MySQL 基于存储过程 实现数据统计按日、周、月份统计模板

 

存储过程developer_count 是根据传入参数searchType 决定是使用那种查询方式，本存储过程中包含的其他的参数是{起始时间：startime,结束时间：endtime}

 

CREATE PROCEDURE developer_count
(
  searchType int,
    startTime varchar(64),
    endTime varchar(64)
)
BEGIN
    /*定义变量天数*/
  declare day_num int;

  if searchType = 1 then
  /*本周数据查询*/
   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
    /*本月数据查询*/
        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
    /*最近三个月数据查询*/
        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
    /*按月份进行数据统计*/
        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;

调用存储过程方法

 

CALL DEVELOPER_COUNT(1,'2016-06-07','2016-06-16');调用存储过程
