Hello,
If column fu is of data type DATE, you could use
SELECT EXTRACT(YEAR FROM fu) FROM mydate;
and if it is varchar, you convert it to date using to_date()
SELECT EXTRACT(YEAR FROM to_date(fu, <your pattern>)) FROM mydate;
Regards.

I think you'd just want something like:
SELECT EXTRACT(YEAR FROM fu) FROM mydate;
DATE '2000-01-01' is a syntax for providing a date literal, not treating
an expression as a date.
