MySQL random rows sorted by a specific column name?
Let us first create a table −
mysql> create table DemoTable1339 -> ( -> Name varchar(30), -> Score int -> ); Query OK, 0 rows affected (0.76 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1339 values('Chris',56);
Query OK, 1 row affected (0.36 sec)
mysql> insert into DemoTable1339 values('Bob',46);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1339 values('Adam',78);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable1339 values('John',90);
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable1339 values('Carol',98);
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1339;
This will produce the following output −
+-------+-------+ | Name | Score | +-------+-------+ | Chris | 56 | | Bob | 46 | | Adam | 78 | | John | 90 | | Carol | 98 | +-------+-------+ 5 rows in set (0.00 sec)
Following is the query to sort random rows by NAME column −
mysql> select * from (select *from DemoTable1339 order by rand() limit 4) tbl order by Name;
This will produce the following output −
+-------+-------+ | Name | Score | +-------+-------+ | Adam | 78 | | Bob | 46 | | Carol | 98 | | Chris | 56 | +-------+-------+ 4 rows in set (0.05 sec)
