Vertica Correlate Subquery with NOT IN clause - vertica

Question

I have put all the DDL and query in sqlfiddel link below
http://sqlfiddle.com/#!9/89c76/2
Same thing here
create table players(name varchar(32),playerid int);
insert into players values("a",1);
insert into players values("b",2);
insert into players values("c",3);
insert into players values("d",4);
insert into players values("e",5);
insert into players values("f",6);
select * from players;
create table matches(playerid int,game varchar(32));
insert into matches values(1,"game1");
insert into matches values(2,"game1");
insert into matches values(3,"game1");
insert into matches values(1,"game2");
insert into matches values(2,"game2");
insert into matches values(3,"game2");
insert into matches values(4,"game3");
insert into matches values(5,"game2");
select * from matches;
commit;
and the query is
select p.playerid,m.game
from players p, (select distinct game from matches) m
where p.playerid not in (select playerid from matches where game=m.game)
I get the following error
[Vertica][VJDBC](2795) ERROR: Correlated subquery with NOT IN is not supported [SQL State=0A000, DB Errorcode=2795]
samething is mentioned in vertica doc.
How can I, rewrite this query?
I need results as
Result:
------------------------
game1 | 4,5,6
------------------------
game2 | 4,6
------------------------
game3 | 1,2,3,5,6
------------------------
....
I had posted this issue in the vertica forum and found the solution through Kim_nicely

select p.playerid, m.game from players p cross join (select distinct game from matches) m
minus
select * from matches
order by 1, 2;

Based on the query, the logic is to get all players that did not play in game1 and players that did not play any game. You can also get the players not in game1 by doing below. Notice the difference on the left join on m.game='game1'.
I can only do one game becuase the new requirements need stored procedure in vertica. I don't have experience on it but sql.
select 'game1', group_concat(t.playerid) playerid
from (
select p.playerid
from players p
left join matches m
on p.playerid = m.playerid and m.game='game1'
where m.playerid is null
UNION
select p.playerid
from players p
left join matches m
on p.playerid = m.playerid
where m.playerid is null) t
