title: Oracle - Best SELECT statement for getting the difference in minutes between two DateTime columns?
body: <p>I'm attempting to fulfill a rather difficult reporting request from a client, and I need to find away to get the difference between two DateTime columns in minutes.  I've attempted to use trunc and round with various <a href="http://www.ss64.com/orasyntax/fmt.html" rel="noreferrer">formats</a> and can't seem to come up with a combination that makes sense.  Is there an elegant way to do this?  If not, is there <b>any</b> way to do this?</p>
