What is a Calculated Field?
Hi,
I have an assignment which requires me to use a 'calculated field' in a query.
Despite searching and looking in the books I have, I find no reference to the term.
I'm guessing that it may mean something like:-
WHERE CUSTOMER.CustomerID > 3 * min_orders
The " 3 * " being a calculated field.
Is this it? Or does it mean something else?
Many thanks for any assistance.
This question has nothing to do with the Installation forum....
Post this to the appropriate forum (Forms , Discoverer forum ..to name some).
Greetings...

Trouble with calculating fields. Can't select (check) fields. Also can't figure out what's wrong with a division field (percent) that I created. Keep getting the pop up that format of the field doesn't allow blah blah blah... Help!
1. Use the mouse to select the field and then press the space bar.
2. A null string is the same as zero. What is the result for division by zero? -
What is better to use a calculation field or to use stored procedure
Dear All
i want to know what is better to use a calculation field on oracle forms , or to do the calculation using a stored procedure at the data base level and fetch the results to the fields on the form
Best RegardsHello Mohannad
the stored procedure approach might be more readable and maintainable when the calculation gets complicated.
And it might be easier to reuse when it's needed in another part of your application.

What is advisable for complex calculation fields in ADF?
Hi,
I am using JDev 11.1.1.2.0 with ADF 11g.
I have a screen where user is going to select couple of LOVs. Based on this selection one of my "read only field" should get refreshed.
This field should actually do calculation based on the 2 fields and another column of a table.
So for such cases is it advisable to build a function and call this from a binding method OR there is a better way of displaying a calulated field.
NOTE:
1. using the expression on a transient field is good if the calculated fields are available in the row. Here I have to fetch a value from a completely different table's column that is not present in the row. Again the value that will be fetched will depend on some other parameter which is available to me in the session
2. I am looking out to make this generic since these combination of fields are repeated in few of the screens and for same calculations
Kindly advice the ways in which this can be handled. And pls point the best from your view point.
Thanks in advance.Any quick suggestion?

DAX Dynamic Banding | Calculated Member based on Calculated Field
Good morning,
I've created a Power Pivot model that measures the blood glucose levels of clinical patients at specific times of the day. The requirement is that this metric, let's call it GlucoseLevel, is always averaged as it wouldn't make sense to sum up the values.
To meet this first requirement, I set the "Summarize By" property of the GlucoseLevel column to "Average".
The second requirement is to band the GlucoseLevel values so that groups of people can be measured by this band rather than by the individual measure values. I created a banding table in Excel and then imported it into the Power Pivot model. The banding table
has three columns (BandName, MinValue and MaxValue) and has the following values:
VERYLOW: Min Value = 0; Max Value = 3.99
OK: Min Value = 4; Max Value = 6.99
WARNING: Min Value = 7; Max Value = 10.99CRITICAL: Min Value = 11; Max Value = 30.00
It is at this point where I face my challenge. I have a GlucoseLevel measure and I have a banding table. Great. The challenge is: How do I create a calculated, dynamic
member that will look at my GlucoseLevel measure (at whatever level), do a lookup to my banding table, and then return the "BandName" column from the Banding table at that specific level? So to clarify what I mean by level: I want to be able
to view the bandings at Year level, or a Month level, or even at a week level. Then depending on what level I am at, my measure should have a Band associated to it.
I've tried to solve this issue in a couple of ways:
Attempt 1
Create a calculated column in my fact table that contains a nested IF statement to manually band my GlucoseLevel values. This works fine if I view my data at the lowest level of granularity, however
it does not work if I start looking at my data at the day, week, month etc. levels
Attempt 2
1.) Create a calculated field (not a calculated column) that averages my GlucoseLevel measure. This is cool because it will average my measure at whatever level I am viewing it at. Let's call
this field Bob...
2.) Band my measure Bob by creating another calculated field (called PatientBand). This field uses my banding table (described earlier) in conjunction with my calculated field Bob. This works perfectly, except for one big flaw: Excel sees this banding field
as a measure, and not as something that I can use as a column / row...
So my question is: Can I trick Excel into viewing my PatientBand calculated field as an attribute, and not as a measure? And if not, how do I get around this challenge? Here is the DAX formula that I used to create my second calculated field "PatientBand":
PatientBand:=CALCULATE(
VALUES (Bandings[BandName]);
FILTER (
Bandings;
Test[Bob] >= Bandings[MinValue]
&& Test[Bob] <= Bandings[MaxValue]
Thanks!So there are 2 ways that I can think of for doing that.
1) if you are only using MDX clients like Excel or Reporting services you can create a text based measure that returns the banding name. (Note that this sort of approach does not work at the moment with PowerView as it only displays numeric measures). This
would effectively let you show a label next to a reading as opposed to moving the reading under a given banding column.
Banding Name :=
CALCULATE (
VALUES ( Bands[BandName] ),
FILTER (
Bands,
[Average of GlucoseReading] >= Bands[BandMin]
&& [Average of GlucoseReading] <= Bands[BandMax]
&& NOT ( ISBLANK ( [Average of GlucoseReading] ) )
2) This next approach will show the results exactly as you had them in your sample screenshots. It just takes a slight bending of the DAX. I'm using a SUMX here, not because I want to sum anything, but because the "X" version of SUMX basically loops over
every row in the specified table and sums the expression in the second parameter. I have setup the second parameter so that it only returns a single value for the average if it is in the appropriate banding.
Banded Average:=IF (
HASONEVALUE ( Bands[BandName] ),
SUMX(
'Bands',
IF (
NOT ( ISBLANK ( [Average of GlucoseReading] ) )
&& [Average of GlucoseReading] >= MIN ( Bands[BandMin] )
&& [Average of GlucoseReading] <= MIN ( Bands[BandMax] ),
AVERAGE(Readings[GlucoseReading]),
BLANK()
,AVERAGE(Readings[GlucoseReading])

How to avoid duplications making a SUM calculated field
Hi, I'm trying to resolve this problem;
In my dataset (in a custom folder on the administrator) I have a list of tickets (with some attributes), and some of them are duplicated:
For example
Ticket_id Group_id Ticket_date Resource_name Ticket_status
5416 100000401 10/12/2007 7:10:31 am Mr. A 2
5416 100000401 9/1/2008 11:00:44 pm Mr. A 2
57381 100000401 27/12/2007 11:37:11 am Mr. A 2
57381 100000401 15/1/2008 9:33:12 am Mr. A 2
I want this duplication because I need it when I filter the dataset (using the Ticket_date) with two parameters:
Ticket_date between lower_limit_date and upper_limit_date
So, inside the report, regarding the ticket's number, if I take 2 records with the same ticket_id, I have a calculated field where I use the COUNT_DISTINCT and for each couple of tickets the count is always =1; in this way (inside the report) I have the following fields:
Group_id Count_tickects Resource_name
100000401 2 Mr. A This is OK !
Now, if I want to count how many tickets have the status = 2 (it means they are closed), I want to obtain 2 and NOT 4
I tried to use this calculation (Tickets Closed): SUM(CASE WHEN "Tickets Report #7 COMPL".Ticket Status Id = 2 THEN 1 ELSE 0 END)
but I always had the result of 4...and this not correct, because the tickets are only 2...
I also tried to use some analytic function using the OVER PARTITION BY, but I didn't obtain the correct result
In other words I'd like to achieve this:
Group_id Count_tickects Tickets Closed Resource_name
100000401 2 2 Mr.AAny help will be appreciated
AlexHi Rod, thanks for the reply,
I tried this calculation
COUNT_DISTINCT(CASE WHEN "Tickets Report #7 COMPL".Incident Status Id = 2 THEN 1 ELSE 0 END)
but it retrieves 1; it's right, because the result of the CASE statement is always 2 (the Ticket_status is always 2, 4 times), but this is not what I expect.
I'd like to calculate how many tickets are effectively opened (Ticket_status = 2) and this result is *2*, because I have only 2 ticket_id (5416 and 57381); the problem is that inside the data set these two ticket_id's are repeated two times.
I can't use "Hide Duplicate Rows" because this is only a layout solution (behind I have always the duplication); I can't use more than one aggregate function together because I have the error: Nested aggregate functions are not allowed...
To resolve this problem, I think, I have to restrict the records which are processed by the CASE statement; instead of pass to the calculation all four records (twice the ticket_id 5416 and twice the ticket_id 57381) I have to pass only two records (one the ticket_id 5416 and once the ticket_id 57381).....but how....???

Updatable property of Calculated Field in ViewObject does not work
Hello,
I have set the Updatable property of some ViewObject attributes to "while new".
In the page those attributes are shown as <af:inputListOfValues> components.
When creating a new row, those components properly appear as enabled and let me insert any values, since the row is new.
However, after a following commit, once the table in the page is refreshed, I still see some components enabled on the row I committed before. This only happens with attributes based on calculated fields, not with those based on real table fields, as if the "while new" property specified on the ViewObject calculated fields was ignored.
Do you know why? Is there a solution or work around?
Below are the ViewObject XML section and the af:component definition based on the attribute.

The question is what does this "require" flag do? We read the book of life (cl_htmlb_inputfield), and see that this flag only controls in the first instance a little red * that is rendered next to the input field. This is a pure visualization for the user of the page.
In addition you can ask that a check be done in the browser. This you can do with:
<htmlb:inputField id = "wander"
value = "E"
required = "TRUE"
doValidate="true" />
However, I would not serious recommend this. Now even if you user presses a cancel button, or link, or breadcrumb, or..., the check will still complain.
What we currectly do (and recommend), is to set the required flag on the <htmlb:<b>label</b>/> tag. And then do the actual checking on the server (must be done in anycase). If no value, or not correct, then also set the "invalid" flag, render out error message and redo page.

;Thank you,Hi,
So you know how to compute iptv for an individual row; the problem now is that you want to get a running total of iptv; is that it?
The problem there is that computing iptv requires an analytic function, and analytic functions can't be nested. To get the results of nesting f (g (x)), where f and g are analytic funtions, you have to compute g in a sub-query, and then use the results as the argument to f in a super-query.
Here's how to apply that to your situation:
WITH pivot_results AS
SELECT dis

You can get those results if you need them; just explain the rules that govern whether to display the values and when to display NULL.
The way you posted the sample data and results, and the quantity of sample data were all excellent; it really helped me find a solution. Thanks.
It would have also helped it you had explained how iptv is computed. Basically, iptv = 1000 * rep / tbld, right?
It looks like most of this code:
, DECODE(NVL ( SUM (may11_bld)
OVER (ORDER BY dis DESC)
, 0),0,0,ROUND(NVL(may11_rep, 0)*1000/ NVL ( SUM (may11_bld)
OVER (ORDER BY dis DESC)
, 0),2
)) AS may11_iptvwas a way of avoiding divide by 0 errors; it would have been helpful if you had explained that. -
I am using Acrobat XI Pro to build a fillable PDF form that can be used by customer who have Adobe Reader installed. I would like to create calculated fields, including the summation of two or more currency fields and the product of a currency and number field. The procedure for creating these escapes me. Does anyone have any insight?
Hi Gilad,
thankyou! - yes it seems though I was using the text tool when I had this problem: When I had created a few fields in the 'form edit' mode I then may later have added some normal 'comment' fields of text in the normal mode to highlight certain aspects on a form - I used the text tool thinking that was the right way in to add or edit text - I can now see I double click with the hand tool to still be able to access any text field I want to. Yay!
Many thanks for your kind assistance - I shall try this method later on a new form I was trying to create and which was giving me grief.
One last thing then: what is that default text field that can't be deleted actually for - why is it there? After all, a 'blank pdf' should surely be a truly blank pdf? Perhaps this is one for mighty Adobe....?
Kind Regards,
Pete -
Is it possible to edit a calculated field?
Is there a way to make a calculated field editable, overriding the calculation? My form table calculates HST on pay amounts. But not everyone charges HST so I'd like the user to be able to put $0 in the field manually. I can create an HST option box for each row but...that's a lot of "contriving" and not a practical solution ( I don't think). Is there an easier way to do this?
Thanks.The HST is variable because the form is used in all provinces.
In order to make it a no-brainer for the user, I have incorporated a check box on each row. If the check box is checked (value=1) then the HST calculation happens, otherwise the value=0. So this makes sense but doesn't work. I have adjusted the calculation order, doesn't make a difference.
Note: I've never used java but I used to work with Access databases so I do have an understanding of the language/logic, hopefully enough to help me learn this quickly.
Here is what I tried. HST option is the value of the checked Check box, which is "1". This code is returning the else value fine but otherwise isn't working and doesn't change when I toggle the Check box. Can you help me adjust this.
var h = this.getField("HSToption");
var f = this.getField("TOTALbeforeHST");
var g = this.getField("HSTPercentageValue");
if(h == 1){
event.value = f.value * g.value;
}else{
event.value = "0"; -
Using a "Sum" Calculated Field on a "Count" query column?
Here's my query using the Query Report Builder:
SELECT Col1, COUNT(Col1) AS Count_Column
FROM Table
GROUP BY Col1
It generates a report that lists all the values of column
"Col1" and how many times each value was used in Col1
For instance, if Col1 contained the value 'A' 12 times, 'B' 6
times, and 'C' 19 times, the report would generate this:
A - 12
B - 6
C - 19
What i need as a column footer is the total count of all the
values, which in this case 12+6+19=37
I am using a calculated field, setting the data type to
Double, the calcuation to Sum, and the perform calculation on to
'query.Count_Column'. Reset Field When is set to None.
When I run the report, it doubles the last number in the
report's Count column (19) and displays 38 on the page. I tested
this with another column and it doubled the last number in the
report as well.
How can I get it to properly Sum my Count_Column?Hi,
You need to check note 208366.1 which explains why totals can be blank. Without knowing the detail of you decode function it is hard to say what needs to be changed. Try putting a sum in front of the decode e.g.
sum(decode(period, 'Jan period', value, 0))
Hope that helps,

Retrival of calculated field from MDM

Any response is appreciable.

Hi,
I am using 9.0.2.39.1 and am having trouble summing up a calculated field. I have a crosstab layout like so:
MTD YTD CURRENT YR
2005 $ $ (decode function based on period)
2004 $ $ (decode function based on period)
2003 $ $ (decode function based on period)I put a grand total for MTD, YTD and Current YR, but it does not pick up the total sum for the Current Year calculated field. I then also tried a total just for the Current Year field, but it is just blank although that column has values for each row. Strangely the count/max..etc functions give me a value, just not sum. The calculation works perfectly just not the sum of it.
Any idea what I am doing wrong???Hi,

Using Calculated Field in Multi Value Field
In Siebel Application
Sales Order---> List
There is a field call "Sales Rep" which displays an "USERID" of Order Sales Team Mvg Applet.
But We want to display the Last Name and First Name (combined).We got the first and last name using calculated field (Active Full name).
When I try to get the full name, the system display the name based on the "Primary position", if I step out of the particular row and come back again
Is there any way to display the full name without step out any rows for Sales Rep fieldYour description is a little confusing. For performance reasons it is always best to set the use primary join on multi value links. This means that when multi value fields are displayed in applets they always show the primary by default. If you want to display something other than the primary what is your rational behind this and why not make the record you want to display the primary?

Bug in excel 2012/pivot/summation of calculated field
I have a calculated field (called TO) in a pivot
= if(time >= 600,1,0)
where time is a field.
I present it in 'values' with 'sum'. It shows correct values, but the sub-totals are wrong. I can send an example if you tell me where to...It's not a bug, it's a consequence of the way calculated fields work. You should read your formula as
=IF([subtotal of time in pivot table]>=600,1,0)
To calculate what you want, add a column with formulas to the source data of the pivot table.
