Help me with this tricky sql....
i need a sql querry that displays ename,salary,max(salary) such that max(salary) should be in every column.
it should be like this...
Ename Salary max(Salary)
Smith 12000 18000
robert 8000 18000
frank 14000 18000
walter 18000 18000
stacy 5000 18000
thanks
sankar..
Hi, Sankar,
That's exactly what analytic functions do:
SELECT ename
, salary
, MAX (salary) OVER () AS max_salary
FROM table_x;"OVER (<analytic_clause>)" indicates that this is the analytic MAX function, not the aggregate MAX function.
You don't need an analytic clause in this case, but syntax still requires the parentheses in "OVER ()".

Help me with this tricky design!
I'm trying to do something that I tohught would be pretty easy but is turning out to be quite tricky...
UI is very hard to descirbe in words, so I made a diagram, please view it here:
http://members.verizon.net/~vze28272/ui_diagram.jpg
Basically, what I want is for when the user first loads this tab, he sees a standard horizontal split pane, with a JList on the narrower left side (labelled Section A) and a wider editor area on the right side (labelled section B).
But then the user can try to do a search, and when he does a third section will appear on the bottom, which will have a label, a button and a JTable displaying the results of the search.
I would like it to behave so that Section A & B are one JSplitPane nested inside a main JSplitPane split vertically, but somehow I want the bottom component only to appear when the user searches, and I'd like the user to be able to click a little button to hide that whole section again until next time he does a search...
I've been getting limited success, creating the nested SplitPane structure but I'm having trouble with hiding the bottom component when I dont want it... all I can do is make it small so its not entirely visible but then there's still that divider which they can grab and pull it up... I'd like that to be gone somehow..
So basically, how do I control visibility of this bottom component?
Any suggestions?I haven't tried it, but the following should work:
BasicSplitPaneUI ui = (BasicSplitPaneUI)splitPane.getUI();
ui.getDivider().setVisible(...); -
Please help me with this SQL query
I am practicing SQL queries and have come across one involving fetching data from 3 different tables.
The three tables are as below
<pre>
Country
location_id country
loc1 Spain
loc2 England
loc3 Spain
loc4 USA
loc5 Italy
loc6 USA
loc7 USA
</pre>
<pre>
User

u1 loc1
u2 loc1
u3 loc2

u5 loc1
u6 loc3

<pre>
Post
post_id user_id

I am trying to write an SQL query - for each country of users, display the average number of posts
I understand the logic behind this that we first need to group together all the locations and then the users belonging to one country and then find the average of their posts.
But, i'm having a difficulty in putting this in SQL form. Could someone please help me with this query.
Thanks.select
country.country,
count(*) Totalpostspercountry,
count(distinct post.user_id) Totaldistincuserspercountry,
count(*)/count(distinct post.user_id) Avgpostsperuserbycountry
from
country, muser, post
where country.location_id = muser.location_id
and muser.user_id = post.user_id
group by country.country
The output is like this for your sample data - hope this is what you were looking for :)
COUNTRY,TOTALPOSTSPERCOUNTRY,TOTALDISTINCUSERSPERCOUNTRY,AVGPOSTSPERUSERBYCOUNTRY
England,1,1,1,

The code is basically the same except that in the procedure the passing clause gets a differnt param, which is the passed in param from the procedure.
xmltable
xmlnamespaces
--- 'http://schemas.xmlsoap.org/soap/envelope/' as "saop",
'http://www.courts.state.mn.us/CourtXML/2.0.0' as "ic"
'for $ics in //ic:CaseNotification/ic:InterimConditionsNotification/ic:InterimConditionsOrder[@orderEventKey = $val/oeKey]/ic:InterimConditions
return
<ic:ICS>
<ic:ICSText>{$ics/ic:InterimConditionText}</ic:ICSText>
<ic:ICSAmount>{$ics/ic:InterimConditionAmount}</ic:ICSAmount>
</ic:ICS>'
passing p_XMLDoc, xmlelement("oeKey", v_OEKey) as "val"
columns
ICSText varchar2(100) path '/ic:ICS/ic:ICSText',
ICSAmount number path '/ic:ICS/ic:ICSAmount'
The strange thing is the procedure gets the ic:ICSText with the namespace value, which is http://www.courts.state.mn.us/CourtXML/2.0.0, so the finaly result is
the whole thing: <InterimConditionText xmlns="http://www.courts.state.mn.us/CourtXML/2.0.0">Anger management</InterimConditionText>.
I get the correct values when testing with the anonimous code!
What did I do wrong? Please help!
Thank you.
BenHi gurus,
OK, I did another test. I ran the same PL/SQL anonymous block that gets the correct element value in 10.2.0.3.0 and it gets the same wrong value: the element name plus the namespace value and the data itself. It gets the correct element value in 10.2.0.1.0 (my local database).
Could anyone help me with this?
Thanks!

Why do I get this error message??
Do I always have to provide the string in the format 'dd-mon-yyyy' or 'dd-mon-yy'?No, the 1st argument does not always have to be in a particular format. That's what the 2nd argument is for: it says what format the first argument is in.
It helps if you write the two arguments on separate lines, the 2nd rught below the 1st:
TO_DATE ( '12-oct'
, 'dd-mon'
)and
TO_DATE ( '12'
, 'dd'
)are both okay: the two arguments match.
The following, however, is wrong:
TO_DATE ( '12-oct' -- ERROR! This is 6 characters
, 'dd' -- This is only 2 characters
If so then why do I not get the error for something like:
select to_char(to_date(to_char(sysdate,'dd'),'dd'),'year') from dual;If you want to understand a complicated expression, break it down into parts, starting from the inside.
For example, start with
SELECT TO_CHAR (SYSDATE, 'dd')
FROM dual;Assuming today is October 22, 2010, this produces the string '22'.
So if the result of TO_CHAR (SYSDATE, 'dd') is '22', then
SELECT TO_DATE ( TO_CHAR (SYSDATE, 'DD')
, 'DD'
FROM dual;is equivalent to
SELECT TO_DATE ( '22'
, 'DD'
FROM dual;which returns tHE DATE October 22, 2010, 00:00:00. (When you don't specify the year or month, they default to the current year or month. when you don't specify the hurs, minutes or seconds, they default to 00.)
So, if d is a DATE, October 22, 2010, 00:00:00, then
SELECT TO_CHAR ( d
, 'year'
FROM dual;returns '2010'.
Don't take my word for it. Run these querries, and similar ones you think of, yourself. -
Can someone pls help me with this code
The method createScreen() creates the first screen wherein the user makes a selection if he wants all the data ,in a range or single data.The problem comes in when the user makes a selection of single.that then displays the singleScreen() method.Then the user has to input a key data like date or invoice no on the basis of which all the information for that set of data is selected.Now if the user inputs a wrong key that does not exist for the first time the program says invalid entry of data,after u click ok on the option pane it prompts him to enter the data again.But since then whenever the user inputs wrong data the program says wrong data but after displaying the singlescreen again does not wait for input from the user it again flashes the option pane with the invalid entry message.and this goes on doubling everytime the user inputs wrong data.the second wrong entry of data flashes the error message twice,the third wrong entry flashes the option pane message 4 times and so on.What actually happens is it does not wait at the singlescreen() for user to input data ,it straight goes into displaying the JOptionPane message for wrong data entry so we have to click the optiion pane twice,four times and so on.

}Hi,
I had a similar problem with a message dialog. Don't know if it is a bug, I was in a hurry and had no time to search the bug database... I found a solution by using keyPressed() and keyReleased() instead of keyTyped():
private boolean pressed = false;
public void keyPressed(KeyEvent e) {
pressed = true;
public void keyReleased(KeyEvent e) {
if (!pressed) {
e.consume();
return;
// Here you can test whatever key you want
//...I don't know if it will help you, but it worked for me.

"It is formatted incorrectly, or is not a format that iBooks can open". Can anyone help me with this message of a book that I purchased on iBooks, read, highlighted in the book and now I can't open it anymore. Please help!!!
Mine does the same thing occasionally, is your phone jailbroken? Sometimes it will work if you delete the book and reinstall it or put your phone into airplane mode then turn it back off.

I'm using iphoto9.1.3 but now it doesn't seem to work, whenever I try to open it, it just shows loading, but never loads. Can anybody help me with this ?
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

can anyone out there help me with this assignment ????? i`ll attach the file to this topic
In this assignment, you are to write a Java applet, using arrays, to simulate the functions of a drinks-vending machine.
The assignment requirements described below are broken down into 2 stages of development, described in this document
as 'Basic Requirements' and 'Additional Features'. You are advised to do your programming progressively in these
stages. An Activity Plan has also been specified for you to follow. Refer to the 'Grading Criteria' on page 5 to have
an idea of how the different components are graded.
1. 1. BACKGROUND
A company intends to build computerised drinks-vending machines to enlarge its business portfolio. You have been tasked to develop a
Java applet that simulates the operation of such a machine to determine if it will meet their needs.
2. 1. BASIC REQUIREMENTS
The machine should have a wide range of drinks available. A customer can choose a drink according to the following criteria:
a) a) Category of Drinks
� � Beverages
� � Soft Drinks
(For beverages, there is choice of whether sugar and/or creamer is required, for which there is an additional charge.)
b) b) Type of Beverages
� � Hot
� � Cold
Once a customer has specified the drink he wants, the amount payable is displayed. The unit prices to be displayed are as follows:
Drinks Price per Cup/Packet ($)
Beverage: Coffee 1.00
Tea 1.20
Milo 1.40
Horlicks 1.35
Chrysanthemum 1.00
Ginger 0.80
Soft Drinks: Apple 1.40
Orange 1.40
Pineapple 1.50
Carrot 2.00
Longan 1.20
Bandung 1.00
(For beverages, a request for sugar or creamer attracts an additional charge of $0.10 each. Creamer is not applicable for
chrysanthemum and ginger.)
The customer may then confirm his order by entering the amount payable (this symbolises his payment for the drink). Whenever the
payment input is not correct, an appropriate error message is displayed, whereupon the customer has to re-enter the amount again.
When the correct amount is paid, the required drink is dispensed.
For any drink that is out of stock, a message is shown, stating that it is not available. Each time a drink is dispensed, the stock for that
drink is updated (For beverages, the stock is stored in units of servings for each cup.) To simplify the testing, you may start the simulation
by setting the stock for each drink to 10 packets or cup-servings.
3. 2. ADDITIONAL FEATURES
In addition, the simulator can have the following features:
a) a) Smart Graphical User-Interface (GUI)
You may build upon the basic requirements by recommending alternative drinks of the same category, whenever a requested
drink is not available (as signified from the stock). In this case, only drinks which are available (i.e., in sufficient stock) are
displayed for the customer to choose. And if only soft drinks are available, the selections for creamer and sugar should be disabled.
b) b) Multiple Orders
A customer could order more than one drink. The system could allow him to specify as many drinks as he wants, prompting him
for an appropriate payment, and then dispensing the drinks accordingly, subject to availability. This may also entail the extension
of the graphical user-interface.
c) c) Sales Analysis
Periodically, the total revenue accumulated since the last collection is printed in descending order of sales for each drink sold,
together with a grand total. The cash is then cleared from the machine. This feature requires password-protection.
d) d) Replenishment of Stock
Periodically, the stock is checked to determine how much of each drink needs to be replenished. For this purpose, a list of the
drinks with the corresponding quantity on hand is printed in ascending order of stock level. Drinks with insufficient stock are
topped up to a level of 10 servings or packets. This feature also requires password-protection.
e) e) Any other relevant features
You are limited only by your creativity. You can add any other relevant features for this project. Please consult your tutor before
you proceed.
To qualify for the full marks for this section, you need to implement 2 features, at least one of which must be either (a) or (b) above.
4. 3. ACTIVITY PLAN
Suggestions for Getting Started
There are many ways that you could complete this assignment. The most important part is to think about the entire project first so that
it is easy to integrate the various pieces. You should also consider what type of graphics you want to incorporate.
a) a) Analysis
1. Understand the program specification and the requirements before attempting the project.
b) b) Program Design
2. Work out the GUI components (e.g., TextFields, CheckBoxes, ChoiceBoxes, Buttons, etc.) needed to get the user input.
3. 3. Work out the main logic of the program using modular programming techniques; i.e. use methods appropriately. E.g., tasks that perform
4. 4. a well-defined function or those that are repeated should be coded as methods. For example, you can write the methods, displayBill(),
5. 5. makePayment(), computeTotal(), dispenseDrink(), etc. You need to think carefully about the return type and the parameters of each
6. 6. method.
7. 7. You are required to use arrays appropriately for this assignment. Marks will be deducted for inefficient use or non-usage of arrays.
c) Implementation & Testing
8. 8. Write the method definition of each method ONE at a time.
9. 9. Test your program logic to make sure that it works. In the interim, you can use �g.drawString(�);� or �System.out.println(�);� to print
10. 10. out intermediate results so that you can see whether your program is working correctly. You may not want to bother about error-checking
11. 11. at this point. You should test each method as soon as it is written, as it is much easier to debug your program in this way.
5. 4. DELIVERABLES
By Monday, 25th February before 5:00 p.m., hand in the following to the School of ICT Administrative Office at Block 31, level 8:
� � A copy of the printout of your .java file.
� � A diskette labelled with your name, group, student ID. The diskette should contain ALL the necessary files (.java, .html, and .class)
to run your applet.
� � The above in an envelope topped with the Assignment Completion Report (see pages 6, 7 & 8). Page 6 is for you to paste on top
of your envelope whilst pages 7 and 8 are for you to document your Test Plan, and write your comments (including any
special instructions to run your program) - to be inserted into the envelope.
In your .java program, you are to include a blocked comment at the top stating:
q q Your name, group, student ID.
q q Assumptions (if any) or any deviations from the specified requirements.
q q Any features that you would like to highlight.
6. 5. WALK-THROUGH OF PROGRAM
Monday 25th February at 9:30 a.m. SHARP
In the walk-through, you will be asked to give short, written answers to some questions about your program. These questions will assess
your basic understanding of the code that you are handing in. If you fail to display adequate understanding of your own program, you can
be down-graded by up to two letter grades from what you would have normally received. It is also possible that you will be called to
perform a demonstration cum explanation of your work if it is suspected that you have copied someone else�s work. Lesson: do your own
work and you will have no problem!
7. 6. GRADING CRITERIA FOR PROGRAMMING
Correct and robust implementation of basic features 55 %
Additional features 20 %
Programming style:� � Program design� � Appropriate use of arrays� � Appropriate use of variables, methods, and parameters� � Proper usage of control structures (e.g. if/else, loops) 15 %
Good programming practice:� � Meaningful variable names � � Proper indentations� � Useful and neat comments 5 %
Adequate (black-box) testing:� � Suitably-designed test plan 5 %
