Question

我需要获取比7天还早的列表项并将其删除。我尝试使用caml查询，它在sharepoint 2010中效果很好，但是当我尝试在Sharepoint Online中使用它时，无论条件如何，它都会获取所有列表项并删除它。

    public static bool removeOldEntries(string listName, int offset)
    {
        bool successFlag = true;
        try
        {
            using (var context = new ClientContext(siteURL))
            {
                SecureString password = ToSecureString(pwd);
                context.Credentials = new SharePointOnlineCredentials(userName, password);
                Web web = context.Web;
                var list = context.Web.Lists.GetByTitle(listName);
                if (list != null)
                {
                    CamlQuery camlQuery = new CamlQuery();
                    camlQuery.ViewXml = "<Where><Leq><FieldRef Name='Modified'/><Value Type='DateTime'><Today OffsetDays='-" + offset + "'/></Value></Leq></Where>";
                    ListItemCollection collListItem = list.GetItems(camlQuery);
                    context.Load(collListItem, items => items.Include(
                                         item => item["ID"]));
                    context.ExecuteQuery();
                    if (collListItem.Count > 0)
                    {
                        foreach (ListItem oListItem in collListItem)
                        {
                            ListItem itemToDelete = list.GetItemById(int.Parse(oListItem["ID"].ToString()));
                            itemToDelete.DeleteObject();
                            context.ExecuteQuery();
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            successFlag = false;
        }
        return successFlag;
    }

在此先感谢您的帮助。

Answer 1

首先尝试在视图xml中添加标签

因此它应该看起来像

 camlQuery.ViewXml = "<Query><Where><Leq><FieldRef Name='Modified'/><Value Type='DateTime'><Today OffsetDays='-" + offset + "'/></Value></Leq></Where></Query>";

如果这样不利于尝试添加视图标签

 camlQuery.ViewXml = "<View><Query><Where><Leq><FieldRef Name='Modified'/><Value Type='DateTime'><Today OffsetDays='-" + offset + "'/></Value></Leq></Where></Query></View>";

Answer 2

您可以使用 PNP.PowerShell 模块。

$CreationDate = Get-Date "16.06.2021 20:04" -Format s 

Get-PnPListItem -List "Opportunities" -Query "<View><Query><Where><Eq><FieldRef Name='Created'/><Value Type='DateTime' IncludeTimeValue='FALSE'>$CreationDate</Value></Eq></Where></Query></View>"

caml查询无法在Sharepoint Online中正常运行
