从备份恢复数据库后无法连接到数据库

我使用SQL Server Management Studio生成数据库生成的备份文件恢复了本地开发数据库。我在该恢复上覆盖了本地数据库。从备份恢复数据库后无法连接到数据库

现在我无法使用SQL Squirrel连接到数据库。造成这种情况的原因以及如何解决这个问题？谢谢。

我在登录时出现错误“尝试打开SQL连接时发生意外错误”。

堆栈跟踪信息按钮显示如下：

缺少'GRANT's也许？ – fantaghirocco

您是否能够从SQL Server Management Studio内部进行连接？如果你不能那么你就知道这个问题可能是认证参数的一些变化。如果可以，请检查数据库名称，用户名，密码，主机和端口是否与服务器的相匹配。 –

有可能你有一个孤立用户。如果您的数据库用户未正确映射到相同名称的登录名，则服务器将无法将您连接到正确的数据库。你可以看到下面的文章以帮助排除故障

这是正确的。我有一个孤儿用户，并能够通过以下指示修复此问题：http://geekswithblogs.net/bullpit/archive/2010/04/21/user-already-exists-in-the-current-database--- sql-server.aspx问题解决了。 –
