解决方案
确保帐户下运行的过程，其中承载服务具有访问权限的数据库。例如如果IIS帐户运行该服务托管必须登陆到数据库服务器，它必须有权做一切必要的业务数据库中的应用程序池。
I could be able to call it in my own server and it works but the problem occurs when I host wcf service in IIS. The details of the error are the following...
Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.
Stack Trace Error Details
The server was unable to process the request due to an internal error.
For more information about the error, either turn on
IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute
or from the <serviceDebug> configuration behavior) on the server in
order to send the exception information back to the client, or turn on
tracing as per the Microsoft .NET Framework 3.0 SDK documentation and
inspect the server trace logs.

解决方案
Ensure that account running your process where the service is hosted has access rights to the database. For example in case of IIS the account running the application pool where the service is hosted must have login to database server and it must have permissions to do all necessary operations in your database.
