JDO: How to determine NULL-values

Hi all,
I'm using JDO to access a database-table. One of its attributes is of Oracle-type NUMBER and mapped to Java-type int. The attribute can contain the values 0, 1, 2, 3, 4 and NULL. How can I distinguish between numeric 0 and DB-value NULL? When I read the attribute via JDO the member-variable gets the int-value 0 in each case, of course!
Thanks for each hint,
Christoph

not too sure what you mean, perhaps you could supply a table description and some sample data
but, consider
delete from table_1 where column_1 is null

How to Replace Null Value as 0 in an OBIEE11g Pivot Table? it's working 10g

Hi,
How to Replace Null Value as 0 in an OBIEE11g Pivot Table? it's working in obiee10g version.
We have tried below methods
1) criteria tab and edit the ‘column properties’ associated with your fact measure. Choose the ‘Data Format’ tab, tick to override the default format and choose ‘Custom’.
It seems that the syntax for this custom format is positive-value-mask (semi colon) negative-value-mask (semi colon) null-mask. So this means we have a few options.
E.g. if you want zeros (0) instead of null then enter:
#,##0;-#,##0;0
2) in that formula columns we have put it below case condition also ,
Measure Column: Nom_amt --> edit formulas
CASE WHEN Nom_amt IS NULL THEN 0 ELSE Nom_amt END
3) we have uncheked IS NULL check box in the admin tool also
I tried above formats still it's not working for me..kindly help me on this..
thanks to do the needfull

How to determine the value of -D__SUNPRO_CC?

Could any body tell me how to determine the value of -D__SUNPRO_CC? Iam now using Sun Studio 9.
Thanks in advance.

The C++ Users Guide describes all the predefined macros set by the compiler.
The __SUNPRO_CC macro is a 3-digit hex number. The first digit is the C++ compiler major version number, which is 5 for all releases from WorkShop 5 in 1998 through the current release, Sun Studio 10. The second digit is the minor version number, increasing by 1 for each release in the major release series. The 3rd digit is a place holder for the very rare (none since 1994) cases when we have a micro version number. It is zero in current releases.
The current compiler release is C++ 5.7, so __SUNPRO_CC is set to 0x570.
You can see the macro setting by running
CC -dryrun -c foo.cc
and look for the -D__SUNPRO_CC =0xNNN on the ccfe command line.

How to assign NULL value to an ITEM in Forms Personalization?

How to post null values from h:inputText?

Hello,
I have a form made of h:inputText fields that map to an entity class as the backing bean. Whenever I post the form from a web page, all the fields that I did not fill out and that are mapped to String fields in the entity class are set to "" (empty string) instead of null.
However, I would like to post null values to my entity, because that would indicate that the user did not fill out the field. In other contexts (outside of the web app) it is possible to set the fields to empty strings, but from the web app it should always be null. How can I get JSF to do this correctly?
Also, when reading entitys with null values from the database, these are converted to empty h:inputText fields, so this direction works as expected.
Ulrich

I haven't seen a solution for this as far.
This is how I do it:
public void action() {
    if (isEmpty(inputValue)) {
        // do your thing
    } else {
        // do your thing
public static boolean isEmpty(Object value) {
    if (value == null) {
        return true;
    if (value instanceof String && ((String) value).trim().length() == 0) {
        return true;
    if (value instanceof Collection && ((Collection) value).size() == 0) {
        return true;
    // And go so on .. make it an utility method.
    return false;
}

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.
Regards,
Varun

How to populate null values as blank in cell

Hi All,
I have an query i have data like blow

1Q-4Q 2009
4,069,379
% Change
-2%
1Q-4Q 2010
3,979,490
for the 1 column i am getting 0% age due to i applied previous function but i don't have data for 2008
so i am trying not to populate 0% for the % change before 2009
I have checked with null value
If (IsNull(Previous [data])) then "" else ([data]/previous[data]) -1*100
so it is populating blanck value but i can not formatting the values as %age
please suggest
how can i solve this issue please advice
Thanks in advance
Ranjeet

Change your formula to be:
=If(IsNull(Previous([data])=0 then ([data]/previous([data])-1 * 100
You can ignore the else part and it will leave the null cell as blank and you can still use your number format.

How to determine the value of a Standard Value in a routing operation

Dear Experts,
Kindly guide me on how to detemine the value of my Standard Value in the operation of my routing, or in the phase of my Master Recipe.
I mean what determines the value that I enter for the Standard Values: Machine and Labor in the phase of my Master Recipe?

Hi,
In the Routing / Master Recipe, the standard values are based on the lot size.
For Example, if you have the lot of 100 KG, then in recipe the machine time will be 2 hr and labor time will be 2 hours, it means to make 100 KG we require 2 hrs of machine and 2 hrs of labor.
Normaaly all production manager / supervisor will have the date for the hours. The system will calculate will respect to batch / lot size.
If you have order for 1000 KG, then the system will assign 20 hrs for Machine and 20 hrs for labor.
This will be used for Capacity planning and Costing.
Capacity plan here your requirement is 20 hrs for machine and labor. If you have a reacto which wil run for 24 hrs a day, then the order will be completed in a day.
Costing is concerned, all std. valur key will be assigned with an activity type in work center / Resources and the prices for activity type / cost center will be maintained in KP26.
Based on the cost and hours, the system will allocate cost for the order (it will be planned cost). When you are confirming the order you will enter the actual time for the operation, then that will be your actual cost.
Pl do a sample test scenario in your sand box, and surely you will understand more.
The data for Routing / Recipe will be provided by the production manager of the plant and activity price will be provided by the finance team.
Thanks,
JK

Oracle Discoverer: How to handle null value

In Oracle Discoverer, I pull data from a folder. When I hit Null value for a column, I want to replace it with data from another folders column. Something like the functionality of "nvl" of a SQL statement. How can I do the following query in Discoveror :
example: select nvl(table1.column1,table2.column2) from table1, table2
where table1.column7 = table2.column7.

Hi,
You first need to include any column from folder table2 into your report so that Discoverer will do the join. (This assumes the join between table1 and table2 is set up in your EUL). Then you can create a calculation containing nvl(table1.column1,table2.column2) . You can then remove the column from folder table2 and the join will stay in your workbook.
Hope that helps,
Rod West

Thanks.How about showing us the query? If you have an outer join condition between the tables, that would account for the NULL qty in the 4 "extra" rows. In that case, you'd want to remove the outer join from the query.

How HANA handle NULL values

Hi frzz,
Can any one explain me how exactly HANA handles NULL values??
Best Regards,
Krishna.

Hi Krishna,
You can use IFNULL for the SQL queries/script instead of ISNULL . Since ISNULL is binary function and will be mostly used for the CE Functions based Calc views.
Try using the same queries with IFNULL instead of ISNULL, it should work

How to pass NULL value in SSRS

Hi All,
I have a parameter called Division,Region and State.While loading these parameter I am replacing NULL value as "NO Division","NO Region" and "NO State".Note all parameters are multi valued.
Now In my dataset query If I put the condition like (division=@Division or Division is null) and (region=@region or Region is null) and (state=@State
or State is null).
In this scenario if I want to exclude null values need only specific Division which is not allowing me to do that with above condition.If I need all it works fine but not with specifice division,region and sate.
Any thought on this.
thanks
Chandan
Thanks Chandan

Thats because of or conditions
As per your explanation since you replace NULL value as No division etc what you need to do is just this
(division=@Division or @Division = 'All') and (region=@region or @Region = 'All') and (state=@State or @State = 'All').
this will make sure it will bring all values including NULLs when you pass All and will only give you specific division/region etc records when you pass a specific value.
To get NULL valued records alone you need to pass value as No Division,No region etc
Also you should change dataset query for parameter combo to make prompt as No Division etc for NULL values so that it can be selected as an option inside multi valued combo box to see NULL valued records
