Subj:   Re: How much statistics to collect
From:   Martin O Brien

As far as I know dynamic random amp sampling is only used when there are no stats on the table. If there are stats on lets say the primary index then Teradata uses default stats for the rest of the columns ( which can be dangerous for "not very unique columns").
