How to handle Null value in Database Adapter

I configured the DA Adapter, with operation type as "Perform an Operation on a Table - Select" and added few where clause parameters (StreetNo, StreetName city, country, state, zipcode)too.
If we won't enter any value for any of the column in the table (S_ADDR_PER) is taking as NULL, so what happening is, if i give "%" or if i leave as "blank" to those columns(input for where clause parameter). The DB adapter not fetching any records. Any help to handle this situation.
I need query like this...
select * from S_ADDR_PER where city like '%' AND state is NULL AND addr_line_2 like '%';
seems.... I can't use the pure SQL option since i don't know which column will be null. Some case the addr_line_2 column will be NULL in table, in some other case the state or city column will be null.

Hi,
you can handle null with date like this , If it doesn't wortk for you then please explain your problem.
select NVL(to_char(sysdate,'DD-MON-YY'),'Not Recorded')
from dual
NVL(TO_CHAR(
08-NOV-05
select NVL(to_char(NULL,'DD-MON-YY'),'Not Recorded')
from dual
SQL> /
NVL(TO_CHAR(
Not Recorded

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

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

How to handle null values in RTF templates

Hi - I have two groups in a report for different SQL and two formulas for each group, CF_ELE_CNT and CF_ELE_CNT1. In the template I use the below code to print or not print a section.
<?if:number(CF_ELE_CNT +CF_ELE_CNT1) >0?>
The problem is when there is no data in the second group its not creating the XML tag for CF_ELE_CNT1, though CF_ELE_CNT has 13, it still does not print that partucular section. If I remove CF_ELE_CNT1 from the condition it works fine. I was wondering how to handle this.
Any help would be appreciated!!
Thanks,
Rav

Hey Rav,
You can add a check to identify it the element/tag is present or not
<?if:(CF_ELE_CNT1)?> will give true, if the element is present otherwise falsesince you are adding the two elements, you have to add a or condition.
<?if:(CF_ELE_CNT and number(CF_ELE_CNT) >0 ) or ( CF_ELE_CNT1 and CF_ELE_CNT1 >0)?>

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

Hi,
Null value in database displaying as 0 in report, I need to keep value as in database, and I have one calculated row which is based on null values should also null in report.

my report is like
col1 col2
ABC 0

List of values from Database Adapter - BPM Forms

Hi all,
Can anyone tell me how to get list of values from Database adapter and a ServiceTask.
As example lets say a table has Employee and Department columns.
I want to list down all the Employees in BPM form (Select One List Box) once i provide the department to the Database Adapter.
Is it possible from the DB Adapter?? What will be the variable type?
Thanks,
Nir

Hi DanielAtwood,
Thanks for your reply...
Actually when i send the variable in 'WHERE Clause' in Db Adapter query it will retrieve more than one record as the output.
I want to put that values to a 'SelectOneChoice' component and list down all the values..
First I tried with data control. But i couldn't find the way to pass the value to the variable(in WHERE clause) to the query in data control view.
Thanks,
Nir

Model of how APEX handles data (values)?

Reference {thread:id=2486655}
I'm trying to get a model of how APEX handles data (values). There are several places(?) that data (values) can exist. Or so it seems. I'm trying to understand how these work -- to put all the pieces together.
Question:
A) Where data can be?
1) In the database
2) In the session
3) Rendered -- and hence displayed on the screen, if a displayed value -- but not in the session
4) In perhaps(?) some working memory pool(?) but different from the page rendered values I see on the screen?
5) Other?
Why do I think this is relevant?
Question:
B) If there are rendered values and session values different from the rendered values, then when code executes, which of these values (rendered or session) is it executing against?
And maybe the answer is, "You don't understand what's going on." Yes, "Exactly!" Hence the question.
Best wishes,
Howard

Howard (DBA in Training) wrote:
I'm putting this together now. For example:
I set the value of a Page Item (say, :P2_DATA) to "BEFORE" in a Before Region process and change it to "AFTER" in an After Region Process. 'BEFORE' was displayed on the screen but 'AFTER' was in the session state. So I see that PL/SQL changes these values in the session state. But it doesn't "go back" to change the HTML after the region has been rendered -- hence we see BEFORE shown on the screen. (I'll have to think about what a Dynamic Action does.)
Also, if a page item has a default value, say 'DEFAULT' then that value doesn't get into the session state. At least, not with my current settings. Oh, that explains a lot of confusion!! I suppose there's a logical reason for this but who would expect default values to be differently from other PL/SQL operations on the item?
Questions:
1) So why does a default value not get put into the session state?Several reasons, among them:
*1. When/why is the value required?* Region items (and thus their source and default values) are rendered in region/item sequence order. The item's source/default value would therefore not be available in session state until it's rendering point. This is frequently later in page show processing than the value is actually required, such as the common use case of including a data value in the page or region title. Setting the value in a Before Header/Regions computation or process makes it available as required before the item is actually rendered.
*2. The rendered page might not be submitted.* Default values are typically set when a page will create a new row. Consider the situation where the user clicks a "Create" button and is presented with an order entry form containing several default values. They then decide they don't want to create a new order after all, and navigate away from the form page via some mechanism that uses a redirect rather than a submit (such as a default "Cancel" button). This means that no page submit processing is performed, and generally that no session state management is performed. If the default values were set in session state, the order entry page would contain the default values for the non-existent order despite the user never submitting it. This may have unwanted side-effects if these values are referenced elsewhere in the application, and therefore would require extra session state management to be built into the application.
*3. A rendered item might not be submitted with the page.* Per the HTML specification, the values of disabled controls unchecked checkboxes are not POSTed on page submit. Consider a situation where a checkbox item is set with several default values, but the application requires that the checkboxes be cleared and disabled by a dynamic action if the user chooses certain options from a select list. In this case, on page submission no values are submitted into session state for the checkbox item. If the defaults had been set in session state, then the application would be in an inconsistent state, with the user-selected option indicating that none of the checkboxes were checked, but with session state holding values showing that they were. This would require additional processing to ensure that the application's state was consistent before saving it to the database.<sup>1</sup>
2 & 3 are particularly significant in basic wizard-generated applications. Doing things in this way, the wizard-generated DML and navigation "just works", without the need for additional session state management.
2) Is there a Page Item setting that causes the default value to be saved to the session state?No. Hopefully the explanations above provide sufficient reason to show why this is genearlly not desirable. On the rare occasions when it is required, set the session state value using a computation or process.
<sup>1</sup> There are other reasons—mainly security related—that make it good practice to perform such checks in more complex and internet-facing applications anyway.

HELP NEEDED !! Null values in Database

Hi there !!
I need help with EJB 3.0 passing null values to database. The situation looks like that :
I have created EJB entity class called "Osoba.java", it is in relation
with "Rola.java" (one to many). Each Object of class Osoba can have
many Roles. Then I created "OsobaServiceBean.java " I included it with
metod "CreateUnregisteredOsoba(Osoba , Boolean)". From "flex" level I
call this bean - call is accepted, and as a result new object of class Osoba is added to database. Problem is that only one column is filled in table,

The row numer 1 is added by hand and it works. row number 33 and 32
are added to database by method CreateUnregisteredOsoba. As you can
see fields login as well as Roles and RoleGroup are empty (NULL). What
Im doing wrong ?
Thanks for your help -
Roman Kliś
PS. Table Osoba works fine - everything is added as I want.

I solved problem.
The reason why EJB had not added anything to database NULL was becouse wrong names of class. Ive refactored whole class Rola.java to RolaClass.java and suddenly it worked.
True reason is still unknown but most importent is that it works.
Thanx for reading topic - hope next time someone will answer my questions.

How to handle empty file using sftp adapter

Hi,
Please explain me how to handle empty files in sftp adapter.
Thanks,
Enivass

Hi Enivaas,
I don't have the seeburger sftp adapter at hand at the moment, but asfar as I remember, this does not specifically have an empty-file handling option like the standard ftp adapter.
So to stop emtyp files from being written, guess would need to handle this at the mapping level. For example, check for target creation criteria in the header node in mapping. If the creation criteria is not met, you can throw an error in mapping.
You may also incorporate this condition in your Receiver determination. In this case, if the condition is not satisfied, no receiver is determined in PI.

Handle NULL Values from Teradata Database in OBIEE

Hi All,
I have records in a Teradata that are marked with 'A' for Available and sometimes blanks. Even though in OBIEE I have put a filter that says display all records with NULL values or 'A' I am only getting values with 'A'. How can I pick up the records with blanks in that field.

Looks like the column value is not NULL. I would suggest to know the exact value of the column
you may go for expression like length(col) where col!='A'
or
case when col is null then '1null'
when col='' then '2'
etc..
once you know the value then replace with 'Unspecified' or any text.
