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.

If the procedure takes a varchar2 parameter, why are you passing [None]?

It might help if you posted the method signature of the Oracle stored
procedure you're trying to call.

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;

I don't see a procedure named "pkg1_returns", which is the prodecure
called by your code. Where is this procedure?

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.

That procedure is defined as taking one parameter, but you're passing
an empty parameter list. Why?

I'm new to jython...

I suspect the example you're looking at was for a procedure which has no
arguments, so in that case it would make sense to pass an empty parameter
list.

I haven't worked with OUT parameters so I don't know if this will work,
but try it and see what happens:

my_string = ""
p = [my_string]
c.callproc('c2_pkg.RS22', p);
print p

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