How to Identify Users with Today's Birthdays Using MySQL

Determining if today is a user's birthday using MySQL involves finding all rows where the birthday matches today's date. This can be achieved through a simple MySQL query that compares the birthday, stored as a UNIX timestamp, to today's date.

Here's a SQL query that will fetch all users who have birthdays today:

<pre> SELECT *

  FROM USERS
  WHERE
     DATE_FORMAT(FROM_UNIXTIME(birthDate),'%m-%d') = DATE_FORMAT(NOW(),'%m-%d')

</pre>

The query employs the DATE_FORMAT function to extract the month and day from the birthdate (stored as a UNIX timestamp) and today's date (NOW()). By comparing these values, it identifies users whose birthdate matches today's date.

Once the users are identified, their data can be extracted and used to trigger automated birthday emails or other targeted communication. This query provides a straightforward approach to identify users with today's birthdays from a MySQL database.
