Get the returned OUT value from Pl/Sql Procedure in AppMod

Hi,
I am using jdeveloper 10.
In the database i have a procedure like this :
procedure test (v1 in out number,
v2 in number);
And am calling this procedure from application module in this way :
Object[] procArgs = new Object[]{v_1,
v_2
try {
callStoredProcedure("test (?,?)",procArgs);
I want to read the value of the v1 parameter after procedure is executed. Can anyone tell me how can i do it from application module ?
Thanks in advance,

After the call of the proc the value should be in procArgs[0]

How do I return two values from a stored procedure into an "Execute SQL Task" within SQL Server 2008 R2

Hi,
How do I return two values from a
stored procedure into an "Execute SQL Task" please? Each of these two values need to be populated into an SSIS variable for later processing, e.g. StartDate and EndDate.
Thinking about stored procedure output parameters for example. Is there anything special I need to bear in mind to ensure that the SSIS variables are populated with the updated stored procedure output parameter values?
Something like ?
CREATE PROCEDURE [etl].[ConvertPeriodToStartAndEndDate]
@intPeriod INT,
@strPeriod_Length NVARCHAR(1),
@dtStart NVARCHAR(8) OUTPUT,
@dtEnd NVARCHAR(8) OUTPUT
AS
then within the SSIS component; -
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

Below execute statement should work along the parameter mapping which you have provided. Also try specifying the parameter size property as default.
Exec [etl].[ConvertPeriodToStartAndEndDate] ?,?,? output, ? output
Add a script task to check ssis variables values using,
Msgbox(Dts.Variables("User::strExtractStartDate").Value)
Do not forget to add the property "readOnlyVariables" as strExtractStartDate variable to check for only one variable.

Pcr To Get The Wage Type Value From Previous Years Master Data Records

Hi
I have an issue related to pcr. I want to get the value of a wage type from previous year and it has to be added to another wage type. Tried to write pcr by using the operation TABLE. But i am not able to get the previous years data. Request to help in writing the PCR for the issue.
Thanks
EKP Yadav

1 - Create an "Information WT" that will be saved into RT but that has no impact on net pay.
2 - Create a PCR that will be activated on the last pay of the year to read the WT you want and transfer it's information into your Information WT.
3 - Create a PCR that will read the last payroll results (activated with function PLRT) and transfer into the Input Table (IT) the Information WT.

I can not get the pop out menu from the tools to work. It looks like they are not loaded

Can someone help me know how to get the tool pop out menu to work. It looks like they are not loaded.

You do have to click and hold down on any tool icon with a small triangle in the lower right.
The second method is to right-click on the tool.

Returning result sets from PL/SQL procedure to client app.

I was wondering if its possible in Oracle PL/SQL to DECLARE, OPEN a cursor and exit
the procedure without closing the cursor
and then retrieve the resultset from
the client.
Pl let me know..
null

Yes, you need to use one OUT parameter in your PL/SQL procedure
to pass the cursor variable to
Java code. You can also return that as a return variable of
PL/SQL function. Get the cursor variable from the resultset using
Types.CURSOR data type and then proceed as usual.

Get the report list in a PL/SQL procedure

Hi to all,
I need to get the list of the personal report of a specified user in a PL/SQL procedure, is this possible?
My procedure should delete not "standard" report of a specified portal user.
Then i must have the list of all user's reports and after do my delete logic.
Jhon Dhon

Jhon -
It sounds to me that what you want to do is have a list that is generated based upon the identification of an individual. You can do this a number of ways, but I think you would want to write a straight query to accomplish this rather than a PL/SQL procedure. A query to accomplish what you're looking to do would look something like this:
SELECT
person_name,
person_id_number,
other info you need to see in the output
FROM
table_name (that contains the info you need to see)
WHERE
conditional clauses to obtain only data you wish to see
AND :p_person_id = table_name.person_id_number
The AND clause line will return the employee the user wishes to see based upon that person's ID number. This information is asked for in a parameter form before the report is run. The :p_person_id is referred to as a bind variable. You can read more about this on Metalink or OTN.

hi
1) place a field adjacent to your value field on which F4 is operated
so now you will have 2 fields.
iam considering it as for ex: field1 & field2

e_dynpfld_mapping-fldname = 'F0002'.
e_dynpfld_mapping-dyfldname =   -

APPEND e_dynpfld_mapping TO t_dynpfld_mapping.

Getting the last selected value of the combo - very very urgent...........

On my panel i have a jcombobox in upper half(which displays say the address type.) and few text fields on the lower half(which displays the add details). when the user selects a value in the combo box the text fields are populated based on the selection. The user can change the values displayed in the text fields. So before setting the new values in the text fields the last displayed values need to be saved.
I have an ActionListener for my combo which gives me the currently selected value by calling getSelecetdItem()
How can i get the last selcted value of the combobox without using any variable of my own.

To update the last displayed details(the address details say) i need to check what type of address the combo had previousely.....
when i display the panel first time the home address is set by default and i have a variable to hold this value..as the user changes the selection i update the variable...I don't want to use this variable..instead if i can get the last selcted value from the event that would be great...
thanks

Remote Object - not able to get the returned value from java method

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">
<mx:Script><![CDATA[

     var customChannel:Channel = new AMFChannel("my-amf", "http://localhost:8400/blazeds/messagebroker/amf");     cs.addChannel(customChannel);
     remoteObj.channelSet = cs;
public function writeToConsole():void {      remoteObj.writeToConsole(
"hello from Flash client");
      var returnedVal:String = remoteObj.setName().lastResult;     Alert.show(returnedVal);

     public void writeToConsole(String msg) {          System.out.println("SimpleRemoteObject.write: " + msg);     }
     public String setName(){          System.
out.println("Name changed in Java");
          return "Name changed in Java";
And I have configured destination in remote-config.xml
<destination id="sro">
   <properties>
    <source>SimpleRemoteObject</source>
    <scope>application</scope>
   </properties>
</destination>
Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.

Hi,
The executeQueryAsync method is “asynchronous, which means that the code will continue to be executed without waiting for the server to
respond”.
From the error message “The collection has not been initialized”, which suggests that the object in use hadn’t been initialized after the execution of the executeQueryAsync method.
I suggest you debug the code in browser to see which line of code will throw this error, then you can reorganize the logic of the code to avoid using the uninitialized object.

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.
