• reload the page when SQL query returns a value

  Hello world

  the title of this discussion may seem strange, but I'll try to explain why I need this:

  A user has the ability to connect on my APEX application. There are several tabs in my application that are visible only if a certain SQL statement returns a value which is not the case by default. The user has also the ability to download a file that is transferred to an external system that analyzes the file and writes the data in the database. During this writing process - which may take several minutes - conditions for some of the tabs to show the will becomes real (-> the query will return a value). When the user refreshes the page manually, the tabs will be displayed. However, I want the tabs will appear automatically when the condition is met.

  Is it possible to refresh the page as soon as the query returns a value? It is perhaps possible to check it on the client side and trigger a refresh of the page when the condition is met. It would be even better if only the tabset has been updated, but refreshing the full page is fine as well.

  Thank you!

  Here is an overview of how it can be done

  This is possible thanks to a dynamic action being performed on a timer.

  View default tabs and dynamic action hide them on loading the page if they are not to be considered

  Create a dynamic action that will execute your query every 5 seconds or more

  If the query returns data, you can use the dynamic action to show your tabs using javascript

• Guest user does not return a value

  I have a user prompt dialog box which is a slightly modified version of questioning the standard user to enter VI express. I tried to change the VI so that it would allow the user to close the command prompt by pressing the enter/return key. The final objective is to have the popup dialog, the user will scan a bar code and barcode reader adds a carriage return, automatic closing of the dialog box character.

  I have followed this user lyrics: https://decibel.ni.com/content/docs/DOC-13973. The only difference between my code and the code it is that my user dialog box returns a string instead of a number. See below for my code.

  

  

  The problem that I am running is the string "Item number2" never really returns any value once it's called. The indicator on the front panel of the updated the express vi displays the correct value after you run, but the value is never returned to the VI, who called the dialog box. The express vi the value default value is successfully returned. The only change I made was the addition of the structure of the event, so I have to assume that my code does not go inside this node.

  Any thoughts are appreciated.

  Adjust the chain drive on 'Update value then of the hit'.

  

• Line tool command that returns a value

  Is it possible to compile a VI to work as a tool of command line that accepts arguments and returns a value? I need to create commands that will be run from a shell script and return values that will be used in the script in order to evaluate the results. If possible, the type and the range of values can be returned? I've seen a few posts on the masking of the façade, but none on the return a value to the shell of the appellant.

  Andrey,

  Thanks for your help. The only thing missing from your response to me was that I use c#. In this case, you simply have to add code to manage a DLL unmanaged like this:

  using System.Runtime.InteropServices;

  public class Win32

  {

  [DllImport ("Drive Letter: \\path to dll\\DLL Name.Dll")]

  public static extern double Testing();

  }

  After you have added this code to import the DLL in a class of your choice, you can call the function to run the LabVIEW VI library.

• bbUI.js and localStorage.getItem return null values

  Hello

  I build a WebWorks app with bbUI.js for BB10 and I run problems when I want to retrieve items of localStorage. Their storage is no problem. Here is my architecture:

  1. index.html which uses localStorage.getItem in a function ondomready for 1 screen (fueltracker.html), it works
  2. JS/Register.js with functions like registerUser(), registerEngine(), registerBrand(), registerModel() called when onclick in their respective screens, see below
  3. RegisterUser() calls register.html
  4. registerBrand() calls addCar.html
  5. registerModel() calls addModel.html
  6. registerEngine() calls addEngine.html
  7. fueltracker.html which has a few buttons that the label should be changed to values from localStorage

  The register() functions make a call to localStorage.setItem (), working (i.e. the values are defined). However, in some cases parts of objects stored in localStorage it update, so this object must be recovered first, updated and then stored again. Unfortunately the calls localStorage.getItem () does not return the value that is stored in the localStorage.

  So how does it do?

  Yes Chad, variables have been established.

  It's the same problem as this one: http://stackoverflow.com/questions/2010892/storing-objects-in-html5-localstorage (objects cannot be stored in LocalStorage, single key-value pairs, so items must be chained before putting them in the LocalStorage). The getObject() en index.html setObject methods and their use instead of getItem() and setItem() solved the problem.

• Function return undefined values

  My function returns undefined values. It seems that the return of the function statement is executed before the database is queried and values are assigned to variables. If I do an alert within the loop for () I get the correct values from the database, but these values are not affected before excecuting the return statement function. How can I do this differently?

  function getColumnNames(table){
      var rs1, rs2, rs3, rs4, rs5;
      db.transaction(function (tx) {
          tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
              var size = results.rows.length, i;
              var item;
              for (i = 0; i < size; i++){
                  item = results.rows.item(i);
                  rs1 = item.col1;
                  rs2 = item.col2;
                  rs3 = item.col3;
                  rs4 = item.col4;
                  rs5 = item.col5;
                                  alert(rs1); //correct value is returned here
              }
          });
      });
      return [rs1, rs2, rs3, rs4, rs5];
  }
  

  Hey Fabian,.

  You are quite correct that the return statement is executed before the database returns the results. There are ongoing asynchronous calls. You can set breakpoints in JavaScript code to see what is happening. You can correct the problem by using function callbacks. I edited your code below to use the callback functions - there might be a few typos, but the general approach should be wooded.

  function getColumnNames(table, callback){
      var rs1, rs2, rs3, rs4, rs5;
      db.transaction(function (tx) {
          tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
              var size = results.rows.length, i;
              var item;
              for (i = 0; i < size; i++){
                  item = results.rows.item(i);
                  rs1 = item.col1;
                  rs2 = item.col2;
                  rs3 = item.col3;
                  rs4 = item.col4;
                  rs5 = item.col5;
                      alert(rs5); //correct values are being returned
                  callback([rs1, rs2, rs3, rs4, rs5]);
              }
          });
      });
  }
  
  // example of how to call getColumnNames with callback
  getColumnNames('importantTable', function (result)
  {
      console.log(result);
  });
  
  // alternative version
  function onCallback(result)
  {
      console.log(result);
  }
  
  getColumnNames('importantTable', onCallback);
  

  I hope this helps.

  See you soon,.

• COS() returning incorrect values

  Hi, anyone of you tried get values of cos() to native c++... ? It seems that sin values are correct, but the cos returns incorrect values. As for example, sin(pi/2) Returns infinity. No idea what could be wrong?

  @SuhairZain,

  #include 
  #include 
  int main(void)
  {
          float pi = 3.14159265f;
          printf("Result: %f\n", sin(pi/2));
  }
  

  Result: 1.000000

• Do stuff to PL/SQl that returns the value and redirect to modal page by setting this value

  Hello

  a button click Page1 I would perform a PL/SQL procedure that returns a value in P1_ITEMVAL and then redirect to a page 2 (modal page) and the value of an item on this page with the value previously returned. To do the same thing with a normal page is quite easy:

  Button action is present, then process of PL/SQL that returns the value in the P1_ITEMVAL element and, finally, a branch at page 2 that sets P2_ITEMVAL with P1_ITEMVAL. I really have no idea how to do the same thing when the target is a modal page.

  I created a unit test on https://apex.oracle.com/pls/apex (application 1554 - redir_to_modal)

  Workspace: tests

  USER: supporter

  PWD: supporter1234

  Any help would be much appreciated.

  If you prepare a URL using the value calculated in the PLSQL of DA part you can then use a subsequent stage of javascript to set the location of the window.

  This will jump to the top of the page of the modal dialog box

  : P1_URL: = apex_util.prepare_url)

  ' f ? p ='|| : APP_ID - Application id

  |': 2' - Page id

  ||': ' || : APP_SESSION - Session id

  ||':'                      -- Request

  ||':NO'                    -- Debug

  : ': ' - Clear Cache

  : ': ' - Settings

  ||' P2_ITEMVAL'

  : ': ' - Parameter values

  || (: P1_ITEMVAL);

  then in the action of javascript

  Window.Location.Replace ($v ('P1_URL'));

  Hope this is of some use

• Cannot return a value in LOV

  Dear all,

  I have create a LOV in my code field that is a primary key at my table. And I can't return the value from the lov,

  I get the below error.

  oracle.jbo.InvalidOperException: Houston-29114 ADFContext is not configured to process this exception messages. Use the code of exception stack trace and error to investigate the root cause of this exception. Root cause error code is Houston-34014. Error messages settings are {0 = oracle.jbo.Key [null A9], 1 = root}

  Please note that am I 1 primary key with 2 field in my table.

  And note that use jdev 12.1.3

  Another solution...!

  There is always another solution:

  -' they' can remain on Oracle Forms and forget ADF

  -' they' can refine their requirements to equip the technical constraints of the ADF

  -' they' can use some other technologies instead of the ADF

• What subprogramme should we prefer to return multiple values with OUT parameter?

  Hello

  I worked on the procedures and functions, and aware of their differences. Today I have an interview question that - suppose I don't have return multiple values through a subroutine and I want nor run any what DML within this subprogramme and I want to use this subprogramme in the SQL query. What subprogramme I would prefer - "Operating Mode" or "Function" and why?

  In my view, both can be used in this case, but want to see your views and opinions.

  Kind regards

  Sachin jerbi

  In terms of software engineering, if you claim something that you expect to "return" something (a value or values) then you use a function.  If you call something to "do" something, and then you use a procedure.

  THE settings are not good practices in many cases and should not strictly considered "return" of values.  Instead, they are assigned values in the code and generally act as pointers to the original variable/structure that was passed as a parameter (the actual internals of Oracle don't quite do it, but in principle this is what they do).

  A return value (or structure) of a function is basically push in the battery to the point that the RETURN statement is issued, and then the code calling the stack appears to assign it to a variable or placeholder, it should go in.

  If it seems a little difference between procedures and functions to some people, it is recommended to use functions for obtaining values and procedures to do things, in most cases.  It is not just "syntactic sugar", as mentioned above.

• Plugin to point that returns multiple values

  When you create an APEX element that can return multiple values, such as a checkbox, APEX uses the settings of varchar2 p_v01 - p_v200 instead of the p_t01 table settings - p_t200.

  I would like to create a plugin item type that can return multiple values in the same way, so that the session recorded for the item state contains a delimited string of values.  I realize, I could achieve with Javascript and a hidden item, but I really want to a non-Javascript solution.  Is this possible?  If this isn't the case, it would be a nice improvement!

  Hi Tony,.

  Take a look at the level of the parameter p_is_multi_value of the APEX_PLUGIN. GET_INPUT_NAME_FOR_PAGE_ITEM api (http://docs.oracle.com/cd/E37097_01/doc.42/e35127/apex_plugin.htm#AEAPI1254). If you set it to TRUE, you will get one of the p_v01 - p_v200 table settings. It's the same what our box element type calls.

• Returns the value of column line

  Greetings!  I currently have a request we will tell

  SELECT value, period FROM MAS_CFUS_KEYACM_CONTROLDATA ORDER BY cf_keyword_ID

  RESULTS

  Period value

  --------------------------

  100.0002 1 JANUARY 14

  -35.68 1 DECEMBER 14

  -1943.67 NOVEMBER 1, 14

  678.0013 OCTOBER 1, 14

  This continues for about 15 results by cf_keyword_ID.

  I'm looking to return the VALUE first in a new column called PREV1, the second value of PREV2, third in PREV3 and so on.  The same goes for the dates.  And all this for only the first 10 values of each cf_keyword_ID.  Can anyone suggest the best way to achieve this?

  Thank you!!

  Hello

  This is called pivoting.  Because I don't have a copy of your table test, I'll use scott.emp to illustrate.

  This shows the first 3 employees for each job, in order by hiredate, along with their hiredates:

  WITH relevant_data AS

  (

  SELECT ename, job, hiredate

  row_number () taken OVER (PARTITION OF work

  ORDER BY hiredate

  ) AS r_num

  FROM scott.emp

  )

  SELECT *.

  OF relevant_data

  PIVOT (MIN (ename) AS ename

  MIN (hiredate) AS hiredate

  FOR r_num (1, 2, 3)

  )

  ORDER BY job

  Re: 4. How can I convert rows to columns?

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  Explain, using specific examples, how you get these results from these data.

  If yod post rather a problem using scott.emp, then you need not display the sample data; just results and explanations.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  Back AFTER using the exception block is fine as long as your code actually REACHED the exception block.

  When there are no errors, then your code will not enter the exception block, but you still NEED to return a value, since it is what functions a function wants to return a value, that's what the functions are made for.

  Spot the differences between the following 3 functions. Understand how they work.

  The first function has only a return in the exception block but runs correctly. Result: error, because the back is missing in the code block.

  The second function has a return in the exception block and one in the block of code and runs correctly. Result: no error, because the return is not missing in the code block.

  The third function has a return in the exception block and one in the block of code and is forced into an error. Result: no error, because the return of the exception handler is used (instead of retriggering of the error, which you would normally do).

• Is there a way to get v ('APP_USER') to return a value in sql developer?

  Hi all

  I had a vision that looked like this:

  I discovered that to replace the call to sys_context (as below) made my request 10 times faster.

  select *
