# SQL SUM() Function

## The SUM() Function

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

### 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 | 2008/11/12 | 1000 | Hansen
2 | 2008/10/23 | 1600 | Nilsen
3 | 2008/09/02 | 700 | Hansen
4 | 2008/09/03 | 300 | Hansen
5 | 2008/08/30 | 2000 | Jensen
6 | 2008/10/04 | 100 | Nilsen

Now we want to find the sum of all "OrderPrice" fields".

We use the following SQL statement:

    SELECT SUM(OrderPrice) AS OrderTotal FROM Orders

The result-set will look like this:

OrderTotal
5700
