How to select a random record from a MySQL database?
For this, you can use ORDER BY RAND LIMIT. Let us first create a table −
mysql> create table DemoTable1581
-> (
-> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
-> StudentName varchar(20)
-> );
Query OK, 0 rows affected (1.34 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1581(StudentName) values('Chris');
Query OK, 1 row affected (0.41 sec)
mysql> insert into DemoTable1581(StudentName) values('Bob');
Query OK, 1 row affected (1.58 sec)
mysql> insert into DemoTable1581(StudentName) values('Sam');
Query OK, 1 row affected (2.11 sec)
mysql> insert into DemoTable1581(StudentName) values('Mike');
Query OK, 1 row affected (0.55 sec)
mysql> insert into DemoTable1581(StudentName) values('Carol');
Query OK, 1 row affected (0.16 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1581;
This will produce the following output −
+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
| 1 | Chris |
| 2 | Bob |
| 3 | Sam |
| 4 | Mike |
| 5 | Carol |
+-----------+-------------+
5 rows in set (0.00 sec)
Here is the query to select a random record from a MySQL database −
mysql> select * from DemoTable1581 order by rand() limit 1;
This will produce the following output −
+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
| 4 | Mike |
+-----------+-------------+
1 row in set (0.07 sec)
