Form based on a procedure - question out parameter

hello,
I have created a form based on procedure:
PROCEDURE "PRC_REQ_CREATE" (
vuser_id in number,
vapp_study_id in number,
vinformation in varchar2,
vstate_id in number,
vaction_id in number,
vaccount out varchar2
the new form see all the parameters.
When I execute the form, the value for the out parameter is displayed on a separated window.
How can I display it in the vaccount field of the form ?
What can I do if I want to use this value in another form or report as a parameter?
Thanks for your help
Didier

I do know how you can use the out in a redirect.
Basics are:
Comment out the doSubmit in the pl/sql submit buffer,
declare your variables,
get your in variables that are being passed,
call the procedure directly from your code, storing the new variable.
do your navigation.
Or for an example, something like:
--- Type your PL/SQL code here...
doSubmit;- This is the default handler
--- ...and here, thanks...
declare
v_appt_in number;
v_appt_out number;
l_target varchar2(300);
blk varchar2(10):='DEFAULT';
begin
v_appt_in:=p_session.get_value_as_number
(p_block_name=>blk,p_attribute_name=>'A_V_APPT_ID');
appt.arrive_no_show(v_appt_in,v_appt_out);
l_target :=
'portal.wwa_app_module.linkp_arg_names=_moduleid&p_arg_values=1147314217';
l_target := l_target || '&p_arg_names=APPT_ID&p_arg_values=' || v_appt_out;
l_target := l_target || '&p_arg_names=_APPT_ID_COND&p_arg_values==';
PORTAL.wwa_app_module.set_target(l_target);
return;
end;
To display it in the field, I'ld suggest using set_value...

  • Calling a form based on a procedure from a report

    I have a report and want the user to link to a form based on a stored procedure passing params from the report record. That I can do using the link option. But to complicate matters I have more than one form based on a procedure and depending on values in the reports data depends on which form will be called (passing values to the form (all based on stored procedures).
    How can I do this ?
    Any advice would be really appreciated.

    If you want to display other HTML page after successful submission, you need to use
    either go or call method.
    I created a form on SCOTT.EMP and a report on SCOTT.EMP and the report accept a parameter for
    the deptno. Here is my on successfull submission code:
    declare
    l_dept number;
    l_url varchar2(2000);
    begin
    l_dept := p_session.get_value_as_number('DEFAULT', 'A_DEPTNO', 1);

  • Help: FORMS based on stored procedures

    I am working on a FORM based on stored procedures. This particular FORM performs a query and generates say,
    customer_name, item1_sale, item2_sale and sum of the item1_sale and item2_sale.
    I'd like to know if there are ways that the query procedure returns to reference cursors that one with multiple records and one with the sums? The FORM will then be able to show rows of sales and the bottom row with show the sale totals.
    Thank you in advance.

    Francois,
    I just tried another way of getting the totals. I manually created a data block and add two items tot_1 and tot_2. I the item properties: I set calculation:
    calculation Mode: Summary
    Summary Function: Sum
    Sumary Block: BLOCK_A
    Summary Item: item1_sale etc.,
    I got a compile error:
    FRM-30377: Summary item must reside in single-record block or in same block as summarized item.
    Where do I catch this error?

  • How to display errror message in a form based on a procedure

    I created a single-level form based on a procedure. In this form, I would like to generate an error message inside of a custom button, so I used the following inside of that button:
    p_session.set_value (p_block_name => 'DEFAULT',
    p_attribute_name => '_STATUS',
    p_value => 'Please choose a valid chair from the popup icon.');
    Unfortunately, it returned a WWV-0000 error code without any error messages. I use that code in another single-level form based on a table/view, and it works fine, but I need a single-level form based on a procedure. Therefore, I want to know if that code snippet can be used in a form based on a procedure or not? Do we have any other ways to display error messages in pl/sql besides p_session.set_value(...);
    Thanks in advance.

    Somebody please response.

  • Help: FRM-40505 for a FORM based on stored procedures

    Hi,
    I am working on a FORM based on stored procedures. When it performs a query, it actually returns record, but still comes with the message FRM-40505: ORACLE error: unable to perform query. Any recommendations on the possible coding area to check?
    Thank you in advance.
    Jimmy

    Jimmy,
    To base a block on a stored procedure is not a simple task because it depends on the .....
    .... stored procedure !
    If you do not provide much information (like the famous stored procedure), we could not do anything for you.
    As much information you provide, as much chance we have to understand the problem.

    Re: Error
    Passing OUT parameter to another form.
    You cannot retrieve the value of the OUT parameter from the session object because after executing your procedure,
    the value passed out using the OUT parameter is not loaded in the session object.
    But you can still achieve what you are trying in the following way.
    Let's assume that your procedure has the following str :-
    procedure proc1 (p_in in varchar2,
    p_out out varchar2)
    is
    begin
    /* your processing statements
    end;
    Say, the name of the field, in the 2nd form, where you need to pass the out parameter value is VALUE_FROM_OUT.
    1> Edit the form on procedure proc1
    2> Select the submit button in the left frame and for the PL/SQL button handler choose Submit action.
    3> In the adjacent textarea, comment out the doSubmit statement and use code given below :-
    declare
    l_p_in varchar2(32767);
    l_p_out varchar2(32767);
    l_url varchar2(2000);
    begin
    l_p_in := p_session.get_value_as_varchar2(
    p_block_name => 'DEFAULT',
    p_attribute_name => 'A_P_IN');
    execute immediate
    'begin <schema>.proc1(:b_in,:b_out); end;'
    using in l_p_in, out l_p_out;
    l_url := 'http://<host>:<port>/pls/<dad>/<portal-schema>.wwa_app_module.link?p_arg_name=_moduleid&p_arg_values=<module_id>&p_arg_names=VALUE_FROM_OUT&p_arg_values='||
    <portal-schema>.wwv_standard_util.url_encode(l_p_out);
    <portal-schema>.wwa_app_module.set_target(l_url,'CALL');
    end;
    NOTE :
    ======
    In the code given above, replace
    <schema> with the schema name that owns the procedure proc1
    <host> with webserver host
    <port> with the port of your webserver
    <dad> with the portal dad
    <portal-schema> with the name of the portal-schema
    <module_id> with the module of the 2nd form i.e. where you need to pass the value of the out variable.
    You will have to grant execute privilege on procedure proc1 to your application schema,
    if the procedure proc1 lies in a schema other than the application schema.
    4> Finish editing the form.

  • How to autopopulate fields in a portal form based on database procedure?

    Dear gurus, I am a newbie to the portal world and i have a rather unique problem. I have searched online but still cant find a solution to my problem. I have a portal form (AS version 10.1.4) based on a db procedure that accepts only one parameter. The form has about 12 fields, two of which are combo boxes. Because of the relationship b/n combo box 1 and combo box 2 and the rest of the form fields, the user has to start out by selecting a value in combo box 1. This auto populates combo box 2 (based on the previous selection). However, when the user selects a value from the populated combo box 2, this is supposed to trigger an action to query the database and retrieve values for the remainder of the form fields and populate them accordingly.
    I tried to use p_session.get and set values but discovered that one cannot do this with form fields that are based on a procedure. I could write javascript to call a database procedure but i am not sure how to pass the return values from the database back to the javascript routine and then populate the remaining fields accordingly.
    HELP ME PLEASE!!!
    Thanks

  • Calling Oracle Stored procedure with OUT parameter from ODI

    Hi,
    I called an oracle stored procedure with following anonymous block in the ODI procedure.
    Declare
    Status varchar2(10);
    Begin
    OTM.DeleteTarget('E_KPI_TARGET_VALUE', Status);
    End;
    I want to capture the OUT parameter STATUS value in a project level variable.
    And based on its va;lue I would like to choose between 2 interfaces in my package.
    Please help me in doing this.

    Hi,
    For that kind of situation I commoly use:
    1) one step with:
    create or replace package <%=odiRef.getSchemaName("W")%>.pck_var
    Status varchar2(10);
    end;
    * transaction 9, for instance
    2) step
    Begin
    OTM.DeleteTarget('E_KPI_TARGET_VALUE', <%=odiRef.getSchemaName("W")%>.pck_var.Status);
    End;
    * transaction 9
    3) then, at an ODI variable, use a refresh like:
    select <%=odiRef.getSchemaName("W")%>.pck_var.Status from dual
    at same logical shema where the package was created.
    Does it make sense to you?

  • New Window for Form called from a form based on a procedure

    Hi
    I have a form that is based on a procedure that asks for an employee number. The number is then passed to the procedure. The procedure then calls the next form passing in the employee number.
    This works however I would like the form called from the procedure to open in a new window while still being able to pass in the employee number as a parameter.
    Is there a way to do this? I have tried looking at wwa_app_module.new_instance & wwv_media.show_newwindow but I these only take the moduleid, I can't see how to pass in the employee number at the same time.
    Any help would be appreciated.
    Thanks
    Belinda

    Hi,
    You can pass parameters like this
    wwv_redirect.url('SJAYARAM_9042F.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=1060253649&p_arg_names=deptno&p_arg_values=10&p_arg_names=_deptno_cond&p_arg_values=%3d');
    In this example the parameter deptno is passed with a value 10 and conditional operator '='
    Hope that helps.

    Also in my project I've executed without problems others procedures using in-parameters and out-parameters, but this one causes me some problems:
    OADBTransactionImpl dbTx = (OADBTransactionImpl)getTransaction();
    String sql = "xgpv_utl_cot.get_expense_commission(:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11); end;";
    // create statement defining prefetch DEFAULT num rows
    cs = dbTx.createCallableStatement(sql, OADBTransactionImpl.DEFAULT);
    try{ // call statement
    // register the type of the out param - an Oracle specific type
    cs.setInt(1, cotizacionId );
    cs.setString(2, yes);
    cs.setInt(3, esqFinId);
    cs.setString(4, estadoCivil);
    cs.setDouble(5, valorBase);
    cs.setDouble(6, anticipo );
    cs.setDouble(7, capacidadCompraNeta);
    cs.setDouble(10, totalCredito);          //IN-OUT param
    cs.registerOutParameter(8, OracleTypes.DOUBLE);
    cs.registerOutParameter(9, OracleTypes.DOUBLE);
    cs.registerOutParameter(10, OracleTypes.DOUBLE); //IN-OUT param
    cs.registerOutParameter(11, OracleTypes.LONGVARCHAR);
    cs.execute();
    ocs = (OracleCallableStatement)cs;
    String status = ocs.getString(11);
    if ( !("1".equals(status)) ){
    ... do someting

    I was thinking that maybe the in-out parameter might been causing this error, maybe I didn't declarated it correctly.
    Can you help me?
    Thanks in advance....
