排除特定的記錄從SQL查詢

Question

我有一個SQL查詢，並希望取回這組數據集：

SELECT 
    Reference, DeliveryDate, SecondaryDate, PurchaseId, 
    ItemDescription, Status 
FROM 
    PLAYBOOK 
WHERE 
    (Supplier='PLAY') AND (Status = '0') 
ORDER BY 
    DeliveryDate DESC; 

但是我希望排除第一個查詢下方檢索到的數據集：

SELECT 
    Reference, DeliveryDate, SecondaryDate, PurchaseId, 
    ItemDescription, Status 
FROM 
    PLAYBOOK 
WHERE 
    (Supplier = 'PLAY') AND (Status = '0') AND (Tax = 'Yes') 
    AND (Problem = 'damaged'); 

Answer 1

利用這一點，如果你要照顧令的通過也。否則只用except

select * from 
(
SELECT Reference, DeliveryDate, SecondaryDate, PurchaseId, 
ItemDescription, Status FROM PLAYBOOK 
WHERE (Supplier='PLAY') AND (Status = '0') 

EXCEPT 

SELECT Reference, DeliveryDate, SecondaryDate, PurchaseId, 
ItemDescription, Status FROM PLAYBOOK 
WHERE (Supplier='PLAY') AND (Status = '0') AND (Tax = 'Yes') AND (Problem = 'damaged') 
) t1 
ORDER BY DeliveryDate DESC 

Answer 2

要回答您的具體問題（無需評論您所要求的是否是一個好主意）：

SELECT Reference, DeliveryDate, SecondaryDate, PurchaseId, 
ItemDescription, Status, FROM PLAYBOOK 
WHERE (Supplier='PLAY') AND (Status = '0') 
AND Reference NOT IN (
    SELECT Reference FROM PLAYBOOK 
    WHERE (Supplier='PLAY') 
    AND (Status = '0') 
    AND (Tax = 'Yes') 
    AND (Problem = 'damaged') 
) 
ORDER BY DeliveryDate DESC 

Answer 3

Just檢查附加條件

SELECT Reference, DeliveryDate, SecondaryDate, PurchaseId, 
ItemDescription, Status, FROM PLAYBOOK 
WHERE (Supplier='PLAY') AND (Status = '0') 
AND (Tax != 'Yes') AND (Problem != 'damaged') 
ORDER BY DeliveryDate DESC 

無需子查詢

Answer 4

你就不能使用一個查詢：

SELECT Reference, DeliveryDate, SecondaryDate, PurchaseId,ItemDescription, Status 
FROM PLAYBOOK 
WHERE (Supplier='PLAY') AND (Status = '0') AND ((Tax <> 'Yes') AND (Problem <> 'damaged')) 
ORDER BY DeliveryDate DESC;
