PLS-00306 explicit vs implicit cursors

I have a package similar to this simplified example:


create or replace package test is
PROCEDURE recon_2;
PROCEDURE recon_3;
PROCEDURE recon_4;
end test;


create or replace package body test is

PROCEDURE recon_1
(fiid iforce_riadmin.transactions.fi_src_sys_cd%TYPE)
IS
BEGIN
DBMS_OUTPUT.PUT_LINE ('COMPLETED: '||fiid);
END;


PROCEDURE recon_2 IS
BEGIN
recon_1 ('wach');
END;


PROCEDURE recon_3 IS
CURSOR c_fiid IS
SELECT distinct 'wach'
FROM iforce_riadmin.transactions;
BEGIN
FOR fiid in c_fiid LOOP
recon_1 (fiid); --<<-- PLS-00306 error
END LOOP;
END;


PROCEDURE recon_4 IS
CURSOR c_fiid IS
SELECT distinct 'wach'
FROM iforce_riadmin.transactions;
fiid iforce_riadmin.transactions.fi_src_sys_cd%TYPE;
BEGIN
open c_fiid;
loop
fetch c_fiid into fiid;
exit when c_fiid%notfound;
recon_1 (fiid);
end loop;

END;

end test;



PROCEDURES recon_1, 2, and 4 are compiling without a problem.

How come recon_3 does not compile and give PLS-00306 wrong number or types of arguments in call to 'RECON_1' ??

PROCEDURE recon_3 IS
CURSOR c_fiid IS
SELECT distinct 'wach'
FROM iforce_riadmin.transactions;
BEGIN
FOR fiid in c_fiid LOOP
recon_1 (fiid); --<<-- PLS-00306 error
END LOOP;
END;

Try this:

Code:

---

PROCEDURE recon_3 IS
  CURSOR c_fiid IS
  SELECT distinct 'wach' as colname
    FROM iforce_riadmin.transactions;
BEGIN
    FOR fiid in c_fiid LOOP
          recon_1 (fiid.colname);
    END LOOP;
END;
