Question

我意识到那里有很多“解决方案”，但没有一个解决了我的问题。

我最近创建了一个网站，并在生产机器上使用iis7.5 / sql server 2008.

我的数据库在我的开发服务器上连接，但不在产品上。我的开发机器是sql express 2008。

这是连接：

<add name="PingtreeEntities"
  providerName="System.Data.EntityClient"
  connectionString="metadata=
  res://*/;
  provider=System.Data.SqlClient;
  provider connection string=&quot;
  Data Source=localhost;
  Initial Catalog=Pingtree;
  Integrated Security=False;
  User Id=PingtreeUser;
  Password=*********;
  MultipleActiveResultSets=True&quot;" />

这是我得到的消息：

[SqlException (0x80131904): Cannot open database "Pingtree" requested by the login. The login failed.

我尝试使用直接连接删除等式中的EF，但仍然得到相同的消息，堆栈略有不同。

开始撕掉我的头发。救命啊！

让我坚持。请尝试以这种方式DROP和CREATE登录和db-user：

（请注意，您必须将密码更改为您使用的密码）

-- Drop & recreate login
USE [master]
GO
IF EXISTS(SELECT * FROM sys.syslogins WHERE name = N'PingtreeUser')
    DROP LOGIN [PingtreeUser];
GO
CREATE LOGIN [PingtreeUser]
    WITH
        PASSWORD=N'password',
        DEFAULT_DATABASE=[Pingtree],
        CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO

-- Drop & recreate db-user
USE [Pingtree]
GO
IF  EXISTS (SELECT * FROM sys.database_principals WHERE name = N'PingtreeUser')
    DROP USER [PingtreeUser];
GO
CREATE USER [PingtreeUser] FOR LOGIN [PingtreeUser]
GO
EXEC sp_addrolemember N'db_owner', N'PingtreeUser'
GO

Answer 2

最明显的解释是最简单的：您在该数据库服务器上拥有该帐户的错误密码。我假设你已经验证了

该帐户存在于SQL 2008服务器上;
您可以使用您正在使用的密码登录吗？

另外，为什么在生产机器上提到“localhost”？您的数据库与Web服务器在同一台计算机上吗？（不一定是个好主意。）无论哪种方式，您都需要使用数据库服务器名称，而不是网络上的计算机名称。

Answer 3

确保PingtreeUser具有Pingtree数据库的必要权限。

在MS SQL Server Management Studio中，使用sa帐户或Windows身份验证
展开.\SQLEXPRESS > Security > Logins文件夹
双击PingtreeUser
确保Default database为Pingtree
点击左侧的User Mapping
确保选中Pingtree数据库
点击底部，查看db_owner
点击Ok

这应该为PingtreeUser提供访问Pingtree数据库的必要权限。

部署后无法访问远程数据库
