Create a trended report of events
This document provides an example of the SQL required to create a trended report of events by day over a specific date range. With ÃÛ¶¹ÊÓƵ Experience Platform Query Service, you can write queries that use Experience Events to capture a variety of use cases. Experience Events are represented by the Experience Data Model (XDM) ExperienceEvent class, which captures an immutable and non-aggregated snapshot of the system when a user interacts with a website or service. Experience Events can even be used for time-domain analysis. See the next steps section for more use cases that involve Experience Events to generate visitor reports.
Reports give you access to your Platform data to benefit your organization’s strategic business insights. With these reports, you can examine your Platform data in a variety of ways, display key metrics in easy-to-understand formats, and share the resulting insights.
More information about XDM and Experience Events can be found in the XDM System overview. By combining Query Service with Experience Events, you can effectively track behavioral trends amongst your users. The following document provides examples of queries involving Experience Events.
Objectives
The following example creates a trended report of events over a specified date range, grouped by date. Specifically, this SQL example sums up various analytics values as A, B, and C, and then sums up the number of times parkas have been viewed over the period of a month.
The timestamp column found in Experience Event datasets is in UTC format. The example uses the from_utc_timestamp() function to transform the timestamp from UTC to EDT and then uses the date_format() function to isolate the date from the rest of the timestamp.
SELECT
date_format( from_utc_timestamp(timestamp, 'EDT') , 'yyyy-MM-dd') as Day,
SUM(web.webPageDetails.pageviews.value) as pageViews,
SUM(_experience.analytics.event1to100.event1.value) as A,
SUM(_experience.analytics.event1to100.event2.value) as B,
SUM(_experience.analytics.event1to100.event3.value) as C,
SUM(
CASE
WHEN _experience.analytics.customDimensions.evars.evar1 = 'parkas'
THEN 1
ELSE 0
END) as viewedParkas
FROM your_analytics_table
WHERE TIMESTAMP >= to_timestamp('2019-03-01') AND TIMESTAMP <= to_timestamp('2019-03-31')
GROUP BY Day
ORDER BY Day ASC, pageViews DESC;
The results of this query can be seen below.
