Question

我在SharePoint网站中查询多个任务列表。我可以检索结果，直到我设置Query属性并指定OrderBy子句。详细的例外和代码粘贴在下面。感谢任何帮助

   private void doTasks(SPWeb currentWeb, SPSiteDataQuery q)
    {

        q.Query =
             "<OrderBy>" +
             "   <FieldRef Name='Priority' />" +
             "   <FieldRef Name='DueDate' />" +
             "</OrderBy>";


        // Specify the view fields.
        q.ViewFields = "<FieldRef Name='Title' Type='Text'/>";
        q.ViewFields += "<FieldRef Name='AssignedTo' Type='User' Nullable='TRUE' />";
        q.ViewFields += "<FieldRef Name='PercentComplete' Type='Number' Nullable='TRUE'/>";
        results = currentWeb.GetSiteData(q);

        if (results.Rows.Count > 0)
        {
                 //blah!
        }
    }

在迁移过程中，一些页面布局使用SPSiteDataQuery在不同的Web上查询ContentTypes以获取内容。该代码在SP2007中运行良好，但在SP2010中它抛出异常，如下所述：

<强>解决方案

确保您使用的订单字段包含在SPSiteDataQuery.ViewFields属性中。就这么简单！

Answer 2

在OrderBy中包装<Query></Query>子句。

Answer 3

如果删除AssignedTo和PercentComplete FieldRef，它是否有效？我问，因为如果您查询站点中的所有列表，大多数将不包含AssignedTo和PercentComplete字段。这可能会导致错误。

q.Lists的价值是多少？如果您尚未设置q.Lists，请尝试：

q.Lists = "<Lists ServerTemplate=\"107\" />"

如果其他人遇到类似的问题：在我发现CAML查询的最后一行不能是空行之前，我花了两个小时。换句话说，在CAML查询结束时不得有任何换行符。删除换行符立即解决了问题。
