SQL对数据进行按月统计或对数据进行按星期统计的实例代码
时间:2022-06-29 09:05:51 编辑:袖梨 来源:一聚教程网
本篇文章小编给大家分享一下SQL对数据进行按月统计或对数据进行按星期统计的实例代码,小编觉得挺不错的,现在分享给大家供大家参考,有需要的小伙伴们可以来看看。
一、对提现队列数据表“ims_checkout_task”进行汇总统计,按月汇总统计每个月的提现总额,提现总次数。
1、SQL操作如下:
SELECT id ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 11 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '0' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 10 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '1' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 9 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '2' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 8 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '3' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 7 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '4' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 6 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '5' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 5 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '6' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 4 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '7' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 3 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '8' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 2 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '9' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '10' ,SUM(case when FROM_UNIXTIME(addTime,'%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 0 MONTH),'%Y-%m') AND `status` = 1 then money else 0 end) as '11' FROM ims_checkout_task
2、数据库返回如下:
3、关键词:case when
//流程控制语句case语法,例如,如果sex字段值为1,则输出男;如果sex值为2,则输出女;否则输出其他 CASE sex WHEN '1' THEN '男' WHEN '2' THEN '女' ELSE '其他' END //所以上面的SQL为,如果条件成立,则输出提现金额money字段,否则输出0.
时间处理
//对时间戳格式化成 2018-10 FROM_UNIXTIME(addTime,'%Y-%m') //SQL获取当前时间格式 2019-08 ,根据expr值不同,依次获取前一个月1,前两个月2 ··· DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 0 MONTH),'%Y-%m') // 函数用于以不同的格式显示日期/时间数据。 DATE_FORMAT(date,format) //函数从日期减去指定的时间间隔。 DATE_SUB(date,INTERVAL expr type) //函数返回当前的日期。 CURDATE()
例如
SELECT NOW(),CURDATE(),CURTIME()
例如
SELECT DAYOFWEEK(NOW()),WEEKDAY(now()),DATE_FORMAT(NOW(),"%w"),NOW()
二、对积分订单数据表按周汇总统计订单量,比如今天是周二,返回周一到周二的每天单量汇总数据,依次类推
1、SQL操作如下:
SELECT id ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 1 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '0' ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 2 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '1' ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 3 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '2' ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 4 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '3' ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 5 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '4' ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 6 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '5' ,SUM(case when DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') = 0 AND WEEK(date_add(curdate(),interval 6 day),2) = WEEK(date_add(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),interval 6 day),2) AND `pay_status` = 1 then 1 else 0 end) as '6' FROM ims_integral_order
2、数据库返回如下:
3、关键词
//格式化时间戳,返回星期数,注意周日返回值为0 DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w') //返回当前时间为一年中第几周 WEEK(DATE_ADD(CURDATE(),interval 6 day),2) //获取指定日期是一年中的第几周 WEEK(date,mode) //函数向日期添加指定的时间间隔。 DATE_ADD(date,INTERVAL expr type) //所以上面的查询条件为星期和第几周同时满足
影子是一个会撒谎的精灵,它在虚空中流浪和等待被发现之间;在存在与不存在之间....
