How do I pass a null value to the reportDocument?

I'm using CR 2008 and VS 2005.
I am using a stored procedure as the datasource for one of my report, which we run using the C# API.   The stored procedure is expecting a NULL in certain cases and I find I cannot pass a NULL with my current code:
// Here I get the parameter
// If we are dealing with an empty string or a NULL value, let's give it
                        // a value of a space so that Crystal's DLLs don't choke.
                        if ((value.Length == 0) || (value == "NULL"))
                            value = " ";
                        arrParams.Add(value);
Object strParam = arrParams<i>;
this.reportDocument1.SetParameterValue(num, strParam);
The stored procedure parameter type is INT so in the report it shows up as NUMBER.
How do I get a NULL value to the stored procedure?
Thanks.

See if this does the trick:
Dim crParameterDiscreteValue As New CrystalDecisions.Shared.ParameterDiscreteValue()
crParameterDiscreteValue.Value = Nothing
C# would look something like;
CrystalDecisions.Shared.ParameterDiscreteValue crParameterDiscreteValue;
crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();
crParameterDiscreteValue.Value = null;

How do I set a NULL value for the parameter field

Hi
I've another question. I'm going to set single values for parameter fields.
// e.g. set today for StartDate parameter field
fc.setCurrentValue("", "StartDate", new Date());
It should be possible to set a NULL value for date parameter fields.
fc.setCurrentValue("", "StartDate", (Date)null);
But this do not work. How do I set a NULL value correctly?
Thank you in advance.
Best regards,
Thomas

First question - is it a stored procedure parameter?
You can't set a regular parameter field value to a null value.
There was an issue with old version of the JRC, where it was allowing null to go through, but had unexpected behavior at times.

How can I pass Flex Field value to the Call Wrap Up screen?

Hello helpers,
I am trying to get a value from the 'Flex Field' passed over to the 'Call Wrap Up' screen by using Form Personalization.
Oracle was configured by a subcontractor and therefore I do not know what the exact name of the textfield is in the Flex Field however the label is 'Method of Contact'. When i set 'Show Custom Events' to 'On', I get the response: 'CSXXXRC.INCIDENT_TRACKING.STATUS_CODE:WHEN-NEW-ITEM-INSTANCE' When i enter a value in the Method of Contact field in the Flex Field.
Can anyone help?
I am a complete Newbie to Oracle.... I only know a bit about Oracle Form Personalization.
Any help would be much appreciated,

How can i pass second text value to the procedure.

Hi ,
I have used APEX_ITEM.TEXT(1,null) Item_name,APEX_ITEM.TEXT(2,null) file_name in a sql query and i should pass these two text value as a input parameter to the Procedure.
So in Process i have written code like
FOR i IN 1 .. APEX_Application.g_f01.COUNT
LOOP
generate_report_data(APEX_Application.g_f01(i)
,APEX_Application.g_f02(i)
END LOOP;
COMMIT;
if i enter values in two text columns then two values are passing to a procedure it's fine.
Here the issue is if i leave the first value as balnk and enter the 2 nd value like Xyz then click on a submit button
so 2 nd value also passing null to the procedure..
please anybody guide on this issue..
Thanks in advance..
Regards
Narender B

Hello Narender,
>
Here the issue is if i leave the first value as balnk and enter the 2 nd value like Xyz then click on a submit button
so 2 nd value also passing null to the procedure..
>
This is happening because of FOR i IN 1 .. APEX_Application.g_f01.COUNT in your procedure:
>
FOR i IN 1 .. APEX_Application.g_f01.COUNT
LOOP
generate_report_data(APEX_Application.g_f01(i)
,APEX_Application.g_f02(i)
END LOOP;
COMMIT;
>
FOR i IN 1 .. APEX_Application.g_f01.COUNT this loop will take only those values of apex_application.g_f01 into consideration whose value is not null.
Hope it helps!

How can I pass a custom value to the ecommerce invoice?

I would like to pass a barcode or an image to the ecommerce invoice once they buy my product. The idea is that they would print the email or pdf attached to it and reclaim their products on my physical store in case shipping is not allowed for their area. Is this possible?.

Hey Klaye,
I'm not sure if that php generator would work on the CRM because from what I understand it only uses javascript. I found these websites that might interest you:
http://parall.ax/products/jspdf (a javascript pdf generator)
http://www.atlantawebdesignga.com/adobe-business-catalyst-developer/how_to_get_business_ca talyst_e-commerce_to_do_the_impossible (an ecommerce "hack")
My plan was combining both methods plus a jquery barcode generator to insert the pdf in the ecommerce invoice, but your method seems better. Have you tested it? Does it work with the {tag_invoicenumber}?.
I haven't had the time to work on this because I'm working for some clients right now. But if I do get something to work I'll post it here. Hope that helped.

Passing null values to the attributes of a CAF operation

Hi,
In CAF I am trying to fetch data through Web Service. For this I need to pass null value for the attributes of the operation.If I set the value to null it gives me missing parameter as the error.
Can anyone tell me how to pass null values to the attributes of a CAF operation?

Hi Xavier,
Declare the two variables of type if_wd_contex_node for e.g. lv_node and if_wd_context_element for e.g. lv_element. Now in the first one lets say lv_node get the refrence of dynamically created node like:
lv_node = wd_context->get_child_node('<node name>').
Then get the refrence of element like:
lv_element = lv_node->get_element( ). (You can also pass index as parameter check the method API)
then just set the value of attribute you want like:
lv_element->set_attribute( exporting name = '<attribute name>' value = '<your value>').

Pass a null value to a JDBC stored procedure call?

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..

How to select instances without null value?

hye all,
i need to do th ereprocessing data whereas i have to select the instances without null value from the database..
for example:
id name
123 izza
345 alex
567
the id = 567 contain null value..so..its automatically will not be selected from the database...
how about if it have about 10 or more attributes to be selected..
how can i work with the SQL thanks..

Hi,
Query for your example should like like this:
SELECT * FROM <your_table>
WHERE name is null;
how about if it have about 10 or more attributes to be selected..
If using 10 or more attributes you mean 10 or more columns with null use this:
SELECT * FROM <your_table>
WHERE <col1> is null AND <col2> is null etc...Peter D.

Is it possible to pass a null value to a method?

is it possible to pass a null value to a method?
like this
public String getParameterXX(String testvalue)
String strX = "whatever";
if(testvalue!=null)
strX = strX + " man " ;
Is this possible ?
is this legal
String i = getParameterXX(null);

I also ran a similar code using null in a method, it just considers null as another string and concatenates it so
public String getParameterXX(String testvalue)
String strX = testvalue+"whatever";
return strX;
public static void main(String [] args)
Test tt = new Test();
String i = tt.getParameterXX(null);
System.out.println(i);
Gives me "nullwhatever"

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!
Edited by: Najla on Apr 1, 2013 10:37 PM

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

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.
Thanks in advance.
