Database updating statistics does race matter in dating

If you absolutely must update the statistics and rebuild the indexes and you’re not going to try to tightly control exactly which indexes and tables you do this on, then the best practice would be to update the statistics first and then rebuild the indexes second. The keyword and tricky phrase that you have to look at is WITH FULL SCAN.That indicates that the full data set is used to create/update the statistics.Now when you reorganize an index, no modifications of any kind are made to the statistics.So if you’ve had enough modifications to the data that you feel you should also update the statistics, go ahead and do it for indexes that you’ve reorganized because you won’t be hurting any other work.
