• How to use createRowSetIterator with 3 level master-detail?

  Hi experts,

  
  I use Jdev 12.1.3 and I need to iterate over objects in view of the AM lines (I have 3 level master-detail).

  With this code, I had access to the VO parent and create an iterator:

  ViewObjectImpl viewObject = getParentVO();  
  RowSetIterator rsIterator = viewObject.createRowSetIterator(null);  
  rsIterator.reset();  
  while (rsIterator.hasNext()) {  
     Row row = rsIterator.next();  
     // DO what do you want in Row  
  }  
  rsIterator.closeRowSetIterator(); 
  

  .. .but I don't know how to create iterators according to the parent of the child

  Any idea?

  Best regards
  Jose.

  OK, suppose that a relationship of master-detail Department and employees of the HR db schema. The link to the view that defines the master detail between the tables looks like

  

  The name of the accessor is EmployeesView. In the t generate line interfaces, including the accessors

  

  Make the avlailable of the accessor to the VO clinet interface

  

  and now you can iterate the children lines as

  private static ADFLogger _logger is ADFLogger.createADFLogger (DepartmentsViewImpl.class);.

  public void dummyTest() {}

  get the first line of the departmetns

  Line first = this.first ();

  DepartmentsViewRow depRow = (DepartmentsViewRow);

  lines children handler for employees

  RowIterator empView = depRow.getEmployeesView ();

  iterate over employees of the Prime Ministry

  Line row2 = empView.first ();

  While (row2! = null) {}

  do something with line 2

  _logger.info ("Emp:" + row2.getAttribute (0));

  row2 = empView.next ();

  }

  }

  This method is implemented in the DepartmentsViewImpl class.

• Validation of tabular form regarding the item master detail

  Hi guys,.
  
  I have installation master detail on my page with a layout table below.
  
  The master record has a field called RCV_QTY.
  
  The tabular presentation has a column called box_qty.
  
  What I'm trying to do is to validate it against the user to add lines in the table form which when added, is more than the amount of heading RCV_QTY.
  
  I tried the following function returns the validation text error but it's not enough work.
  
  As the line in the custom of tabular form be seen by the following SELECT INTO statements on submit, I guess I need more of a process of dynamic action type?
  
  
  DECLARE
  
  v_hdr NUMBER;
  v_line NUMBER;
  
  BEGIN
  
  SELECT hdr.rcv_qty
  IN v_hdr
  OF XXMEL_VMI_RCV_HDR_TMP hdr
  WHERE the hdr. VMI_RCV_HEADER_ID =: P2_VMI_RCV_HEADER_ID;
  
  SELECT SUM (line. BOX_QTY)
  IN v_line
  OF XXMEL_VMI_RCV_HDR_TMP hdr
  Online XXMEL_VMI_RCV_LINE_TMP
  WHERE the hdr. VMI_RCV_HEADER_ID = line. VMI_RCV_HEADER_ID
  AND hdr. VMI_RCV_HEADER_ID =: P2_VMI_RCV_HEADER_ID;
  
  
  IF (NVL(v_line,0) - NVL(v_hdr,0)) < 0
  THEN
  RETURN (' ERROR: the sum of the quantities of tag is greater than the quantity of the received header ');
  ON THE OTHER
  RETURNS A NULL VALUE.
  END IF;
  
  END;
  
  Any help would be great.
  
  I use Apex V4.0.

  Hello

  You must use the API APEX_APPLICATION total up to the Box_Qty of detail in Validation, and compare with the RCV_QTY. something like

  DECLARE
    V_BOX_TOT NUMBER := 0;
  BEGIN
    FOR I IN 1..APEX_APPLICATION.G_F01.COUNT LOOP
       V_BOX_TOT := V_BOX_TOT + TO_NUMBER( NVL(APEX_APPLICATION.G_F01(I),'0'));
   END LOOP;
   IF V_BOX_TOT > :P1_RCV_QTY THEN
      RETURN FALSE;
   ELSE
     RETURN TRUE;
   END IF;
  EXCEPTION
    .....
  END;

• Relationship need master / detail to post a link Master column to the different retail pass 2

  I have a form with a relationship master detail. The main block is a rec_shipments of table of database with a primary key of the shipment_id and a bunch of other columns. The retail block is a rec_containers table with a container_id as the primary key most column shipment_id, split_shipment_id, weight, volume, etc. The shipment_id and the split_shipment_id are nullable.
  
  When a shipment is received a shipping record is created and container records are created with the populous shipment_id and the split_shipment_id null. Under the shape of what a relationship is created between the block of the expedition and the block container as shipment_id = shipment_id. It works very well. However, they have the ability to spit the original containers in small containers easier to manage for the distribution. For example, if they receive a railroad car full of pallets of printer paper they can take and divide the, 1 tray of rolloff half-and-half into another tray of mitigation. The bins of rolloff will get a unique container_id for follow-up. Registration in the system created in the rec_containers table will be the populous split_shipment_id and the shipment_id null. On the screen, they want to see the (railroad car) original containers and containers of split (ferries rolloff) when the query expedition.
  
  What they want:
  Shipment_id - and additional information
  ID drive to railway and additional information
  Rolloff Bin 1 ID and additional information
  Rolloff Bin 2 ID and additional information
  
  My problem is the attenuation of bins do not arise with the current relationship because the shipment_id is set to null in the 2 files of bin rolloff.
  
  I tried to create a view on the rec_containers table that is all columns in the table plus 1 additional column which is
  NVL (shipment_id, split_shipment_id) comp_ship_id
  
  then assign the relationship shipment_id = comp_shipment_id. I have the comp_shipment_id column value query Yes and insert & update or not because I don't want to not update this column in the view.
  
  The problem is I can't update all the columns, I get a cannot book record to update or delete the error.
  
  Does anyone have any ideas how I can get the block of containers to query all records where the shipment_id or the split_shipment_id is shipping block shipment_id and still be able to update the records?
  
  Thanks for any help.

  Your idea of using a view is the best approach. To perform the update block, you have OHS 'Query' property only for your item derived to 'yes '. Witn, the column will not appear in any other dml. On lock... maybe the forms is no longer able to make a regular blocking when a block is based on a view. In this case, put a LOCK ON trigger on the block and lock the record for yourself to SELECT for NOWAIT UPDATE on registration. Just try if it would work, you use a NULL value in the POCKET ON right to xheck if dml himself operations will work. If your view is based on a single table, you have a good chance that there is nothing to change, if you get an error like 'Unmodifiable view', you need to make some additional adjustments
  -Choose the Mode key for the block to 'uneditable '.
  -Set the 'primary key' property to 'Yes' for the pk-point in your block.

• Oracle Forms Builder - YOU INSERT at the level of detail should take into account the change in amount level header

  Hello

  I have the form master / detail that are both at the level of the table.

  Header block has a MATCHED_AMOUNT column. Detail of block as DETAIL_AMOUNT.

  When the user inserts a record into the retail block, we conduct an insert statement in ONE INSERT trigger block of detail that makes integration with all the problems.

  Question is how can I get the DETAIL_AMOUNT newly added to MATCHED_AMOUNT. I tried to use UPDATE statement in trigger to INSERT the block of retail, but the UPDATE happens.

  Please suggest how to handle this logic.

  Thank you

  Sree...

  Ok.

  Remove the column MATCHED_AMOUNT of block shapes (if the point data base)

  Use INSERT after trigger to the block of retail and update the MATCHED_AMOUNT column to the database with the update command.

  Use a post REQUEST will trigger to the Header_block and show the MATCHED_AMOUNT in a display element with the SQL to the database.

  Hope this helps

• Is master detail in cascade LOV possible for details on a form?

  I have a form master detail to assign levels of skills to employees. Skill levels fall within areas. I have a LOV on the level of skills in the details, but I want to filter LOV skills by area, using a LOV cascading as follows:
  --------------------------------------------------------------------------------------------------------
  Master region
  Data on employees, etc..
  ---------------------------------------------------------------------------------------
  Detail region
  * [LOV domain] * {it is page-level element.  He appears only once on the page}
  
  * [skillset LOV] *... and other skills related fields {}
  * [skillset LOV] *... and other skills related fields {}
  * [skillset LOV] *... and other related skills fields {here are the details, many on each page}
  * [skillset LOV] *... and other skills related fields {}
  * [skillset LOV] *... and other skills related fields {}
  etc.
  
  [buttons, etc.]
  --------------------------------------------------------------------------------------------------------
  
  I added the page level [area LOV] element as part of the selection list. It works and is called P45_DOMAINS
  
  I then modified the query on the [skillset LOV] to add a where clause for the item clause:
  
  where DOMAIN =: P45_DOMAINS
  
  It does not work. [Skillset LOV] returns no data.

  Hello
  What version of Apex?

  If on 4.x then you did P45_DOMAINS LoV the Parent of the child LoV?

  If your form detail is a tabular form then LoVs cascading are not supported. You must build your own LoVs cascading using the technique from Denes Kubicek example here.

  See you soon,.

• Using wizard to create forms of master / detail

  Hi guys,.
  
  I'm using JHeadstart 11.1.1.3.35 and having major problems trying to create records of master / details in a layout of the wizard
  
  Department Master (shape, style Assistant, insert enabled, new line on entry)
  Group of retail employees (form, data dependant, allowed insert, update has allowed)
  
  Using schema HR with a view link between services and employees
  
  Main group Department (Assistant)
  = > Region of the element (all the fields of the Department)
  = > Region container
  = > Region group (Group of retail employees)
  
  (NB - if I used a group of the region as step in the wizard at a higher level, the following error occurred during the generation which is why I wrapped it in a container of the region...
  
  [NewDepartmentNewEmp.jsff, default/pageComponent/formRegionGroup.vm] Journal of speed [error] method pushModelPointer threw the exception of reference $JHS for model default/pageComponent/formRegionGroup.vm at [1,1]
  [NewDepartmentNewEmp.jsff, default/pageComponent/formRegionGroup.vm] org.apache.velocity.exception.MethodInvocationException: Invocation of method 'pushModelPointer' in class oracle.jheadstart.dt.jag.engine.velocity.JagEngineFacade threw exception class java.lang.NullPointerException: null
  
  The problem is that the detail of employee group does not start in design mode.
  
  I tried the create() method substitution in DepartmentsImpl
  
  protected void create (AttributeList attributeList) {}
  Super.Create (AttributeList);
  
  NewEmployee RowIterator = this.getEmployees ();
  NewRow row = newEmployee.createRow ();
  newEmployee.insertRow (newRow);
  }
  
  I also tried the override of the executeQueryForCollection method in detail (saw this solution suggested in another post on creating a form-form master / detail)
  
  protected void executeQueryForCollection (Object, object,
  Object [] bindParams,
  int i) {}
  super.executeQueryForCollection (object, bindParams, i);
  If (getEstimatedRowCount() == 0) {}
  Line = createRow().
  insertRow (row);
  row.setNewRowState (Row.STATUS_INITIALIZED);
  }
  }
  
  Nothing works well. I want to be able to use a wizard to create a record of master / detail in presentation view shape-to-shape. Is it possible, using a detail group, or do I have to create a separate view object that contains two master entity objects / detail in it and then just use the only VO in the Group Assistant of JHeadstart.
  
  This seems a very basic requirement, I clearly do something wrong!
  
  See you soon,.
  Brent

  Brent,

  To start in design mode, you must create the Group NewDeptEMp as a top-level group, so he will have his own taskflow. You can then define the new display line on the input property.

  In your wizard NewDept, you create a group of the region DIRECTLY under the container of the separatePages region, check "Include as ADFc region" then select the NewDeptEMp group.

  To work around the error that you got during the generation of the group in the region as an immediate child of the container sepeartePages, use the following code to formGroupRegion.vm:

  # revision_history
  # Steven Davelaar 28-sep-2011
  Additional support # 1.2 for the group in the region as child of separatePages region container
  Team JHeadstart # 30-sep-2006
  Historical revisions # 1.1 added, the basic version is 10.1.3.0.97 (SU1)

  #if ($JHS.page.itemRegion)
  #JHS_PARSE ($JHS.page.itemRegion.templateIdentifier $JHS.page.itemRegion)
  #elseif ($JHS.page.regionContainer)

• Form master / detail apex 5 tries to update the lines of details without apparent change

  A form master / detail of Apex default 5.0 creates buttons back and forward on the main table. When you move between records, the detail region launches a message: update 0 row (s), 0 or the inserted rows.

  Glance in occasional of the user, it will look like a mistake: I, what has changed and why it has not been saved?

  If nothing has changed, why is a MRU statement update being generated?

  How do I remove this behavior? Is this a bug?

• Unique constraint in the form of master detail error

  Hi all

  I need help, the following requirement.

  I have a master detail form developed on master-child table. the tables have the composite key.

  Old masters has a composite key on columns (A, B)

  Children table has a composite key on columns (A, B, C)

  Child block look something like below

  C       A          B

  10 AAA 1000

  20 1300 BBB

  30 CCC 1400

  40 DDD 1200

  Increments of column C with 10 for each record, and if a new record is insert in intermediaries the records it is incremented to 5.

  My requirement is when an end user attempts to insert record between 20 and 30 or 30 and 40 and clicks on save, the value of the C column must regenerate as shown below

  C       A          B

  10 AAA 1000

  20 1300 BBB

  XXX 30 900

  40 CCC 1400

  50 DDD 1200

  Button Save I wrote the following code

  Declare
    ln_Count NUMBER :=0;
    ln_c number :=0
    cursor c1 is
    select c
    from child
    where a=:child.a
    and b=:child.b
  Begin
    Go_Block('Child');
    First_Record;
    LOOP
    ln_Count:= ln_Count+10;
    :child.C := ln_Count;
    EXIT When :System.Last_Record = 'TRUE';
    Next_Record;
    END LOOP;
  
  
    For c_cur in c1 Loop
    update child
    set c:=ln_c+10
    where a=:child.a
    and b=:child.b 
    and c=c_cur.c
    end loop;
    Forms_DDL('commit');
       
       commit_prc('Commit');  -- We have our own program unit to call commit_form
  
  END;
  

  I tried above in a way because, before approving the changes to the table, I update the existing values in the table of the C column so I would not get unique constraint error.

  When you click the button Save, I get a constraint exception. Hope I made my requirement clear.

  Can someone give me a clue to this implementation.

  Thank you

  With this update, all your C-columnvalue became negative. When you post the form thereafter, forms update agaion records one by one the new positive figures. Because the numbers of 'old' in the db are now negative, there will be no violation-UK.

• How to create the column of the table for long-form Master detail relationship

  Apex 4.1

  Oracle 11g

  I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.

  Hotel_list

  ID HOTEL_NAME

  1 Holiday Inn

  Hotel Hilton 2

  Hotel_mapping

  ID HOTEL_NAME MAPPING_NAME

  1 Inn Holiday Inn Select hotel

  2 holiday hotel Holiday Inn Select

  3 hotel Holiday Inn Holiday Inn Hotel

  4 Hilton Hotel Hilton Hotel chain

  Hotel Hilton 5 HiltonHotel

  Table Hotel_name Hotel_list is a linked table Hotel_mapping

  When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.

  I would like to know, how to create the relationship?

  Thank you very much

  Best regards

  Yong Huang,

  simple step see creating a form detailed master with APEX - Assistant Master retail

  and check how to maintain the relationship between two tables,

  simple return the packaged application «Sample of Masters details»

  and try to understand this concept...

  In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping

  and maintain the relationship with the column ID...

  and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.

  otherwise the best way is to create sample on oracle.apex.com

  I hope this helps...

• Master / detail. Third do level not updated, if the second tier is not returned

  We have three level model master / detail.

  The first and the second level is 1 to 1

  The second and third are 1 to *.

  The second level is just an empty container from now and should not be displayed to the user. But it takes to get the first level to the third level.

  If make us only the first and third level tabulated, the iterator behind the third level table is not correctly being updated, actions.

  If we make on the other hand, the second-level table, the iterator for the third level table IS updated, to action - such as changing the current line.

  We worked arround by 'hide' the second table level in a group separator collapsed. Is there another way to get arround this problem?

  Top-level iterator:

  < iterator lie = "First" RangeSize = '25'

  DataControl = "AMDataControl" id = "FirstIterator".

  ChangeEventPolicy = "ppr" / >

  Second level iterator:

  < iterator lie = "Second" RangeSize = '25'

  DataControl = "AMDataControl" id = "SecondIterator".

  ChangeEventPolicy = "ppr" / >

  Third level iterator:

  < iterator lie = "Third" RangeSize = '25'

  DataControl = "AMDataControl."

  ID = "Third" ChangeEventPolicy = "ppr" / > "

  Not sure, but maybe you can use custom (for the first table) table selectionListener, I you must refresh the second iterator of pageDef...

• How to display two dept details at the same time in the form of master-detail

  Hi Experts

  In Forms 6I, using the Scott schema, table DEPT & EMP has created a simple form of master-details relationships.

  Currently when user Dept Block shows all lines dept and EMP block display data based on the selection of deptno.

  It's only a deptno both.

  If the user in the No. 10, block EMP Dept will display all the data related to 10

  If the user moves to 20 Deptno, block EMP will display all the data related to 20.

  And so on.

  But our requirement, what happens if we want to see the 10 and 20 at once (both several deptno)

  Thank you

  Thanks for your information.

  In fact, our requirement is only to display data, he own be no matter what update of data/insertion.

  So below and working for our requirement

  • Remove relationship
  • Additional box on master block.
  • Write code cursor on the box selection - which will fill/clear data block information based on the checkbox selection on block Master.

  So, it's a "bug"?

  Probably something to do with the creation of forms of master-detail using ROWID instead of a real process of generated by the wizard of PK. APEX theory. PKs relational DB meaningful, immutable like immutable PKs. Despite the bug condition region of detail, is why your column editable PROC_NM if it is used as the PK? It is a good way to break things. (I created now orphaned detail rows).

  If you want to take advantage of the built-in features of APEX as ARP and MRU wizard-generated process, then go with the flow: use surrogate keys. Otherwise you'll spend your time to write a lot of code manual.
