Understanding Date Arithmetic

The transformation language provides built-in date functions so you can perform arithmetic on datetime values as follows:

ADD_TO_DATE.
Add or subtract a specific portion of a date.

DATE_DIFF.
Subtract two dates.

SET_DATE_PART.
Change one part of a date.

You cannot use numeric arithmetic operators (such as + or -) to add or subtract dates.

The transformation language recognizes leap years and accepts dates between Jan. 1, 0001 00:00:00.000000000 A.D. and Dec. 31, 9999 23:59:59.999999999 A.D.

The transformation language uses the transformation Date/Time datatype to specify date values. You can only use the date functions on datetime values.
