我试图删除多个数据/行表,但不允许我,因为错误始于 - > a,b,c,d,e< - 表示"无效列"并没有找到我的错误......在这里我的代码:
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
我试过很多选择:
DELETE FROM
DELETE * FROM
DELETE a.*,b.*,c.*,d.*,e.*
答案 0 :(得分:1)
DROP TABLE table1,table2,table3 ...
答案 1 :(得分:0)
DELETE t1, t2
FROM t1
INNER JOIN t2
INNER JOIN t3
WHERE t1.id = t2.id AND t2.id = t3.id;
答案 2 :(得分:0)
从DELETE子句中删除列(*):
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
这将删除每个表Providers
,UsersProviders
,Users
,ProviderSubscriptions
和Subscriptions
中的匹配行。
