Re: Order rows

I suppose you can if you don't care about wasted disk space, I know everyone says "disk is cheap" but that's only until you explain to your manager that you need a 100GB disk for a 10GB (real used space) database because you are forcing order by storing each row in one block and never reusing space freed up by deleted rows :)

Rachel:

If you want to FORCE the order you can do couple of things like having a big PCTFREE (to make sure that no rows are migrated because of the updates) and small PCTUSED so that the blocks are never reused. In this case you will get the
rows in the inserted order.

ANother alternative is your method (additional column SYSDATE)
