• If the data is empty when you use to_date(?,'yyyy/mm/dd') insert a file into db

  online form insert the? is user input, if the user entered the following works find, but if the input file is empty insert get an error, how to handle
  If the data is empty when you use to_date(?,'yyyy/mm/dd')
  Thank you

  Be more specific.

  You try to insert this in a column that is defined as not null?

  If so, you can choose a default value for the value that you want to use if the user leaves the field to the white screen.

  Or, better yet, use the validation of the front to prevent them from going into an empty space (or perhaps failed it there).

  However, if you still want to do it in the DB:

  Insert into table1 (non_null_date_col)
  values (to_date (nvl (?, '' 2199/12/31), "dd/mm/yyyy"));

• You can use the table of exception when you activate a FK constraint?

  Anyone know if its possible to use the exception table when you activate a FK constraint? I know that it works to allow a first key constraint, but have not been able to operate to allow a FK constraint. BTW, we use Oracle 11 GR 2.

  Works for me.

• Premiere Pro cs6 - video pane of the workspace remains empty when you try to view the imported files

  Hello

  I am currently working in Adobe Premiere Pro CS6. When I import my media into my workspace and drag it into the timeline, the preview area where you can review your cup video remains black. Double-click the imported file gives the same result. I was initially import files .jpg (about 300 KB of size for each) so I tried to import various other image formats - .png, .tiff, etc... I even imported a my scene movie file to determine if the problem was with my format of content. With video, the audio plays fine, but the video remains empty in the preview area. I tried rendering my workspace and change my initial parameters of the project, but to no avail. I went to my preferences for first and far as I know, everything seems fine.

  I use the software on a HP Pavilion, Windows 7 intel core i7, 8 GB of ram with a 2 GB of 650 M from nvidia card. Any help would be greatly appreciated. Thank you!

  Hello

  Have you tried to change your Video Renderer? It would be under the project > project settings > general. Switch option only the Mercury playback engine software and see if it helps.

• Problem updated 16 rows, it updates all rows in the table

  I tried to update of 16 ranks with AL as the name of divion with the script as below:
  
  Update wire_center set a.wg_id = '63'
  where EXISTS (select b.div_name from wire_center, title b, area c, ns_workgroups d).
  where B.DIV_NAME =' al ' AND a.dis_id = c.dis_id and b.div_id = c.div_id and d.wg_id = a.wg_id);
  
  When I run it, it updates all rows in the table.
  
  However when I run the select subquery, it returns 16 ranks.
  
  It seems where EXISTS is the problem. If I exist, it gave me error ora-00936.
  
  How to fix? Need urgent help please. DB is 10g.
  
  Thanks in advance.

  If I understand correctly what you want, you must not include wire_center once again in the second select (in your clause).
  The second selection has no relationship to the table you're updating, so because select the second returns 16 rows, it is always set to true will. For each line. If all the rows will be updated.

  Instead of

  Update wire_center a set a.wg_id='63'
  where EXISTS (select b.div_name from wire_center a, division b, district c, ns_workgroups d
  where B.DIV_NAME='AL' AND a.dis_id=c.dis_id and b.div_id=c.div_id and d.wg_id=a.wg_id );
  

  Try this:

  Update wire_center a set a.wg_id='63'
  where EXISTS (select b.div_name from division b, district c, ns_workgroups d
  where B.DIV_NAME='AL' AND a.dis_id=c.dis_id and b.div_id=c.div_id and d.wg_id=a.wg_id );

• I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help

  I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help

  I don't understand. You use vo and eo for you to use business components.

  Again, this kind of code call in trouble.

  You must post the changes to make them visible to the eo find vo. You must then run the query for the changes in the business layer strips then you must update the iterator he table is based on.

  In your code I see that happen, hooch maybe because it is more often than not formatted and undocumented.

  My advice is to do a small test case that you can manage with easy sql. Once you get it to run transfer you the results to the actual application.

  Surprisingly, it works very well if there are lines in the table that the VO is querying.

  Soham,

  I think you just create this LOV page by simply moving the VO, right?

  You can select the box to tick 'Include no. Selection' in your VO, and see if that helps?

• Rows in the table are break on separate pages...

  I have 20 lines equipped table:

  first 3 lines are on one page, then half of the page is empty hen remaining 17 rows is on the second page.

  How can I keep table to break the lines. I want all rows in the table to succeed himself.

  Help, please. Thank you.

  Keep them with parameters are in the table > Format > Format line...

  

  Note: the first row on the second page may also have a start parameter that indicates that it is at the top of a page or column.

  The control of widows and orphans just specifies how many rows to keep together (widow is the first page; ( orphan , is the second page) when a table has over a page. The higher the number, the more lines are forced to remain together.

• AF: displays do not all rows in the table

  Hi all

  I have an af table in my jsff and it is bound to a display object. When I run the page locally in my jdev the table af shows all lines present in the ViewObject. But when I deploy the application in our SIT weblogic break page maximum of 25 lines shows if VO has more than 25 lines.

  I put the size of the VO - 1 range. The size of range iterator is empty. I'm naïve why he works in local jdev and does not not in SIT.

  A level of the application or the server parameter influences the number of lines to display in the table.

  Thank you

• Rows in the table LT until merger of all workspaces

  Database 11.2.0.4

  In our environment, we ran a few important updates in the workspaces and then merged these live workspaces.  Up to 25% of the data has been updated in those workspaces.  When these update batch workspaces have been created, previous workspaces exist who are not yet ready for the merger.

  I noticed that the underlying tables of the LT now have about 25% more lines than the live view.  We have now discovered that dbms_wm.refreshWorkspace works really poor.  This statement is used to take seconds or minutes to the maximum, but can now take half an hour or more.

  We recorded a support with Oracle request and provided details of the plan to see if we can get some resolution/advice explaining.

  In the meantime, I have a question for the forum help my understanding of the works of the Manager of the workspace.

  In the example below, I have table "wm_test_table", "test_workspace1" and "test_workspace2".  In "test_workspace1", I update all rows in the table - the table LT now has 2 rows for each record.  I merge 'test_workspace1' live and LT still has 2 rows for each record.  The other lines are not removed until "test_workspace2" is merged and removed.

  Is it possible to safely remove the extra lines in LT without waiting until we merged the workspaces that existed before the update batch has been done?  I hope that it will so improve the performance of refreshWorkspace.

  
  

  I thought that something like this can do, but it does not remove the other ranks, is:
  

  execute dbms_wm.PurgeTable(
   table_id => 'test.wm_test_table', 
   archive_table => null, 
   where_clause => 'id not in (select id from test.wm_test_table)', 
   instant=>null, 
   workspace => 'LIVE', 
   purgeAfter => false);
  

  This question is similar to

  Lines left in the table LT after removal of the direct workspace and the removal of all workspaces

  and

  How to delete soft deleted records?

  but I'm still not sure.

  Thank you

  John

  Hello

  This behavior is expected and it is due to the test_workspace2 workspace.  A compression operation will not allow compressed range to include a backup implicit point that is created for a child workspace.  This is done to preserve the integrity of this workspace.  The initial 1000 lines are all lines that are visible from test_workspace2.  Removal of these lines would leave test_workspace2 will 0 lines in there.  Lines 1000 updates are the lines that do not appear on LIVE.  So, given that the two sets of lines are needed, none of the lines can be deleted physically.  A compression operation will never change the view of data for any workspace.  It only removes the unnecessary records.  The two options in order to be able to compress these lines is to either delete (as you did) or refresh test_workspace2.  The refresh operation would move the implicit savepoint for the workspace to a version that isn't after all 2000 lines in the table _LT and allow the dressing to remove first half of them because they are no longer needed by any child workspace.

  With respect to the performance of RefreshWorkspace, I would need to see a trace of the transaction file.  But who should rather get through the SR you filed.

  Kind regards

• ADF: Double in taskflow Page Navigation click on the row in the table on the page .jsff

• Select the row in the table to change in a form

  Hi all

  I use Jdeveloper 12.1.3.0.0 on windows internet explore 10.

  I have the following form and the read-only table. the form and the table that are both on the same object from view.

  

  When the user clicks a row in the table, I want to choose this line in the form above for editing purpose.

  How would I do that? the first column of the table is a primary key.

  I followed shayjdev vedio http://www.youtube.com/watch?v=e0IcnXLJUgU

  but the problem is that when I click the button CreateInsert (5th button left in my case), never clear the form for the opening of new record, instead, he put the table in input mode.

  kindly help me with this.

  Thank you.

  To create a new line, you drag the operation createInsert of the data control on the create new"" button. This should create the new row.  If you like the new line being the last of them using the link from dvohra21 to https://blogs.oracle.com/jdevotnharvest/entry/how_to_add_new_adf

  In this case, you must change the listener to the button action to point to the generation of listener action code of Frank.

When it is run the code: dragRow.removeAndRetain () in the method: DnDAction processDrop (DropEvent dropEvent), it throws the error so that a guest view object is read-only. I want to know if there is another way to delete the moved collection line?

   public DnDAction processDrop(DropEvent dropEvent) {
  ...       
         CollectionModel collectionModel = (CollectionModel) table.getValue();        
          JUCtrlHierBinding treeBinding = (JUCtrlHierBinding) collectionModel.getWrappedData();
          
          //get access to the ADF iterator binding used by the table and the underlying RowSetIterator.
          //The RowSetIterator allows us to remove and re-instert the dragged row
          DCIteratorBinding departmentsIterator = treeBinding.getDCIteratorBinding();               
          RowSetIterator rsi = departmentsIterator.getRowSetIterator(); 
  
          int indexOfDropRow= rsi.getRangeIndexOf(dropRow);
         //get access to the oracle.jbo.Row instance represneting this table row
         Row dragRow = (ViewRowImpl)table.getRowData(draggedRowKey);
         //remove dragged row from collection so it can be added back
         dragRow.removeAndRetain();
         rsi.insertRowAtRangeIndex(indexOfDropRow, dragRow);
        ...
  }
  

  2. When you click on a button, I need to save the command results in the database using the command update # of each rank. Here it is the handler method for the event of the action (in MB) button.

  I want to use RowSetIterator table for encode it from all ranks and update the value # order of each rank.   I call a data control method to run sql update. is it ok? any suggestion?

      public void processSaveOrder(ActionEvent actionEvent) {
          CollectionModel collectionModel = (CollectionModel) mytable.getValue();        
          JUCtrlHierBinding treeBinding = (JUCtrlHierBinding) collectionModel.getWrappedData();
          
          //get access to the ADF iterator binding used by the table and the underlying RowSetIterator.
          //The RowSetIterator allows us to remove and re-instert the dragged row
          DCIteratorBinding iterator = treeBinding.getDCIteratorBinding();               
          RowSetIterator rsi = iterator.getRowSetIterator();
          Row row =rsi.first();
          System.out.println(0+"="+ row);
          int i = 1;
          while(rsi.hasNext()){
              row = rsi.next();
              System.out.println(i+"="+ row.getKey());
              i++;
          }
  
      }
  

  A workaround solution was found:

  In ADF 12 c, it can be solved by changing Updatable "Always" in the details tab of each attributes to read-only view object without entity object.
