How do I get the current year using SQL on Oracle?

Question

I need to add the current year as a variable in an SQL statement, how can I retrieve the current year using SQL?

i.e.

  BETWEEN 
    TO_DATE('01/01/**currentYear** 00:00:00', 'DD/MM/YYYY HH24:MI:SS')
    AND
    TO_DATE('31/12/**currentYear** 23:59:59', 'DD/MM/YYYY HH24:MI:SS')

Answer 1

Using to_char:

select to_char(sysdate, 'YYYY') from dual;

In your example you can use something like:

BETWEEN trunc(sysdate, 'YEAR') 
    AND add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60;

The comparison values are exactly what you request:

select trunc(sysdate, 'YEAR') begin_year
     , add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60 last_second_year
from dual;

BEGIN_YEAR  LAST_SECOND_YEAR
----------- ----------------
01/01/2009  31/12/2009

Answer 2

Another option is:

SELECT *
  FROM TABLE
 WHERE EXTRACT( YEAR FROM date_field) = EXTRACT(YEAR FROM sysdate) 

Answer 3

Use extract(datetime) function it's so easy, simple.

It returns year, month, day, minute, second

Example:

select extract(year from sysdate) from dual;

Answer 4

Yet another option would be:

SELECT * FROM mytable
 WHERE TRUNC(mydate, 'YEAR') = TRUNC(SYSDATE, 'YEAR');

Answer 5

Since we are doing this one to death - you don't have to specify a year:

select * from demo
where  somedate between to_date('01/01 00:00:00', 'DD/MM HH24:MI:SS')
                and     to_date('31/12 23:59:59', 'DD/MM HH24:MI:SS');

However the accepted answer by FerranB makes more sense if you want to specify all date values that fall within the current year.

Answer 6

To display the current system date in oracle-sql

   select sysdate from dual;
