Calculating years of experience using YEAR( )

Question

Hi all,
I am trying to calculate the years of experience for every employee in a company. Ideally, I hope the system will update the years of experiece every year without hardcoding.
For example, instead of:
Select 2010 - emp.start_year
from emp
I want to use:
Select YEAR(GETDATE()) - emp.start_year
from emp
However, apex gave me an error saying "YEAR" is not a valid identifier.
What's wrong and how do I fix that?
Thank you very much for the help!

Answer 1

So the Year( ) and GETDATE( ) functions don't work in APEX?No they don't work in Oracle, as they are Microsoft SQL Server functions.
Why did you "want" to use them? See the Oracle SQL Reference:

The EXTRACT function is useful in extracting date components for use in calculations, eliminating the need for nesting multiple conversion functions:
select extract(year from sysdate) - extract(year from hiredate)
from emp;
