Question

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，当我从开发环境将web.config指向我的生产数据库时，我收到了这个错误。如果我指向测试数据库，那么一切正常。

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

仅在一个函数/查询＆＃39; GetEventViewAll＆＃39;上发生此错误，所有其他操作都在该数据库上运行。所以我认为功能＆＃39; GetEventViewAll＆＃39;返回更多行，因此我删除了该表上的所有行，但仍然收到该错误。

此错误仅在生产数据库上发生，而不是在生产环境中发生。我使用相同的机器，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DB（生产），然后收到错误。

有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'.

通过向函数添加Query-HasSideEffects属性解决了这个问题。

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

我将一个列表传递给该函数。该表从表中填写。测试数据库具有较少的值，生产数据库具有更多值，列表计数在生产数据库中更多。所以我收到了以下错误

The Maximum URI length of 2083 was exceeded

所以我把Query属性放到该函数来解决！

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