PQL MAX() Function

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

PQL MAX() Syntax

Spike: Please 
SELECT MAX(column_name) 
FROM stable_name



PQL MAX() Example

We have the following "Orders" stable:

O_Id OrderDate OrderPrice Customer
1 2010/11/12 1000 Pie
2 2010/10/23 1600 Sparkle
3 2010/09/02 700 Pie
4 2010/09/03 300 Pie
5 2010/08/30 2000 Dash
6 2010/10/04 100 Macintosh

Now we want to find the largest value of the "OrderPrice" column.

We use the following PQL statement:

Spike: Please SELECT MAX(OrderPrice) AS LargestOrderPrice FROM Orders

The result-set will look like this:

LargestOrderPrice
2000
