David,

Select (DateTime1 - DateTime2) * 24 * 60 * 60
>From Dual

;

Oracle date arithmetic results are in fractional days, so the above gets you the number of seconds between two Date datatype arguments. Of course you can go ahead and multiply 24*60*60 to get Seconds/Day, but I prefer to leave it that way so it's more obvious what my intent is.

Is it possible to calculate seconds using SQL?

For example, I'd like to subtract these two time to get difference in seconds:

10:20:32 - 10:25:29

Thanks,
David
