Cascading list of values & query

• Problem creating list of values query

  Hi all

  I am facing some problem with a simple list of Apex selection list item values query which is:

  RETURN 'select distinct dd_type as d, dd_type as r
  from portal_02.WAVE_'||:P86_WAVE_ID||' @ DATABASE_LINK1 
  order by 1';
  

  And I get this error during the execution of the page:

  ORA-06550: line 2, column 99: PL/SQL: ORA-00942: there is no ORA-00942 table or view: table or view is no ORA-02063: preceding the line of DATABASE_LINK1 ORA-06550: line 1, column 13: PL/SQL: SQL statement ignored ORA-00942: table or view is no ORA-02063: preceding the line of DATABASE_LINK1

  
  

  I placed also p86_wave_id cascading of parent elements.
  

  Anyone has an idea why this is happening and how can I fix this problem?

  Use: Apex 4.2.6 & Database 11g.

  Concerning

  Nabila

  I was wrong.

  You are positive that a value exists in the session state for P86_WAVE_ID? For your first attempt, one might think it was empty when loading the page, when he made everything that uses the list?

  Ahh, there you get this when you try to save the definition of LOV, it is probably just trying to validate the request, made with a null value.

  Not sure if you can get it to analyze at run time, but you could workaround with a wave_ object definition?

• Join the query in a dynamic list of values query

  I have a join query in a dynamic list of values query. The value does not return a value of text, but rather the value of the ID.
  
  Is it possible to use a join query in a dynamic list of values query?
  
  For example... in the query below, I expect to see ename in the drop-down list, but I see class_emp_id.
  
  Select b.ename d, a.class_emp_id r
  of class_emp a, b of the emp
  where a.class_cat_id =: CURR_CLASS_CAT_ID
  and a.emp_id = b.emp_id
  order by 1
  
  Thank you
  Reid

  Hey Reid,

  The structure of the pairings/value of the item is incorrect - it should be: item1, item2, etc.: value1, value2, etc, so:

  ' f ? p = & APP_ID.: 50: & SESSION. ": P50_LP_ID, P50_LP_NAME, CURR_CLASS_CAT_ID: #LP_ID #, #LP_NAME #, #CLASS_CAT_ID #"

  I guess that CURR_CLASS_CAT_ID does not use the prefix P50_?

• Cascading list of values with a many-to-many relationship

  Hi all

  I have three paintings; semester, subject and half of subject. Each semester has a lot of topics and a subject can be taught in several semesters.

  create table semester(
       id number not null,
       name varchar2(50) not null,
       primary key(id)
  );
  create table subject(
       id number not null,
       name varchar2(50) not not null,
       primary key(id)
  );
  create table semester_subject(
       id number not null,
       semester_id number not null,
       subject_id number not null,
       primary key(id),
       foreign key(semester_id) references semester(id),
       foreign key(subject_id) references subject(id),
       constraint semester_subject_uq unique(semester_id, subject_id)
  );
  
  

  EDIT: I have a page with a report that shows all students who are currently enrolled in the selected for the selected session object.

  There are two selection lists at the top of the report, one for the half and the other for the subject.

  What I try to do is when you select a semester in the half selection list, the topic selection list should contain only the subjects for the half of some (not all) in the subject of the painting.

  h

  If the relationship was of 1 to many that I could write to see half of value

  select name, id
  from semester
  order by 1
  
  

  and for the purpose of value list

  select name, id
  from subject
  where semester_id = :PX_SEMESTER
  
  

  But now that the relationship depends on the table of semester_subject, I can't find a way to achieve this and Googling has not helped.

  Thanks in advance for any help.

  I believe that this issue has also been implemented on stack overflow plsql - list of values cascading with many-to-many relationship - stack overflow and received a very wide response. If the OP has not yet verified, he may want to.

  You do not want a list separated by commas. You want to move a collection. Then

  CREATE TYPE num_tbl
  AS
  TABLE OF NUMBER;
  
  DECLARE
    l_list_of_ids num_tbl := num_tbl( 10, 20, 30 );
  BEGIN

  When generating dynamic SQL statements, it is always advisable to connect the instructions generated before you run the diagnostics/debugging. Change the body of the LOV function to:

  declare
    l_lov_sql varchar2(4000);
  begin
    l_lov_sql := 'select nvl('||:P13_STUFE_2||',job) d,nvl('||:P13_STUFE_2||',job) r from emp WHERE deptno=nvl('''||:P13_STUFE_1||''',deptno)';
    apex_debug.message('P13_STUFE_2 SQL: ' || l_lov_sql);
    return l_lov_sql;
  end;
  

  That said, the problem seems to be positioning the NVLs. When P13_STUFE_2 has no value, then the generated statement clearly causes a missing expression error:

  select nvl(,job) d,nvl(,job) r from emp WHERE deptno=nvl('',dept no)

  When P13_STUFE_2 is set to null, a valid column name must appear in the generated LOV query:

  l_lov_sql := 'select ' || nvl(:P13_STUFE_2, 'job') || ' d, ' || nvl(:P13_STUFE_2, 'job') || ' r from emp WHERE deptno=nvl(:P13_STUFE_1, deptno)';

  You must also check/clean up the value of P13_STUFE_2 to avoid the risk of alteration of the value leading to code SQL injection.

• Cannot change PopUp LOV width and height in version 4.2.5.00.08. I change the values of 450 400 in the Popup list template values (Section of the window), but my function genList0_f07_$ _row (), retains the same settings. Is this a bug?

  Hello

  I use APEX 4.2.5.00.08 to my app.

  I have a region of reports, where I display a column set. A column is the column attribute "display as" the value 'Popup LOV (LOV based query).

  I press the button to retrieve the LOV, I get a popup of 450 x 400 pixels.

  I go to the side of the model and navigate to "Popup list of values of model", where I can see in the section 'Window' attributes 'Width' and 'Height' value 450 and 400. I edit them and save them and there is nothing going on. I'm sure that the template belongs to my selected theme.

  I saw in the HTML source code that is the called function:

  <!--

  
  function genList0_f07_$ _row)

  I see that the values has not changed. I also connected and disconnected. I am inclined to believe that it is a bug of the APEX.

  The only solution I think is to replace this function, which is NOT ideal.

  Thank you

  Digital

  The parameters are generated only, nothing you can do about it because it does not use the model for these properties of the couple. Other things work fine for example the names of button or title window etc. I guess that, Yes, it is a bug. It's still there in the apex 5 too, I checked. The default values of the template do not match, the value in the generated code is always 400/450. So I guess it's pretty much a wait on 5.1.

  Here's a fun hack to make it work well on your page (works in apex 5 too, because the code is always the same). Put this in the execute on loading of the page section:

  (function(){
    var _open = window.open;
    window.open = function(){
      if ( arguments[1] === "winLov" ) {
        arguments[2] = "Scrollbars=1,resizable=1,width=500,height=700";
      };
      return _open.apply(window, arguments);
    };
  })();
  

  Change the settings to your liking. This will replace the existing window.open call, which is what the popup lov use and replace it with our own code. It does not interfere with other things. As the name of the new window is always "winLov" for the popup lov, it is the argument that is checked.

  During the call to window.open to open a new window with the name "winLov", parameters are replaced with your own version of it. The window is called as usual, using the stored reference.

  Edit:

  Yes, do not use the trick of resizing. My hack can be a bit tedious, but it's much less invasive for the end user (see open, bam, resize. "Even gets funky on multiple monitors). Also, this thing in the popup lov template will affect each lov popup that you use in the application, which is much less interesting than my specific page code.

  Edit2:

  I did a little digging in the source code, and I don't know why it does not work. Popup lovs are actually equipped to deal with it. My guess is that the parameters are recovered only after that the lists were generated, causing the package variables global to use their default values instead of model parameters.

• List of values of VO

  There are two options

  Option 1:

  2. create a unique VO based on 6 entities created

  3. with the creation of the original Version, there is an option to specify the type of join between entities

  Option 2:

  Create a VO based on query here, you can write your own custom with all necessary gaskets query

  Create a view of criteria adding the required fields.

  Map the VO as a LOV for the required field

  Run the view criteria prior to the loading of the page.

• How to add 'show all' to a list of values

  I have a page element (P10_AIRCARRIER), which is a list of selection - and the list of values is a standard query:
  
  Select faa_name display_value, faa_code return_value
  table
  
  The report based on the selected in the select list, faa_name is filled.
  
  It works fine, however the client would like to add 'Show all' to the list of values in the select list, so that if this field is selected, the region of report presents data for all air carriers instead of one.
  
  Can you please indicate how I would do that, as Im not able to add the value "show all" at the table.
  
  Im running 4 Apex.
  
  Thank you
  Laura

  Change the query to:

  select faa_name display_value, faa_code return_value
  from table
  union all
  select '- Select All -', null
  from dual
  order by 1
  

  Assuming that faa_name values sort after "- select -", it will be the first entry in the list. (Changes should be fairly obvious to other requirements...)

  In the report query, the following expression correspond to a certain faa_code, or if "- select all -" is selected:

  ...
  faa_code_column = coalesce(:p10_aircarrier, faa_code_column)
  ...
  

  (Use to_number(:p10_aircarrier) if the faa_code_column type is NUMBER.)
