Reshuffle the values in a table with MySQL

To reshuffle the values in a table, use MySQL RAND().

Let us first create a table −

mysql> create table DemoTable792 ( Name varchar(100), Subject varchar(100) ); Query OK, 0 rows affected (0.66 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable792 values('Chris','MySQL'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable792 values('David','MySQL'); Query OK, 1 row affected (0.22 sec) mysql> insert into DemoTable792 values('Robert','MongoDB'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable792 values('Carol','MongoDB'); Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable792;

This will produce the following output -

+--------+---------+ | Name | Subject | +--------+---------+ | Chris | MySQL | | David | MySQL | | Robert | MongoDB | | Carol | MongoDB | +--------+---------+ 4 rows in set (0.00 sec)

Following is the query to reshuffle the values in a table −

mysql> select *from DemoTable792 order by rand();

This will produce the following output -

+--------+---------+ | Name | Subject | +--------+---------+ | Chris | MySQL | | Robert | MongoDB | | David | MySQL | | Carol | MongoDB | +--------+---------+ 4 rows in set (0.00 sec)
