This page provides the query to check whether statistics has been updated on SQL Server database.
Applicable in CAST Version
To check if the statistics have been updated, run the following query.
SELECT o.name, idx.name AS index_name, STATS_DATE(idx.OBJECT_ID, idx.index_id) AS statistics_update_date
FROM sys.indexes idx join sys.objects o
on idx.object_id = o.object_id
order by o.name, idx.name
Make sure the that the 'statistics_update_date' of the table indexes is between the last time it has been requested to process the update and the time you are doing the check
