python error PLS-00306: wrong number or types of arguments in
Hello
I am using the zxJDBC package with jython (similar to python), and I
am having "python error PLS-00306: wrong number or types of arguments"
error when using the "callproc()" method to execute a stored
procedure.
The Oracle stored procedure takes a single OUT varchar2 parameter. My
code is as follows:
p = [None]
c.callproc('pkg1_returns', p);
...
What I am doing corresponds to the examples..but I can seem to know
why it is not working. Help.

Thanks, your assistance will be greatly appreciated on the right way
forward. See the Stored Procedure Below -very simple:
create or replace package c2_pkg
as
procedure openc;
procedure closec;
procedure RS22(v out varchar);
end;
/
create or replace package body c2_pkg
as
v_first_time boolean := TRUE;
v_cursor number;
cursor srvr_cur
is
select distinct b.mid from SVR a,VAR b where a.mid = b.mid;
procedure openc
as
begin
if not srvr_cur%ISOPEN
then
open srvr_cur;
end if;
end openc;
procedure closec
as
begin
close srvr_cur;
end closec;
procedure RS22(v out varchar2)
as
-- Server varchar2(64);
begin
Server := NULL;
fetch srvr_cur into Server;
v := Server;
end RS22;
end;

Re: python error PLS-00306: wrong number or types of arguments in
The actual jython/python call is:
p = [None]
c.callproc('c2_pkg.RS22', p);
I used a placeholder initially; now that you have the SQL code, there
it is. It essentially invokes the stored procedure, and it should
return the OUT variable p, with some value. It doesn't have to be a
cursor fetch; even a minor text assignment.

It's taking an OUT parameter.. I'm just following the examples as
documented by zxJDBC. How can I fix it?

The same error. The sample were found on the following site --I copied
exactly what is written there:

So I will most likely use it. Basically, just call a function, outside a package. It resolves this entire dilemma. Implementing similar program in Perl DBI, works without any problem. Python/Jython seem quite difficult to work with Store Procedures, in my opinion. Thanks a lot. -- http://mail.python.org/mailman/listinfo/python-list

I just left it outside a package, and it works. -- http://mail.python.org/mailman/listinfo/python-list
