如何在MySQL中按当前月份的当前年份计算总数

Question

I have bellow snippet table format.

Table name:- wp_lead_count_freevendor

id entryid start_date end_date   user_id count_set entry_date cancel_set_date
70 11392   2015-12-03 2015-12-03 3185            1 2015-12-03 2015-12-04
71 11393   2015-12-03 2015-12-03 3185            1 2015-12-03 2015-12-04
72 11394   2014-10-01 2014-10-01 3185            1 2014-10-01 2014-10-01

Here i want to calculate count total count_set column. of current month & year by start_date column WHERE user_id =3185.

suppose in start_date current year is 2015 & current month is 12:-

year   month   count total 
2015    12     2

For user id 3185 of this month of year count_set total =2

so any body will tell how do i fire the query to get count_set total for current year of current month for user_id =3185.

I have tried bellow query but its not working.

    $check_per_month=mysql_query("SELECT DATE_FORMAT(end_date, '%Y') as 'year',
    DATE_FORMAT(end_date, '%m') as 'month',
    COUNT(id) as 'total'
    FROM wp_lead_count_freevendor WHERE user_id=$wp_lead_count_user_id
    GROUP BY DATE_FORMAT(end_date, '%Y%m')") OR DIE(mysql_error());
    while($row = mysql_fetch_assoc($check_per_month))
    {

    echo $sql_chk_current_month_count=$row['total'];

    }

Answer 1

尝试使用where，year和month方法进行计数，如下所示：

SELECT .... WHERE YEAR(start_date)=2015 AND MONTH(start_date)=12

Answer 2

Try this query:

  SELECT YEAR(NOW()) as `year`,MONTH(NOW()) as `month', SUM(count_set) as `count_set`
  From  wp_lead_count_freevendor
     WHERE YEAR(start_date)=YEAR(NOW()) AND MONTH(start_date)=MONTH(NOW()) AND user_id=3185
        group by YEAR(NOW()),MONTH(NOW())
