• LOV and return value

  Hello

  I have a lov and the return value of this lov is assigned to a formval. I have a Viewobject VO1 which is attributed to the return values of point LOV. After selecting a value from the lov, I am tring to get the return value later of the viewobject Vo1 but he still presents as null.

  Don't know how to get the return value. Any help is appreciated.

  Thank you

  KK

  KK,

  That's what I understood.

  You have a LOV which has 2 lovMaps, it returns the field of LOV and 2 returns the value for the FormValue field.

  The formValue field is mapped to an attribute of the VO.

  After you select the value from the LOV, you try to get the value returned to the FormValue using the VO attribute attached to the value of the shape.

  How are you trying to access the value and where?

  See you soon

• How to do a function with the same argument multiple times and return values in the variables?

  The problem I have is that I have created a function that is really kind of database.  Basically, a bunch of:

  If (a.value == 'number') {}

  b.value = "this expression."

  }

  Inside of the shape are 2 drop-down lists that return numeric values I want to process through this function and the value of return inside separate variables.

  var a = this.getField ("OPE003. EVEN.1.MIP");

  MIP (a);

  var Result1 = Mip();

  I tried to smash * a * to treat the second field

  a = this.getField ("OPE003. EVEN.2.MIP");

  MIP (a);

  var Result2 = Mip();

  Result1 and result2 are placed in an array, joined as a string.

  In doing so, I always get the last treatment twice more than the final result.

  Can I use a function as a batch processor that way?

  You're right, I changed the code to what you said, but how to pass another value by my function so I can get Result1 and Result2?

  is it

  var a = this.getField ("OPE003. EVEN.1.MIP");

  var b = this.getField ("OPE003. EVEN.2.MIP");

  Result1 var = Mip (a);

  var Result2 = Mip (b);

  var c = new Array [performance(1), result2]

• display and return value to the selection list.

  Ooh, NEGATIVE... Can you not use a NOT EXISTS in this case, could have a significant impact on the execution plan?

  Something like this maybe?

  SELECT f_name||' '||l_name,
         stundent_id
  FROM class_record a,
       s_per_det b
  WHERE a.student_id = b.student_id
  AND   a.class_id   = :P1_CLASS_ID
  AND   a.section    = :P1_SECTION
  AND   NOT EXISTS(SELECT 'X'
                   FROM student_type_details c
                   WHERE a.student_id = c.student_id
                   AND   c.class_id = :P1_CLASS_ID
                   AND   c.section = :P1_SECTION)

• How to send the SQL for SQL Server statement and return data without using database connectivity Kit?

  Hi, I tried to figure out how to extract data from my SQL Server databases and reading messages and to do some tests with examples, I can get data connection type in my SQL server, but so far nothing helps.  Is it possible to get data from a SQL Server database without using the database connectivity Toolkit?  and if so, how?  are there whitepapers and/or examples of this?  So far, I can't find something that works.  Thank you.

  Jesse - what is your reason for not using the database connectivity Toolkit? It is by far the best way to recover the data.

• The procedure for anonymous block PL SQL Exception Handling problem?

  Hello

  I am a newbie to PL/SQL.

  I'm having trouble when trying to manage exceptions for block anonymous PLSQL procedure I created will format any block of 10 digits and format it in the next (XXX) - XXX - XXXX.

  I need.

  1. the handle if there is more than 10 digits

  2. the handle if there are less than 10 numbers

  3. the handle if there is no inappropriate character (no number)

  4. the handle if there is no characters.

  I created the following procedure.  However, my if/else attempts logic or raise exceptions have create errors so far.

  Please enter the following code.

  create or replace

  PROCEDURE format_phone

  (

  p_phne_no IN OUT VARCHAR2

  ) IS

  extra_digits EXCEPTION; -Number must be a 10-digit number. Please enter the 10-digit

  no_digits EXCEPTION; -Please enter numbers there is no registration numbers.

  invalid_char EXCEPTION; -You entered a wrong character please enter numbers 0-9.

  less_digits EXCEPTION; -You have entered too few figures. Please enter a 10-digit phone number.

  BEGIN

  p_phne_no: ='(')

  || SUBSTR (p_phne_no, 1, 3).

  ')'

  ||' -'||

  SUBSTR (p_phne_no, 4, 3)

  ||' -'||

  SUBSTR(p_phne_no,7);

  -DBMS_OUTPUT. Put_line (p_phne_no);

  EXCEPTION

  WHEN invalid_char

  THEN

  dbms_output.put_line ('you have entered an inappropriate character please enter 0-9 numeric values.');

  WHEN no_digits

  THEN

  dbms_output.put_line (' Please enter the numbers there is no registration numbers.) ") ;

  WHEN less_digits

  THEN

  dbms_output.put_line (' you entered too few figures.) Please enter a 10-digit phone number. ") ;

  WHEN extra_digits

  THEN

  dbms_output.put_line (' you entered too many numbers.) Must include a 10-digit number. Please enter the 10 digits. ") ;

  END format_phone;

  Thank you for your concern.

  >>

  OK so I need to declare a variable, then pass p_phne_no parameter to this variable.

  You could, Yes, but you don't need to. You could simply test the value of the passed parameter

  Length (p_phne_no) > 10...

  > - I need 3 scenarios more in which I test Val., which is always equal to the parameter p_phne_no?

  Yes (or just test p_phne_no).

• C++ call and return value

  hand. QML

  app.importGraph (selectedFile);

  I call a C++ function to get a file in the system

  c ++

  void ApplicationUI::importGraph (QString fileName) {}

  QString newGraph;

  bunch of code that adds the contents of the file to newGraph

  Here, I want to newGraph back to what ever QML did importGraph C++ function call, how is this done?

  }

  Hello

  This can be done simply return from the function:

  QString ApplicationUI::importGraph(QString fileName) {
    ...
    return newGraph;
  }
  

  In QML:

  var myString = app.importGraph(selectedFile)
  

  importGraph must be reported as Q_INVOKABLE and "app" saved as contextProperty.

  A property may be used to track the changes. We must define a getter, setter and a signal. There are some sample code in the section "Object C++ exposing to QML" on this page:

• Global exception handler

  Hello guys,.

  I'm trying to implement a handler for global exception (https://blogs.oracle.com/jdevotnharvest/entry/extending_the_adf_controller_exception_handler) by extending oracle.adf.view.rich.context.ExceptionHandler class and put the fully qualified name of the class that is implemented in the file .adf/META-INF/services/oracle.adf.view.rich.context.ExceptionHandler.txt .

  I see that it works locally jDeveloper (Studio Edition Version 11.1.1.6.0) when the built-in but server deployment does not work when it is deployed to the server of a dev... I see the folder has been created in the tmp folder in dev server and the file is there, not sure what else to try. Please help.

  Thank you

  Aerts

  OK finally solved! It was with the declaration of .adf/META-INF/services record - it seemed when the exception handler server deployment was not get registered. To debug the registered services, you must use the following.

  
            ServiceLoader compilers = ServiceLoader.load(ExceptionHandler.class);
              _logger.info(compilers.toString());
  
              for (ExceptionHandler compiler : compilers) {
                  _logger.info("******ExceptionHandler*********" + compiler);
              }
  

  If you check the loggers, the exception handler should be listed, otherwise then create a jar file with the class of exception handler and to put the issue of services along - with the file of exception handler (not a text file) within the META-INF of the jar file. Last step - put the jar file in WEB-INF/lib in your controller project.

• on exception handling in function, while using this function in sql

  Hi gurus,
  
  I have a question concerning the registration of exceptions when using functions.
  
  I wrote a separate package to handle errors, where I have a procedure.
  In this process, I connect my error in a table and then triggers the error on the front end.
  Ex:

  proc_log_and_raise    -- this proc... inserts my error into a table and then raise

  now, I have included this error procedure in all functions and procedures.
  
  Consider an example with an example of procedure and function.

  function func_1(( v_var   varchar2) return varchar2 is
  begin
       select   column2
       from     table2
      where col1 = v_var;
  exception 
      when others then 
           proc_log_and_raise;
  end;   

  procedure proc_1( v_var   varchar2) is
  begin
      select   func_1(v_var)  -- error occurs here..
      from     table_a
      where   col1 = v_var;
  exception 
      when others then 
           proc_log_and_raise;
  end;    

  now I do

  exec  proc_1( v_var );

  but now my problem is, when an error occurs in func_1, I get an error with the DML operation (as we are inserted in the table of errors)
  ORA-14551: cannot perform a DML operation within a query.
  
  So what I want to do, connect the two functions and procedure where the error occurred.
  
  So is it better otherwise, we can write our exception handling, so that I could mistake the newspaper and use the function in a select statement.
  
  Thank you.

• the return value of tpacall(), tpcall and tpgetrply()

  The return value of tpacall() weather, tpcall and tpgetrply() has a rule? I found that the return value of them is an integer that has increased by one. What is its maximum value? Or it will be a loop in a scope? Thx for your answer!

  Bill,

  A return of tpacall(), tpcall() or tpgetrply() of-1 indicates failure. Any other return value indicates success.

  Unless the TPNOREPLY indicator is used, the value returned by tpacall() is a handle that can then be passed to tpgetrply(). (The alternative is to call tpgetrply() with the TPGETANY flag, in which case the handle returned by tpacall() will be necessary.) When using the indicator TPNOREPLY tpacall(), tpacall() returns 0 success. In both cases, the only error return value of tpacall() is - 1.

  The return value on the success of tpgetrply() is not documented (except that it is not - 1), but it seems to be the descriptor of appeal on which a message was received, which is the same information that you can place in * cd.

  The return value on the success of tpcall() is not documented (except that it is not - 1), but currently, the value 0 is generally returned on success.

  Kind regards

• LOV query is not valid, a display and a return value is necessary, column n

  Hello
  
  I AM FACING
  

  LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, 
  the first FROM clause in the SQL statement must not belong to the in-line query.

  with two table, I create lov
  
  the tables are
  

  CREATE TABLE  "CRM_SALES_DEPARTMENT" 
     (     "DEPT_ID" NUMBER NOT NULL ENABLE, 
       "CUSTOMER_ID" NUMBER NOT NULL ENABLE, 
       "DEPT_CODE" VARCHAR2(50) NOT NULL ENABLE, 
        CONSTRAINT "CRM_SALES_DEPARTMENT_PK" PRIMARY KEY ("DEPT_ID") ENABLE
     )

  CREATE TABLE  "CRM_SALES_CUSTOMERS" 
     (     "ID" NUMBER, 
       "CUSTOMER_NAME" VARCHAR2(255), 
       "CUSTOMER_ADDRESS1" VARCHAR2(255), 
        PRIMARY KEY ("ID") ENABLE
     )

  I USE QUARY
  

  select (SELECT CS.CUSTOMER_NAME FROM CRM_SALES_CUSTOMERS CS WHERE CS.ID=SD.CUSTOMER_ID) AD D, SD.CUSTOMER_ID R  
  from CRM_SALES_DEPARTMENT SD where SD.DEPT_CODE=:P16_MARKET 

  But who show me LOV query is not valid, a display and a return value is needed, the column names must be
  different. If your query contains a query online, the first CLAUSE in the SQL statement must not belong to the query online.
  
  How to solve this problem.

  Select (SELECTION of CS. CLIENT_NAME CS CRM_SALES_CUSTOMERS WHERE CS.ID = SD. CUSTOMER_ID) AD D, SD. CUSTOMER_ID R
  CRM_SALES_DEPARTMENT SD where SD DEPT_CODE =: P16_MARKET

• Dynamics of stocks & value (Exception thrown and not caught cascading list

• Handling SQL exceptions

  Hello

  I have a problem to understand how to manage the SQL Exceptions when using JdbcService in LiveCycle ephemeral process.

  Could you guide me to an article on handling sql exceptions?

  I see, that many services a 'bolt' in its visual representation (for example the Document FileUtilsService/Write) and it is possible to define alternative workflows by dragging the new road of bolt.

  What is the standard way to handle the sqlException exception then?

  Thank you.

  The latest version of LiveCycle contains a 'bolt' to catch exceptions.

  If you use 8.2, you can try to take advantage of the Exception event.

  Create a separate process and add an Exception start Point event. It must catch the exception.

• Compare multiple columns and return a different value

  I have more access to excel and I'm running my previous workflow in numbers of duplication of issues.

  I have a worksheet when a sheet with all my power tools.  On the "Power Tools" sheet I have columns for the brand, Type, model, purchase date, etc...  An example of this would be: pass a "DEWALT", "Jackhammer" Col B, Col C "DCD995M2" and so on.

  I have a second sheet in the same document which is my front end if you want.  I wanted to have selections for this dynamic drop-down list but it seems it is not possible without scripts, but is not the immediate question yet I'm the mention the case where someone knows a good fix.  The second sheet "Sorting Test", I created manually drop-down boxes, one in column A of the brand and the other in column B for Type.  I'll choose the brand and type and I want numbers autofill the rest of this line based on these two selections.

  Example:

  In the 'Sort Test' sheet I select DEWALT in column A and I select the drill in column B and I want DCD995M2 is displayed in column C and the purchase date in column D and so on.

  Excel in it would be a game table or something similar.  So far every site and search google only gave a lot of people who try to do VLOOKUP or correspond to errors, but I've really met anyone corresponding to two distinct cells from two separate columns and return data from this same line a match was found on.

  I must also mention I'm really trying to avoid adding a hidden line that combines some of these but I know it's the most noticeable work around.

  Basically, I want to match two selections separated against two separate columns, and when it finds the match, I want it returns a different value of this corresponding line how I got everything just copy this formula on adjacent cells and simply adjust to the column in the same row matched.

  I know that I shouldn't do this on separate sheets, but it's just a choice that I made a point of design.

  Any help would be appreciated, because I'm trying to really get the most out of the numbers, especially with how it syncs between desktop and mobile and I have more access to Excel.

  You can it as what you do and why?  This will help us understand what drives the design.  Leave out how to solve the problem,

  also post screenshots can be very useful

• How to execute a Perl script and returns the value as a string?

  Hi, I am trying to build an application using the eclipse 2.0.0 with the Blackberry SDK 7.1 plug-in. currently I tested Simulator 9900 version 7.1.0.523. I need to use the Perl language to access the raw biological database and returns as a string without having to write a longer program using java.

  In a stand alone Java SDK, I can use the line:

  Process p = Runtime.getRuntime () .exec ("perl script.pl")

  but when I tried to use it on the IDE for a Blackberry project, the project will not compile. It is said:

  Method exec (String) is undefined for the type of Runtime

  Hopes, can someone show me the correct syntex to use, but if no class is available, could someone show me a sample for unified research process? The names of blackberry dev is very complicated, I can't find any samples for her.

  Thank you.

  Seems interesting.

  Your idea was to download the data to the BlackBerry and then directly execute queries.

  Although there are a number of other obstacles, the first fall you in East platforms supporting Perl.  Here is the list:

  http://perldoc.Perl.org/perlport.html#supported-platforms

  BlackBerry OS Java is not included - in fact the only ' included phone OS is Symbian.  Interestingly, it seems likely that PlayBook and BB10, because they are based on the QNX operating system.

  If we discard Perl as a query language, then you will need to provide another option to search.  I think that unified search is an option, but you will have some work to do to use it.  The first thing you should do is find out if in fact, you can download the database on the BlackBerry.  The only available on the Blackberry database engine's SQL, so if you want the database can be exported to a SQL database, there is a chance that it would work.  I had a quick glance around the site, and I can't tell what the "database" is in the format.  Then I suggest that look you at that next.

  I hope this helps.
