CREATE TABLE logistics (
    id int auto_increment primary key,
    campaign VARCHAR(255),
    process_status VARCHAR(255),
    delivery_type VARCHAR(255),
    quantity INT

INSERT INTO logistics

)
VALUES 
("C001", "offer", "fedex", "500"),
("C001", "offer", "fedex", "200"),

campaign      process_status       delivery_type      quantity
C001          offer                fedex              700

C003          offer                fedex              730
C003          order                fedex              620        
C003          shipped              dhl                530
C005          offer                fedex              900
C005          shipped              ubs                475

在上表中，我有不同的campaigns，它们的process_status和delivery_type。
现在，我要提取所有campaigns，它们在不同的delivery_type之间切换其process_status。

因此，我正在寻找执行以下操作的查询：

SELECT
campaign,
process_status,
delivery_type,
quantity
FROM logistics
WHERE delivery_type differes in different process_status

我不知道WHERE条件如何才能达到预期的结果。
你有什么主意吗？

Answer 1

这将为您提供在不同过程状态下投放类型不同的所有广告系列：

SELECT (campaign),count(1) AS cnt
FROM logistics
GROUP BY campaign,
         delivery_type
HAVING cnt>1;

如果您想要唯一的广告系列值，则可以添加“ distinct”：

SELECT distinct(campaign),
       count(1) AS cnt
FROM logistics
GROUP BY campaign,
         delivery_type
HAVING cnt>1;

Answer 2

您可以尝试以下查询。

SELECT 
campaign, process_status, delivery_type, sum(quantity) as quantity
FROM logistics
WHERE campaign IN (
    SELECT
    campaign
    FROM logistics
    GROUP BY campaign
    HAVING max(delivery_type)!=min(delivery_type)
)
GROUP BY campaign, process_status, delivery_type

/* Match all values to campaigns that fullfill condition */
SELECT
l2.campaign,
l2.process_status,
l2.delivery_type,
SUM(l2.quantity)
from logistics l2
JOIN

  /* Get campaigns that fullfill condition */
   (SELECT
   t1.campaign,
   t1.process_status,
   t1.delivery_type,
   t1.count_process_status,
   t1.count_delivery_status
   FROM

     /* Count process_status and delivery_status */
     (SELECT
     l.campaign,
     l.process_status,
     l.delivery_type,
     COUNT(DISTINCT l.process_status) as count_process_status,
     COUNT(DISTINCT l.delivery_type) as count_delivery_status,
     SUM(l.quantity)
     FROM logistics l
     GROUP BY 1) t1

    WHERE count_delivery_status > 1) t2 ON l2.campaign = t2.campaign

GROUP BY 1,2,3;
