Help on function show_document

Hi to all,
in a form (10g) I have a button. When the button is pressed I want to call the function Web.show_document in order to display, for example, the html file test.html in the browser.
1) in witch folder of Oracle home must be reside the html files?
2) If I run my app in the browse with a command like this:
http://SERVER_IP:7778/forms90/f90servlet?config=myappconf
must I configure some file of oracle (for example forms90.conf) and if yes wich is the correct string that I must pass to Function ?
I hope in Your help in order to resolve this problem.
Thank You and Best Regards
Gaetano

You would need to setup a virtual directory in Apache. By default Forms comes with a couple of them which you can see in the forms.conf file.
Some examples from my 10.1.2.0.2 developer suite install:
AliasMatch ^/forms/java/(..*) "C:\oracle\product\10.1.2\ds_2/forms/java/$1"
AliasMatch ^/forms/jinitiator/(..*) "C:\oracle\product\10.1.2\ds_2/jinit/$1"
AliasMatch ^/forms/html/(..*) "C:\oracle\product\10.1.2\ds_2/tools/web/html/$1"
AliasMatch ^/forms/webutil/(..*) "C:\oracle\product\10.1.2\ds_2/forms/webutil/$1"
From this you can see that http://server:port/forms/java/file.html will point to physical file C:\oracle\product\10.1.2\ds_2/forms/java/file.html
You could just dump your HTML files in any of the directories that are already mapped by an AliasMatch. But if you want to keep it nice and clean you probably want to create a new physical directory and include a new AliasMatch directive in the forms.conf file or in the main Apache config file.

Custom Search Help for Functional Area of Cost Centre(KS01/KS02)

Hi,
I need to implement a custom search help and custom enhancement for the field Functional Area in Basic Data tab of Cost Centre Create/Change(KS01/KS02) transactions. Details of the requirement are as below:
1. There will be a custom relation for the Cost Centre category and Functional Area which was maintained thru a SAP standard table TKA05 and a custom table.
2.When the relation to Cost Centre category and Functional Area is a one to one it exist in the TKA05 and if its one to many it will be maintained in the custom table.
3. The requirement is when the Cost Center to Functional area is maintained in table TKA05(One to One) in this case the corresponding Functional Area needs to be populated automatically after entering the cost centre and pressing a enter key by user.
4.When the Cost Centre Category and Functional area does not exist in table TKA05 and existing in custom table(One to Many) in this case the F4 should be enabled for user selection with the list of Functional area values corresponding to the cost centre category entered that are maintained in the custom table.
As per the functionality provided by SAP the input help(F4) of the field Functional area in Cost Center does not have any relation with Cost Centre Category. The existing F4 is from the Value Table(TFKB) attached to the domain of FKBER.
Please provide your valuable inputs to implement the above requirement. Your input will be rewareded.
Thanks in advance,
Regards,
Prasad.

kalyani,
i can see your requirement in below way..
as it just reads: you need to assign the standard cost center help to a z cost center field in component /SAPSRM/WDC_UI_DO_ACC.. which actually is fetched though the component /SAPSRM/WDC_UI_BACKEND_SH
so, if you see the component controller of SAPSRM/WDC_UI_DO_ACC you will see the component
USAGE_SH_F4 /SAPSRM/WDC_UI_BACKEND_SH
USAGE_SH_F4 /SAPSRM/WDC_UI_BACKEND_SH INTERFACECONTROLLER
so you can replicate the same functionality for your z field.
but can you clarify one thing.. why are you going for this z field in place of standard field ?

HELP MENU FUNCTION-URGENT HELP PLZ.

Hello there. I've been trying to design a GUI providing the users with help function as well. I create the html file, map file(in .jhm format) and HelpSet (in .hs format) and run the help menu via hsviewer. The first problem is that when the hsviewer runs the application a blank help window appears on the screen. The second one is that when I try to make a link between the help menu and the GUI I have written by using the sample code given in javahelp's pdf file I see a few error messages on NETBEANS' screen. Could anyone help me solve the problems I have faced so far? In addition, aint there any other method, like a template help menu, that I could use to compose my own one?

* stop multi-posting
* stop SHOUTING
* whenever you see error messages and have some problem, those two are probably related
* whenever you ask for help and have error messages post the error messages!

Help menu function plz help:)))

[8i] Help with function with parameters (for workday calculation)

Let me start by saying, I've never written a function before, and I don't have access to create a function in my database (i.e. I can't test this function). I'm trying to come up with a function that I can ask my IT department to add for me. I'm hoping someone can take a look at what I've written and tell me if it should work or not, and if this is the right way to go about solving my problem.
I am trying to create a function to do a very simple workday calculation (adding/subtracting a particular number of workdays from a calendar date).
The database I'm working with has a table with the workday calendar in it. Here is a sample table and sample data, representative of what's in my workday calendar table:
CREATE TABLE caln
(     clndr_dt     DATE,
     shop_days     NUMBER(5)
     CONSTRAINT caln_pk PRIMARY KEY (clndr_dt)
INSERT INTO     caln
VALUES (To_Date('01/01/1980','mm/dd/yyyy'),0);
INSERT INTO     caln
VALUES (To_Date('01/02/1980','mm/dd/yyyy'),1);
INSERT INTO     caln
VALUES (To_Date('01/03/1980','mm/dd/yyyy'),2);
INSERT INTO     caln
VALUES (To_Date('01/04/1980','mm/dd/yyyy'),3);
INSERT INTO     caln
VALUES (To_Date('01/05/1980','mm/dd/yyyy'),3);
INSERT INTO     caln
VALUES (To_Date('01/06/1980','mm/dd/yyyy'),3);
INSERT INTO     caln
VALUES (To_Date('01/07/1980','mm/dd/yyyy'),4);
INSERT INTO     caln
VALUES (To_Date('01/08/1980','mm/dd/yyyy'),5);
INSERT INTO     caln
VALUES (To_Date('01/09/1980','mm/dd/yyyy'),6);
INSERT INTO     caln
VALUES (To_Date('01/10/1980','mm/dd/yyyy'),7);
INSERT INTO     caln
VALUES (To_Date('01/11/1980','mm/dd/yyyy'),8);
INSERT INTO     caln
VALUES (To_Date('01/12/1980','mm/dd/yyyy'),8);
INSERT INTO     caln
VALUES (To_Date('01/13/1980','mm/dd/yyyy'),8);
INSERT INTO     caln
VALUES (To_Date('01/14/1980','mm/dd/yyyy'),9);The actual table includes from 1/1/1980 though 12/31/2015.
I've written (and validated) this parameter query which does my workday (mday) calculation:
SELECT     cal.clndr_dt
FROM     CALN cal
     SELECT     cal.shop_days+:mdays     AS new_shop_days
     FROM     CALN cal
     WHERE     cal.clndr_dt     =:start_date
     ) a
WHERE     cal.shop_days     = a.new_shop_days
AND     ROWNUM          =1
ORDER BY     cal.clndr_dt;Based on this query, I've created the following function (and I have no clue if it works or if the syntax is right, etc.):
CREATE OR REPLACE FUNCTION add_mdays
     (start_date     IN DATE,
     mdays          IN NUMBER(5))
RETURN     DATE
IS
     new_date DATE;
BEGIN
     SELECT     cal.clndr_dt
     FROM     CALN cal
          SELECT     cal.shop_days+mdays     AS new_shop_days
          FROM     CALN cal
          WHERE     cal.clndr_dt     =start_date
          ) a
     WHERE     cal.shop_days     = a.new_shop_days
     AND     ROWNUM          =1
     ORDER BY     cal.clndr_dt;
     RETURN     new_date;
END add_mdays; //edit 9:31 AM - noticed I left off this bitI'm also not sure how to have the function handle results that would return a date outside of the date range that is in the table (Before 1/1/1980 or after 12/31/2015--or, another way to look at it is, before the MIN value of caln.clndr_dt or after the MAX value of caln.clndr_dt).
My goal is to be able to use the function in a situation like the following:
First, here's a sample table and data:
CREATE TABLE orders
(     ord_no          NUMBER(5),
     plan_start_dt     DATE,
     CONSTRAINT orders_pk PRIMARY KEY (ord_no)
INSERT INTO orders
VALUES (1,To_Date('01/08/1980','mm/dd/yyyy'));
INSERT INTO orders
VALUES (2,To_Date('01/09/1980','mm/dd/yyyy'));
INSERT INTO orders
VALUES (3,To_Date('01/10/1980','mm/dd/yyyy'));And here is how I would like to use my function:
SELECT     orders.ord_no
,     orders.plan_start_dt
,     add_mdays(orders.plan_start_dt, -3) AS prep_date
FROM     ordersThus, the function would allow me to return, for every order in my orders table, the date that is 3 workdays (mdays) prior to the plan start date of each order.
Am I going about this the right way? Do I need to create a function to do this, or is there a way for me to incorporate my query (that does my mday calculation) into the sample query above (eliminating the need to create a function)?
Thanks much in advance!

Fixed a couple typos in the last insert statements
Edited by: user11033437 on Feb 2, 2010 9:31 AM (fixed some syntax in the function)

Hi,
Ah, mentioning Oracle 8 and not being able to test your own code makes me nostalgic for the good old days, when you typed your cards, and brought them to a window at the computer center, and waited an hour for the job to run, and then saw the printout to find that you had made a typo.
If you're going to write functions, you really need to test them yourself. Like all code, functions whould be written in baby steps: write a line or two (or sometimes just part of what will later become one line), test, make sure it's running correctly, and repeat.
Ideally, your employer should create a developement schema in a development database for you to use.
You can legally download your own instance of Oracle Express Edition for free; just be careful not to use features that aren't available in the database where the code will be deployed.
You don't need a function to get the results you want:
SELECT       o.ord_no
,       o.plan_start_dt
,       MIN (e.clndr_dt)     AS prep_date
FROM       orders     o
,       caln          l
,       caln          e
WHERE       l.clndr_dt     = o.plan_start_dt
AND       e.shop_days     = l.shop_days - 3
GROUP BY o.ord_no
,            o.plan_start_dt
;This would be more efficient (and a little simpler) if you added a column (let's call it work_day) that identified if each row represented a work_day or not.
For each value of shop_days, exactly 1 row will be marked as a work day.
Then the query might be something like:
SELECT       o.ord_no
,       o.plan_start_dt
,       e.clndr_dt          AS prep_date
FROM       orders     o
,       caln          l
,       caln          e
WHERE       l.clndr_dt     = o.plan_start_dt
AND       e.shop_days     = l.shop_days - 3
AND       e.work_day     = 1
;You could use the analytic LAG function to populate the work_day column.
A function would certainly be handy, though perhaps slower.
The function you posted has a few mistakes:
(a) An argument can't be declared as NUMBER (5); just NUMBER.
(b) When you SELECT in PL/SQL, like you're doing, you have to SELECT INTO some variable to hold the results.
(c) ROWNUM is arbitrary (which makes it useless in this problem) unless you are drawing from an ordered sub-query. I don't think you can use ORDER BY in sub-queries in Oracle 8. Use the analytic ROW_NUMBER function instead.
(d) The function must end with an END statement.
Given your current caln table, here's how I would write the function:
CREATE OR REPLACE FUNCTION add_mdays
     ( start_date     IN           DATE          DEFAULT     SYSDATE,
       mdays          IN           NUMBER          DEFAULT     1
RETURN     DATE
DETERMINISTIC
IS
     --     add_mdays returns the DATE that is mdays working days
     --     after start_date. (If mdays < 0, the DATE returned
     --     will be before start_date).
     --     Work days do not include Saturdays, Sundays or holidays
     --     as indicated in the caln table.
     new_date     DATE;          -- to be returned
BEGIN
     SELECT     MIN (t.clndr_dt)
     INTO     new_date
     FROM     caln     f     -- f stands for "from"
     ,     caln     t     -- t stands for "to"
     WHERE     f.clndr_dt     = TRUNC (start_date)
     AND     t.shop_days     = f.shop_days + TRUNC (mdays)
     RETURN     new_date;
END     add_mdays;
SHOW ERRORSProduction code whould be robust (that includes "idiot-proofing").
Try to foresee what errors people might make in calling your function, and correct for them when possible.
For example, if it only makes sense for start_date to be midnight, or mdays to be an integer, then use TRUNC in the function in case soembody passes a bad value.
Allow for default arguments.
Comment your function. Put all comments within the function (that is, after CREATE and before the final END) so that they will be kept in the data dictionary.
If, given the same arguments, the function always returns the same value, mark it as DETERMINISTIC, for efficiency. This means the system may remember values passed back rather than call the function every time it is told to.
I wish I could mark questions as "Correct" or "Helpful"; you'd get 10 points for sure.
You posted CREATE TABLE and INSERT statements (without even being begged).
You gave a clear description of the problem, including desired results.
The code is nicely formatted and easy to read.
All around, one of the most thoughtful, well-written questions I've seen.
Well done! Keep up the good work!

Help with functions please

hello
im new to actionscript and im still trying to work out the basics
i have functions like this
private function sinus( phase: Number ): Number
return Math.sin( phase * Math.PI );
private function sawtooth( phase: Number ): Number
return ( phase - int( phase ) ) - 1;
inside another function it uses sinus like this
amplitude = sinus(_phase)
say i have 2 radio buttons called saw_btn and sin_btn
how could i chose between sinus and sawtooth at runtime?
somebody mentioned i could use a Function object reference
what is this?
how would i write that?
thanks in advance for your help

what kg means here is that you can 'target' a method by name using a string and the access operator. if you are doing so from within the Class Note, then you can use: amplitude = this[theStringGoesHere](_phase);
the string will be 'set' by your Radio button instances, then by changing the string (eg. clicking a radio button) the next time the method is called, it will fire the one that relates to the string 'by name' (the exact name of the method, case sensitive) - the keyword 'this' is referring to the scope of the Class you are in, (eg. Note)
you could do this directly like so: amplitude = this['sinus'](_phase);
but the purpose of using a variable within the accessor, is to allow you the ability to change it at will and effect the next operation of the method, and/or the value of 'amplitude'
- hope that helps shed some light on things

Why is Flash Help/Search function so worthless?

Is it just me or is the Flash help function the worst help
function ever?
In other software you get the results you were looking for in
seconds
in Flash everytime you do a search you get like a hundred
different
search results and usually none cover the topic you were
looking for.
Its often easier to search on google than use the internal
help function
Why is it so hard to only display relevant results?
Could anyone teach me how to use the search function cause I
dont want
to read 1000 pages just to find out the difference between
align and distribute
options etc.
Thx /AquaStealth

Help String Function To Upper

Hi guys,
I want to edit a string by using a function like UpperCase or LowerCase. Is there any function in ABAP which has the same functionality?
next problem is:
Can i use this function in an SQL query?
Like:        Select SINGLE IDSEGMENT
             FROM Table
             INTO IDSEG
             WHERE Upcase(string1) = Upcase(string2).
Is this possible?
Problem is that in the DB the string1 is spelled different (capital letters) than string2

Hi,
Try this out
*Code to demonstrate TRANSLATE to UPPER/LOWER CASE command
DATA: ld_char(20) type c.
ld_char = 'Hello World'.
TRANSLATE ld_char TO UPPER CASE. "Result: ld_char = 'HELLO WORLD'
TRANSLATE ld_char TO LOWER CASE. "Result: ld_char = 'hello world'
See this link
