Question

我在插入新行后尝试更新ssn列。指定我需要将null设置为ssn列并将该加密值设置为另一列。我的触发器有什么错误或有什么问题吗？

ALTER TRIGGER [dbo].[MemberInsert]
ON [dbo].[Member]
AFTER INSERT
AS 
BEGIN   
SET NOCOUNT ON;

OPEN SYMMETRIC KEY SSN_Key
    DECRYPTION BY CERTIFICATE MyCer;

UPDATE Member
SET  [EncryptedSSN] = EncryptByKey(Key_GUID('SSN_Key'), inserted.SSN)
FROM inserted
INNER JOIN dbo.Member On inserted.MemberId = Member.MemberId

UPDATE Member
SET [SSN] = null 
FROM inserted
INNER JOIN dbo.Member On inserted.MemberId = Member.MemberId
END

现在添加行没有任何结果。此外，我必须添加使用SqlBulkCopy插入新行。触发器以这种方式捕获事件是否有问题？

默认情况下，SqlBulkCopy不会检查触发器，您必须指定选项：SqlBulkCopyOptions

var options = SqlBulkCopyOptions.FireTriggers | SqlBulkCopyOptions.CheckConstraints;
using (var bulkCopy = new SqlBulkCopy(connection, options, transaction))
{
    // ...Code...
}

在SqlBulkCopy写入服务器新行后，DB触发器将不会执行
