Dynamics CRM：為系統用戶檢索多個約會

Question

我正在嘗試使用RetrieveMultiple方法和查詢表達式來獲取系統用戶的所有約會。 范例：

WhoAmIRequest userRequest = new WhoAmIRequest();
WhoAmIResponse userResponse = (WhoAmIResponse)_serviceProxy.Execute(userRequest);

QueryExpression qe = new QueryExpression();
qe.EntityName = "systemuser";

...
slos.RetrieveMultiple(qe);

我可以從systemuser實體檢索systemuser的所有約會（所有者，組織者，必需的與會者，可選的與會者）嗎？

還是我必須檢索CRM的所有約會並添加條件才能知道用戶是所有者，組織者，必需參與者還是可選參與者？

最后，我正在使用SOAP Logger，這是生成SOAP請求的最佳方法嗎？

Answer 1

您將需要使用appointment和systemuser之間的關系實體activitypointer systemuser 。 正如您在我的示例中看到的那樣，這使事情有些復雜。

至少有兩種可能的方式來構建所需的查詢：

1）如您所料，您可以按systemuserid過濾約會：

var qe = new QueryExpression
{
    EntityName = "appointment",
    ColumnSet = new ColumnSet("subject"),
    LinkEntities =
    {
        new LinkEntity
        {
            EntityAlias = "ap",
            JoinOperator = JoinOperator.Inner,
            Columns = new ColumnSet(false),
            LinkFromEntityName = "appointment",
            LinkFromAttributeName = "activityid",
            LinkToEntityName = "activityparty",
            LinkToAttributeName = "activityid",
            LinkCriteria = new FilterExpression
            {
                Conditions =
                {
                    new ConditionExpression("partyid", ConditionOperator.Equal, userid),
                },
            },
        },
    },
};

2）您可以通過systemuserid查詢systemuser並將約會添加為鏈接的實體（例如sql查詢中的JOIN）：

var qe2 = new QueryExpression
{
    EntityName = "systemuser",
    ColumnSet = new ColumnSet(false),
    LinkEntities =
    {
        new LinkEntity
        {
            EntityAlias = "ap",
            Columns = new ColumnSet(false),
            JoinOperator = JoinOperator.Inner,
            LinkFromEntityName = "systemuser",
            LinkFromAttributeName = "systemuserid",
            LinkToEntityName = "activityparty",
            LinkToAttributeName = "partyid",
            LinkEntities =
            {
                new LinkEntity
                {
                    EntityAlias = "a",
                    Columns = new ColumnSet("subject"),
                    JoinOperator = JoinOperator.Inner,
                    LinkFromEntityName = "activityparty",
                    LinkFromAttributeName = "activityid",
                    LinkToEntityName = "appointment",
                    LinkToAttributeName = "activityid",
                },
            },
        },
    },
    Criteria = new FilterExpression
    {
        Conditions =
        {
            new ConditionExpression("systemuserid", ConditionOperator.Equal, userid),
        },
    },
};

關於參與角色的過濾器，您必須在activitypointer的participationtypemask上添加一個條件：

// user is Organizer, Owner, required or optional Attendee
ConditionExpression("participationtypemask", ConditionOperator.In, new int[] { 5, 6, 7, 9 }),

Answer 2

有了這個表達，我現在沒有收到任何約會：

QueryExpression qe = new QueryExpression
{
    EntityName = "appointment",
    ColumnSet = new ColumnSet("activityid", "subject", "scheduledstart", "scheduledend", "location", "description"),
    Criteria = new FilterExpression
    {
        FilterOperator = LogicalOperator.And,
        Conditions = 
        {
            new ConditionExpression("scheduledend", ConditionOperator.GreaterThan, startTime),
            new ConditionExpression("scheduledstart", ConditionOperator.LessThan, endTime)
         }
     },
     LinkEntities = 
     {
         new LinkEntity
         {
             LinkFromEntityName = "activitypointer",
             LinkFromAttributeName = "activityid",
             LinkToEntityName = "activityparty",
             LinkToAttributeName = "activityid",
             LinkCriteria = new FilterExpression
             {
                 FilterOperator = LogicalOperator.And,
                 Conditions = 
                 {
                     new ConditionExpression("participationtypemask", ConditionOperator.In, new int[] { 5, 6, 7, 9 }),
                     new ConditionExpression("partyid", ConditionOperator.Equal, userResponse.UserId)

                 }
             }
         },
         new LinkEntity
         {
             EntityAlias = "requiredattendees",
             Columns = new ColumnSet(false),
             JoinOperator = JoinOperator.Inner,
             LinkFromEntityName = "activitypointer",
             LinkFromAttributeName = "activityid",
             LinkToEntityName = "activityparty",
             LinkToAttributeName = "activityid",
             LinkCriteria = new FilterExpression
             {
                 Conditions = 
                 {
                     new ConditionExpression("participationtypemask", ConditionOperator.Equal, 5)

                 }
             },
             LinkEntities =
             {
                 new LinkEntity
                 {
                     EntityAlias = "contact",
                     Columns = new ColumnSet("fullname"),
                     JoinOperator = JoinOperator.Inner,
                     LinkFromEntityName = "activityparty",
                     LinkFromAttributeName = "activityid",
                     LinkToEntityName = "contact",
                     LinkToAttributeName = "contactid"
                 },
             }
         }
     }
 };

 qe.Distinct = true;

 slos.RetrieveMultiple(qe);
