Use MySQL to determine whether today is a user's birthday

Question

I have all users' birthdays stored as a UNIXtimestamp and am wanting to send out e-mails each day to users that have a birthday that day.

I need to make a MySQL query that will get all of the rows that contain a birthday on today's date.

It seems like this should be fairly simple, but maybe I am just overcomplicating it.

Answer 1

You can use the query below if date of birth stored in a table.

Today Birthday :

select * from TABLENAME
 where DAY(FIELDNAME) = DAY(CURDATE())
   and MONTH(FIELDNAME) = MONTH(CURDATE());

Yesterday Birthday:

select * from TABLENAME
 where DAY(FIELDNAME) = DAY(DATE_ADD(CURDATE(), INTERVAL -1 DAY))
   and MONTH(FIELDNAME) = MONTH(CURDATE());

Tomorrow Birthday:

select * from TABLENAME
 where DAY(FIELDNAME) = DAY(DATE_ADD(CURDATE(), INTERVAL 1 DAY))
   and MONTH(FIELDNAME) = MONTH(CURDATE());
