• number of rows in the table

  Hi master,

  I have a requirement. During the passage of a table, I need to get the number of rows in this table. Sometimes, when I spend 2 or more table names, I need to get the same count of result of lines. I got the below function. but it shows all the rows in the table. I want pariticular tabels only. How I can I get it.

  Select table_name, num_rows from all_tables where table_name in ('EMP', 'Department');  I tried.  I need to a procedure or function. who will pass the name of the table as a parameter and 1 or more than the name of a table if I pass, I need to display information from table name and number of lines.

• 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.

  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

  I think that because we have performed 83 times, then the value of "lines" should be:
  83 x number_of_rows_in_table = 83 x 3138 = * 260454 *.
  
  What we have is 260371, who looks like me:
  3137 = 83 x 83 x ( number_of_rows_in_table - 1 )
  
  
  I misinterpreted the news (I guess I!)?
  
  Why seems to be number_of_rows_in_table - 1 ? (Or is it pure coincidence?)

• Hide columns in Table B, based on values LOV in another row of the table:

  Hello

  Jdev 12.2.1.0

  I have two tables A and B and I hide columns b based on the value of row of table A LOV. For example, I have a line in A table that has a column with the x, y, z values lov. Now, if I select the row in the table has and change the LOV to x, I had to hide some of the columns in the table (B) is there a way to get this feature? Any help would be appreciated.

  Thank you

  Assume:

  1 table a call "DepartmentId" column this column has LOV.

  B 2-table a column "ColumnInB" this column will be visible depending on the value of "DepartmentId".

  Try to do the following:

  1 - from data controls, drag "DepartmentId" attribute and drop it on the page as inputText then together make this inputText to false (you can remove it, but don't forget the corresponding binding in pageDef. not deleted).

  2. copy the value of the inputText which will be as "#{bindings." DepartmentId.inputValue}"and go to the"ColumnInB"column and visible property beyond the copied value.

  3 - the ColumnInB visible will be the condition as:

  4-set DepartmentId autoSubmit = 'true '.

  5-set table partialTriggers table B has id and id of DepartmentId LOV

• 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?

• problem of adjustment of height of the rows in the tables in CS6

  I read all the debates devoted to setting the height of the rows in the tables and I can't find the answer to my problem.

  I placed a table that was created in Word.  I've done several times, but now I can not adjust the heights of less than 5mm line without losing the text in the line.  I went up to line on "exactly".  As soon as I try to reduce the height of the text disappears, but there is plenty of space above and below the text.   Hoping someone can help.

• 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.

  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.

• Questions about the reorganization of the rows in the table by drag-and - drop feature

  I am referring to the demo: 106. Drag-and-drop the reorganization of the rows of the table in aCorner of Code DF to implement my case.

  I am facing some problems:

  1. the view object (bound to the table) is read only and it is created directly by very complex SQL queries, without entity objects. 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.
