为多个输入查询 SharePoint 列表时出现 CAML 错误

Question

我有一个 CAML 查询，它从 SharePoint 列表中检索数据。它通过 1 个输入，但当有 2 个或更多时失败。

错误：

Microsoft.SharePoint.SPException: One or more field types are not installed properly. Go to the list settings page to delete these fields. ---> System.Runtime.InteropServices.COMException: One or more field types are not installed properly. Go to the list settings page to delete these fields.

经过研究，可能的原因可能是 SharePoint 列不匹配 InternalName。但是，查询设法针对 1 个输入执行，而不是 2 个或更多输入。

根据下面的查询示例，我对 FAIL 个案例的格式是否有误？

1.通过：

<Where>
    <And>
        <Eq>
            <FieldRef Name="Header1Ref"/><Value Type="Text">H1</Value>
        </Eq>
        <Neq>
            <FieldRef Name ="ContentType"/><Value Type="Text">Document</Value>
        </Neq>
    </And>
</Where>

2。失败：

<Where>
    <And>
        <Eq>
            <And>
                <Or>
                    <Eq>
                        <FieldRef Name="Header1Ref"/><Value Type="Text">H1</Value>
                    </Eq>
                    <Eq>
                        <FieldRef Name="Header1Ref"/><Value Type="Text">H2</Value>
                    </Eq>
                </Or>
                    <Neq>
                        <FieldRef Name ="ContentType"/><Value Type="Text">Document</Value>
                    </Neq>
            </And>
        </Eq>
    </And>
</Where>

3。失败：

<Where>
    <And>
        <Eq>
            <And>
                <Or>
                    <FieldRef Name="Header1Ref"/><Value Type="Text">H1</Value>
                    <FieldRef Name="Header1Ref"/><Value Type="Text">H2</Value>
                </Or>
                <Neq>
                    <FieldRef Name ="ContentType"/><Value Type="Text">Document</Value>
                </Neq>
            </And>
        </Eq>
        <Neq>
            <FieldRef Name ="ContentType"/><Value Type="Text">Document</Value>
        </Neq>
    </And>
</Where>

Answer 1

是CAML查询的问题，我将代码修改如下，供大家参考。

string siteUrl = "http://sp2013";
string listTitle = "DL";
string viewName="Test";

using (SPSite site = new SPSite(siteUrl))
{
    using (SPWeb web = site.OpenWeb())
    {
        SPList list = web.Lists[listTitle];
        SPView view=list.Views[viewName];
        string orQuery = "<Or><Eq><FieldRef Name=\"Header1Ref\"/><Value Type=\"Text\">H1</Value></Eq><Eq><FieldRef Name=\"Header1Ref\"/><Value Type=\"Text\">H2</Value></Eq></Or>";
        string subQuery = String.Format("<Neq><FieldRef Name =\"ContentType\"/><Value Type=\"Text\">{0}</Value></Neq>", "Document");
        string queryText = String.Format("<Where><And>{0}{1}</And></Where>", orQuery, subQuery);
        var query = new SPQuery(view)
        {
            Query = queryText,
            ViewAttributes = "Scope=\"RecursiveAll\"",
            ViewFields = @"<FieldRef Name='RecordTitle'/>",
        };

        SPListItemCollection items = list.GetItems(query);
        foreach (SPListItem item in items)
        {
            Console.WriteLine(item["RecordTitle"]);
        }
        Console.ReadKey();
    }
}

CAML 查询如下。

<Where>
    <And>
        <Or>
            <Eq><FieldRef Name="Header1Ref"/><Value Type="Text">H1</Value></Eq>
            <Eq><FieldRef Name="Header1Ref"/><Value Type="Text">H2</Value></Eq>
        </Or>
        <Neq>
            <FieldRef Name="ContentType"/><Value Type="Text">Document</Value>
        </Neq>
    </And>
</Where>
