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)
