Selecting top x rows for each of the groupby clause

Hi Gurus (again).
I have this query to select the top 24 rows:
select * from
+(+
select proid, to_char((next_day(trunc(request_date, 'iw'), 'mon')-7), 'YYYY') as YEAR, to_char(request_date, 'IW') as WEEK,
next_day(trunc(request_date, 'iw'), 'mon')-7 as weekdate,
trunc(avg(case when report_date > request_date then ((report_date - request_date) * 24) end),1) as avg_ERT_hr, '24' as ERT_goal,
trunc(avg(case when response_date > request_date then ((response_date - request_date) * 24) end),1) as avg_IRT_hr, '48' as IRT_goal,
trunc(avg(case when deliver_date > request_date then ((deliver_date - request_date)) end),1) as avg_IDT_day, '0' as IDT_goal,
trunc(avg(case when complete_date > request_date then ((complete_date - request_date)) end),1) as avg_ORT_day, '0' as ORT_goal
from biw_hda_event
where request_date is not null
group by proid, to_char((next_day(trunc(request_date, 'iw'), 'mon')-7), 'YYYY'), to_char(request_date, 'IW'), next_day(trunc(request_date, 'IW'), 'MON')-7
order by 1 desc, 2 desc
+) where rownum <=24+
The problem here is that I have a group by "proid" clause in addition to the dates. My purpose is to be able to select the top 24 rows for each of the "proid" that is already grouped by the date. Essentially, the top 24 is the last 24 weeks pertaining to that "proid". How can I do this effectively without creating heaps of UNION clause for each of the "proid"?
thanks in advance

Top 10 rows in a pivot table

Hello,
I have an requirement to retrieve top 10 rows from the output pivot table.
Data on pivot table is structured as follows
Rows Measures
"Name" "Grade" "Value North" "Value South" "Total Value"
ABC A 100 200 300
BCD B 200 300 500
In the output there are 50 such rows and I want to display the top 10 rows with max Total Value.
Is it possible to achieve in OBIEE?
Any help is appreciated.
Regards,
Mukesh

Thanks or your reply.
I think I have not explained the issue correctly.
Source data is like this
"Name" "Grade" "Region" "Value "
ABC A North 100
ABC A South 200
BCD B North 200
BCD B South 300
So there is no Total value column in the report criteria.
I am using Pivot table to pivot the rows for ABC and BCD into a single row and then using the measure agreegation to generate Total Value column in pivot table only. The filter "is Top 10" available in report criteria so can not be applied on the pivot table.
Will try to implement the solution provided by BTK.

Top N rows based on aggregate function

Hi,
I need to get a report in the following format
F_A F_B F_C Count_comb
100 200 300 5
100 201 300 5
100 202 301 4
100 203 111 3
Here, the Count_comb column gives the count of records which have the same (F_A + F_B + F_C) combination. The requirement is to show the Top-N combinations where the tied rows would have the same rank --that is if (100,200,300) combo and (100,201,300) combo have the same count, they should both be ranked the same.
I think this involves performing the rank() function on the count(), for which i was not able to write an SQL. Any help in this direction is appreciated.
Thanks,
<cfdoubt>
PS : Pardon the alignment--i hope you can make out what i mean

Hi Joseph
Hope this query satisfies your Need
Select f_a,f_b,f_c,cnt,     dense_rank() over(order by cnt desc) rk
From (
select f_a,
     f_b,
     f_c,
     count(*) cnt

100 200 300 5 1

ImageIcons in a JLabel get their top-most row of pixels cut off

Hello. I've added a "Loading..." screen to my application that basically consists of a JWindow with a background image. However, I've noticed something odd when adding an ImageIcon to a JLabel. It seems that any image I add gets its top row of pixels cut off. The small program below illustrates this.
import javax.swing.*;
import java.awt.*;
public class JLabelTest {
   static final String WINDOW_IMAGE = "my_image.jpg";
    * Create and display the loading screen
   private static void displayLoadingScreen()
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            JWindow winLoadingScreen = new JWindow();
            ImageIcon loadingImg = new ImageIcon(WINDOW_IMAGE);
            JLabel lblImage = new JLabel(loadingImg);
            winLoadingScreen.getContentPane().add(lblImage);
            winLoadingScreen.pack();
            System.out.println("label dimensions:      " + lblImage.getSize().width + " x " + lblImage.getSize().height);
            System.out.println("image icon dimensions: " + loadingImg.getIconWidth() + " x " + loadingImg.getIconHeight());
            winLoadingScreen.setLocation(100, 100);
            winLoadingScreen.setVisible(true);
    * Entry point
    * @param args
   public static void main(String[] args)
      SwingUtilities.invokeLater(new Runnable() {
         public void run()
            displayLoadingScreen();
}(Obviously, replace my_image.jpg with something else if you'd like to run the code on your own machine.)
When I run the program with, say, an 800 x 600 resolution image, the output I get is:
label dimensions:      800 x 599
image icon dimensions: 800 x 600As you can see, the image gets "shortened" by one pixel when added to the JLabel. If you look at the image that is displayed, you can see that it's the top row that gets cut off. I've tried changing the layout of the JWindow that the JLabel is being added to, but that didn't change anything. I've tried using a number of different images in varying formats, and the same thing happens to all of them.
Any ideas? Thanks in advance.

Have you tried to set label's preferredSize manually?
What happens when you add empty border t the label with some insets?

Stas

Select top 10 rows for each product

Hi,
I have to build a query in the following way:
I have a query like,
select dept, product, product_sold
from products
order by 1, 2 desc
But I have a requirement, not to show all the products in dept . I need to show only first 10 rows of each 'dept' column.
Please help me in acheiving this.

You would do something like this (untested):
select dept
, product
, product_sold
from (
   select dept
   , product
   , product_sold
   , row_number() over (
      partition by dept
      order by product
      , product_sold
   ) rn
   from products
where rn <= 10;Assuming that I have correctly guessed the ordering you require...

I want top 3 called_number as per call_cnt
KINDLY HELP
Thanks

i don't remember about row_number function in 8i, but you can check it :
with t(customer_id ,called_number ,call_cnt) as (
select 10052,         '98256564666',    52 from dual union all
select 10025,         '5985565652',   30 from dual union all
select 10025,         '59855656521',   40 from dual union all
select 10052,         '655465464645',   60 from dual union all
select 10052,         '655465464641',   10 from dual union all
select 10025,         '54654646465',    40 from dual union all
select 10052,         '56546546646',    58 from dual union all
select 10025,         '87422121212',    35 from dual )
select q.* from (
select t.*, row_number() over (partition by customer_id order by call_cnt desc) rn from t
) q
where q.rn <= 3

Selecting top 10 rows based on one column.

Hi,
I need to display the top 10 records for each distinct value of a column.

USE Northwind;
-- Solution 1
SELECT S.SupplierID, S.CompanyName, CA.ProductID, CA.UnitPrice
FROM dbo.Suppliers AS S
CROSS APPLY
(SELECT TOP (10) *
FROM dbo.Products AS P
WHERE P.SupplierID = S.SupplierID
ORDER BY UnitPrice DESC, ProductID DESC) AS CA
ORDER BY S.SupplierID, CA.UnitPrice DESC, CA.ProductID DESC;
-- Solution 2
WITH C AS
SELECT S.SupplierID, S.CompanyName, P.ProductID, P.UnitPrice,
ROW_NUMBER() OVER(
PARTITION BY P.SupplierID
ORDER BY P.UnitPrice DESC, P.ProductID DESC) AS RowNum
FROM dbo.Suppliers AS S
JOIN dbo.Products AS P
ON P.SupplierID = S.SupplierID
SELECT SupplierID, CompanyName, ProductID, UnitPrice
FROM C
WHERE RowNum <= 10
ORDER BY SupplierID, ProductID DESC, UnitPrice DESC;

2)

i wanted to know about the correctness of my sql.
so please tel me which one is correct . or both are correct.You said both give the results you want, so both are correct.
The ways Solomon posted are also correct, and they are better, because they are faster and/or easier to maintain.
and specially about one extra bracket which i have in my 2) stmt.What do you see as the advantages and disadvantages of the 2 ways you posted?
If 2) is better than 1), wouldn't this be even better han 2)?

How to show 10 bottom rows instead of showing 10 top rows of table as defau

A table was created with JTable class and JScrollPane class. If you run the following code, it always shows you the top 10 rows, the scrollbar stays at the right-top by default. However, what I want the program to show is the bottom 10 rows (The table has 30 rows totally) and the scrollbar should stay at the right-bottom as default. I should greatly appreciate it if anybody could tell me how to implement this scenario.

Dimension d = table.getSize();
