| Hi allI've read the post from somewhere that if you do REINDEX, that the statistic gets rebuild by default? Is this true? The sampling value is default which 10%? Also, does this this the same case if you do INDEXDEFRAG?Thanks |

| Reindex will update the stats with 100%. If you do an UPDATE STATS without mentioning the percentage it will update the stats with a 10% sample data.Dinakar Nethi************************Life is short. Enjoy it.************************http://weblogs.sqlteam.com/dinakar/ |
