SQL MAX() Function

MAX() Function

The MAX function returns the maximum value in a column. NULL values are not included in the calculation.

SQL MAX() Syntax

SELECT MAX(column_name) FROM table_name

Note:MIN and MAX can also be used for text columns to obtain the highest or lowest value in alphabetical order.

SQL MAX() 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 maximum value in the "OrderPrice" column.

We use the following SQL statement:

SELECT MAX(OrderPrice) AS LargestOrderPrice FROM Orders

The result set is similar to this:

LargestOrderPrice
2000
