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).

Cross Tab Report...Calculated Column shows NULL

Hi there
I have one calculated field which is based on some calculation when I run my report in Discoverer Desktop I can see the 0 in NULL values in all rows.
But when I run this report in Discoverer Plus/Discoverer Viewer it shows me Null for some values or some values I can see the zeros.
I have checked the WorkBooks options its all set to 0.0.
1)
Edit---> WorkSheet Properties ---CrossTab Format ---Show Null values as 0.0
2)
Tools---> Options---> Sheet--->Show Null values as 0.0
3)
I have settings in Pref.txt which means Some reports I want to see the NULL values...
Pref.txt
NullValue = "NULL"
Do you have any idea..
Thanks
ASIM

Well, I don't really have an idea what is happening, but i have a solution to hide nulls.
You can create an exception on the columns.
when column_name = Null then change the forecolor to match with the backcolor.
This will make the text and box of same color and will hide nulls.
Cheers :)

DBA_USERS showing null values in PASSWORD column

Hi,
We are running a select query from dba_users table as follows :
select username from dba_users
where to_char(expiry_date, 'DD-MON-YY') =
to_char(sysdate + &expire_day, 'DD-MON-YY')
and password not in ('EXTERNAL','account-locked')
and account_status <> 'LOCKED';
This query was running fine with 10g Version, but after Oracle was upgraded to 11G recently, above query does not return any rows.
Also, when we remove the condition "and password not in ('EXTERNAL','account-locked')", it works.
And the values for the PASSWORD column shows null.
Is this related to Oracle upgrade ?
Kindly help..
Thanks,
Jatin

I have the same behavior in my 11g db (I have nulls in password column too) as checking docs:
[url http://download.oracle.com/docs/cd/E11882_01/server.112/e24448/statviews_5081.htm#REFRN23302]Oracle® Database Reference 11g Release 2 (11.2) - DBA_USERS
I can see:
USER_USERS describes the current user. This view does not display the PASSWORD, PROFILE, PASSWORD_VERSIONS, EDITIONS_ENABLED, or AUTHENTICATION_TYPE columns....
PASSWORD VARCHAR2(30) This column is deprecated in favor of the AUTHENTICATION_TYPE columnIt seems you need to get this info from somewhere else.

'Show Null Values as' variables not replaced

I need the null values to display as small as possible so there is an image in my image repository, 1x1px, transparent, that I wanted to display in these null places, but when I inserted something like <img src="&COMPANY_IMAGES.null.gif"> or <img src="#COMPANY_IMAGES#null.gif">, the COMPANY_IMAGES was not replaced with the usual long call, it was just like inserted in the 'Show Null Values as' field.
I have workarounds
1) use a static image, that is publicly available - making the app's appearance dependant on that publicly available image.
2) select columns with nvl(NULLABLE_COL, '<img src="#COMPANY_IMAGES#null.gif">'), which is just a thing, that could be easily forgotten in some place and makes the query even more obscure than it already is.
I really like neither of them. Is there some other way to call COMPANY_IMAGES in that field or is it just a place where isn't the substitution string available?

wow. you're right about that substitution not being made in that "Show Null Values as" field. i'll log that issue in a sec. you can work around the issue for now by simply doing that substitution yourself. so if you run this...
select :WORKSPACE_IMAGES FROM DUAL
...from your sqlWorkshop, you'll see that WORKSPACE_IMAGES is substituted with a call like...
wwv_flow_file_mgr.get_file?p_security_group_id=123456&p_fname=
...(where 123456 is my :WORKSPACE_ID). if you wanted to call an image called my_image.jpg in that "Show Null Values as" field, you could just enter the string...
wwv_flow_file_mgr.get_file?p_security_group_id=123456&p_fname=my_image.jpg
...right in there, and you'd find your images rendered correctly. the only thing to watch out for is the hard-coded :WORKSPACE_ID in your field. you'd have to mind at number if you deployed your app in a different workspace.
hope this helps,

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.

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

Show NULL values in an SQL query

Hi,
Please excuse my ignorance, but I am very green in Oracle.
I am trying to create a simple function in PHP to return a list of the entire table row in an Oracle DB, however no matter I do Oracle skipps the columns with NULL values, which means that I don't even get the number of the columns corect. The query is as simple as it can get:
SELECT * FROM table_name;
I've tried NVL, DECODE and god knows what else. Please give me a hand with this.
Cheers,
Pimmy

Once you can use ODBC it should be possible to use MySQL with HS:

Show null values as

Hi,
I am running Discoverer Plus 10.1.2.45.46c. We are running into some issues with the Show Null values as option under Tools/Options/Sheet tab. If you open an existing workbook that has this value set to NULL you can't change your output to show as ' ' for example.
Has anybody else ran into this ? Is there a work around ?
Thanks
Dennis

As per bug 4330751 - workbooks created in desktop with the option for nulls set to "" will display as NULL in plus. There is a new worksheet setting for nulls that you can modify in plus - Edit->Worksheet Properties->Crosstab/Table Format tab.
The pref.txt setting will be honored for new plus workbooks.

Limit SC showing Zero value in report SC per cost centre in SRM portal

Hi SRM Gurus,
On executing SC per cost centre report avaialble in SRM 5.0 Portal I am getting value of limit SC as zero. while in all other follow on documents i.e. PO and Invoice its displaying the value.
Is it due to the fact the for Limit Items we don't have any GR/confirmation i.e zero quantity? and the value column field has Sigma symbol on it. so maybe it is multiplying quantity with the value here?
Is this SAP SRM standard for limit items to show zero value in this report ?
Please let me know. Thanks for the help.
Regards,
Varun Dhawan.

SRM experts please help in this regard. Any insights on LIMIT Shopping carts??

I've created a cross-tab report but I will like for the report to list the rows will null values as well as the rows with values. I need to do this because I cannot create one cross-tab with all of the necessary fields, so Iu2019ve created 3 cross-tabs and placed them side by side. Or is it possible to link the cross-tabs.

What I've done in the past is create a new formula for your "value" field similar to this and put it in your cross-tab:if {original value field} is "" then [0] else {original value field}the purpose is to create a record value (e.g. 0) where there is no record. I hope that this helps.

Implicit Fact column creating problem to the reports.

Hi Friends,
I have two reports from same subject area from two different facts F1 & F2.
I have created one implicit column, as it is unable to judge from which fact it needs to build the query. So, it is genarting query from fact F1.
I have created one logical column in the fact and marked it as Implict column in presnenation layer.( as we the process)
But the problem is, for both the reports it is using same implicit column and it is generating the query with only one fact F1.
It is excluding the other fact F2.
One report it shoud use Fact1 and other report it should use Fact2.
PLease hep me in regarding this,
Thanks & Regards,

Kalyan J VFrom my understanding, implicit fact column's are set a subject area level and not dimension/fact level. So the fact table you have set for implicit fact will be used in both the reports. Why dont you just drag the second fact into the report and hide it, if you are not trying to use the fact 1 that is setup as implicit fact?

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?

Use Indicator variables and let me know if it solves your problem.

The name in getAttributre doesnt match the name in setAttribute.
Note "subject[0]" is a string containing 10 chars, "subject" is a string containing 7 chars.
Here is your code:
session.setAttribute("subject",subject);
String sub1=(String) session.getAttribute("subject[0]");

Fact column shows null values in report
