Nested If loop on Query

Hi All,
Need some help on one of the query I have. I have several conditions to be fullfilled and I need to use if-then-else syntax. However, izzit possible to if -then-else syntax on SAP B1 Query ? I have tried a few times and it returns me with various error. So far only when syntax works for me.
Thank You
Best regards,
Alex

Hi Thanga,
I have tried it out, but it doesn't work. I think there are something wrong wtih the syntax but I cant find the error.

Issues with nested for loops - saving images from a camera

Hi all,
I've written a vi. to capture a specific number of images ('Image No') and save these images, outputted to a folder of my choice. Each image is identified sequentially. However, I wish to do a number of iterations ('Run') of this capture sequence, such that the filename of each image would be 'Filename (Run)_(Image No).png', e.g. run 5, image 10 would be 'Filename 5_10.png'. I have tried a nested for loop for this but I receive an error 'Asynchronous I/O operation in progress' (I've attached a printscreen).
Can anyone assist me in solving this problem? I preiously posted this in machine Vision but got no response (http://forums.ni.com/t5/Machine-Vision/Capturing-image-sequences-issues-with-nested-for-loops/m-p/19...). Please find attached my vi.

Miika,
the problem is not the filenam, but the name of the folder (AHHHHH!). You try to create the same folder in the outer for loop over and over again.... (it is the error message above the '======', not below )

Nested for loop in Xquery

hi all,
I need to implement nested for loop in Xquery, but not able to do. Please help.
Thanks in advance..
Rajan

Nested for loops are simple in Xquery. Here is a very basic example:
Input:
<root>
<FirstLevel>
     <SecondLevel>
          <Value>1</Value>
     </SecondLevel>
     <SecondLevel>
          <Value>2</Value>
     </SecondLevel>
     <SecondLevel>
          <Value>3</Value>
     </SecondLevel>
</FirstLevel>
<FirstLevel>
     <SecondLevel>
          <Value>4</Value>
     </SecondLevel>
     <SecondLevel>
          <Value>5</Value>
     </SecondLevel>
     <SecondLevel>
          <Value>6</Value>
     </SecondLevel>
</FirstLevel>
</root>XQuery:
declare namespace ns0 = "http://temp.uri/OTM";
declare function ns0:NestedForLoop($input as element(*))    as element(*)
     <ns0:Output>
          for $firstLevel in $input/FirstLevel
          for $secondLevel in $firstLevel/SecondLevel
                return
              <element>{ $secondLevel/Value/text() }</element>
     </ns0:Output>
declare variable $input aselement(*) external;
ns0:NestedForLoop($input)Output:
<otm:Output      xmlns:otm="http://temp.uri/OTM">
     <element>1</element>
     <element>2</element>
     <element>3</element>
     <element>4</element>
     <element>5</element>
     <element>6</element>
</otm:Output>Of course, this case is very simple and usually you wont even loop for this you can use a simple XPath like $input/FirstLevel/SecondLevel/Value/text() to achieve the above result. So, If you are having problems in a specific case of nested for loops, please post the input and output here and we can help out.

Nested For Loop Trouble?

Ok I need to have a nested for loop that asks a user to enter in a int number from 1-50. Whatever the number is, lets say 4 I need the program to count up asterisk and count down asterisks, like this.
This is my code:
import java.io.*;
public class Stars {
     static int n;
     static private InputStreamReader in = new InputStreamReader(System.in);
     static private BufferedReader br = new BufferedReader(in);
     public static void main(String[] Args)throws IOException
          System.out.println("Please enter in a number to see display: ");
          String num = br.readLine();
          n=Integer.parseInt(num);
          for(int i=1;i<=n;i++)
               for(int j=1;j<=i;j++)
                    System.out.print("*");
               for(int j=1;j<=i;j--)
                    System.out.print("*");
               System.out.println();
Can someone tell me what I am doing wrong so I can figure out my mistake(s).

Ok, well I know that the loop relies on the number entered in by the user. So if i pick 3 the three enter in the loop and counts up in a for loop and for every number it counts up to the three it does a print("*"); Now what I am getting confused about is where the other for loop comes into play. I know that I need to start from the number I have which is 3, so I need to have one less than that and then count down. The thing is that i'm not sure where or how the second for loop gets implemented into the code. Does it get nested with the first loop like this:
for(int i=1;i<=n;i++)
               for(int j=1;j<=i;j++)
                        for(int j=n-1;j>=i;j--)
                    System.out.print("*");
               System.out.println();
          }Or is the second for loop on its own like this:
for(int i=1;i<=n;i++)
               for(int j=1;j<=i;j++)
                    System.out.print("*");
               for(int j=n-1;j>=i;j--)
                    System.out.print("*");
               System.out.println();
          }If someone can help me understand, for this is my first time with nested for loops.

Interrupting Nested For Loops/Sequences

I have a lagre program consisting of nested for loops and case statements calibrating an array of patch antennas. The entire process of which will take about 15 hours. During this time, I want to have two things happen.
Every 20 minuites or so, I want the process to stop what it's doing, follow certain commands for the measurement equipment to recalibrate itself, and then go back to what it was doing.
I also want to protect it against unpredicted and predicted crashes. If the system needs to stop for whatever reason, I would like to be able to pick up the process where it left off. A sort of checkpoint system, where, when it passes a checkpoint, if it needs to be restarted, I can tell it to start from the last checkpoint it passed.
Anyone had any experiece with these types of problems?

Could you open and append parameters to a file? Every time you restart execution of the vi after crashes you can look through the contents of the file to determine the last operation that was successful and continue with the last know good settings. -SS

Multiplication Table with Two Nested For Loops

I am trying to code a multiplication table in which the user enters the number of rows between 2 and 10 and enters the number of columns from 2 to 10. This must be in nested for loop format somewhat like this:
rows has been assigned the input variable for rows and columns is the name for input value for columns
for (int i = 1; i <=rows; i++)
for (int j = 1; j <=columns; j++)
i * j
i can't figure out how to get it to print out in table format or if the calculation coding is correct. can anyone help me please?
it should look like this for rows is 4 and columns is 7
1 2 3 4 5 6 7
2 4 6 8 10 12 14
3 6 9 12 15 18 21
4 8 12 16 20 24 28

Nested for loops

Sorry to bother you all, but I have a small problem with my java homework.
I have to make a nested for loop to produce the following output:
00
10 11
20 21 22
30 31 32 33
(only goes from 0 to 3)
Now, all I have managed to do are two simple loops, one with increment 10 and the other with increment just ++.
Could you help me?

Think through this logically. You need two loops. You need this output:
00
10 11
20 21 22
30 31 32 33
Each number above has two digits (two digits, two loops...not a coincidence). So you need one loop to control the first digit, and another loop to control the second digit. Look at the values for the first digit: 0,1,2,3. Those are your first loop values. Now, each time the first loop has a value, your second loop goes through all of its values. Here's the values you need:
First iteration:
loop index 1: 0
loop index 2: 0
Second iteration:
loop index 1: 1
loop index 2: 0,1
Third Iteration:
loop index 1: 2
loop index 2: 0,1,2
Fourth Iteration:
loop index 1: 3
loop index 2: 0,1,2,3
Notice the pattern for loop 2? Look at the starting value for each iteration, and notice the ending value. That gives you your loop constraints.

Parsing is totally wrong. You function processXML() should be like that:
function processXML(e:Event):void
          slideData = new Array();

          loader.removeEventListener(IOErrorEvent.IO_ERROR, loadError);

          myXML_Container_Length = myXML.children().length();
          var node:XMLList;
          for (var j:Number = 0; j <= myXML_Container_Length - 1; j++)
                    id_cont_array.push(myXML.containerss[j].@id);
                    node = myXML.containerss[j].children();
                    myXML_textField_Length = node.length();
                    for (var k:Number = 0; k <= myXML_textField_Length - 1; k++)
                              switch (node[k].name().toString())
                                        case "textfield":

Trouble with nested foreach loop

I got 3 nested foreach loop but the 2nd and the third one outputs no data.
$vss = "vSwitch3"
$vmhost_array = @("host1,host2,host3")
$vss_vlan_array = @("vlan50")
$dvs_vlan_array = @("n1kv_vms_vlan50")
foreach ($vmhost in $vmhost_array) {
foreach ($vss_vlan in $vss_vlan_array) {
foreach ($dvs_vlan in $dvs_vlan_array) {
Get-VMHost $vmhost | Get-VirtualSwitch -Name $vss | Get-VirtualPortGroup -Name $vss_vlan | Get-VM | Get-NetworkAdapter | Set-NetworkAdapter -Portgroup $dvs_vlan -Confirm:$false
I get runtime error at Get-VirtualSwitch -Name $vss
$vss says vlan50 not found. but its there. anything wrong with this nested foreach?

hi
I am actually getting an error on
Get-VirtualPortGroup -Name $($vss_vlan_array[$i])
Its trying to give me the whole array instead of the 1st item in the array. so get-virtualportgroup will fail.
I checked it with $vss_vlan_array[0] and gives me
"vlan50","vlan49"
how do one item at a time instead of the whole array?

Beginner Question: Won't execute index to nested while loop

Problem:
I have a nested while loop inside a for loop. The for loop runs over and over from 0 to 587. I want the while loop to only execute when the for loop hits 587 by means of a continue condition which is on when 587 = [ i ], the for loop iteration number. However when I try to change the value sent to the while loop from 588 none of the probes execute. This is bad because the index only runs from 0 to 587 and never equals 588.
Context:
This is for real time video analysis. Trying to convert a 658 x 492 color video feed frame by frame into low resolution grayscale video. With this index error the output is currently the top left 1/4 of the image, repeated in a 2x2 grid on the image display.
The VI is attached. I'm very appreciative of your thoughts on this.
Attachments:
Bin.vi ‏237 KB

The for loop is responsible for processing a frame. At the completion of the execution of [ i ] from 0 to 587, the replace array VI outputs the final product of the frame. So every time [ i ] = 587, the replace array VI needs to send its array to the arraytoimage, which in turn must send the image to the image display.
I got rid of the while loop and replaced it with the case structure.
Maybe the problem is with the false case of the case structure? I want to continue outputting the same image for the next [0, 586] each time after it sends an updated image on the [ i ] = 587 iteration.

How to LOOP SELECT Query in Oracle?

Hello
I have a query which use a variable (:enddate) and returns a set of data. Lets assume it gives sales totals by account for a given month (specified using the variable :enddate). So the query would look something like :
SELECT ACCOUNT_NO, SUM(SALE_AMT) TOTAL_SALES FROM SCHEMA1.SALES_LINES, :ENDDATE as END_DATE WHERE SALE_DATE BETWEEN addmonths(:ENDDATE,-1) and :ENDDATE
GROUP BY ACCOUNT_NO
Now, currently, I have to run this query each time I need results for a particular date, and thats OK but the problem arises when I need to run this query for an entire year. Then I have to run the query 12 times, passing the date variable each time and re-running the query.
What I would like to do, is to create a loop which covers a time period entered by the user (e.g. user enters 12 months as the total time and 1 month as the period, and the query automatically runs for the previous 12 months, passing :enddate 1 month at a time and then presents the combined results) OR takes a bunch of dates entered in an array, (e.g. :enddate in (JAN-31-2009, Feb-28-2009, MAR-31-2009, APR-30,2009 etc) and runs the query for each of them and presents the results together in one set.
How can I do this using a simple PLSQL loop? I would like to avoid creating a procedure if possible. Sample code will be much appreciated.
BTW, I am using Oracle XE 10g.
Thanks

Hi,
It will be more efficient to get all the results at once, rather than running 12 separate queries.
You can do that without loops or PL/SQL, something like this:
SELECT    account_no
,       TRUNC (sale_date, 'MONTH')     AS mnth
,        SUM (sale_amt)          AS total_sales
FROM        schema1.sales_lines
WHERE       sale_date     > ADD_MONTHS (:enddate, -12)
AND       sale_date     <= :enddate
GROUP BY account_no
,            TRUNC (sale_date, 'MONTH')
;Of course, you can do a query like this within PL/SQL if you need to.
If you'd care to post some sample data (CREATE TABLE and INSERT statements) and the results you want from that data, then I could test it.
Simplify as much as possible. For example, instead of 12 sepaarte months, you can post just 2 or 3. Adapting the solution for 12 months should be easy.
In pure SQL, bind varibales can't be DATEs, but you could define the bind variable as a string and use TO_DATE to convert it to a DATE, OR use a substitution variable instead of a bind variable.
The solution above works in all versions Oracle. The way you're using :enddate in the FROM clause, and a function called addmonths (rather than ADD_MONTHS) makes me wonder if you're using Oracle at all.

ORA-00935: group function is nested too deeply - SQL Query is correct...

select s.sname, to_char(sum(t.amount), 'fm$999999.00')
from transactions t, salespeople s
where t.sid = s.sid
group by s.sname, t.year
having (t.year = 1997) and max(sum(t.amount));
I'm trying to print sales person name who had the highest total sell in 1997. I do not see where did i go wrong in the above query...Isn't nested group function allowed?!
What about this?
select s.sname, to_char(sum(t.amount), 'fm$999999.00') as "TOTAL"
from transactions t, salespeople s
where t.sid = s.sid
group by s.sname, t.year
having (t.year = 1997) and sum(t.amount) = (select max(amount) from transactions where year = 1997);
It should return something, but it does not due lack of data in database. I think the above code is correct. I just need to confirm from you...

select s.sname, (case when sum(t.amount) > sum(t2.amount)
then sum(t.amount)
else sum(t2.amount)
end) "TOTAL"
from transactions t, salespeople s
where t.sid = s.sid
group by s.sname, t.year
having t.year = 1997
union
select s.sname, sum(t2.amount)
from transactions t2, salespeople s
where t2.sid = s.sid
group by s.sname, t2.year
having t2.year = 1997;
Your code looks good, but it does not work in Oracle Developer...
The above should work isn't it? The inner query gets executed then the outer one so the result i get in

A nest within a nest and the multiple-query blues...

Hi all:
Complex problem here, so bear with me please. I'm still
building this corporate database for purposes of inventory
tracking, and my latest problem follows. Here's the setup.
I have a MySQL database with 3 tables (there are actually
more, but those are the only ones that are relevent):
units_main' stores information about machinery such as its
model number and invoice number.
di_options_main' keeps track of what accessories are added
to a given unit through the use of a foreign key, in this case an
auto-generated integer called 'unit_id' which is primary in
units_main and secondary in this table.
valid_options stores the values such as manufacturer and
type for the accessories mentioned earlier, linked through the
common key of 'model_number'.
Now I have a searching engine which brings up a standard
results page (a regular table with a repeating recordset) of all
units matching the given search criteria. I want to be able to look
at this search results page and see not only the data retrieved
from the units_main table, but also some of the related data in
di_options_main. For instance, suppose I have an L3400 tractor with
an LA703 loader. The tractor is listed in units_main, while the
loader is found in di_options_main. I could create one recordset
for the main tractor data and one for the loader (option) data, but
this screws up the repeating recordset. Further, in this case, the
data needs to be retrieved from di_options_main based on the 'type'
field of valid_options - I only want to see accessories of the type
'LOADER'. This puts the query about three generations back. I might
still be able to code this if it weren't for the repeated region,
which can't be nested and throws a wrench in the works. I know this
is a difficult question, but I can post code for one or all the
files involved if it sounds like something someone can help me
with. Thanks in advance.

What you need to do is join all the tables into a query in
the database,
then use this as a source for the recordset on the page. You
need to use
nestes repeat regions to display the detail information.
Depending upon the
server language you are using there are extensions that can
do this for you.
