Hello,
I am new here and in ORACLE pl/sql.
The array dosn't passing to the body of the function.
If Ireplace the:
x InStrTab := InStrTab(v_object_name); -- Get the objects name from the select.
TO
x InStrTab := InStrTab('TBL1','TB1'); -- TBL1, TB1 are tables in my DB

The function work well.

The Function:

CREATE OR REPLACE TYPE InStrTab IS TABLE OF VARCHAR2(4000 BYTE);
/
CREATE OR REPLACE TYPE gett_arr1 AS OBJECT (
      v_OBJECT_ID     NUMBER
);
/
CREATE OR REPLACE TYPE gett_arr_TBL AS TABLE OF gett_arr1;
/

CREATE OR REPLACE FUNCTION fn_gett_arr(
      v_type IN VARCHAR2,
      v_schema_name IN VARCHAR2,
      v_object_name IN VARCHAR2
)
RETURN gett_arr_TBL AS v_ret  gett_arr_TBL;
      v_stam  VARCHAR2(250);
      v_int PLS_INTEGER;
      x InStrTab := InStrTab(v_object_name);
BEGIN
      dbms_output.put_line('The Objects var :'||v_object_name);
      SELECT
            CAST(
            multiset(
                  SELECT OBJECT_ID FROM ALL_OBJECTS WHERE OBJECT_NAME IN(SELECT TO_CHAR(column_value) FROM TABLE(CAST(x AS InStrTab)))
                  AND OWNER LIKE ''||v_schema_name||''      
            ) AS gett_arr_TBL) INTO v_ret FROM dual;
      RETURN v_ret;
      
END;
/
sho err

SELECT * FROM TABLE(fn_gett_arr('UP','SYS','''TBL1'',''TB1'''));

you are passing in '''TBL1'',''TB1''' to the function, which is a single string

when you do x InStrTab := InStrTab(v_object_name); this is still being treated as a single string, and you x table is created with a single row with value : 'TBL1','TB1' and not as two rows with values TBL1 and TB1

you could just pass it is as an array
CREATE OR REPLACE FUNCTION fn_gett_arr
   (v_type IN VARCHAR2, v_schema_name IN VARCHAR2, v_object_name IN InStrTab)
  RETURN gett_arr_TBL 
AS 
  v_ret  gett_arr_TBL;
  v_stam  VARCHAR2(250);
  v_int PLS_INTEGER;
BEGIN
  SELECT CAST( multiset( 
    SELECT OBJECT_ID FROM ALL_OBJECTS 
    WHERE OBJECT_NAME IN ( 
      SELECT TO_CHAR(column_value) FROM TABLE(CAST(v_object_name AS InStrTab)))
    AND OWNER LIKE ''||v_schema_name||'') AS gett_arr_TBL) INTO v_ret FROM dual;
  RETURN v_ret;
END;
/
 
SELECT * FROM TABLE(fn_gett_arr('UP','SYS',InStrTab('TBL1','TB1')));
