MySQL - SUM rows with same ID?
To sum rows with same ID, use the GROUP BY HAVING clause.
Let us create a table −
Example
mysql> create table demo84
-> (
-> id int,
-> price int
-> )
-> ;
Query OK, 0 rows affected (0.60
Insert some records into the table with the help of insert command −
Example
mysql> insert into demo84 values(1,2000);
Query OK, 1 row affected (0.08
mysql> insert into demo84 values(1,2000);
Query OK, 1 row affected (0.14
mysql> insert into demo84 values(2,1800);
Query OK, 1 row affected (0.14
mysql> insert into demo84 values(2,2200);
Query OK, 1 row affected (0.14
mysql> insert into demo84 values(3,1700);
Query OK, 1 row affected (0.12
Display records from the table using select statement −
Example
mysql> select *from demo84;
This will produce the following output −
Output
+------+-------+
| id | price |
+------+-------+
| 1 | 2000 |
| 1 | 2000 |
| 2 | 1800 |
| 2 | 2200 |
| 3 | 1700 |
+------+-------+
5 rows in set (0.00 sec)
Following is the query to sum rows with same id −
Example
mysql> select id,sum(price) as Total from demo84
-> group by id
-> having sum(demo84.price) >=2000;
This will produce the following output −
Output
+------+-------+
| id | Total |
+------+-------+
| 1 | 4000 |
| 2 | 4000 |
+------+-------+
2 rows in set (0.00 sec)
