• What's the point of having several columns in the ORDER BY clause?

  DB version: 10 gr 2
  
  When you use the ORDER BY clause, the lines are always sorted by the first column in the ORDER BY clause. So, what's the point of having several columns in the ORDER BY clause (I always see this in production codes)?

  When in the second query, I sorted out only for age, you saw it there two 26 years old Keita, there was first Agayev, then Taghiyev. But if I want to get the family names in descending order when there are two very old person, then I will add the second column in the order by clause

• What is the point of the current program of recovery iPhone?

  I just got the latest offering from resumption of Apple advertising up to €475 off a new iPhone and frankly think it's an absolute and misleading marketing effluent pot... I can sell my current for more iPhone double Apple are rewarding it and wonder what's the point?

  Come on Apple... It's false, at least give us the same jumps that you give the operators?

  You forget something important here: Apple offers up to 475 Euros. Each phone is evaluated by Apple, and then the price is established.

• What is the point of groups on bike g

  Hi all, I am new to android this is my first ever smart phone and also of new forums etc, so please be gentle with me. And sorry if this is in the wrong section/place?

  For the last two days, I searched for an app (free of course) which will help me to multi/Group text and messaging multi/group.

  I love my motorcycle G 2nd gen, but these missing tools, contact base are a real let down for me because I need and what I understand, have to manually enter the details to say around time of 20 contacts each wished to text or e-mail, is a good PITA bread, and not always with success.

  This should have been included even on stock android sytems. Even my old Samsung E2600 offered these features!

  Anyway, I've created a group of my 'People' file and cannot do something with it, so what's the point of 'grouping '?

  BTW, I told you that I love my bike and two of my friends came out and I bought one after playing with mine.

  There is an application called 'Contact group' which will give this feature for you. I've used this in the past and it seems to work pretty well. There are other applications like 'DW Contacts and Dialer' which will also give you these features, but you don't have to abandon your application of those default to get the features using this application.

  I'm sure that there are other applications available, but these two are the ones I've personally used and I am prepared to recommend. I hope this helps.

• What is the point of this program?

  I just installed it, began to watch the tutorials on it and then work with her to know that it is basically useless in the end.

  I followed the other threads here that State that it doesn't sort capabilities to export your work so that you can develop.

  It's misleading because the exported page.html and boilberplate.css even for something as simple as a layout with 2 breakpoints and only 4 empty div is very imperfect.

  Basically, the exported html and css are not working and I still show the 1620px and the breaking point, even if my screen is 1920px.

  To go back and fix the flawed css makes the process of any model useless.

  I'm missing something here... What is the point of this program?

  So far all I can do is create useless templates which can not go further.

  My attachments show what I see inside reflow and what do I get when I open page.html.

  

  I think it is just a demonstration for MAX 2013.

  I played with this for over a year, but there is no update to fix major bugs or requested features.

  Do you already have a scenario where a numeric column should store only values with a fixed precision and scale?

  Plenty of needs of the company for specific details and scales.

  An age can the persons required to be stored as whole not more 3-digit numbers.
  A sum of money may have to be stored with no more than 2 decimal places of accuracy for example the books of GB Pence or US Dollars and Cents
  A unit of length may need to be stored in meters with 2 decimals of centimetres
  A size may have to be stored with a decimal for half sizes
  etc.
  etc.

  Yes, you can create simply as a generic NUMBER data type, but their design with precision and scale can provide additional information on the limitations for the stored values, especially for things like tools that can use the specified precision and scale to determine how to display the automatically (default) values of reporting.

  If you start to question "what is the point?" then you may as well say what's the point of having a NUMBER data type when we can store numbers in a VARCHAR2 data type? or what's the point of having a DATE data type, when we can stored dates as VARCHAR2 data type? etc.

  No need to ask such a question because there is almost always a point to these things (and if not what they get deprecated in future versions).

• What is the point of type conversion of forms, rather than just flattening at required resolution?

  OK, this may seem a stupid question. Lets say that I see a three-pronged in Photoshop. The printer asks that the drawings are conducted on a 300 dpi resolution.

  What is the point in the conversion of any type of forms before the registration or embed fonts when I can flatten just my design at 300 dpi as a whole? Don't go printing do anyway... flatten just my design? Or they print type at a resolution higher than the portions of the frame of the drawing or model? He mistook me for too long. I hope someone can clarify this. Thank you

  300 ppi measurement is used for the midtones (aka filtered) images. Text is often not tracked so this resolution does not apply. You want a higher resolution (obtained by keeping the text in vector format) to keep a clear text.

  When sending art to a printer or to the bottom of the page-assembly line, it is ideal to save in PDF format that it will retain the direct type of Photoshop as a material of vector fonts.

• What is the point of having the function of the cloning in custom events?

  What is the point of having the function of the cloning in custom events? I do this, but never understood why lol

  The EventDispatcher call to clone the event when you return an event with dispatchEvent (event). It is also why you should implement it correctly (copy all properties), otherwise the listeners who handle the redispatched event will receive an event with incorrect values.

• What is the difference between making a site inactive and end provider, provider dating site?

  Hello

  There are 3 ways to make a provider site unavailable for use in R12?

  Accounts payable Manager > search provider, and then click address book

  (1) click the button remove

  2) click on "Update" and change the status to "inactive."

  3) click on 'Manage the Sites' and fixed the date passed in 'inactive Date '.

  What is the difference between them and what are the advantages and disadvantages of each.

  Kind regards

  Mindy

  Pros to delete: If there were human errors while accessing a supplier Site and if they are to be discarded then you can use this option. By example, bad provider Siite imported sources via interfaces or data conversion.

  Cons to delete: Auditors will be unhappy because the record is no more.

  Pros from inactive: Consider a scenario in which a provider of on-site audit has arrived and the audit found non-compliance with the operations of the Site to a specific provider. In such a case, that your company has decided to not not to create one more (or business) transactions with the Site Supplier up to what the provider meets the policies agreed contractual and accounts gives a green signal. And this is where you use 'inactive' for simply inactivate the vendor Site and then reactivate after passing a second check.

  Cons of idle: You not save the date to which it has been inactivated. However the database captures the "last_update_date" column (which is not useful unless you have activated the check feature).

  Pros inactive Date: Consider a scenario in which your provider had a warehouse in Auckland. But now they have closed the warehouse and moved to China. In this case, you always want to maintain previous transactions in the system, as well as from the point of view of the audit after inactivating you add some comments here. This is where the functionality of 'inactive date' will be very convenient in which you show clearly in the system when the site became inactive (and the reason for this action).

  I hope this helps.
