  Your question is answered in the Performance Tuning Guide

  Using indexes and clusters

  14.1.4 choosing composite indexes

  A composite index contains several key columns. Composite indexes can provide additional benefits compared to the index to single column:

  • Improved selectivity

    Sometimes the two or more columns or expressions, each with a low selectivity can be combined to form a composite with a high selectivity.

  • Reduced IO

    If all columns selected by a query are a composite index, then Oracle may return these values in the index without access to the table.

  A SQL statement can use a path on a composite index if the statement contains constructions that use a main part of the index.

  Note:

  This is no longer the case with the skip index scans. See "Index Skip Scans".

  A main part of an index is a set of one or more columns that have been specified first and consecutively in the list of columns in the CREATE INDEX statement that created the index.

• When you create a program to install the application in BT, which driver or the runtime must be installed to install the interactive control of VISA?

  I have created an installer requires the use of the LabVIEW application builder and use it to install NI MAX.  However, after you run the Setup program, interactive control of the VISA is disabled in NI MAX.

  The installation program installs the following components of NEITHER: NI LabVIEW Run-Time 2014 SP-1(64-bit) NI LabWindows/CVI shared Run-Time Engine 2013 SP2, OR Measurement & Automation Explorer 14.5, NOR-488. 2 application Development Support (including the time of execution), - VISA Support Configuration 14.0.1, OR - VISA DURATION 14.0.1, 14.0 Server NI-VISA, NOR systems Configuration Runtime 14.5.0, vision performance, performance dc power.

  If I download and run the installer 488.2, interactive control of the VISA is activated in NI MAX.  But the Setup program created with the application builder does not seem to install the necessary components.

  What needs to be added to the installer to allow the interactive control of VISA (VISAIC)?

  Thank you.

  I neglected to include OR-IMAQdx in Setup, which explains why NEITHER MAX was not to recognize the camera on the computer with the new facility.

• Is it possible CreateInsert with the value of the attribute of a backingBean method?

  Hello, I am using JDeveloper 11.1.2.3.0
  I want to create a new record in the database with an attribute in a backingBean method. I have therefore a method that returns a string and I want to use this value for one of the attributes when I fill out the form in the ADF. But I have a problem because the operation CreateInsert cleans all the fields of the form. Is it possible to only fill the other fields of the form and as a field to be filled in automatically with the value returned by the method? If this isn't the case, please give me an idea on how to achieve this.
  Thank you

  Ok

  For example, if you have a button to your form to create a new line.
  The button should be as below:

  And the code in your backing bean:

  public String onCreateRowClick() {
    OperationBinding op = getBindings().getOperationBinding("CreateInsert");
    Object result = op.execute();
    DCIteratorBinding yourIt= getBindings().findIteratorBinding("yourViewIterator");
    Row newRow = yourIt.getCurrentRow();
    newRow.setAttribute("aa", getAttributeValue());
    return null;
  }
  
  public DCBindingContainer getBindings() {
      DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
      return bindings;
  }
  

  and of course, you should have the "CreateInsert" action in your page links.

  Do you need anything else?

• Control the order in which the tools are displayed

  Hello

  I have developed a number of folder level JavaScripts.  Each JavaScript displays a button to launch under the "additional tools".

  I was hoping that someone could tell me how I can control the order in which these buttons will be displayed.

  Buttons are displayed in alphabetical order according to the 'cLabel '?  If they are listed according to the date and time the file was created or modified?

  Is there an optional parameter to set the order?

  Thank you

  Linda

  Hello

  Actually, I figured out how to control the order in which appear the buttons below "additional tools".

  There is an optional parameter for app.addToolButton called NPO: which can be used.  I think that the lower the number used, the highest on the list, the button will appear.  This kind of work.  The list of buttons re - arrange themselves, but not exactly the way I wanted to.

  Another thing I did was to rename the JavaScript files. I went before the first file name with a '1 '.   The second file directly under the first I preceded it's name with a number '2' and so on.  That seemed to do the trick...

  All I had to do was probably to rename the JS files with the '1' and '13' numbers and buttons with appear correctly.

  Thank you

  As Pascal said, the two components will be installed by the same installer (fixes 2 group).
  So you will need to have the database, create diagrams with the ruc, install the weblogic server and install soa suite patchsets

  When you start to create the areas you will see you can both allow the soasuite and bpm components

• When downloading music from Media Player on a USB key, how to get music aired in the order I put them on the list of synchronization?

  I find that when I play the USB in my car stereo, all the parts play in the order in which I originally recorded my media player CD.  I drag synchronize them in the order that I want but they play seemingly at random, but I think it might be chronilogical order of their recording in Media Player.

  Hello Warner,

  The best way I found to do this is to create folders on the USB drive and then use a different folder for each album of the music.
  If you want music in a particular order, change the name of the file to include a 001 at the beginning, for example, 001 - songname.mp3 music
  Do this for all the tracks in the order you want and software of the car detects the number and play music in that order.
  I hope this helps.

• Validation on the value entered for the attribute-based LOV

  Hello

  I use R12 and created an integrator based on a Table based on a table of seedlings open interface. I use an approach that does not involve PLSQL since the Integrator is based on a Table on a table of seedlings open interface and I have so defined it an importer to call a simultaneous program seeded import. I also put in place a LOV component on one of the attributes in the interface.

  My question is, if in the spreadsheet, the user double-click in the cell LOV to extract, and then select a value (for example if they are in copying and pasting quite a few records if they manually type a value) and the value you entered don't is not one who belongs to a group of data from the LOV, this would raise a validation error when loading?

  In this scenario, I would LOV to serve as a validation check to ensure that users can choose only one value that would be in the LOV, even if they have not actually open the popup LOV and selected a value there. I have some research which I would probably need to validate the data against and because my approach is purely a non-PLSQL that I think the best way to achieve this.

  Appreciate your help as always

  Concerning

  Not to worry, I think I answered my own question by developing a little proof of concept.

  As expected, you can enter values that are part of the DataSet LOV. Enter any other value will highlight the line as an error line asking the user to enter a valid value.

• How to display prices with which we won the most?

  Hello guys!

  I try to learn a few new skills in oracle sql if I was looking for examples on the web. I found this one, with 6 questions. I did all the tables and all the connections. I knew solve 5 questions but that, finally one seems too difficult for me.

  I don't know how to display tables with which we won the most. We do need to check what Denis is rendered which course and anyone who paid that invoice, what kind of prices was also on this Bill (normal od student).

  I would be really happy if you guys could help me.

  Thank you very much!

  If you don't understand anything, despite my bad English or anythning else, feel free to ask. I would be really happy if we could solve this problem!

  As far as I know, bill and section have no impact on this problem.  As Frank said, this looks like a Top - N type problem.  You is a way to get answer:

  dev1 > select gains, num_students, lesson_name, course_name

  2 from (select course_name, lesson_name, num_students, gains,

  3 dense_rank() ON rn (salary desc order)

  4 of (select c.name course_name, l.lesson_name,)

  5 count (vr.id) num_students,

  6 sum recipes (p.price)

  7 of course c

  8 Join Conference l

  9 l.fk_course = c.id

  Join the 10 visit vg

  11 on l.id = vg.fk_lecture

  join 12 visitor RV

  13 on vg.fk_visitor = vr.id

  price of 14 p join

  15 p.fk_course = c.id

  Group 16 by c.name, l.lesson_name))

  where the 17 rn = 1;

  LESSON_NAME NUM_STUDENTS PROFIT COURSE_NAME

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

  C++, programming 3 750 programming

  Java programming programming 3 750

  If you really don't want that one line returned with a tie, then you replace dense_rank, row_number or do something like:

  Select course_name, lesson_name, num_students, recipes

  from (select c.name course_name, l.lesson_name,)

  Count (VR.ID) num_students,

  Sum revenue (p.Price)

  of course c

  join the l Conference

  on l.fk_course = c.id

  Join visit vg

  on vg.fk_lecture = l.id

  Join the vr visitor

  On vg.fk_visitor = vr.id

  Join the price p

  on p.fk_course = c.id

  C.name group, l.lesson_name

  order by 4 desc)

  where rownum = 1;

  This structure returns a single line in the case of links, but there is no way to predict which of the related rows will be returned.
