System.ServiceModel.DomainServices.Client.DomainOperationException：查询的加载操作失败答案

【问题描述】：

我在 WCF+Silverlight+RIA 服务应用程序中收到以下错误。它只发生在生产数据库上。

我将生产数据库复制到我的开发机器上，当我从开发环境将 web.config 指向我的生产数据库时出现该错误。如果我指向测试数据库，那么一切正常。

所以我认为数据库中存在一些不匹配问题，所以我尝试比较测试和生产数据库，所有数据库结构都相同。

此错误仅发生在一个函数/查询“GetEventViewAll”上，所有其他操作都在该数据库上运行。所以我认为函数“GetEventViewAll”返回更多行，所以我删除了该表上的所有行，但仍然出现该错误。

此错误仅发生在生产数据库上，而不是生产环境。我正在使用相同的机器，相同的代码，相同的 VS2010。我只是在 web.config 上进行更改以指向其他数据库（生产）然后出错。

谁能告诉我我错过了什么或需要做什么？

VS2010输出窗口的错误是：{System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation failed for query 'GetEventViewAll'.

【问题讨论】：

检查您是否可以访问 prod DB 服务器
@K.B 我确实备份了 prod 数据库并在我的开发 PC 中恢复。当我连接恢复的 DB(prod DB) 时，我只在特定功能上收到该错误，其他操作工作正常。
您是否对数据库架构进行了任何更改
@K.B 是的，我做了一些改变，我也在 prod DB 中做了同样的事情。我使用 dbdiff 工具比较了两个结构相同的数据库。
@K.B 感谢 KB，我找到了解决方案。

【解决方案1】：

通过在函数中添加 Query-HasSideEffects 属性解决。

[Query(HasSideEffects = true)]    //<--- this line solved the problem
public IQueryable<EventView> GetEventView(List<string> siteName)
{
 .....
}

我向该函数传递了一个列表。该列表是从表格中填写的。测试数据库的值较少，生产数据库的值更多，生产数据库中的列表计数更多。所以我得到了以下错误

The Maximum URI length of 2083 was exceeded

所以我把 Query 属性放到那个函数来解析！

【讨论】：

（在 Silverlight 中）如果添加属性 [Query(HasSideEffects = true)]。添加 .Where() 或 .OrderBy() 时，查询加载失败。你解决了吗？示例：_domainServiceAtClient.Load(query.Where(p=>p.ID = _id))。
更新：部署web时出错。
