Check for null value for Date Field
Hello everyone,
I have a database that consist of date field and also a bean that will able to access the db.
here are my example:-
private int setDate(int date) {
this.date = date;
private void getDate {
return date;
later, I entered a date value and wanna check whether the date is on the database or not. SO, do you all have any idea?
Perhaps before passing your date off to a primitive int, you could pass it to an [Integer] object. Then check to see if that object is null;
Integer d = new Integer(int value);
if (d == null) {
}

How does APEX check for null values in Text Fields on the forms?
Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
ThanksSee SQL report for LIKE SEARCH I have just explained how Select list return value works..

How to check for null values in bpel?? Please Help! very urgent!!!
Hello Guys,
I have a problem. I have an external webservice to which I have to post my request. My task is to create an Webservice and Service Assembly to which others would post request and get response. I have to create SA to deploy onto the bus.
The problem is that there are optional elements in the request and response xsd's. In the Response sometimes certain feilds may come or they may not. for Example:- my response could contain a tag like this <firstName></firstName>
I have to copy these feilds in my bpel process from one variable to another.(like in the mapper).
My Question is , Is there any way in BPEL process or BPEL mapper where I could Check for null values in the request or response???
Your inputs would be very helpful.
Thanks
RajeshThanks for replying man :)
Ok I will be more clear.
Here is a snippet of one of the xsd's that I am using.
<xs:element name="returnUrl" nillable="false" minOccurs="0">
<xs:annotation>
<xs:documentation>Partner specifies the return URL to which responses need to be sent to, in case of
Async message model.
</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:anyURI">
<xs:maxLength value="300"/>
<xs:whiteSpace value="collapse"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
This means that the return URL field can be there or it may not be there. But if it is there it cant be null because nillable=false. But the whole <returnURL> </returnURL> can be there or it may not be there because minOccurs=0.
My requirement is , if returnURL is there in the response with a value, then in my BPEL mapper I should map it else I should not map it.
Thats the issue.
and Yes kiran, the node be non-existant.
So can you please help me with this.
Thanks

Check for null values in conditional formatting when no rows returned.
I have a report that is showing facts for different months.
For some months there is no row in the facts table.
But in the report, I have to show a * when there is no data.
If there is a row in the facts table with null value for data, the conditional formatting successfully shows a * when data is null.
But when no row is present in the facts for a particular month , conditional formatting is unable to detect any null, as none exist.
How we can check that no rews returned for a particular month and then show *?

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,
ThomasFirst 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.

Checking for null value in arraylist
Hi
i have an excel file which i i am reading into an arraylist row by row but not necesarrily that all columns in the row mite be filled. So how do i check for null values in the array list.
try
int cellCount = 0;
int emptyRow = 0;
HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(file));
HSSFSheet sheet = workbook.getSheetAt(0);
Iterator rows = sheet.rowIterator();
myRow = new ArrayList();
int r = 1;
while (rows.hasNext())
System.out.println("Row # " + r);
HSSFRow row = (HSSFRow) rows.next();
Iterator cells = row.cellIterator();
cellCount = 0;
boolean isValid = false;
while (cells.hasNext())
HSSFCell cell = (HSSFCell) cells.next();
switch (cell.getCellType())
case HSSFCell.CELL_TYPE_NUMERIC:
double num = cell.getNumericCellValue();
DecimalFormat pattern = new DecimalFormat("###,###,###,###");
NumberFormat testNumberFormat = NumberFormat.getNumberInstance();
String mob = testNumberFormat.format(num);
Number n = null;
try
n = pattern.parse(mob);
catch ( ParseException e )
e.printStackTrace();
System.out.println(n);
myRow.add(n);
//myRow.add(String.valueOf(cell.getNumericCellValue()).trim());
//System.out.println("numeric: " +cell.getNumericCellValue());
break;
case HSSFCell.CELL_TYPE_STRING:
myRow.add(cell.getStringCellValue().trim());
System.out.println("string: " + cell.getStringCellValue().trim());
break;
case HSSFCell.CELL_TYPE_BLANK:
myRow.add(" ");
System.out.println("add empty:");
break;
} // end switch
cellCount++;
} // end while
r++;
}// end while
} myRow is the arrayList i am adding the cells of the excel file to. I have checked for blank spaces in my coding so please help with how to check for the black spaces that has been added to my arraylist.
I have tried checking by looping through the ArrayList and then checking for null values like this
if(myRow.get(i)!=null)
// do something
// i have tried this also
if(myRow.get(i)!="")
//do something
}Edited by: nb123 on Feb 3, 2008 11:23 PMFrom your post I see you are using a 3rd party package to access the Excel SpreadSheets, you will have to look in your API for you 3rd party package and see if there is a method that will identify a blank row, if there is and it does not work, then you have to take that problem up with them. I know this is a pain, but it is the price we pay for 3rd party object use.
In the mean time, you can make a workaround by checking every column in your row and seeing if it is null, or perhaps even better: check and see if the trimmed value of each cell has a lenth of 0. -

Help: matrix report grid lines missing for null values only on server side
Hi,
I created a matrix report in pdf format. The output in great when run through report builder locally, it renders all necessary details. However, after the report being moved into AS server, the report does not show grid lines for null values.
It looks to me this has something to do with configurations and hope someone know what needs to be done.
Any suggestions are greatly appreciated.
JimmyThanks for replying.
DESFORMAT is PDF.
There should be a fix as I had same issue with same Oracle version at my previous company. DBA fixed the issue on AS server.
I found your post on 09/28/2010 with a link to patch set: Re: Null value fields disappear in pdf output format
We worked out with the work around without install the patch.

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? ThanksVikas - 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 to Check the total value of a field
Hi,
I want to check the total value of a field (this total is obtain by using property of that field thru personalization).
that means , in a table 3 columns are there (col 1, col2 & col3). I personalized the total property as true for col3.
now i'm getting the total for that field.
I want to check that total whether it crossed 100 or not.
How to do this?
Thanks in advance,
SANHi San,
You can achieve by using OATotalRowBean, search for OATotalRowBean in this forum you should be able to get some sample code.
public class OATotalRowBean
extends TotalRowBean
implements OAWebBean, OAWebBeanConstants
A special row rendered at the bottom of a table which lets users see totals for columns which are designated for summing.
Note The total is calculated and displayed only for visible rows.
When you indicate that you want to total one or more columns, the OA Framework creates an OATotalRowBean and designates it as the columnFooter named child of the OATableBean. If the OATableBean is also configured to insert rows (so it has an "Add Another Row" button), then the total bean becomes an indexed child of the add table row bean (see OAAddTableRowBean), which the OA Framework in turn designates as the table's columnFooter object.
If you need to access the table's column footer object for any reason, call the OATableBean's getColumnFooter() method. If row insertions are enabled, this method returns an OAAddTableRowBean; otherwise it returns an OATableRowBean.
For detailed information about creating and working with tables, see OA Framework Developer Guide: Tables.
With regards,
Kali.

What is the alternative for DisplayMemberPath="Value" for Windows Store applications?
I think there is a bug with Windows Store Applications when it comes to using DisplayMemberPath="Value".
Here is my code
<ComboBox Height="40" VerticalAlignment="Stretch" SelectedValuePath="Key" DisplayMemberPath="Value" x:Name="comboBox1" FontSize="25"/>
var source = new Dictionary<string, double>();
source.Add("Item1", 0.4);
source.Add("Item2", 0.3);
source.Add("Item3", 0.1);
source.Add("Item4", 0.1);
var formateDSource = new Dictionary<string, string>();
foreach (var item in source)
formateDSource.Add(string.Format("[{0}, {1}]", item.Key, item.Value), item.Key);
comboBox1.ItemsSource = source;
If you use this code in WPF in works perfectly. However if you use this code in a Windows Store Application then the Combo Box is empty and an error is thrown. So is there an alternative way to do this in Windows Store Applications and have I unearthed a
bug? Because I have researched the Web for days and found no solution to this.*please do not comment unless you have tried my code as a Windows Store App not a WPF in Visual Studios. Can Someone post an example based on my code that works in Windows Store
