刪除多個表的SQL

Question

我試圖刪除多個數據/行表，但不允許我這樣做，因為錯誤始於-> a，b，c，d，e <-表示“無效列”，但找不到我的錯誤...這是我的代碼：

DELETE a.*,b.*,c.*,d.*,e.* FROM [CatMngSys].[Providers] a
INNER JOIN [Security].[UsersProviders] b
ON a.Id = b.ProviderId
INNER JOIN [Security].[Users] c
ON b.UserId = c.Id
INNER JOIN [CatMngSys].[ProviderSubscriptions] d
ON d.ProviderId = a.Id
INNER JOIN [CatMngSys].[Subscriptions] e
ON e.Id = d.SubscriptionId
WHERE a.id = @Id

我已經嘗試了很多選擇：

DELETE FROM 
DELETE * FROM
DELETE a.*,b.*,c.*,d.*,e.* 

Answer 1

 DROP TABLE table1,table2,table3 ...

Answer 2

DELETE t1, t2 
FROM t1 
INNER JOIN t2 
INNER JOIN t3
WHERE t1.id = t2.id AND t2.id = t3.id;

Answer 3

從DELETE子句中刪除列（*）：

DELETE a, b, c, d, e
FROM [CatMngSys].[Providers] a
INNER JOIN [Security].[UsersProviders] b ON a.Id = b.ProviderId
INNER JOIN [Security].[Users] c ON b.UserId = c.Id
INNER JOIN [CatMngSys].[ProviderSubscriptions] d ON d.ProviderId = a.Id
INNER JOIN [CatMngSys].[Subscriptions] e ON e.Id = d.SubscriptionId
WHERE a.id = @Id

這將刪除表Providers ， UsersProviders ， Users ， ProviderSubscriptions和Subscriptions匹配行。
