Dynamics CRM：爲系統用戶檢索多個約會

Question

我試圖通過RetrieveMultiple方法和查詢表達式獲取systemuser的所有約會。例如：

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（所有者，組織者，參加者需要，可選的與會者）的所有的約會？

或者是否必須檢索CRM的所有約會並添加條件以瞭解用戶是所有者，組織者，必需的還是可選的與會者？

最後，我使用SOAP Logger，它是生成SOAP請求的最佳方式嗎？

Answer 1

您需要使用appointment和systemuser之間的關係實體activitypointer。正如你在我的例子中看到的那樣，這會讓事情變得複雜一些。

至少有2種可能的方式來建立你所需的查詢：

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）您可以通過查詢systemuser：

1）正如你已經想通，您可以通過systemuserid篩選約會systemuserid並添加任命爲鏈接的實體（如在一個SQL查詢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), 
     }, 
    }, 
}; 

，關於對參與角色的過濾器，你就必須在participationtypemask添加一個條件在activitypointer：

// 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，我沒有收到任何的任命現在：

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);
