How to find out when a particular table was created in Oracle?

Question

In Oracle, is there a way to find out when a particular table was created?

Similarly, is there a way to find out when a particular row was inserted/last updated?

Answer 1

You can query the data dictionary/catalog views to find out when an object was created as well as the time of last DDL involving the object (example: alter table)

select * 
  from all_objects 
 where owner = ''
   and object_name = ''

The column "CREATED" tells you when the object was created. The column "LAST_DDL_TIME" tells you when the last DDL was performed against the object.

As for when a particular row was inserted/updated, you can use audit columns like an "insert_timestamp" column or use a trigger and populate an audit table
