Php MySql birthday query between dates ignoring year

Question

I am trying to get upcoming birthdays from a database so I can create a mailing list for those customers. $pet_bdate - The admin supplies a date with JQuery datepicker in the format dateFormat: 'yy-mm-dd'. $plus_days - He can also choose For Dates Range - Plus Days from Chosen Date from 0 to 14.

Server config: Php v 5.2.17 MySQL v 5.5.23 (So several more advanced Php functions don't work as well as MySql)

The column petbday is of type DATE .

Here is the query:

SELECT * FROM `customer` c LEFT JOIN `pet` p ON (c.customer_id = p.customer_id) 
WHERE (DATE_FORMAT(p.petbday, '%m-%d') 
BETWEEN DATE_FORMAT(2014-04-13, '%m-%d') AND DATE_FORMAT(DATE_ADD(2014-04-13, INTERVAL 7 DAY), '%m-%d')) 
GROUP BY c.customer_id ORDER BY firstname, lastname, email

And here is the Php code that makes it:

SELECT * FROM `" . DB_PREFIX . "customer` c LEFT JOIN `" . DB_PREFIX . "pet` p ON (c.customer_id = p.customer_id) 
WHERE (DATE_FORMAT(p.petbday, '%m-%d') BETWEEN DATE_FORMAT(" . $pet_bdate . ", '%m-%d') AND DATE_FORMAT(DATE_ADD(" . $pet_bdate . ", INTERVAL " . $plus_days . " DAY), '%m-%d')) GROUP BY c.customer_id ORDER BY firstname, lastname, email

This query returns ZERO rows for a date that has birthdays in the DB.

How can I hand a formatted date to query so to ignore year?

I tried formating it prior to handing it to query but when it comes to calculating dates with Php I got a little mixed up.

Any suggestions on how to resolve this?

Answer 1

Try using DAYOFYEAR instead of string comparison.

Update: I also need to add that your dates should be wrapped in colons to work properly '2004-04-15'.

Answer 2

This is my solution:

SELECT * FROM `customer` c LEFT JOIN `" . DB_PREFIX . "pet` p 
ON (c.customer_id = p.customer_id) 
WHERE (DAYOFYEAR(p.petbday) BETWEEN (DAYOFYEAR('" . $pet_bdate . "')) 
AND (DAYOFYEAR(DATE_ADD('" . $pet_bdate . "', INTERVAL " . $plus_days . " DAY))))
GROUP BY c.customer_id ORDER BY firstname, lastname, email

So in order to get DATE RANGE I used DAYOFYEAR (as andig suggested) on the column itself p.petbday and on both range dates:

$pet_bdate - ORIGINAL STARTING DATE
DATE_ADD('" . $pet_bdate . "', INTERVAL " . $plus_days . " DAY) - ORIGINAL 
STARTING DATE PLUS INTERVAL DAYS

I used DATE_ADD because my MySQL version is v5.5.23

NOTE: Both dates need to be passed as string (hence the single quotes).

Hope you found this useful...

  $('input[name="pet_bdate"]').datepicker({
        dateFormat: 'yy-mm-dd',
        yearRange: '2000:2000', // one year - leap year
        changeMonth: true,
        changeYear: false, // NO **Year** drop down box
        numberOfMonths: 1,
        minDate: new Date('2000/01/01'), // START date
        maxDate: new Date('2000/12/31'), // END date
    beforeShow: function(input, instance) {
      var firstDate = new Date('2000/01/01');
            if (this.val != 0) {
              $('input[name="pet_bdate"]').datepicker( 'setDate' , $('input[name="pet_bdate"]').val());
            } else {
              $('input[name="pet_bdate"]"]').datepicker('setDate', firstDate);
            }
    }
    });
  $('#ui-datepicker-div').removeClass('ui-helper-hidden-accessible');
