List Function

Converting Sybase to SQL Server !

On the Sql Server's database I did :

-- test list function with cursor
alter proc proc_list(@key varchar(255), @retlistvalues varchar(8000) output)
as
declare @incrcurs2 cursor
declare @value varchar(255)
declare @listvalues varchar(8000)
set @incrcurs2 = cursor scroll dynamic
for
select t.title_Id from publishers p, titles t where p.pub_id = t.pub_idand p.pub_id = @key
order by t.pub_id
open @incrcurs2
fetch next from @incrcurs2 into @value
select @listvalues = convert(varchar(255),@value)
WHILE @@FETCH_STATUS = 0
begin
select @listvalues = @listvalues + ',' + convert(varchar(255),@value)
fetch next from @incrcurs2 into @value
end
CLOSE @incrcurs2
DEALLOCATE @incrcurs2
select @retlistvalues = @listvalues
go
declare @listvalues varchar(8000)
execute proc_list '1389',@listvalues output
print @listvalues

With Sybase, easily :
Select t.pub_id, list(t.title_Id) from publishers p, titles t where p.pub_id = t.pub_id
And I 've got all the titles in a comma-separated string by publisher !!!!

So, with SQL Server, I suppose that if I want the result by publisher, I must imbricate two cursors !!!

Perhaps I dream
Or can somebody see a better solution ????
