            SQL Functions for Insights

            Use these aggregate, datetime, analytical, formatting, math and statistical, and boolean functions when you author calculated insights in Data 360. The Aggregatable column indicates whether a function's output can be rolled up across fewer dimensions when queried in segments or activations.

            Required Editions

            Note
            Note Streaming and real-time insights support only the SUM and COUNT aggregate functions.
            Available in: All Editions supported by Data 360. See Data 360 edition availability.

            Aggregatable and Non-Aggregatable Metrics

            Some functions produce metrics that can be rolled up or collapsed across dimensions. These are called aggregatable metrics. Functions such as SUM, COUNT, and AVG are examples of aggregatable metrics. You can query the result for any subset of the dimensions you defined when you created the insight.

            Other functions produce non-aggregatable metrics. Functions such as RANK, NTILE, and CASE are examples of non-aggregatable metrics. Because the result depends on all the dimensions at once, you can't reduce or collapse the metric to a smaller set of dimensions. When you query a non-aggregatable metric, you must provide values for all the dimensions that were defined when you created the insight.

            For example, if you create a metric called "Rank customers by total spend by product category and location" using the RANK function, you can't later query that rank for product category alone. When querying the metric, you must always specify both "Product Category" and "Location."

            SELECT
  ssot__SalesOrder__dlm.ssot__SalesChannelId__c AS channel__c,
  RANK() OVER (ORDER BY SUM(ssot__SalesOrder__dlm.ssot__GrandTotalAmount__c) ASC) AS spend_rank__c,
  UnifiedIndividual__dlm.ssot__Id__c AS unified_individual__c
FROM
  ssot__SalesOrder__dlm
  JOIN IndividualIdentityLink__dlm
    ON ssot__SalesOrder__dlm.ssot__SoldToCustomerId__c = IndividualIdentityLink__dlm.SourceRecordId__c
  JOIN UnifiedIndividual__dlm
    ON IndividualIdentityLink__dlm.UnifiedRecordId__c = UnifiedIndividual__dlm.ssot__Id__c
GROUP BY
  unified_individual__c,
  channel__c

            You can see whether a function produces a non-aggregatable metric in the object home screen of the Calculated Insights.
