Are you saying analyze table ... for table Or analyze table ... for table for all indexes ? Because in that case you will not be creating histograms on the columns and the last_analyzed column will not change in user_tab_columns. -----Original Message----- Smith, Ron L.

But for some reason the LAST ANALYZED column of USER_TAB_COLUMNS indicates the tables and indexes have not been analyzed in a year. This is Oracle 7.3.4. -- //www.freelists.org/webpage/oracle-l
