Question

I’m trying to find out how to show the total value in a table (item*quantity) of all the items in one line. The code below shows the total of every single item on one line each, not the total value of all of them. How can this be done?

I guess I should use a subquery, but not how to design it.

Thanks in advance

SELECT CONVERT(Decimal(8,0),ROUND((quantity*price),2)) AS Total
FROM Item

EDIT: By mistage I included ITEMNAME, that shall NOT be a part of the result!

The table is designed as follows:

ITEMNAME   QUANTITY   PRICE
Table      20         100
Chair      30         50
and so on

The result is as follows:

ITEMNAME   TOTAL
Table      2000
Chair      1500

I want it this way:

TOTAL
3500

Answer 1

SELECT SUM (quantity*price) AS Total
FROM Item
