SUM() Function

The SUM function returns the total number of a numeric column (total amount).

SQL SUM() Syntax

SELECT SUM(column_name) FROM table_name

SQL SUM() Example

We have the following "Orders" table:

O_Id OrderDate OrderPrice Customer
1 2008/12/29 1000 Bush
2 2008/11/23 1600 Carter
3 2008/10/05 700 Bush
4 2008/09/28 300 Bush
5 2008/08/06 2000 Adams
6 2008/07/21 100 Carter

Now, we want to find the total number of the "OrderPrice" field.

We use the following SQL statement:

SELECT SUM(OrderPrice) AS OrderTotal FROM Orders

The result set is similar to this:

OrderTotal
5700
