Shuttle point - example of packaged applications

• Shuttle point - save the changes

  The shuttle point integrated is a good way to view and edit data to multiple values. If the data comes from a single line and column (delimited), using the internal order process line Fetch and automatic DML to read/write, it work well.
  
  But what happens if the data from multiple lines in a source table? Say 10 lines are selected (right hand of shuttle) off a 50 LOV. The Source of the element of the shuttle has just the query to retrieve the 10 lines and the APEX engine automatically converts multiple values into 1 delimited value required by the shuttle.
  
  But when it comes to saving the changes in the shuttle, there is no easy way to identify what has changed. Say I deselect the option 1 and select 2 new items in the left side of the shuttle. Value of the element in the session state is delimited by colon 1 string containing the currently selected values. How this translates into the ELIMINATION of 1 and 2 INSERTs necessary against the base table?
  
  I can think of to save the front-subimit value in a hidden element, comparing it to the value of after-submit and stuff like that, but that seems a lot of work. What this kind of thing done effectively?
  
  Thank you

  As the table changed with the values of the shuttle contains one column other than the PK and the shuttle update column, this can all be handled with reusable one DML MERGE statement and a utility function:

  begin
  
    merge into shuttled_states ss
    using (
    /*
      The merge source requires a set of matched pairs: the selected shuttle values
      against the corresponding values in relevant DB rows, for example:
  
      shuttle_st  db_st
      ----------  -----
      X           X       -- X is in both shuttle selection and DB rowset
                  Y       -- Y is not in the shuttle selection but is in DB rowset
      Z                   -- Z is in the shuttle selection but not DB rowset
  
      We therefore need to leave the X row in the DB unchanged, delete the Y row,
      and insert the Z row.
  
      This query should also contain other columns and values required in matching
      rows in the merge, or in inserted rows.
    */
      select
          shuttle.column_value shuttle_st
        , db.st db_st
      from
          table(string_to_coll(:p37_states)) shuttle
            full outer join shuttled_states db
              on shuttle.column_value = db.st) t
    /*
      Match conditions normally include matching PK and/or other values to get the
      relevant DB rowset, but the main requirement here is a predicate that matches
      using the DB value column from the shuttle/DB rowset pair.
    */
    on (ss.st = t.db_st)
    when matched
    then
    /*
      This is where the restriction applies. Although we don't actually want to
      update any matched rows as they are unaffected by the shuttle selection, the
      MERGE can only delete rows that have been updated. However we can't update
      any of the columns used in the match, so there needs to be at least one
      column available that can be set to the same value to mark the row as
      updated...
    */
      update
      set
          ss.state_name = ss.state_name
    /*
      ...which makes it possible to delete rows that are not selected in the shuttle.
    */
      delete
      where
          t.shuttle_st is null
    /*
      Where there's no match the value is newly selected in the shuttle and is
      inserted as a new row.
  
      (Other values required should be included in the query, or handled in a
      trigger.)
    */
    when not matched
    then
      insert
        (st)
      values
        (t.shuttle_st);
  
  end;
  

  This method uses to transform the selected values shuttle of a string delimited by two points in a set of SQL. The function provided by Oracle apex_util.string_to_table returns a PL/SQL associative array that is not appropriate for this. If it is possible to convert a string into lines purely using SQL, these methods are rather obscure and only can be reused by cutting-and-pasting. A simple function that returns a collection of standard SQL type can be used as a set of rows in a query through the SQL TABLE operator and is highly reusable:

  create or replace function string_to_coll (p_string in VARCHAR2) return sys.ODCIVarchar2List
  is
  
    l_table apex_application_global.vc_arr2;
    l_list  sys.ODCIVarchar2List := new sys.ODCIVarchar2List();
  
  begin
  
    l_table := apex_util.string_to_table(p_string);
  
    l_list.extend(l_table.count());
  
    for i in 1..l_table.count()
    loop
      l_list(i) := l_table(i);
    end loop;
  
    return l_list;
  
  end;
  

  For purposes of demonstration, this one uses the predefined sys . ODCIVarchar2List collection type. In real life, you would create your own, and of course the function would be in a package, not stand-alone.

• Availability of packaged Applications Oracle Apex

  Nobody knows when the packaged Applications Oracle Apex will be available again to the page dedicated to the
  http://www.Oracle.com/technetwork/developer-tools/Apex/application-express/packaged-apps-090453.html says simply:
  "Previous applications packaged and code examples have been removed and new applications are being developed."
  
  I could really do with a copy of the application to the time sheet to use as a base, still an old version of it and not really care too much about all the bugs reported in it.
  If anyone knows where I can get a copy, I'd appreciate it.
  
  Why was it necessary to remove the old packaged Applications, why not let them available until new ones have been developed.

  Send your email address in texas. Apex. Developer @ gmail. com and I can send along a copy of the application to the timesheet...

• Save the shuttle point

  Hello

  I am trying to record the content of an element of the shuttle. I m using a "Save"-button that triggers a process (PL/SQL anonymous block). "."

  The content of the element of the shuttle should be stored in a table.

  The point of shuttle from filling with a calculation of work. Store new items that have been enjoy on the left side to the right side works just as well.

  Unfortunately I m not able to delete an existing element on the right side.

  If I remove an item from the right to the left and click on the button "Save", I get the error "ORA-01722: invalid number". "."

  I m using the following PL/SQL block:

  DECLARE
    v_count        NUMBER  := 0;
    v_shuttle_ids  VARCHAR2(1000);
    v_shuttle      APEX_APPLICATION_GLOBAL.VC_ARR2;
  BEGIN
    v_shuttle := APEX_UTIL.STRING_TO_TABLE(:P47_PFLANZLICHE_HERKUNFT);
  
    FOR i in 1 .. v_shuttle.count LOOP
      SELECT COUNT(*) INTO v_count FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id = v_shuttle(i);
  
      IF v_count = 0 THEN
        INSERT INTO rjm.material_objekte (objekte_id, material_id) VALUES (:P47_OBJEKTE_ID, v_shuttle(i));
      END IF;
  
      v_shuttle_ids := v_shuttle_ids || v_shuttle(i) || ',';
    END LOOP;
     
    v_shuttle_ids := SUBSTR(v_shuttle_ids, 0, LENGTH(v_shuttle_ids) - 1);
  
    DELETE FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id NOT IN (v_shuttle_ids);
  END;
  

  The Delete statement fails because the data types are not compatible. The variable v_shuttle_ids is the VARCHAR2 data type and the database column material_id has the NUMBER data type.

  Anyone has a solution to the problem (for example, casting data types) or has a better way to remove existing items from the shuttle point?

  Thank you in advance,

  Patrick

  If I understand the problem, your code should look like this:

  DECLARE
    v_count        NUMBER  := 0;
    v_shuttle_ids  NUMBER_TT;
    v_shuttle      APEX_APPLICATION_GLOBAL.VC_ARR2;
  BEGIN
    v_shuttle_ids := NUMBER_TT();
    v_shuttle := APEX_UTIL.STRING_TO_TABLE(:P47_PFLANZLICHE_HERKUNFT);
    FOR i IN 1 .. v_shuttle.count LOOP
      SELECT COUNT(*) INTO v_count FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id = v_shuttle(i);
      IF v_count = 0 THEN
        INSERT INTO rjm.material_objekte (objekte_id, material_id) VALUES (:P47_OBJEKTE_ID, v_shuttle(i));
      END IF;
      v_shuttle_ids.extend();
      v_shuttle_ids(v_shuttle_ids.last) := v_shuttle(i);
    END LOOP;
    DELETE FROM rjm.material_objekte WHERE objekte_id = :P47_OBJEKTE_ID AND material_id NOT IN (SELECT column_value FROM TABLE(v_shuttle_ids));
  END;
  

• Apex 4.2.2 lack a packaged application

  Hi all

  I've updated to 4.2.2 apex. and I was wondering if the previous announcement that asset manager packaged application would be included in this version has changed.  I have made a mistake in my upgrade,

  "Also I Googled it and I come back with several presentations on".
  What's new in 4.2.2"which include the Asset Manager.

  For example:

  www.Oracle.com/.../Developer.../apex/... /apex- 42-new-features-1867076...

  http://nyoug.org/presentations/2012/December/Sewtz_APEX_4-2.PDF
  This blog shows including a plenthora of apps I do not see under the packaged applications
  http://bkintsiful.blogspot.com/
  Thanks for an overview
  Ministry of education

  Hi Moe,

  APEX 4.2.2 is not an application packed - the application of the "Asset Manager" package was not scheduled for yet.  Although this application name packed received game slides of Marc, he has not yet been available.  Please note the slide in the sphere of security, slide 3, in this slide deck, which essentially provides that the information contained in the slide deck are not a commitment to deliver.

  All the packaged applications that are available in your case are listed under the tab "packaged Applications. During an upgrade process, any new application packaged will be added to this list.  You don't need to do all the extra steps during an upgrade.  But "Asset Manager" is not yet available, you may find it useful to examine the applications available, where you can find one that meets your requirements.

  I hope this helps.

  Kind regards

• Can you please give some advice on the ToolTip used in the new packaged applications

  Hello
  I use apex 4.1 theme 23.
  I would use the ToolTip used in the new packaged app.
  Can you please give some advice or the "Details" on ToolTip, used in the new packaged applications. for example: go live checklist request.
  Once we fly over "Check list items" region. We get the tootip.
  
  1. how to find the class "detailedStatusList".
  2. how to find "detailedStatusListToolTip();" JavaScript function used in "execute when Page Loads.
  3. is there a tool to generate the source in the region to "check list items.
  
  I don't know if there are more, I need to know...
  
  * the tooltip plugin isn't solid...
  
  Kind regards
  Water

  Good morning, water,

  My goal is to use it in IR for the column notes. I can't show all the notes on the report. so I use RPAD to show only the first words. and the rest should be available by using the ToolTip.

  Fact :D

  You need to use SUBSTR to restrict the notes to a few words, not RPAD.

• I changed the IR query as follows...

  select
  Deptno,
  Dname,
  Loc,
  substr(notes,1,25) || '<div class="long-notes" style="display:none;">'||notes||'
