存储过程返回未知执行结果未知

Question

调用托管环境中托管的工作流服务时,我收到以下错误.

Stored procedure returned unknown execution result Unknown.

Server stack trace: 
   at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc)
   at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)
   at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
   at IWorkflow.InvokeWorkflowRequest(String id)
   at WorkflowClient.InvokeWorkflowRequest(String id)

我的配置文件

  <system.serviceModel>
    <services>
      <service name="WorkflowService">
       <endpoint binding="basicHttpBinding" contract="IWorkflow"  />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <sqlWorkflowInstanceStore connectionString="Data Source=.;Initial Catalog=Store;Integrated Security=True;Asynchronous Processing=True"  />
      </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

本地服务工作正常,甚至指向我的暂存数据库.我会感激任何帮助.

当没有DefinitionIdentity持久保存新实例时,我在Workflow Foundation 4.5中遇到了类似的问题.

抛出了"存储过程返回未知执行结果未知"的异常,并且没有给出内部异常.

抛出异常是因为SaveInstance过程返回99并且是由表[System.Activities.DurableInstancing]中缺少的行引起的.[DefinitionIdentityTable].

您可以使用以下sql脚本重新创建缺少的行:

INSERT [System.Activities.DurableInstancing].[DefinitionIdentityTable]([SurrogateIdentityId],[DefinitionIdentityHash],[DefinitionIdentityAnyRevisionHash],[Name],[Package],[Build],[Major],[Minor],[Revision])VALUES (1,N'00000000-0000-0000-0000-000000000000',N'00000000-0000-0000-0000-000000000000',NULL,NULL,NULL,NULL,NULL,NULL)

我希望它对某人有帮助
