【MYSQL】基于存储过程实现数据统计按日、周、月份统计模板

作者: / 发布于2018/6/13/ 968

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;
