Problem in executing procedure in 8.1.7

Question

Hi,
I have created the below mentioned procedure. It got compiled successfully. But when i try to execute it is giving error
"PLS-00306: wrong number or types of arguments in call to 'P1' ORA-06550: line2, column3: PL/SQL".
But if i hardcode the projectId to any number value & execute the procedure, it is getting executed successfully.
CREATE OR REPLACE PROCEDURE p1 (projectid NUMBER)
IS
CURSOR c1
IS
SELECT sl_no, col1, col2, col3
FROM (SELECT ROWNUM sl_no, LEVEL col2,
col3, col4, col5
FROM (SELECT col2, col3, col4, col5
FROM tabl1 tab_level
WHERE tab_level.project_id = projectid
AND tab_level.active_in = 'Y'
AND tab_level.delete_in = 'N') tab1
CONNECT BY PRIOR tab1.col3 = tab1.col4
START WITH (col3, col5) IN (SELECT col3, MAX (col5)
FROM tabl1 tab_parent
WHERE tab_parent.project_id =
projectid
AND NVL (tab_parent.col4, 0) =
0
AND tab_parent.active_in = 'Y'
AND tab_parent.delete_in = 'N'
GROUP BY col3)) table1,
table2,
tabl33
WHERE table1.col2 = table2.col2 AND tabl1.col1 = table3.col1;
BEGIN
FOR i IN c1
LOOP
DBMS_OUTPUT.put_line ('Success');
END LOOP;
END;
Basically here i am selecting some columns from third level SELECT. If i change it to second level SELECT it works fine without hardcoding. Can you help me in finding the problem in the code.
Thanks for the help,
Sunil.

Sunil,
Hierarchical query ie CONNECT BY PRIOR clause doesnt work on views or inline views in Oracle 8.1.7. So your procedure is failing. Upto 8.1.7, the hierarchical queries work only on tables.
If you try the same in 9i, it will work.
Hope this helps
