How to display the day name on the basis of Date of Birth records in MySQL?

Use the DAYNAME() to display the day name from records with Date of Birth.

Let us first create a table −

mysql> create table DemoTable795 (
   DateOfBirth date
);
Query OK, 0 rows affected (0.61 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable795 values('1996-01-21');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable795 values('2004-11-01');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable795 values('1990-03-31');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable795 values('2010-12-03');
Query OK, 1 row affected (0.13 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable795;

This will produce the following output -

+-------------+
| DateOfBirth |
+-------------+
| 1996-01-21  |
| 2004-11-01  |
| 1990-03-31  |
| 2010-12-03  |
+-------------+
4 rows in set (0.00 sec)

Following is the query to display the day name on the basis of Date of Birth −

mysql> select dayname(DateOfBirth) from DemoTable795;

This will produce the following output -

+----------------------+
| dayname(DateOfBirth) |
+----------------------+
| Sunday               |
| Monday               |
| Saturday             |
| Friday               |
+----------------------+
