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

PQL last()

PQL min()
