Selecting random entry from MySQL Database?
Let us first create a table −
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, ClientName varchar(100), ClientAge int ); Query OK, 0 rows affected (0.92 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(ClientName,ClientAge) values('Robert',45);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable(ClientName,ClientAge) values('Mike',55);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(ClientName,ClientAge) values('Bob',42);
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable(ClientName,ClientAge) values('Sam',47);
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+------------+-----------+ | Id | ClientName | ClientAge | +----+------------+-----------+ | 1 | Robert | 45 | | 2 | Mike | 55 | | 3 | Bob | 42 | | 4 | Sam | 47 | +----+------------+-----------+ 4 rows in set (0.00 sec)
Following is the query to select a random entry from MySQL database −
mysql> select *from DemoTable order by rand() limit 1;
This will produce the following output −
+----+------------+-----------+ | Id | ClientName | ClientAge | +----+------------+-----------+ | 3 | Bob | 42 | +----+------------+-----------+ 1 row in set (0.00 sec)
