Get from database but only last 30 days

Question

I\'m using this php to fetch data from my mysql database:

$wpdb->get_var(\"select count(*) from \" . $wpdb->prefix . \"newsletter where status=\'C\'\")         


        

Answer 1

    $wpdb->get_var("select count(*) from " . $wpdb->prefix . "newsletter where status='C'
 AND DATEDIFF(CURDATE(), created) <= 30"); ?>

Used:

DATEDIFF() - returns expr1 – expr2 expressed as a value in days from one date to the other. expr1 and expr2 are date or date-and-time expressions. Only the date parts of the values are used in the calculation.

And:

CURDATE() - Current date
