tSQL NOT IN查詢

Question

我想獲取[interact]表的ID，但這些ID不能等於[EmailOUT]表。我無法寫出查詢。

Select ID from EmailOut   
where ID NOT IN   
    (select ID from 
    [172.28.101.120].[GenesysIS].dbo.interactions 
    where media_type = 'email' 
    and type = 'Outbound') 

與此類似的東西。我想在交互表中輸出電子郵件，但這些電子郵件可能存在於EmailOut表中。我想刪除它們。出站電子郵件數約爲300，但這個查詢結果應該小於300

Answer 1

看來你應該反向查詢，如果你想獲得[互動]表中的ID：

select ID from 
[172.28.101.120].[GenesysIS].dbo.interactions 
where media_type = 'email' 
and type = 'Outbound' 
AND ID NOT IN (SELECT ID FROM EmailOut) 

Answer 2

什麼

select ID from [172.28.101.120].[GenesysIS].dbo.interactions 
where media_type = 'email' 
and type = 'Outbound' 
minus 
select ID from EmailOut 

Answer 3

嘗試這一個 -

SELECT t2.* 
FROM [172.28.101.120].[GenesysIS].dbo.interactions t2 
WHERE t2.media_type = 'email' 
    AND t2.[type] = 'Outbound' 
    AND NOT EXISTS (
      SELECT 1 
      FROM dbo.EmailOut t 
      WHERE t.id = t2.id 
     )
