SUM() Function in SQL
The SUM() function returns the total sum of a numeric column. 

  

SELECT SUM(column_name) FROM table_name

Now, we are using SQL SERVER. So, first of all we create table tblProduct and insert some products as shown in belwo. 

  

CREATE TABLE tblProduct
(
ProductId int primary key,ProductName varchar(100),Quantity int, Price int,SupplierId int
)

----------Insert some record----------

INSERT INTO tblProduct VALUES(1001,'Product1',10,2000,1)
INSERT INTO tblProduct VALUES(1002,'Product2',20,9000,2)
INSERT INTO tblProduct VALUES(1003,'Product3',12,1200,2)
INSERT INTO tblProduct VALUES(1004,'Product4',9,200,3)
INSERT INTO tblProduct VALUES(1005,'Product5',25,1000,4)
INSERT INTO tblProduct VALUES(1006,'Product6',30,300,4)
INSERT INTO tblProduct VALUES(1007,'Product7',5,2000,1)
INSERT INTO tblProduct VALUES(1008,'Product8',18,4000,5)
INSERT INTO tblProduct VALUES(1009,'Product9',10,5000,6)
