T-SQL将数据插入加密列

基于大量研究，我下面的存储过程似乎可以工作。但是，无论是直接在SQLServer17中调用还是通过ADO连接调用，我都会遇到此错误

从数据类型varchar到varchar（255）加密的隐式转换 使用（加密类型='DETERMINISTIC'，加密算法名称= “AEAD_AES_256_CBC_HMAC_SHA_256”，列\u加密\u密钥\u名称= “AutoStripes\u Machine\u CEK”，列\u encryption\u key\u database\u name= “AutoStripes”）排序规则\u name='SQL\u Latin1\u General\u CP1\u CI\u AS'不可用 允许

我启用了

Column Encryption Setting=Enabled

，并为始终加密的签入查询选项启用参数化，并且我在使用的机器上有密钥

存储过程如下所示。我使用游标是因为不可能对临时表AFAIK进行加密，所以我想参数化VIN和插入记录后对这些字段执行update语句的位置条件

我错过了什么？还是根本不可能？

您的XML文档是否包含加密数据？如果没有，那么它就不会工作。SQL Server无法在本地加密/解密数据（这项技术的全部要点），因为它不包含加密数据@alex。谢谢我认为这就是答案。您的XML文档是否包含加密数据？如果没有，那么它就不会工作。SQL Server无法在本地加密/解密数据（这项技术的全部要点），因为它不包含加密数据@alex。谢谢我觉得这就是答案。
