Re: how to create a histogram on column group

Hi Nenad

Are you saying that this kind of thing doesn't work properly?

SELECT

       dbms_stats.create_extended_stats
       (ownname   => user
       ,tabname   => 'T1'
       ,extension => '(T1_COL_NAME,T1_COL_VALUE)'
      )

DBMS_STATS.CREATE_EXTENDED_STATS(

      dbms_stats.gather_table_stats
            (user


           ,'T1'

           ,method_opt    => 'for columns SYS_STUE3EBVNLB6M1SYS3A07$LD52


size skewonly'


           ,cascade       => true


           ,no_invalidate => false


            );

Or probably you want something generic applied on a larger scale?

Best regards
Mohamed
