How to return more then one value in OC4J

Hi,
do I really need to create a serializable object + interface with an reader and writer to pass more then 2 variables back to the client ?
Must this object a java bean ?
.. or does anybody know an easier way to solve this problems.
greetings
Mike

What is your client, and what are you using on the server? Are you trying to return values from a servlet to a web page, or from a servlet to a JSP, or from a EJB to a Java client?
John H. Hi John
We have some services currentliy implementet as PL/SQL stored Procedures on Oracle. They are now accessable with DCE and C-clients.
The task is now to implement the services as Web-Services with SOAP. For that we want to use the OC4J. - as an SOAP Server.
But unforunatly the only examples I found are returning only one parameter.
The Java books learned me to create a class and an interface to pass more parameter to the client. This interface should be inherit from Serializable.
The compiler is happy, the deployment is ok. But when I try to get the wsdl and stub I get something like: "must be an bean" or "have to be a reader and write property.
From my point of view this looks very complicated. I want to use SOAP and therefore all parameters should be passed with one call and the parameter should be explained in the WSDL so that they could be used independed of the programming language and plattform.
When I implement the read and write methods I will pass the parameters in one stream. When I only use Java I think this is a solution - but what is with C or other languages.
Ciao Mike

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.

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 retrieve more then one record from database

I am doing a SELECT FROM WHERE SQL statement on a database which returns more then one record. I want to retrieve certain column values from the selected records. How do I do that? If only one record is returned, I know I can do a data operation with operation set to 'Get-Retrieve Values from Record' and Record to operate on set to 'Current-Use current record'. I need to find out how to configure to data operation window in the case more then one record is returned by the preceding SQL statement. Depending on the number of records returned, I can dynamically create array variables to store the 'to be retrieved' column values, just dont know how to retrieve them.
Any help will be greatly appreciated.
Thanks
Anuj

I apologize for not being clear in explaining my problem, perhaps I should have posted an example. Anyways, I was able to figure out the solution. I was doing an 'Open SQL' statement which was selecting multiple records (rows) from a table in the dB. I was storing the number of records returned in a local variable. Then, I wanted to retrieve certain columns of all the selected rows (records). In the "Data operation", I was choosing the 'Record to operate on' as 'Current-Use Current Record'. Changing this field to 'Next-Fetch next record' fixed the problem. I then retrieved the values of those columns into a dynamically created array variable whose dimensions came from the local variable which stored the number of records returned in the SELECT SQL statement.

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 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 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.

If u are talking about session, get 2 session names and move them to different sessions or if both txn are dependant on each other, move it one after the other thru call txn. It is the same, howmany ever trx u wabnt to post thru BDC.

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.

How to Select More then 1000 values in Multi-Select prompt!!!

Hello Users,
I have Scenario where i have to pass all the values from prompt to report and the values in the prompt are coming from session variable, so whatever value access user has the report will run with that only...
Now the question is that Multi-Select Prompt is not able to take more then certain values, so is there any way that we can increase the limit for selected values??
in-short how to increase the limit for selected values in multi-select prompt??
Thanks In Advance!!!

Hey David,
The Scenario is like, we have data level security on "Unit" attribute. now based on the user selection when user logs in he should able to see the report only for those units which he/she has access.
in total we have 1800 units available, now for 5-10 units access is fine, but the question will arise when user will not have only some units access from 1800 units.
because report will not take those values from the multi-select prompt reason is that multi-select prompt is not able to take more then certain values in selected side.
now in multi-select until-unless u have data coming in selected side those values will not pass. so i have kept the sql in default for that prompt.
so when user logs in he will able to see those values in selected side for the multi-select prompt, but when values increase from some level it's going automatically in un-selected side.
i want everything on selected side of multi-select prompt.
Let me know if you need any further details.
