首先让我说我尝试在其上设置 TDE（透明数据加密）的 SQL Server 2012 实例是企业版。
但是，在遵循MSDN 教程教程时，我会看到以下行：
create database encryption key with algorithm = AES_256 encryption by server certificate TDECertificate
我得到错误：
Msg 33117, Level 16, State 1, Line 6
Transparent Data Encryption is not available in the edition of this SQL Server instance. See books online for more details on feature support in different SQL Server editions.
谁能告诉我为什么我会收到这个错误？
