有誰知道DDM是否必須先啓用才能使用（以及如何），還是隻有特定版本的SQL Server 2016才具有此功能運行：SQL Server 2016 - 動態數據屏蔽（DDM）
ALTER Table Employee
ALTER COLUMN NAME ADD MASKED WITH (FUNCTION='DEFAULT()')
導致以下錯誤：
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.
我已經安裝了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:)
謝謝！
