我希望能够计算并在我的联系表格上显示该联系人约会的最新实际结束日期。
以下查询显示了我如何针对帐户实体实现相同的功能。
使用 JavaScript 和 REST OData 查询 CRM 2011 AppointmentSet 时如何测试 d.data.results 中存在哪些数据
现在我尝试对联系人做同样的事情，但关于objectid 与任何联系人都不匹配。所以我在问我该怎么做。
我是否需要为组织者、可选参加者和必需参加者打开和展开每个派对列表？如果是这样，我将如何为此创建查询？使用 $expand 功能？
请帮助一个困扰的头脑！
撞！
好的，所以我已经在这个问题上工作了几天了。
我发现可以借助以下工具XRM Dynamics Tools来帮助生成我的 OData 查询代码来完成此任务。
本质上，我遇到的问题是了解联系人如何与约会相关联。一旦我了解约会的所有参与者都将包含在约会的“appointment_activity_parties”字段中，我就能够看到如何创建合适的查询来处理这个问题。
通过选择 activityid、actualEnd 字段并使用 Appointment_activity_parties 上的扩展功能，从该扩展字段中选择 PartyId 使我能够检查派对类型是否为联系人，派对的 contactId 是否与我们正在查看的当前联系人匹配。这样我就可以计算匹配的总数并记录该联系人完成约会的最近日期。
最后，我还将问题分解为 2 个查询。每年一个：当前和以前。我在联系表单中添加了三个新字段。两个保存 VisitsLastYear 和 VisitsThisYear 的整数，以及保存到 Appointment 的链接的查找，如以下屏幕截图所示：
我的代码如下：
/// <reference path="XrmPageTemplate.js" />
/// <reference path="JQuery.js" />
/// <reference path="SDK.REST.js" />
/// <reference path="json2.js" />
function HarrionAB_ContactForm_OnLoad() {
// get the contact id from the page
var contactId = Xrm.Page.data.entity.getId().replace("{", "").replace("}", "")
// if we got a value
if (contactId != "") {
var currentYear = new Date().getFullYear();
var query = "/AppointmentSet?"; // Appointments table
query += "$select=ActualEnd,ActivityId,appointment_activity_parties/PartyId"; // Select
query += "&$expand=appointment_activity_parties"; // Expand sub tables
query += "&$filter=ActivityTypeCode eq 'appointment' and StateCode/Value eq 1 and "; // Where
CountVisitsThisYear(query, currentYear);
CountVisitsLastYear(query, currentYear - 1);
}
}
function CountVisitsThisYear(query, currentYear) {
var start = currentYear.toString() + "-01-01T00:00:00";
var end = currentYear.toString() + "-12-31T00:00:00";
query += "ActualStart ge datetime'" + start + "' or ActualStart le datetime'" + start + "' and "; // Where
query += "ActualEnd ge datetime'" + end + "' or ActualEnd le datetime'" + end + "'"; // Where
// call function to execute the odata query
ExecuteVisitsThisYearQuery(query);
}
function CountVisitsLastYear(query, lastYear) {
var start = lastYear.toString() + "-01-01T00:00:00";
