使用 FetchXML 彙總
發行︰ 2017年1月
適用於： Dynamics 365 (online)、Dynamics 365 (on-premises)、Dynamics CRM 2016、Dynamics CRM Online
在 Microsoft Dynamics CRM 2015 和 Microsoft Dynamics 365 (線上)，FetchXML 包括群組和彙總功能，讓您計算加總、平均最小值、最大值和計數。
支援的彙總函數如下：
sum
avg
min
max
count(*)
count(屬性名稱)

關於彙總
若要建立彙總屬性，請將關鍵字 aggregate 設為 true，然後指定有效 entity name、attribute name和 alias (變數名稱)。 您也必須指定要執行的彙總類型。
下列範例顯示在 FetchXML 中的簡單彙總屬性。
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='entity name'>
<attribute name='attribute name' aggregate='count' alias='alias name'/>
</entity>
</fetch>"
使用彙總屬性的查詢結果與標準查詢結果不同。 別名值做為彙總結果的標記識別碼。
下列範例顯示一個彙總查詢結果的格式。
<resultset morerecords="0"'>
<result>
<alias>aggregate value</alias>
</result>
</resultset>"
下列範例顯示別名變數設定為 account_count 時的查詢結果。
<resultset morerecords="0"'>
<result>
<account_count>20</account_count>
</result>
</resultset>"
平均值
下列範例示範如何使用 avgaggregate 屬性。
// Fetch the average of estimatedvalue for all opportunities. This is the equivalent of
// SELECT AVG(estimatedvalue) AS estimatedvalue_avg ... in SQL.
System.Console.WriteLine("===============================");
string estimatedvalue_avg = @"
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='opportunity'>
<attribute name='estimatedvalue' alias='estimatedvalue_avg' aggregate='avg' />
</entity>
</fetch>";
EntityCollection estimatedvalue_avg_result = _serviceProxy.RetrieveMultiple(new FetchExpression(estimatedvalue_avg));
foreach (var c in estimatedvalue_avg_result.Entities)
{
decimal aggregate1 = ((Money)((AliasedValue)c["estimatedvalue_avg"]).Value).Value;
System.Console.WriteLine("Average estimated value: " + aggregate1);
}
System.Console.WriteLine("===============================");
計算平均值時使用 null 值的限制
Microsoft Dynamics 365 計算資料平均值時，不考量 null 值。 不過會使用零 (0)。
在下列範例中，使用下列資料，客戶 1 (兩個項目) 的平均值顯示為 250，而客戶 2 (兩個項目) 的平均值顯示為 125。
主題 |
潛在客戶 |
估計價值 |
|---|---|---|
商機 1 |
客戶 1 |
null |
商機 2 |
客戶 1 |
250 |
商機 3 |
客戶 2 |
0 |
商機 4 |
客戶 2 |
250 |
