How to get current year,month,day in sql server?

In GETDATE() function will return current date and time from the SQL Server.

To get current year, I combine YEAR with GETDATE = YEAR(GETDATE());

select  YEAR(GETDATE())AS current_year;
select datepart(yyyy,getdate())AS current_year;
select datepart(MM,getdate()) AS current_month;
select datepart(dd,getdate()) AS current_day;

OUTPUT:

2016 //current year

2016 //current year
2 //current Month
18 //current day
