• How to avoid the chained rows

  Hi all
  
  I have problems with the lines chained on an instance of customer. I did the analysis and I've identified the tables involved. I prepare a small script with the various necessary ALTER TABLE MOVE for each table, increasing their pct_free and pct_used parameters.
  
  I take the idea of this article: http://www.akadia.com/services/ora_chained_rows.html
  
  The script have different sentences like this: ALTER TABLE CASASCONJARDIN. USERS MOVE PCT_USED 50 PCT_FREE 20; (one for each table)
  
  The first sentence has been completed successfully, but the faild remains with the following error:
  
  ERROR on line 1:
  ORA-14133: ALTER TABLE MOVE can not be combined with other operations
  
  Where is my mistake? Why I could execute the first order but not the rest? How can I solve my problem of chained rows?
  
  Kind regards
  Jordi

  Hello

  ALTER TABLE CASASCONJARDIN.USERS MOVE PCT_USED 50 PCT_FREE 20
  

  Not sure that you used the syntax
  but the correct syntax is

  ALTER TABLE CASASCONJARDIN.USERS MOVE PCTUSED 50 PCTFREE 20
  

  You have your additional syntax "_".

• How to set the table rows spacing and line changing automatically if is limit

  Greetings,

  I use JDeveloper 11.1.2.4. By default, if you set (or not) the table width and the line is its width, it will create a scroll down bar.

  Is what I want to do, if the text inside each row its greatest width, to change the line inside his line. TO

  more to explain it, I'll demonstrate a small table below:

  MESSAGE ID

  1 Hello Philip

  2 Hello Philip

  3 How are yo

  u today?

  4 tries...

  This way, if the text in the column 'message' is the largest say width 40, to increase his height of line automatically if the text

  fits inside 1 row without creating a scroll bar.

  Thanks in advance for any help.

• Make it visible only works field in the first row, not added lines

  I have a dynamic form that I can add lines. It is 3 columns, the first being a DOF that fills the second column DDL. The 3rd column is a hidden field that shows once made a choice in the second DDL. It works very well in the original line, but it will become visible in the rows that are added.

  This is my code for the second DDL:

  If

  (this.rawValue ! = 1)

  {

  Form1. Page1.OrderSection.OrderItems.condition.presence

  = 'visible ';

  }

  on the other

  {

  Form1. Page1.OrderSection.OrderItems.condition.presence

  = 'hidden ';

  }

  Must be set up as a sort of loop maybe? I'm sure it has something to do with my being a dynamic path name path. Not really sure at this point what to look at to make it work. I don't know how or if I can get my file here. If someone can tell me how to fix it, or I can email to someone for help.

  Thanks in advance.

  Each object must have a unique name. To accomplish the repeating subform Gets a number of occurrence, so assuming the OrderItems is the repeated subform expression to get the object will be OrderItems [occuranceNumber]. Condition

  If you need to change your code to access the instance on the right:

  'visible ';

  xfa.resolveNode ("form1. ("Page1.OrderSection.OrderItems [' + this.parent.index + '"] '). Condition.presence =

  Assuming that you are running this code on an object inside the subform. The this.parent.index will give you the index number of the subform that you are.

  Hope that helps

• Store the new values in the table in the new row so that the 'old' remains in the previous lines

  Hello

  I am a student of genius embedded. I did a VI where I change the values of digital controls, and it saves it as a table.
  I want to store the pair of new values in the new row of this table.
  I have attached a VI where I can change the values of numeric control, as well as the number of lines from another control. But when I change the values, all values in the output table change including values in the previous row. I want these lines to be unchanged and that new line to update.

  Need help.

  If I understand correctly, you want to always 4 models. If so a 2D table will do the trick (see annex VI), otherwise crossrulz' solution should work.

• ListField.drawListRow only draws a line in the first row, all the lines.

  I'm close. ListField.drawListRow is called for every row without problem, but the two graphics.drawLine only are displayed (shot) in the first row at the point of coordinates noted.

  I thought that each line would get the two drawn drawLines?

  3. in your bookmark create button to create only one line NOT 2 rows.

  4 - Open the object entity--> java--> java class--> on the entity object class generate and Tick tick on the accessors and methods of data manipulation

  Hello

  You can use the analytical function of LEAD (or GAL) to get the difference between hours.

  For the results in the form of 3 columns in 1 line (rather than 1 column on 3 rows) calculates the LEAD in a subquery.  In the same auxiliary request, you can use the function ROW_NUMBER analytic number lines 1, 2 and 3.  The main query then use this value to rotate out of the subquery.

  Depending on your data, your needs and your version of Oracle, it will be something like this:

  WITH got_analytics AS

  (

  SELECT stock

  LEAD (header_2) (PARTITION OF BOUILLON

  ORDER BY header_2

  ) - header_3 AS time_diff

  ROW_NUMBER () (PARTITION OF BROTH

  ORDER BY header_2

  ) AS r_num

  FROM my_table

  )

  SELECT *.

  OF got_analytics

  PIVOT (MIN (time_diff)

  FOR r_num (1, 2, 3)

  )

  ;

  I hope that answers your question.

  If this isn't the case, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.

  Explain, using specific examples, how you get these results from these data.

  Make sure that your sample data reflect important aspects of your actual data.  For example, in your actual data, you have probably different values in the column actions. Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• ExportCollectionAction causes the current values of lines to be copied into the first row of the table

  Greetings experts,

  I use JDev 11.1.2.3

  I am faced with a really strange behavior of the exportCollectionActionListener. I have a table for each row in this table, a link that calls a popUp. This popUp tells the story of this selected save changes (means it displays data from a different table/VO, who keeps a history of the first) in a table. I have a button that calls the exportCollection for this second table. When I press on it, an excel file is generated and downloaded and everything is perfect until now. If there was not any which record in this table, and o back to the first, by pressing the button send is not track all changes. But if there where all records from this table of history (always talking about the history of the current line), go back to the first and press on submit, that the very first line of the table of fir trees, gets all of it's values as the last row of the second table, as it is copied from one to the other. I have to press on restore back to normal (note that the popUp has it's CancelListener to call a restore of a bean to support operation).

  Why is this happening?

  Thanks in advance

  I found a work around for this problem.

  I added the code that causes the whole view Refresh (ie: the whole page), the popUp cancelListener, also I changed the commandLink partialSubmit property and set it to true. It's not like totally cool watching the screen charge for this fragment of a second after the closure of the pop-up window, but it not the drill.

  See + {: identifier of the thread = 1116477} +.

  Sorry, I forgot all that when I suggested that you can use a custom here report model (not surprisingly, since I did not use the tabular forms given that these changes have been made).

  I don't remember see potential customization discussed in 4.1 or 4.2 (but then I would not have all these tabular forms).

  If your options seem to be:

• Using nested tables as suggested by mark, who introduced the downside to Peter about the width of the columns (you can try to remedy using CSS to create fixed-width tables/columns, but my last experience of this receipt very messy in terms of support of IE cross-browser and legacy...)
  
• Build the page completely manually without the help of the features integrated in the form of the APEX.
  
• Try to customize the behavior of line add to take into account the layout is customized using the dynamics of the actions/jQuery.
  
• Do not use the tabular forms.

• How can I configure only the first row of a DataGrid as the selected line?

  I have a "Go" button on a search form that retrieves data in a grid, already linked to data.  After the data is read, I want to make the first line in the Datagrid control in the selected row, as if the user has clicked on it.  If the result set is empty, I don't want the code down.  (I want only one line can be selected at a time)

  That should do it.
