Hi Folks,

I've been reading the docs over and again, searching exhaustively for
examples on the internet to help me here and I'm ready to give up.

I have a query using windows function:

SELECT
    last_value ( typechange )      OVER w,
    pindex,
    lid,
    last_value ( modified )   OVER w,
    last_value ( created )    OVER w,
    last_value ( modifiedby ) OVER w,
    last_value ( createby )   OVER w,
    last_value ( cost ) FILTER ( WHERE cost IS NOT NULL ) OVER w,
    last_value ( sell ) FILTER ( WHERE sell IS NOT NULL ) OVER w
FROM ps._delta_ext
WHERE pindex = Ppindex AND
    ( Plid IS NULL OR lid = Plid ) AND
    ( Ptimestamp IS NULL OR modified <= Ptimestamp )
GROUP BY lid, pindex
WINDOW w AS ( PARITION BY lid, pindex ORDER BY created );
Complains about syntax error in the WINDOW cause (last line) on [PARTITION]
BY:
/* messages
ERROR:  syntax error at or near "BY"
LINE 16:  WINDOW w AS ( PARITION BY locationid, partindex ORDER BY cr...
                                 ^
SQL state: 42601
Character: 2724
*/

Maybe my error is clear to someone else, could really use helping hand,
thanks.
