需要加入 3 个条件复杂的表

Question

我有 3 个数据扩展（数据表）

Subscription

CustomerInfo

Survey

所有三个表都有 CustomerId 作为字段。

以下是我的标准：

1. 在下标的 Benfitids 中检查 B13 或 B26
2. CustomerInfo 中的 EmailOptin 为 True
3. 订阅中的 CreateDt 应超过 30 天并且
4. 他们在调查表中具有以下条件：

QuestionId= 'purchaseIntentQuestion' 和 AnswerId = '3' 或
QuestionId='goldenQuestion' AND (AnswerId = '1' OR AnswerId = '2')

确保您没有重复的 Customerid 记录

我编写了以下查询，但它没有按预期返回结果。请指教

SELECT distinct sub.CustomerId, Cus.EmailOptin, srv.QuestionID,srv.AnswerId
FROM [Subscription] sub
JOIN [Survey Questions] srv ON sub.CustomerId = srv.CustomerId
JOIN [CustomerInfo] cus ON sub.CustomerId = cus.CustomerId
WHERE 1 = 1
AND CAST(sub.CreateDt AS DATE) < CAST(GETDATE() -30 AS DATE)
AND Cus.EmailOptin  = 'True'
AND 
(
sub.BenefitIds LIKE '%B13%'
OR
sub.BenefitIds LIKE '%B26%'
)
AND 
(
(srv.QuestionId = 'purchaseIntentQuestion' AND srv.AnswerId = '3')
OR 
(srv.QuestionId = 'goldenQuestion' AND (srv.AnswerId = '1' OR srv.AnswerId = '2' ))
)

对于上述查询，即使 EmailOptin 也不是 True。 请指教。

Answer 1

您说“它没有按预期返回结果”所以我真的不知道需要修复什么。我觉得CAST(GETDATE() -30 AS DATE) 是问题所在。为了便于阅读，我还将OR 替换为IN()。试试这个：

SELECT distinct sub.CustomerId,
                Cus.EmailOptin,
                srv.QuestionID,
                srv.AnswerId
  FROM [ Subscription ] sub
  JOIN [ Survey Questions ] srv
    ON sub.CustomerId = srv.CustomerId
  JOIN [ CustomerInfo ] cus
    ON sub.CustomerId = cus.CustomerId
 WHERE 1 = 1
   AND CAST(sub.CreateDt AS DATE) < DATE_ADD(NOW(), INTERVAL 30 DAY) 
   AND Cus.EmailOptin = 'True'
   AND (sub.BenefitIds = '%B13%' OR sub.BenefitIds LIKE '%B26%')
   AND ((srv.QuestionId = 'purchaseIntentQuestion' AND srv.AnswerId = '3') OR
       (srv.QuestionId = 'goldenQuestion' AND
       srv.AnswerId IN('1','2')))
