对于所有的需求,当你不知道怎么处理的时候,你就先用最简单的方法,或者说的明白一点,用最原始的方法,先实现业务需求再说。
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:
1
2
3
4
5
6
7
8
9
10
11

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
1
2
3
4
5
6
|
//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
1
|
SELECT NOW(),CURDATE(),CURTIME()
|
例如
1
|
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:
1
2
3
4
5

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
1
2
3
4
5
6
7
8
9
|
//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
