我意识到那里有很多“解决方案”，但没有一个能解决我的问题。

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

我的数据库连接在我的开发服务器上，但没有连接到生产机器上。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;" />

这是我收到的信息：

我尝试通过使用直接连接将 EF 从等式中删除，但仍然得到相同的消息，但堆栈略有不同。

开始扯我的头发。帮助！

让我坚持。请尝试以这种方式 DROP 和 CREATE login 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

最明显的解释是最简单的：您在该数据库服务器上为该帐户设置了错误的密码。我假设你已经验证了

  1. 该帐户存在于 SQL 2008 服务器上；
  2. 您可以使用您使用的密码登录吗？

另外，你为什么在生产机器上指的是“localhost”？您的数据库与您的 Web 服务器在同一台机器上吗？（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，而不是网络上的机器名称。

确保PingtreeUser具有数据库的必要权限Pingtree。

  1. 在 MS SQL Server Management Studio 中，使用sa帐户或通过 Windows 身份验证登录
  2. 展开.\SQLEXPRESS > Security > Logins文件夹
  3. 双击PingtreeUser
  4. 确保这Default database是Pingtree
  5. 点击User Mapping左侧
  6. 确保Pingtree检查数据库
  7. 在底部，检查db_owner
  8. 点击Ok

这应该提供PingtreeUser访问Pingtree数据库的必要权限。
