Error while selecting NULL value from Popup Key LOV(numeric or value error)

Hi,
I have a item P1_DEPTNO with following properties.
P1_DEPTNO - Popup Key LOV (Displays description, returns key value)
LOV - P1_DEPT_LOV
select deptname d, deptno r from deptP1_DEPTNO item properties
List of Values
Named LOV - P1_DEPT_LOV
Display Null - Yes // changed to Yes, so that it can accept NULL values.
Null display value - NULL
Null return value -   (blank)PL\SQL Process -
declare
v1 number;
begin
if :P1_DEPTNO is null OR :P1_DEPTNO = '' then
    v1 := 0;
else
    v1 := :P1_DEPTNO;
end if;
// rest of the PL\SQL process
end;Now, when I run the page and select NULL value from Popup LOV and submit, I get the following error.
ORA-06502: PL/SQL: numeric or value error: character to number conversion error.When, I select any other value other than NULL, then it's working perfectly fine.
Only in case of NULL value, I am getting this error.
ANY idea, why this error is coming??
Thanks,
Deepak

Hi Varad,
I did the following change
Null display value - (blank) // by default it is displaying '%' in the select this
Null return value - -1
but when I select % (null value) from the popup list, it displays the return value -1 in the text field.
My question is why it is displaying the return value -1 in the text field...*It should display the display value in the text field (i.e blank in this case)*
then, I did the following change
Null display value - (blank) // by default it is displaying '%' in the select this
Null return value - // a single space, so that when I select %(null value) from the list, it should display blank in the text field...
then I did the following change in the PL\SQL process.
PL\SQL process
declare
v1 number;
begin
if :P1_DEPTNO = ' ' then // -- checking the value of single space ' ' when we select %(null) in the popup list, BUT even I select %(null), control is not coming here.
    v1 := 0;
else
    v1 := :P1_DEPTNO;
end if;
// rest of the PL\SQL process
end;Thanks,
Deepak

Need help Take out the null values from the ResultSet and Create a XML file

hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.

Again i have to display it in a jsp page from table.
The problem am facing was,how can i display only the values in a row.it must not display the null values and the crresponding column name.
Or any other way is their like below
How i can retrieve only the selected check boxes from tht jsp file.and store in backend.
Thanks in Advance

satheesh kannan

Here is a rough example that may give you some ideas:
On the JSP page:
<%if(myData.getFirstName()!=null){%>
Your First Name'
<input type="text" name="firstName" value="<%=myData.getFirstName()%>">
<%}%>
In the servlet:
String firstName= request.getParameter("firstName");
if(firstName!=null){
//write it to the database
}

How to avoid the null values from xml publisher.

I am creating a report which have the claim numbers with the values CLA001,CLA111,null, null . when i preview my report it is showing some spaces for null values also. How can i avoid the spaces from the report.
I am giving for loop for the claim numbers in the template.
<?for-each:ROW?> <?sort:CLAIMNUMBER;'ascending';data-type='text'?>
<?CLAIMNUMBER?>
<?end for-each?>
Please help me out to solve this problem.
Thanks,
vasanth.

Hi Sheshu,
According to your description, you are experiencing the null values and infinity values when browser the calculated measure, right?
Based on my research, the issue is caused by that dividing a non-zero or non-null value by zero or null. In this cases, we need to check for division by zero to avoid this situation. Here is the sample query for you reference.
IIF(
Measures.[Measure B]=0,null,
Measures.[Measure A] / Measures.[Measure B]
If you have any questions, please feel free to ask.

Unable to select the value from a list item in forms 6i

Hi ,
I'am using forms 6i. I have created a list item in my form as below.
Item_type = list item
list style - popup list
elements in list - A, B, C,D
When I open the form all the above values are displayed for the list item. But I'am unable to select the item( either A,B,C,D).
Please let me know if I need to add any thing else programatically to acheive this. The block on whixh these values are diplayed is a datablock.
This is very urgent. Any suggestions would be of great help.
Thanks
Deepthi

If you have a list item where you have:
Display A value 1
Display B value 2
Display C value 3
Display D value 4
If want to initial the value of the item to be A, you can set the initial value of the item to 1 in the property pane.
Otherwise in an initialisation triger have
:block.list_item := 1;

How to get the selected values from multiselected list

Hi,
I have a multiselect list displaying all the years from 2003 to 2008 (used dynamic LOV). The user can choose one or more years as per his needs, and then when user clicks on the link the selected values of the list are to be captured and a pop up page of a Discoveror report needs to be opened where these years get passed as a parameter. I tried several methods to capture the value, but either one or all are getting passed but not exactly what the user has chosen.
This is how it looks:
P2_FISCAL_YEAR is a multiselect list containing values from 2003,2004... 2008
If user chooses 2004 and 2007
then I want the url to capture these values and pass as parameters for my discoveror reports. as '&qp_fiscal_year=2004,2007'
Any help is appreciated!
Thanks in advance,
Sapna.

How can I delete null values from List Item?

Hi Friends,
I used List item for field job_Type, I entered values in List item at design time through property pallet. When I run form I will see null values in this List Item.
How can I remove these null values from the List?
Best regards,
Shahzad

Dear Shahzad,
It can be removed by adding the following code in the When-new-Form-Instance.
Set_item_property('List name', required, property_true);
:block_name.list_name := <put your default value here>; (If you didn't oput the default value, then you will get some problem and the cursor may not navigate away from the list).

How to replace NULL values from main table

Dear all,
I like to remove the NULL values from a main table field. Or the question is how to replace any part of the string field in MDM repository main table field.
e.g. I have a middle name field partly the value is NULL in some hundreds of records, I like to replace NULL values with Space
any recommendation.
Regards,
Naeem

Hi Naeem,
You can try using Workflows for automatically replacing NULLs with any specific value.
What you can do is: Create a workflow and set trigger action as Record Import, Record Create and Record Update. So, that whenever any change will occur in the repository; that workflow will trigger.
Now create an assignment expression for replacing NULLs with any specific value and use that assignment expression in your workflow by using Assign Step in workflow.
For exiting records, you will have to replace NULLs manually using the process given by Preethi else you can export those records in an Excel spreadsheet which have NULLs and then replace all NULLs with any string value and then reimport those records in your MDM repository.
Hope this will solve your problem.

Varun

How to find out the null values in table

hi experts,
my version is oracledb10g:

insert into ex1(e)
count will be: 2
i can easily found out the value 'e'.
so my question is:
how can i found out the null values in the table and i want to delete the null values from the table.

delete from <table_name>
where <column_name> is null;Ideally you'd just place a NOT NULL constraint on the column in question, thereby prohibiting NULL values from entering into the system (assuming your business requirement is that the column MUST always have a value).

How to put the null value at the last of a select list

Hello,
I have a select list with a null value, I want the null value to be the last value in the list. It always appears in the top of the list, Desc and Asc order is not working.
Thank you in advance!

Hi,
Edited by: Howard (... in Training) on Apr 2, 2013 1:xx PM
The statement - I don't think it is possible to arrange the order of the null option in a select list.- is close. You can't control the order of the Null value if you add the Null value through the GUI. However, it can be added and controlled as part of a SELECT ...
One way is to add NULL to the "SELECT". Here the Yes/No are hard-coded but they could have been selected from a table:
select d, r from
select 'YES' d, 'Y' r from dual
union all
select 'No' d, 'N' r from dual
union all
select Null d, '<Null>' r from dual
) order by 1 desc NULLS lastHoward

How to get the values from popup window to mainwindow

HI all,

   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

Uday
