SQL MAX() Function

The MAX() function returns the largest value of the selected column.

SQL MAX() Syntax

SELECT MAX(column_name) FROM table_name

SQL MAX() Example

We have the following "Orders" table:

Id	OrderDate	OrderPrice	Customer
1	2008/11/12	1000	Navis
2	2008/10/23	1600	Nilsen
3	2008/09/02	700	Navis
4	2008/09/03	300	Navis
5	2008/08/30	2000	Jensen
6	2008/10/04	100	Nilsen

Now we want to find the largest value of the "OrderPrice" column.
We use the following SQL statement:

SELECT MAX(OrderPrice) AS LargestOrderPrice FROM Orders

The result-set will look like this:

LargestOrderPrice
