• Any difference between the separate function and aggregation in sql query cost?

  Hello
  I've run many models sql stmts - such as:
  one) using a single table
  (b) using the two tables, using simple joins or outer joins
  
  but I didn't notice a difference in sql stmts in cost and implementation plan...
  In any case, my colleague insists on only using the aggregate function is less expensive compared to
  separate... (something I've not confirmed, that is why I believe that they are exactly the same...)
  
  For the situation described above under 1 sql... We could for example use
  

  select distinct deptno
  
   from emp

  select count(*), deptno
  
   from emp
  
   group by deptno

  select distinct owner, object_type from all_objects

  select count(*), owner, object_type from all_objects
  
  group by owner, object_type

  Have you ever found no difference between the two...?
  
  Note: I use Ora DB 10g v2.
  
  Thank you

  Alexandre Gelin says:
  function separate and aggregation are for different uses and can give the same result, but if you use the aggregate function to get the separate records, it will be expensive...

  really? I find them almost identical to 11g. Actually GROUP BY is almost always more fast for me in the old days.

  What is the difference between the Service Station and Tempro?

  I just run the wizard upgrade Toshiba and it installed the gas station but Tempro is already installed and seems to do the same.

  Hello

  These two tools are Toshiba one informs you of the new driver updates available on the Toshiba driver page.

  AFAIK Tempro is slightly older than the gas station.
  In addition the gas station seems to provide a bit more options and features like tool Tempro.
  However, I recommend using one my favorite utility's Service Station

• What is the difference between the HX - 90v and HX - 80 coming cameras?

  What is the difference between the HX - 90v and HX - 80 coming cameras?

  Thank you!

  I'd say it's supposed to be a fill, a little brother to the HX90v

  It removes the control ring and the GPS, and I think the rest is the same.

  It is for those who want the HX90v but the price is a bit steep for the compact range, and they need not necessarily GPS or the ring of command, just a camera that works.
  This kind of thing, at least to my knowledge.

• What is the difference between the "Software Version" and "Version of the platform?

  I posted in this forum, because there is a maximum activity in this forum. Sorry, if this is not a good place to post this kind of question.

  What is the difference between the "Software Version" and "Version of the platform" of any blackberry device?

  My camera's curve 8900 and I can see in the menu About his version of software is 4.6.1.231 and the version of the platform is 4.2.0.108. What are these 2 versions for?

  Probably the best posted in the software section of the device, but is not serious.

  Version of the software/App - indicates the version of your applications (address book, browser, calendar, etc.).
  Version of the platform - indicates your version of system software (Java based software, radio code, etc.).

• What is the difference between the substituted glyphs and substituted fonts?

  Hi all

  Someone could tell you what is the difference between the substituted glyphs and fonts substituted in the Panel preference.

  Thank you

  Kasi

  1. In InDesign, the word police refers to typography and style: you might miss Helvetica or, for example, Helvetica Bold.
  2. A glyph is a particular form of a character in a font: for example, the letter H can be available as a standard H or a signature H or ornament. If the police does not have the signature or ornament glyphs, which would produce the missing message of glyph.

• What is the difference between the time cpu and cpu in AWR db?

  Hi, experts:

  What is the difference between the time cpu and cpu in AWR db?

  As a general rule, 'DC CPU', 'CPU Time' (and 'DB CPU of "TIME") are references to the same (i.e., a measure of the amount of time the instance of Oracle on the CPU), but to avoid any risk of misunderstanding, it is best to give us a little background labels - i.e. lines 6 or 7 containing an example of every use of one of your AWR reports

• What the difference between the $29.00 and $1 099 in terms of features?

  I want to buy the software but I m so uncertain ante Adobe phones DO NOT work properly... What the difference between the $29.00 and $1 099 in terms of features?

  There is no real difference at all, it is the same app, same features.

  The $ 29 subscription means that you 'Rent' the application, you will have all the upgrades and patches during your free subscription. You can have two versions installed, but no more with this license. In addition, it is related to your personal Adobe ID.

  The perpetual license means that you have the application, it can use 'forever', and it is NOT linked to your Adobe ID when a new version appears that you will have to pay for the upgrade (if possible). You can have as many versions on your system you want with perpetual licenses. This can be important if you need to work for clients that use older versions.

  ATTENTION: I am only a user, does not not for Adobe, that's what I see as the major differences. Crossing my fingers that someone from the staff will give you more details.

• difference between the binding context and link container

  Hello experts

  can you please explain to me the difference between the binding context and link container.

  I searched on the net but unable to understand the concept.

  Hello

  the BindingContext represents the DataBindings.cpx file execution and is a record of BindingContainers and their mapping pages and views. In addition it contains information about the data used by an application controls. The link container is the representation of the execution of the file PageDef and gives you access to the collections, methods, and attributes of the data used by a page or view. Context binding is a house while the link container is a piece in.

• the difference between the intermediate process and materials first in BCP formulation?

  I do not understand the difference between the intermediate process and materials first in BCP formulation. could you give me an example to show the difference?

  The intermediate process - questions all the specifications that are used in the

  current specification.

  Raw - questioned the level of material first in the hierarchy.

  Hello Terry,

  It is used in the screen output Formulation based PCA. You can configure different PCA rule which is available in formulating exit point BOM, then when you start a screen of PCA in the base of the exit, you will see this rule.

  And the difference between the intermediate process and raw in PCA, let me explain with an example, I have a configuration hierarchy as below:

  OutputA

  A formulation

  Material X

  Output B

  Formula B

  Material M

  Material N

  If I select the output B in formulating A framework, and when I run a screen of PCA in the base of the output, I have three options:

  High level - it allows to extract A output attributes as PCA review the settings;

  Intermediate processes - it to retrieve attributes material X and B output like BCP review the settings;

  Raw - it will extract attributes of material X, output B, M and N of material material as PCA review the settings.

  I hope this helps.

  Thank you

• In EPMA: What is the difference between the dimensions time and periods?

  In EPMA: What is the difference between the dimensions time and periods?

  The time dimension, I believe only applies to the epma essbase dimensions and creates a time dimension essbase.
  The period dimension can be applied to planning, essbase, consolidation.

  So if you create an application of epma essbase and want the functionality of a time dimension, then you create a time dimension.

  See you soon
