dbcc dbredindex/Alter index (or) update stats which should run first?

Statistics created manually or by auto create stats will not be updated by ALTER INDEX ALL ON table.

If you run dbcc dbredindex on a table , it will update stats on index indx with 100% sampling, but the stats created by auto create stats and manually created stats are updated with default sampling percentage.

Now choose your self.
