Using null value of item

Hi All,
I use this part-of-code in pl/sql statement in a 'where' clause in order to filter records to those that took place between some hours range:
..... and to_char(STARTDATE,'HH24:MI:SS') between NVL(:P3_HOURS_FROM,'00:00:00') and NVL(:P3_HOURS_TO,'23:59:59')
P3_HOURS_FROM & P3_HOURS_TO are combo box items with LOV (0:00,0:30,1:00 ....etc that returns 00:00:00,00:30:00,1:00:00 respectively). I use a null value which is displayed as '--:--'.
when i choose some hour range the rsults are correct. the problem is when i choose null values. there is no results to the report, probably (i guess) because it somehow translate the (null) time value to the same value (and it's obvious that between same time values there isn't any result).
so i guess i use 'null' value in an inappropriate way.
Can u tell me what do i do wrong???

Are you sure you are returning NULL and just displaying '--:--' in your LOV?
If the state of your LOV is becoming '--:--' then this does not equal null in PL/SQL land.
I presume you are also submitting after changing your LOVs?
You can check the state of your items by clicking the session state in the developers toolbar at the bottom. See what your items are being set and report back!

Oracle 11.1.0.7.0 Issue with Streams when using NULL value in a key field

Hi,
we have an issue in our replicated environment using Streams.
We have a replicated table using the following index:
UK_S01_TEXT_FORMAT_TBL01 SOGID
UK_S01_TEXT_FORMAT_TBL01 INDEX_TEXT_FORMAT_ID
UK_S01_TEXT_FORMAT_TBL01 INDEX_LANGUAGE_LABEL
UK_S01_TEXT_FORMAT_TBL01 INDEX_TEXT_FORMAT_COUNTER
UK_S01_TEXT_FORMAT_TBL01 INDEX_PROVIDER_ID
UK_S01_TEXT_FORMAT_TBL01 INDEX_TARIFF_PLAN_COSP_ID
with field INDEX_PROVIDER_ID allowing NULL values. Actually we insert empty strings in there, but as far as I understand Oracle will convert it sliently in a NULL value, which is fine to our application.
When we apply a change on that table (either update or delete) we get errors at streams level and the transaction is not propagated.

If I force the set of primary keys to be only the NOT NULL fields, I can successfully apply the error, but since we may have them storing both NULL and NOT NULL values, this is not a solution.
I'm wondering why the DB on one hand converts the empty string in a NULL while inserting, but it looks the Apply process onStandby is not able to do the same when looking for the record before applying the transaction.
Thanks in advance!
Cheers,
Mike

Using null values to change text boxes

Very simple question I believe.
I have a form with rows of data. All I want to do is say that if a given field in a row "description1" is not Null, then populate another field with a specified value.
jA

if (descriptionFieldName.rawValue != null){
otherFieldName.rawValue = "value you want to give it";
If there are multiple rows of this information you will have to add the row subform to the expression as well as an occurance number so it wil know which one you want . I will use i to indicate the occurance:
if (Row(i).descriptionFieldName.rawValue != null){
Row(i).otherFieldName.rawValue = "value you want tto give it";

Conditional formula using NULL values

Hi Experts,
Here's the background using Query Designer.
V1 = Formula Variable - Rep Path - converting master data attribute value into "number" (eg, attribute "status" = 02 becomes the number 2)
RKF1 = Sales for Day 1
RKF2 = Sales for Day 2
CKF1 = (V1 = 2) * RKF1
CKF2 = (V1 = 2) * RKF2
CKF3 = (CKF1 <> NULL) * (CKF2 <> NULL) * (CKF1 % CKF2)
My issue is with CKF3 where I need to void the entire formula for that row if EITHER CKF1 or CKF2 values are NULL. I know in other reporting tools they have a "IS NULL" or "IS NOT NULL" operator but I know Query Designer does not. Are there any ways around this? This is something that needs to be dynamic which is why we can't calculate this during load time. The values will differ depending on the variables assigned so the NULL solution seems to be the only way around this.

RKF1 = Sales for Day 1
RKF2 = Sales for Day 2
CKF1 = (V1 = 2) * RKF1
CKF2 = (V1 = 2) * RKF2
CKF3 = (CKF1 NULL) * (CKF2 NULL) * (CKF1 % CKF2)
In CKF3, you mean (RKF1 % RKF2) right? Other wise it doesnt make sense.
Could you please state what is required?
So - the formula is correct CKF3 = (CKF1 != NULL) * (CKF2 != NULL) * (CKF1 % (percentage share) CKF2)
So if CKF1 is null, then it makes the formula equal 0. Same thing with CKF2 - if CKF2 is NULL, then it makes the formula equal 0. Which makes 0 % 0 equal 0% which is what I want (if either CKF1 or CKF2 are null).

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.
package com.generated
[Managed]
[RemoteClass(alias="components.generated.clients.Clients")]

Webservice returns null values (Flex)

Hi all,
I created a webservice in abap,
(a RFC and a Function Web Service).
It exports a table type and contains data from a Ztable.
When i request it from Flex, it returns rows, but they contain NULL values, why ?
I can request and display bapi webservices that comes with in SapNetweaver trial 7.1 but i cant display my own webservice.
Result like this;
result     generated.webservices.ZCUSTOMERS_TT (@2205981)
     [inherited]
     [0]     generated.webservices.ZCUSTOMERS (@2362c91)

     [3]     generated.webservices.ZCUSTOMERS (@23a41c9)
it is true that there are 4 rows in table, but all client, id and name is null
why ?

thanks for answer but my problem didint solved.
My webservice can return normal values like integer or decimal and i can read it from flex.
but when i try to view tables, i always get null values BUT item count is true :=) i have 4 item in z table and 4 rows returns in array from webservice but NULL values :=).
I can't return structure as well.

What do you use, when declaring variables ?
Like or type or ref to ? Can it be a problem ?
here is my function export inteface.

NULL Value in Journal Entry and Wrong Tax Summary

Hi people,
I need your expert help for a big problem that appens to some customers.
They run SAP BO 8.8 SP:00 PL:12
This is the scenario:
You insert a new documet, A/R Invoice or A/P Invoice is the same, problem appear in all of them.
After you insert the document, using SQL Server Management try this Select statment:
Select * from JDT1 where JDT1.debit is null OR JDT1.credit is null
A list of record where listed. And, this is the problem, NULL values are all in the VAT Lines in debit or credit colums.
If you try to make a SUM(debit-credit) you discovery that, 1000,00-null=null
Consequently, TAX Sumary report, that probably use arithmetic operation like me in SELECT statment, count a wrong number when null values in DEBIT or CREDIT column in JDT1 for VAT declaration.
How could I solve? And how i can make invoices store 0 rather than NULL in the VAT Line?
Thanks in advance for your tips and solutions

Thaks Neetu for your answer.
I thinks there is a misurandertanding.
My problem is not SQL.
My problem is the SAP TAX Report.
I used SQL only for check data and discover why SAP raise a wrong TAX Summary report.
So, my question is: Why invoices write null values in journal entry, and how I can solve the problem that TAX summary report use null value in operations so the results are wrong.
Thanks,
Jonny Cortonicchi

While that is true for a unique index on columns where all values are null, it is not the case where one of the values is not null:

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).

Null Value Item

Hi all,
As per below coding in my application need to export each column data to excel. total column of my table is 10.
Normally , the 5th column usually is null value and other
column is not null.
the question is below coding can't loop 6-10th column due to 5th column is null value then break.
everybody can tell me how to cause pl/sql can loop 6-10th column even 5th column is null ?
FOR k IN 1..10
LOOP
IF NOT NAME_IN(:system.cursor_item) IS NULL THEN
args:=CLIENT_OLE2.CREATE_ARGLIST;
CLIENT_OLE2.ADD_ARG(args, j);
CLIENT_OLE2.ADD_ARG(args, k);
cell := CLIENT_OLE2.GET_OBJ_PROPERTY (worksheet, 'Cells', args);

Hi Gerd,
tks for yr remind.
i have another one question. can u help me ?
my trigger is use for export data to excel from data block. i feel it process slow too. because it is a one by one column/row insert.
how to enchance the performance from coding ?
i know that use table type in trigger for store a heap of data then insert to excel once. but i don't know how to implement. can u tell me how to do that .
tks a lot.
pls see below trigger is one by one insert.

Using null to replace values

I'm a newbie! Can you tell me how can replace existing values in a variable. My plot in the program is to have the price of products in my right hand then transfer that to the cart and then to cashier lady. I have to make sure and know that when I transfer the price from my right hand to the value cart the right hand should no value, then when from cart to the cashier the cart should have no value. The code below is not yet finish. I'm just testing it on one product. I just to know the transferring concept. Can I use null?
This my are codes:
the customer class
public class customer{
     String fullName,walletName;
     double wallet,money;
     public void sayName(){
          System.out.println(fullName + " is inside the grocery");
     public String giveFullName(){
          return fullName;
     public void sayWalletBrand(){
          System.out.println("Let me see how much money I got from my " + walletName + " wallet\n");
     public void contentWallet(double money){
          wallet = money;
     public void lookWallet(){
          System.out.println("Show that wallet has the value " + wallet);
          System.out.println();
the product class:
public class product{
     String description;
     double price,rightHand;
     public double containRightHand(){

Variables of object (class) types may be set to null, meaning they point to no object.
Variables of fundamental types (int, byte, char, long, double, float, boolean, etc.) can not be set to null. Maybe you can set your numeric types to 0 and boolean to false, to indicate nothingness.

Null values returned when using request.getParameters(

I have a html form which allows the user to choose options and select a file to upload. When I use method=Post I get null values returned. When I use method=Get I get my parameter values fine.. but I get an error.
"Posted content type isn't multipart/form-data"
I would like to know why I am getting null values returned when using Post. I am using the following to get the values from the name=value passed to the servlet.
String strIndustry = request.getParameter("frmIndustry");
String strCompany = request.getParameter("frmCompany");
String strCollabType = request.getParameter("frmCollaboration");
I have another form where the user can search information in a database that works just fine w/ either Get or Post
Or perhaps I am using oreilly MultipartRequest incorrectly??? but I copied it directly from another discussion.. ???
any thoughts
Thanks

taybon:
you could do it like this. in this case, you submit your form with the parameters (industry, company, collaboration), and upload your file at the same time. and in the target servlet, you can build your MultipartRequest object like this:
MultipartRequest multi = new MultipartRequest(request, temp_location, 50 * 1024);where variable temp_location stands for a temporatory diretory for file uploading.
and then you get your parameters, so you can build the directory with them. and after that, you can move your file to that directory using File.renameTo();
but as i've suggested in my previous posting, i just recommend you upload your file in a separate form. and then you can perform an oridianry doPost form submit with those parameters. or you may have problems with the file uploading. (this is just my personal experiences with Multipart).
there is one other thing i'd like to mention, file.renameTo() won't work if you need to move files to a network drive in windows. it won't work if you move files across file systems in unix.

After hiding an item, its value cannot be used in a query. How to use the value of a hidden item.

Hi,
I have a shuttle. I am using its value in a query by using sql collection array. My requirement is that I need to hide that shuttle. But when I hide the shuttle, its value is not retrived by the query.
Please give some idea how to get this functionality.
Thanks,
chandru

Its a shuttle. so how to create an application item of shuttle type?
pls give some idea.
You don't create an application item of shuttle type. Application items only hold one value, and I thought since you were using a value in a query that you were only using one. In the case of multiple values my idea to use a page/application item will not work

Hi,
Did u selected the option filename from the Adapter message specific atribute of file adapter.
When u run the whole scneario that time this will work if u run the scneario using test message tab of message mapping it will give null value only.
THe AMSA will work when u test it end to end.
check it out.
