MYSQL Double Counting Sum

Question

我想彙總印象表格中的觀點，但有些翻譯的答案是翻倍，因爲有些廣告系列的航班超過1次。

我將來自3個不同表格的數據組合在一起。 有什麼我可以做，所以只有一行從飛行表返回？

SELECT CAMPAIGN_CPM, CAMPAIGN.CAMPAIGN_ID, CAMPAIGN_NAME, MONTHNAME(IMP_DATE), SUM(VIEWS), CONCAT(MONTH(IMP_DATE),'-',YEAR(IMP_DATE)) AS MonthYear 
FROM IMPRESSION 
INNER JOIN CAMPAIGN 
ON IMPRESSION.CAMPAIGN_ID = CAMPAIGN.CAMPAIGN_ID 
INNER JOIN FLIGHT 
ON FLIGHT.CAMPAIGN_ID = CAMPAIGN.CAMPAIGN_ID 
WHERE MONTH(IMP_DATE) = MONTH(now() - interval 1 MONTH) AND CAMPAIGN_CPM > 0 
GROUP BY MONTHNAME(IMP_DATE), IMPRESSION.CAMPAIGN_ID, CAMPAIGN_CPM; 

如果有其他信息需要請告訴我。

在此先感謝。

試試這個：

我已經加入飛行表明，一個航班號顯示，我從觀點改變了位置。

SQL代碼：

SELECT * FROM (
SELECT FLIGHT.FLIGHT_ID, SUM(VIEWS), CAMPAIGN_CPM, CAMPAIGN.CAMPAIGN_ID, CAMPAIGN_NAME, MONTHNAME(IMP_DATE), CONCAT(MONTH(IMP_DATE),'-',YEAR(IMP_DATE)) AS MonthYear 
FROM IMPRESSION 
INNER JOIN CAMPAIGN 
ON IMPRESSION.CAMPAIGN_ID = CAMPAIGN.CAMPAIGN_ID 
INNER JOIN FLIGHT 
ON FLIGHT.CAMPAIGN_ID = CAMPAIGN.CAMPAIGN_ID 
WHERE MONTH(IMP_DATE) = MONTH(now() - interval 1 MONTH) AND CAMPAIGN_CPM > 0 
GROUP BY MONTHNAME(IMP_DATE), IMPRESSION.CAMPAIGN_ID, CAMPAIGN_CPM 
) a GROUP BY a.CAMPAIGN_ID; 

，因爲我曾與樣本數據來填充這些表我已經取得了一些小的改動。此外，主鍵和級聯存在一些問題。但是，每個人都應該在你的版本中工作。

表結構：

CREATE TABLE `FLIGHT` (
    `FLIGHT_ID` int(11) NOT NULL PRIMARY KEY, 
    `FLIGHT_NAME` varchar(255) DEFAULT NULL, 
    `FLIGHT_START_DATE` date DEFAULT NULL, 
    `FLIGHT_END_DATE` date DEFAULT NULL, 
    `CAMPAIGN_FREQUENCY` int(11) DEFAULT NULL, 
    `CAMPAIGN_FREQUENCY_PERIOD` varchar(255) DEFAULT NULL, 
    `CAMPAIGN_CPM` double DEFAULT NULL, 
    `CAMPAIGN_STATUS` varchar(255) DEFAULT NULL, 
    `CUSTOM_CAMPAIGN_TYPE` varchar(255) DEFAULT NULL, 
    `CAMPAIGN_ID` int(11) NOT NULL 
) ENGINE=InnoDB DEFAULT CHARSET=utf8; 

CREATE TABLE `IMPRESSION` (
    `IMP_DATE` date NOT NULL, 
    `CAMPAIGN_ID` int(11) NOT NULL, 
    `BANNER_ID` int(11) DEFAULT NULL, 
    `CUSTOMER_ID` int(11) DEFAULT NULL, 
    `ADVERTISER_ID` int(11) DEFAULT NULL, 
    `PLACEMENT_ID` int(11) DEFAULT NULL, 
    `IMPRESSIONS_WITH_DEFAULTS` int(11) DEFAULT NULL, 
    `IMPRESSIONS_WITHOUT_DEFAULTS` int(11) DEFAULT NULL, 
    `VIEWS` int(11) DEFAULT NULL, 
    `DEFAULTS` int(11) DEFAULT NULL, 
    `CLICKS` int(11) DEFAULT NULL, 
    `IMPRESSION_ID` int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY 
) ENGINE=InnoDB AUTO_INCREMENT=35673 DEFAULT CHARSET=utf8; 

CREATE TABLE `CAMPAIGN` (

    `CAMPAIGN_START_DATE` date DEFAULT NULL, 
    `CAMPAIGN_END_DATE` date DEFAULT NULL 
) ENGINE=InnoDB DEFAULT CHARSET=utf8; 

樣本數據：

INSERT INTO FLIGHT (FLIGHT_ID, CAMPAIGN_ID,CAMPAIGN_CPM)
