Update to add DMF sys.dm_db_incremental_stats_properties in SQL Server 2014 or 2016

Summary

This update adds the Dynamic Management Function (DMF) sys.dm_db_incremental_stats_properties element to let you access properties of incremental statistics.

Note This update for DMF resembles the existing DMF sys.dm_db_stats_properties element. However, it also returns an additional column, partition_number, which provides the partition number for incremental statistics.

More Information

Incremental statistics are built on a partitioned table. This lets you maintain these statistics at the partition level instead of at the table level. Instead of having to scan the whole table, you can scan at only the partition level. This may significantly reduce the duration of your maintenance operations by updating only the statistics on the partitions that must be updated. Check out this blog post on TechNet for one such example.

This update is included in the following service pack for SQL Server:
