I figured I'd ask this too. I know how to remove duplicate rows from a table, but this example used an analytical function. I'm new to these and do not get a huge chance to use them, so I'm always forgetting how they work.

Please see this:

select * from customer
where rowid in
 (select rowid from

     (partition by customer_id order by customer_id ) dup
    from customer)
  where dup > 1);

Ok, that did show me the duplicates, but what if a duplicate was made up of more than 1 column? Can I still use an analytical function?

This is where I might learn about these things......

Thank you. Received on Fri Jul 25 2008 - 23:33:28 CDT
