database Search possible on Oracle?

This was asked in a meeting of following people and the answers are amazing...

An Analyst replied
 - I need a month time to prepare analysis whether it is possible or the way possible

Technical architect replied
 -It is not impossible but involves lots of work.

Team Lead interrupted
 - Google it , you should be able to find it

One in the team suggested
- It will cause performance issues

Developer maintained a silence until everyone calmed down and said..
- Lets make use of data dictionaries
- Find out Varchar fields and construct a query
- Lets list objects that has the data searched
- We will then narrow down our search
- It is not time-consuming job yet not a quick one

Analyst quickly replied - We know that, but it is not right to do as it will cause unnecessary issues
Team Lead                     - Were you not supposed to complete the other assignment? You concentrate on that!!!
Technical Architect        - Do you know the system issues?
Developer                       - ??!!!?????!!!!!!!!

How to remove duplicate rows without using DISTINCT or ROWID or GROUP BY methods in Oracle?

Make use of SET operators and CTAS (Create Table AS) method.. Example: Create table tmp_tb1 as Select * from table1 intersect Select * from table1; truncate table table1; insert into table1 select * from tmp_tb1; -- This will now have removed all duplicates in the table... commit; *** You can use UNION operator in place of INTERSECT
