Javascript, ODBC, and Oracle functions returning cursors

Dear Experts,

I'm attempting to marry a system to an Oracle 817 datbase.
Oracle is my specialty, the back end mainly, so I don't
know much about java or javascript.

The system uses javascript to make ODBC calls to the db.

The particular system I'm working with, will not work
with an Oracle stored procedure I'm told. However, it
will work with a stored function.

I made a simple function in Oracle to return a single
integer. It works in sqlplus, but not via javascript.
-----------------------

Create or replace function fnc_rtn_integer
Return integer
As
Ln_temp integer := 0;
Begin
Select count(*)
Into ln_temp
From dual;
Return LN_TEMP;

End;
-----------------------
Sqlplus:

declare
ln_temp integer := -1;
begin
ln_temp := fnc_rtn_integer ;
dbms_output.put _line (ln_temp);
end;

1
-----------------------
javascript:
ESC.tb.pop_addr =1;{call fnc_rtn_integer }

Netscape Privledge Manager exception

davox.host.Host Conn:get ESC.tb.pop_addr Host -2 ? [State: S1000]
[Oracle][ODBC][Ora]ORA-24334: no descriptor for this position

-----------------------
2)

The developers need to get a number of rows back.
I've made an Oracle function, that will return a
number of rows.

----------------------

CREATE OR REPLACE FUNCTION fnc_rtn_emp_inf o
RETURN types.ref_curso r
AS
emp_cursor types.ref_curso r;

BEGIN

OPEN emp_cursor FOR
SELECT empno,
ENAME,
JOB
From EMP;

RETURN emp_cursor;

END;
CREATE OR REPLACE function fnc_dept_rpt
Return types.DeptCurTy p
AS

dept_cv types.DeptCurTy p ;

BEGIN
OPEN dept_cv FOR
SELECT DEPTNO,
DNAME,
LOC
FROM DEPT;

Return dept_cv;
END;

----------------

ESC.tb.pop_addr =1;{call FNC_DEPT_RPT()}

FNC_DEPT_RPT

-----------------------

A few questions.

1)
I'm sure that this could be just a syntax issue.
Any ideas? Please send the exact sytax that it should be.
2)
Does anyone have experience getting a number of rows back
with an Oracle cursor? Is this possible? Am I doing it
in the right way?
Thanks a lot!

Why in the world are you spamming every language newgroup under the SUN?
comp.databases. oracle.server,c omp.lang.javasc ript,comp.lang. java.api,comp.l
ang.basic.visua l.database,comp .lang.perl.misc

Either your ODBC or JS code is FUBAR. PL/SQL does know know or care
about the language of the code which calls it. PL/SQL is too dumb to know
or care about the calling language.

For somebody who specialises in Oracle, but does not know about getting rows
from a cursor, your come across as a prize idiot.

Please dont bother us in comp.lang.perl. misc.

Javascrit comes in 2 flavours: client-side (that appears within the
webpage). This can only manipulate items on the webpage. It can not
open files or databases.

Server-side: also known as JScript. This allows you to do all the file
/ database manipulation stuff. Check with your web people as to what
web server they are running. If IIS then ASP/JScript, ASP/VBScript or
PHP will do. If any other server then check what server-side language
they support.

Sample listed below:
-----------------------------------------------
<%@LANGUAGE="JA VASCRIPT" CODEPAGE="1252" %>
<!--#include file="../Connections/ELVASS.asp" -->
<%
//--- get data from the webpage form
var tpid = Request.QuerySt ring("tpid");
var qid = Request.QuerySt ring("qid");
if( isNaN(tpid) || isNaN(qid) ) Response.Redire ct("../menu.asp");

//--- global variables
var fname="", fExt="", TPName="", QName="", Ver="", AppDt="",
mainID=0;
var fso, f2;
var src="", dst = "", wrd="";

function WriteFormData( mainid, cid, type, fname )
{
//--- use this syntax for insert, update and delete queries
var w = Server.CreateOb ject('ADODB.Com mand');
w.ActiveConnect ion = MM_ELVASS_STRIN G;
w.CommandText = "INSERT INTO forms (fk_mainID, fk_cid,
type,filename) Values (" + mainid + "," + cid + ",\"" + type + "\",\""
+ fname + "\")";
w.Execute();
w.ActiveConnect ion.Close();
}

//--- get general information
//--- use this syntax for select queries
var db = Server.CreateOb ject("ADODB.Rec ordset");
db.ActiveConnec tion = MM_ELVASS_STRIN G;
db.Source = "SELECT main.id form main WHERE fk_TrainingPack age=" +
tpid + " AND fkQualID=" + qid;
db.CursorType = 0;
db.CursorLocati on = 2;
db.LockType = 1;
db.Open();
while( !db.EOF )
{
//--- do something
db.moveNext();
}
db.Close();
