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.

what kind of backup did u take?
-
no, unless you have auditing turned on you wont be able to find out
-
rman cold backup and restore to create a copy database. It should be schema freeze but somehow someone still using DDL on those tables.
