Hi ,

I am using below logic to verify whether the given value is present or not in the array. In that I also wanted to fetch the index of the value. Is this possible with the below approach? Please let me know if any other approach to fetch.

set serveroutput on
declare
    tabtype_exist_del_grp_org   FND_TABLE_OF_NUMBER := FND_TABLE_OF_NUMBER ();
    v_row_num       number;
    v_del_grp_exist varchar2(30);
    v_del_exist varchar2(30);
begin
    tabtype_exist_del_grp_org.extend;
    tabtype_exist_del_grp_org (1) := 184;
    tabtype_exist_del_grp_org.extend;
    tabtype_exist_del_grp_org (2) := 185;
    tabtype_exist_del_grp_org.extend;
    tabtype_exist_del_grp_org (3) := 243;
    
    BEGIN
        SELECT  ROWNUM, COLUMN_VALUE, 'Y'
        INTO    v_row_num, v_del_grp_exist, v_del_exist
        FROM    TABLE(tabtype_exist_del_grp_org)
        WHERE   COLUMN_VALUE = 243;
                                
    EXCEPTION
    WHEN NO_DATA_FOUND
    THEN
        v_del_exist := 'N'; 
                                                         
    WHEN OTHERS
    THEN
        v_del_exist := 'N';
    END;
    
    dbms_output.put_line ('v_del_grp_exist : '||v_del_grp_exist);
    dbms_output.put_line ('v_row_num : '||v_row_num);
    dbms_output.put_line ('v_del_exist : '||v_del_exist);

end;

You can & should do this without using SQL within your PL/SQL (faster, no context switches):

...
  v_del_grp_exist := 243;
  v_indx := tabtype_exist_del_grp_org.first;
  while v_indx is not null loop
    if tabtype_exist_del_grp_org(v_indx) = v_del_grp_exist then
      dbms_output.put_line('value found!');
      exit;
    end if;
    v_indx := tabtype_exist_del_grp_org.next(v_indx);
  end loop;
...
