Calculates a date value by adding years to (or subtracting years from) a specified date value.
Syntax
$addyears(date,number)
Parameters
date | a date, or an expression that evaluates to a DATE data type |
number | a number, or an expression that evaluates to a number |
Return Value
Number, representing a DATE value.
Comments
Use $addyears to perform arithmetic with date values. The $addyears function calculates a date value by adding a number representing years to a date value. If number is negative, the effect is to subtract the years from the date.
The + (add) and – (subtract) operators can be used to achieve the same results.
If date or the result of the $addyears expression is an invalid date (e.g., 19930231), it is adjusted to produce a valid date (e.g., 19930228).
Example
If $Date has the value 19981225, then
$addyears($date,5)
Evaluates to 20041225.
$addyears($date,-5)
Evaluates to 19931225.
$addyears(19980229,1)
Evaluates to 19990228.
