Get Comma separated result from SQL Query

Question

Hey Everyone
I have a requirement where i need to get comma separated result of names because there is one to many relationship i.e for every protocol there are mutiple people associated to it , and i created PL/SQL function for that and everything was fine and when it is in production multiple number of cursors were opened because of the logic and leading to RAC fail over and for that we were manually clearing the cursors every weekend and i am looking to create a Materialized view for this logic but i was unable to code the logic using Connect by clause
Result is like and i want comma separated names for every protocol

from
S_PT_POS_HST_LS T544105 /* S_PT_POS_HST_LS_Protocol_Team */ ,
S_CONTACT T565804 /* S_CONTACT_Protocol_Team */,
S_CL_PTCL_LS T541903 /* S_CL_PTCL_LS_Protocol */
where ( T541903.ROW_ID = T544105.CL_PTCL_ID and
T544105.POSTN_ID = T565804.PR_HELD_POSTN_ID and
T544105.ROLE_CD = 'Lead Project Manager' AND
T541903.ROW_ID = v_PTCL_ID and
T541903.PAR_PTCL_ID is null and T544105.END_DT is null );
BEGIN
l_row_num := 0;
l_role := '';
l_role_list := '';
v_PTCL_ID := PTCL_ID;
OPEN C_GSCR;
if C_GSCR%isopen THEN
LOOP
FETCH C_GSCR INTO l_role;
exit when C_GSCR%notfound;
IF l_role_list IS NULL THEN
l_role_list:=l_role;
ELSE
l_role_list:=l_role_list||', '||l_role;
END IF;
END LOOP;
CLOSE C_GSCR;
end if;

Thanks for the Info .. My database in 10g R 2 i started using COLLECT Function
select T541903.PTCL_NUM ,
CAST(COLLECT(T565804.FST_NAME||' '||T565804.LAST_NAME) AS varchar2_ntt) , 7) AS LPM_NAME
from
S_PT_POS_HST_LS T544105 /* S_PT_POS_HST_LS_Protocol_Team */ ,

The result i like ...Do you mean "The result *is* like ..."?
Or do you mean "The result I [would] like [is] ..."?
The code above has unblanaced parentheses. If you are getting anything other than an error message, then I don't believe you are really running what you posted.
Whenever you have a problem, post a complete test script that people can use to recreate the problem and test their ideas.
Please do that. Post CREATE TABLE and INSERT statements to crate the sample data, the code you used to create the carachr2_ntt type and the function, and your best attempt at a query (formatted). Simplify as much as possible. For example, do you really need 3 tables to illustrate the problem? For purposes of asking a question on this forum, can't you pretend you have just one table, with 2 columns?
I suspect the problem has to do with the user-defined type and function, which you didn't post. I can't even see how you called the function in your query. Without the information I mentioned above, there's not much I can do to help you.
