LOV and return value

• LOV, not return values more some limit

  Hi guys,.
  
  I created 2 fields of research (State, region) in report page. Two of them are based LOVs. The user select the first value in the field, the next field LOV return values based on the first field (AJAX call). First field is States as "VIC", "NSW", "HIS" etc., next field is 'Space'. When I select State other than "NSW" in the State field and then the next field is filled with success. But when I select the State as 'NSW' then the next field is empty. "NSW" State has made more than 100 in the table (LOV based on), but other States have even less than 10 records. When I remove "NSW" (more than 50) documents in the table then it works.
  
  Can - as anyone knows if there is a limit of LOV that can be taken in charge?

  Bill:

  The presence of special characters is exactly what I had suspected.

  You must use the function replace in the query that is run by the "application process" that is called by your AJAX call. This process of applicition generates the XML code, which is then used by your Javascript to build the LOV.

• 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.

  How can I do that.
  
  
  Thank you

  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)

• PL/SQL exception handling and return values

  Hi all
  
  I use Oracle 10.2.0
  
  I have a problem in the return values of the procedures if there is no exception.
  
  For example:
  
  

  procedure a.
  (
  P_in number,
  p_out on varhar2
  )
  as
  p_valid varchar2 (10);
  number of p_no1;
  Select 1 in double p_no1;
  B (p_valid, p_no);
  exception when others then
  c (errmsg);
  end;
  put an end to;

  procedure B
  (
  p_in number,
  p_valid out varchar2
  )
  as
  fake number;
  Select 1 in double dummy;
  dummy cases = 1
  then
  p_valid = "OK".
  C (MSG);
  end;
  exception when others then
  p_valid = "OK".
  C (errmsg);
  end;
  
  end b;

  In the example if theres no exceptions or dummy = 1 in procedure B, then I need to return the value as 'OK' in the setting out of the parent procedure "A".
  
  I could not this value, returning null. How to get this...
  
  Please advice...

  Ok

  The code you have posted is not valid code if you have forgotten some important things. However, we will make it simple...

  If you have a set OUT that will not be filled if an exception is thrown, unless it is set to NOCOPY.

  Example of...

  Here, we regularly parameter output and when an exception occurs in procedure B it REVIVAL of the exception to the procedure a...

  ORA-06512: at line 1
  

  Obviously, when the procedure B raised an exception it went directly to the procedure exceptions A manager that indicates that an exception has happened and the value returned in the OUT parameter was NULL.

  Now, if procedure B just handles the exception rather than erect in...

  SQL> ed
  Wrote file afiedt.buf
  
    1  create or replace procedure B (p_in in number, p_valid out varchar2) as
    2    dummy number;

    5    p_valid := 'OK';
    6  exception when others then
    7    p_valid := 'EXCEPTION';
    8* end b;
  SQL> /
  
  Procedure created.

  Returned without exception: OK
  
  PL/SQL procedure successfully completed.
  
  SQL> exec a(2);
  Returned without exception: EXCEPTION
  
  PL/SQL procedure successfully completed.
  

  Here, procedure B fills the output parameter and just returns execution to the block to execute procedure A, so A procedure isn't aware of no exception, but the output parameter does not contain the value B populated with.

  But if you want the procedure B to throw the exception and pass out a value in the output parameter, you must set the out parameter as NOCOPY...

  SQL> ed
  Wrote file afiedt.buf
  
    1  create or replace procedure B (p_in in number, p_valid out NOCOPY varchar2) as
    2    dummy number;
    3  begin
    4    select 1 into dummy from dual where p_in = 1;
    5    p_valid := 'OK';
    6  exception when others then
    7    p_valid := 'EXCEPTION';
    8    raise;
    9* end b;
  SQL> /
  
  Procedure created.
  
  SQL> exec a(1);

  ORA-06512: at "SCOTT.A", line 8

  Now, as in the first example, procedure B defines the output parameter and throws the exception, causing execution to go directly to the procedure A exception handler, but this time, A procedure return parameter value out.

• 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:

• copy the select value in the textfield of LOV, and allow the user to modify

  Hello
  I have a datablock with 20 records and each record has a comment (say field_comments) fields. I would like to allow the user to choose LOV populated predefined comments (say lov_comments) and add a few additional comments after they choose the value of LOV.
  
  I created a LOV and added the return type 'field_comments' in column mapping properties. When the user clicks a button, LOV opens. They choose the value of the LOV and the value goes to the field 'field_comment '. The problem with this approach, the user cannot add their comments after selecting in LOV.
  
  I tried this too much. I created another area of non-visible text (i.e. fake). In the LOV, I added "dummy" field as returntype. In the dummy field, I created the trigger 'After the CHANGE', which basically says: block. field_comments =: block. Mannequin.
  
  But, the user must click another field to display the value selected from the LOV. The values of the 'field_comments' is not being updated as soon as the user click on the 'OK' button in the LOV.
  
  I'd appreciate if someone could give me feedback and help to solve my problem. Thank you for your help.
  
  I thank.

  Well, I tried exactly what you posted and it allowed me to SELECT from LOV, then CHANGE/ADD new text in front of returned value in the field. He recorded in the database and questioned without any problem.

  Your article is allowed to INSERT/update? If this isn't the case, then set yes "Update/Insert allowed" and attach your LOV to the element and set "post to list" No.

  You can also see if you have any validation done on WHEN-VALIDATE-ITEM trigger or after CHANGE which will fail because you change LOV populated values.

  I hope that helps!

• Lov return value in a variable to library package (PLL)

  Hello world!
  
  I use a kind of generic/dynamic LOV for multiple forms (referenced LOV and custom in a library (PLL) functions.
  
  Is anyway to set a LOV to return a value into a variable package library?
  When I try, I get the error "+ name of the FRM-11908 element must be valid and exists in the form. +"When you click on the '+' column mapping LOV...
  
  I also tried to use the global variable... I can put my LOV to return value to a global variable... but I can not access in the library package... I get an error: "+ error 49 bad bind variable... blah blah blah... met the OVERALL symbol while waits for blah blah blah... +»
  
  
  Did anyone of you knows how to work around these errors and get my LOV returns values returned in a package variable or access a global variable in a package?

• Same display and return in a LOV value

  Hello
  
  I have a project referenced by change_name name.
  
  I have the table using the values of change_name, now in the shape I want to display the value of change_name can be in a shuttle or the list manager.
  
  The problem, I can not display and return the same value of a LOV.
  
  The code is :-d Select distinct (change_name), separate (change_name) r QLM_project
  
  This code gives me an error message indicating that the display value and the return value has different verses.
  
  Thank you
  Rakesh

  Hi Rakesh,

  It is perfectly possible to have the same performance and display the value in a LOV.
  The problem here is your query; It is syntactically incorrect.

  Try this query:

  select distinct change_name d, change_name r from qlm_project  
  

  Good luck

• 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.
  
  Thank you

• How to return a NULL value in LOV and insert into a field of allowingNULL number 4?

  Hello
  
  I have the following LOV and the return_value is PeopleId which is number 4, allowing NULL. And the LOV options are as follows:
  
  LOV named--> select named LOV-
  Show Extra values-> no
  Dynamic translation-> - untranslated-
  The number of columns - > 1
  Display Null-> Yes
  Null-> - Select value-
  Return NULL,-> NULL value
  ^^^^^^^^^^^^^^^
  
  ----------------
  
  List of values definition:
  Select Lname | ', ' || Fname | ' ' || Mname as display_value, PeopleId as return_value
  of PEOPLETB
  where PEOPLETYPE ('i', 'HERE', 'IF')
  order by 1
  --------------
  
  Given that PoepleId is a number 4, allowing NULL. I want a NULL value will be inserted, if the user does not select anything in the drop-down list. It seems that I would get "ORA-01722: invalid number" error when the PeopleId msg is null (ie: user doesn't have a selection). What is the good 'return Null value' I need to put it in? I tried "NULL" (see above) or nothing, it still does not work.
  
  Any suggestions?
  
  Thank you very much
  Helen

  Hello Helen,.

  You have found one of the many sources of my frustration with APEX. Here's what I do:

  In the definition of the element in your page, go to the LOV part and implemented like this:

  Display Extra values: Yes a dynamic conversion (I ignore this)
  Number of columns: 1 display Null: No.
  Display null value: (leave blank) return Null value: (leave blank)

  An empty row is displayed when the user comes first to the screen. If they do NOT select the drop-down list, the value is left empty (null).

  If anyone has a better way, I will definitely experiment with it.

  If it comes to a page element, and then change the type of Popup LOV key.

  If there is a control in a table, it's another reason to upgrade to a supported version, or the tabular form will need to be converted to be manually generated and processed in order to allow the appropriate control be returned using the apex_item.popupkey_from_lov method

  Not really sure what you are after. You can try this.

  {

  String lovInputSourceId = pageContext.getParameter (SOURCE_PARAM);

  If ("".equals (lovInputSourceId))

  {

  }

  I don't want to argue, but your column of the MyLOVCount table contains the string "null", which is not equal to null.

  You not fill it but the fact is that there is the mystery.

  Your condition <... or="" mylovcount="" like="" '%null'||'%';="">is looking for the word "null".

  Please see the screenshots below; line with col1 = 'b' meeting condition tran_type is null and col1 = 'a' tran_type meeting = 'null '.
