刪除返回的SQL結果

Question

如何刪除以下查詢返回的記錄？

Select HL.User from "Hobby List" HL 
INNER JOIN (Select SUBSTRING(Code,1,10) Code,Count(SUBSTRING(CODE,1,10)) 
AS Occurances from Patient where length(Patient.Code) > 10 
Group By SUBSTRING(Code,1,10) 
Having COUNT(SUBSTRING(Code,1,10)) > 1) P 
on SUBSTRING(HL.User,1,10) = P.Code 
Group By HL.User 

我試圖通過使用「刪除是否存在」的做法，要麼是錯還是我沒做正確，因爲它刪除表中的所有返回的記錄，而不是隻是那些刪除的記錄我的查詢。

感謝

Answer 1

試試這個：

DELETE FROM 'Hobby List' 
WHERE User IN 
(

Select HL.User from "Hobby List" HL 
INNER JOIN (Select SUBSTRING(Code,1,10) Code,Count(SUBSTRING(CODE,1,10)) 
AS Occurances from Patient where length(Patient.Code) > 10 
Group By SUBSTRING(Code,1,10) 
Having COUNT(SUBSTRING(Code,1,10)) > 1) P 
on SUBSTRING(HL.User,1,10) = P.Code 
Group By HL.User 

) 

Answer 2

DELETE FROM "Hobby List" HL WHERE HL.User IN (your query here) 

這應該這樣做的相當不錯，我這個在其他場景中使用了好幾次。
