Display columns for Null Values in Crosstab

Hi All,
I have developed a crosstab in CR based on SAP BW Query. Report requirement demands to display all columns even though data is not present for those columns. However this report doesn't show the columns when there is no data. Can you please help to resolve this issue !!!
Regards,
Samir

Samir,
As Abhilash stated, the crosstab rows/columns are like groups.
If you do not have a value to create a column, it will not show in the crosstab. Do you have a table that lists all the values you wish to show in the columns? Is it used in the report? Perhaps you can use it to create the columns by using a left outer link from the table with all the values to data table you are reporting on, and use it for your columns
If the columns are dates, and you do not have data for a particular date, that can be done.
[This post has a solution for a SQL server|How to dynamically create a table to join with;.
[Here is another solution|Generating Calendar Months for the year;.
There are other posts regarding this issue. I can not think of one at the moment for building a table for values other than a date but I am pretty sure I have seen one.

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.

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));

               } 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.

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 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..

How to check for null values in pl sql?

Hello,
I have an sql statement where I read the db column into a number of variables, some of the columns contain NULL values or empty varchars. How can I check if my variable contains any data?
Thanks,
J

to check if your variable contain null or not use like this
if v_variable is null if you use
if v_variable=NULL this is right according to syntax but it will not give you desired result
SQL> declare
2 v_empname varchar2(20);
3 v_comm number;
4 begin
5 select ename,comm into v_empname,v_comm from emp
6 where empno=7839 and comm is NULL;
7 dbms_output.put_line(v_empname);
8 if v_comm is NULL then
9 dbms_output.put_line(v_empname);
10 end if;
11 end;

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

Report is showing "null" string for null values.

Can you please help me to find solution for this ?.
Thank you very much in advance.

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.
Jimmy

Thanks 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.

Display comma for numeric values

Hi,
I want to display comma for numeric values.I know we can use strlen and concatenate, but any one can give me an example.
Ex: 1,234 and 12,234 , 1,22,500 ( iam expecting)
Thanks,
Veeru

it depends on ur data...
if it is currency then u can use
WRITE.... CURRENCY...
if it is qty then u can use
WRITE....UNIT....
or u simply pass it to a packed field and it will take the default decimal settings of the user profile...

Column values shift towards left for null values when export to excel

Post Author: pssuresh
CA Forum: Exporting
All,
I have a strange problem when using crystal report 10 export through C# Code. Consider in a row there are 3 columns and i am exporting to excel. ex.Student_id,Student_name,Student_Section. If Student_name values are null, then student_section values get displayed under student_name. There is a column shift towards left when there are null values. If anybody has already faced this problem, please post ur answer.
Note: When i just export to excel directly from crystal report, it works fine. i face problem only when i export through .Net code. I guess it is the problem with some formatting through code. if any body has fix, let me know.
Thanks,

In ColumnChart, how to stop displaying small column for zero value?

I'm trying to create a ColumnChart that does not display a column when the value is zero. The chart currently looks like this:
This is a stacked column chart with red values representing Faults and green values representing Throughput. Each hour has an explicit value of zero for Faults. I don't want to see any red lines when the value is zero. Is there any way to accomplish this?
My code looks like this:
<mx:Script><![CDATA[
     import mx.collections.ArrayCollection;
     [Bindable]
     public var simpleStats:ArrayCollection = new ArrayCollection([
        {Hour:"0:00", Throughput:0, ThroughputThreshold:2000, Faults:0, MaxResponseTime:450, AvgResponseTime:200, MinResponseTime:180,
             AuthenticationAcceptance:50, AuthenticationRejection:0, AuthorizationAcceptance:50, AuthorizationRejection:0},
        {Hour:"1:00", Throughput:0, ThroughputThreshold:2000, Faults:0, MaxResponseTime:450, AvgResponseTime:200, MinResponseTime:180,
             AuthenticationAcceptance:50, AuthenticationRejection:0, AuthorizationAcceptance:50, AuthorizationRejection:0},
        {Hour:"2:00", Throughput:0, ThroughputThreshold:2000, Faults:0, MaxResponseTime:450, AvgResponseTime:200, MinResponseTime:180,
             AuthenticationAcceptance:50, AuthenticationRejection:0, AuthorizationAcceptance:50, AuthorizationRejection:0},
        {Hour:"3:00", Throughput:5, ThroughputThreshold:2000, Faults:0, MaxResponseTime:450, AvgResponseTime:200, MinResponseTime:180,
             AuthenticationAcceptance:50, AuthenticationRejection:0, AuthorizationAcceptance:50, AuthorizationRejection:0},
        {Hour:"4:00", Throughput:0, ThroughputThreshold:2000, Faults:0, MaxResponseTime:450, AvgResponseTime:200, MinResponseTime:180,
             AuthenticationAcceptance:50, AuthenticationRejection:0, AuthorizationAcceptance:50, AuthorizationRejection:0}

Answered my own question!!
The solution is to set the stroke for the ColumnSeries to {noStroke}, which I defined like this:
    <mx:Stroke id="noStroke" color="0xFFFFFF" weight="0"/>
Note that if you define {noStroke} without a color property, black is used by default, which means that those columns that do appear show up in black stroke outline.
If there's a more elegant solution to the problem, please let me know...

Is it possible to filter a table for NULL values in a column? (11g)

I am using the out-of-the box table filtering provided by ADF Faces RC, but cannot figure out how to filter on Null value that are in the table.
I have tried "IS NULL" and "= NULL", but nothing works.
I have a backing bean that intercepts the filtered values before the filter is applied, and I can't set it there either.
Does anyone know how this is accomplished?

No, it is not. Worse, many people will view this in any old PDF viewer, most of which won't have overprint preview at all.
You need to send very clear instructions about this, with specific screen shots - or better, avoid tools and constructions that require it. Probably some wording about "need to view with suitable professional tools" will make the message more palatable.

Check for NULL values

Hi,
I have a table with columns a1, a2, a3, a4 and a5. The column a1 is the primary key for the table. I want to check if all the other columns except a1 have null values. How can I do that?
Thanks,
Machaan

For fun;
select a1,
       a2,
       a3,
       a4,
       a5,
       nvl2(a2, 0,1) + nvl2(a3, 0,1) + nvl2(a4, 0,1) + nvl2(a5, 0,1) num_nulls
from sample_data;
        A1         A2         A3         A4         A5 NUM_NULLS
         1          2                                           3
         2                                                      4
         3                                4                     3
         4                                4          4          2
         5                                           2          3
         6                    -2                                3
         7          1          2          3          4          0
         8         -1         -2         -3         -4          0
