Selecting Random Result from MySQL?
You need to use rand() function to select random result from MySQL.
The syntax is as follows
select *from yourTableName order by rand() limit 1;
To understand the above syntax, let us create a table. The query to create a table is as follows
mysql> create table selectRandomRecord -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(20) -> ); Query OK, 0 rows affected (0.53 sec)
Insert some records in the table using insert command.
The query is as follows
mysql> insert into selectRandomRecord(StudentName) values('John');
Query OK, 1 row affected (0.17 sec)
mysql> insert into selectRandomRecord(StudentName) values('Carol');
Query OK, 1 row affected (0.14 sec)
mysql> insert into selectRandomRecord(StudentName) values('Bob');
Query OK, 1 row affected (0.12 sec)
mysql> insert into selectRandomRecord(StudentName) values('Sam');
Query OK, 1 row affected (0.15 sec)
mysql> insert into selectRandomRecord(StudentName) values('Mike');
Query OK, 1 row affected (0.16 sec)
mysql> insert into selectRandomRecord(StudentName) values('Robert');
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement.
The query is as follows
mysql> select *from selectRandomRecord;
The following is the output
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 1 | John | | 2 | Carol | | 3 | Bob | | 4 | Sam | | 5 | Mike | | 6 | Robert | +-----------+-------------+ 6 rows in set (0.00 sec)
The following is the query to select random result from MySQL.
mysql> select *from selectRandomRecord order by rand() limit 1;
The following is the output
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 3 | Bob | +-----------+-------------+ 1 row in set (0.00 sec)
Now execute the same query again to get another random value
mysql> select *from selectRandomRecord order by rand() limit 1;
The following is the output
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 5 | Mike | +-----------+-------------+ 1 row in set (0.00 sec)
