來(lái)源：本站原創(chuàng)|時(shí)間：2020-01-10|欄目：MsSql|點(diǎn)擊：次

　對(duì)于所有的需求，當(dāng)你不知道怎么處理的時(shí)候，你就先用最簡(jiǎn)單的方法，或者說(shuō)的明白一點(diǎn)，用最原始的方法，先實(shí)現(xiàn)業(yè)務(wù)需求再說(shuō)?！　?/p>

一、對(duì)提現(xiàn)隊(duì)列數(shù)據(jù)表“ims_checkout_task”進(jìn)行匯總統(tǒng)計(jì)，按月匯總統(tǒng)計(jì)每個(gè)月的提現(xiàn)總額，提現(xiàn)總次數(shù)。

　　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、數(shù)據(jù)庫(kù)返回如下：

　　3、關(guān)鍵詞：case when

//流程控制語(yǔ)句case語(yǔ)法，例如，如果sex字段值為1，則輸出男；如果sex值為2，則輸出女；否則輸出其他
CASE sex
WHEN '1' THEN '男'
WHEN '2' THEN '女'
ELSE '其他' END
//所以上面的SQL為，如果條件成立，則輸出提現(xiàn)金額money字段，否則輸出0.

　　時(shí)間處理

//對(duì)時(shí)間戳格式化成 2018-10
FROM_UNIXTIME(addTime,'%Y-%m')
//SQL獲取當(dāng)前時(shí)間格式 2019-08 ,根據(jù)expr值不同，依次獲取前一個(gè)月1，前兩個(gè)月2 ···
DATE_FORMAT(DATE_SUB(CURDATE(), INTERVAL 0 MONTH),'%Y-%m')
// 函數(shù)用于以不同的格式顯示日期/時(shí)間數(shù)據(jù)。
DATE_FORMAT(date,format)
//函數(shù)從日期減去指定的時(shí)間間隔。
DATE_SUB(date,INTERVAL expr type)
//函數(shù)返回當(dāng)前的日期。
CURDATE()

　　例如

SELECT NOW(),CURDATE(),CURTIME()

　　例如

SELECT DAYOFWEEK(NOW()),WEEKDAY(now()),DATE_FORMAT(NOW(),"%w"),NOW()

二、對(duì)積分訂單數(shù)據(jù)表按周匯總統(tǒng)計(jì)訂單量，比如今天是周二，返回周一到周二的每天單量匯總數(shù)據(jù)，依次類(lèi)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、數(shù)據(jù)庫(kù)返回如下：

　　3、關(guān)鍵詞

//格式化時(shí)間戳，返回星期數(shù)，注意周日返回值為0
DATE_FORMAT(FROM_UNIXTIME(pay_time,'%Y-%m-%d'),'%w')
//返回當(dāng)前時(shí)間為一年中第幾周
WEEK(DATE_ADD(CURDATE(),interval 6 day),2)
//獲取指定日期是一年中的第幾周
WEEK(date,mode)
//函數(shù)向日期添加指定的時(shí)間間隔。
DATE_ADD(date,INTERVAL expr type)
//所以上面的查詢條件為星期和第幾周同時(shí)滿足

影子是一個(gè)會(huì)撒謊的精靈，它在虛空中流浪和等待被發(fā)現(xiàn)之間;在存在與不存在之間....
