Question

我想删除以下查询返回的所有记录：

    SELECT *
    FROM [Customer] C
    INNER JOIN [BillingStatus] BS 
    ON BS.CustomerID = C.CustomerID 
    INNER JOIN [TCDetails] TC 
    ON TC.CustomerID = BS.CustomerID    
    INNER JOIN [BillingDetails] BD 
    ON BS.CustomerID = BD.CustomerID
    INNER JOIN [AgencyDetails] AD
    ON BD.CustomerID = AD.CustomerID
    INNER JOIN [CustomerDetails] CD
    ON CD.CustomerID = AD.CustomerID
    WHERE C.CYC = 27

Answer 1

您想要从所有表中删除，因此首先将客户ID声明为某个临时表可能会更简单：

SELECT CustomerID 
INTO #TempCustomer 
FROM Customer
WHERE CYC = 27

然后，您需要从每个表中删除：

DELETE FROM Customer WHERE CustomerID IN (SELECT CustomerID FROM #TempCustomer)
DELETE FROM BillingStatus WHERE CustomerID IN (SELECT CustomerID FROM #TempCustomer)
DELETE FROM TCDetails WHERE CustomerID IN (SELECT CustomerID FROM #TempCustomer)
DELETE FROM BillingDetails WHERE CustomerID IN (SELECT CustomerID FROM #TempCustomer)
DELETE FROM AgencyDetails WHERE CustomerID IN (SELECT CustomerID FROM #TempCustomer)
DELETE FROM CustomerDetails WHERE CustomerID IN (SELECT CustomerID FROM #TempCustomer)

最后，为了清理你，你应该删除你创建的临时表：

DROP TABLE #TempCustomer

Answer 2

从您的评论中删除Customer及其他表中的所有关系，首先将Cascade Delete的外键设置为Customer到其他表，然后Delete具有此查询的客户将删除所有其他表

DELETE FROM [Customer] WHERE CYC = 27

使用选择查询删除记录
