<div>I have script, using DBI, to alter a table to add/modify column in an Oracle table. I have set autocommit off and didn't invoke commit(). In fact, I invoked rollback(). So I was surprised to see that I was able to add a column to the table!</div> <div> </div> <div>Should this be so? What else could be causing this behavior?</div> <div> </div> <div>Thanks</div> <div> </div><p>
