If(isset || empty)!

Hello,
I was hoping someone could give me the equivalent to PHPs
if(isset) and if(empty) operators. I checked Adobe's ActionScript
Dictionary and came up with nothing. Please help! I need an element
that can check to see if a field (text, date, etc...) is empty or
not.
Would greatly appreciate any input, this project is for work.
Thanks in advance,
Michael Loring

In ActionScript 3, you can test for null when it comes to any
object class. For Number, you can can use isNaN (is not-a-number);
Booleans can either be true or false. If you can have 'unset'
Boolean, it is false by default.
var amount:Number; // use isNaN(amount)
var name:String; // use name == null
var person:Person; // use person == null

PHP+MySQL query with empty value

Hi!
Software is DW8 with Apache 2.0.48, MySQL ver. 4.0.15a, PHP
4.2.3.
We had problem when a submitted value for 'regionID' in the
submit page
was left blank and the following error message appears in the
result page:
"You have an error in your SQL syntax. Check the manual that
corresponds
to your MySQL server version for the right syntax to use near
'LIMIT 0,
3' at line 1"
The problem was solved by adding at the top of the page:
<?php
if (isset($_POST['regionID']) &&
empty($_POST['regionID'])) {
$_POST['regionID'] = '0';
?>
How to change the above code to retrieve ALL records when an
empty \
blank value is submitted for 'regionID'?
TIA

I'm afraid you've picked up rather poor information.
$_REQUEST relies on
register_globals being turned on. Since register_globals is
considered a
major security risk, the default setting has been off since
April 2002.
Many hosting companies have turned register_globals on, in
spite of the
security problems, because so many poorly written scripts
rely on it.
The PHP development team has decided to resolve this security
issue once
and for all by removing register_globals from PHP 6.
Forget $_REQUEST. Use $_POST and $_GET always. It's safer,
and it's
futureproof.

Php emptying $_post

hello
i am having a play trying to create a simple shopping checkout, using code, no specialist software.
everything is working fine, except when i add or delete an item, and refresh the page, the add/delete is being repeated. which is obviousley bad.
i've tried unsetting the $_posts and emptying any variable being used, but this isn't doing the trick. any ideas....p.s, i'm trying to get the delete item code to work first, so have not altered my add item code.
to test the page, go to http://www.malcmabe.co.uk/custdetails.php
create a username and password using the top columns.click on search for items, and type 'nike' into the search box. click on one of the products and then add x amount to the basket.
if you then f5 refresh, the process is repeated.
in the item code column, type in the item code of the product you have chosen, and choose a quantity to delete. this will delete fine, but if you f5 refresh, another deletion takes place.
here is the code for deletion process:
if(isset($_POST['delitem']))
$code = $_POST['itemcode'];
$quant = $_POST['delquant'];
print("<br/> ".$code." ".$quant);
mysql_query("delete from checkout where itemid = '$code' and username = '$username' LIMIT $quant ");
unset($_POST['delitem']);
unset($_POST['itemcode']);
unset($_POST['delquant']);
$code = null;
$quant = null;
i would appreciate any help. thanks

thanks david
but what i'm getting at, is that if the user adds or deletes an item, and then refreshes for whatever reason, than another item will be added or deleted.
basically, i want no post items to be sent when they refresh the page.
the only time i want data to be sent is when they press a button.

Empty field

I have a username field, and if the user changed their username already, change_uname will = 1. then, the text field for username will be disabled. here is my code:
<input type="text" name="uname" <?php if($change_uname == 1) { echo "disabled='disabled'"; } ?> value="<?php echo $uname; ?>">
and the php code:
if(isset($_POST['modify'])) {
$uname = $_POST['uname'];
echo "username: " . $_POST['uname'];
the only problem is, when change_uname = 1, it's not able to retreive the username...

Hi,
The Empty Fields is used when a field is missing from the Source and all the values in the Source are Null.
When this field is required, then we do not need to add this field in the Source. Infact, we can do this in Import Manager also. Provided the only Value in this source field is NULL
1. Then You use this option of Empty Fields by Adding a Field in the Source hierarchy.
2. Map the Added field to the Destination
3. Map the Null Value to the Destination value.
For further understanding , Please refer page No- 90 & 228.
Hope it helps.
Thanks and Regards

I would be greatfull for any help

I have managed to solve the problem.
In the end I didn't check if the values were empty, as it worked fine without. However the switch of the price didn't work in combination with the rest of the query.
I've solved the problem as follows:
$varCategory_rsgetsearch2 = "%";
if (isset($_GET['Category'])) {
$varCategory_rsgetsearch2 = $_GET['Category'];
$varMake_rsgetsearch2 = "%";
if (isset($_GET['Manufacturer'])) {
$varMake_rsgetsearch2 = $_GET['Manufacturer'];
$varColor_rsgetsearch2 = "%";
if (isset($_GET['Color'])) {
$varColor_rsgetsearch2 = $_GET['Color'];
$varPrice_rsgetsearch2 = "%";
if (isset($_GET['Keysound_price'])) {
$varPrice_rsgetsearch2 = $_GET['price'];
mysql_select_db($database_dBconn, $dBconn);
$query_rsgetsearch2 = sprintf("SELECT * FROM products WHERE Category LIKE %s AND products.Manufacturer LIKE %s AND products.Color LIKE %s", GetSQLValueString("%" . $varCategory_rsgetsearch2 . "%", "text"),GetSQLValueString("%" . $varMake_rsgetsearch2 . "%", "text"),GetSQLValueString("%" . $varColor_rsgetsearch2 . "%", "text") );
switch( $_GET['price'] ){
        case '0-500':
        $query_rsgetsearch2 .= ' AND price BETWEEN 0 AND 500 ORDER BY price ASC';
        break;
          case '500-1000':
        $query_rsgetsearch2 .= ' AND price BETWEEN 500 AND 1000 ORDER BYprice ASC';
        break;
                    case '1000-2000':
        $query_rsgetsearch2 .= ' AND price BETWEEN 1000 AND 2000 ORDER BY price ASC';
        break;
          case '2000':
        $query_rsgetsearch2 .= ' AND price BETWEEN 2000 AND 10000 ORDER BY price ASC';
        break;
$query_limit_rsgetsearch2 = sprintf("%s LIMIT %d, %d", $query_rsgetsearch2, $startRow_rsgetsearch2, $maxRows_rsgetsearch2);
$rsgetsearch2 = mysql_query($query_limit_rsgetsearch2, $dBconn) or die(mysql_error());
$row_rsgetsearch2 = mysql_fetch_assoc($rsgetsearch2);
I'm sure that you can keep the checking for values in, however for me the was no need for it anymore.
Thanks for all your help

Ignore Empty Parameter

I am trying to create a form that searches through a recordset. I am wondering, if several of the fields within the search form are left blank when submitted by the "GET" method, how I can have the query string ignore those empty parameters in the URL. I posted a similar question a little earlier and got no responses. I'm a newbie so let me now if I'm not phrasing my question correctly or something.

I've attempted to use the longer version of the code to make my select statement work. This is the code that I've got now:
$query_rs_results = "SELECT dogid, b_email, b_fname, b_lname, b_phone, b_url, dob, dod, reg_name, reg_no, o_email, o_fname, o_lname, o_phone, o_url, registry, semen_l, semen_f, semen_fc, semen_fr, photo FROM dog_main";

The results page is displaying every dog in the database.
What am I missing here?

Cannot assign an empty string to a parameter with JDBC type VARCHAR

Hi,
I am seeing the aforementioned error in the logs. I am guessing its happening whenever I am starting an agent instance in PCo. Can somebody explain whats going on?
Regards,
Chanti.
Heres the complete detail from logs -

Sounds like a UI browsing bug (when no path is selected from a catalog tree folder browser) - I would suggest logging a support ticket so that it can be addressed.

Oracle, Null and empty Strings

Currently I'm facing problems with a class, which contains a String, which
is set to "" (empty String).
When the class is persistent, oracle writes null to the table column
(which seems to be common oracle behaviour) and when retrieving the class,
the field is set to null as well, giving me a lot of null-pointer
exceptions.
Anyway ... I can cope with that (just a lot of extra work)
far worse is the problem, wenn searching objects, that have this field set
to "" oder null.
Oracle can't find the records because JDO creates Querys "where
string=null" or "where string=''" , where oracle expects "where string is
null" to find the records.
Is there a workaround or solution ?

Yeah, that would work as well, thx, but since I have to cope with
null-Strings now everywhere in my program, it doesn't hurt just to forbid
empty strings on the program side.
In future times I'll test on Oracle first, then porting to DB/2 - this way
I suppose work is far less to garant compability.
Nevertheless ... having to set the bankcode into quotes is a kodo bug in
my opinion.
Kodo knows the type of classfields (in this case string) and shouldn't
send the parameter as a BigDecimal to the database.
Given that, and having only bankcodes of null (only neccesary when using
Oracle), the method would look like:
public Collection getAccounts (String bankCode)
throws Exception
return getAccounts (Account.class, "bankcode=="+bankcode);
which is how a transparent persistent layer, um, should be , um , I mean
... just transparent ;-D

Couldn't you just do something like:
public Collection getAccounts (String bankCode)
throws Exception
String filter;
if (bankCode == null || bankCode.length () == 0)
filter = "(bankCode == null || bankCode == "")";
else
filter = "bankCode == "" + bankCode + """;
return getAccounts (Account.class, filter);
If I understand the problem correctly, this should work for all the
databases.

What operations are you performing to cause this SQL to be issued? You

DELETE statement. Is this the SQL that is issued when looking up
objects by identity?I'm not removing objects, I was removing just quotes from parameters ;-)
A string column... is it also represented as a string field in your class?Yeah ... just to give you an impression of the code:
First we have a class, representing a bank account:
public class Account {
private AccountMgr myAccountMgr;
private String bankCode;
private String id;
Note, that in nearly all cases bankCode will be a number or null.
I have a second class "AccountMgr", which does all of the persistant stuff
(seaching, making persistent etc.)
This class has two methods, one versatile (protected) to retrieve accounts
by a given filterString and one who just returns accounts by bankCode,
building the expected filterstring. Here is my current working version:
public class AccountMgr {
public Collection getAccounts(String bankCode) throws Exception {
if (bankCode!=null) {
if (bankCode.equals("")) {
throw new Exception("check code, bankCode='' not allowed to get
same behavior from DB2 and Oracle");
// if set, quote the bankCode
bankCode="""+bankCode+""";
return getAccounts(Account.class,"bankCode=="+bankCode);
protected Collection getAccounts(Class accountClass, String filterAdd)
throws Exception {
PersistenceManager pm = MyHelper.getPersistenceManager();
String filter="";
if (filterAdd!=null && !filterAdd.trim().equals("")) {
filter+=filterAdd + " && ";
filter += "myAccountMgr==_accMgr";
Query query = pm.newQuery(accountClass, filter);
query.declareParameters("AccountMgr _accMgr");
return (Collection) query.execute(this);
As you can see, in the first method I have to set the bankCode into
quotes, when it's not null.
This is because otherwise a filter like "bankCode=1234" will be translated
in a way, where 1234 is send as a BigDecimal to the database:
[...] executing statement <4239745>: (SELECT [...] FROM JDO_ACCOUNT t0
WHERE t0.BANKCODE = ? : [reused=1;params={(BigDecimal) 1234}]

NULL and Empty String

Hi There,
As far as I know, Null is not the same as an empty string; however, when I try this out, I get some unexpected results (well, at least unexpected for my liking):
SQL> CREATE TABLE TS (MID NUMBER,
2 MDESC VARCHAR2(20) DEFAULT '' NOT NULL);
Table created.
SQL> INSERT INTO TS VALUES(1,'');
INSERT INTO TS VALUES(1,'')
ERROR at line 1:
ORA-01400: cannot insert NULL into ("TT"."TS"."MDESC")So, according to the above scenario, I can't insert an empty string!! However, an empty string is a valid string that doesn't have tuples/data!!
How come Oracle translates the null string '' as NULL?
Thanks

Null and empty string not being the same in object?

Hello,
I know that null and empty string are interpreted the same in oracle.
However I discovered the strange behaviour concerning user defined objects:
create or replace
TYPE object AS OBJECT (
value VARCHAR2(2000)
declare
xml xmltype;
obj object;
begin
obj := object('abcd');
xml := xmltype(obj);
dbms_output.put_line(xml.getStringVal());
obj.value := '';
xml := xmltype(obj);
dbms_output.put_line(xml.getStringVal());
obj.value := null;
xml := xmltype(obj);
dbms_output.put_line(xml.getStringVal());
end;
When creating xml from object, all not-null fields are transformed into xml tag.
I supposed that obj.value being either '' or null will lead to the same result.
However this is output from Oracle 9i:
<OBJECT_ID><VALUE>abcd</VALUE></OBJECT_ID>
<OBJECT_ID><VALUE></VALUE></OBJECT_ID>
<OBJECT_ID/>
Oracle 10g behaves as expected:
<OBJECT><VALUE>abcd</VALUE></OBJECT>
<OBJECT/>
<OBJECT/>
However Oracle 9i behaviour leads me to the conclusion that oracle
must somehow distinguish between empty string and null in user defined objects...
Can someone clarify this behaviour?
Thus is it possible to test if object's field is empty or null?

I think you can safely assume that null and empty strings are treated the same by Oracle regardless. If you're using anything less than 10g, it's not supported any more anyway, so upgrade. Don't rely on any assumptions that may appear due to bugs.

Difference in Null and Empty String

Hi,
I have been wondering about the difference between Null and Empty String in Java. So I wrote a small program like this:
public class CompareEmptyAndNullString {
     public static void main(String args[]) {
          String sNull = null;
          String sEmpty = "";
          try {
               if (sNull.equalsIgnoreCase(sEmpty)) {
                    System.out.println("Null and Empty Strings are Equal");
               } else {
                    System.out.println("Null and Empty Strings are Equal");
          } catch (Exception e) {
               e.printStackTrace();
This program throws Exception: java.lang.NullPointerException
     at practice.programs.CompareEmptyAndNullString.main(CompareEmptyAndNullString.java:10)
Now if I change the IF Clause to if (sEmpty.equalsIgnoreCase(sNull)) then the Program outputs this: Null and Empty Strings are Equal
Can anyone explain why this would happen ?
Thanks in Advance !!

Saish,
Whether you do any of the following code, the JUnit Test always passes: I mean he NOT Sign doesnt make a difference ...
assert (! "".equals(null));
assert ("".equals(null));
You probably have assertions turned off. Note the the assert keyword has nothing to do with JUnit tests.
I think that older versions of JUnit, before assert was a language keyword (which started in 1.4 or 1.5), had a method called assert. Thus, if you have old-style JUnit tests, they might still compile, but the behavior is completely different from what it was in JUnit, and has nothing to do with JUnit at all.
If you turn assertions on (-ea flag in the JVM command line, I think), the second one will throw AssertionError.

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.

Interactive Report view is empty

Hi,
I'm on CRM 7.0 EHP3. I'm encountering empty report criteria and display when open the Campaign effectiveness and all other interactive report page. Please see the screen shot below. There is no error message on the screen, as well as ST22.
I've configured the interactive report and ran the configuration wizard /CRMBW/CONFIG_WIZARD successfully and no error found.
Also the roles SAP_CRM_OR_ADMIN, SAP_CRM_OR_CONFIG and SAP_CRM_OR_USER and SAP_ALL are given to the user in both clients.
Please let me know what could be the causes.
Thanks in advance.
cheers,
julius

Okay, problem seems solved. I don't know if it is a bug or a feature... (: Anyway, this view selects data from threads that had been created from a portal application. And if you create threads from WC_Collaboration server admin console, there's no data will be selected with FORUMCRAWLER_VW view. Sorry, have no time to check SQL query for those DB view, may be this behaviour is reasonable.

Print empty report

Can I somehow print an empty report, and specify with a parameter how many times it should be repeated?
The report is a form with checkboxes, and sometimes we want the empty one for someone to fill in when out on the field. And since this form is a subreport, we cant print the entire report over again, but need the subreport to be repeated, let's say five times.
/Thank you!

Please re-post if this is still an issue or purchase a case and have a dedicated support engineer work with you directly

If(isset || empty)!
