DB2 SQL window functions

I recently purchased the SQL cookbook from oreilly, and one of the
topics is something called "window functions". According to the book
this is one of a whole group of analytical functions that was added in
the SQL - 99 standard. I tried to run the very simple query:

 

SELECT 

SUIT, 

WEIGHT, 

count(*) over() 

FROM 

cpayne.window

 

and got the response:

 

Token ( was not valid. Valid tokens: , FROM INTO.      

 

Does anyone know about these window functions? Have they been
implemented in DB2/400?
