How can I calculate the total value of products from my MySQL product table?
Let us first create a table −
mysql> create table DemoTable ( ProductId int NOT NULL AUTO_INCREMENT PRIMARY KEY, ProductQuantity int, ProductPrice int ); Query OK, 0 rows affected (0.19 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(ProductQuantity,ProductPrice) values(10,100); Query OK, 1 row affected (0.06 sec) mysql> insert into DemoTable(ProductQuantity,ProductPrice) values(5,11); Query OK, 1 row affected (0.04 sec) mysql> insert into DemoTable(ProductQuantity,ProductPrice) values(3,140); Query OK, 1 row affected (0.05 sec) mysql> insert into DemoTable(ProductQuantity,ProductPrice) values(2,450); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-----------+-----------------+--------------+ | ProductId | ProductQuantity | ProductPrice | +-----------+-----------------+--------------+ | 1 | 10 | 100 | | 2 | 5 | 11 | | 3 | 3 | 140 | | 4 | 2 | 450 | +-----------+-----------------+--------------+ 4 rows in set (0.00 sec)
Following is the query to calculate total value of products −
mysql> select sum(ProductQuantity*ProductPrice) as Total_of_Products from DemoTable;
This will produce the following output −
+-------------------+ | Total_of_Products | +-------------------+ | 2375 | +-------------------+ 1 row in set (0.00 sec)
