Calculate age based on date of birth in MySQL?
Calculate Age based on date of birth with the help of DATE_FORMAT() method in MySQL. Firstly, get the current date time with the help of now() method and you can place your date of birth in DATE_FORMAT().
The syntax is as follows −
SELECT DATE_FORMAT(FROM_DAYS(DATEDIFF(now(),'yourDateofbirth')), '%Y')+0 AS anyVariableName;
Apply the above syntax to calculate age from yourDateofbirth. In the above syntax, replace yourDateofbirth with your date of birth. The query is as follows −
SELECT DATE_FORMAT(FROM_DAYS(DATEDIFF(now(),'2010-11-25')), '%Y')+0 AS Age;
The following is the output −
+------+ | Age | +------+ | 8 | +------+ 1 row in set (0.00 sec)
Let us now see this in an example. Firstly, create a table −
mysql> create table AgeCalculationFromDatetime -> ( -> YourDateofBirth datetime -> ); Query OK, 0 rows affected (0.52 sec)
Inserting date of birth into table. The query is as follows −
mysql> insert into AgeCalculationFromDatetime values('1995-11-25');
Query OK, 1 row affected (0.13 sec)Displaying all records with the help of select statement. The query is as follows −
mysql> select *from AgeCalculationFromDatetime;
The following is the output −
+---------------------+ | YourDateofBirth | +---------------------+ | 1995-11-25 00:00:00 | +---------------------+ 1 row in set (0.00 sec)
The query to calculate age is as follows −
mysql> SELECT DATE_FORMAT(FROM_DAYS(DATEDIFF(now(),YourDateofBirth)), '%Y')+0 AS Age from AgeCalculationFromDatetime;
Here is the output −
+------+ | Age | +------+ | 23 | +------+ 1 row in set (0.00 sec)`
