MySQL 基於存儲過程 實現數據統計按日、周、月份統計模板

 

存儲過程developer_count 是根據傳入參數searchType 決定是使用那種查詢方式，本存儲過程中包含的其他的參數是{起始時間：startime,結束時間：endtime}

 

CREATE PROCEDURE developer_count
(
  searchType int,
    startTime varchar(64),
    endTime varchar(64)
)
BEGIN
    /*定義變量天數*/
  declare day_num int;

  if searchType = 1 then
  /*本周數據查詢*/
   select count(d.acct_id),d.acct_old_time from developer d where  1=1 and DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
    end if;
  if searchType = 2 then
    /*本月數據查詢*/
        select count(d.acct_id),d.acct_old_time from developer d where  1=1 and DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
  end if;
  if searchType = 3 then
    /*最近三個月數據查詢*/
        select count(d.acct_id), DATE_FORMAT(d.acct_old_time,'%x年-第%v周') as weeks from developer d where  1=1 and DATE_SUB(CURDATE(), INTERVAL 90 DAY) <= date(d.acct_old_time) GROUP BY weeks;
  end if;
  if searchType = 4 then
    /*按月份進行數據統計*/
        select datediff(startTime, endTime) into day_num;
        if day_num <=7 then
                select count(d.acct_id),d.acct_old_time from developer d where  1=1 and DATE_SUB(CURDATE(), INTERVAL day_num DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
        end if;
        if day_num >7  && day_num <= 30 then
                select count(d.acct_id),d.acct_old_time from developer d where  1=1 and DATE_SUB(CURDATE(), INTERVAL day_num DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
        end if;
        if day_num >30 && day_num <= 90 then
                select count(d.acct_id), DATE_FORMAT(d.acct_old_time,'%x年-第%v周') as weeks from developer d where  1=1 and DATE_SUB(CURDATE(), INTERVAL day_num DAY) <= date(d.acct_old_time) GROUP BY weeks;
        end if;
    end if;

end;

調用存儲過程方法

 

CALL DEVELOPER_COUNT(1,'2016-06-07','2016-06-16');調用存儲過程
