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.

'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,

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.

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]");

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.

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:

What concerns the licenses: We are not referring to transparent gateways but to heterogenous services (generic connectivity) which come free with the DB:

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).

Error in Open Dataset. Application server file shows null value .

Dear Gurus,
As with my previous problem, I am now getting value from SAP Directory in AL11. But problem is-
1. When I try to get Quantity or Currency field, it shows runtime error while uploading in App. Server. So, I used Char data type variable to store currency field and concatenate these in a string type variable.
LOOP AT it_mseg INTO wa.
move it_mseg-erfmg to amount. " amount is a char type variable.
CONCATENATE it_mseg-mblnr it_mseg-mjahr it_mseg-matnr amount it_mseg-werks it_mseg-lgort INTO ld_string.
TRANSFER ld_string to filename.
But I am getting only 0 for all the records. If I directly transfer wa to filename, it shows values. But when i am passing string, all value shows 0. Plz give me solution.
Thanks,
With regards,
Tripod.

Hi,
use
WRITE it_mseg-erfmg to amount.
or, assuming that the currency is WW_WAERS,
WRITE it_mseg-erfmg CURRENCY WW_WAERS to amount.

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 :)
