
            BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 7 DAY)
     AND (MONTH(birthday) <> MONTH(CURDATE()) OR DAY(birthday) <> DAY(CURDATE()));
