How to do write a sql to retrieve data matching values in a varray?
I have the following:
declare
    v_ct          NATURAL := 0;
    type t_cur is  REF CURSOR;
    v_cursor t_cur;
    TYPE t_array IS VARRAY(100) OF NUMBER;
    l_codes t_array := t_array();
begin
    select count(*)
      into v_ct
      from table1
     where ind_cd IS NULL;
    IF v_ct = 0 THEN
        l_codes(1) := 1;
    END IF;
    select count(*)
      into v_ct
      from table2
     where cd IS NULL;
    IF v_ct = 0 THEN
        l_codes(2) := 2;
    END IF;  
   OPEN v_cursor for
      select * from error_table where error_cd in (SELECT * FROM TABLE(CAST(l_codes AS t_array)) );
end;

This may not answer your question, but what about a pure SQL solution?
NOTE THIS IS UNTESTED:
SELECT *
FROM     ERROR_TABLE
WHERE     ERROR_CD IN
          SELECT      1
          FROM      table1
          HAVING      COUNT(*) > 0
          UNION ALL
          SELECT      2
          FROM      table2
          HAVING      COUNT(*) > 0
