Question

lets say I have a “Datetime” column in DB. It has a data like “2010-10-01 09:12:00”.
Beside that, i want to make a searching page which have:

<select id="month" name="month">
       <option value="01">01</option>
       <option value="02">02</option>
       ...
</select>
<input type="text" id="year" name="year">

How do i do to get data if i choose month=10 and year=2010?

Answer 1

SELECT * 
FROM   your_table 
WHERE  MONTH(your_date) = '10' AND YEAR(your_date) = '2010';

Be aware that the above won’t be able to use an index on your date column, if one exists. To use an index, you’d have to use something like this:

SELECT * 
FROM   your_table 
WHERE  your_date >= STR_TO_DATE(CONCAT('2010', '-', '10', '-01'), '%Y-%m-%d') AND
       your_date < STR_TO_DATE(CONCAT('2010', '-', '10', '-01'), '%Y-%m-%d') + INTERVAL 1 MONTH;
