Need To Check For Nulls And Force A Date

I'm trying to check to see if a field is blank (null or blank), if so, force a date into it. My formula is giving me zeros. What is wrong with the below formula ?
If {Sales_Primary.Type_Of_Sale} = 1 And
Isnull() Then 1999-01-01

My bad. I don't think Date Time fields have "empty strings" but rather 0's instead.
Try replacing the ="" with =0
If {Sales_Primary.Type_Of_Sale} = 1 And
(Isnull({TableName.Sales_Date}) OR {TableName.Sales_Date} = 0) Then #1/1/1999#
Or you could simply try it without the "OR {TableName.Sales_Date} = 0" and see what you get.
If {Sales_Primary.Type_Of_Sale} = 1 And
Isnull({TableName.Sales_Date}) Then #1/1/1999#

Check for null and empty - Arraylist

Hello all,
Can anyone tell me the best procedure to check for null and empty for an arraylist in a jsp using JSTL. I'm trying something like this;
<c:if test="${!empty sampleList}">
</c:if>
Help is greatly appreciated.
Thanks,
Greeshma...

A null check might not be you best option. If your requirement is you must have both the date and time component supplied in order to populate EventDate, then I would use a Script Functoid that takes data and time as parameters.
In the C# method, first check if either is an empty string, if so return an empty string.
If not, TryParse the data, if successful, return a valid data string for EventDate. If not, error or return empty string, whichever satsifies the requirement.

Checking for nulls

I have a string variable and I need to check for null.
What is the best way to do this?
Thanks.

You can also do it like this:
} catch (NullPointerException e) {or like this:
s==null ? <...> : <...>

Check for null or empty in the functoid

I want to check for null and empty values on input source node. If there exists a null or empty in the input source node, I should not pass that to output destination node. Does the
following attachment work? I want to check for null or empty in the date and time and then concatenate them to send to output. If any of them is null or empty, the other should not fail. In the Not Equal Functoid I am checking for blank, but how to check for
null?

I have installed itunes 10.7 several times. All goes well. After reboot, I go into itunes and check for updates and it says I need to download the update 10.7! (And so cant sync with my Iphone)

I have installed itunes 10.7 several times, all goes well. After reeboot, I go to check for updates and it still wants to update to version 10.7! I cant sync to my iphone4 because I get an error message saying I need version 10.6.3 or later. Help

Thank you for getting me started on the track by mentioning "Revo" Uninstaller. The results of "Revo" spoke volumns on why a successful install of ITunes is so difficult to achieve. It is the evil "BONJOUR".
I then tripped upon the following site by Apple and the detailed directions (I read, printed, re-read and followed the instructions. It was intense) brought a successful ITunes, Quick Time and the lovely Bonjour home. Thank you for the start JD42.

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.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..
Cheers,
Hari

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
Rajesh

Thanks 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
Rajesh

Page Validation - Function Returning Boolean - Check for NULL

I have 3 Page Validations which all fire on "When Button Pressed" = "Submit".
 
Number 1 is of type "Item specified is NOT NULL" for "P199_BUSINESS_UNIT1".
 
Number 2 is of type "Item specified is NOT NULL" for "P199_BUSINESS_UNIT2".
 
Number 3 is of type "Function Returning Boolean" and has the following code:
 
IF :P199_BUSINESS_UNIT1 IS NULL AND
 :P199_BUSINESS_UNIT2 IS NULL THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ; 
When P199_BUSINESS_UNIT1 is NULL and P199_BUSINESS_UNIT2 is NOT NULL, I get the Error from Validation 1. Perfect.
 
When P199_BUSINESS_UNIT1 is NOT NULL and P199_BUSINESS_UNIT2 is NULL, I get the Error from Validation 2. Perfect.
 
When P199_BUSINESS_UNIT1 is NOT NULL and P199_BUSINESS_UNIT2 is NOT NULL, I don't get an Error Message. Perfect.
 
When P199_BUSINESS_UNIT1 is NULL and P199_BUSINESS_UNIT2 is NULL, I get Error Message 1 & 2, but nothing from 3.
 
If I change the code to:
 
IF :P199_BUSINESS_UNIT1 = '01' AND
 :P199_BUSINESS_UNIT2 = '01' THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ; 
and change both values to '01', I get the appropriate Error Message.
 
What is going on? Is there some reason I can't check for NULL in a Function Returning Boolean?

Scott,
 
Instead of adding the Validations, I changed my code from:
 
IF :P199_BUSINESS_UNIT1 IS NULL AND
 :P199_BUSINESS_UNIT2 IS NULL THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ;
 to the following and got the desired results:
 
IF REPLACE(:P199_BUSINESS_UNIT1,'%null' || '%',NULL) IS NULL AND
 REPLACE(:P199_BUSINESS_UNIT2,'%null' || '%',NULL) IS NULL THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ; 
Note that I changed the word REPLACE to upper case and the second occurrence of the word NULL to upper case to accentuate the fact that the '%null' is case sensitive, using "%NULL' does not work, it has to be "%null' in lower case.
 
Thanks for your help.

How do I check for null date entires using custom JScript on a SharePoint NewForm.aspx?

Hi,
I have the below JScript:
/*Function to convert the US Date format to UK date format */
function parseDate(input) {
var parts = input.split('/');
// new Date(year, month [, date [, hours[, minutes[, seconds[, ms]]]]])
return new Date(parts[2], parts[1]-1, parts[0]); // months are 0-based
/*Function to check if end date is before the start date */
function checkDates(){
var sd = parseDate($("input[title='From']").val());
var ed = parseDate($("input[title='Until']").val());
if(sd > ed) {
alert("Please check From and Until Date");
$("input[value$='Save']").attr('disabled', true); //hide save button
else
$("input[value$='Save']").attr('disabled', false); //show save button
The above works fine for checking sd > ed but I can't seem to check for null's, I have attempted the below which doesn't work:
/*Function to convert the US Date format to UK date format */
function parseDate(input) {
var parts = input.split('/');
// new Date(year, month [, date [, hours[, minutes[, seconds[, ms]]]]])
return new Date(parts[2], parts[1]-1, parts[0]); // months are 0-based
/*Function to check if end date is before the start date */
function checkDates(){
var sd = parseDate($("input[title='From']").val());
var ed = parseDate($("input[title='Until']").val());
if( (sd > ed) || (sd == null) || (ed == Null) ) {
alert("Please check From and Until Date");
$("input[value$='Save']").attr('disabled', true); //hide save button
else
$("input[value$='Save']").attr('disabled', false); //show save button
Any help appreciated.

                         }// 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

From 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.

Can't check for nulls in a conditional?

Hey everyone. Trying my hand at a text based game but I'm encountering many problems:
I have this method in one class that (as you can see) has a conditional that checks to see if 'check' is null, this throws a null pointer exception whenever it is called.
private void placeChars()
 String check = currentItem.getItemString();
 if(check.equals(null) && currentRoom.getShortDescription().equals("in the cafeteria"))
 josh.getSentence(0);
 }Here is the method that it is calling from:
public String getItemString()
 String returnString = null;
 if(haveItems != 0 ){
 returnString = "Items:";
 Set<String> keys = items.keySet();
 for(String item : keys) {
 returnString += " " + item;
 return returnString;
 }I'm not sure what I am doing wrong here :/ and yes I know the code is extremely ugly :)

if check is null, you can't invoke any methods on it, including equals.
To check for null:
if (check == null)

Check for null in IF statement

Hi,
I have a variable of type char(8).
I want to check if this field is empty. This is the logic I use right now:
condense lv_date no-gaps.
if lv_date eq ''.
*then some default value
endif.
Is this the correct approach or there is a way to directly check for null values in a variable.
Thanks,
CD

Hello,
You have to check IS INITIAL.
condense lv_date no-gaps.
if lv_date IS INITIAL.
*then some default value
endif.

Suhas
