Sentry One Newsletters The bi-weekly newsletter keeps you up to speed on the most recent blog posts and forum discussions in the SQL Server community.e News is a bi-monthly newsletter with fun information about Sentry One, tips to help improve your productivity, and much more.The last several releases of SQL Server have introduced a slew of new features, as well as improvements in existing functionality.0 index(es)/statistic(s) have been updated, 1 did not require update.Updating [dbo].[Test Memory2] [PK__Test Memo__3214EC07D3DC52DE], update is not necessary… 2 index(es)/statistic(s) have been updated, 0 did not require update.In general sampling (as opposed to full scans) kicks in when we have about 8MB of data in the table (or about 1000 pages).
After all, statistics still get created the same way, they still tell you about the distribution of data, they're still used by the Query Optimizer… The basic function of statistics remains the same – but how they're used by the Query Optimizer does change depending on the Cardinality Estimator you're using.
This is another method you might use for manually updating statistics (perhaps as part of a scheduled maintenance job).
This system stored procedure can be used for updating all of the statistics objects in a database: This stored procedure iterates through your database using a WHILE loop and executes the UPDATE STATISTICS command as it goes.
Equally though if you’re updating statistics in a quieter time (e.g.
overnight) you may feel you can afford the extra time for the full scans.
