    Last_ddl_time

    there are two databases. One is the backup of another database about 1 month ago.

    In this one month, I found out some tables got modified by checking dba_objects last_ddl_time.

    But when I use DBMS_METADATA.GET_DDL package to retrive ddl for those tables, I find no diff on those tables. I also checked dba_constraints and there is no difference on those tables also. Any idea what kind ddl used on those tables? To me, those tables are same.
