Validations: Null value for LOVs

See http://htmldb.oracle.com/pls/otn/f?p=24317:239
I have a "Item is not null" validation on that LOV item. The item has "Display null value" set to Yes and a LOV of STATIC2:1,2,3
If I leave the Null return value for the item to blank, the engine defaults it to %null% and the validation "knows" that this is really the same as a null value and so it kicks in (good).
But if I change the Null return value to something like %, the validation doesn't complain, it thinks that this is a not-null value.
Why the inconsistency? Does this mean that we are expected to use the default value of the Null return value i.e. leave it blank and let the engine put in %null%?
Comments? Thanks

Vikas - The declarative not null validation types recognize "actual" null or %null% as null values. This equivalence holds in numerous other situtations during page processing. Why does %null% get special treatment? A convention was chosen and that's it. And it works for almost everybody in almost all situations. In other words, it's useful, if not perfect. If you want a different value, you can specify one in the LOV (as you described). Then you can recognize and convert these values to null or %null% in an after-submit computation so that validations and other mechanisms work normally. (Perhaps it would help if the Builder created such a computation for items having LOVs with specified null values.) One use case for using a specified null return value might be where you want to distinguish a POSTed "actual" null value from the selected "null" value for which you have specified a null return value. Then you can tell if the value was selected from the LOV or whether it got a null value from the item's cache or source methods.

Pro*C & SQLDA with NULL value for predicate column

Hi: I am using a C program to update a table via a dynamic sql (method 4) and SQLDA. In the update statement predicate, I have place holders (as in TBLCOL=:C000). One of the columns in the predicate contains null values, so I set L[n] = 0, V[n] = pData (which pData[0] = '\0'), *(I[n]) = -1, and T[n] = 5 (for text). I cannot find the row that I know is there.
I cannot change my statement to contain TBLCOL IS NULL, since I don't know ahead of time if I'm looking for rows with null values for this column. The Pro*C manual says that by setting the appropriate *(I[n]) = -1, it indicates to Oracle to simulate the "IS NULL" clause, and update the appropriate rows. In my case, I receive 1403 as SQLCODE when I use TBLCOL=:C000 vs TBLCOL IS NULL. What am I doing wrong? Thank you for your help.

You should include these columns as well;
ChangeType (see mxi_changetype)
ValOwner (repository)
UserID ("jobid=<>", usermskey, GUI (mmc), DG (dyngrp), reconcile)
IdAudit (This is the event task (add and del member for assignments)
ParentAuditId (AuditID of parent which last updated the attribute, not consistent)
ChangedBy (Holds the MSKEY of the user which last changed the attribute)
ExpiryTime
to make sure you get a fuller picture of the audit record.

How do I set a NULL value for the parameter field

Hi
I've another question. I'm going to set single values for parameter fields.
// e.g. set today for StartDate parameter field
fc.setCurrentValue("", "StartDate", new Date());
It should be possible to set a NULL value for date parameter fields.
fc.setCurrentValue("", "StartDate", (Date)null);
But this do not work. How do I set a NULL value correctly?
Thank you in advance.
Best regards,
Thomas

First question - is it a stored procedure parameter?
You can't set a regular parameter field value to a null value.
There was an issue with old version of the JRC, where it was allowing null to go through, but had unexpected behavior at times.

Ted Ueda

Using Convert to handle NULL values for empty Strings ""

After having had the problem with null values not being returned as nulls and reading some suggestion solution I added a converter to my application.
<converter>
    <converter-id>NullStringConverter</converter-id>
    <converter-for-class>java.lang.String</converter-for-class>
    <converter-class>com.j2anywhere.addressbookserver.web.NullStringConverter</converter-class>
</converter>
...I then implemented it as follows:
public String getAsString(FacesContext context, UIComponent component, Object object)
    System.out.println("Converting to String : "+object);
    if (object == null)
      System.out.println("READING null");
      return "NULL";
    else
      if (((String)object).equals(""))
        System.out.println("READING null (Second Check)");
        return null;
      else
        return object.toString();
public Object getAsObject(FacesContext context, UIComponent component, String value)
    System.out.println("Converting to Object: "+value+"-"+value.trim().length());
    if (value.trim().length()==0 || value.equals("NULL"))
      System.out.println("WRITING null");
      return null;
    else
      return value.toUpperCase();
...I can see that it is converting my values, however the object to which the inputText fields are bound are still set to empty strings ""
<h:inputText size="50" value="#{addressBookController.contactDetails.information}" converter="NullStringConverter"/>Also when reading the object values any nulls are already converted to empty strings before ariving at the converter. It seems that there is a default converter handling string values.
How can I resolve this problem as set nulls when the input value is an empty string other then checking every string in my class individually. I would really hate to pollute my object model with empty string tests.
Thanks in advance
Edited by: j2anywhere.com on Oct 19, 2008 9:06 AM

I changed my converter as suggested :
public Object getAsObject(FacesContext context, UIComponent component, String value)
    if (value == null || value.trim().length() == 0)
      if (component instanceof EditableValueHolder)
        System.out.println("SUBMITTED VALUE SET TO NULL");
        ((EditableValueHolder) component).setSubmittedValue(null);
      else
        System.out.println("COMPONENT :"+component.getClass().getName());
      System.out.println("Converting to Object: " + value + "< to " + null);
      return null;
    System.out.println("Converting to Object: " + value + "< to " + value);
    return value;
}which produces the following output :
SUBMITTED VALUE SET TO NULL
Converting to Object: < to null
Info : The INFO line however comes from my controller object where I print out the set value :
package com.simple;
import java.util.ArrayList;
import java.util.List;
public class Controller
private String information;
/** Creates a new instance of Controller */
public Controller()
    System.out.println("Createing Controller");
    information = "Constructed";
public String process()
    System.out.println("Info : "+getInformation());
    return "processed";
public String reset()
    setInformation("Re-Constructed");
    System.out.println("Info : "+getInformation());
    return "processed";
public String setNull()
    setInformation(null);
    System.out.println("Info : "+getInformation());
    return "processed";
public String getInformation()
    return information;
public void setInformation(String information)
    this.information = information;

How to restrict the Null Values for Key Figules in the Bex Query

Hi Friends,
    I want to restrict the Null values of a perticular key figure in the Bex Query Output.
I will explain in details. i have 3 key figures in my query.. let us assume.. key1 key2key3
key1           key2                key3
4                4                   100.00
5                0                   200.00
1                0                    19.00
0                1                    10.00
i don't want to see the the records for which key 2 is 0.
we have a setting in the Bex Query for restricting the Zero values in the query properties. If we enable that setting it will show
4               4          100.00
but i want the report to display..
4               4           100.00
0               1           10.00
can any body guide me. <b>i want to display the values if key2 <> 0.</b>

Hi AVR,
nice to see reply.
can you eloborate your view...how can i put the condition.
<b>i want to put the condition key2 <> 0.</b>

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.

Getting null value for inputfile component in the popup

Hi,
My requirement is when i select the selectBooleanCheckBox a popup has to be rendered and with in that popup i have to display the inputfile component when i browse it should read the appropriate file.
But i am getting null from the input file component.
I written the code like this:-
1.First i have written a value change listener for the selectBoolenCheckBox.
2.I am rendering the popup from the valueChageEvent.
3.And i written the dialogListener for the Dialog in the popup.
and the code for the Dilog listener is:--
public void readingInputFile(DialogEvent dialogEvent) {
inputFile1.getValue();
//it is giving null value.
thanks in advance.
From
Srikanth.V

thanks for giving suggestion.
but i am not able to understand what meant by multipart in dialog page.
Actually,The code i written was:--
1. for selectBooleanCheckBox i written value chage listener
onChangeValue(ValueChageEvent valueChageEvent){
// in this i call the method to raise popup;
risePopUp();
2.The popup structure has follows:-
af:form --> af:popup ---> af:dialog --->af:inputfile
for this dialog i have written dilogListener:
getInputFile(DialogEvent dialogEvent){
//giving null for the inputFile,getValue();
for this dialog i don't have any multipart property

CFQUERY results return a null value for a varchar(MAX) field in SQL

I'm using ColdFusion 9 and SQL Server 2008.
One the fields in a table is defined as a varchar(MAX). Other fields in the table are ints, varchar(8000) varchar(256), etc.
When doing a query for records in the table and displaying the results using the cfdump tag, I see values in all fields in a row EXCEPT for the data in the varchar(MAX) field. The varchar(MAX) field shows a null value. Yet, I can verify through the SQL interface or through Microsoft Access querying the database that the varchar(MAX) fields have data.
How can I retrieve data from this field type?
Thanks in advance for your help.

I'm wrong. I AM getting query results, but not what I expect. I had maxrows set as a variable in my original query, so when it returned 5 rows, the first row always showed as [empty string]. I've tried numerous queries now (where UID >100, where UID >200, where UID> 300, etc.) When I use <CFDUMP> to return the query, the first records always shows empty strings.
Here's an example of some records retrieved from this simple query:
<CFQUERY NAME="BuildBack" DATASOURCE="STORBASE">
SELECT *
FROM CallUnit
WHERE CCU_ID>172

Delete after trigger returns a NULL value for the old primary key??

I am creat an After trigger that I was using to delete a row from another table. However, the OLD value returned for my primary key is a NULL value. I have an UPDATE and an INSERT portion to this same trigger that work fine with just grabbing NEW values, but this OLD value cannot be grabbed for some reason, although it seems to work on other tables when the owner is me, the problem table is not owned by me though. Has anyone run into this before? Is there a view that I need access to from this table or perhaps a setting I need to turn on? I am at a loss. Thanks.

Cannot reproduce with this modified trigger code â¦ right now I believe the problem is in this part:
BEGIN
col_ret := vpack.vOPCollectIO(tpid, User, 'SCOTT.OINFTABL', dmltype, vdata);
EXCEPTION
WHEN lost_connection OR lost_connection2 THEN
    col_ret := vpack.vOPCollectIO(tpid, User, 'SCOTT.OINFTABL', dmltype, vdata);
END;
In schema CORE:
SQL> create table oinftabl
2 ( akey     number(9) primary key
3   ,astring varchar2(10)
4   ,astring2 varchar2(10)
5 );
Table created.
SQL>
SQL> grant all on oinftabl to flip;
In schema FLIP (which has âCREATE ANY TRIGGERâ):
flip@FLOP> CREATE OR REPLACE TYPE VDAT AS VARRAY(100000) OF VARCHAR2(50);
2     /
create or replace trigger sbt3_system_oinftabl_x
after insert or update or delete on core.oinftabl
REFERENCING NEW as n OLD as o
FOR EACH ROW
DECLARE
col_ret INT;
dmltype CHAR(1);
tpid VARCHAR2(30);
vdata VDAT; --varray datatype I created;
lost_connection EXCEPTION;
lost_connection2 EXCEPTION;
already_there EXCEPTION;
PRAGMA EXCEPTION_INIT(lost_connection, -28576);
PRAGMA EXCEPTION_INIT(lost_connection2, -28579);
PRAGMA EXCEPTION_INIT(already_there,-1);
BEGIN
tpid := SYS.DBMS_TRANSACTION.LOCAL_TRANSACTION_ID();
IF INSERTING THEN dmltype := 'I';
ELSIF UPDATING THEN dmltype := 'U';
ELSE dmltype := 'D';
END IF;
IF INSERTING OR UPDATING THEN
    dbms_output.put_line('new akey='||nvl(to_char(:n.akey),'null'));
    dbms_output.put_line('new astring='||:n.astring);
    vdata := VDAT(
    to_char(:n.AKEY),
    :n.ASTRING,
    :n.ASTRING2,
    NULL);
ELSIF DELETING THEN
    dbms_output.put_line('old akey='||nvl(to_char(:o.akey),'null'));
    vdata := VDAT(
      to_char(:o.AKEY),
      NULL);
END IF;
for i in 1..vdata.count
loop
    dbms_output.put_line('vdata('||i||')='||nvl(vdata(i),'null'));
end loop;
--BEGIN
-- col_ret := vpack.vOPCollectIO(tpid, User, 'SCOTT.OINFTABL', dmltype, vdata);
--EXCEPTION
-- WHEN lost_connection OR lost_connection2 THEN
--    col_ret := vpack.vOPCollectIO(tpid, User, 'SCOTT.OINFTABL', dmltype, vdata);
--END;
END;
Trigger created.
flip@FLOP> show errors
No errors.
flip@FLOP> insert into core.oinftabl values (1,'abc',null);
new akey=1
new astring=abc
vdata(1)=1
vdata(2)=abc
vdata(3)=null
vdata(4)=null
1 row created.
flip@FLOP> update core.oinftabl set akey=2, astring='cba' where akey=1;
new akey=2
new astring=cba
vdata(1)=2
vdata(2)=cba
vdata(3)=null
vdata(4)=null
1 row updated.
flip@FLOP> delete from core.oinftabl where akey=2;
old akey=2
vdata(1)=2
vdata(2)=null
1 row deleted.
So the trigger has the OLD AKEY value when DELETING and it does successfully store it in the VARRAY.
Hence the problem is in that pl/sql block at the end.
What are you doing in there?

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

thanking you
sridahr

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.

SQL Loader Null Value for Date

Dear buddies,
This is how my date column is in my control file.
dtEdu timestamp(6) with local time zone "YYYY-MM-DD HH24:MI:SS" "nvl (to_date (:dtEdu, 'YYYY-MM-DD HH24:MI:SS'), to_date ('1982-03-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))", The problem is some of the columns in dtEdu has NULL values and I couldn't load them.
So, trying to replace it with something else.
Could someone help me?
Thanks a lot.
Nith

I don't know how your so called "NULL" values look like, but if the null data is actually made up of blanks, try adding LTRIM() around :dtEdu.

Problem setting initial value for LOV

Hello, everyone. This seems like it should be simple, but it's giving me lots of problems. I am trying to create my first LOV. I have a messageLovInput item called PFedFilingStatus. From the Property Inspector, I can set an Initial Value of "02", which displays when I run the page, and lets me change it and validate it using the associated LOV.
What I would rather do is set the initial value programmatically, but here are my problems:
If I set the value like this:
OAMessageLovInputBean lovText = (OAMessageLovInputBean)pageLayout.findIndexedChildRecursive("PFedFilingStatus");
lovText.setText("02");
then the field displays properly at run time, but can't be changed. The LOV runs, but any value I select flips back to "02"
If I set the value like this:
lovText.setDefaultValue("02");
then nothing seems to happen at run time. The value is not displayed at all.
Can anyone tell me what I am doing wrong? Thanks for your help.
--Dave

Yes, that helps a bunch. Now can you tell me where that is set?
Thanks so much.

NULL value in LOV not displaying in Viewer as NULL

Discoverer Viewer: 10.1.2.54.25 CP4
I have a list of values ('A','B','C',NULL).
In desktop the drop down shows
A
B
C
NULL
However in viewer I get
A
B
C
When I select the area just under C, which I presume to be NULL, it allows me to move it over. However when I'm ready to run the query, it informs me that I have not selected a value. I can manually key in NULL and the query will execute without a hitch.
What am I doing wrong?
Thanks,
Jamie

I'm not sure I understand exactly what you need.
But your LOV show the DNAME and return the DEPTNO, so of course the LOV will return the DEPTNO even if the DNAME is null.
To return null if the DNAME is null, indeed you can use decode but in the return value :
select dname d, decode(dname,null,null,deptno) r
from test_dept
order by 1

Validations: Null value for LOVs
