Use FetchXML aggregation
Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
In Microsoft Dynamics CRM 2015 and Microsoft Dynamics 365 (online), FetchXML includes grouping and aggregation features that let you calculate sum, average min, max and count.
The following aggregate functions are supported:
sum
avg
min
max
count(*)
count(attribute name)

About aggregation
To create an aggregate attribute, set the keyword aggregate to true, then specify a valid entity name, attribute name, and alias (variable name). You must also specify the type of aggregation you want to perform.
The following example shows a simple aggregate attribute in FetchXML.
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='entity name'>
<attribute name='attribute name' aggregate='count' alias='alias name'/>
</entity>
</fetch>"
The result of a query with an aggregate attribute is different from the results of a standard query. The alias value is used as the tag identifier for the aggregate result.
The following example shows the format of the result of an aggregate query.
<resultset morerecords="0"'>
<result>
<alias>aggregate value</alias>
</result>
</resultset>"
The following example shows the results of a query when the alias variable is set to account_count.
<resultset morerecords="0"'>
<result>
<account_count>20</account_count>
</result>
</resultset>"
Avg
The following example shows how to use the avg aggregate attribute.
// 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("===============================");
Limitation with null values while computing average
Null values are not considered when Microsoft Dynamics 365 computes the average of data. However, zero (0) is used.
In the following example, with the following data, the average for Account 1 (two entries) is shown as 250 whereas the average for Account 2 (two entries) is shown as 125.
Topic |
Potential Customer |
Estimated value |
|---|---|---|
Opportunity 1 |
Account 1 |
null |
Opportunity 2 |
Account 1 |
250 |
Opportunity 3 |
Account 2 |
0 |
Opportunity 4 |
Account 2 |
250 |
Count
The following example shows how to use the count aggregate attribute.
// *****************************************************************************************************************
// FetchXML opportunity_count Aggregate 2
// *****************************************************************************************************************
// Fetch the count of all opportunities. This is the equivalent of
// SELECT COUNT(*) AS opportunity_count ... in SQL.
string opportunity_count = @"
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='opportunity'>
<attribute name='name' alias='opportunity_count' aggregate='count'/>
</entity>
</fetch>";
EntityCollection opportunity_count_result = _serviceProxy.RetrieveMultiple(new FetchExpression(opportunity_count));
foreach (var c in opportunity_count_result.Entities)
{
Int32 aggregate2 = (Int32)((AliasedValue)c["opportunity_count"]).Value;
System.Console.WriteLine("Count of all opportunities: " + aggregate2);
}
System.Console.WriteLine("===============================");
CountColumn
The following example shows how to use the countcolumn aggregate attribute to count columns.
// *****************************************************************************************************************
// FetchXML opportunity_colcount Aggregate 3
// *****************************************************************************************************************
// Fetch the count of all opportunities. This is the equivalent of
// SELECT COUNT(name) AS opportunity_count ... in SQL.
string opportunity_colcount = @"
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='opportunity'>
<attribute name='name' alias='opportunity_colcount' aggregate='countcolumn'/>
</entity>
</fetch>";
EntityCollection opportunity_colcount_result = _serviceProxy.RetrieveMultiple(new FetchExpression(opportunity_colcount));
foreach (var c in opportunity_colcount_result.Entities)
{
Int32 aggregate3 = (Int32)((AliasedValue)c["opportunity_colcount"]).Value;
System.Console.WriteLine("Column count of all opportunities: " + aggregate3);
}
System.Console.WriteLine("===============================");
Count distinct columns
The following example shows how to use the countcolumn aggregate attribute with the distinct attribute to count distinct columns.
// *****************************************************************************************************************
// FetchXML opportunity_distcount Aggregate 4
// *****************************************************************************************************************
// Fetch the count of distinct names for opportunities. This is the equivalent of
// SELECT COUNT(DISTINCT name) AS opportunity_count ... in SQL.
string opportunity_distcount = @"
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='opportunity'>
<attribute name='name' alias='opportunity_distcount' aggregate='countcolumn' distinct='true'/>
</entity>
</fetch>";
EntityCollection opportunity_distcount_result = _serviceProxy.RetrieveMultiple(new FetchExpression(opportunity_distcount));
foreach (var c in opportunity_distcount_result.Entities)
{
Int32 aggregate4 = (Int32)((AliasedValue)c["opportunity_distcount"]).Value;
System.Console.WriteLine("Distinct name count of all opportunities: " + aggregate4);
}
System.Console.WriteLine("===============================");
Max
Null values are not considered when Microsoft Dynamics 365 computes the maximum of data. However, zero (0) is used.
The following example shows how to use the max aggregate attribute.
// *****************************************************************************************************************
// FetchXML estimatedvalue_max Aggregate 5
// *****************************************************************************************************************
// Fetch the maximum estimatedvalue of all opportunities. This is the equivalent of
// SELECT MAX(estimatedvalue) AS estimatedvalue_max ... in SQL.
string estimatedvalue_max = @"
<fetch distinct='false' mapping='logical' aggregate='true'>
<entity name='opportunity'>
<attribute name='estimatedvalue' alias='estimatedvalue_max' aggregate='max' />
</entity>
</fetch>";
EntityCollection estimatedvalue_max_result = _serviceProxy.RetrieveMultiple(new FetchExpression(estimatedvalue_max));
foreach (var c in estimatedvalue_max_result.Entities)
{
decimal aggregate5 = ((Money)((AliasedValue)c["estimatedvalue_max"]).Value).Value;
System.Console.WriteLine("Max estimated value of all opportunities: " + aggregate5);
}
System.Console.WriteLine("===============================");
Min
Null values are not considered when Microsoft Dynamics 365 computes the minimum of data. However, zero (0) is used.
The following example shows how to use the min aggregate attribute.

// *****************************************************************************************************************
// Fetch the minimum estimatedvalue of all opportunities. This is the equivalent of

<attribute name='estimatedvalue' alias='estimatedvalue_min' aggregate='min' />
</entity>
</fetch>";
EntityCollection estimatedvalue_min_result = _serviceProxy.RetrieveMultiple(new FetchExpression(estimatedvalue_min));
foreach (var c in estimatedvalue_min_result.Entities)
{

System.Console.WriteLine("Minimum estimated value of all opportunities: " + aggregate6);
}
System.Console.WriteLine("===============================");

<attribute name='estimatedvalue' alias='estimatedvalue_sum' aggregate='sum' />
</entity>
</fetch>";
EntityCollection estimatedvalue_sum_result = _serviceProxy.RetrieveMultiple(new FetchExpression(estimatedvalue_sum));
foreach (var c in estimatedvalue_sum_result.Entities)
