• change the data type of a column

  Since the previous post: how to change the data type of column number to varchar2 in oracle10g
  
  Measures may be:
  create table TestTable (ColA varchar2 (5));
  Insert into TestTable values('12345');
  
  ALTER table TestTable Add (ColATemp number (5));
  setting a day of TestTable set ColATemp = ColA;
  
  ALTER table TestTable remove column ColA;
  change the column in table TestTable rename ColATemp CLC;
  
  My question is:
  If the table half million records
  
  setting a day of TestTable set ColATemp = ColA;
  
  will it be a good solution? Any performance issues? There is no index on this column.

  Sort while you do DDL, you will not be able to do any operation on the table. You the best suites you. It's a time operation, you can change the table to change the data type, but it may not work if some of the data in the table confirms no new data type of column.

  First, you must open a ticket with oracle Support and explore the options

  You can use this note to fix:

  If you are unable to drop Undo tablespace as Undo Segment recovery must

  You can download the trace file following the opening of the ticket

• How to get the data type of an object?

  I have some custom classes, and I would like to make conditional function that behaves differently depending on the data type of the object. How can I do this?

  you could do something like

  If (obj is Objetpersonnalise)

  {

  or you could look at using getQualifiedClassName() or getDefinitionByName()

  I'm trying to update the date in a data template on a user clicks the button, but unfortunately the Date() function gives just a format long unncesseray.  I want just the day/month/year (i.e. 10/09/2013).  How to change the Date() function to achieve this?

  I was actually able to find a workaround simpler.  I just used objects attached within the key and attached to a date function:

  Button {
  
                                      imageSource: "asset:///images/ic_add.png"
                                      onClicked: {
  
                                          rootItem.ListItem.view.getApp().updateObject(ListItemData.customerID, ListItemData.name, ListItemData.description, datefield3.text, parseInt(ListItemData.lat) + 1, ListItemData.lon, ListItemData.categorySelect, ListItemData.mapurl)
  
                                      }
                                      attachedObjects: [
                                          Label {
                                              id: datefield3
                                              text: {
                                                  var today = new Date();
                                                  (today.getMonth() + 1) + "/" + today.getDate() + "/" + (today.getFullYear() - 2000);
                                              }
  
                                          }

• How to set the date type date of work

  This is perhaps a silly question, but I can't seem to get the data type date to work for a member account. When I go to the planning application and choose an account I want to put in a date entry account, the web form seems to show that the setting of the date works for the account. I even put my account type to be saved hypothesis. For example, I expect to see the date formatted in 10/20/2009 when I enter this value in the web form under my account "Hire Date". I also checked the display options in the preferences of planning. If anyone knows if this function works even on 9.3 or 11.1?

  Hello

  Looks like you have not defined the order of evaluation of Auditors. Administration > Dimensions > evaluation order > select plan type > moving accounts to another window, apply.
  Try the form again.

  See you soon

• Display the data type of a column in the status bar

  Hi all

  n pl/sql developer, when I select a column in a table.

  If I clicked with the mouse on the column in the query results box, it shows me the type of data and the size of the column in the status bar

  Developer SQL does not by default,

  is there an option I can change to do the same task?

  Thank you

  No, you will need to open a popup DESC of the query to see the data types of the data returned.

• How to return the data type complex of a synchronous BPEL process

  Hi all
  I have created a synchronous BPEL process, so a partner customer link was automatically created in the project. Now the link partner of this client is to have input and output variable of type normal string where as my BPEL process finally returns a complex data type.
  In order to solve this problem, I took a processing activity and mapped the collection [variable returned by my BPEL process] to the chain of production of the customer but in this way I just get a single string to store the entire collection but I want that they separately.
  
  Can someone tell me, how to manage this scenario.
  
  Concerning
  Lokesh

  After creating the partner link and the invoke (to create the variables), change the element type of the response message to the complex type definition of your collection that appears in the XSD. You can do the same thing if you want to change the element type of the payload of the request message as well.
