如何使用oneColumn上的Distinct和表上的Union來獲取所有列？

Question

我正在使用以下查詢基於以下3個條件從表中獲取唯一記錄數：

Select COUNT(*) FROM (   select distinct(SUBSCRIBER_EMAIL) from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '30000' and '31999'  
    Union   
select distinct(SUBSCRIBER_EMAIL) from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '39813' and '39901'  
    Union   
select distinct(SUBSCRIBER_EMAIL) from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '32000' and '34999'  
) Counts

現在我想要的是：我想獲取這些記錄的所有數據。

我努力了

 Select distinct(SUBSCRIBER_EMAIL), SUBSCRIBER_Id FROM  (select distinct(SUBSCRIBER_EMAIL),SUBSCRIBER_ID from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '30000' and '31999'
  Union    
 select distinct(SUBSCRIBER_EMAIL),SUBSCRIBER_ID from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '39813' and '39901'    
  Union 
 select distinct(SUBSCRIBER_EMAIL),SUBSCRIBER_ID from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '32000' and '34999'    
 ) x 

但是使用此方法我可以獲得所有記錄，這意味着在這種情況下，distinct無法正常工作。

請幫助我如何獲取與其他數據不同的電子郵件地址。

Answer 1

為什么不做這樣的區分：

SELECT distinct * from
(
  Select distinct(SUBSCRIBER_EMAIL), SUBSCRIBER_Id FROM  (select distinct(SUBSCRIBER_EMAIL),SUBSCRIBER_ID from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '30000' and '31999'
  Union    
 select distinct(SUBSCRIBER_EMAIL),SUBSCRIBER_ID from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '39813' and '39901'    
  Union 
 select distinct(SUBSCRIBER_EMAIL),SUBSCRIBER_ID from SUBSCRIBER where SUBSCRIBER_ACTIVE = 1  and SUBSCRIBER_ZIP between '32000' and '34999'    
)

Answer 2

第一個查詢可以是這樣的：

Select COUNT(*) FROM (   
select distinct(SUBSCRIBER_EMAIL) 
from SUBSCRIBER 
where SUBSCRIBER_ACTIVE = 1  
and (SUBSCRIBER_ZIP between '32000' and '34999'   
    OR SUBSCRIBER_ZIP between '30000' and '31999' 
    OR SUBSCRIBER_ZIP between '39813' and '39901')
) Counts

其次...如果您需要所有數據：

SELECT S.*
FROM SUBSCRIBER S
JOIN (   
select distinct(SUBSCRIBER_EMAIL) 
from SUBSCRIBER 
where SUBSCRIBER_ACTIVE = 1  
and (SUBSCRIBER_ZIP between '32000' and '34999'   
    OR SUBSCRIBER_ZIP between '30000' and '31999' 
    OR SUBSCRIBER_ZIP between '39813' and '39901')
) Counts
ON S.SUBSCRIBER_EMAIL = Counts.SUBSCRIBER_EMAIL
