Syntax error MySQL query to group by column and display the sum of similar values in another column

MySQL query to group by column and display the sum of similar values in another column



For this, use GROUP BY HAVING clause.

Let us first create a table −

mysql> create table DemoTable782 (
   Name varchar(100),
   Score int
);
Query OK, 0 rows affected (1.18 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable782 values('John',156);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable782 values('Carol',250);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable782 values('Bob',140);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable782 values('John',126);
Query OK, 1 row affected (0.29 sec)
mysql> insert into DemoTable782 values('John',140);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable782 values('Bob',280);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable782 values('Bob',250);
Query OK, 1 row affected (0.41 sec)
mysql> insert into DemoTable782 values('Carol',189);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable782 values('Carol',299);
Query OK, 1 row affected (0.21 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable782;

This will produce the following output -

+-------+-------+
| Name  | Score |
+-------+-------+
| John  | 156   |
| Carol | 250   |
| Bob   | 140   |
| John  | 126   |
| John  | 140   |
| Bob   | 280   |
| Bob   | 250   |
| Carol | 189   |
| Carol | 299   |
+-------+-------+
9 rows in set (0.00 sec)

Following is the query to group by column and display the sum of similar values −

mysql> select Name,SUM(Score) AS Total
   from DemoTable782
   group by Name
   HAVING Total > 500;

This will produce the following output -

+-------+-------+
| Name  | Total |
+-------+-------+
| Carol | 738   |
| Bob   | 670   |
+-------+-------+
2 rows in set (0.00 sec)
