如何在MySQL中按月获取记录?

I have stored Date in database in dd-mm-yy format, for example 03-10-2013,

How to search record by month? Month in digit (01 to 12);

I am using currently

$query = "SELECT * FROM data  WHERE date LIKE %$month%";

but this not working properly.

    Fix the date format in your database structure first, change it to: yyyy-mm-dd

    Then change your query statement to:

    $query = "SELECT * FROM data WHERE MONTH(`date`) = '$month';
    

    This will select the month as '5' or '11' or '12' which will give duplicates for differing years.

    If you need the month with year (to avoid duplicate years):

    $query = "SELECT * FROM data WHERE SUBSTR(DATE(`date`),1,7) = SUBSTR(DATE('$month'),1,7);
    

    This will return: '2015-01' or '2014-12'

    To get date as '01' or '04' or '12':

    $query = "SELECT * FROM data WHERE SUBSTR(DATE(`date`),6,2) = SUBSTR(DATE('$month'),6,2);
