Calling table function from procedure (pl sql) - function

Question

I am having big trouble calling a function that returns a table from my procedure. I believe there is something wrong with my declaration so its not compiling. Here is my code.. the developer underlines with red the SELECT "D_ID" and from table "(IREL_FN (X))"; . And here is my code.
CREATE OR replace PROCEDURE Irrelevant_skata (x NUMBER)
AS
d_id T_ID_TABLE;
BEGIN
DECLARE
TYPE yo_table
IS
TABLE OF YO_TABLE;
YO_TABLE "(IREL_FN (X))"%TYPE;
id NUMBER;
BEGIN
SELECT "D_ID"
INTO yo_table
FROM TABLE "(IREL_FN (X))";
EXCEPTION
WHEN no_data_found THEN
dbms_output.Put_line('NO DATA FOUND');
END;
END irrelevant_skata;
And the function
CREATE OR replace FUNCTION Irel_fn (x IN NUMBER)
RETURN T_ID_TABLE
AS
id T_ID_TABLE;
BEGIN
BEGIN
SELECT Cast(MULTISET(SELECT "id"
FROM "somethingcopy"
WHERE "kati" IN (SELECT "auto"
FROM "ekeino"
WHERE "id" = x)) AS T_ID_TABLE)
INTO id
FROM dual;
RETURN id;
EXCEPTION
WHEN no_data_found THEN
dbms_output.Put_line('null');
END;
END irel_fn;

Answer 1

It's hard to answer without knowing what you're trying to do.
YO_TABLE "(IREL_FN (X))"%TYPE;
This doesn't make any sense. You can't declare a variable to be %type of a function. Looking up at YO_TABLE declaration, you write
DECLARE
TYPE yo_table
IS
TABLE OF YO_TABLE;
Huh? table declaration is table of same variable you're declaring?
And this:
SELECT "D_ID"
INTO yo_table
FROM TABLE "(IREL_FN (X))";
You don't need quotes when casting table, and the x in IREL_FN (X) is a formal parameter, you need to replace it with the actual value what you need to pass

Answer 2

create or replace
PROCEDURE IRRELEVANT_SKATA (INSID IN NUMBER) AS ID T_ID_TABLE ;
BEGIN
DECLARE
YO_TABLE T_ID_TABLE;
BEGIN
select ID
into YO_TABLE
from table(IREL_FN(INSID));
EXCEPTION
WHEN NO_DATA_FOUND THEN dbms_output.put_line('NO DATA FOUND');
END;
END IRRELEVANT_TWEET;
<-----------------------------FUNCTION---------------------------------->
create or replace
FUNCTION IREL_FN ( D_ID IN NUMBER ) RETURN T_ID_TABLE AS
ID T_ID_TABLE;
BEGIN
BEGIN
SELECT CAST(
MULTISET(
SELECT "Id"
FROM "SOMETHINGCOPY"
WHERE "KATI" = (SELECT "EKEINO" FROM "AUTO" WHERE "Id"=D_ID)
INTO ID
FROM DUAL;
return ID;
EXCEPTION
WHEN NO_DATA_FOUND THEN dbms_output.put_line('null');
END;
END IREL_FN;
I hope I helped :)

Answer 3

I am answering to your question marked as duplicate (the problem with exact fetch).
I rewrote your code in the following way, hope it helps. I makes the Irel_fn to be a pipelined function, however you can still write Cast multiset if you like , however you need to use type constructor as well.
create table auto(id number)
this table is instead of your source "AUTO" (so I could compile it).
create or replace type t_id as object (id number);
/
Create or replace type t_id_table is table of t_id;
/
create or replace FUNCTION Irel_fn (x IN NUMBER) RETURN T_ID_TABLE PIPELINED
as
BEGIN
for rec in (select id from auto where id=x)
loop
Pipe row (t_id(rec.id));
end loop;
return;
end;
/
create or replace procedure Irrelevant_skata (insid in NUMBER) is
bob t_id_table;
BEGIN
select t_id(id) bulk collect into bob from table(irel_fn(insid));
END;
