从备份恢复数据库后无法连接到数据库

Question

我使用 SQL Server Management Studio 使用生产数据库制作的备份文件恢复了我的本地开发数据库。我在该还原时覆盖了我的本地数据库。

现在我无法使用 SQL Squirrel 连接到数据库。是什么原因造成的，如何解决？谢谢。

我在登录时收到错误消息"Unexpected Error occurred attempting to open an SQL connection."

您可能有一个孤立的用户。如果您的数据库用户未正确映射到同名登录名，服务器将无法将您连接到正确的数据库。您可以查看以下文章以获取故障排除帮助
