How to add a select system date statement in the where clause

Need help. I try to add a select clause in where clause in my query so that it can select the data which is same as the device system date .

my code that work:
(EXTRACT(YEAR FROM W.BrwDate) = '2021')

I try to add select sysdate from dual; so no need to write the specific year and query can be use for every year . But if i combine the code it no work

WHERE (EXTRACT(YEAR FROM RegYear = (select sysdate extract (year from dual))))

So is that any method can solve my mistake?

>Solution :

Should be

where extract (year from regyear) = extract (year from sysdate)
