Finding the max value using partition by

Hi
I've the following requirement where i need to select the max value from the data
WITH T AS
(SELECT 48003 ID ,'SPR' RTNG_TP_CD , 'INS' RL_CD ,'A-' RAT_CD FROM DUAL UNION ALL
SELECT 48003 , 'SLNG' ,'INS','A-' FROM DUAL)
SELECT distinct ID, RTNG_TP_CD,RL_CD,MAX(RAT_CD) over (partition by id) RT_CD
FROM T
For a single id if there are 2 RTNG_TP_CD then select the max(rat_cd) by displayin rtng_tp_cd =SLNG
Expected Output
48003 , SLNG , INS , A-Thank You

WITH T AS
(SELECT 48003 ID ,'SPR' RTNG_TP_CD , 'INS' RL_CD ,'A-' RAT_CD FROM DUAL UNION ALL
SELECT 48003 , 'SLNG' ,'INS','A-' FROM DUAL)
SELECT distinct ID,decode((select count(*) from t where id=t.id),1,RTNG_TP_CD, 'SLNG') RTNG_TP_CD,RL_CD,MAX(RAT_CD) over (partition by id) RT_CD
FROM T

Finding the max value

Hi team,
I have the following query where i need to find the max value
[code]
with t as (
   select 'L1' R_nm ,'Data' R_Data , 'Obj' R_Obj , 'Wd' r_prec , '2' val from dual
   union all
   select 'L1' , 'Data', 'Obj' , 'No', '4' from dual
union all
   select 'L2' , 'Data', 'Obj' , 'No', '4' from dual )
   select t.*, max(val) over(partition by r_nm,r_data,r_obj) rk from t
[/code]
My expected output should be
[code]
r_nm    r_data     r_obj   r_prec   val     rk
L1        Data         Obj     Wd       2       1
L1        Data         Obj     No       4        2
L2        Data         Obj     Yes      1       1
[/code]
Thank You

Hi,
It looks like you're not interested in the MAX at all. It looks like you want to rank the rows, such that the one with the lowest value is assigned the number 1, the row with the 2nd lowest values gets 2, ..., and the row with the N-th lowest value gets N. If doesn't matter if the MAX is 4, or 2, or 420.
Here's one way to do that:
SELECT    t.*
,         RANK () OVER ( PARTITION BY r_nm, r_obj
                         ORDER BY      val
                       ) AS rk
FROM      t
ORDER BY r_nm, r_obj
,         val
Depending on how you want to deal with ties, you might want to use ROW_NUMBER or DENSE_RANK instead of RANK.

How do I find the max value of scrollV in AS3?

I used Ned's answer to get my 3 text fields scrolling together based on the value of one of them. Thanks Ned!
The other two text fields scroll to match the 'parent' text field, but at the end - as you reach the last scroll position - the other two do not update and the 3 text fields are out of alignment. Its just at the end of the scroll. The rest of the scroll values align. I'm thinking if I can find the max scrollV value, I can force the other two to scroll one last time when that value is reached by the 'parent' text field.

Thanks Rob! I knew it must be something available somewhere. That should allow me to do the needed calculations. Awesome.

Couple of points about your code:
1. Don't declare your instance variables as solid types, declare them using their interfaces (where applicable), so in your case don't specifiy that you are using Vector or Hashtable, use List and Map. This will allow you to easily change your code to use a different collection, if and when appropriate. Also the unnecessary overhead of Vectors synchronisation means that you should use ArrayList instead of vector (that means that you will have to use get(int) instead of elementAt() but that's a very small price to pay.
2. Declare local variables as close to their point of usage as possible. (Unless you need to do this for your course work, in which case you don't have a choice).
3. Use the appropriate data type. For your count of null values you should be using an int or a long (you can't have a fractional count value!) Also, this should have been obvious to you, when you had to cast the value to an int for use with your lists. (Using double as an index is a very bad idea... And before you go posting the question, do a search on why floating point precision may not give you the results you expect)
4. Code defencively... e.g. in your meanDouble() method, you set nonNull to 0, and then you do a division using that value. What do you think is going to happen if your loop doesn't execute once? Division by zero... You should handle these cases, rather than letting them fail ignominiously.
5. If you are doing code like this...    if (currentDouble != null) {
        // / nothing to do
    } else {
        nbNull++;
    } Why have the empty block? You should just do the inverse.
    if (currentDouble == null) {
        nbNull++;
    } Far simpler, and expresses exactly what you are trying to do, not what you are not trying to do.
6. Enumeration --- What version of java is that course being run in? I can see that you are using autoboxing, so it has to be 1.5 so, WHY is your lecturer encouraging the use of Vectors, Hashtables, and Enumerations!?!?!
Anyway, that should be enough to be going on with.

How to find the RGB Values of a Color for Hyperion

When customizing your Hyperion forms, we come across situations where we need the exact RGB value of a given color. This article explains a simple technique to find the RGB values using MS Paint and the Calculator applications that come as standard applications with your operating system.
Here are the steps to find the exact RGB value of a given color.
1) View your Hyperion form using IE, scroll down until you see the color you want to find the RGB value and press the "Print Screen" button (in your keyboard).
2) Open MS Paint and click Edit -> Paste or simply Ctrl+V. What you saw in the browser will be copied as a new untitled image.
3) Select the Color Picker tool and click on an area that has the color you want to match.
4) Now go to Edit Colors... option and click on the "Define Custom Colors >>" button. The color you picked will be selected on this palette. At the bottom right hand corner you will see the Red, Green and Blue values you need. Note down the R,G,B values (given in decimal).
5) Now we need to find out the hexa-decimal values that correspond to those decimal values. This is where we use the simple Calculator. Open the Calculator application from Program -> Accessories. Switch to the scientific mode by clicking View ->Scientific.
6) By default it will be in the decimal number mode. Enter the R value (238 in this example) and click on the Hex radio button. The corresponding hexa-decimal value (EE in this case) will be shown in the dial.
The selected color in this case has the same value for R, G and B. (In fact, all shades of gray has the same values for R, G and B.) Therefore, the RGB value of the background color that we need is #eeeeee. Repeat step 6 to find out the hex value for the Green and Blue elements, if they are different.
Tip:
If you find it difficult to pick a color, zoom the image by pressing Ctrl+PageDown or using View -> Zoom -> Custom... option.

These tips are to find the RGB color of HFM default row where row is text and text lines in data columns are also visible to business users as Yellow as an input cell. By applying the same RGB color you can apply the same color to your data cells or rows. This post shows how to identify color from any web view-able object.

How to find the maximum value among four fields in a single record

Hi Gems...
I have a record in which there are 4 currency fields.
Now i would like to know the maximum of these 4 fields.
I tried with Max functions in which i put all the 4 values...but it is showing error like ") is missing" though it is there.
Can we insert more than 2 values in Max function?
Or else is there any other option to find the max value among the 4 values which lies in a single record
Thanks
Jiten

Hi Anil,
Say suppose i have a single record in which 4 premiums of a particular bond exists.
for eg:
Prem1 Prem2 Prem3 Prem4
129000.00 388000.00 228000.00 14800.00
Now this is a single record for a particular bond ... now i need to calculate the max value among these 4 premiums.
How would we proceed to achieve this?
Regards
Jiten

I have multiple bpel in my composite. I checked in ci_indexes table and it shows the instance number of the bpel process. But the em console is showing only the composite instance number. when I opened composite instance, I could see all the bpel process with instance number in the audit trail. How can I find the the actual composite instance number that I should search for in the em console ???

Finding the largest values of an array without using if condition

Hi,
I am trying to find the largest values of an array without using any if condition. Can any one tell me the solution for that..
Thanks

I am trying to find the largest values of an arrayThe 'S' to values suggests that you want not only the largest one, but multiple ones among the largest ones. The best way, I think, is to sort the array, so that its largest values are grouped topgether. If the type is already Comparable, the following single line does the job:
Collections.sort(myArray);After this, the last values of the array are the largest ones.

How to get the max value of a set of percentage values?

Hi,
I've tried to get the max and min value of a set of calculated percentage values. Such as
Jan Feb March Apr May Jun Min Average Max
0,5 0,8 1,1 0,4 1 0,6 0,4 0,7 1,1
The average value works fine. But with "min" and "max" I have a problem.
I've tried to get the value with the following ways:
- Create a new calc. keyfigure and make a sum of all values: (Jan + Feb + ...) and set the calculation in key figure properties to Min/Max.
- Create a new calc. keyfigure and make a sum of all values and set the aggregation to Min/Max
- Create a selected keyfigure with a filter to the necessary periods and set a calculation to Min (Aggregation is not possible here)
- Create a new cal. keyfigure with all periods and the function Min. e.g. min(Jan, (min Feb, (min (....)
None of this solutions provides the right min and max value. When I use an amount value (e.g. Euro) instead of these percentage values the keyfigure with the min and max function works. The others all provide wrong values.
Is there a solution to get the right min and max value???
It would be a great help when you have any hints.
Thanks
Claudia

Hi Aduri,
thanks for your answer but your solution doesn't work.
The problem is that the periods are defined in a structure with offsets such as
- period-11
- period-10
- period
in this structure elements there is also the keyfigure "netvalue" defined.
In the rows of the report there is another characteristic such as company code.
Is there a solution to find the max and min values of the period values for each company code? Or must I change the data model e.g. copy the keyfigure and make a new keyfigure with another aggregation level?
Thanks for any hints!

Finding the largest value...

Hi guys,
I'm creating a method where it finds the largest value in a list of integers, using a loop. When it finds it, it's stored in the "max" and returns the "max".
Here's the code...
    public Integer findMax()
        List<Integer> list = Arrays.asList(4,8,2,10,24);
        int max = 0;
        for(Integer i = 0 ; i < list.size() ; i++) {
            if(max == list.get(i))
            max = i;
        return max;
    }It complies, but when i run it, it doesn't actually get the largest value (which should be 24). It's still 0 when i Inspect it.
Does anybody know where i'm going wrong with this?

Well i went through the method and it seems to be printing 0 five times...
    public Integer findMax()
        List<Integer> list = Arrays.asList(4,8,2,10,24);
        int max = 0;
        for(Integer i = 0 ; i < list.size() ; i++) {
            if(max >= list.get(i))
            max = list.get(i);
            System.out.println(max);
        return max;
    }After looking looking through the API, i used the length, instead of size, but when i compile the program it says it can't find the method. Do you know what else i have to change or add in the code for it to compile?

if(max == list.get(i)) Can you explain, in words, what this comparison was meant to do?I've edited that, because that's wrong.

How to retrieve the max value from a cursor in procedure

Hi,
In a procedure, I defined a cursor:
cursor c_emp is select empno, ename, salary from emp where ename like 'J%';
but in the body part, I need to retrieve the max(salary) from the cursor.
could you please tell me how I can get the max value from the cursor in the procedure.
Thanks,
Paul

Here is one sample but you should just get the max directly. Using bulk processing should be a last resort.
DECLARE
CURSOR c1 IS (SELECT * FROM emp where sal is not null);
TYPE typ_tbl IS TABLE OF c1%rowtype;
v typ_tbl;
max_sal number;
BEGIN
OPEN c1;
max_sal := -9999999999999;
LOOP                                                 --Loop added
    FETCH c1 BULK COLLECT INTO v LIMIT 3; -- process 3 records at a time
        -- process the records
       DBMS_OUTPUT.PUT_LINE('Processing ' || v.COUNT || ' records.');
        FOR i IN v.first..v.last LOOP
             if v(i).sal > max_sal then
               max_sal := v(i).sal;
             end if;
            DBMS_OUTPUT.PUT_LINE(v(i).empno);
        END LOOP;
    EXIT WHEN c1%NOTFOUND;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Max salary was: ' || max_sal);
END;

How to find the PREVIOUS value of a non-DB item?

I want to do a simple thing but found it impossible.
I want to find the previous value of a non-DB item in a form.
I tried creating a text item and populating it using PRE-TEXT-ITEM but that does not work.
WHEN-VALIDATE-ITEM does not work either because WVI fires only after item value has changed.
Any suggestions will be greatly appreciated.

How to find the nearlest value in 1-D array ?

Hi.. everybody..
I need to seperate the raw data(1-D) into 2 group of array by the center value and then make the average value in each array. But I also still have the problem about if the center value is not the same of some value in the 1-D array. I cannot use the split function.
"How to find the nearlest value to the center point that I calculated, in the 1-D array ?"
Thanks a lot for anybody help

In a general sense, since I'm not sure what your data values are or how far away your calculated center is from the true value, I would do it one of two ways:
1) Use a threshold value and scan the array until the threshold is reached (assumes constantly increasing values in the array).
2) Use either a) round to nearest integer b) round to + Infinity (round up) or c) round to - infinity (round down). If you don't have decimal values, you'll have to devide the values by a power of 10.
