Own function in computation (Interactive Report)

Hello,
I have checked package WWV_FLOW_WORKSHEET_DIALOGUE (it's wrapped, so I've checked it only slightly) and table WWV_FLOW_WORKSHEET_COMPUTATION and found that those two objects are responsible for functions we can see/use at Compute panel of Interactive Report. I need to add my own function to computation but it's not possible. When I write MY_FUNCTION(A) in text box and try to apply then I receive message: "Invalid computation expression. MY_FUNCTION".
Is any way to add own function to be seen by Compute option in Interactive Report?
It's important that I don't want to use MY_FUNCTION in query defined in Region Source!
Thanks in advance,
Regards

Hi, just stumbled over your question and I happened to have the same problem.
It appears not to be possible to use your own functions although it would definitely be very nice.
However, I found a solution, but given that I already had my knuckles rapped once for mentioning them-who-must-not-be-named (anything starting with "WWV..." really), I am not going to post it here.
If you are still interested (and if you didn't fix it already for yourself), drop me a personal mail and I'll get back to you.
Needless to say, you should think long and hard before you make any modification in any WWV_ object and then decide that you shouldn't.
Regards,
Iulian

Compute function on interactive report

Hi Every 1,
I need some help with an interactive report i am trying to produce. What i am trying to do is use to compute function of an interactive report and add the actual count from a week (e.g. week 26) and add it to the forecast count of that week
The problem that i have is that they are on different rows
The table below shows that i am working with.
Week No|Forecast Count|Actual Count*
____26__|_______0______|___128231____
____26__|____180916____|______0______
____27__|_______0______|___164666____
____27__|____180916____|______0______
____28__|_______0______|___169302____

Thanks in advance
-N.S.N.O.

Is that the only way that this could be done?
I have tried to get the values on the same row but it has proved very very difficult.
The query i use to get the data is this:
select ROUND(TO_NUMBER(TO_CHAR(TO_DATE(rpad(con_add_td_hr, 10),'yyyy-mm-dd'),'ddd')-2)/7)+1 "Week No", 0, sum(cons_total) "Actual Count"
from corcon01_hour_totals
where db_name='CSAHEPA' and substr(con_add_td_hr,1,4)='2008' and CON_ADD_USER_ID not like '%LDL%'
group by ROUND(TO_NUMBER(TO_CHAR(TO_DATE(rpad(con_add_td_hr, 10),'yyyy-mm-dd'),'ddd')-2)/7)+1
UNION
select week_no, sum(manual_entry_cons)+sum(citedi_cons)"Forecast Data", 0
from concount_forecast_data
where db_name ='CSAHEPA' and year ='2008'
group by week_no
The problem that i have is that the 2 tables are not relate and do not have a matching table structure. For the actual count table i have to generate the week number using a data/hour column.
If you have any suggestions i would be very grateful.
Thanks

Interactive report from PL/SQL function

Hello All,
i have a pl/sql function that dynamically builds up a sql query and returns it as a varchar2.
when i create a new report then i can use this function in the report like
return f_function(param1,param2,v('APP_ID'), v('APP_SESSION'));
and this works fine.
Except i cannot create an interactive report for this function, because it is not allowed !!!!
So how can i use the function in an interactive report ?
Thanks in advance,
Marco

Marco,
Another rather extreme approach would be to go all the way and make your function pipelined (that is not only build but also execute the query) and then select from it in your interactive report.
The disadvantage here would be that any supplementary filtering would act on the result set of the function (not as an addition to the where clause of the original query). But if you can live with that...
The advantage would be that there's less fiddling with column headers.

Iulian

Interactive report on view based on pipelined table function.

Hi,
I want to build an Interactive Report on a view.
The view definition contains a select on a pipelined table function. I use context functionality to pass paramaters to the pipelined table function.
A plain select * from #my_view# in SqlPlus results in 121 different rows.
However, If I base my Interactive report on this view, I get 15 repeated rows (all the same).
Is it possible to use pipelined table functionality on an Interactive report? I can't seem to get it working.
If I use the following approach (http://rakeshjsr.blogspot.nl/2010/10/oracle-apex-interactive-report-based-on.html) I do get results, but I can't use this solution for a reason that's not relevant.

Hello,
Is it possible to use pipelined table functionality on an Interactive report? I can't seem to get it working. I have used it in one instance and it works fine. However I was passing the values to pipe-lined function directly.
IR Query..
SELECT * FROM TABLE(fn_pipeline(:P1_ITEM_NAME))Call pipe-lined function from IR query directly (instead of using view)
Try sending values to Pipe-lined function directly. In-case if the problem is with setting and getting values from the context?

Setting Value of apex_item.checkbox in interactive report

Forum
We need a "select all" and "unselect all" functionality in an interactive report ...
The IR Query currently goes something like this :
select
OBJ_LABEL",
"DATA_START_DATE",
"S_ROWSTATE",
"S_ROWVERSION",
APEX_ITEM.CHECKBOX(1,item_id, 'Checked') "Select"
from some_table;
We have the checkbox selected by default .... the question now is how to have an "unselect all" and "select all" function or heading in the Interactive Report that would unset or set the checkboxes for all rows in the report.
Any advice will be helpful ....
Thanks
Pierre

Answering our own question :-)
1) Add an unselect and select button and a hidden field
2) modify the query to use the value of the hidden field to determine whether the checkbox is set or not.
3) set the value of the hidden field as appropriate with for the select or unselect event when the button is selected.

Check all checkbox in an interactive report

Hi,
I would like to add a "check all" functionality in an interactive report. I've done that by adding a javascript function to the header, but when I click the column header to check all the page first executes the javascript that is used by the interactive report (sorting etc). Is there a way to disable this javascript for just the checkbox clolumn, so that my own javascript code is executed?
Or is there another way to add this functionality to the IR?
Thanks

That works great! Thanks jarola
The complete answer in case anyone needs it is to first include the checkbox column in your IRR query
APEX_ITEM.checkbox (1, ca.id) del
Then include this as the column heading
<input type="Checkbox" onclick="$f_CheckFirstColumn(this)">
Then include the code as identified by jarola in the page HTML Header
<script type="text/javascript">
addLoadEvent(RemoveChkOnclick)
function RemoveChkOnclick(){
$x('apexir_DEL').onclick='';
</script>

Interactive Report Download and Session State Protection

I have created an Interactive Report in an APEX application that I have enabled
session state protection for. The issue I am having is with the "Download"
functionality of the interactive report to a .csv file.
The URL created by selecting Download from the drop down (javascript:gReport.controls.download();)
is built or constructed without a checksum thus causing the error below.
Error
No checksum was provided to show processing for a page that
requires a checksum when one or more request, clear cache, or argument
values are passed as parameters.
The anchor tag containing the URL (/f?p=app_id:page:session_id:CSV:) is contained within
<div id="apexir_CONTROL_PANEL_DROP" class="drop_panel
clearfix" style="">
Running the following: Application Express 3.1.0.00.32 on Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
Is there a way to add a checksum to this? OR does anyone have any ideas on how to work around this?
Edited by: Bryce Tuohy on Feb 26, 2009 10:08 AM

WORKAROUND:
1.) Create hidden ITEM on page (I named it P23_PREPARED_CSV_DOWNLOAD_URL).
Enter the following for the ITEM
as the SOURCE_TYPE : PL/SQL Function Body
as the SOURCE: return apex_util.prepare_url('f?p=&APP_ID.:&APP_PAGE_ID.:&APP_SESSION.:CSV:')
2.) Create BUTTON that executes javascript to open POPUP window with this url.
a.) Create Button and enter
<a href="javascript:popupURL('&P23_PREPARED_CSV_DOWNLOAD_URL.')">Download and Save to CSV file</a>as the "Text Label/Alt"
Originally had custom code for javascript POPUP and this is not needed .... just use the APEX javascript function.

Interactive report: Can I exclude a particular column from single row view?

Hi -- I posted on this yesterday (Possible to exclude interactive report column from single row display?
a bit anxious for suggestions, I guess!
I've added a column with edit-link functionality to my interactive report query (that is, the link
is not attached to the database data... it's an additional column and shows an icon). It's also
in addition to the default single row view link. (We need both.)
Unfortunately, the Edit link column shows up in the single row view. I've pared it down as much
as I can: the label is empty, and the null value shows as "-". But an extra row with "-" is pretty
ugly. Is there a way to always, completely exclude this column from the single row view?
I know I could put the edit link on a data column, but:
1) I want the link to always be to the left of the data (and the user can re-order columns)
2) when the user doesn't have edit privileges, the link will need to be disabled or just not
be displayed, and I think that would be a problem if the link were on the data. (true?)
Thanks,
Carol

Please disregard this thread, and the one it refers back to. I see a flaw in the design of what I was attempting to do! Creating the link for Editing as a column means the user could inadvertently not display it, or move it, or... any number of problematic scenarios.
Thanks,
Carol

Interactive report – column heading in multiple rows

I am using interactive report. My question to the expert/guru’s is: - How do I change column heading into multiple row with text wrap.
For example:- My column heading is
Is Employee Trained ? -------> (single row display)
I want to make it display like
Is Employee
Trained ? ------> (Multi row display)

Hi,
What you could do is, disable the download csv function from IR (Interactive Report Attributes--> Search Bar-- Uncheck Download) and in the region header create a link and redirect it to another page which will have the csv report output.
e.g. <a href="#" onclick="javascript:redirect('f?p=&APP_ID.:3:&SESSION.::&DEBUG.:3::');"" >Download Report </a>
Here I am redirecting the link to Page 3. On Page 3 create a sql report with the same query and make report template to csv. Thanks,
Manish

How to apply an accent-insensitive search to an interactive report?

Hello all!
I'm trying to put an accent-insensitive search on an interactive report here. For example, if I'm on the page that has the interactive report and if I click the column header of the interactive report, I get to see a search bar that dynamically shows the results that match your input. Now, when I enter "jager", I want to see *"Jägermeister"* as a search result. The search must be accent-insensitive, so that I don't have to enter the ä every time.
My code is as follows:
SELECT name
FROM food_1
WHERE name LIKE 'Jagerme%'
AND NLSSORT(name) IS NOT NULL
ORDER BY NLSSORT(name, 'NLS_SORT=GENERIC_M_AI');As you can see, I first tried getting a result through the SQL Command. It should return the row that has "Jägermeister" as name. However, it doesn't. It tells me "No data found". So, how do I alter my NLSSORT to search accent-insensitive?
Some extra information, I edited the interactive report source to the following:
SELECT DISTINCT a.name, a.foodid
FROM food_1 a INNER JOIN foodunit_1 c
ON a.foodid = c.foodid
WHERE a.foodlanguageid = :P17_SET_LANGUAGE
AND NLSSORT(a.name) IS NOT NULL
ORDER BY NLSSORT(a.name, 'NLS_SORT=GENERIC_M_AI');I also tried doing ALTER SESSION before the SQL code, but it still gives me the same result: No data found.
I'm using APEX version 4.1.1.00.23.
Help and suggestions are more than welcome. ;)
Thanks in advance,
Magali

I found it out!
It's really ridiculous, actually.
Remember this code?
execute immediate ('ALTER session SET NLS_COMP=LINGUISTIC');
execute immediate ('ALTER session SET NLS_SORT=BINARY_AI');Well, this code is perfectly fine. Only, it doesn't execute. This is because it was misplaced...This process is not executed when you place it in the current authentication scheme, under the "Post-Authenticatoin Process" part.
You might wonder why this is, but I have the explanation to that.
You see, when you use an interactive report, the page processing isn't executed when you use the search function of that interactive report... Because it's an interactive report, I guess.
BUT.
An ALTER SESSION from the security attributes, that will execute.
So, the solution to my problem was, in this case:
Go to "Application" --> "Shared Objects" --> "Security Attributes" --> "Database Session" --> "Initialization PL/SQL code". In there, you need to put:
BEGIN
EXECUTE IMMEDIATE 'ALTER session SET NLS_COMP=LINGUISTIC';
EXECUTE IMMEDIATE 'ALTER session SET NLS_SORT=BINARY_AI';
END;By doing this, there's no longer any need to edit the source code of the report!
So, that's the solution. I can finally enter text without special characters in it, and get the corresponding data, with special characters... Ahh. :)
I hope this is helpful to others as well now. ;)

Interactive Report - Download as csv

Hi,
I am using apex 4.0.2.00.07 on IE8 with theme Traditional Blue. I have a problem with the inbuild download functionality of an interactive report. One field is of type varchar2 and I allow line breaks in the underlying edit screen.
I simply do not find a way to handle this formatting in the export to csv. The data is always completely shredded. An example:
Input form:
Name (text field):
Bob
Address (text area):
Street(<linebreak>)
City
IReport SQL: select NAME, ADDRESS from USERS
In the IR form it will show as
Name || Address
Bob || Street City
An export to csv will make this to
Name,"Address"
Bob,"Street
City"
I have tried all settings of the report attribute 'Display Type' for field Address, but it will always be the same in the IR and always the same in the export. How do I ensure that the whole content of a table field is displayed as one value in the csv, with no regards to potentially present field formatting, e.g. in my case:
Name,"Address"
Bob,"Street City"
And if we are already at it: I have seen that some plugins for an export to excel exist. Would that recognise the formatted text and place it in one cell or would I face the same issue here, i.e. the field value being split over several cells?
Thanks a lot,
Martin

Well, found some answers after some more trial and error.
1.) Country settings messed up my csv format. After changing the default column separator in the report attributes, things now look as expected.
2.) One can rather easily suppress the format signs by using the sql replace functionality, e.g.
SELECT REPLACE (my_column, CHR(10),' ') FROM my_table
And it is actually quite a difference if you use text area or rich text fields when it comes to the usage of the breaks.
Cheers,
Martin

Interactive report - conditional where clause

Hello,
i have an interactive report like
SELECT a.id, a.my_column
FROM my_table a
WHERE a.id = 12
Now, when the user select a assigned value, the where clause don't be execute, also like this (without where)
SELECT a.id, a.my_column
FROM my_table a
The User is not allowed to see this column, also i can not use the filter-function of the interactive report.
Any Idea how did i make?
thank's, Daniel

Hi Andy, this functionalitiy is clear.
I will manipulate the region source in fact of an interaction of a user.
Now, my select shows like:
SELECT a.* FROM v_test a
WHERE (:P40_ID = -1 OR a.id = :P40_ID)
:P40_ID is a select box with return-null-value of "-1".
This is not very fast. Therefore i search a method, when user select the null-value, then the select like:
SELECT a.* FROM v_test a;
and when user select another value then:
SELECT a.* FROM v_test a
WHERE a.id = :P40_ID;
All this without the "filter"-functionality of the IR!
Any idea?
Sorry for this misunderstood.
Daniel.
