Best Way to call Dynamically an stored procedure

Hi Guys,
Here my question... I need to call dynamically to an stored procedure...
- the stored procedure can change, the name , the number of parameters
- the called stored procedure can contain output parameters.
lv_sql := 'BEGIN '|| lv_program_name || ' ( ' || get_parameters(lv_program_name) || '); END;';
get_parameters function generates an string depeding on the number of parameters that this function reads from the
oracle dictionary (i.e: ':1,:2,:3,:4......... )
then the dynamyc code must be executed as follow
execute immediate lv_sql
using .................................?????????
The issue that I am facing is how to handle the "using clause".... since before that I ran the program I dont know how many parameters the program will have...
Please your help... (or suggestion to solve in another way)
...:::OKMMAN:::...

About "Satyaki_De " comment,
Since I dont know the stored procedure to be called, I cant know the number of parameters and its type to be returned... I mean.. to use the clause "using ...." in static way...
By now, I am creating dinamically a stored procedure... I am building a stored procedure that calls to the "unknown" stored procedure... reading the data dictionary and building dynamically the "Using...." clause... but I dont like ... since probably in production enviroment I will not have that kind of grants....
Regarding the link... I didn't know that new type... ! That's will solve the type issue... but still is pending the number of variable to provide to the "using" clause...

  • Best way to return structured data?procedure or function?

    Hi everyone.
    I cannot choose the best way to return, from java stored procedure, some data.
    for example , which is best way to write this method:
    public STRUCT function(input parameters) { STRUCT result     ...   return result; }
    or
    public void procedure(input parameters, STRUCT[] struct) { STRUCT result     ...   struct[0] = result; }
    in the last way, the wrapper obviously will be: CREATE PROCEDURE name(... IN datatype, data OUT STRUCT)
    Which is best way in efficiency ?
    thank you ;)

    da`,
    By "efficiency", I assume you mean, best performance/least time.
    In my experience, the only way to discover this is to compare the two, since there are many factors that affect the situation.
    Good Luck,
    Avi.

  • Dynamic SQL Stored Procedure call in Pro*C Application

    Hello All
    Could you help with a sample Pro*C program (or snippet) which has a dynamic call to a stored procedure? The procedure to be called is determined at run time and so also the number of parameters to it.
    Is this even possible using Pro*C?
    Thanks in Advance

    Hi Colin & Faust
    We found sample pro*c programs for dynamically calling PL/SQL blocks but not for dynamically calling stored procedures.

  • Call to Oracle stored procedure that returns ref cursor doesn't work

    I'm trying to use an OData service operation with Entity Framework to call an Oracle stored procedure that takes an number as an input parameter and returns a ref cursor. The client is javascript so I'm using the rest console to test my endpoints. I have been able to successful call a regular Oracle stored procedure that takes a number parameter but doesn't return anything so I think I have the different component interactions correct. When I try calling the proc that has an ref cursor for the output I get the following an error "Invalid number or type of parameters". Here are my specifics:
    App.config

    I defined a function import for the stored procedure using the directions I found online by creating a new complex type. I don't know if I should be defining the input parameter, WindfarmId, in my app.config? If I should what would that format look like? I also don't know if I'm invoking the stored procedure correctly in my service operation? I'm testing everything through the rest console because the client consuming this information is written in javascript and expecting a json format. Any help is appreciated!

    Making the change you suggested still resulted in the same Oracle.DataAccess.Client.OracleException {"ORA-06550: line 1, column 8:\nPLS-00306: wrong number or types of arguments in call to 'GETWORKORDERSBYWINDFARMID'\nORA-06550: line 1, column 8:\nPL/SQL: Statement ignored"}     System.Exception {Oracle.DataAccess.Client.OracleException}
    I keep thinking it has to do with my oracle.dataaccess.client settings in App.Config because I don't actually put the WindfarmId and an input parameter. I tried a few different ways to do this but can't find the correct format.

    Am I do something wrong or miss something???
    I've checked the examples on the OTN HOW TO, and searched in the JDeveloper Forum but unable to find an answer,
    Please anyone can help???
    Thanks a lot
    With Regards,
    Hayat

    Here's an example application that illustrates how to do this. I haven't had a chance to writeup a little paper to go with it yet, but will as soon as I have a chance.
    http://otn.oracle.com/products/jdev/tips/muench/storedproc/CallStoredProc.zip
    See the "callStoredProcedure" method in the application module in the Model project.
    See the "callStoredProcedure" method binding in the binding container of the "CallStoredProcedure" data page.
    Notice the name "event_callStoredProcedure" of the (Call Stored Procedure) button on the CallStoredProcedure.jsp page which triggers the declaratively invocation of the method.
    You could also call the method from code in a custom data action.
    The code example illustrates how to create your own JDBC prepared statement for invoking the stored procedure, and doing it in a way that is efficient by keeping the prepared statement around across invocations.

  • Out of memory error when calling a java stored procedure multiple times

    Trying to run a PL/SQL loop calling a java stored procedure, I get the following error:
    "ORA-04030: out of process memory when trying to allocate 262188 byte callheap,ioc_allocate free)"
    (with some other error lines).
    The stored procedure does two major things:
    1) Open a socket to communicate with a server, of which it queries some data.
    2) Use JDBC (with the default DB connection it has, as a stored procedure) to write the results to a table.
    All socket connections, statements, etc. are properly closed and all memory should be garbage collected between each call.
    Can anyone offer an explanation or additional checks to make? I'm quite sure the code isn't causing the problem, since I've tried running it as a stand alone application (outside of Oracle) and didn't have any problems.
    Thanks.

    On top of what jschell says, this just looks wrong in terms of how Oracle's internal Java works as well.

    Is the db you are querying a different one to the one this Java is stored in?

    Well, there's certainly something about that line that it doesn't like.
    I'm not really familiar enough with MySQL to remote-debug this one for you, but it seems to be dying while trying to reconcile that call to its metadata for the sproc. Check the sproc declaration -does it return a single out value? Or does it have a single out value in the parameter list (not the same thing, I think) ? And so on.
    Also, with the amended call that I provided is the failing stack trace identical, or slightly different? If different, could you post that too please?
    Finally, do you have a known good sproc call that you can sanity check against? Perhaps take one of the examples from the MySQL site and check that that will work with their reference code?

  • Best way to call EJB - Servlet or Tag Library

    Hi,
    What is the best way to call an EJB from a JSP? We are using Weblogic 7.0(moving to 8.1 beta). WE have a form on a JSP that needs to get data from an EJB. Our flow goes from JSP --> Controller servlet or tag library -->EJB "Bean" Controller ---> EJB. The specfic EJB we need to populate drop downs and fields will be called by a bean controller. Is it better to call the bean controller using a tag library in the jsp or go to the controller servlet to get the data? If servlet is the answer, where do I lookup the EJB Home and call the create from within the servlet? Any help would be greatly appreciated!!
    Thanks!

    IMO, if you are following some design patterns, like the MVC framework, the best thing is to populate the model(entities that contain the business data) and call the respective getXX methods from the model on the JSP page. The reason for doing so is to keep JSP pages away from any other work other than to just display the business data contained in the respective business entities.
    The model can be populated in the servlet and either set in the request or session attribute as per the requirement.
    The EJB can be looked up in the servlet as and when required. I would suggest to make use of the Service Locator Pattern to do a look up for the EJB Remote Interface and accordingly make the business calls.
    Hopefully this answers some of your questions.

  • What is the best way to call a pageflow action from JavaScript?

    What is the best way to call a pageflow action from JavaScript?
    Thanks,
    John

    John,
    How would I do this from a grid??? Unfortunately there are no JavaScript attributes
    on any of the grid tags that I can see.
    Thanks,
    John

    If you want to put up a confirm dialog before calling an action from
    an
    anchor it is done as follows.
    Here is an example from code of mine that deletes a customer order,if
    the
    user confirms the delete. I pass the order id as a parameter.
    - john
    Here is the JavaScript -
    function confirmDelete() {
    if(confirm('Continue with order delete?'))
    return true;
    else
    return false;
    Here is a sample anchor tag -
    <netui:anchor action="requestToDeleteOrder" onClick="return
    confirmDelete(); return false;">
    Delete
    <netui:parameter name="orderId" value="{container.item.orderId}"/>
    </netui:anchor>

    Thanks for the replies. I figured it was going to require buildingmy own
    url
    to call the action. I had hoped there was an easier way to do it.Rich,
    the
    reason I want to do this is because I want to call the JavaScript
    function
    confirm()
    when a user clicks on a link (in a repeater/grid) to drop a record,I only
    want
    to call the drop action if the user confirms the drop. Maybe thereis a
    better
    way to do what I am trying to do??? I really appreciate any help
    you
    guys
    can
    give me on this, I am pretty new to this sort of stuff.
    Thanks,
    John

    Thanks,
    JohnTry figuring out the URL to the pageflow action, create a hidden
    form
    in the
    page, then use JS to submit the form. Why would you want to though,
    isn't
    the server going to want to send you to the next page?
