Derived column dot showing in CSV

Hi, I have a derived column.
When I unabled the report so it downloads the data into a spreadsheet,
I see that it's showing all the column headings but not tha value.
Is there a way to fix it so it also shows the values of the derived columns in CSV?
Thanks,

Hi,
I had a similar problem. As I understand it, the csv export function re-runs the SQL statement and produces the output based on that rather than the contents of your report (which is why, for instance, you get all of the data even though your report may be paginated).
The only solution, which I had to use, was to change the SQL statement to include the derived values rather than create them on the report definition.
Regards,
Andy

Create a derived column based on a value within the file name

I am importing a CSV file which is easy enough, but I have an issue where I need to manufacture a couple of column values based on the filename of the input. So this same process will import different types of records to the same table in sql server.
I need to pull out the record code from the file name.
For instance, say I can use the same package to input two different CSV files. One is named Input_M02_Data.csv and one named Input_B15_Data.csv. I need to create a derrived column and store the record code there (i.e.: M02 or B15) based
on which file it came out of.
fyi-
I also need to create a second column for Dept based off of the file name as well. M02 is dept 45 and B15 is dept 99 which I also need to insert into this table when I import the data from the .csv file.
Any help is greatly appreciated!

Hi Jason,
According to your description, you want to add two derived columns based on the file name to also insert into table. One stores the value between two “_” within file name, another stores the department based on that column.
If in this scenario, we can add a variable FileName that stores the filename, then add the two variables as derived columns like below in the Derived Column Transformation:
Name:
SUBSTRING(@[User::FileName],FINDSTRING(@[User::FileName],"_",1)+1,FINDSTRING(@[User::FileName],"_",2)-(FINDSTRING(@[User::FileName],"_",1)+1))
Dept:
@[User::Name] =="M02"?"dept 45":@[User::Name] =="B15"?"dept 99":"dept 00"
The following screenshot is for your reference:

Output a derived column to a flatfile destination

I'm a newbie. My source is a sql server table. Then I dropped a derived column icon. And finally a flatfile destination.
When I open the flatfile destination, it does show the new column as 'Derived Column 1' in the Available Input Columns, but it's not shown in the Available Destination Columns.
How do I add it to the Available Destination Columns?

I had to open the flat file connection manager window and manually add a new column.

Problem with derived column

Hi friends,
[Reports 6i - 6.0.8.20.1 & DB 9.2.0.8 ]
I have problems in one report to rerieve the value of a column in my Query1 in a derived column.
Let's say that we have a query (Q1) that obtain the departments of a company.
And a second query that obtain certain data for each department of Q1 and (this is important) we can't (due to others requirements) use a "link" to join the querys.
So my idea was to create a formula column (FC1) in Q1 where the departement is stored... and, out of the query, create a derived column that would have the value of FC1.
Then ... in design model... I'll have 2 repeating frames... one based on Q1 and other based on Q2..
Q1 Frame is ok and shows all departments... but... Q2 repeating... only shows values for 1 department... So my derived column seems not to change when the value of FC1 changes...
Any ideas?
Thanks,
Jose

If your query1 is something like
SELECT ...
d.deptno,
FROM
...dept d
WHERE ...
and you want to do query2
SELECT ...
FROM ...
for all departments but then split the output on display by department.
I'd go with the suggestion from the other poster above:
Do your query1 as
SELECT ...Query1Fields,
Query2Fields
FROM Query1Tables, (put query2 here) q2
where q2.deptno = dept.deptno -- or whatever the conditions are
Or use
WITH q2 AS (put query2 here)
SELECT ...Query1Fields,
Query2Fields
FROM Query1Tables, q2
where q2.deptno = dept.deptno -- or whatever the conditions are
That second format should ensure that query2 is done as one whole unit.
Then in the data model drag and drop the query2fields outside the query1 group to form a new group below it. Then in the layout you have a repeating group based on the query1 group and within it a repeating group based on the new "query2" group.

Finding correlation using derived columns?

I want to use the aggregate CORR_S function which take two numerical columns and output the correlation between them. Assuming I have the table:
Employee(name, gender, salary) where I want to create two derived columns, how would I do it?
Like,
SELECT CORR_S(
SELECT salary
FROM employees
WHERE salary < 10000,
SELECT salary
FROM employees
WHERE salary > 10000
) as correlation
FROM employees
It will find the correlation between salary's less than $10,000 in one column and salary's more than $10,000 in another column. Of course, I get an error when running the query. It's no problem if I use CORR_S(salary, salary) but I want to use derived columns, is it possible? Or, will I need to create a new table view with two new columns CORR_S(lowSalary, highSalary)?
Thanks.

It may be correct sql query, but statistically ( i mean here the OP question, or at least how i interpret it) it is nonsense.
Clearly , correlation show how good distribution of one set of items corresponds to another set, so the order of item in the itemset does matter. Consider
SQL> WITH t AS (
2          SELECT 1 id1, 10 id2, 30 id3 FROM dual UNION ALL
3          SELECT 2 , 20 , 10 FROM dual UNION ALL
4          SELECT 3 , 30 , 20 FROM dual )
5 SELECT corr_s(id1,id2), corr_s(id1,id3)
6 FROM t
7 /
CORR_S(ID1,ID2) CORR_S(ID1,ID3)
              1             -.5So, it would make sense to calculate correlation between salary and hiredate, salary and department number, salary and employee name's length, whatever, but how can be correlated salary less 10k to salary more than 10k - i can't understand it. They are not in the same set, but in two different sets ( while one can have either more 10k or less 10k, but not both) and relation between these two sets is not given by OP.

Derived column containing radio button

Hi,
I have a derived column in a report. In the field HTML Expression, I have the following HTML code:
<INPUT TYPE="radio" NAME="radTypeSelectionStatut"><
<INPUT TYPE="radio" NAME="radTypeSelectionStatut" CHECKED>=
<INPUT TYPE="radio" NAME="radTypeSelectionStatut">>
<INPUT TYPE="test" SIZE="5" VALUE="#VAL_STATT_SELCT#">
The page displays well but when I click on a tab, I have the error "HTTP 404 ". I have two levels of tabs and I have no problem to click on a parent tab, just on the tabs on the same level. If I don't show the column, I don't have the problem.
Lisandre

Hi,
The radio buttons are not related to the database. It is possible to take the value with code later. The only code I have at the moment is what I wrote on my first post. You can check the application :
user : test
password : test
http://htmldb.oracle.com/pls/otn/f?p=38145:16:8894427558050515715::NO:::
In the parent tab "Règles d'affaires", in the tab "Paramètres", there are radio group buttons. If you click on another tab (not a parent tab), the page don't show up. But clicking on a parent tab is ok. The tabs under the parent tab "Règles d'affaires" are all fonctional when I don't show radio group buttons.

Derived column source

I have a report based on a SQL query. In this query I have some IDs which are foreign keys from other tables. I want to hide these IDs and show the names from the IDs primary table. In oracle reports I can show this as a formula column with a source as a pl/sql function. Can this be done in htmldb with derived columns, if yes where I should write the pl/sql expression?
I know I can do this by joining the table in the main query , but eager to know the other way is possible or not?
Recently no one answering any of my questions . Is there anything wrong I am doing? or am I being too silly. I am very new to htmldb please help
George

George - The most efficient SQL for your report would join all required tables and return the data you want to show. You could write a PL/SQL function to decode those foreign key IDs but that's kind of cheating (and slow).
About no on answering your questions recently, I found that:
Nov 3 - Carl gave a full response.
Nov 5 - You asked a question of a person who last posted on that thread in October 2003.
Nov 6 - You got a full response.
Nov 7 - (server topic) You got a full response.
Nov 7 - (wizards topic) Jes responded, you asked a follow-up, he hasn't gotten back to you but I don't really understand your question.
Nov 7 - (fresh install topic) Your statements imply that there is no longer a problem.
Nov 8 - (htmldb 2.0 Install help) No one responded. You should have bumped that.
Nov 9 - You asked Holger a question in response to something he posted in February 2004.
Nov 9 - (htmldb 2.0 with Oracle AS 10G) You got a full response from Joel.
Nov 11 - Jes has not responded back yet. Bump it.
Nov 14 - (Text not wrapping). No response, bump it.
Nov 21 - (Yesterday) It hasn't been long enough to be concerned about no response, IMO.
So there are a few posts that fell by the wayside, but I wouldn't say that you're being ignored. It might help if you provided more information in your initial postings so people don't have to ask you for more information. We do hope you'll stick around and keep asking questions when you need help.

Truncation in derived column

Hi guys, I have got a table with a column (wrongfile nvarchar (300)) and a package with a Derived Column in this way:
I I had to ignore the truncation because it always retrieved "truncation occurred..." but now if I see the table the column wrongfile is empty and I am wondering why by the way that the column in the csv file it less than 100 characters..

Change your expression to cast the variable to Unicode:
(DT_WSTR, 300) @[User::NBFile]
It appears that if you create a column using derived column it gets the length from the variable. So if it is empty when you create the component, SQL Server will create a 0 length output.

Report Attributes: Add column link and derived column

On the Report Attributes page (4000:420), under the Tasks list on the right side of the page, there are 2 links, "Add column link" and "Add derived column". This is the first time I am noticing them.
The usage is clear, they add columns to the report to function either as a drill-thru link column or just a read-only derived field.
Doing it this way does NOT modify the source query for the report region.
Is there any benefit to using this feature versus adding a "null column_link" or "null derived_col" columns to my source query then setting attributes for those columns?
Thanks

Well, one disadvantage I can see of using the 'Add Column link' is that if I have more than 1 of such columns, they all show up as '[column link]' on the Report Attributes page with no way to tell what the underlying links are. Instead, if I were to manually add these dummy columns to my query itself, I would give them meaningful column aliases that indicated where they link to.
Suggestion: Maybe a tooltip could be added to the Report Attributes page for such columns which indicate what the underlying link is without actually going to the Edit page for that column.
Thanks

Derived column without trigger

Hello eveyone,
I was wondering if anyone can tell me if it is possible to have a computed column on a Oracle Table (like in Excel formula's). Let's suppose this example:
CREATE TABLE MYTABLE
BIRHTDAY DATE,
AGE NUMBER(10,4) (= (SYSDATE-BIRHTDAY) / 365) )
);This is an example; I know this does not make any sense. But that's the idea. I know I can have a column which can be updated through triggers (after insert/update of a given columns), or I can also create a view.
But is there any way to create a derived column with its logica defined within the create table statement?
Thanks for your help,
O.

Hi,
If yoo are on a lower version then one option you have is a view.
Keep your data as it is, write a view which will do the calculation and show you the result.
For example(a very basic one)
drop table test;
create table test (sal number, comm number);
alter table test add (emp_id number);
insert into test values (1,2,1);
insert into test values (3,2,2);
insert into test values (4,1,3);
insert into test values (5,2,4);
commit;
create or replace view v_test as select emp_id,sal,comm,sal+comm total from test;
select * from v_test;Cheers!!!

Derived Column as a prompt

Hi All,
I have a derived colum which displays the COUNT(Activity) in the last 12 months....to achieve this I added the below mentioned filter....
Activity."Completed Date" >= TimestampAdd(SQL_TSI_MONTH,-12,CURRENT_DATE)
Now my query is can we have this delivered column which shows last one year data as a prompt and make it more dynamic....i.e user will be given an option to select a date range to display the records. So is this possible ??? Can we modify the filter to make it generalised and add the same column as a prompt ?? Please give your valuable suggestions.
Thanks
Natraj

Hi Venky,
when I give it as prompt with "In between" option, I will get the prompts with calendar icon. My question is, this will be ok if we try to look for a data within the last one year as our timestamp condition looks for data within last one year only.(Please see the timestamp condition, we have used 12 there in the middle)
If I try to look for a date range in the lat two years where as my timestamp condition only looks for last 12 months....this will not work rite? How can I generalize this prompt ????
Thanks
Natraj

Drill down in Table or Pivot for derived column

Hi All,
I have a requirement like Top 5 products should show the product names and remaining should go to *'Others'*. I achieved it by using Rank function and case when.
ex: case when rank(product) <=5 then product else 'Others' end
Now the problem is, I am not getting the Drill option for this column. When I use product column without case when or case when on same column like
case when product = 'xyz' then 'abc' else product end. In this case drill is working.
Can anybody suggest me to get the drill on the derived columns.
Thanks in advance

A similar thread was recently talked about here:
In OBIEE charts, how do you make drill downs work on custom formulas?
With a calculated column, you need to make sure the source query and destination query have the EXACT same formula and the same name for the field. If it is not 100% identical, it may not work correctly. (I typically use the NAVIGATE function to get to the second query rather than the Drill function.)
Now in some cases, if you try to create a second drill down query with more details in it, the original formula doesn't work the way you want it to. The calculated formulas have to make sense in both source query and destination query in order to work properly. If you have a ranking of the Top 5 Products in the source query, the destination query also has to have the same ranking of Top 5 products in order to work. If you add more fields into the destination query (e.g., adding on product attributes, or # of records associated with that product name etc.), then sometimes the ranking / aggregation in the destination doesn't add up the same way. This causes the system to think that the formulas are different and prevents the drill down.
I managed to get around this by having a 3rd query in between the original summary view and the detailed data view. So the sequence would be (for example):
- Dashboard based summary query (including the calculated ranked product names formula)
- drill down into virtually identical query (add on one slight bit of difference here, for example adding on a second Product Name field ... not a calculated version, but the actual name). Create a drill down this time by clicking on the regular Product Name field (don't drill down on the custom formula)
- final detailed drill-down query
You can format this intermediary drill down query to explain to users that they need to click a second time.
It's not ideal, but it should work. Hope this helps.

How to cast a column of a derived column in a view to NULL

I have a derived column in my view and this column by default is picked up as not null.
I want to cast it to null how can i do it ?
Actual column
column1 varchar(3) not null
Expected column
column1 varchar(3) null
Mudassar

Shridar I havent defined it but the derived column has been picked up as not null which is strange
CREATE VIEW test
AS
SELECT
CASE
WHEN COMPANY_SIZE IS NULL then 'a'
ELSE 'b'
END AS
column1 ----- added derived column identifier
,[Company_Size] AS [CompanySize]
FROM xyz

How can I customise Thunderbird message columns to show sender raw address (not display name) and the "Received for" email address that was used to reach me?

I find it increasingly important to be able to see a sender's actual email address rather than just display name, as they usually don't show a company name - which a domain always would. Is there a way to customise settings/write a script/tweak files to add raw email & domain name columns? When dealing with a number of people at the same company it is hard to order or glance through a list of emails to find them. I also know 2 people with the same name at different companies and it is impossible to distinguish!
Secondly, as a related column addition, since a number of email aliases reach me it would be useful to have a column to show the "Received..for" part of the message source which reveals the actual email used in the To/CC/BCC which led to me. Again can this be tweaked or scripted?
I have programming experience but have not made add-ons and would be open to a suggestion which involves creating a custom add-on if adding columns with custom values is possible that way.
Best Regards,
Drew

Extended message headers can be searched from Edit/Find/Search Messages, or the folder context menu, by adding custom headers to the search criteria. So, you might be able to create a search on specific properties of a message.
The method of adding custom headers to searches is the same as the one described here for filters:

How to add a column that shows the difference of two metrics columns?

I created a pivot table with two metrics columns. One metrics column has the aggregation rule of 'Min', the other has 'Max'. Now I want to add a column to show the difference of these two metrics for each row. Is this possible? How to do it? Thank you in advance.

Use TimeStampdiff:
TIMESTAMPDIFF(SQL_TSI_HOUR, MIN(xxxx), MAX(xxx))
It's in the help file if you need more help.
