Can you explain why the "analytical" Word is used in Sql

I found to define the "analytic function" phrase is such: "a piece of syntax that is originating excessive."
I don't understand why's called it "Analytics". In English 'analytical' comes from the word "to analyse" which means the examination of something. So it looks like "analytic function" should review/analyze something? but all the functions examaine/analyze something. If I group by article in my request, then all aggregate functions will conduct the review of the data, then why I call them better too 'analytic (al). Can you explain why the "analytical" Word is used in Sql world?

Aggregate functions will bring together data that is to sum or count etc once it is grouped together. It is not just review, but grouping.
Analytical functions review / analyze the other rows of data, without having to group them in the result that they can summarize a set of values of a particular group (partition) of the data, or they can simply retrieve values of other lines (for example lead, lag, the first_value, last_value etc. functions.) They are able to look through the data without any aggregation of it. So why they are analytical.

  • Please can someone explain why the windows Installer keeps appearing when nothing is installed? Any way to stop this?

    Why the Windows Installer keep popping up, either on a web page or an e-mail to the office when nothing is installed.  No way to stop that... ?

    The desktop of your computer, click on the tab "Start", usually located at the bottom left of the screen (on Vista, it's maybe the windows symbol instead of the word 'Start').

    Now, find and click on the program title 'run '. Vista users can locate this program by typing "run" in the area of research at the bottom of the menu 'start '.

    Once you open 'Run', type 'MSCONFIG' in the empty box and click 'OK '. This will open the System Configuration utility.

    With the open System Configuration utility, select the tab "Services".

    Scroll down the list of services (it may be advantageous to click on the 'service' column to sort the services by alphabetical order) until you find the program "Windows Installer".

    Now, click on the checkbox next to the name of the Windows Installer and click on the button 'Disable' at the bottom of the Configuration of the system.

  • Can someone explain why all my Spry assets on a website online have suddenly stopped working?

    Can someone explain why all my Spry assets on a website online have stopped responding? I checked that Spry CSS and JS files are in place. Then checked the files on Dreamweavers mode live view and they do not work here either. It was fine a few weeks ago that it's almost as if the web browsers stopped tearing Spry, for example, the links for the collapsible panels are not yet recognized as links.

    I use 'old' on Dreamweaver CS4 spry assets (if that makes a difference). Active Spry tabbed panels are removable panels.

    Thanks for your help.

    Manufacturers should come after the library. In other words, you have moved libraries below links

    
    

    Move high to the bottom of your page and everything is fine.

  • Can you be more the pair an iPhone with an iMac?

    Apple support said I should use Air Drop to share files between my iphone and my iMac (both running newer systems) in response to my request for advice as to why I could not pair them up. Seems odd to me because in the devices section on the Mac (under Bluetooth), I can see iPhone and an option to connect to the network, but I said that the network is not available. My keyboard, mouse, and trackpad all work fine so any advice would be very welcome. Or can you be more the pair?

    My pair of iPhone perfectly with my car for hands free calling.

    It has never been possible to pair an iPhone to a computer (Mac or Windows) for any purpose, with the exception of personal hotspot (internet tethering) and then only if the plan from your cell phone carrier is supported. Things like Airdrop involve Bluetooth but the devices are not matched. See below for more information: Bluetooth: why can not connect my iPhone or iPad with another iOS device or my computer?

    Hello

    I played "Mahjong Trails" and in position # 3. He played last night and I just tried a few moments ago and I come in. Can you tell why?

    I've struggled since Facebook has said that someone tried to enter in my accouant and they had me off facebook about 3 days. Who would have something to do with it?

    Impatient of solve you this problem, because I REALLY don't like this game.

    Thanks for taking care of this

    hope that I broke all the rules. and I hope that I chose the right forum because I've NEVER done this before.

    original title: GAME MAHJONG TRAILS Can t PLAY WHY

    Hello Shirley,

    This isn't a problem with MSE.  You deal with Facebook on this (as hard as I know what to do).

    There is an excellent chance that what has happened to your account either interfered with your game or was not completely fixed or there is something else wrong with your account or maybe the game.  Your best bet is to start here: http://www.facebook.com/mahjongtrails#! /help/? section = applications_and_websites and see if you can get help any with the game or the other answers predefined or by searching.  Then, would be to try general help: http://www.facebook.com/help/?topic=applications_and_websites#! /help/? tab = discussion where you can post questions about your problem.  If possible, I try to uninstall and reinstall the game (even if it make you lose your points or your rankings) - or you can ask for help from their first that they are able to help.  Or open a new facebook account in the meantime and see if you can download and play the game on this account.  So not only will you be able to play, but you will know for sure, this isn't a problem with your computer, the game, your browser or malicious software.  You can pretty well and nail down to a problem with the other account or installing the game on this account.

    It is almost certainly a problem with Facebook and not your computer, malicious software or your browser.  You need to deal with them on this subject.  If you have the best technical support coordinated because of your recent problems, by all means to re-open the case, or get help that direct contact is all but impossible here trying.

    I'm sorry, we can not help you more, but it's really a matter of Facebook and you need to deal with them to resolve the issue.

    Good luck!

    Any ideas how can I insert a pdf into word, by using the option object to insert. However, the pdf file that I want to insert text and annotated lines, but once inserted comments do not appear?  any help would be greatly appreciated.

    You will need to find a forum for MS Word, since it is the software you are trying to manipulate in the present.  If you think that the treatment/creation of the PDF file plays a role, then you should ask in the forum for the software that you use to create the PDF file.

    This forum is for a question about downloading and installing Adobe products test, so in all circumstances, your question does not fit in this forum.

  • Can you turn off the shutter sound on the factory unlocked iPhone to the Japan 7?

    Can you turn off the shutter sound on the factory unlocked iPhone to the Japan 7?

    I am going to Japan November 2016 and plan to buy unlocked (no sim) iphone to use in my country (Thailand) 7.

    However, I have read some post on 'mode of politeness' in Japanese phone but the conclusion is not clear whether you can disable shutter sound (without sim) unlocked iphone 7 or not. Then, someone could share on the current situation?

    Thank you

    No, its required by Japanese law shutter. Even if the iPhone is

    is no longer in Japan, you will not be able to turn off the shutter sound.

    You should also check with the seller to be sure you can get the

    iPhone unlocked from the Japanese wireless provider to use with your

    carrier in Thailand. And check that the iPhone is unlocked before leaving the

    retailer.
