Hi jyotia,
in this thread you'll find the functions to read the entire content from your excel file. If you have your data as an array in LabVIEW, then you can use the "Array Min&Max" function to get the min index from your column "B". With index array you can read the corresponding value from column "A".

Read integer values from spreadsheet and display the values in a table

Hi all,
I have integer values to read from a spreadsheet and display them in a table. I am using 'Read from spreadsheet file' in 'integer' mode. I would like to display these values in a table. The problem is that the table takes only 2d-array of string as input but not integer.
It works fine if I change the mode of 'Read from spreadsheet file' from 'integer' to 'string' but I want to read integers and have to use the integer values for further calculations. Please give any suggestions on displaying integers to a table.
Thank you.
Solved!

No don't take element by element just convert as a whole. See the attached example
Good luck
The best solution is the one you find it by yourself

Get the minimum value from a cursor

Hi,
i have a cursor that returns the following two columns in a stored procedure. now i want to find the minimum value of SORT NUMBER column .
Can anybody give me an idea.....
create or replace procedure get_min
as
cursor c1 is
select group_number
       , sort_number
from group_table
v_min number;
begin
for c1_rec in c1
select min(c1_rec.sort_number) into v_min ;
end;
GRP_NUMBER            SORT NUMBER
1001                           9978
1002                           9979
1003                           9946   thanks in advance.

OPTION1
I'm guessing your stored procedure loops through the cursor (goes record by record and does something), correct? If it loops through all records, then
1. first define variable which will hold minimum value e.g.
my_min_value number := 0;
2. then add this inside the loop (as you loop through all records, my_min_value will get assign the lowest value)
my_min_value := LEAST(my_min_value, c1_rec.sort_number);
when the cursor is done looping through all records, you get your minimum value
small note: make sure c1_rec.sort_number is not null or you know how null works with least function
OPTION2
if you don't loop through all records (maybe have a condition and stop looping), then you can always change the SQL and add the minimum value to the SQL, there are multiple ways to do this, this is one of them - I hope there is no typo - it's 8pm :-)
select group_number
       , sort_number,
          min(sort_number) OVER ( )
from group_table
OPTION3
get rid of cursor, there are probably 5000 better choices :-)

Finding unique minimum value from a set of values

Hi.
I have numbers in three columns - H, P, X
I need to compare numbers in each row and find out the lowest value and find out if there is a unique lowest value.
For example, in row 2
H2=2, P2=5.4, X2=2. In this row, both H2 and X2 have the lowest number, 2. Hence, the lowest number is not unique. I want to fill cells H2 and X2 in Yellow and cell P2 in Red.
In row 3,
H3=2, P3=5.4, X3=4. In this row, H3 has the lowest unique number, 2. I want to fill cell H3 in Green and cells P3 and X3 in Red.
Green = lowest and unique
Yellow = lowest but not unique
Red = Not the lowest
I can use the MIN function to find the least number but I do not know how to identify the unique lowest number if available.
Thanks for your help.

Select for example H2:H100. I will assume that the active cell within the selection is in row 2.
Color the cells yellow (this will be the default)
On the Home tab of the ribbon, click Conditional Formatting > New Rule...
Select 'Use a formula to determine which cells to format'.
Enter the formula
=OR($H2>$P2,$H2>$X2)
Click Format...
Activate the Fill tab and select red.
Click OK, then OK again.
On the Home tab of the ribbon, click Conditional Formatting > New Rule...
Select 'Use a formula to determine which cells to format'.
Enter the formula
=AND($H2<$P2,$H2<$X2)
Click Format...
Activate the Fill tab and select green.
Click OK, then OK again.
The formulas for columns P and X are similar, switching the roles of the three cells.

Use a running total, you can refer to your formula in the running total.

Finding minimum value

I have 4 double variables and I need to find the minimum of them all. I tried using the Math.min (x,y) statement but it only allows me to find the minimum of two numbers. Thanks,
    public static void main(String [] args) {
    double minimum = getMin (4.2, -3.5, 2.1, 1.1);
    System.out.println("The Minimum is: " + minimum);
    public static double getMin (double w, double x, double y, double z)
    double minimum = Math.min(w,x);
    return 0;
    }

> One of the easiest way might be a sorted list
in
which you just grab from the low end.
Sorting the list would be more time consuming than
iterating over it once and returning the smallest
value, as warnerja suggested.I know but it appears that the OP does not want to do any comparisions himself so I was suggesting this.

Finding maximum value from VARCHAR2

Hi all.
I am having Varchar2 values like this....
1.0.0.22
1.0.0.23
1.0.0.3
1.0.0.6
1.0.0.7
1.0.0.8
1.0.0.9
1.0.0.9
I want to find the highest value (in this case, it is 1.0.0.23). If i use MAX function, it is giving 1.0.0.9. Any help is appreciated.
Thanks in advance,
Pal

In 10g, I would use regular expressions to "format" those version numbers. In my example, it would work for 3-digit version numbers, regardles on which position:
WITH t AS (SELECT '1.0.0.22' col1
             FROM dual
            UNION
           SELECT '1.0.0.23'
             FROM dual
            UNION
           SELECT '1.0.0.3'
             FROM dual
            UNION
           SELECT '1.0.0.6'
             FROM dual
            UNION
           SELECT '1.0.0.7'
             FROM dual
            UNION
           SELECT '1.0.0.8'
             FROM dual
            UNION
           SELECT '1.0.0.9'
             FROM dual
SELECT col1
FROM (SELECT t.*
             , ROW_NUMBER() OVER (ORDER BY REGEXP_REPLACE(REGEXP_REPLACE(t.col1,
                                                                         '([0-9]+)(\.|$)',
                                                                         '000\1\2'),
                                                          '([0-9]{3}(\.|$))|.',
                                                          '\1') DESC

Find duplication values from multiple columns in a big table

Hi All,
I am working on a 11gR2 database in linux. i want to display record that have duplicate values in 2 columns.
1. Table Structure :-
CREATE TABLE A
ID NUMBER(10),
F_NAME VARCHAR2(100 BYTE),
L_NAME VARCHAR2(100 BYTE)
2. Sample Data:-
Insert into A
(ID, F_NAME, L_NAME) Values (1,'TONY' ,'SUMIT');
Insert into A
(ID, F_NAME, L_NAME) Values (2,'SUMIT' ,'KEITH');
Insert into A
(ID, F_NAME, L_NAME) Values (3,'NORA','SMITH');
Insert into A
(ID, F_NAME, L_NAME) Values (4,'APRIL','TONY');
Insert into A
(ID, F_NAME, L_NAME) Values (5,'ROSS','TAM');
ID F_NAME L_NAME
1 TONY SUMIT
2 SUMIT KEITH
3 NORA SMITH
4 APRIL TONY
5 ROSS TAM
4. My requirement is i need display IDs that it's F_NAME or L_NAME has duplication in F_NAME or L_NAME columns.
The result should be
ID
1 reason: F_NAME (TONY) equals to L_NAME of record 4, L_NAME (SUMIT) equals to F_NAME of record 2
2 reason: F_NAME (SUMIT) equals to L_NAME of record 1
4 reason: L_NAME (TONY) equals to F_NAME of record 1
record 3, 5 aren't in the result because there is no duplication in F_NAME or L_NAME columns for NORA,SMITH, ROSS, TAM
The table contains 10 million records, i really need to consider the performance.
kindly suggest me the solution

Note: Forum members please suggest better approach to this -- below.. convert into SQL :)
I know I will be opposed by many people in this forum for posting such in-efficient solution.
But trying to learn along with you.. its an interesting problem which must deal with all rows vs all rows to get all combinations.
But I am still thinking how to write it in SQL, probably will learn from this post after we receive some good SQL solution for the code what I am currently doing now.
step 1: created a table B similar to table A and added a column reason
CREATE TABLE B
ID      NUMBER(10),
F_NAME VARCHAR2(100 BYTE),
L_NAME VARCHAR2(100 BYTE),
REASON VARCHAR2(1000 BYTE) --- ADDED THIS

How to extract values from pricing procedure for conditions in CRM Billing?

I have a number of conditions in the pricing procedure in CRM Billing that I would like to extract to SAP BW. How can this be done?
Is there a standard extractor for CRM Billing similar to the SD Billing extractor "Extraction of SD Billing Conditions" (2LIS_13_VDKON)?
If there is no standard extractor, is there another way to extract the conditions and the related values?
I am using the standard CRM Billing Extractor 0BEA_CRMB already, so maybe an append could solve my problem. How can this be done? In what CRM-tables can I find the values from pricing procedure for conditions in CRM Billing?

you may want to post that last question in a CRM forum... in ECC it would be table KONV

How to capture the data within the given range of maximum and minimum values ? from csv files

My requirement,
1. Here, the user will provide the range like maximum and minimum values, based on this range, the VI should capture the data within the given range. ( from CSV file as attached )
2. Then VI should calcluate the average value for captured data and export it to excel.
This is my requirement can anyone help me on this.
Many thanks in advance

Hi,
Thanks for remnding me. I forgt to attach the VI,
Here I am attaching the VI, what I tried.
From attached CSV file, I have to find an average value for columns B,C,D,E,F,G,H,I and AJ, AK. ( data range will be defined by user ), focused only on these columns
Here, the scope is to calculate an average value for given data range by user as MAX and MIN data.
FYI: I tried manually for two instance i.e column H & I. As per H column one steady state values from 7500 to 10500 and similarly in I column 7875 to 10050. So, I gave these as a limit to capture and calculate the average value. But unfortunaltely, requirement has been modified as per below requirements.
More Info on requirement:
--> The user will define the range of data by giving some MAXIMUM and MINIMUM values(for above mentioned columns induvidually), then VI should capture that data range and it has to caculate the average value for that range of data. This is the task I have to complete.
--> I am stuck in creating a logic for data capturing for given range of MAX and MIN value from user,
Can anyone help me on this.
If my explanation is not clear, Please let me know.
Many thanks, help mw

How do I make a drop down list of text in numbers as it is made in the example spreadsheet for comparing cars for buying where you can choose a value from a dropdown list for each car?

how do I make a drop down list of text in numbers as it is made in the example spreadsheet for comparing cars for buying where you can choose a value from a dropdown list for each car?

Where is this example spreadsheet? Without seeing it I can only guess at what you are asking.
To make a drop-down list (a pop-up menu in Numbers-speak), format the cell as a pop-up then edit and add to the list of items.
If the example spreadsheet is pulling in a dollar value based on what car you chose in the pop-up, it is probably using LOOKUP or one of the other lookup functions, getting the information from another table (a lookup table). If, instead, these dollar values are what you are choosing in the pop-up, then you need to create a pop-up with these values in it.
The Help menu includes a link to a page where you can download the Numbers Users Manual. It also has a link to the Formulas and Functions guide. Both are useful to new users.

Finding a minimum value in an array without using loops

I can find a minimum value in an array using a loop, but I am unsure of how to do it without any type of of loop
Here is what I have using a loop:
// This method searches for the minimum value in an array
public static int min(int a[]){
int min = a[0];
for(int i = 1; i < a.length; i++){
if(a[i] < min){
min = a;
return min;
How do I covert this to do the same thing, using no loops?
Thank you for replies
