Aggregate data using OData

  • Чланак

Use the $apply option to aggregate and group your data.

The aggregate functions are limited to a collection of 50,000 records. Further information around using aggregate functionality with Dataverse can be found here: Aggregate data using FetchXml.

You can find more information about OData data aggregation here: OData extension for data aggregation version 4.0. Dataverse supports only a subset of these aggregate methods.

Note

  • groupby with datetime values is not supported.

  • $orderby with aggregate values is not supported. This will return the error: The query node SingleValueOpenPropertyAccess is not supported.

Following are some examples:

Distinct column values

OData doesn't have a $distinct query option to restrict results to unique values. Instead, use the $apply system query option with the groupby transformation. This returns distinct values for each property.

Request:

GET [Organization URI]/api/data/v9.2/accounts?$apply=groupby((statecode,statuscode,accountcategorycode))
Accept: application/json  
OData-MaxVersion: 4.0  
OData-Version: 4.0
Prefer: odata.include-annotations="OData.Community.Display.V1.FormattedValue"

Response:

HTTP/1.1 200 OK  
Content-Type: application/json; odata.metadata=minimal  
OData-Version: 4.0  
Preference-Applied: odata.include-annotations="OData.Community.Display.V1.FormattedValue"

{
   "@odata.context": "[Organization URI]/api/data/v9.2/$metadata#accounts",
   "value": [
      {
         "statuscode": 1,
         "statecode": 0
      },
      {
         "statuscode": 1,
         "statecode": 0,

OData aggregation limitations

This section describes capabilities that are available using aggregation with FetchXml that are not currently available using OData.

Get distinct number with CountColumn

You can't get a distinct number of values using CountColumn with OData. Learn about distinct column values using FetchXml

Time zone when grouping by date

Grouping by parts of a date always uses UTC time and there is no way to specify that the user's time zone should be used instead available in FetchXml

Row aggregate

When a table has a hierarchical relationship defined, you can't return a row aggregate on the lookup column for the hierarchical relationship. Learn about row aggregates using FetchXml

Per query limit

There is no way to specify a configurable aggregate limit. Learn about per query limits using FetchXml

Limitations

Queries that return aggregate values are limited to 50,000 records. This limit helps maintain system performance and reliability. If the filter criteria in your query returns more than 50,000 records, you get the following error:

Number: -2147164125
Code: 8004E023
Message: AggregateQueryRecordLimit exceeded. Cannot perform this operation.
Client error message: The maximum record limit is exceeded. Reduce the number of records.

To avoid this error, add appropriate filters to your query to make sure it doesn't evaluate more than 50,000 records. Then run your query multiple times and combine the results. Appropriate filters depend on the nature of your data, but they could be a date range or a subset of values in a choice column.
