  Hello

  I read on how to do to remove a compressed table column - first set unused and then drop unused columns. However, in the example below on the basis of data, I ran it, it does not work. Please, can you tell me WHEN this approach does not work. What is dependent on - settings or something else. Why can't I drop unused columns?

  And the example and errors:

  create table tcompressed compress in select * from all_users;

  > TCOMPRESSED table created.

  ALTER table tcompressed add x number;

  > table TCOMPRESSED altered.

  ALTER table tcompressed drop the x column;

  >

  Error report:

  SQL error: ORA-39726: unsupported operation column add/drag on compressed tables

  39726 00000 - "operation column add/drop not supported on compressed tables. ''

  * Cause: Not support add/column operation move compressed tables

  elapse.

  * Action: When adding a column, do not specify a default value.

  DELETE column is only supported in a column SET UNUSED

  (remove the column metadata).

  ALTER table tcompressed unused column of the set x;

  > table TCOMPRESSED altered.

  ALTER table tcompressed drop unused columns;

  >

  Error report:

  SQL error: ORA-39726: unsupported operation column add/drag on compressed tables

  39726 00000 - "operation column add/drop not supported on compressed tables. ''

  * Cause: Not support add/column operation move compressed tables

  elapse.

  DELETE column is only supported in a column SET UNUSED

  As you can see even after changing the table defining the column as unused X I still can't drop by DROP UNUSED COLUMNS.

  Thank you.

  If you enable compression for all operations on a table, you can delete the columns in the table. If you enable compression for the only direct-path inserts, you can't remove columns.

• Hide column to a specific user in 9i

  Hi all
  
  Oracle 10g implements column masking with the SPV, but same functionality is not available in 9i. Does anyone have any suggestions on how I can implement the masking of the column (from a specific user) in Oracle 9i?

  Does anyone have any suggestions on how I can implement the masking of the column (from a specific user) in Oracle 9i?

  Unfortunately, your only option is to create a view for that user that selects only the columns that you want them to see.

• 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

• JTable with custom column model and model table does not display the table header

  See http://download.oracle.com/javase/6/docs/api/javax/swing/table/TableColumn.html#setHeaderValue (java.lang.Object)
  When the TableColumn is created, the default headerValue is null
  So the header ends up rendered empty label (probably of size 0 if the JTable calculates its size of header based on the size of the default rendering tool).

  It worked:

       private static DefaultTableColumnModel createTestColumnModel()
       {
            DefaultTableColumnModel columnModel=new DefaultTableColumnModel();
                  TableColumn col = new TableColumn(0);
                  col.setHeaderValue("Header Title");
            columnModel.addColumn(col);
                  return columnModel;
       }

• display / hide column of the table running

  Are there known issues with display / hide a column of the table at run time?

  I have a table that contains a column with a check box and another with a radio button.  If the user is allowed to select more than one row in the table (as indicated by a form variable), then I want to hide the column of radio and checkbox column.  If not, I want to show / hide the contrary.

  I show / hide the column header too.  When I preview the form, however, the data in the table appears "scoot" left and placed in the column that is hidden, so to speak.

  Here is a view of the design of the table:

  

  And a view of the execution of the table.  You can see the radio is hidden, but the "account number" column wants to crush in the (hidden) radio column,

  

  Here is the script, I'm very confident in this small snippet of code because the lines of account were filling wonderfully until I added the column of radio buttons and the script to show/hide.

  Put the account data in the table

  function

  setAccountData (objAccountRow, objAccountItem) //Pass in the line and data to complete line

  {

  stuff the line

  objAccountRow.accountNumber.rawValue

  = objAccountItem.accountNumber;

  objAccountRow.accountName.rawValue

  = objAccountItem.accountName;

  objAccountRow.accountBalance.rawValue

  = objAccountItem.accountBalance;

  display the check box or radio button, depending on the number of accounts they are allowed to select (as specified by the form variable)

  var searchNumAccounts = objFragment.resolveNode("searchNumAccounts").value; Variable //Form

      if (searchNumAccounts==1)

  { //show the column of radio buttons and hide the checkbox column }

  hideObject (objResultsSubform.accounts.HeaderRow.txtSelect);   <-it's exaggerated here, to hide the table for each row header column,...

  hideObject (objAccountRow.accountSelected);

  showObject (objResultsSubform.accounts.HeaderRow.txtRadioSelect);

  showObject (objAccountRow.radioSubform.radioGroup.selected);

  }

  on the other

  { //show the checkbox column and hide the column of radio }

  hideObject (objResultsSubform.accounts.HeaderRow.txtRadioSelect);

  hideObject (objAccountRow.radioSubform.radioGroup.selected);

  showObject (objResultsSubform.accounts.HeaderRow.txtSelect);

  showObject (objAccountRow.accountSelected);

  }

  }

  OK I got it. The table object implements a container to contain the fields. You hid the ok fields, but you then never reset the row in the table to have only two columns. I copied the parameter of the XML source so that I would have the exact width and then deleted the one I wanted to hide. Now everything works fine.

  See the example updated the.

• How to add a column to a specific location within a table using Sql developer.

  Hello
  
  I need to add a column to a table in a specific location, how to proceed?
  I tried following

  where move column up and down column options are disabled.
  can someone help me with this.
  
  
  Thank you

  Its not supported. In the database to insert a column in a specific location, you must re-create the table and SQL Developer team have, decided quite rightly, it is a step away.

  Remember in connection with the database column order is not serious.

• Need to change column Datatype on external Table

  Hi - I need to change a data type of column on an external table and I have a few questions.
  
  1. I've read that I can do a regular alter table change column statement, but I also see in the script behind the external table, the following instructions:
  

   FIELDS  MISSING FIELD VALUES ARE NULL(
          claim_number           POSITION(1-12)   INTEGER EXTERNAL(12),
          receipt_date           POSITION(13-8)   INTEGER EXTERNAL(8),
  ........

  When I run the statement column change he does not alter the column but does nothing in this clause. Is it possible to update this info as well?
  
  I wonder also (currently working at dev with a specification of invalid directory - soon to solve) - will I encounter a problem if I try to edit my article, if a file is located in the related directory? I ask because I know that to change the data type of the existing column in a table standard you must first set this null column, so I wonder how this rul applies when it is an external table.
  
  Thank you!
  Christine

  An external table does not store any data. The external file that contains data is only available at query time. You can remove the outer table and re-create it to change both the data type of the column in the table and the type of data in the file. using the statement ALTER TABLE... Type MODIFY instruction, you can modify the data of table column. You can also change the definition of the external table if the file is stored in the direcory and ready to be read through the external table.

  In an ordinary table, you can decrease the length of the column if the column is no longer, then the new column length:

  SQL >desc test
  Nome                Nullo? Tipo
  ----------------- -------- ------------
  A                 NOT NULL NUMBER

• Hide the headings for specific users/groups

  Hello
  
  Is this possible with WEBhelp, hide/Exclude subjects for specific user groups / users?
  
  Currently, we use html/chm help. There is a project for our main software. I have another project for an add-on that is integrated in the table of contents of the main project using the merged help function. We only install help for this module when the customer has purchased this module. So the customers who do not have this module do not have help to make it.
  
  It is possible something similar with WEBhelp (Pro)? I ask because we go to WEBhelp (Pro). In this case, there is no help by the customer file, but one for all the world. Is there a way to display only the additional items to customers who use this module?
  
  * The only way I can think is to integrate all this into a single project and publish twice (one with and one without the themes of the additional module) using the tags of the construction. Or is there a way to let the RoboEngine/RoboServer merger it on the fly, but based on the criterion that the customer has the module?
  * This additional help project can be added to the main help as a teaser for other customers also use this module (others cannot buy unless you are a franchisor of a group of specific hotel for which we have developed the module)
  
  Thank you

  Hi John-Pierre. RoboServer this is impossible on the fly. Tags of the generation are the way to go. Simply create a new tag, apply it on the subjects you want no franchises user to see, then apply the tag to your SSL to exclude it from the output. Viola, you have your username not franchisees to help. Simply remove this label from construction of the SSL for users of franchises so that they get everything. You can also create two identical WehHelp Pro SSL - 1 vote against and no label construction and the other with a construction tag to avoid you to have to remember to add/remove.

  How your application will know files that help write? Is this a separate executable? I know that it is possible for the INSTALLATION. EXE to check the license before installing the modules, but I never went to the bottom of this line.

  BTW, build tags can be used on all types of output.

• Show hide columns generates error on the page if not found data

  Hello
  
  Has anyone ever encountered a situation where a page error when using the feature show hide column and no data is returned.
  
  My region to report is based on SQL and when calling at the start page or when restrictions are no match all all the data that appears is the message "No data found" by default. The method used, I pulled Carl Backstrom (RIP) application.
  
  < script type = "text/javascript" >
  function html_HideBasedOnCheckBox (pThis, pThat) {}
  if(pThis.Checked == true) {}
  html_ShowCellColumn (pThat);
  } else {}
  html_HideCellColumn (pThat);
  }
  }
  
  function getCellIndex (pRow, pCell) {}
  If (document.all) {}
  for (var i = 0; i < pRow.cells.length; i ++) {}
  If (pRow.cells [i] == pCell) {l_Count = i}
  }
  } else {}
  l_Count = pCell.cellIndex;
  }
  Return l_Count;
  }
  
  function html_HideCellColumn (pId) {}
  var l_Cell = $x (pId);
  var l_Table = html_CascadeUpTill (l_Cell, 'TABLE');
  var l_Rows = l_Table.rows;
  l_CellI = getCellIndex (l_Cell.parentNode, l_Cell);
  
  for (var i = 0; i < l_Rows.length - 1; i ++) {}
  html_HideElement (l_Rows.cells [l_CellI]);
  }
  return;
  }
  
  function html_ShowCellColumn (pId) {}
  var l_Cell = $x (pId);
  var l_Table = html_CascadeUpTill (l_Cell, 'TABLE');
  var l_Rows = l_Table.rows;
  l_CellI = getCellIndex (l_Cell.parentNode, l_Cell);
  
  for (var i = 0; i < l_Rows.length - 1; i ++) {}
  html_ShowElement (l_Rows [i]. Cells [l_CellI]);
  }
  return;
  }
  
  < /script >
  
  The attributes of HTML form elements is: onclick = "html_HideBasedOnCheckBox (this, this.value)" "
  
  The LoV for this box is static for a column.
  
  This set works very well if the data is returned. It must have something to do with the topics defined in the SQL code and therefore are not displayed when no data is returned. The code is then try to hide or something that does not exist.
  
  The part where he falls is during the setting of the variables:
  
  function html_HideCellColumn (pId) {}
  var l_Cell = $x (pId);
  var l_Table = html_CascadeUpTill (l_Cell, 'TABLE');
  var l_Rows = l_Table.rows;
  l_CellI = getCellIndex (l_Cell.parentNode, l_Cell);
  
  ... and more specifically the last variable setting: l_CellI = getCellIndex (l_Cell.parentNode, l_Cell);
  
  Does anyone know how I can get around this by using the method of SQL report i.e. Select col1 col2 "Column 1", "column 2" From myTable etc. or if it is possible to make up for it at the beginning that is
  
  If NO_DATA
  then
  dont_hide/display_any_columns that_dont_exist
  on the other
  var l_Cell = $x (pId);
  var l_Table = html_CascadeUpTill (l_Cell, 'TABLE');
  var l_Rows = l_Table.rows;
  l_CellI = getCellIndex (l_Cell.parentNode, l_Cell);
  
  for (var i = 0; i < l_Rows.length - 1; i ++) {}
  html_ShowElement (l_Rows [i]. Cells [l_CellI]);
  }
  return; ........
  
  ???
  
  See you soon,.
  
  Mike

  Hi Mike,.

  In fact, you can check the existence of the cell:

  var l_Cell = $x(pId);
  if (l_Cell)
  {
   rest of the code to hide the column
  }
  

  As long as l_Cell makes reference to a valid page element, then the if test passes and the rest of your code can work.

• remove the column in csv

  No one knows how to delete a column, or changing the values in this column and leave the rest in a csv file?

  Example:

  CSV file has 70 rows and 40 columns. To remove a column or change its values.

  Thanks in advance.

  Yes, I did a quick VI, which is a combination of the cross and methods Happies, takes the whole CSV in memory in the form of a table and it then passes out CSV again to another. If you want to make any changes to the CSV just deal with it even as you would a table when she goes from one CSV to another.
