Not understanding your query, what is your subtotal??

SubTotal= Price after discount and quantity(that selected by customer)

Total =sum of all SubTotals

And still price * qty doesn't answer you question???

It is simple
C#
SalePrice();
var unitPrice =  long.Parse(lblPrice.Text);
var qty = int.Parse(txbQty.Text);

var subTotal = unitPrice * qty;

By salePrice() you have the discounted price that applies to all products. So subtotal is the sum of all totals.

Hi,

Why can't you implement the same in SQL Server,try below query to achieve the same in SQL server side.

SQL
select sum(col) as SubTotal
from tablename
Group by Quantity, Price
