How can i get the total number of hours between two dates using SQL in Oracle.  For example...

 SELECT (to_date('3/28/2011 12:46','mm/dd/yyyy hh24:mi') - to_date('3/28/2011 11:59','mm/dd/yyyy hh24:mi'))   from dual  

returns..'0.0326388888888888888888888888888888888889'

i need to get that into a time which in this case would be 47 minutes.  how can I do that?

(to_date('3/28/2011 12:46','mm/dd/yyyy hh24:mi') - to_date('3/28/2011 11:59','mm/dd/yyyy hh24:mi'))  * 1440


the 1440 is number of minutes in a day

if you want the value to be in hours then multiply the result by 24 instead of 1440

that will yield .7833333  hours

If you want the breakdown of hours, minutes and seconds not just one:  There are several links out there on how to do this.

For example, seconds to hours,minutesmseconds:

If you can go with the TIMESTAMP data type, the math is a little easier.

Both methods are covered in:
