How to fetch random rows in MySQL with comma separated values?
To fetch random rows in MySQL, use ORDER BY RAND(). Let us first create a table −
mysql> create table DemoTable1835 ( ListOfIds varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1835 values('10,20,30');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1835 values('70,80,90');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1835 values('45,67,89');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1835 values('98,96,49');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1835;
This will produce the following output −
+-----------+ | ListOfIds | +-----------+ | 10,20,30 | | 70,80,90 | | 45,67,89 | | 98,96,49 | +-----------+ 4 rows in set (0.00 sec)
Here is the query to fetch random rows in MySQL
mysql> select * from DemoTable1835 where ListOfIds NOT IN(10,20,70) order by rand() limit 2;
This will produce the following output −
+-----------+ | ListOfIds | +-----------+ | 98,96,49 | | 45,67,89 | +-----------+ 2 rows in set, 4 warnings (0.00 sec)
