MySQL extract year from date format?

To extract year from date format, you can use in-built function YEAR() from MySQL. The query is as follows −

mysql> SELECT YEAR(curdate()) as OnlyYearFromCurrentDate;

The following is the output −

+-------------------------+
| OnlyYearFromCurrentDate |
+-------------------------+
| 2018                    |
+-------------------------+
1 row in set (0.00 sec)

Or you can do in the following way −

mysql> SELECT YEAR(date(now())) as OnlyYearFromCurrentDate;

The following is the output −

+-------------------------+
| OnlyYearFromCurrentDate |
+-------------------------+
| 2018                    |
+-------------------------+
1 row in set (0.00 sec)

With that, you can even achieve this when column is varchar. Let us first create a table −

mysql> create table ExtractYearDemo
   −> (
   −> YourDueTime varchar(200)
   −> );
Query OK, 0 rows affected (1.15 sec)

Inserting records into the table with the help of insert command. The query is as follows −

mysql> insert into ExtractYearDemo values('27-10-2011');
Query OK, 1 row affected (0.16 sec)

mysql> insert into ExtractYearDemo values('28-11-2012');
Query OK, 1 row affected (0.15 sec)

mysql> insert into ExtractYearDemo values('29-12-2018');
Query OK, 1 row affected (0.14 sec)

mysql> insert into ExtractYearDemo values('01-01-2019');
Query OK, 1 row affected (0.15 sec)

Displaying all records from the table with the help of SELECT statement. The query is as follows −

mysql> select *from ExtractYearDemo;

The following is the output −

+-------------+
| YourDueTime |
+-------------+
| 27-10-2011  |
| 28-11-2012  |
| 29-12-2018  |
| 01-01-2019  |
+-------------+
4 rows in set (0.00 sec)

The following is the query to extract year from table column when column is varchar type −

mysql> select YEAR(STR_TO_DATE(yourDueTime, "%d-%m-%Y")) As OnlyYearFromDate from ExtractYearDemo;

The following is the output displaying year −

+------------------+
| OnlyYearFromDate |
+------------------+
|             2011 |
|             2012 |
|             2018 |
|             2019 |
+------------------+
4 rows in set (0.00 sec)
