How do I update the "Hire Date" date value to the current year or the next
year if the "Hire Date" is less then 365 days old to be shown as an
evaluation due date?
DateAdd() is your friend here.
Dateadd("yyyy",1,hiredate) will turn oct. 21st, 2009 to oct. 21st 2010
That is what you update your field to. You can put a negative # in
DateAdd, (and it subtracts) in order to determine whether a date of more
or less then 265days form another date.
IIf([Hiredate]>Dateadd("d",-365,[DueDate]),
Dateadd("yyyy",1,[hiredate]), [[hiredate]])
would add a year to anything less then a year different.
These are just ideas, how you implement it is up to you, but DateAdd()
is the key.
