OPEN MASTER KEY (Transact-SQL)

SQL Server 2005

開啟目前資料庫的資料庫主要金鑰。

主題連結圖示 Transact-SQL 語法慣例

複製 

OPEN MASTER KEY DECRYPTION BY PASSWORD = 'password'
'password'

用來加密資料庫主要金鑰的密碼。

如果利用服務主要金鑰來加密資料庫主要金鑰，當解密或加密需要它時，會自動開啟它。在這個情況下，不需要使用 OPEN MASTER KEY 陳述式。

當資料庫第一次連接到新的 SQL Server 執行個體時，資料庫主要金鑰副本 (服務主要金鑰所加密) 尚未儲存在伺服器中。您必須利用 OPEN MASTER KEY 陳述式來解密資料庫主要金鑰。資料庫主要金鑰解密之後，您便可以選擇利用 ALTER MASTER KEY 陳述式來提供服務主要金鑰所加密的資料庫主要金鑰副本給伺服器，以在未來啟用自動解密。＜ALTER MASTER KEY (Transact-SQL)＞中有這個選項的內容討論。

您可以設定 DROP ENCRYPTION BY SERVICE MASTER KEY 選項來使用 ALTER MASTER KEY 陳述式，以從自動金鑰管理中排除特定資料庫的資料庫主要金鑰。之後，您必須利用密碼來明確開啟資料庫主要金鑰。

如果回復明確開啟資料庫主要金鑰的交易，金鑰會維持開啟狀態。

需要資料庫的 CONTROL 權限。

下列範例會開啟 AdventureWorks 資料庫已利用密碼來加密的資料庫主要金鑰。

複製 
USE AdventureWorks;
OPEN MASTER KEY DECRYPTION BY PASSWORD = '43987hkhj4325tsku7';
