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)
