Output parameters or how to return more than one value

My RMI server retrieves a list of Strings from the database. I need to return a status code int and an array of Strings to the RMI client. Does anybody have any ideas on how to do this. The only way I have come up with is to return an array of Strings using the first array position as the status code. But this is very ugly. There doesn't seem to be any way to have output parameters. I can use "output parameters" with code that lies in the same app by using wrapper classes or arrays but this does not really apply to a client and server running on different machines. Any ideas?

Well, my general reaction is that you don't need a status code. (You can instead throw an exception if the status is anything but "OK".)
However, on the assumption that you really DO need the status, then some alternatives are
o Return an object that has a status code and an array as member variables.
o In the call, pass in an object that the server can fill in with the array of strings. have the function return the status code.

How to return more than one value from a function

hello everybody,
Can anyone tell me how to return more than a single value from a function, the problem is i have 4 points,
2 points form one line ,another 2 points form 2nd line ,each point is 3 dimensional(x,y,z coorinates) so i will pass these values to func(x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4), i will find the point of intersecton of two lines and i will get it as x,y,z , now how to return these 3 coordinates,usually the function returns only one value, please help me to solve it out.
Thanks.

I think the easiest way or trick here is (easiest isn't always the best as we know, but atleast this one will work) to create simple data array. and pass that. Create an array with:
<code>
class justArray {
int x=0
int y=0;
int z= 0;
...somewhere
justArray[] points= new justArray[4];
points[0].x= ..
points[0].y= ..
points[0].z= ..
points[1].x= ..
return points[]

Posting your Oracle version is immensely helpful when asking questions (different version = different answers / functionality available).
select * from v$version;Also, using tags will preserve the formatting of your code.
You should likely read (a lot) about [http://www.stanford.edu/dept/itss/docs/oracle/10g/appdev.101/b10807/05_colls.htm]
Basically, you would need to create a PL/SQL record and reference that, OR you could create a SQL type.
If you're looking for a 'simple' way to return many single values (no arrays) then your best bet would be a procedure with multiple OUT parameters.

Can Function Return more than One Values ??

Hi Experts,
I would like to ask you Can Function Return more than one values. I Used Function with Out and In out parameter and its working Fine..
1. what is harm using Out and In out parameter in function
2. if we can use Out and In out parameter in Function so what is deffernce between procedure and Function.
3. Is there any Other Way Though which we can return more the One values in Function.
Please advice me...
Thanks

Yes/No.
You can return multiple value from function. But, in PL/SQL and not in a SQL.

Can a method return more than one value?

I was studying for my biology exam and I got bored and I started thinking and then I wandered if a method can return more than one value...?
For example, if I want a method to return a row a column, I make a method that returns an int. But what if I want to return two ints? Or what If I want to return an integer and a string? Is it possible or do I have make two methods, each returning one thing?
What I always did until now is is I want for example to return a few integers, I would store them in a String and then when I return the string, I parse the numbers out using stringtokenizer... but it doesn't look like the best way... and it's pretty annoying...

I'm weak on terminology, hence I don't even know what
AFAIK means...As Far As I Know
This doesn't really make sense for me. It's more
efficient to make a whole class just for two
integers, than having two methods? Efficiency is not the point. The flow is.
If you have two methods, the caller must be aware of both of them. The other way it's up to the callee.
Just because the
two integers are related to each other? Doesn't
making a class require more memory usage than just
making two one-line methods?The memory usage is not wholly irrelevant, but there are ways to handle that (caching, inlining, etc.).
It's a bit hard to counter your point for me, but if you had done a lot of GUI painting stuff, you'd see all those Points, Dimensions, Rectangles, you name it, are quite invaluable.

Can oracle function return more than one value

Hi All
please answer can oracle function return more than one value
need one schenario
regards

Can any function, irrespective of the language, return multiple values?
OF COURSE NOT!!
So why do you think Oracle will now suddenly do it differently than all other languages? Never mind that it is impossible for a function (a unit/module of code) returning a memory address, to return multiple memory addresses. The machine code that does that, has not been yet been designed/implemented.
I am continually amazed that this question is asked. It is about something so fundamental in almost every single 3rd and 4th generation language... something that is taught right at the start... the definition of what a procedure and what a function is.
Sorry, but I simply cannot pull punches on this subject and smooth it over. There is something fundamentally wrong with your training as a programmer if you have to ask such a question about a function.
And whatever programming skills you build on such a foundation, will be seriously lacking.
I kindly suggest that you get back to the very basics of programming - and review and revisit until you fully understand it. There are no shortcuts in becomming a good programmer.

How to return more than one record through OUT parameter in procedure

Hi,
I want to create a procedure which accepts one input and returns more than one record as output.
example:
Input = DeptNo
Output= Empno,ename,sal,comm,job
Scenario:
There can be more than one employee in department we pass as the IN parameter. OUT parameter has to return all the records of the corresponding employee details in that department.
Thanks in advance for your help
Regards,
K.Vijay

-- I think you can try something like this using ref cursor:
-- create a package for the type ref cursor and execute
CREATE OR REPLACE PACKAGE PACK_REFCURSOR_FOR_TABLES AS
     TYPE DATA_TableRows IS REF CURSOR;
END;
-- after executing the package above, create your procedure:
CREATE OR REPLACE PROCEDURE GET_EMP (
     IN_nDeptNo IN number,
     OUT_Emp OUT PACK_REFCURSOR_FOR_TABLES.DATA_TableRows)
IS
BEGIN
-- leave query open (implicit) as this will return data
     OPEN OUT_Emp FOR
     SELECT *
     FROM tblEmp
     WHERE DeptNo = IN_nDeptNo;
END;
--execute the procedure and you're done

How to send more than one value to the Jump target report variable screen.

Hi,
I have two reports with Plant variable on their input variable screens. Say this Plant can take two values X and Y. The first report is executed with Plant value X and displays data. When a jump is made to report two, Plant value X is retrievd into report two's plant varible value. Now how to send value Y also to Report two when jump is made. I think we can do it with a customer exit? Any help is appreciated
Thanks
Bhanu

Hi Bhanu,
I guess u have created a Variable with Sinlge value ,So Create a Variable which has Multiple Sinlge Values or Interval so that u can have more than one value and if u hvae more than value u will get data for those values and when u do a jump then u can see the data in the JUMP query for both the Values of Input.

LOV Return more than one value to differenent items on page

New to express. I need to returm more than one value from list of LOV. For example: LOV => select a, b, c from testtable
I would then like to
a to populate item1 => with submit
b to populate item2 => hidden
c to pupulate item3 => hidden
as items on my page
when a user chooses a (with submit) in item1 b and c would populate also, b and c are hidden to the user. Any advice?

How to return more than one string?

Hi,below is my code:
@WebMethod(operationName = "CheckBooking")
public String CheckBooking(@WebParam(name = "ID")
String ID) {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:Flight");
// Statement stmt = con.createStatement();
String b="Select Destination, Date from Flight_Booking WHERE BookingID=?";
PreparedStatement ps=con.prepareStatement(b);
ps.setString(1,ID);
ResultSet a = ps.executeQuery();
//Print the data to the console
while(a.next()){
return a.getString(1);
catch( Exception e ) {
e.printStackTrace();
return "a";
Actually, I would like to select Destination and Date from the database, but if I set the return result as string, then only Destination will be return,how can I modify it so that both of the Destination and Date also will be return?As I know, .Net has a return type called Dataset, in Java what should I write?
Actually,I am writing this web services to consume it on a table from .Net,so what is the most suitable to code it so that more than one string can be return?

Create either a list or an array and assign your values to it and return it.

How to pass more than one value in RfcRequest ?

Hi Experts,
I have a FModule (addition) which is exposed as an Enterprise Service. This FM takes two values as input(VAL1 and VAL2) and gives the result (RESULT). I have done the configuration to connect to the backend system via SAP Widget Foundation. When i tried to test in URL :
http://localhost:7531/SapMiddleTier/REST/ewcs/service/rfct/form , i gave the input for the RFC Query Parameters as : <VAL1>10</VAL1><VAL2>20</VAL2> , but i get an error "Expecting Expression" .
Am i giving the input in the wrong format ?
I wrote another FM which doesnt take any input but returns some text as output and when i queried it via the above URL, i get the correct result. I again tested with changing the Fmodule that accepts one input and returns one output and i find that it returning perfectly. But when i try with more than one input i get the below error.
Could some one please help ?
See the error :
<?xml version="1.0" encoding="UTF-8"?>

Hi John,
Thank you for your reply.
Am trying to test my FM(using http://localhost:7531/SapMiddleTier/REST/ewcs/service/rfct/form) as mentioned in this link:
http://nvpal168.pal.sap.corp:1080/widgetgallery/staticPage.seam?pageId=staticPage9
I had downloaded the SAP Widget Foundation and its running.
Using the link : http://localhost:7531/SapMiddleTier/REST/ewcs/service/rfct/form we can test exposed function modules . If you are using SAP Widget Foundation, then the above link will open up a form
where in the user gives RFC parameters.
I gave it as <VAL1>10</VAL1><VAL2>20</VAL2> and click on Query RFC = > i get the above mentioned error. If this works, then i can call my function module via Adobe flex using HTTP Service with the service url as "http://localhost:7531/SapMiddleTier/REST/ewcs/service/rfct/form".
Best Regards,
Sam.

you can create your on array type and then pass that as the parameter. I use the suffix of ttyp to represent a table type. The name of the column when using the table() syntax is columnvalue.
I altered my session to set the default date format to match your format. you could have used the to_date function to set the values for the arr type.
Hope this helps.
create type msw_ttyp as table of date
create or replace
procedure msw_test(p_arr     in msw_ttyp) as
v     integer;
begin
select count(*)
   into v
   from table(p_arr);
dbms_output.put_line('count: '||v);
for rec in (select column_value
               from table(p_arr))
loop
dbms_output.put_line(rec.column_value);
end loop;
end msw_test;
alter session set nls_date_format = 'MM/DD/YYYY';
set serveroutput on size 1000000
exec msw_test(msw_ttyp('01/17/2010', '01/27/2010','05/22/2010'));
begin
msw_test(msw_ttyp(to_date('01/17/2010', 'MM/DD/YYYY'),
                   to_date('01/27/2010', 'MM/DD/YYYY'),
                   to_date('05/22/2010', 'MM/DD/YYYY')));
end;
