David, SysDate is a function and can be referenced in any SQL statement. So you could do the following if you want seconds between the two, or leave off some or all of the trailing multiplicands to get fractional minutes, hours or days.
Select ( SysDate - Next_Date ) * 24 * 60 * 60 >From User_Refresh ; You need to do a little reading in the Oracle SQL Reference under Datatypes to find out details of the Date datatype and Date arithmetic.
