Report shows a string "null" for null values.

Hello

I am new to BI Publisher and creating a report in the BI Publisher. In the game of null values, report prints as "null". I checked the query, it gives data blank (empty value) for null values. But in the report, it comes as value 'null' (string "null"). I need to show the report in the form of empty data for null values. Can you please help me to find the solution for this?

Thank you much in advance.

Report - show no redundant numbers
Hello, I was expecting if someone could help me with a report that I built on APEX.

The report consist of three columns of information.

PERMIT_NUM
DATE
STATUS

The PERMIT_NUM column contains redundant numbers, because the State passes of inprogress to complete.
example:
permit num: status date
12 inprogress 7-SEP-08

permit num: status date
Complete 12 10 - sep - 08

I would like to ask inprogress, without show inprogress if the number of permits is the same and complete.
If the query displays only the inprogress.

Please help, im stuck, you may not know.
Hello

You will need to join the table to itself to check records with the same value of PERMIT_NUM.

Maybe:
```
SELECT A.PERMIT_NUM,
A.DATE,
A.STATUS
FROM MYTABLE A
WHERE A.STATUS = 'Complete'
OR NOT EXISTS (SELECT 1 FROM MYTABLE WHERE PERMIT_NUM = A.PERMIT_NUM AND STATUS = 'inprogress')
```
or
```
SELECT A.PERMIT_NUM,
A.DATE,
A.STATUS
FROM MYTABLE A
WHERE A.DATE = (SELECT MAX(DATE) FROM MYTABLE WHERE PERMIT_NUM = A.PERMIT_NUM)
```
The first would show all records and all others who do not have a folder "full".

The second would show the last disk for each value PERMIT_NUM the field of DATE - it would count on this area that contain different values for each step, so only it would work dates are different or if the field include a portion of the time.

Sorting and null for currency values in a report
All,
I think this should be easy, and I just missed something obvious.
I have an APEX 3.2.1 standard report that includes a column with a monetary value in it. I want the column to display the UK pound sign to be able to sort and display NULL values, as appropriate.
The question I have is that I can't find a way to reach all 3 in a medium satisfctory. As I see the options would be:

(1) in the SQL for the report, concat the pound sign in the required column, for example SELECT "£". amount OF the...
The problem is that it makes this field a CHAR field, so sorting is not sort of the same way as for a numeric field.

(2) use the format FML999 number... etc in the column attribute.
The problem with this is that it is a multi-country database, and the default currency unit is the value of the U.S. dollar.

(3) expression box to use HTML code in the column attribute to display £#COL #.
It fills the pound sign and keep the number format, but unfortunately a null value is displayed as a sign of pounds with no number. I do not see how so he can leave this value in the report as completely empty.

As I said, I'm sure I missed obvious soemthing. If someone can identify how to achieve this it would be much appreciated.

Kind regards
Jon.

The NLS currency symbol can be changed on the fly if you have a few ways to identify the location/preference of the user: {: identifier of the thread = 990848} (ignore the last post)

However, it probably doesn't make sense to do - ≠ £100 $100 (at least I hope not!) - unless there is some sort of conversion occurring in the report? Is there a currency stored and the amount?

Use 2 columns, one for the amount and one for the money, with a switch to include or exclude it if necessary:
```
select
          ename
        , comm amount
        , nvl2(comm, '£', null) currency
from
          emp
where
          job in ('SALESMAN', 'MANAGER')

ENAME      AMOUNT                 CURRENCY
---------- ---------------------- --------------------------------
ALLEN      300                    £
WARD       500                    £
JONES
MARTIN     1400                   £

Then use the two columns in the Expression of the amount of HTML:
```

Report tamplate custom: null values is rendered in white-tank
Greetings!

In my sample report I used the substitution of strings with format #ENAME # inside the < b > - tags. In the report under the "page layout" and paging attributes value for 'See the Null values as' is left white, so that null values are not rendered in the tag. Still in the html code, they are rednered to the ' & nbsp;' html whitespace. "

As arbitrarily as if turned column formatting to 'Standard report column' or 'View as Text (excape special characters)', if "strip HTML Tags" is selected or not.

Does anyone know how this can be solved?

Thanks for the help, best regards,.

Hi College!

My problem is this: when a whole line of html contains no value, it will be displayed to zero a hight - what I died for reasons of effectiveness of room. But when all the empty cells contain a white tank, I have some excessive areas in the picture.

A record data is displayed above the rows of trees, the last of them extending over the entire table. For this last line, I bypassed conditional select wich
```
    (...)
case when qmmUserNote is not null then
'Anmerkung: ' || qmmUserNote || ''
else null end                                             USERNOTE
```
So if it is empty, the whole line is not at all, althou it is an invalid space character in markup (after the - end tag). Works fine in Firefox, but Internet Explorer moves this space-char excessive to the top of the table, so that for each empty line, it appears an extra row of white at the top.

Same result when I write:
```
 (...)
else '' end
```
So to get around this extra white, I changed this last output in:
```
     case when qmmUserNote is not null then
'Anmerkung: ' || qmmUserNote || ''
else '' end                                             USERNOTE
```
, which means that html tags most are transferred to the side of data operation, away from the model, that is simply not so nice and everything a bit messy.
I suggest you spend the conditional processing in the model using models of conditional line based on PL/SQL expressions, as well as the last row is not out if qmmUserNote is null.

Inline when checking for null values
Hi, I'm currently stuck with a problem regarding the verification of null values. The problem revolves around an address line, where I want to display values such as roadname, number, zip code etc. The address line is supposed to be on a single line, no carriage return. The address line must be prepared for null values, if we say it have no house number. That's why I am attaching these tags with an if statement:

& lt;if@inline:HOUSENUMBER!= "? & gt; & lt;? HOUSE number? & gt; & lt;? end if? & gt;

But when I try this in my report, it seems that @inline BEEP do not take into account the signal no one checking the logical expression and always showing the content enclosed in the case. When I remove @inline, it works as it should, but there is a carriage return when the value is zero.

Does anybody know a solution for this?

Thanks in advance

Kim
Hi Kim

Hmmmm works for me. I noticed that you have a lack? just before the if. You can also try @inlines, it's a subtle difference in functionality.

Even without the FI doesn't text collapse left anyway?

Ignoring the Null value or 0 for an average of

Hello
I don't code in Java, so I'm having a problem with a form.
We have a form of training that adds the total of the sides and then is supposed to understand on average. My problem is that the provided average is based on the average function canned for the field, so it's the calculation of all the fields, including those who have either a Null value or a zero. Can someone help me with this please?
By the way. If the N.O. is checked, the coast is n/a.
There are also five sections that will total all the sides and will need an average of these totals.
Thanks in advance.
Tom
Screenshot taken: 15/03/2013-21:09

Here's a generic function to calculate the average of a group of non-empty fields.

This function takes two parameters: an array of domain names at average and a Boolean value specifying if the function should return an empty string if the result was zero.

function averageFields (fields, blankIfZero) {}

var total = 0;

var n = 0;

for (var i in fields) {}

var f = this.getField (fields [i]);

v var = f.valueAsString;

If {(v)

total += (+ v);

n ++ ;

}

}

var returnValue = (n == 0)? ' ': total/n;

If (blankIfZero & returnValue = 0) returnValue = "";

return returnValue;

}

You can set this function at the level of the document, and then call it as follows (starting a custom calculation script, in this case):

Event.Value = averageFields (["field1", "Field2", "Field3"], false);

Displaying a string instead of the "null" value in the columns of answers
Hi, is it possible to display a string (e.g. "no data") in responses instead a NULL value in a column of a table or a PivotTable? I read everything by using the formula in the column section in the answers, but I do not understand what expression should be used... could you help me?

Is this kind of possible substitution only in the web interface of answers, or still in BI Admin meta - data? I would be very interested to recognize from analysis UDML in metadata,
Thanks in advance!
You must do this in the business model and the Mapping layer

Go to the properties of the column

1. in general tab, you have "use existing columns of logic as a source.
Select this check box. Click the period (...)
In the formula for the column, you can add the condition of ifnull
In this col formula editor, you can choose the logical columns.

2. on the Data Type tab, you have the maps and logical sources
Here too you can achieve.
In this col formula editor, you can choose physical columns.

NPE for rows with null values in the table of the adv
I created the table adv, 2 columns, equipped with two text fields. Initially the col2 is empty,
say that the structure is as follows:
```
              col1          col2
Hdr         Question    Answer
row1       abc           zxc
row2       pdd           null (user doesnt enter anything)
row3       zxc            lkj

APPLYBUTTON
```
When the user clicks on apply button I want to update these values in the table.

I don't know how to do that, but that's what I'm trying to do. Please guide me the right way if its wrong.

in LICS, I took the APPLYBUTTON action, got all lines of the object corresponding to the view, consulted with everyrow and I'm checking if there are values in the fields in the table, if the value zero, are simply print null. (we would not update on this line). . I could get o the part update, due to null pointer exception
I get on the row line null pointer exception [1].getAttribute("Answer") for row2, it prints the value of row1 however.

Here is the code I wrote:
Set of rows from the rowset = (RowSet) vo.getRowSet ();
Rank rank [] = vo.getAllRowsInRange ();
System.out.println ("row.length" + row.length);
for (int i = 0; i < row.length; i ++) {}
String question = row.getAttribute("Question").toString ();
String response = row [i].getAttribute("Answer").toString ();
If (question! = null & &!("".)) Equals (question. Trim()))
{
System.out.println ("Question line" + i + "-" + question);
}
on the other
{
System.out.println ("Question line" + i + "is null");
}

If (response! = null & &!("".)) Equals (Answer.Trim ()))
{
System.out.println ("Response line" + i + "-" + response);
}
on the other
{
System.out.println ("Response line" + i + "is null");
}

Why the NPE survey code, I'm checking for null value and you want to print the value null in the logfile... I can not to getAttribute() on the null field, why can not just give me null in the variable I'm assigning to?

You can guide me what approach to take, if it is not correct.
I must examine DataDictionary and collect data there?
Thanks in advance.
Hello

handle the exception of null on these two statements like this pointer

String question = "";
String response = "";

Try
{
question = row.getAttribute("Question").toString ();
}
catch (NullPointerException e)
{
question = "";
}

Try
{
answer = row.getAttribute("Answer").toString ();
}
catch (NullPointerException e)
{
response = "";
}

Si ( !("". Equals (question. Trim()))
{
System.out.println ("Question line" + i + "-" + question);
}
on the other
{
System.out.println ("Question line" + i + "is null");
}

Si ( !("". Equals (Answer.Trim ()))
{
System.out.println ("Response line" + i + "-" + response);
}
on the other

NULL values for some elements of the XML reading tree

I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control). Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected. I have checked some obvious things like misspelling the names of keys, but have not yet find the problem. Anyone who has debugged similar questions - what else could cause this?

Example XML:
```
    1.0.0.0
    1000
    MyAppsName
    
        
            1000
            userDefined
            StructName
        
    
```
And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

In DataManager.hpp:
```
QVariant mCustomDataStructsTopLevel;
QVariantMap mCustomDataStructsTopLevelMap;
```
In DataManager.cpp:
```
mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();

qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
```
OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on. I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls. DOH!

BEEP graphical report shows zero when data are missing in EBS instead of null

Bug 18270934 : PUBLISHER PRINTS NULL VALUES such as ZERO IN a TABLE

Kevin

test for the null value to IN request (null, 'a ', ' b', 'c')

Hello
Oracle 10.2.0.4
I think the following query is incorrect, in my opinion. (there is an index on the collar, but NULL values are ignored?
SELECT COUNT (*) < table > where col in (null, 'a ', ' b', 'c')
It works (no errors) and forth fast enough.
However, I think the correct query would
SELECT COUNT (*) < table > where IS NULL or neck neck ('a', 'b', 'c')
It takes a lot of time. As I see it, he performs a table scan for part of the value NULL and use the index for the rest, as the index cannot be used for NULL values.
I would appreicate an explanation on this matter, particularly why Oracle accepts the first query "where col in (null, 'a ', ' b', 'c')" without any problem.
Thank you

A null value is not equal to what whatsoever, not even another null value. This is consistent with the definition of the ANSI. For your first request is not what you think it does, even if it is not syntactically incorrect.

The second query is correct. If you want to use an index, you must create a bitmap index (which requires Enterprise Edition licenses), because they do not include the values NULL, unlike B * tree index.

REGEXP_SUBSTR for the list delimited by commas with null values

Hello

I have a column that stores a list of values comma-delimited. Some of these values in the list may be null. I'm having some trouble trying to extract the values using the REGEXP_SUBSTR function when null values are present. Here are two things I've tried:

SELECT
   REGEXP_SUBSTR (val, '[^,]*', 1, 1) pos1
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 2) pos2
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 3) pos3
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 4) pos4
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 5) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

POS P POS P P
--- - --- - -
AAA   BBB

SELECT
   REGEXP_SUBSTR (val, '[^,]+', 1, 1) pos1
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 2) pos2
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 3) pos3
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 4) pos4
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 5) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

POS POS POS POS P
--- --- --- --- -
AAA BBB DDD FFF

As you can see that neither calls work correctly. Anyone know how to change the regular expression pattern to handle null values? I tried various other models but could not get anyone to work in all cases.

Thank you

Hi, Martin,.

That's what you want:

SELECT
   RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 1), ',') pos1
  ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 2), ',') pos2
  ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 3), ',') pos3
  ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 4), ',') pos4
  ,RTRIM (REGEXP_SUBSTR (val || ','
                      , '[^,]*,', 1, 5), ',') pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

The query above works in Oracle 10 or 11, but in Oracle 11, you can also do it with only REGEXP_SUBSTR, without using RTRIM:

SELECT
   REGEXP_SUBSTR (val, '([^,]*),|$', 1, 1, NULL, 1) pos1
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 2, NULL, 1) pos2
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 3, NULL, 1) pos3
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 4, NULL, 1) pos4
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 5, NULL, 1) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

The problem with your first request was that he was looking for sub channels of 0 or more non-virgules. There was as a substring. consisting of 3 characters starting at position 1, he returned "AAA", as expected. Then there was an another substring, the 0 characters, starting at position 4, so it returned NULL. Then, there was a substring of 3 characters starting at position 5, so he returned 'BBB '.

The problem with your 2nd request was that he was looking for 1 or more non-virgules. 'DDD' is the 3rd this substring.
