MySQL query to sum up values of rows and sort the result?

MySQLMySQLi Database

For this, you can use GROUP BY along with ORDER BY clause. Let us first create a table −

mysql> create table DemoTable1499
   -> (
   -> StudentName varchar(20),
   -> StudentMarks int
   -> );
Query OK, 0 rows affected (0.46 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1499 values('Chris',56);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1499 values('David',78);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1499 values('Bob',98);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable1499 values('Chris',45);
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1499 values('David',98);
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1499 values('Bob',58);
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

Mysql> select * from DemoTable1499;

This will produce the following output −

+-------------+--------------+
| StudentName | StudentMarks |
+-------------+--------------+
| Chris       |           56 |
| David       |           78 |
| Bob         |           98 |
| Chris       |           45 |
| David       |           98 |
| Bob         |           58 |
+-------------+--------------+
6 rows in set (0.00 sec)

Following is the query to sum up values of rows and sort the result −

mysql> select StudentName,sum(StudentMarks) as TotalSum from DemoTable1499
   -> group by StudentName
   -> order by TotalSum desc;

This will produce the following output −

+-------------+----------+
| StudentName | TotalSum |
+-------------+----------+
| David       |      176 |
| Bob         |      156 |
| Chris       |      101 |
+-------------+----------+
3 rows in set (0.00 sec)
