【问题描述】：

我找不到如何通过 PowerShell 覆盖 Azure SQL Server 中现有数据库的方法。

Microsoft 或遇到此问题的人是否提供了任何选项，如何一次又一次地覆盖数据库...

这是我的代码如何复制它，但没有覆盖数据库的选项...任何帮助将不胜感激。

【问题讨论】：

如果您只想创建一个具有相同 DevDB 名称的新副本，那么您可能应该在复制之前只使用Remove-AzSqlDatabase。

谢谢Cpt.Whale。发布您的建议作为答案，以帮助其他社区成员。

要创建具有相同数据库名称的数据库的新副本，那么您需要使用相同的名称Remove-AzSqlDatabase，这样创建新的将很容易。

另外，您甚至可以重命名数据库，这将防止在重命名和恢复数据库时发生潜在的数据/数据库更改。
