• Creating tables in a nested for loop

  Hi all.

  I was stuck in this problem for quite a while now and I still don't know how to continue. Some outside the entrance would be greatly appreciated!

  I'm doing the following:

  -Take an array of numbers, to check if they are within a certain range (e.g. between 2 and 4)

  -Build two new arrays: one with all the numbers that are inside the beach and the other with the rest.

  An additional condition is that the amount and value of the range conditions will change (for example, it could be between 2 and 4 only / 2, 4 AND 6 and 7 according to the entry)

  To treat this, I created two nested for loops - one that goes on a table that contains conditions of the beach and inside that actually go and check if the values are in the range. I think I did that part successfully, but the next part is confusing to me - how to actually create the tables separated within two loops for?

  My apologies if I did not explain it well. Another method to support this problem is I want to translate following LabVIEW:

  Ranges of table / / [1 5 7 10] exodus-> This means we want to divide numbers based on those who are in (1,2) and (4.5) against those who are not

  Table of values / / [2 3 6 11 3]

  EndOperationDelegate table / / array of values within the range
  Table outValues / / Array of values out of range

  for m = 1:size (ranges)

  for n = 1:size (values)
  If (THE NUMBER IS on the INSIDE of EACH RANGE)
  EndOperationDelegate = [EndOperationDelegate NEWNUMBER]
  on the other
  outValues = [outValues NEWNUMBER]
  end

  end
  end

  Sounds easy enough, but it gets so chaotic with Labview that I don't know what to do. I have attached a reference image - insertion in the array function is not in fact add to the table, it creates a new table. How can I save that for when the nested for the ends of the loop?

  I have seen a few examples with shift registers which lie in a loop and I couldn't successfully that transfers in my block diagram.

  Any help/direction would be greatly appreciated.

  Hello!

  See the following example to understand how you can create a table in the loop For

  

  In your case, you also can uce conditional terminal to create a table only when then located nearby. It makes the code much cleaner that the structures of the case

  Hope this helps, if not, let me know if I can help you!

• Capture of sequences of images - issues with nested for loops

  Hi all

  I've written a vi. to capture a number of images ("Image") and save these images, sent to a folder of my choice.  Each image is identified sequentially.  However, I would like to make a number of iterations ("run") of this capture sequence, such that each image file name would be "Filename (Run) _(Image_No).png", for example run 5, image 10 'Filename 5_10.png.  I tried a nested for loop for this but I have an error message 'Current asynchronous i/o Operation' (I have attached a printscreen).

  Can someone help me solve this problem?  Please find attached my vi.

  Sincere greetings and thanks,

  Miika

  Hi toto26,.

  Thank you for your response.  I solved the problem by using a sequence structure flat - file in the first image and all the treatment in the second.

  Kind regards

  The analysis is totally false. You operate processXML() should be like this:

  function processXML(e:Event):void
  {
            slideData = new Array();
            loader.removeEventListener(Event.COMPLETE, processXML);
            loader.removeEventListener(IOErrorEvent.IO_ERROR, loadError);
            myXML = new XML(e.target.data);
            voiceOver = myXML.@voice_over;
            startOffset = myXML.@start_offset;
            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":
                                                    trace(node[k].@id);

• Count (*) with the nested query

  Hello
  I have a question about the count (*) with the nested query.
  
  I have a table T1 with these columns:
  Number of C1
  Number of C2
  Number of C3
  Number of C4
  Number of C5
  
  (The type of each column is not relevant for example).
  
  This query:
  Select C1, C2, C3, C4
  from T1
  Group C1, C2
  
  It is not correct becausa C3 and C4 are the columns specified in the GROUP BY expression.
  
  If you run this query:
  Select count (*)
  (select C1, C2, C3, C4
  from T1
  Group C1, C2)
  
  I don't have an error message (properly, the result is the number of records).
  
  Why?
  
  Thank you.
  
  Best regards
  Luca

  because the optimizer rewrites as

  SELECT     COUNT(*)
                FROM   T1
            GROUP BY   C1, C2

• performance for this convoluted nested query

  Hello
  
  I wonder about the performance of this convoluted nested query:
  
  Select t.parentId from TreeParentChild t
  where t.childId =: childId and t.childOwnerId in)
  Select tt.parentOwnerId in the TreeParentOwner tt
  where t.parentId = tt.parentId
  )
  
  There are two tables of interest. The first establishes parent-child relationships,
  and includes the id of the owner of the 'child', which always has exactly one owner.
  
  table TreeParentChild
  ---------------------
  long parentId
  long childId
  long childOwnerId
  
  The other table lists of owners for the 'parents' who gave
  parentId can have several owners mapped into multiple lines
  
  table TreeParentOwner
  ---------------------
  long parentId
  long parentOwnerId
  
  And the purpose of the above query is to get all the parentids for a given childid
  who have an owner mapping said that the parentid has an owner that is
  the owner of the child.
  
  This query makes sense to me, but I wonder about his performance, because a column
  external selection corresponds to a column in the internal selection. What is - c
  also called nested request type?
  
  Andy

  Hi, Andy.

  If you are interested in the jargon, a join where you not actually select anything from one of the tables is called a join semi .

  user9990110 wrote:
  ... It must also pin to a childId data so I've rewritten as:

  SELECT     t.parentId
  FROM     TreeParentChild t
  WHERE     t.childId = :childId AND (t.parentId, t.childOwnerId) IN
       (
            SELECT     tt.parentId, tt.parentOwnerId
            FROM     TreeParentOwner tt
       )
  ;
  

  Is this correct?

  Oops! I forgot this condition: it takes only!
  Yes, your correction is correct.

  And what you would like the clues in this case for 2 tables for better performance?

  Similarly, what would you as clues to the two tables for better performance in the case of the solution to join internal you gave?

  For each query, you can use a composite index on t (parentId, childOwnerId) and an index composed on tt (parentId, parentOwnerId).

  There is yet another way to do what you want: an EXISTS subquery.

  SELECT     t.parentId
  FROM     TreeParentChild          t
  WHERE     t.childId = :childId
  AND      EXISTS
       (
            SELECT     0
            FROM     TreeParentOwner tt
            WHERE     tt.parentId       = t.parentId
            AND     tt.parentOwnerId  = t.childOwnerId
       )
  ;
  

  With rare exceptions, EXISTS subqueries are always correlated.

  I suspect that the best way to this is the first way I posted, using a join.

• nested query

  Hello
  I'm stuck in a nested query. My table structure is as below.
  
  create table a1 (varchar2 (10) c1, c2 varchar2 (10));
  create table a2 (varchar2 (10) c1, c2 varchar2 (10));
  
  and my data
  
  insert into a1 values ('1', 'A11');
  insert into a1 values ('2', 'A12');
  
  insert into a2 values ('1', 'A21');
  Insert in a2 (c2) values ('A22');
  
  now when I try to extract all records in table A1 with column C1 not in column C1 of table A2 then returning me 0 documents instead of returning the second disc with c1, c2 as '2', 'A12 '.
  
  Can anyone explain why its happening then?

  Hello

  An explanation for this can be found in the doc below.

  [http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions013.htm]

  If any item in the list that follows a NOT IN operation is null, then all lines are evaluated to FALSE or UNKNOWN, and no row is returned

• Nested while loops

  Attached is a very simple with two nested all VI in loops and two buttons on the front panel.

  1 button, when you press left the inner loop.  2 button pressed leaves the outer loop and the program must end.  I put in a probe at the end of the outer loop and of course a REAL will to the terminator when I press the 2 key, but the program does not stop.  Apparently, all inner loops must be completed prior to the outer loop can terminate.

  Obviously, someone at NEITHER took the decision to design a long time ago, but the rationale is intriguing.  If one end of the loop becomes a REAL it must end, no?

  Although the example is trivial, the problem that it illustrates is a real for me.  I want to offer a panic button stop is a vast and complex and I don't see how I can do with things as they are.

  What you see is the result of the dataflow paradigm used by LV as you said, all the code inside the loop must complete / finish before the outer loop stops.

  Providing one Stop button to stop all in one comprehensive program can be a complex task. The key issue is that EACH loop, function, sub - VI, case structure, structure of the event, the structure of sequence and so on... must stop to stop the loop.  If you have something like a file entry or a reading of GPIB instruments which take 100s of milliseconds or seconds to complete, the shutdown will take at least that long process, assuming that the tedious node was running when the judgment was issued.

  One other point: you put inside terminal 2 touch it the case of the event that responds to the key. Which ensures that the button will be read so the mechanical action works as expected.  With her out of the loop it will only play once.

  A registrant can be used to 'spread the word' when it's time to stop.  The time-out he will keep waiting forever and will also allow the other parallel inside code while loop to run during waiting for him.

• Subselect query returns "invalid identifier", but the nested query return lines

  I don't think it's a general SQL question.

  Select * from persons where person_id in)

  Select person_id with people whose name = 'Obama' - subquery

  ) and age > 18;

  When I run the subquery, I get:

  ORA-00904: "PERSON_ID": invalid identifier

  00904, 00000 - '% s: invalid identifier '.

  * Cause:

  * Action:

  Error on line: column 5: 8

  This is because the table people do not have the person_id field.

  But when I run the nested together query it returns all the lines in people with the AGE greater than 18.

  How is he succeeds when the subquery is obviously wrong?

  Yes - this is a general SQL question and ask often enough.

  Correlated subqueries depend on the inner query, be able to see and access to the columns of the outer query. Normally see you referenced in the WHERE clause of the subquery and not in the SELECT clause, but the reference is valid in both places. This works because the columns of the tables in the main query are accessible in the subquery. "Person_id" is probably a column in the table 'people '.

  Which can be a cause of problems 'odd' when the column (in your case "person_id") is more of a table.

  Use an alias in the subquery in the subquery and you will find that it will not succeed.

  I can select these separate items of data in the table or I can add them to the XML through a local variable. I tried several ways to add this to my above query but am stuck. If I bring to the table, the field names are dailyStartDate, weeklyStartDate and monthlyStartDate. Again, I only want the distinct values and therefore something for everyone in this XML file rather than enumerate over and over again in the XML.
  
  Please notify.
  
  Best,
  NAT

  If you already have the values in variables, why not just do that?

  select xmlroot(
   xmlelement
   (
    EMSData,
    XMLForest(
     v_DailyStartDate as "DailyStartDate",
     v_WeeklyStartDate as "WeeklyStartDate",
     v_MonthlyStartDate as "MonthlyStartDate"
    ),
    XMLAGG

• When no rows returned in the query loop, replace Null - need help

  Hello
  
  I have a requirement where I have a request in the loop for and based on the results of the query, I do some operations.
  
  But even if the query does not match, I should get back something like 'No Data'.
  
  My loop is:
  
  FOR V_SL IN)
  SELECT ID, CATEGORY, DI_CD, REV_CD, SL_ID
  OF SB, SLOT_2001 S2 SLOT_DATA WHERE
  PBM BENEFIT_ID = S2. BENEFIT_ID AND
  REV_CD = IN_REV_CD AND
  (PROC_CD IS NULL OR PROC_CD = IN_PROC_CD)
  ORDER OF DIAGCODE, PROCEDURECODE)
  LOOP
  END LOOP;
  
  I do some operations inside the loop for. I want the loop to run even if the query returns no rows.
  
  Can someone help me out here.
  
  Thank you
  Rambeau

  Frank. I am really surprised to see this coming from you. A slider to not find all the lines loop does not cause an exception no_data_found.

  As you can see there are two results and and two invoice lines.

  I want to create a table of invoice lines for which the line number is present in the result.

  So my psudo code is as follows

  for each in result:
       assign result.linenumber to variable
       for each in InvoiceLines:
            compare the InvoiceLines.Line_number to variable:
                 if match print row.
  

  I know I won't have access to the LineNumber result with in second forloop because of the determination of the lexical scope.

  Far from assignment, I am unable to get the value of the number of the line itself.

  I tried two methods of application for with in what work force. The underside of work that uses the absolute path.

  What xpath Miss. Can I do better?

  FOR1: <?for-each:/DATA_DS/Line_Approver/getLineNumberAssigneesResponse/result?>
  
  FOR2: <?for-each:/DATA_DS/DATA_DS/HEADER/INVOICELINES?>
  

  LINE_NUMBER	LINE_TYPE	AMOUNT
  For 1 <? LineNumber? > 2 LINE_NUMBER	LINE_TYPE	AMOUNT ENDFOR1 ENDFOR2

  I think I gave enough information. Answer just in case I did not say anything clearly.

  You can do this via a simple foreach loop and the code would be

  Please see the data XML and RTF attached for your reference.

  I changed the data in XML format (I added 10 instead of 1) just to make sure that its works or not, and it works very well.
