使用cross db ownership chaining选项可以为 Microsoft SQL Server 实例配置跨数据库所有权链接。 此服务器选项使您能够在数据库级别控制跨数据库所有权链接,或者允许在所有数据库中启用跨数据库所有权链接: 如果实例的cross db ownership chaining关闭(设置为 0),将禁用所有数据库的跨数据库所有权链接。
附加和分离操作都会禁用数据库的跨数据库所有权链接。 有关如何启用链接的详细信息,请参阅 cross db ownership chaining 服务器配置选项。有关详细信息,请参阅《将镜像数据库设置为使用 Trustworthy 属性 (Transact-SQL)》数据库所有权在其他计算机上还原数据库时,启动还原操作的 SQL Server 登录用户或 Windows 用户...
