I have a date field in my MySQL database and it stores the date of type y-m-d which is already used in other queries, but now I need to capture only the month to make a sum.

The code I have is this

date_default_timezone_set('America/Sao_Paulo');
        $datamensal = date('m-d');
        $stw = mysql_query("SELECT SUM(valortotal) as total_mensal FROM pedidos WHERE data = '$datamensal'");

But it did not work .... Does anyone know the correct way to perform this action?

php mysql

Use the month () MySQL to compare only the month with the desired value. There are other functions to extract a piece of date as year() , day() etc.

select month(now()) #retorna 11

or

$datamensal = date('m');
$stw = mysql_query("SELECT SUM(valortotal) as total_mensal FROM pedidos 
                    WHERE month(data) = '$datamensal' AND year(data) = year(now())")
       or die(mysql_error());

while($row = mysql_fetch_assoc($stw)){
   echo $row['total_mensal'] .'<br>';
}
