SQL query for extracting year from a date

Question

I am trying to create a query that gets only the year from selected dates. I.e. select ASOFDATE from PSASOFDATE; returns 11/15/2012, but I want only

Answer 1

How about this one?

SELECT TO_CHAR(ASOFDATE, 'YYYY') FROM PSASOFDATE

Answer 2

This worked for me:

SELECT EXTRACT(YEAR FROM ASOFDATE) FROM PSASOFDATE;

Answer 3

SELECT date_column_name FROM table_name WHERE EXTRACT(YEAR FROM date_column_name) = 2020

Answer 4

Edit: due to post-tag 'oracle', the first two queries become irrelevant, leaving 3rd query for oracle.

For MySQL:

SELECT YEAR(ASOFDATE) FROM PASOFDATE

Editted: In anycase if your date is a String, let's convert it into a proper date format. And select the year out of it.

SELECT YEAR(STR_TO_DATE(ASOFDATE, '%d-%b-%Y')) FROM PSASOFDATE

Since you are trying Toad, can you check the following code:

For Oracle:

SELECT EXTRACT (TO_DATE(YEAR, 'MM/DD/YY') FROM ASOFDATE) FROM PSASOFDATE;

Reference:

Answer 5

just pass the columnName as parameter of YEAR

SELECT YEAR(ASOFDATE) from PSASOFDATE;

another is to use DATE_FORMAT

SELECT DATE_FORMAT(ASOFDATE, '%Y') from PSASOFDATE;

UPDATE 1

I bet the value is varchar with the format MM/dd/YYYY, it that's the case,

SELECT YEAR(STR_TO_DATE('11/15/2012', '%m/%d/%Y'));

LAST RESORT if all the queries fail

use SUBSTRING

SELECT SUBSTRING('11/15/2012', 7, 4)
