Can I get Age using BirthDate column in a MySQL query?

To get Age using BirthDate column in a MySQL query, you can use datediff(). Let us first create a table:

mysql> create table DemoTable (    Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,    DateOfBirth date ); Query OK, 0 rows affected (1.46 sec)

Following is the query to insert some records in the table using insert command:

mysql> insert into DemoTable(DateOfBirth) values('2010-01-21'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(DateOfBirth) values('1993-04-02'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable(DateOfBirth) values('1999-12-01'); Query OK, 1 row affected (1.53 sec) mysql> insert into DemoTable(DateOfBirth) values('1998-11-16'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable(DateOfBirth) values('2004-03-19'); Query OK, 1 row affected (0.11 sec)

Following is the query to display records from the table using select command:

mysql> select *from DemoTable;

This will produce the following output:

+----+-------------+ | Id | DateOfBirth | +----+-------------+ |  1 | 2010-01-21  | |  2 | 1993-04-02  | |  3 | 1999-12-01  | |  4 | 1998-11-16  | |  5 | 2004-03-19  | +----+-------------+ 5 rows in set (0.00 sec)

Let us now get Age using birthdate column with DATEDIFF() method:

mysql> select cast(DATEDIFF(curdate(),DateOfBirth) / 365.25 AS UNSIGNED) AS AGE from DemoTable;

This will produce the following output:

+------+ | AGE  | +------+ |    9 | | 26 | | 19 | | 20 | | 15 | +------+ 5 rows in set (0.00 sec)

Let us now write a query to get the DOB and ID where Age is between 20 and 26:

mysql> SELECT *FROM DemoTable WHERE YEAR(CURDATE())-YEAR(DateOfBirth) BETWEEN 20 AND 26;

This will produce the following output:

+----+-------------+ | Id | DateOfBirth | +----+-------------+ | 2 | 1993-04-02 | | 3 | 1999-12-01 | | 4 | 1998-11-16 | +----+-------------+ 3 rows in set (0.00 sec)
