Varchar Column Returning Null Value

Hi
I have a report with a subquery which contains a dynamic from clause which is set by the main query, the report returns date and number values from the view in the subquery but does not return varchar2 values, if I select the varchar2 values from the view in sqlplus then the value is returned.
Any help would be much appreciated thanks,
Dereck

Please check the elasticity of the field in the Report Layout where you are returning the varchar2 value.

How to take the Average of a DATEDIFF column with NULL values?

I am building an SSRS report that can display the average of a calculated datediff column in dd/hh/mm format with the following formula:
=Avg(IIF(Fields!LastCorrectedDate.Value is nothing,0, DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) \(60*24) & ":" & DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) mod (60*24)\60 & ":" & DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) mod (60*24) - (((DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) mod (60*24))\60)*60) ))
SSRS does not raise any errors with the formula and I have used the same formula for other columns without issue. I have noticed that this column includes null values which I think may be the problem. When the reports runs, it returns #ERROR on the column
but does not give a reason why. I am using SSRS report builder with visual basic logic as opposed to embedding SQL. Any help or feedback would be greatly appreciated.

Hi No Ragrets,
According to your description, you want to calculate the average for the date time difference. Right?
In Reporting Services, Avg() function is only available for numeric values. In this scenario, the DateDiff() function to calculate the minutes difference will return a number. So we can do average calculation based on the return values first. Then we format
it as a time. We have tested this case in our local environment. Please try the following expression:
=floor(avg(DateDiff("n",Fields!StartDate.Value,Fields!EndDate.Value))) \(24*60) &":"&
floor(avg(DateDiff("n",Fields!StartDate.Value,Fields!EndDate.Value))/60 mod 24 )&":"&
floor(avg(DateDiff("n",Fields!StartDate.Value,Fields!EndDate.Value))) mod 60
The result looks like below:
If you have any question, please feel free to ask.

Reading User Profile Properties pragmatically in SharePoint 2010 Returns Null Values Although it has values returned from AD
I configured the user profile service application and run Sync and user profiles and its properties returned from Active directory but when I want to read it pragmatically it returns null values.
this is my code...
void runQueryButton_Click(object sender, EventArgs e)
// Get the My Sites site collection, ensuring proper disposal
using (SPSite mySitesCollection = new SPSite("http://sp/my"))
//Get the user profile manager
SPServiceContext context = SPServiceContext.GetContext(mySitesCollection);

Hi,
Please try with the following code

Sql query slowness due to rank and columns with null values:


Sql query slowness due to rank and columns with null values:
I have the following table in database with around 10 millions records:
Declaration:
create table PropertyOwners (
[Key] int not null primary key,
PropertyKey int not null,
BoughtDate DateTime,
OwnerKey int null,
GroupKey int null
go
[Key] is primary key and combination of PropertyKey, BoughtDate, OwnerKey and GroupKey is unique.
With the following index:
CREATE NONCLUSTERED INDEX [IX_PropertyOwners] ON [dbo].[PropertyOwners]
[PropertyKey] ASC,
[BoughtDate] DESC,
[OwnerKey] DESC,
[GroupKey] DESC
go
Description of the case:
For single BoughtDate one property can belong to multiple owners or single group, for single record there can either be OwnerKey or GroupKey but not both so one of them will be null for each record. I am trying to retrieve the data from the table using
following query for the OwnerKey. If there are same property rows for owners and group at the same time than the rows having OwnerKey with be preferred, that is why I am using "OwnerKey desc" in Rank function.
declare @ownerKey int = 40000
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from (
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
) as result
where result.[Rank]=1 and result.[OwnerKey]=@ownerKey
It is taking 2-3 seconds to get the records which is too slow, similar time it is taking as I try to get the records using the GroupKey. But when I tried to get the records for the PropertyKey with the same query, it is executing in 10 milliseconds.
May be the slowness is due to as OwnerKey/GroupKey in the table can be null and sql server in unable to index it. I have also tried to use the Indexed view to pre ranked them but I can't use it in my query as Rank function is not supported in indexed
view.
Please note this table is updated once a day and using Sql Server 2008 R2. Any help will be greatly appreciated.

create table #result (PropertyKey int not null, BoughtDate datetime, OwnerKey int null, GroupKey int null, [Rank] int not null)Create index idx ON #result(OwnerKey ,rnk)
insert into #result(PropertyKey, BoughtDate, OwnerKey, GroupKey, [Rank])
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
go
declare @ownerKey int = 1
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from #result as result
where result.[Rank]=1
and result.[OwnerKey]=@ownerKey
go

How to check the sql:query is return null value

I have use :
<sql:query var="sql1" dataSource="${db}">
select col_name from table_name
where a=<c:out value="${row.test1}"/>
and b='<c:out value="${row.test2}"/>'
</sql:query>
So, how can I check this statement return null value which is no record within this table?

The Result should never be null but can be empty. You can check if the Result is empty using an if tag and checking the rowCount property:
    <sql:query var="books"
      sql="select * from PUBLIC.books where id = ?" >
      <sql:param value="${bookId}" />
    </sql:query>
     <c:if test="${books.rowCount > 0}">
     </c:if>http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSTL7.html#wp84217

ORA-01405 in Pro*C Although no Column has NULL Value

I have a Pro*C program that fetch a cursor from Oracle 8.1.5 into host variables without indicators. I have tried the SQL statement and the SQL will never return any NULL value in any column, however I still got the ORA-01405 error. Any one has any clue?

Binding for "File Content Repository Path" is returning null value

I have created a data control for file based content repository based on an existing file system path. *But when this data contol is invoked the command "#{bindings['getURI_returnURI'].inputValue}" is returning null.*+
Please advice what are possible scenarios. I have performed the following
#1. Create a file system folder in windows XP named "C:\CPContentRepository" and add some html pages into this folder.
#2. Create a "content" project in the application.
#3. Create a "Content Repository Data Control" named "CPFileContentRepository". Repository Type : "File System", Base Path : "C:\CPContentRepository". Test & Registration is successful.
#4. Add a "panel horizontal" into jsf jsp "ContentTest" page & drap-dop data control "CPFileContentRepository--> getURI(String)--> Return--> URI". select return type as "ADF Output Text".
#5. Edit Authorization of the "ContentTest" page definition for "View --> anyone".
#6. Edit Authorization of the "ContentTest" page definition bindings "getURI" for "Invoke --> anyone".
#7. Run the "ContentTest" page. The output for the page is empty.

There're two major problems in your code. One you have used different names to get your parameters like in your first jsp they're like
<input type="text" name="did" size="20" </p>
<p align="center"> </p>
<p align="center"><b>Name        </b>
<input type="text" name="name" size="20"></p>
<p align="center"> </p>
<p align="center"><b>Specialist In
<input type="text" name="specialist" size="20"></b></p>
<p align="center"> </p>
<p align="center"><b>Address
<input type="text" name="address" size="20"></b></p>
<p align="center"> </p>
<p align="center"><b>Phone no.
<input type="text" name="phno" size="20"></b></p>
<p align="center"> </p>but when you're getting you're doing it like this
String name = request.getParameter("name");
     String did = request.getString("did");
     String add = request.getParameter("add");
     String specilist = request.getParameter("specilist");
     String phno = request.getParameter("phno");First get them with same name as you have them in your first jsp. another thing in that you're not used form tag in write way... You have created submit button in some other form
and when you're pressing submit button actully you're submitting only that form value and your form1 is not submitted that's why you're getting null values for
those parameters you're getting with right name

Webservice returns null values (Flex)

Hi all,
I created a webservice in abap,
(a RFC and a Function Web Service).
It exports a table type and contains data from a Ztable.
When i request it from Flex, it returns rows, but they contain NULL values, why ?
I can request and display bapi webservices that comes with in SapNetweaver trial 7.1 but i cant display my own webservice.
Result like this;
result     generated.webservices.ZCUSTOMERS_TT (@2205981)

it is true that there are 4 rows in table, but all client, id and name is null
why ?

thanks for answer but my problem didint solved.
My webservice can return normal values like integer or decimal and i can read it from flex.
but when i try to view tables, i always get null values BUT item count is true :=) i have 4 item in z table and 4 rows returns in array from webservice but NULL values :=).
I can't return structure as well.

Component binding return null value

I'm migrating a JSF 1.2 application to JSF 2.1, specificly I'm currently using mojorra 2.1.24.
The application consists of request scoped beans, and in order to pass data between requests, it embeds the data inside UI components.
The following behaviour works well with JSF 1.2, but not with JSF 2.1.
The application has the following configuration:
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
The page contains the following snippet:
<h:form prependId="false">
     <h:inputHidden binding="#{bean.inputHidden}" />
     <h:panelGroup rendered="#{bean.rendered}">
      <h:commandLink value="onAction" action="#{bean.onAction}" />
     </h:panelGroup>
</h:form>
The bean is the following:
@ManagedBean
@RequestScoped
public class Bean {
private UIInput inputHidden;
private AItem item;
public setInputHidden(UIInput inputHidden){
    this.inputHidden = inputHidden;
    if(item != null){ this.inputHidden.setValue(item); }
public AItem getItem(){
    return (AItem) getInputHidden().getValue();
// other getter/setter
public String onNavToPage(AItem item){ this.item = item; return "page"; }
public String onAction(){ //... do something return ""; }
public boolean isRendered(){ return getProcessItem() != null; }
The steps are the following:
to navigate to page page the method bean.onNavToPage is invoked from within another page;
upon page rendering the bean.item is set as bean.inputHidden value;
after the page is diplayed, the command link is pressed.
At this point no command link is invoked, because the bean.inputHidden.getValue() returns null, and the command link is not processed.
I noticed that the inputHidden parameter passed to the setInputHidden method during restore view phase has, inputHidden.getValue() == null, no value has been saved previously in the view.
I would guess that something has changed in the component state management, but debugging the JSF code I didn't find what.
Debugging JSF code I found that the component state has been masked before the state has been saved in the view, so the ComponentStateHelper.saveState saves the deltaMap and not the defaultMap, where all the state has been put.
public Object saveState(FacesContext context) {
        if (context == null) {
            throw new NullPointerException();
        if(component.initialStateMarked()) {
            return saveMap(context, deltaMap);
        else {
            return saveMap(context, defaultMap);
is this a bug?
If not, how can I restore JSF 1.2 behaviuor and save the defaultMap?
Thanks in advance for the help.

Web Service Operation returns null values

I got a Flash program that uses a Web Service. I linked the actionscript to the Flex Files to get my connection to work. I got it to work fine, but the problem is with sending it parameters. This only works on functions without parameters. But when I try to pass parameters, it returns null. I also tried using the argruments function, but that caused it to return error. What do I do to make it work? Here is my code below:

function BuildServiceRequest(evt:LoadEvent){
          /*loginOperation = webService.getOperation("GuestLogin");
          loginOperation.send(nickname, token, gameName);
          //nickname = name_input.text;
          loginOperation.addEventListener(FaultEvent.FAULT, DisplayError);
          loginOperation.addEventListener(ResultEvent.RESULT, DisplayResult);*/
          trace("connected");
function login(event: MouseEvent): void{
          loginOperation = webService.getOperation("GuestLogin");
          //nickname = name_input.text;
          loginOperation.addEventListener(FaultEvent.FAULT, DisplayError);
          loginOperation.addEventListener(ResultEvent.RESULT, DisplayResult);
          //loginOperation({Nickname: nickname, Token: token, GameName: gameName});
          //loginOperation.arguments = {nickname: "GGG", Token: "token", GameName: "gameName"};
          loginOperation.send([nickname, token, gameName]);
function DisplayError(evt:FaultEvent){
                              trace("error");
function DisplayResult(evt:ResultEvent)
          var wsdlResponse:String = evt.result as String;
          trace(wsdlResponse);
function sendLogin(nickname: String, token: String, gameName: String): String{
          return nickname + token + gameName;

Shay,
The link worked. I generated Java Web Service from my WSDL, and tested using the HTTP analyzer
But for get Operation method on the WSDL, I could not see anything in the response object, but the same operation i could see the output in soapUIPro.
Can you give me some more guildelines to debug...
Thanks,
Sri

This query returns values for SC/ST and General as there is no matching data for the PWD. But I want to display PWD with value 0 in the report. How to do this? Can anyone help me in this matter at the earliest?
Regards

hello,
u r calculating the cast in ur detail table applicationformatdtl.
and also u have the table of caste in which caste description is given
so ur query like this
select nvl(decode(a.caste,1,'sc/st',2,'general'),'pwd')cast,
nvl(a.caste,40),decode(count(*),1,0,count(*),count(*)) total
from applicationformdtl a,caste c where c.caste = a.caste(+) group by a.caste
which gives the output
caste total
sc/st 3
general 5
pwd 0

Hidden field in form returns null value

Hi all - I searched for this but found nothing that fit my problem although various other problems came up.
I have a Login jsp, with a simple form for username and password:
<form name="login" method="post" action="servlet/ControlServlet"
onSubmit="return validateForm()"><table width="180" border="0"
cellspacing="0" cellpadding="0">
            <tr>
              <td width="96" class="logintext">Username</td>
              <td width="84"> </td>
            </tr>
            <tr>
              <td><input name="username" type="text" size="15"
maxlength="15"></td>
              <td><input type="submit" name="Submit" value="Login"></td>
            </tr>
            <tr>
              <td class="logintext">Password</td>
              <td> </td>
            </tr>
            <tr>
              <td class="logintext"><input name="password" type="password"
size="15" maxlength="15"></td>
              <td><input name="actionCode" type="hidden" value="0"></td>
            </tr>
            <tr>
              <td> </td>
              <td><div align="center"><a href
="Register.jsp"><i>Register</i></a></div></td>
            </tr>
          </table>
          </form>Nothing complex in that form. my hidden field is actionCode and it should pass a 0 to my ControlServlet servlet.
Here is a snippet from my servlet:
import java.io.* ;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ControlServlet extends HttpServlet {
public void doPost(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    response.setContentType("text/html");
            //get the printwriter to output for debugging
            PrintWriter out = response.getWriter();
            //read in form variables
        //String formUsername = request.getParameter("username");
        //String formPassword = request.getParameter("password");
        String action = request.getParameter("actionCode");
        //convert String to int for action
        //int actionInt = Integer.parseInt(action);
        //add action variable to request
        request.setAttribute("aktion", action);
            //debug point 1
            //use requestDispatcher to forward session info to JSP
           RequestDispatcher dispatcher =
           request.getRequestDispatcher("/mvcoutput.jsp");
           dispatcher.forward(request, response);I have commented out a bit for debugging purposes, but basically, the form variables are read in, the username and password don't give me any problems, but the actionCode does. Upon forwarding to a basic jsp for testing my output displays value "null" when using the command:
request.getAttribute("aktion")Any reason why the hidden field is playing silly buggers ??
cheers

Anyone ???
If I have a field in an html form which is hidden, do I retrieve it in the SAME WAY that I retrieve the non hidden form fields i.e. using the request.getParameter() method ??
Cheers.

Fact column shows null values in report

Hi Experts,
I have a requirement where i need to create report from a Dimension Dim1 and 2 Fact Tables Fact1, Fact2 with the columns as Dim1.State, Fact1.Price, Fact1.Source,Fact2.Market Value. The two fact tables are at different granularity, when i run the report it is issuing the query only from Fact 1 and putting NULL for the column from Fact 2. Can someone guide me on how to approach.
Thanks,
Chandrasekhar

Welcome to the magic world of content level.
You give yourself the answer to your issue: "the two fact tables are at different granularity" (95% of chances you are just on that case for your issue).
