Help with query Condition

Question

--Sample create/insert :
create table xxdummy(
id integer,
name varchar2(40),
description varchar2(100)
insert into xxdummy values (1,'L', 'Simple L press');
insert into xxdummy values (2,'XL', 'XL with no film');
insert into xxdummy values (2,'web', 'XL with no film');
insert into xxdummy values (3,'XL', 'XL with Film');
insert into xxdummy values (3,'Film', 'XL with Film');
insert into xxdummy values (3,'print', 'XL with Film');
insert into xxdummy values (4,'S', 'servo with film');
insert into xxdummy values (4,'Film','servo with film' );
insert into xxdummy values (5,'S','only servo' );
insert into xxdummy values (6,'L', 'Simple L press');
insert into xxdummy values (7,'XL', 'XL with no film');
insert into xxdummy values (8,'XL', 'XL with Film');
insert into xxdummy values (8,'Film', 'XL with Film');
insert into xxdummy values (8,'guide', 'XL with Film');
--drop table xxdummy;
select * from xxdummy;
select id, description, decode(name, 'L', 'L Only', 'XL', 'Got XLs here', 'dont know' ) type
from xxdummy
where name in ('L','XL' )
In above query for column type, I want to display 'L Only', 'XL With Film', 'XL Without Film'
How can I do this ?
Thanks

Answer 1

I should have explained more, but my mind is so fried making up sample replica of the data as its scattered over so many tables in the original query taht I couldnt put it properly:
another try :
column Description is just for my reference , So please ignore that for now.
I have to form a condition only using colums name and id.
select * from xxdummy :
id=2 and 7 , has name=XL but doesnt have 'Film' so I want to mark this row as 'XL with no film'
id=3 and 8 , has name=XL and also has name = Film, So label for this should be - XL With Film
id=4 , has name=S and also Film, --All the ids that have name=S, no matter if it has film with same Id should be excluded.
id=5, exclude it
id=1 and 6 have name = L , Lable them 'L Only' .
So I should basically have 6 rows returned in my sample data :
select id, description, name, decode(name, 'L', 'L Only', 'XL', 'Got XLs here' ,'dont know') type
from xxdummy
where name in ('L','XL')
how do I distinguish within id, that has name=XL : which one has film and which one doesnt
did it sound better ?
