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.

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.

Not to display the null values from data base

Hiiii.
In a jsp file i have ten check boxes.The jsp file is mapped to a servlet file for parameter requesting and to
store it in DB.
The unchecked box values has null values.All the values are store in a Mysql DB table.
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
regards,
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 find out the null values in table

hi experts,
my version is oracledb10g:
i h'd simple doubts.
for eg:
create table ex1( e varchar2(20));
insert into ex1 (null).
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!
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

How can I avoid the null values in cross tab?

How can I avoid the null values in cross tab?

Hello Anindita,
Let me explain you the problem in detail.
I have selected User and Program as rows in the cross tab. In Summarized Field I am counting the Programs.
In DB I can have both User and Program null.
Letu2019s take these scenarios...
1) For a User, Program can be null
2) For a Program, User can be null
3) And both can be null.
A null Program does not give problem since Cross tab does not count the null values and in my case too, it remove the Program which are null from the Cross tab because of the counting its doing on Program. Hence scenario 1 and 3 is not a Problem.
Problem comes in scenario 2 (For a Program, User can be null).
In this case since Program is not null it will get counted and will be grouped under null user but I donu2019t want to show the null user Grouping in my cross tab.
"Suppress empty rows" and "suppress empty colums" does not help.
Thanks & Regards,

XML question on textnode null value

Hi,
I don't known XML use, I'm learning.
My question is
If in the DomDocument newsXML I append to "node" the newelement and a textnode, initially with not null value. Why, then, can't I setNodeValue to Null?
newelement:=xmldom.createelement(newsXML,element_name);
newnode:=xmldom.appendchild(node,xmldom.MAKENODE(newelement));
Textitem:=xmldom.createTextNode(newsXML,value);
newnode:=xmldom.appendchild(newnode,xmldom.MAKENODE(Textitem));
xmldom.setNodeValue(newnode,null); not possible!!!
Why?
Yet,
is There another way to append a leaf null in the tree of xml?
Thanks!

I maybe wrong about this because my XML is a little rusty, but I thing a Node is null when we create it. It is only by adding a TextNode to it that we make it not null.
If that's the wrong answer I will just suggest you visit one of the OTN XML forums which you can find here.
Cheers, APC

Null . Unable to understand the null value concept

Dear friends, I am very confusied about the behavior of ----"null"
and i take a String.The String value will come from data base ---- String inputString[This string value will come from database], In data base the value is null.
now i am checking if the string "inputString" is null --will perform a work if not then perform another work.
so--
inputStringFromUser.equals(null)
System.out.println("In if block");
else
System.out.println("In else block");
but it not working if the data base field is blank.
but if i do ---
inputStringFromUser==null)
System.out.println("In if block");
else
System.out.println("In else block");
it is working fine . why???
please tell me why it is happning.

I did not get any null pointer exception when i test
if(inputStringFromUser.equals(null)
y previous query have cleared.
But i fell i am little bit of confused for this ---
"can't invoke methods on a null reference, that gives
NullPointerException".Can any one please explain.Here's the deal and here's what they're trying to say without any metaphors...
inputStringFromUser is a String object right? the equals method is inherited from the Object object (java.lang.Object)
but if inputStringFromUser is null, it means there's no instance of that String object...so if it's null you cannot access the equals method...this is why you need to use the == operator to see if it's null.
hope that makes sense.

Missing XML elements are no longer treated as NULL value (MDM 7.1 SP04)

Hello,
We have a problem with importing XML files with missing XML segments (and hence missing XML fields) in XML file.
In MDM 7.1 SP03 (7.1.03.72), missing fields within a missing segment (so no tags at all for segment and fields) were still represented in the import manager as NULL value in the value mapping, making it possible to do value mapping and to import this NULL value into MDM (overwriting existing values in MDM).
As of MDM 7.1 SP04 (we are running 7.1.04.126) the missing fields within an missing segment are no longer represented in the import manager as NULL value in value mapping!
I don't know if that's a new 'feature' in SP04 but we are now running into following problem:
- We are importing customer data from ECC into MDM, where some segments are optional
- The fields within the (optional) segment are mapped to a multi-valued tuple field
- When we now import a customer that has values for the optional segment, the tuple field gets filled correctly
- When the optional data is now removed completely from the customer in ECC, we don't get that segment anymore in the XML file (this is how the Idoc works on ECC side, if all entries from the optionel segment are deleted then the complete segment is missing in the XML file)
- In SP03 we replaced the existing tuple records with the NULL value (leaving 1 empty tuple record, but this is known issue to SAP, so we've accepted this for the moment)
- In SP04 we cannot replace the existing tuple records anymore, since when complete segment is missing, the fields within that segment gets no value at all (in source values). So we are not able to replace the existing tuple records with NULL/nothing, leaving the 'old' tuple values in MDM!
Does anyone have solution for this (that also works with SP04)?
We already tried to replace the complete record in MDM (instead of updating it, this is possible since we always get the latest (and complete) status of a customer), but we are also mapping the remote key, and hence you are not allowed to replace the record during import!
Other solution could be to have PI add any missing segment into the XML message, but we first want to make sure that this cannot be handled within MDM Import Manager itself.
Thanks in advance,
Marcel Herber

Hi Marcel,
I haven't tried it with XML file but i hope it may help you.
long back i need to send one field with value null if it doesn't come in source file and if it comes then original value.
What i did, i loaded a file which does not have this field, so in MDM Import Manager, under source hierarchy i created a field say ABC and map this field with target field and its value Null with Null, i also save this property in map using configuration options-->Automap fields when loading map = Yes
So whenever a file come with missing field ABC, automatically this field get created and mapped with target field and its value Null with target Null. on the other hand, If this field actually comes in Source File(Delimited, Excel) ABC then this field with its original value gets map with target field value. That time it worked fine.
Just try and revert with result if it helps..
Else, using PI is the best option to create that missing segment into the XML message.

Grouping to display null values for all the missing dates

Hi SAP,
I am trying to display '0.00' value for all the missing dates in my crystal reports as follows:
17-Jan-14     40.00
18-Jan-14       0.00
19-Jan-14       0.00
20-Jan-14     80.00
However, my crystal report is showing as follows:
17-Jan-14     40.00
18-Jan-14       0.00
19-Jan-14
20-Jan-14     80.00
The missing dates with no data are group together and my '0.00' value is not. Kindly advise me the solution. The formula is shown as per attached.
Thank you.
Regards.

Hi,
Thanks for your reply.
Fyi, I am using a formula field in crystal report to display "0.00" for days in between as follows:
whileprintingrecords;
if Days_Between({Command.DocDate},next({Command.DocDate}),'dd-MMM-yy') = "" then "" else "0.00"
There is another formula field in crystal report to display the missing dates in between as follows:
whileprintingrecords;
Days_Between({Command.DocDate},next({Command.DocDate}),'dd-MMM-yy')
Below is my report custom functions:
Function Days_Between (datefield as datetime, nextdatefield as datetime, format as string)
' This function is only used to display what data is missing within a specified date range...output type is text
dim thisdate as date
dim nextdate as date
dim output as string 'output is the text display
dim daysbetween as number
dim looptimes as number
looptimes = 0
daysbetween = 0
output = ""
thisdate = datevalue(datefield) + 1
nextdate = datevalue(nextdatefield)
if nextdate - thisdate > 1 then daysbetween = nextdate - thisdate else daysbetween = 1
do
if nextdate - thisdate > 1 _
then output = output + totext(thisdate, format) + chr(10) _
else _
if nextdate - thisdate > 0 _
then output = output + totext(thisdate, format)
looptimes = looptimes + 1
thisdate = thisdate + 1
loop until looptimes = daysbetween
    Days_Between = output
End Function
The issue arise when when there is more than one missing dates in between but the null values ("0.00") displayed is only for the first missing dates and not for all the missing dates.
