• Anonymous - SELECT user FROM DUAL;

  I am filling a field in table LAST_UPDATED_BY VARCHAR (15) a form of APEX, with the following valid trigger:

  The field is filled in with the value: ANONYMOUS after clicking on the button changes to. Can someone tell me why?

  ANONYMOUS is the real database user...

  Try:

  Therefore not select necessary...

• SELECT * FROM DUAL-> Can this statement to make the quick health check?

  We have a product that will "SELECT * FROM DUAL" every 5 minutes. If there is no response, it sends an incident.
  
  My question is:-
  
  DUAL is a magic table in Oracle. So, without access to an actual table in oracle, can we take out of this statement
  before report us any problem on a database? In other words, this statement could be successful, but what are the chances
  that a query on a real table can fail due to limited resources?
  
  Thank you

• Why a function in a SELECT FROM DUAL is faster?

  (1) I have a SELECT with a function. Ex:
  "SELECT DISTINCT function (...) TABLE.
  
  (2) I've changed to SELECT it and to put the function inside a subselect with FROM DUAL. Ex:
  "SELECT DISTINCT (SELECT function (...) Table (FROM DUAL).
  
  (3) the second SELECTION is faster than the first.
  
  I discovered this problem on my paintings and my duties. I therefore made a generic example for this forum with a common function and large table. My results:
  Table has 2.196.058 records and the field is a VARCHAR2:
  SELECT DISTINCT SUBSTR(field, 2) FROM Table-> Executed in 110 seconds
  SELECT DISTINCT (SELECT SUBSTR(field, 2) FROM DUAL) FROM Table-> Executed in 39 seconds
  
  Why «SELECT DISTINCT (SELECT function (...)» Table (FROM DUAL) "is faster than «SELECT DISTINCT function (...)» TABLE.
  
  
  Thank you
  
  Fernando

  Dang, forum software is buggy course today

  I'm sorry, I'm more confused!

  Oops, now we don't want that to happen!

  OK, back to the original question: "why call a function of a scalar subquery faster?
  Answer: because the function can come from the cache and reused instead of the function running again.

  I found this explanation step by step, which should make it clear (and it has substantially the same as what I had in mind to put in place as a test of the case later tonight), take a few minutes to read this one as well:

  http://www.oratechinfo.co.UK/scalar_subqueries.html

  When you compare the unit tests for your own testcase, it is clear that:
  -using the fractions of a second to test the scalar subquery caching will give you many different results.
  -all your table column values are distinct
  Oracle knows that it is not possible to reuse a result of cache here function, given that all the results will vary and so it will re - run your function in your query for each record in your table, no caching of scalar subquery cannot be expelled.

  Hopefully this will clear your doubts for good now ;)

  About step 7 and 8: No 11.2 for me available (yet), so I can't say anything about this, sorry about that.

  Edit

  In addition, one of your previous answers was:

  When I use a function within the SELECTION, I have a SCALAR subquery caching.

  Now, this is not 100% true.
  Depends (as always), you can have it, you will not, depends on the data allowing Oracle to reuse the results of the function of cache.

• Selected values from Shuttle

  I know there is a lot of discussion on the values of the shuttle and how to get the data to display on the right side, based on calculations. That makes sense, and I have this job.

  Jon

  Hi John,.

  If I read you correctly, you have, say, an element of shuttle based on "SELECT ENAME, EMPNO FROM EMP r BY 1 D". The value of must be based on a string delimited by two points values EMPNO and you don't have these values available on any table? But these documents are available in the P251_NAME article?

  If so, the only thing you need is to make sure that this string of P251_NAME of the EMPNO values delimited by a colon.

  Is this good? If not, could you explain more (perhaps using the select above as a guide)

• Use of bluetooth, how to copy selected music from my Macbook 2009 to my new iMac

  Using bluetooth, how can I copy selected songs from iTunes in my old Macbook to my new iMac? (It might help us to let you know that I don't buy music from the iTunes store). Thanks in advance for your advice.

  How old is the MacBook? Support AirDrop?  If this isn't the case, then the simplest method would be to use a flash drive to move audio files selected from the MacBook to the iMac.

• Impossible to delete previously selected items from the drop-down lists at the click of the button Reset on a page of the screen.

  Hello

  I'm unable to clear previously selected items from the drop-down lists at the click of the button Reset on a page of the screen. The code I did to clear the previous value when the click on the button Reset is as below.

  {} public void onReinitialize (ActionEvent actionEvent)

  System.out.println ("onReinitialize is called ::");

  UIComponent uiComp = actionEvent.getComponent ();

  If (uiComp is nothing)

  {

  otherwise we use the button that we linked to that bean

  uiComp = getButtonResetByBean ();

  _logger.info ("reset fields: buttonID =" + uiComp.getId ());

  }

  on the other

  {

  _logger.info ("reset fields: CompID =" + uiComp.getId ());

  }

  Pass the component inside the uniforms, UIXForm, UIXSubform, UIXRegion, UIXPopup, RichCarousel

  or RichPanelCollection that contains the components to reset

  getTextIDLOV () .setValue (null);

  ResetUtils.reset (uiComp);

  }

  Using this code Iam able to clear the entrance to the text box but can not clear previously selected items from the drop-down lists when the reset button is clicked

  Hello

  This sounds like a job for the analytical SUM function.

  As you post CREATE TABLE and INSERT statements for your data, I will illustrate using the table scott.emp, which is probably on your system.

  Scott.EMP contains the ename, hiredate and sal columns below:

  ENAME HIREDATE RUNNING_TOTAL SAL

  ---------- ----------- ---------- -------------

  SMITH, 17 December 1980 800 800

  ALLEN 20 February 1981-1600-2400

  February 22, 1981 DISTRICT 1250 3650

  JONES, 2 April 1981 2975 6625

  May 1, 1981 BLAKE 2850 9475

  CLARK 9 June 1981 2450 11925

  13425 1500 08 - Sep - 1981 TURNER

  MARTIN 28-Sep-1981 1250 14675

  5000 17 November 1981 KING 19675

  JAMES 3 December 1981 950 23625

  FORD 3000 3 December 1981 23625

  MILLER, January 23, 1982 1300 24925

  SCOTT on April 19, 1987 3000 27925

  ADAMS, 23 May 1987 1100 29025

  Now, let's say, we want to show that the first lines (in order by hiredate) where the total sal is not more than 10000.  One way to do that would be to use the SUM function to calculate the running_total above column and use running_total in a WHERE clause, the results below:

  ENAME SAL HIREDATE

  ---------- ----------- ----------

  SMITH, 17 December 1980 800

  ALLEN 20 February 1981 1600

  DISTRICT 1250 22 February 1981

  JONES, 2 April 1981 2975

  May 1, 1981 BLAKE 2850

  Here's a way to do it:

  WITH got_running_total AS

  (

  SELECT ename, hiredate, sal

  SUM (sal) over (ORDER BY hiredate) AS running_total

  FROM scott.emp

  )

  SELECT ename, hiredate, sal

  OF got_running_total

  WHERE running_total<=>

  ORDER BY hiredate

  ;

  The subquery is necessary because the analytic functions are calculated after the WHERE clause has been applied.  If we want to use the results of an analytic function in a WHERE clause, you must calculate the function in a subquery (as got_running_total, above).

• Right-click DeptEmp.jsf and select run from the context menu

  Hello
  
  Please consider article Oracle Magazine "Catch Me If You Can ' Frank Nimphius

  In the article, it is offered several times to
  «... Right-click DeptEmp.jsf and select run from the context menu...'.»
  When you use JDeveloper 11.1.2.3.0 it will result in JDeveloper starting a browser requesting a URL "/ faces/DeptEmp" (without ".jsf").
  (Note that in the sample adfc - config.xml has a view with the id "DeptEmp" activity, but for pages without an activity view corresponding to the stream of unrelated task (adfc-config.) (Xml) JDeveloper starts a browser requesting a "/ faces/otherPage.jsf" URL (with ".jsf").)
  
  Still, I wonder if we should really run (JSF) pages, or rather an activity view in the flow of a task?
  
  After running into issues with calling (JSF) page URL rather than controller unbounded ADF task flows view activity URL in another forum thread [1], I try to avoid pages (JSF) (execution of the task-flow unlimited instead) running.

  Hello

  Still, I wonder if we should really run (JSF) pages, or rather an activity view in the flow of a task?

  The recommendation is to run the activity. I think it's just my laziness to boot from the JSF file in the case of the article (and given my article only has a single page in the workflow unlimited I wonder if my attempt failed, if there was a need for a navigation to another view in the flow of unlimited work). The risk from a page directly, it is a physical implementation of a view that could be used by multiple streams of different tasks (although the common use of the stubborn workflow is to go with fragments of the page, always bounded task flows could be defined using complete documents). His recommendation that you start an activity to view pages in order to ensure the ADFc is used (I wasn't even not aware of 11.2.3 to automatically change request activity instead of the file if there is an activity of referencing).
