Updating statistics sql server 2016
Be aware that it can take some time to run depending upon table or database size.Ideally, you would run this on a regular basis for one of the following reasons:• You suspect that you are seeing incorrect values returned for sp_spaceused.Also worth mentioning again is how easy Azure makes this for you.This is also a good time to mention that sometimes it is worth running “production parallel”, where you have two systems running at the same time, both are considered production.The use of a POC test system saves you a lot of time with the ‘after’ phase.
I’m the type of person that would rather be safe than sorry.• Your database has a high volume of DDL statements (CREATE, ALTER, or DROP).This is a MUST for any migration or upgrade checklist: This command will update the statistics for all the tables in your database.You want to do this before the server is handed over to the end users for further testing. For databases created prior to SQL 2005 (and you *know* they are still out there), this step is important.This post will provide you a checklist of items to review after the upgrade is complete. For databases created in SQL 2005 and later, the DATA_PURITY check is done automatically with a regular CHECKDB.
