Help with some functions
Hello All,
I encountered this question:
Evaluate the following SQL statements:
SELECT INTERVAL '300' MONTH,
INTERVAL '54-2' YEAR TO MONTH,
INTERVAL '11:12:10.1234567' HOUR TO SECOND
FROM DUAL;
Can any body help me with this, i do not even understand what they want.
Thanks
Harry

Hello All,
I encountered this question:Where?
Is this part of a homework assignment? Give a little context. It sounds like it's part of a unit that covers INTERVAL datatypes.
Evaluate the following SQL statements:
SELECT INTERVAL '300' MONTH,
INTERVAL '54-2' YEAR TO MONTH,
INTERVAL '11:12:10.1234567' HOUR TO SECOND
FROM DUAL;
Can any body help me with this, i do not even understand what they want.Neither do I; that's one reason why knowing a little more about where you encountered this question might help.
I think the question means "Execute this statement, then describe and explain the results."
What do you see when you run the statement you posted?
Do all three columns seem to be the same sort of datatype? If one differs from the other two, how does it differ? What's different about the corresponding item in the SELECT clause of your SQL statement?
What do you know about INTERVAL data types? "Nothing" is a perfectly legitimate answer; if that is your answer, then look up INTERVAL datatypes (INTERVAL DAY TO SECOND and INTERVAL YEAR TO MONTH) in your textbook and in the Oracle SQL language manual:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/sql_elements001.htm#sthref134
If you'd like help, do as much as you can, then post a more specific question.

Please help with some function module
Dear All,
We are trying to get data for excise duties based eg. BED, ECS, SECESS in the PO printout. Can anyone please suggest any function module through which excise duty can be calculated. For condition types other than ED we are using function module CALCULATE_TAX_ITEM. Please help.
Thanks and regards,

select (date2-date1)/24 from dual;date2-date1 is amount of days. Divide it by 24 and what? if you multiply it on 24 you will have a chance to know how many hours between these two dates. :-)Don't forget that a DATE type also includes a time component.I suppose it doesn't matter if you did a difference between two dates. The result is always number of days. -
Hello, I am new to java and I need a bit of help with some code that I'm writing. here is the code:
import javax.swing.*;
public class Test{
public static void main(String[] args){
JOptionPane.showMessageDialog(null,"We will now build a block with *'s","Block",1);
String input=JOptionPane.showInputDialog(null,"Type a number: ","Number",3);
int number=Integer.parseInt(input);
int count=0; int count2=0;
for(count2=0; count2<number; count2++){
for(count=0; count<number; count++){
System.out.print("* ");
System.exit(0);
}Now, all I need is to build a block of *'s with the number that the user inputs. With the code that I wrote I get the correct number of *'s but not in the form of a block. They just print out in a straight line. I know this is a very simple task but could someone please help me out? What do I need to modify in my code so that the *'s print out arranged as a block like so:
**********Your code only uses the print method which prints without a carriage return/line feed. So you need to add a line of code to print a carriage return/line feed. Where? well that is your task to work out.

Strange syntax error message with some functions!
Hello!
I have a strange trouble with some functions in Numbers.
For example when I try an IF function directly copied and pasted from Numbers documentation I get an error from Numbers that “the formula contains a syntax error.
*The function looks like this:*
*=IF(E6>=0, “Nonnegative”,”Negative”)*
*The value in cell E6 is 25.*
Anyone have a clue about why?Hello
If you enter my iDisk
<http://idisk.mac.com/koenigyvan-Public?view=web>
You will be able to download:
suriWork:for_Numbers:pour_modifierNumbers.zip
Which gives the ability to change the Numbers behavior (same thing for Pages and Keynote).
Applying it you will get an "Insert functions" tool matching your local settings.
It will insert functions using the semi-colon as parameters delimiter.

Help with some movie clips and an function...

Please help me out :-<
The code :sItem2 is a string and strings don't have _x etc properties.
"movie1" should be a movieclip, not a string when passed to
fSwitch() and fSwtich parameter typing should be changed. or
convert "movie1" into a movieclip in fSwitch()
to remedy the issue with sItem2, use a reference to your
movieclip created by attachMovie().

Help with some date functions.
I need to write code that allows a person to, at the beginning of a year, cancel all records that pertained to the prior year.
E.g., on 1/5/11, all records for the 2010 year would need to be cancelled by inserting the cancellation_date as the last date of that prior year.
So I thought the best way to do this would be with this function:
CREATE OR REPLACE FUNCTION TEST2
RETURN DATE
AS
v_prior_year CHAR(4);
v_last_second_string VARCHAR2(20);
v_last_second_date DATE;
BEGIN
-- Extract the year from the SYSDATE, convert it to a number, subtract 1, convert that year back to a string.
v_prior_year := TO_CHAR(TO_NUMBER(TO_CHAR (SYSDATE, 'YYYY'))-1);
-- Construct a string consisting of the last second of that year.
v_last_second_string := '31-DEC-' || v_prior_year || ' 235959';
-- Convert that string back to a date.
v_last_second_date := TO_DATE(v_last_second_string, 'DD-MON-YYYY HH24MISS');
RETURN v_last_second_date;
END Test2;
I was just wondering if there is a shorter way to do this?

You're saying that truncating the YYYY of the sysdate brings you to midnight of the first day of that year?Yes ... the absolute beginning of the year.

[8i] Need help with some workday calculations
At the beginning of the month, I got help with a workday calculation in: [8i] Help with function with parameters (for workday calculation)
Now, as it turns out, I was able to locate a function in the database that does what I want, however, it is much slower to use the function than to join two copies of the CALN table (Please see referenced thread for details. I can copy them to this thread if necessary.) I need to verify that the pre-existing function has 'DETERMINISTIC' in it, as I would guess that if it doesn't, it would be much slower than it could be.
But now, I've come across a situation where I have to do multiple workday calculations in the same query--enough that I have to join 6 copies of my CALN table. I can't imagine that is at all efficient. I believe it was Frank K. who said (in the original thread) that if the function was slow, I should consider alternatives. Can anyone help me identify some of those alternatives? I'm definitely at that point now. (This query is one I'm using as the base for a report in Oracle BI, and let's just say it doesn't like my query, even though my syntax appears to be correct, and I would guess that joining 6 copies of one table is at least partly to blame for this).
Note: I'm working with Oracle 8iOK, I finally have some sample data... I tried to make it thorough. I've included data in the CALN table YTD + tomorrow, so that any workday calculations using SYSDATE will work.

Hi all,
I need some help with ASO mdx function.
Avg({Leaves([Employees].Currentmember)}, [Calculated_Field]). This will give me the average for Calculated_Field for all levels of Employees. But i want to add more dimensions like Region and year.
Please advice how can I achieve this.
Thanks
Andyyou have to use cross join in order to add more dimension members to the formula.This will give you some idea

Help with Sort function in Terminal
Hello all... this is my first post on here as I'm having some trouble with some Termianl commands. I'm trying to learn Terminal at the moment as it is but I would appreciate some help with this one....
I'm trying to sort a rather large txt file into alphabetical order and also delete any duplicates. I've been using the following command in Terminal:
sort -u words.txt > words1.txt
but after a while I get the following error
sort: string comparison failed: Illegal byte sequence
sort: Set LC_ALL='C' to work around the problem.
sort: The strings compared were `ariadnetr\345dens\r' and `ariadnetr\345ds\r'.
What should my initial command be? What is Set LC_ALL='C'?
Hope you guys can help?Various languages distinct sorting - collation - sequences.
The characters can and variously do sort differently, depending on what language is involved.
Languages here can include the written languages of humans, and a few settings associated with programming languages. This is all part of what is known as internationalization and localization, and there are are various documents around on that topic.
The LC_ALL environment variable sets all of the locale-related settings en-mass, including the collation sequence that is established via LC_COLLATE et al, and the sort tool is suggesting selecting the C language collation.
Here, the tool is suggesting the following syntax:
LC_ALL=C sort -u words.txt > words1.txt
This can also be done by exporting the LC_ALL, but it's probably better to just do this locally before invoking the tool.
Also look at the lines of text in question within the files, and confirm the character encoding of the file.
Files can have different character encodings, and there's no reliable means to guess the encoding. For some related information, see the file command:
file words.txt
...and start reading some of the materials on internationalization and localization that are posted around the 'net. Here's Apple's top-level overview.
In this case, it looks like there's an "odd" character and probably an å character on that line and apparently the Svenska ariadnetrådens.
Switching collation can help here, or - if the character is not necessary - removing it via tr or replacing it via sed can be equally effective solutions.
Given it appears to be Svenska, it might work better to switch to Svenska collation thanto the suggested C collation.
I think that's going to be sv_SE, which would make the command:
LC_ALL=sv_SE sort -u words.txt > words1.txt
This is all generic bash shell scripting stuff, and not specific to OS X. If you haven't already seen them, the folks over at tldp have various guides including a bash guide for beginners, and an advanced bash scripting guide - both can be worth skimming. They're not exactly the same as bash on OS X and some specific commands and switches can differ, and as bash versions can differ, but bash is quite similar across all the platforms. -
Help with some java work ... :(
Hi, I was wondering can anyone here give me some help or show me the way with this programming assignment. This is my first week of programming in Java and is really struggling ...
I already have some very useful help from some people on here but still have no luck.
Below is what my assignment is about and what I've done so far, sorry if it's very basic but I'm trying my hardest.
You are required to write a program in Java that can store the details of three books. Their details are
Author
Shelf location
Availability
The program should give each book a unique shelf location starting from 0001. The details should be entered from the keyboard. The program should, on request, be able to print the details of each book to the screen. The program should terminate on request. The program should first ask for a preset password to be given before continuing executing any operation described above
public class Library {
public static void main(String[] args) {
String[][] books =
{ "Shelf Location", "Author ", "Book Name ", "Availability" },
{ "0001 ", "A. Smith ", "Hello World ", "1 " },
{ "0002 ", "C. Jones ", "Goodbye World ", "0 " },
{ "0003 ", "D. Wan ", "Whatever ", "5 " }
for (int i = 0; i < books.length; i++) {
System.out.print(books[0] + " ");
for (int j = 1; j < books[i].length; j++) {
System.out.print(books[i][j] + " ");
System.out.println();
import java.io.*;
public class Login2
private static BufferedReader in;
private static BufferedReader keyboard;
public static void main(String[] args) throws IOException
keyboard = new BufferedReader(
new InputStreamReader(System.in));
String input;
boolean done = false;
while (!done)
System.out.print("Enter Password in UPPERCASE (QUIT to exit)");
input = keyboard.readLine();
if ((input.equals("LOGIN")) || (input.equalsIgnoreCase("QUIT")))
done =
true;
return.Library();
I was told to use cases, instances, etc ... nothing complicated is needed but it is still to much for me. I saw some examples of people's work and they only have approx 1.5 pages of code.
Thanx very much for people who reads this thread and offers me help.Here's something to play around with (minimal error handling)
import java.io.*;
class Library

System.out.print("\nLibrary Options - \n0 - quit\n1 - Enter book details"+
"\n2 - List book details\n\nPlease enter selection number: ");
int selection = Integer.parseInt(br.readLine());
if(selection == 0) goodBye();
else
checkPassword();
if(selection == 1) newBook();
else listBook();
private void newBook() throws IOException
String another="";
do
if(bookTotal == books.length)
System.out.println("Unable to add more books");
return;
books[bookTotal] = new String[4];

"\nEnter availability details: ");
books[bookTotal][3] = br.readLine();
bookTotal++;
System.out.print("\nEnter another book? (y/n): ");
another = br.readLine();
}while(another.toLowerCase().equals("y"));
options();

String another="";
String titles = "\n";

do
System.out.print(titles+ "Please enter selection number: ");

Hi Expert,
I need help witht the functionmodule i just need to write a FM which has to read all the layouts Input values and multiply a percentage to create a new amounts. so is that i need to have both functionmdule and initializer and it will great if you can explain with some ABAP programs. so that i can follow up.See this FM : UPF_QUOTA_PLANNING
You can code accordingly; init is optional; you dont init FM.

Hello, i'm trying to do add some transitions to my video. I want to do a intro like this: http://www.youtube.com/watch?v=aBPV0f6c56s
I have already written the swords, the texts and the central anime minecraft guy with Anime Studio, but i need to do this 3 things:
1. Am expanding cirle opening
2. A light/flash as transition between the first animation and the next logo
(I have another question, but more difficult: I want to do a sun rays effect from an angle)
All of these effects-transitions are in the youtube video that i linked.
Can someone help me with one of these questions?
I have Adobe After Effects and Premiere Pro.
Thank you for the attention.The circle wipe is just that, a transition. Look in Effects>Transition. I'll give you a clue, a circle has a radius... It's there along with some more interesting effects.
You can also do a circle transition with a simple animated mask, use a scaled round layer as a track matte or about a hundred other combinations.
The light burst effect can be done with a simple masked white solid blend mode set to add and opacity keyframes or by searching your effects and pre-sets for light b. You'll find it. Just add it to a solid between your layers, set the blend mode to add and use an animated mask and opacity to bring in the effect. (the yellow thing in the middle is the animated mask that makes CC light burst interesting.
Same thing can be used for your sun rays. It's just a matter of layering and the shape of your mask.
Here again, there are dozens of ways to achieve this effect.
If you're completely lost then start here. This is basic enough AE that you shouldn't really need a step by step tutorial to pull it off.
Or as dave suggested, get Anime Studio.
