Select random row that exists in a MySQL table?


To select random value, use rand(). Here, we are selecting only a single random value, therefore, LIMIT 1 is used. Following is the syntax −

select *from yourTableName order by rand() limit 1;

Let us first create a table −

mysql> create table DemoTable735 (Amount int);
Query OK, 0 rows affected (0.57 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable735 values(984474734);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable735 values(489393323);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable735 values(23432333);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable735 values(8949933);
Query OK, 1 row affected (0.14 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable735;

This will produce the following output -

+-----------+
| Amount    |
+-----------+
| 984474734 |
| 489393323 |
| 23432333  |
| 8949933   |
+-----------+
4 rows in set (0.00 sec)

Following is the query to select random row in MySQL

mysql> select *from DemoTable735 order by rand() limit 1;

This will produce the following output -

+-----------+
| Amount    |
+-----------+
| 489393323 |
+-----------+
1 row in set (0.00 sec)
