Re: Adding Numeric Field to a Date

[Quoted] Whart is the definietion of enddate? If it is date, the math should work. If it is number, then the error you are seeing is the result.

You may add or subtract a number to / from a date resulting in a date. You may subract one date from another resulting in a number. Oracle will casting from one datatype to another. Your examples with literals show this.
