[<CommonParameters>] 说明
Mount-SPContentDatabase cmdlet 将现有内容数据库附加到服务器场。 如果安装的数据库需要升级，此 cmdlet 将导致升级该数据库。 注意：请注意，如果指定了不存在的内容数据库，则此 cmdlet 将创建该数据库。
此 cmdlet 的默认行为将导致数据库架构升级，并对指定内容数据库中的所有网站集启动升级后的内部版本（如果需要）。 若要阻止启动升级后的网站集内部版本，可使用 NoB2BSiteUpgrade 参数。 此 cmdlet 不会触发任何网站集的版本间升级。
有关适用于 SharePoint 产品的 Windows PowerShell 的权限和最新信息，请参阅 SharePoint Server cmdlet。
示例
-----------------示例 1---------------------
Mount-SPContentDatabase "MyDatabase" -DatabaseServer "MyServer" -WebApplication https://sitename此示例将一个现有数据库装载到 sitename Web 应用程序中。 如果需要升级，它将触发数据库架构升级，然后只对现有网站集执行内部版本间升级操作（如果需要）。 此操作不会改变此数据库中现有网站集的 CompatibilityLevel。
-----------------示例 2---------------------
Mount-SPContentDatabase "MyDatabase" -DatabaseServer "MyServer" -WebApplication https://sitename -NoB2BSiteUpgrade此示例将一个现有数据库装载到 sitename Web 应用程序中，但它阻止发生任何网站升级。 如果需要升级，它将只触发数据库架构升级，而不对任何网站集执行内部版本间升级操作。 此操作不会改变此数据库中现有网站集的 CompatibilityLevel。
参数
-AssignmentCollection
管理对象以便正确进行处理。 使用 SPWeb 或 SPSite 等对象可能会耗用大量内存，而且在 Windows PowerShell 脚本中使用这些对象需要正确管理内存。 通过使用 SPAssignment 对象，可以将对象分配给变量，然后在不需要这些对象时对它们进行处理，以释放内存。 在使用 SPWeb、SPSite 或 SPSiteAdministration 对象时，如果不使用分配集合或 Global 参数，则会自动处理这些对象。
在使用 Global 参数时，所有对象均包含在全局存储中。 如果未立即使用对象，或未通过使用 Stop-SPAssignment 命令来处理对象，则可能会发生内存不足的情况。
