恢复SQL Server数据库 - 主密钥不打开 [英] Restoring SQL Server Database - Master Key Not Opening
问题描述
我必须制作远程SQL Server数据库的本地副本。我通过使用任务>从管理工作室备份。我然后在本地恢复备份，这似乎有一切 - 表，用户，对称密钥和证书。
I have to make a local copy of a remote SQL Server database. I did this by using Tasks > Backup from Management Studio. I then locally restored the backup, which seems to have everything -- tables, users, symmetric key, and certificate.
当我尝试执行一个需要我的选择打开对称密钥并通过证书解密，我得到这个错误：
When I try to perform a select that requires me to open the symmetric key and decrypt by the certificate, I get this error:
Please create a master key in the database or open the master key in the session before performing this operation.
为什么我被要求这个，为什么它不会像在远程服务器？
Why am I being asked for this, and why doesn't it open automatically like it does on the remote server?
我已经尝试更改主密钥，但没有原始密码，我不能做太多。
I've tried changing the master key, but without the original password, I can't do much.
推荐答案
问题是SMK已经改变（因为机器已经改变）。有一篇文章解释它这里。只需导出和导入SMK，请记住，您的复制系统中的任何加密数据将无法读取。
The problem is the SMK has changed (since the machine has changed). There's an article explaining it here. Just export and import the SMK -- bearing in mind that any encrypted data in your copied-to system will be unreadable.
MSDN文章：
- Backing up the SMK
- Restoring the SMK
