AVG() Function in SQL:-
The AVG() function returns the average value of a numeric column. 

  

SELECT AVG(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)

SELECT AVG(Price) AS TOTAL_PRICE  FROM tblProduct
