Question

我有5个具有类似结构和类似名称的表，如Subscriptions_123，Subscriptions_456等。

我需要创建一个临时表，根据条件将所有这五个表数据组合在一起。

现在我首先创建一个临时表，然后将数据插入其中。是否有办法在另一个查询的from子句中创建临时表（使用此查询）。

Select
       MOB_NO
     , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
     , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE 
  from Subscriptions 
 where Subscription_Id in (select Distinct ServiceID 
                             from CommonLookup 
                            where ShortCode in (816602,816603,816604))
 UNION 
Select MOB_NO
     , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
     , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE

你可以使用select作为select的子选择，并以任何理由创建一个临时表：

select *
  into temp_table
  from (
        Select
               MOB_NO
             , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
             , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE 
          from Subscriptions 
         where Subscription_Id in (select Distinct ServiceID 
                                     from CommonLookup 
                                    where ShortCode in (816602,816603,816604))
         UNION 
        Select MOB_NO
             , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
             , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE 
          from Subscriptions_125
         where Subscription_Id in (select Distinct ServiceID 
                                     from CommonLookup 
                                    where ShortCode in (816602,816603,816604))
         UNION 
        Select MOB_NO
             , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
             , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE 
          from Subscriptions_467
         where Subscription_Id in (select Distinct ServiceID 
                                     from CommonLookup 
                                    where ShortCode in (816602,816603,816604))
         UNION 
        Select MOB_NO
             , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
             , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE 
          from Subscriptions_Campaign
         where Subscription_Id in (select Distinct ServiceID 
                                     from CommonLookup 
                                    where ShortCode in (816602,816603,816604))
         UNION 
        Select MOB_NO
             , CONVERT(DATE,Subscription_Start_Date) SUB_DATE
             , CONVERT(DATE,Unsubscribed_Date)       UNSUB_DATE

Answer 2

WITH AllData AS (
    SELECT MOB_NO
          ,Subscription_Start_Date
          ,Unsubscribed_Date
          ,Subscription_Id
    FROM Subscriptions
  UNION ALL
    SELECT MOB_NO
          ,Subscription_Start_Date
          ,Unsubscribed_Date
          ,Subscription_Id
    FROM Subscriptions_125
  UNION ALL
    ...
)
,Filtered AS (
    SELECT DISTINCT -- Only needed if your tables can contain duplicates
           MOB_NO
          ,CONVERT(DATE,Subscription_Start_Date) AS SUB_DATE
          ,CONVERT(DATE,Unsubscribed_Date) AS UNSUB_DATE 
    FROM AllTables
    WHERE SubscriptionId IN (SELECT ServiceID
                             FROM CommonLookup
                             WHERE ShortCode IN (816602,816603,816604))
)
SELECT * FROM Filtered

使用Union为类似的表创建临时表
