Question

我有3个数据扩展（数据表）

Subscription

CustomerInfo

Survey

所有三个表都将CustomerId作为字段。

以下是我的标准：

检查Bencriptids of Subscripton中的B13或B26

EmailInptin在CustomerInfo中为True

订阅中的CreateDt应该超过30天

他们在调查表中，具有以下条件：

QuestionId ='purchaseIntentQuestion'和AnswerId =＆＃39; 3＆＃39;       OR
      QuestionId =＆＃39; goldenQuestion＆＃39; AND（AnswerId =＆＃39; 1＆＃39; OR AnswerId =＆＃39; 2＆＃39;）

确保您没有Customerids的重复记录

我写了下面的查询，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也不是真的。请指教。

Answer 1

你说＆＃34;它没有按预期返回结果＆＃34;所以我真的不知道需要修复什么。我觉得CAST(GETDATE() -30 AS DATE)是个问题。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')))

需要加入3个具有复杂条件的表格
