有谁知道DDM是否必须先启用才能使用（以及如何），还是只有特定版本的SQL Server 2016才具有此功能运行：SQL Server 2016 - 动态数据屏蔽（DDM）
ALTER Table Employee
ALTER COLUMN NAME ADD MASKED WITH (FUNCTION='DEFAULT()')
导致以下错误：
Msg 534, Level 15, State 100, Line 4 'ADD MASKED' failed because it is not supported in the edition of this SQL Server instance 'DELL-001\SQLEXPRESS01'. See books online for more details on feature support in different SQL Server editions.
我已经安装了SQL的版本是：
Microsoft SQL Server 2016 (RTM-GDR) (KB3194716) - 13.0.1722.0 (X64)
Sep 26 2016 13:17:23 Copyright (c) Microsoft Corporation Express Edition (64-bit) on Windows 10 Home 6.3 (Build 14393:)
谢谢！
