Count and sort rows with a single MySQL query
Let us first create a table −
mysql> create table DemoTable783 ( FirstName varchar(100) ); Query OK, 0 rows affected (0.65 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable783 values('Adam');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable783 values('Chris');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable783 values('Chris');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable783 values('Adam');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable783 values('Adam');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable783 values('Robert');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable783 values('Robert');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable783 values('Adam');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable783 values('Chris');
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −
mysql> select *from DemoTable783;
This will produce the following output -
+-----------+ | FirstName | +-----------+ | Adam | | Chris | | Chris | | Adam | | Adam | | Robert | | Robert | | Adam | | Chris | +-----------+ 9 rows in set (0.00 sec)
Following is the query to count and sort rows in MySQL −
mysql> select FirstName, count(*) from DemoTable783 group by FirstName order by count(*) desc;
This will produce the following output -
+-----------+----------+ | FirstName | count(*) | +-----------+----------+ | Adam | 4 | | Chris | 3 | | Robert | 2 | +-----------+----------+ 3 rows in set (0.00 sec)
