Question

我试图从印象表中总结一下观点，但有些人的答案加倍，因为某些广告系列有超过1次广告投放。

我正在组合来自3个不同表格的数据。 我能做些什么，所以只返回航班表中的一行吗？

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;

如果需要任何其他信息，请告诉我。

表

试试这个：

我已添加FLIGHT以显示已显示一个航班号，并且我从视图中更改了位置。

SQL代码：

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;

我做了一些小改动，因为我不得不用表格填充表格。此外，主键和级联存在一些问题。但是，Every应该适用于您的版本。

表结构：

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_ID` int(11) NOT NULL PRIMARY KEY,
  `CAMPAIGN_NAME` varchar(255) DEFAULT NULL,
  `CAMPAIGN_START_DATE` date DEFAULT NULL,
  `CAMPAIGN_END_DATE` date DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

示例数据：

INSERT INTO FLIGHT (FLIGHT_ID, CAMPAIGN_ID,CAMPAIGN_CPM)
VALUES (255060,1,250),
(255080,1,250),
(255070,1,250),
(255020,1,40),
(255025,2,300),
(255040,3,250),
(255045,3,20),
(255046,3,100),
(255071,4,210),
(255055,5,280);

INSERT INTO IMPRESSION (IMP_DATE,CAMPAIGN_ID, VIEWS)
VALUES 
((NOW() - INTERVAL 10 DAY),1,250),
((NOW() - INTERVAL 1 MONTH),2,4050),
((NOW() - INTERVAL 1 MONTH),3,10),
((NOW() - INTERVAL 3 DAY),3,40),
((NOW() - INTERVAL 1 MONTH),3,10),
((NOW() - INTERVAL 3 DAY),4,40),
((NOW() - INTERVAL 1 MONTH),5,1350);

INSERT INTO CAMPAIGN (CAMPAIGN_ID, CAMPAIGN_NAME)
VALUES 
(1,'jkajoiuwejoijdkjjklja'),
(2,'ajiuiouwoihajdhjhhjh'),
(3, 'aauuehxbhchuhnb'),
(4,'aduuiuhzjcnckjnxkj'),
(5,'zzzdfhjfhajkhwkjeajqw');
