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)
