MySQL query to multiply values of two rows and add the result
For this, use aggregate function SUM(). Within this method, multiply the row values. Let us first create a table −
mysql> create table DemoTable(
ProductQuantity int,
ProductPrice int
);
Query OK, 0 rows affected (0.48 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(10,9);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values(6,20);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values(7,100);
Query OK, 1 row affected (0.08 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-----------------+--------------+
| ProductQuantity | ProductPrice |
+-----------------+--------------+
| 10 | 9 |
| 6 | 20 |
| 7 | 100 |
+-----------------+--------------+
3 rows in set (0.00 sec)
Following is the query to multiply values of two rows and add the result −
mysql> select SUM(ProductQuantity*ProductPrice) AS Total_Value from DemoTable;
This will produce the following output −
+-------------+
| Total_Value |
+-------------+
| 910 |
+-------------+
1 row in set (0.00 sec)
