Null Value in PI 7.1

Hi
I am working on Proxy to SOAP Scenario, I receive null value at the first instance when I display the Queue, and values after the null, and the values are coming from the different nodes, and mapping needs to be done at the different level too.
Example I receive the state vale as
1. null
2.CA
3.NV
in order to avoid the null value while mapping what is the function to use it, I used Remove context but still I receive the null value at the begining
Thanks

Hi PR,
In my case, because of this change in 7.1 a mapping which is working in 7.0 was resulting in wrong results in 7.1
I doubt this change was done by SAP in 7.1 for ease of use in UDF.
However, in your scenario try placing a remove contexts-split by value immediately after the condition it suppress the null.
Else provide me your condition in MM I will replicate and help you.
Also, try changing the context to a higher level
Venkat.

Geting null values from request

hi!
i m producing this code through out.println() method in my page and then using java script
i am submiting this page to another page
<td width="56%"><textarea name="question_no_1"></textarea></td>
<input name="question_no_1_radio1" type="radio" value="radio"></td>
<td width="59%"> <textarea name="question_no_1_ans1"></textarea></td>
<input type="radio" name="question_no_1_radio2" value="radio"></td>
<td><textarea name="question_no_1_ans2"></textarea></td>
<input type="radio" name="question_no_1_radio3" value="radio"></td>
<td><textarea name="question_no_1_ans3"></textarea></td>
<input name="question_no_1_radio4" type="radio" value="radio"></td>
<td><textarea name="question_no_1_ans4"></textarea></td>
but when i submit it to the other page and try to retrieve value of parameter "question_no_1"
through the bellow statement it shows a null value but i have given a value previously by
typing a question in it
System.out.println("the Body Of The First Question Is "+request.getParameter("question_no_1"));
can anybody help me what is going on here.
also if i try to normaly submit first page (ie <form="form1" method="post" action="other_jsp_page.jsp"> ) then the statement in the next page gives me the correct value but
i have to submit the first paper through java script.
if u want to see full detail of my code then go to the following link
http://forum.java.sun.com/thread.jsp?thread=309254&forum=45&message=1237097
thanx in advance

OK, your problem is that you are not submmiting the values to the other page. When you do the
--> document.forms[0].submit();
in JavaScript, the form has to action defined
--> <form name="form1" method="" action="">
So, the page does nothing. The line following the submit just changes the location of the page, IT DOES NOT POST the values.
One solutions is the following:
1.- define an action for your form:
<form name="form1" method="POST" action="'save_paper.jsp">
2.- Then create a JavaScript function that validates the fields and simply return "true" if the form is correct, and false if there is a problem (just a little modification of the one you have).
3.- Then modify your submit button:
Instead of:
<input type="button" name="Save" value="Save" onClick="validateField()">
Try:
<input type="SUBMIT" value="Save" onclick="validateField();">

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

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
}

JDBC MS Access--- cannot extract entry with null value with data type Meta

I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexception

The question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.

Index (or not) for excluding NULL values in a query

Hello,
I have table that can become very large. The table has a varchar2 column (let's call it TEXT) that can contain NULL values. I want to process only the records that have a value (NOT NULL). Also, the table is continuously expanded with newly inserted records. The inserts should suffer as little performance loss as possible.
My question: should I use an index on the column and if so, what kind of index?
I have done a little test with a function based index (inspired by this Tom Kyte article: http://tkyte.blogspot.com/2006/01/something-about-nothing.html):
create index text_isnull_idx on my_table(text,0);
I notice that if I use the clause WHERE TEXT IS NULL, the index is used. But if I use a clause WHERE TEXT IS NOT NULL (which is the clause I want to use), a full table scan is performed. Is this bad? Can I somehow improve the speed of this selection?
Thanks in advance,
Frans

Null values passed into the servlet

Hi all,
I keep getting null values for all the params that I pass into the servlet i.e. sqltype, producttype, process, instance etc....I have attempted to print some of them out on the screen but I keep getting the 'NullPointerException' error message...can anyone tell me what it is that I have down wrong in the below code?
If I run the servlet with method calls that have hardcoded arguments in them it works but not when I pass in the params from the URL...I am absolutley puzzled!

That section of the code references a cache to extract an item that has been requested by the user. If the item is not in the cache i.e. if(o1 == null) then it will call a class that generates that object and places that object into the cache. The second time the user makes the same call then they will be handed a cached copy of that object which is aimed to make the whole servlet call faster.
That section of the code works fine coz I have tested that separately. It is the reading in of the arguments that is causing the problem.

How to differentiate the EMPTY Records and Null Values in DSO

Hello....how is everyone here?? Ehehehe!
I try to load some data from the flat file which contains some EMPTY data and Null Values for the records. The data type for the InfoObjects of the fields "Quantity" is "number". The sample data from the flat file (CSV) are as below:
Food              Quantity
Hamburger -       12
Cheese        -       0
Vegetable      -               (Empty)
When I try to load the above sample data to the DSO, I get the results of the data as follow:
Food              Quantity
Hamburger     - 12.000
Cheese           - 0.000
Vegetable         - 0.000
In this case, how can the user differentiate whether the records is contain empty value of null values in DSO? This is kinda of hard to differentiate the both scenarios above. Is there any way to differentiate the scenarios described here?
Thanks alot =)

Hi Fluffy,
It depends on the initial values of the data type
The inital values For quantity/Currency/ Numbers it takes spaces as 0
for char it is SPACE
We cannot differeniate between space and null values.
IF you have to force this then define quantity as char and load the data. we will not have units and aggregation in this case.
Hope this helps.

Distinguishing between empty string and null values

hi all,
I am using an ODBC connection to connect my java app to database using JDBCODBC driver. I have 2 columns 'aColumn' and 'bColumn' in my table, both allow null values. I have one row in it, which has null value in aColumn and empty string in bColumn. I retrieve this row's data and assign it to 2 columns : 'aColumnVar' and 'bColumnVar' respectively. I find out that both 'aColumnVar' and 'bColumnVar' variables has null values (although bColumnVar should has an empty string as its value). Now my ODBC connection Data Source has the option "Use ANSI nulls, paddings, and warnings" ON. I turn it off and try again. This time both 'aColumnVar' and 'bColumnVar' variables has empty string as values (although aColumnVar should has null as its value).
How can I make sure that i can get the data exactly as it is in the database in my variables?
Thanks

there is a wasNull() method on ResultSet. After you
have obtained the value of a column e.g. by calling a
method like getString you can call wasNull and if it
returns true then the value on the database is null.
Check the java docs, it might explain it better
http://java.sun.com/j2se/1.4.1/docs/api/java/sql/Result
et.html#wasNull()I am using MS SQL Server 7.0 under Windows NT 4.0 with JDK 1.2. My ODBC connection Data Source has to have the option "Use ANSI nulls, paddings, and warnings" ON.
I try the wasNull() method but it is doing the same thing i.e. telling me that a column is null when in database it is null (right); and a column is null when in database it is an empty string (wrong). I suspect it is something to do with the JDBC-ODBC driver I am using.

Reading Numeric UDF null value in DI

We have a UDF of Numeric(4) that can be NULL, 0, 1, 2, etc. We try to read it from DI, and if it is NULL, then set the result to be -1 (the default value we difined), so we can differentiate NULL and 0.
The C# code we have look like this:
int LineNumber = -1;
SAPbobsCOM.Company oCompany;
// Code to get Company
SAPbobsCOM.Documents oDoc = oCompany.GetBusinessObject(BoObjectTypes.oQuotations);
oDoc.GetByKey(100); // Get the document by DocEntry
LineNumber = (int)oDoc.UserFields.Fields.Item("U_XX_LN").Value;
The problem is LineNumber gets 0 even if in the database U_XX_LN is NULL. We tried the code below and got the same result because oDoc.UserFields.Fields.Item("U_XX_LN").Value.ToString() always return '0' if it is NULL.
if (string.IsNullOrEmpty(oDoc.UserFields.Fields.Item("U_XX_LN").Value.ToString()))
LineNumber = -1;
else
LineNumber = (int)oDoc.UserFields.Fields.Item("U_XX_LN").Value;
The question is: how can we set it to default -1 if in the database the value is NULL?
Thank you,
Grace

Hi Grace,
Unfortunately the DI API automatically converts database null values to a default value for the datatype (eg null for numeric becomes 0 and null for strings is an empty string). If you want to differentiate between null and zero you will need to query the table using the isnull command rather than reading the table through the UserTables object:
oRecordSet.DoQuery("select isnull(U_XX_LN, -1) as U_XX_LN from [@MYTABLE] where Code = 'MYCODE')
This will convert the null value to a -1 in the recordset so you can tell the difference between nulls and zeros.
Kind Regards,
Owen

Null value handling in LOVs

Has null value handling improved any in HTMLDB 1.6?
If my LOV has "Display null"=Yes (default null value is %null%) and I need to pass in a database NULL to a After Submit process, I need to do add a After Submit computation for each of these LOVs with something like
CASE WHEN :P1_ITEM='%null%' THEN NULL ELSE :P1_ITEM END
I have a couple dozen LOVs on a page and it is getting tiring to go and do this on each and every one!
Is there a better way?
Thanks

Hi Patrick,
we are currently moving over to Apex 4.02 and are doing some smoke tests on our existing apps.
I have come across an issue with your generic solution to the %null% issue above (incidently, for a long time it's the first piece of code I include when I start a new app... thank you!)
We found that a lot of our SQL Query (PL/SQL function body returning SQL query) reports were failing due to the session state of the LOVs still having a session state of %null% even after the RemoveNulls application process had run.
After debugging your generic process we found that the LOV_NULL_VALUE in the APEX_APPLICATION_PAGE_ITEMS view has changed from NULL to '%null%'.
so the fix was as below:-
BEGIN
    FOR rItem IN
      ( SELECT ITEM_NAME
          FROM APEX_APPLICATION_PAGE_ITEMS
         WHERE APPLICATION_ID   = TO_NUMBER(:APP_ID)
           AND PAGE_ID          IN (TO_NUMBER(:APP_PAGE_ID), 0)
           AND LOV_DISPLAY_NULL = 'Yes'
           AND LOV_DEFINITION   IS NOT NULL
-- change here
           AND LOV_NULL_VALUE = '%null' || '%'
    LOOP
        IF V(rItem.ITEM_NAME) = '%null' || '%'
        THEN
            Apex_Util.set_session_state(rItem.ITEM_NAME, NULL);
        END IF;
    END LOOP;
END;Cheers,
Gus.. (always a fan of your work!)

Null Values from a Data Source

This is more of an implementation question than a
troubleshooting question. Also, since I've been unable to find any
documentation on this I was wondering if anyone has come across
this behavior or found a bug with it.
Yesterday I was working on an application to explore some
proof of concept aspects of Flex for an application I'm developing.
I started running into a problem with Flex Data Services throwing
back an 'Unknown Property: "clientaddress1"' error whenever I tried
to update data. It seemed that whenever I tried to update a record
in the database it would thrown the Unknown Property error. I spent
a good chunk of the day trying to figure out what was causing this
and finally gave up and called it a day.
This morning I was reassessing what the problem was and
trying to find the differences between my database and my code and
I stumbled upon the fact that I could add no records and modify
them without a problem, however if I tried to access an existing
record and update it I'd get the Unknown Property error.
I start analyzing the database and found that I'd configured
the database to use null values for empty values and the records
that I created with the database had null values, however, any of
the values inserted from Flex were inserted as blank values. As
matching my action script class as clientaddress1 = ""; So, upon
further testing I fould that Flex was not processing the null
values correctly, so that when it came back and rightly generated a
Conflict Error...and then called AcceptServer() it was unable to
find the clientaddress1 property of the class.
Also, if any of the properties in the database are null it
throws the same error. Basically it seems to have invalidated the
object just because one value was null. So if all of my values from
the DB are set to something and only one field is set to null it's
still throwing the error on the first alphabetical item of the
properties.
I can resolve the problem by not using null values in the
database, but...what sort of effect would this have on someone
working with a large legacy database that extensively uses nulls
for undefined values?
Also, if a Flex guru could explain the reasoning for this
happening I would greatly appreciate it!
Best regards,
Chris Maloney

I realize that I didn't clarify that I am using ColdFusion
for getting the data. This class was generated by the Create CFC
wizard in Flex Builder.

Null values in Numeric fields of Datasets

I am wondering if anyone has run into this problem before and
checking to see if anyone has an elegant solution.
I have a rather large data set. (actually 5 of them on a
single page) I am sorting certain columns in a table as numbers so
i assign the variable " ds1.setColumnType("somenumbercolumn",
"number")" In most cases Spry works great and it sorts by numbers
properly. The problem is some of the fields in the XML file are
null and I am trying to sort them as a number. Spry actually
adjusts for this (as far as i can tell) and treats them like a 0
which isn't exactly ideal considering there are real zero values in
the data. I know spry doesn't currently format numbers:
So here is my question. Does anyone one have a solution to
fixing null values in a table so that it is still sortable but
doesn't display a "0" and instead displays something like "--" or
whatever. I have the option of editing the XML file as well, but I
still need the table to sort by number.
If not null values, how about non numeric fields which can
still be sorted in a numeric column?

Hi,
We have an old post that raised a similar problem with yours.
The post can be found
here
For you situation, you should add an if condition for the
rows that have 0 and to add a custom string instead 0.
for (var i = 0; i < numRows; i++)
if(rows
[ "field_name"] == 0)
rows[ "field_name" ] = '--';
Hope this helps you,
Diana

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.

About xml and null values in 10g

Hi, I have an UCM GetFile webservice component wich receives 4 arguments, two of them are null values (rendition and extraPops), and the xml request generated by obpm is:
<GetFileByName xmlns="http://www.stellent.com/GetFile/">
<dDocName>V_123410</dDocName>
<revisionSelectionMethod>latestReleased</revisionSelectionMethod>
<rendition/>
<extraProps/>
</GetFileByName>The problem is: On UCM web service, an empty tag like <rendition/> is treated like a "empty string" value, instead of a null value, and then the response i get isn't the expected.
What I want do to is change this behavior, and when I put null values in requests, the obpm should not write those tags. Is that possible?
Should be like that:
<GetFileByName xmlns="http://www.stellent.com/GetFile/">
<dDocName>V_123410</dDocName>
<revisionSelectionMethod>latestReleased</revisionSelectionMethod>
</GetFileByName>Thanks!

Hi,
I have question regarding aggregates. It's possible to read data from BW aggregates? We have webi reports on a SAP BW multi cube and we would like to optimize retriving query.
>> Because you are using the BW Query as the source all the items that you have done so far in terms of aggregation, indexing, ... is all valid and there are no specific steps required to leverage it with Web Intelligence. Make sure the aggregates are "correct" meansing that they do reflect what you are asking for in the Web Intelligence query panel
How can we filter in webi query null (#) values. If we create condition that some variabe is diffrent from # we still get null (#) values in report.
>> You should be able to create a variable. in case you tried that already could you be more specific ?
thanks

Null value for int and datetime date type in xml schema

hi:
I am embarrassed by a qustion in xml schema; i defined a xml schema file like
this:
<elementFormDefault="qualified" attributeFormDefault="qualified">
<xs:element name="test">
<xs:annotation>
<xs:documentation>Comment describing your root element</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="password" type="xs:string" nillable="true"/>
<xs:element name="user" type="xs:int" nillable="true"/>
<xs:element name="s_time" type="xs:dateTime"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
and I send this file to workflow clientrequest() node, I wanted to receive data
in this schema file.but when i send null value to the element "user" and "s_time"
in workshop test tool(test soap),and use function in xmlbean like isNilUser or
isNilStime, one error occur.
I don't kown why, I had to ask the engineer of bea in china, one told me a bug.
is that true?

Visakh16 I cant agree more with you on it, it is good but in production u cant have them change maxrows. I think
Patrick Hurst is a better option. debug the package have it running and move up
Please mark as helpful and propose as answer if you find this as correct!!! Thanks,Dia Agha .
Hmm..Why do you need to change it in production?
What I suggested was to tweak the setting in dev machine so that it interprets the Excel file datatypes correctly when doing development. Once mapping is set correctly then it will work fine when in production or in any other environment. The tweaking is
just to make sure it interprets the datatype correctly at design time and has nothing to do with production deployment
