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;
