• Mathematical functions with input/output error

  Please refer to the attached picture. Where do you find these mathematical functions with input/output error? I saw these in response to a message.

  I think they appear when you connect a waveform or dynamic data type.  Since I rarely use these data types (just give the table!), I'm not positive.

• Mathematical functions in C99

  Hello everyone once again.

  I try to use the mathematical functions from C99: nearbyint, round, exp2, cbrt, etc... But they do not appear to be defined in the CVI2013 header file.

  I previously would compile the (with gcc) only if __STDC_HOSTED__ has been defined, but it seems that, even if she does not appear in the predefined options listed in the build options, this macro is now defined in CVI2013...

  So if CVI is now compatible with C99, where are the features? And if not, how do I know if they are present or not, below #ifdef _CVI_?

  Note the test seems to be:

  #if _XOPEN_SOURCE > = 600 | _ISOC99_SOURCE | _POSIX_C_SOURCE > = 200112L

  C99 present mathematical functions

  #endif

• Mathematical function to show only the positive numbers?

  Does anyone know of a mathematical function to show only the positive numbers. I have a formula that returns an integer, if the integer is negative, I want to show ZERO. I'd rather not have to use a case statement.
  
  For example, if it returns 5, I want to see 5. If it returns 0, I want to see 0. If it returns-2, I want to see 0.

  How about this?

  (x + ABS) / 2

  where x is the column?

  When x = 5, you have (5 + 5) / 2 = 5

  When x = 0, you have (0 + 0) / 2 = 0

  When x =-2, you have (-2 + 2) / 2 = 0

• Mathematical function FRS

  I use the mathematical function in FRS 'PercentOfTotal([A,40],[A,39]) '. I chose to use a custom formula. But when I try to save him. He does not receive SACE and when I run web preview so I am getting error in each cell of this row.
  
  can someone help me with this. I don't know how these mathematical function work in FRS.
  
  Actally I want to perform ([A, 40] / [A, 39]) * 100
  
  Thank you

  When you select a cell/row/column formula, you should see the formula bar activate (go from gray to white) it looks like in the formula bar in Excel. There just above the POV. Either by the way, I want to talk about studio HFR, not the HTML client in the workspace. You should see (from left to right) a drop down menu where you can select different functions, then a help "?" then a red X, then a green check mark. After typing in your formula, click the green check mark to validate and "lock" function. Save your report and try to run it.

• Mathematical functions on db TinyInt columns does not work?

  I have several columns with integers stored using the SQL TINYINT data type. I am trying to add the columns and pass the average of Coldfusion:

  and #avgrating # guard display text without running the mathematical function as such:

  Look at the Pattern.vi ramp in the range of Signal Processing.  Also check the Board of ideas.  I think that someone posted an idea here about adding an option to the standard for loop step.

• By using the impl class for functions on a table

  I'm looking for a bit of advice on best practices.

  I have an app with 35 paintings.  I need to have a button "reset comes out" on each table.

  Each resetSort method should specify the table and the specific iterator.

  I tried to not having all the functions of 35 in the bean to support (1 for each table).

  Can I bind each table has associated feature class impl and each resetSort button call a method in this class?

  I use jdev 11.1.1.6.

  Any advice would be appreciated.

  Ray

  Then your real mission is to find the table for which the use wants to put sorting by pressing a button?

  This should be doable with the bean and a function that you bind to each of the reset buttons that you use for your tables.

  If your presentation is for the tables and the button to reset sorting, you can use an actionListener to the button. In the event of action, with the knowledge of the layout, it is easy to get to the table and once you have the table that you get the iterator from the table.

  Assuming that your tables are always surrounded by a panelCollection, who owns a toolbar now your reset button

  emptyText = "#{bindings." EmployeesView.viewable? "{'No data to display.': 'Access Denied.'}".

  fetchSize = "#{bindings." EmployeesView.rangeSize}' rowBandingInterval = '0 '.

  selectedRowKeys = ' #{bindings. " EmployeesView.collectionModel.selectedRow}.

  selectionListener = "#{bindings." RowSelection EmployeesView.collectionModel.makeCurrent}"="single"id ="t1">

  You can use this code actionListener

  {} public void resetSort (ActionEvent actionEvent)

  get the link container

  BindingContainer links is BindingContext.getCurrent () .getCurrentBindingsEntry ();.

  DCBindingContainer dcBindings = (DCBindingContainer) links;

  UIComponent toolbar (UIComponent) = actionEvent.getSource ();

  Try to get the source of the event table

  assuming that the button is in a toolbar of a panelCollection we get using parent.parent.children

  List of children of = toolbar.getParent () .getParent () .getChildren ();

  Table richeTableau = null;

  for (UIComponent uic: children) {}

  If (uic instanceof richeTableau) {}

  table = uic (richeTableau);

  break;

  }

  }

  If (table! = null) {}

  the model in the Collection is the object that provides the

  structured data

  for the table to render

  CollectionModel tableModel = (CollectionModel) table.getValue ();

  the purpose of the ADF that implements the CollectionModel is

  JUCtrlHierBinding. It is surrounded by the CollectionModel API

  JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding) tableModel.getWrappedData ();

  Acess the ADF, which is used with iterator

  ADF table binding

  DCIteratorBinding iterBind = adfTableBinding.getDCIteratorBinding ();

  table.queueEvent (new SortEvent (table, new ArrayList()));

  CurrentRow key = null;

  Line = iterBind.getCurrentRow ();

  If (line! = null)

  currentRow = row.getKey ();

  SC SortCriteria [] = new SortCriteria [0];

  iterBind.applySortCriteria (sc); iterBind is that the table iterator use

  iterBind.executeQuery ();

  If (currentRow! = null)

  iterBind.setCurrentRowWithKey (currentRow.toStringFormat (true));

  }

  }

  This code looks for the table of the source of the action, which is the button in the toolbar, get the tabel. Once you have the table you get the iterator from the table and reset the sort. This works as long as we find the source of the action table. If you always use the same layout for tables (for example. panelCollection > table), which is a practice of good uix, you have need of a bean to reset all tables. Simply link the toolbar button actionListner to the listener in the bean.

• First function (continued) 2 Tables

  I want to separate ID with a CODE and/or SER and first year 2010 or higher
  
  NB_3 table contains all the IDS that have codes SER
  NB_2 table contains all the IDS that have the CODE and YEAR
  
  It is or I am trying to achieve.
  
  Thanks to Shankar Viji
  I have the first year is greater than or equal to 2010
  who is

  SELECT *
    FROM (SELECT ID, YEAR, ROW_NUMBER () OVER (PARTITION BY ID ORDER BY YEAR)
                                                                             rn
            FROM dan_nb)
   WHERE YEAR >= 2010 AND rn = 1;

  Also, I would like to get the count instead of the ID
  something like

  SELECT *
    FROM (SELECT COUNT(DISTINCT(ID)), ROW_NUMBER () OVER (PARTITION BY ID ORDER BY YEAR)
                                                                             rn
            FROM dan_nb)
   WHERE YEAR >= 2010 AND rn = 1;

  But I get an error.
  
  Thank you
  Here are the 2 tables below.
  
  SELECT *.
  
  CREATE TABLE DAN_NB_2
  (ID VARCHAR2 (2))
  , YEAR VARCHAR2 (4)
  CODE VARCHAR (4))
  
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (1, '2009', '1');
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (1, '2010', '2');
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (1, '2011', '2');
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (2, '2011', '4');
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (2, '2012', '4');
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (3, "2006", 'Z');
  INSERT INTO DAN_NB_2 (ID, YEAR, CODE) VALUES (3, '2012', 'Z');
  
  
  
  CREATE TABLE DAN_NB_3
  (ID VARCHAR2 (2))
  SER VARCHAR2 (4))
  
  
  INSERT INTO DAN_NB_3 (ID, SER) VALUES (2, '37');
  INSERT INTO DAN_NB_3 (ID, SER) VALUES (3, '52');

  Two solutions:

  1. If you prefer analytical functions on the simple aggregate functions: you can get the same result by using various analytical functions: Rank, Dense_rank, Row_number, count etc.

  select count(distinct a.id)
    FROM (
            select a.id, first_value(to_number(a.year)) over (partition by a.id order by a.year) fv
              from dan_nb_2 a join dan_nb_3 b
                on a.id = b.id
         )a
   where a.fv >= 2010;
  

  2. If you prefer simplicity, using aggregate functions:

  select count(distinct a.id)
    from dan_nb_2 a join dan_nb_3 b
      on a.id = b.id
   group by a.id
   having min(to_number(a.year)) >= 2010;
  

  Moreover, why you store Date as Date instead of the data type VARCHAR2, keeps the character of number conversion?

• Download blob function instead of table field

  Hello
  Is it possible to download the content of blob field that are returned by a function?
  I can only download blob if the blob is in the column of the table...
  
  Thank you
  
  Vincent

  Hi Vincent,.

  I think you can download the blob content returned by a function with no problems. In the example below, the get_blob function returns a BLOB, you must specify the name and the mime type and the length of the BLOB is obtained using DBMS_LOB. GETLENGTH. Finally, a call to the wpg_docload.download_file procedure is made. To call the procedure download_file, you can do it through the URL or on a page with a 'branch at PL/SQL procedure' in the point "before Header". More info on this kind of procedure here.

  create or replace PROCEDURE  "DOWNLOAD_FILE"
  (
      inID NUMBER
  )
  AS
      vMIME VARCHAR2(48);
      vLENGTH NUMBER;
      vFILENAME VARCHAR2(2000);
      vBLOB BLOB;
  BEGIN
      vMIME := 'application/octet-stream';
      vFILENAME := 'Test.sql';
      vBLOB := get_blob(inID);
      vLENGTH := DBMS_LOB.GETLENGTH(vBLOB);
      owa_util.mime_header(nvl(vMIME, 'application/octet'), FALSE);
      htp.p('Content-length: ' || vLENGTH);
      htp.p('Content-Disposition: attachment; filename="' || SUBSTR(vFILENAME, INSTR(vFILENAME, '/') + 1) || '"');
      owa_util.http_header_close;
      wpg_docload.download_file(vBLOB);
  END;
  

  Kind regards

• Support of the functions of the table...

  Hello:
  
  Developer SQL supported SQL as below with the table of functions that return nested tables...
  
  Select * from TABLE (CSSGLOBAL. EMPDIV('454424'))
  
  I get error ORA-00902 invalid data type
  
  I'm on the Sql Developer 1.5.3
  
  Thanks - Yesh

  Try:

  select *
    from TABLE(CAST CSSGLOBAL.EMPDIV('454424') AS my_table_type)
  

  Where my_table_type is the user-defined type of table as CSSGLOBAL. EMPDIV returns.
  If CSSGLOBAL. EMPDIV returns a PL/SQL table type that is not defined for the database with code like:

  CREATE TYPE my_row_type AS OBJECT (my_col1 VARCHAR2(30), my_col2 NUMBER(10,0) ...);
  CREATE TYPE my_table_type AS TABLE OF my_row_type;
  

  then you have to re - write this way - SQL does not include PL/SQL tables.

• Problem with the function 'length' for table column in a table (fn)

  Hello
  
  I have a piece of javascript code that sets all the values of a column in a table:
  
  function exemptAll (flag)
  {
  Alert (document.wwv_flow. F42. Length);
  for (var i = 0; i < document.wwv_flow.f42.length; i ++)
  {
  var curr_id = document.wwv_flow.f42user.user;
  If (flag == 'Y')
  {
  document.getElementById ("curr_id") .value = "Y";
  }
  on the other
  {
  document.getElementById (curr_id) .value = 'n';
  }
  }
  }
  
  
  It works very well to provide in the form of tables, there are multiple lines, if only one line is the "document.wwv_flow.f42.length" function returns false values - we had '2' and '3' returned to a form of the tab that contains a single row and subsequently code fails with an error "invalid argument".
  
  Is this a recognized bug because we cannot find similar reports of what is happening on the forums. Any help would be appreciated as we have to fake a work around using an element of the page containing the number of lines in the tabular presentation.

  Hello

  I think that "bug" is caused by the dynamic nature of Javascript.

  If there is more than one field called f42, any reference to it will return an array of fields. However, if there is only one instance of it, any reference to it will return the field itself! In the latter case, probably the length function returns the number of characters in the field.

  Therefore, you must check whether what you have is an array or not. Unfortunately, there is no such function only as "isArray" in JS! If you are looking on the net for "isArray" you will find a number of alternatives well...

  I hope this helps.

• String function tab delimiter table worksheet

  Hi all, I am trying to use chain of worksheet to the array function to read on several lines of text and separate them in a 2D array. I have trouble using the delimiter. The default delimiter is tab, if I leave he unwired or use the Constant tab, it works, but if I use \t, it does not work. I'm using Labview 2013 and Windows 7 64-bit.

  Anyone know what is happening? Also, if I want to use several delimiters, what should I do?

  Thank you!

  Right-click on your constant tab, select "code view"... you might find a surprise:

  

  "you don't need to manually insert a tab because the function is set by default to it already, since you have... you'll find a back double return '."

• Call library function node, large table DLL by the way

  Hello

  I interfaced with success in most of the functions in a DLL, but it's trouble...

  Statement of header file:
  CORRTABLE * pDestCorrectionTable;

• Help for writing a mathematical function

  Hello again,

  I work on a tile game and need to understand an equation... I have a 12 x 11 grid... When I place a tile, I need to check for the existence of other tiles on the same row and column and sum their values...

  I need to create an equation with the following variables: -.

  Gets a number between 1 and 132: -.

  divides or multiplies the number in all the possible divisions of 12 between 1 and 132

  Adds or subtracts the correct amount of tiles that are either dependent on its position

  (I stretched the grid and, for example, tile 66 has five tiles on each side, tile 121 a 11 to it is because it is in the lower left corner)

  Hope this makes some sense to someone... I am now starting work on it, but any help would be appreciated!
