Question

由于我们很快将在英国实施法规变更，我正在制作的数据库需要更新以加密任何个人身份信息。

我的一些表已成功更改，但是在某些有触发器的表上，我收到以下错误。

错误SQL72014：.Net SqlClient数据提供程序：消息206，级别16，状态2，过程tr_Employee_Update，第27行操作数类型冲突：varchar与使用（encryption_type ='DETERMINISTIC'，encryption_algorithm_name ='加密的varchar（max）不兼容AEAD_AES_256_CBC_HMAC_SHA_256'，column_encryption_key_name ='CEK_Auto1'，column_encryption_key_database_name ='xxxx'）collation_name ='Latin1_General_BIN2'

我在这里看过这个问题，但这并没有解决我的问题Operand type clash: varchar is incompatible with varchar(50) trying to insert in encrypted database

同样这个问题也在哪里不能完全解决我的问题。 SQL Server Always Encrypted Operand type clash: varchar is incompatible with varchar(60) when running EXEC sproc

我在很多表上都有这个问题，所以对任何和所有的帮助都会感激不尽。

请在此处查看SQL小提琴

http://sqlfiddle.com/#!18/4ac5c/3

我不得不拆分表并触发创建，因为SQL长度大于8000个字符，但这是我能给出的最完整的例子。

我使用加密类型加密列：确定性和加密密钥名称：CEK_Auto1。

此表中并非所有列都需要加密，而且我正在更改其他一些具有默认值的字段，并且需要进行加密。

感谢收到有关报道问题的任何和所有帮助。

在对此进行了大量研究之后，目前很不幸的是，无论数据类型如何，都不支持更新加密列的触发器。因此，任何偶然发现这个问题且遇到同样问题的人都需要通过存储过程完成更新，但需要通过应用程序代码调用它们。

虽然上述问题中的两个相关问题并未直接解决我的问题或帮助我，但您可能需要按照问题中的答案来帮助您将参数化值传递给存储过程并产生问题。
