MySQL randomly select 2 values from column values?
To randomly select, use ORDER BY RAND(). To select only 2 values, use LIMIT 2 in MySQL. Let us first create a table −
mysql> create table DemoTable1815
(
Question text
);
Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1815 values('What is your name?');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1815 values('What is your college name?');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1815 values('What is your nick name?');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1815 values('What is your enemy name?');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1815;
This will produce the following output −
+----------------------------+
| Question |
+----------------------------+
| What is your name? |
| What is your college name? |
| What is your nick name? |
| What is your enemy name? |
+----------------------------+
4 rows in set (0.00 sec)
Here is the query to randomly select only 2 records −
mysql> select * from DemoTable1815 order by rand() limit 2;
This will produce the following output −
+----------------------------+
| Question |
+----------------------------+
| What is your college name? |
| What is your enemy name? |
+----------------------------+
2 rows in set (0.00 sec)
