MySQL - 일별통계

SELECT DATE(`reg_date`) AS `date`, 
       sum(`value`)
  FROM test_st
 GROUP BY `date`;

MySQL - 주간통계

SELECT DATE_FORMAT(DATE_SUB(`reg_date`, INTERVAL (DAYOFWEEK(`reg_date`)-1) DAY), '%Y/%m/%d') as start,
       DATE_FORMAT(DATE_SUB(`reg_date`, INTERVAL (DAYOFWEEK(`reg_date`)-7) DAY), '%Y/%m/%d') as end,
       DATE_FORMAT(`reg_date`, '%Y%U') AS `date`, 
       sum(`value`)
  FROM test_st
 GROUP BY date;

MySQL - 월간통계

SELECT MONTH(`reg_date`) AS `date`, 
       sum(`value`)
  FROM test_st
 GROUP BY `date`;

기간별 통계

SELECT DATE(`reg_date`) AS `date`,
       sum(`value`)
  FROM test_st
 WHERE DATE(`reg_date`) >= STR_TO_DATE('2017-04-01', '%Y-%m-%d')
   AND DATE(`reg_date`) <= STR_TO_DATE('2017-04-10', '%Y-%m-%d')
 GROUP BY `date`;
