Environment: Azure Cassandra API DB connected with CData Cassandra API DB
Created a simple report on a test table with 3 columns and 3 rows.
page - 1 contains Pie chart with summary totals
Page -2 contains Table to display details for the summary report in the page 1
When I added drillthrough option on a column the report, it is failing to retrieve the details on page 2 and
resulting an error (retrieved from the CData driver logs)
[Connection: 2] Query Failed: [SELECT count(1) AS "C1" FROM (SELECT "email", "name", "userid" FROM "CData"."kspace2"."usertest" WHERE "name" = 'kkkkkk') AS "ITBL"]. Error: The connection '2' query failed to execute query 'SELECT count(1) AS "C1" FROM (SELECT "email", "name", "userid" FROM "CData"."kspace2"."usertest" WHERE "name" = 'kkkkkk') AS "ITBL"': The CQL error message is ''count' is not supported yet.'..
My question is why POWER BI is building a query with a count, when it is required display only the details (all columns and rows for the summary report).
Without DrillThrough both the pages are getting refreshed without error.
I see the problem with the Drillthrough option trying to send a query with Count function, which is not supported in Azure Cassandra API database.
Please let me know how to resolve this issue.
Thanks in advance
