帶左連接的SQL Server UPDATE？

Question

我想更新一個表格，這個表格有多對一的關係。該表包含可以很多的會員資格，並且它們與一個人聯繫在一起。

會員可以是客戶或從業者，所以他們有一個客戶ID或從業者ID。

請問你是否需要更多信息，下面是我的嘗試，我嘗試了UPDATE下的所有左連接，並且沒有從，但是我已經發布了這個例子，因爲我認爲它最好顯示我是什麼試圖去做。

UPDATE 
    MembershipUser AS MU 
SET 
    MU.AccountLastUsed = 0 
FROM 
    Person AS P 
    LEFT JOIN Practitioner AS Pr ON Pr.PersonId = P.PersonId 
    LEFT JOIN Client AS C ON C.PersonId = P.PersonId 
    LEFT JOIN MembershipUser AS MU ON MU.PractitonerId = Pr.PractitionerId OR ON MU.ClientId = C.ClientId 
WHERE 
    P.PersonId = @PersonId 

有人可以幫我在這裏，你可以做一個更新與左加入？

Answer 1

嘗試以下查詢：

UPDATE MembershipUser 
SET MU.AccountLastUsed = 0 
FROM Person AS P 
    LEFT JOIN Practitioner AS Pr ON Pr.PersonId = P.PersonId 
    LEFT JOIN Client AS C ON C.PersonId = P.PersonId 
Where 
    P.PersonId = @PersonId 
    and (MembershipUser.PractitonerId = Pr.PractitionerId OR MembershipUser.ClientId = C.ClientId) 

OR：

UPDATE z  
SET AccountLastUsed = 0 
FROM (
    SELECT Mu.Id, Mu.AccountLastUsed 
    FROM 
     Person AS P 
     LEFT JOIN Practitioner AS Pr ON Pr.PersonId = P.PersonId 
     LEFT JOIN Client AS C ON C.PersonId = P.PersonId 
     LEFT JOIN MembershipUser AS MU ON MU.PractitonerId = Pr.PractitionerId OR ON MU.ClientId = C.ClientId 
    WHERE 
     P.PersonId = @PersonId 
    )z
