• How the two function return values

  Dear all,

  Please explain, how the two values of function return?

  give a simple example.

  OK, a few examples...

  First example, using a type of structured on the database object:

  SQL > create or replace type tMyValues as an object (yr number, number, number of dy mn)
  2.

  Type of creation.

  SQL > create or replace function getMyValues return tMyValues is
  2 number of y: = extraction (year sysdate);
  number of 3 m: = extraction (sysdate months);
  number of 4 d: = extract (day of sysdate);
  5. start
  6 return new tMyValues(y,m,d);
  7 end;
  8.

  The function is created.

  SQL > set serverout on

  SQL > declare
  2 myValues tMyValues;
  3. start
  4 myValues: = getMyValues();
  5 dbms_output.put_line (' year: ' | myValues.yr);
  6 dbms_output.put_line (' month: ' | myValues.mn);
  7 dbms_output.put_line (' date: ' | myValues.dy);
  8 end;
  9.
  Year: 2015
  Month: 4
  Day: 1

  Second example, using an associative array within PL/SQL:

  SQL > set serverout on
  SQL > declare
  2 type tMyValues is table of the index number to varchar2 (10);
  3 myValues tMyValues;
  4
  5 function getMyValues return tMyValues is
  6 retValues tMyValues;
  7. start
  8 retValues ('Year'): = extraction (year sysdate);
  9 retValues ('Month'): = extraction (sysdate months);
  10 retValues ('Day'): = extract (day of sysdate);
  11 return retValues;
  12 end;
  13. begin
  14 myValues: = getMyValues();
  15 dbms_output.put_line (' year: ' | myValues ('Year'));
  16 dbms_output.put_line (' month: ' | myValues ('Month'));
  17 dbms_output.put_line (' date: ' | myValues ('Day'));
  18 end;
  19.

• ExtendScript function return values

  As far as I know, it is only possible to perform functions an Extension of CS ExtendScript. I see no (direct) to obtain the return value of a function of ExtendScript.

  CSXSInterface.getInstance () .evalScript () does not return any useful information. Am I missing something, or should I make a feature request?

  Substances

  Hey, substances,

  Try:

  function test1() {}

  Alert ("Hello");

  return "."

  }

  You must serialize the object into an Xml STRING to return, and it must be in the format above (for an object in the property data of the SyncRequestResult). You can't return an object directly. It will not automatically put in the above xml format.

  You can also send back an arbitrary block of XML.

• Calling a function multiple return values...

  Hello

  I wrote a simple function 2 return values. It comes to my own understanding.

  create or replace function func1 (empid number)

  Return number

  is

  number of SAL;

  number of deptID;

  Start

  Select the wage in sal of employees where employee_id = empid;

  Select department_id from deptid from employees where employee_id = empid;

  return of sal;

  deptid return;

  end;

  I tried to call the function like below: -.

  declare

  number of performance(1);

  Result2 number;

  Start

  performance(1): = func1 (101);

  Result2: = func2 (101);

  dbms_output.put_line(result ||) '' || Result2);

  end;

  output:-1700 1700

  the salary was posted twice.

  I understand that the second query has not been taken into account.

  Please let me know how this can be achieved.

• Function - return multiple values in a concatenated string

  Hello
  
  Is it possible for a function return a concatenated string (combining more than one number). I'm trying to return the purchase by the introduction and invoice_id number and code order number, but an invoice_id can have several PO with the same code number. I want to concatenate the PO numbers with commas, for example
  
  10124, 10090, 10987
  
  At the present time, the function returns NULL for those cases that have more than one purchase order number.
  
  Thank you

  func_get_po(i.invoice_id, cc.code_combination_id) "PO No",
  func_get_po_requester(i.invoice_id, cc.code_combination_id, func_get_po(i.invoice_id, cc.code_combination_id)) "PO Requester",
  

  Of course, this can be done without any problem.
  If it returns NULL, then you must debug function and check the operating logic. I know that it will take a little of your time, but not problems with the logic of syntax and concatenation.

• Use the return value to do step digital multiple success or failure

  Hello

  I use a multiple digital step to check several measurements by an external DMM through a function created in CVI.  I would like to use the return value of the function to replace the global status of the step. The reason is that the return value indicates a communication error, while steps are being taken, and which would lead to a "fake" fake or false 'Pass '.

  What I would do is more or less this >

  If the return value is 0, then check if the measuremets are between the limits

  If return value! 0 = there was a communication error so step continues to operate independently of the measure.

  I tried combining multiple digital step with a step of pass/fail, but it does not work.

  I also trie to change the expression of the status of the multiple digital steps but basically ignores him.

  Any ideas?

  Thank you

  Javier

  Why don't you just make that return the value limits for multiple numerical limit stage.  Comparison of the EQ value and the low limit to 0.

  That would make the most sense.

• Return value of DLL LabVIEW Build to the Prototype of the function

  Hi all

  I know LabVIEW can generate a DLL with return value with a function like prototype

  Sub nomfonction (arguments);

  We could define the return value to arguments.

  However, LabVIEW build a DLL with return value instead of "null" in the United States

  int nomfonction (arguments);

  In fact, I could achieve this when my part of connector VI has a 1 linked indicator.

  I could get my prototype of function dll in the application as Builder

  Double functioname (void); or well functioname (void); or some

  Although I could do above, this applies only when my VI has 1 single output.  If the VI

  1 more arguments, I still get

  Sub nomfonction (arguments);

  So I missed something? Or is this a limit of LabVIEW?

  Please don't get angry if this question has been asked before, I'm lack of subject

  LabVIEW to communicate with other languages.

  Thank you

  Jean Cyril

  You can.  In the construction specifications, under source files, go to set your prototype.  on the right, there is a drop down 'Output VI' which is what you want.  Note that I only saw him able to return numeric values.

• 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,.

  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).

• Problem of return values of functions

  Flash MX2004
  I am trying to create a game similar to Lingo, if you've never seen on TV. I had a bit of code that was working until I decided to divide it functions... specifically I try return values of 2 functions, and I get nothing back. When I track it comes back undefined. Can we have a look at this code to see if there is something really wrong with her?
  
  Any help is greatly appreciated!

  Rothrock, Craig,

  Thank you both for your help. I applied your suggestions and now my tracks are back with the results that I expect!
  Awesome!

  Now to continue to work on this stuff... it's an assignment for a class account tomorrow and I have a long way to go...

• ORA-06503: PL/SQL: function returned no value

  Hi guys,.
  I wrote a function that returns the number of quarter for a given date.
  Here's the function
  
  FUNCTION to CREATE or REPLACE fn_get_quarter
  (p_date DATE)
  RETURN NUMBER
  AS
  v_qtr NUMBER;
  BEGIN
  Select TO_CHAR (p_date, 'Q')
  IN v_qtr
  DOUBLE;
  dbms_output.put_line (' it's quarter ' | v_qtr);
  END;
  
  It compiled without error.
  
  Here is the test case that I wrote
  
  DECLARE
  p_date DATE: = TO_DATE('12/22/2009','MM/DD/YYYY');
  v_qtr NUMBER;
  BEGIN
  v_qtr: = fn_get_quarter (p_date);

• Impossible to retrieve the return value of function from pl/sql using the DB adapter

  Dear Experts,
  
  I use the DB adapter in my BPEL process. Using the DB adapter I invoke a PL / SQL function. I am able to send two input parameters for the pl/sql function. But I do not know how to retrieve the return value of the function. Please suggest me.
  
  Thank you
  Rajesh

  Can you tell how pl/sql function looks like you? you return the value of the function, right?

• Offshoot of page based on the return value of function

  I have a combo box (P2008_SUPPORTING_MATERIALS) with 'Yes' and 'No' values.
  
  I need a button that will save the selected value, and then create a branch to the 1092 page if it of 'Yes' or branch to page 2094 if it is 'no '.
  
  That's what I did:
  
  1 create a SAVE button
  2. created a page process of type PL/SQL with function (see code below) inside (PageBranchDecision). The conditional processing I put him "when press button" for the "SAVE" button.
  3. create a branch of the page with a branch type of DIRECTION to the FUNCTION RETURN A PAGE. For the action of the branch, I put the name of the procedure on the page (PageBranchDecision). Because these are conditions, I defined him "when press button" on the "SAVE" button.
  
  This is the code for the page process:
  
  DECLARE
  whole n_page_id;
  v_sup VARCHAR2 (3);
  
  BEGIN
  v_sup: =: P2008_SUPPORTING_MATERIALS;
  
  IF v_sup = "Yes".
  THEN
  SELECT 1092 INTO double n_page_id;
  RETURN n_page_id;
  ON THE OTHER
  SELECT 2049 INTO double n_page_id;
  RETURN n_page_id;
  END if;
  
  END;
  
  Now, that's the problem... According to the 'Oracle HTML DB manual"page 294 books and ' easy Oracle HTML-DB' page 307, with the type of the branch of 'Branch to function returning a Page', a function PL/SQL is written which returns a digital page at junction id. In my code, it would be 'n_page_id '. But, when I run my page and click on my "SAVE" button I gives me an error that a RETURN statement cannot contain an expression.
  
  I don't know why I get this error. I need to get the value of the page to the branch based on the 'yes' or 'no '.
  
  Someone has an idea what I am doing wrong? My situation seems, as it is possible through the logic, I'm following?
  
  Thanks in advance,
  Maggie

  ch - ensure that any unconditional branch on the page has a largest number in sequence to ensure that this branch is triggered and ensure that there is no other branch that is triggered by the "SAVE" button

• StartAsyncTask using and obtaining a return value

  Hello

  I'm just starting to try and learn LUA and all Lightroom SDK.  Here is a sample of my code:

  local lrApplication = import "LrApplication".

  local LrTasks = import "LrTasks".

  local activeCatalog = lrApplication.activeCatalog)

  local currentPhotos = activeCatalog:getMultipleSelectedOrAllPhotos()

  are there local = LrTasks.startAsyncTask (function () return currentPhotos [1]: getFormattedMetadata ('fileName') end)

  wheneven check or try to use y sucks.

  Please someone tell me the stupid thing, I am doing wrong so I lose more hair decrease.

  I know that currentPhotos has 5 photos in its collections, because later I do this:

  because me, I onePhoto in ipairs (currentPhotos)

  and he travels 5 times, matches to the top for the number of photos in the folder I selected in Lightroom.

  Thank you.

  Start-async-task does not return a value, it just schedules a task and keeps going on - the job runs later.

  In general, it is best to start a task immediately in response to a menu button or press selection... and everything in this task. -then you don't need to start anywhere, unless you need it like real parallel processes, such as background tasks.

  To avoid multiple tasks from due to asynchronous events, use a form any to avoid recursion.
