Difference between INSERT and EXTEND in OBPM Arrays

Hi all,
I wanted to know the diference between the EXTEND keyword and INSERT keyword while using OBPM arrays.
For e.g. if testArray is an Array then:-
What does testArray.insert mean?
And
What does testArray.extend mean?

Extend inserts at the end of the array. Insert allows you to specify an index into the array where you want to insert to.

Difference between implements and extends

Hi all,
what is the difference between implements and extends. i am sorry to ask this silly question, but i am new to JAVA.
Thanks
Balaji

when you extend a class, your class that you are coding inherits every method and field from the extending class. For example:
public class CustomFrame extends JFrame {
//Your class's methods will be in here, but so will all of JFrame's methods.
}You can override (most) methods from extended classes if you want them to do different things than they normally do. The most commonly overriden methods when using swing are stuff like paint(Graphics g). It needs to be overriden to repaint all of the components.
When you imlpement something, you have to specify an interface. Interfaces have methods in them with no code. If you implement an interface, all methods in in must be defined. If not, the code will not compile. Some interfaces like ActionListener extend other classes to perform stuff. The actionPerformed(ActionEvent e) method will perform an action when a button is pressed, etc.

Difference between Implement and Extend

what is the difference between implements and extends and why do we use them
thanks,

classes extend one other class and implement as many
interfaces as they wish.
interfaces extend as many interfaces as they wish.But for all that, they both just mean "inherits."
There wouldn't even have to be two different words, since you never have a choice between X extends Y and X implements Y. For a given X and Y, only one of the two will be legal.

Difference between Insert and Insert all

Hi,
I tried to understand what INSERT ALL syntax is doing, but I cannot find any difference between INSERT and INSERT ALL.
I replicated the test scenario using the data from the below mentioned URL:
http://psoug.org/reference/insert.html
I also did a google on finding up the difference between them, but could not find any...
Please advice if both are same as I have planned to use INSERT statement with a WHEN clause if INSERT ALL is same as INSERT.
Thanks!

Hello
The key difference is that INSERT ALL will allow you to insert into multiple different tables in a single statement whereas INSERT will only insert into 1 table. Each of the WHEN clauses allows a different table to be specified.

Whats the difference between implements and extends!??

Can an interface be extended or not??
If it can whats the difference between implements and extends??
Thank you!

Code Sample:
interface a implements aa{This is illegal. An interface cannot implement another interface. It can only extend another interface.
interface a extends aa{That's the way to do it. As already said above:
An interface can only extend another interface.
A class can extend another class.
A class can implement zero or more interfaces.
So, "implements" is only used for classes that implement interfaces. For the rest, "extends" is used.

Help me clarify: Difference between Joining and Extending Wireless Network

I've eventually figured out how to get my AirPort Express to allow my Mac Pro access to the internet Via Ethernet cable by joining an existing wireless network. What's the difference between that and extending it? By extending it I loose my ability to use the ethernet to connect to internet on my Mac Pro. Odd thing is though when I initially used AirPort Utility to set up my AirPort Express, I went through all the options to get it configured to access my existing network and I checked option to allow internet access through ethernet. All is well, but then I still don't have access to the internet through the ethernet and I noticed that the setting is on Extended. Just curious why it would give me the option to use the ethernet, set it on extended and not even work.

I've eventually figured out how to get my AirPort Express to allow my Mac Pro access to the internet Via Ethernet cable by joining an existing wireless network. What's the difference between that and extending it?
When "joining a network," the AirPort Express Base Station (AX) acts just like any other wireless client (laptop, desktop, printer, etc.) You would want to configure the AX to join a network when you only want to use it to share a USB printer and/or stream iTunes.
When "extending a network," the AX can perform as either a main, relay, or remote base station in a Wireless Distribution System (WDS). A WDS is primarily used to extend a network wirelessly.
By extending it I loose my ability to use the ethernet to connect to internet on my Mac Pro.
If the AX is configured as either a relay/remote base station in a WDS, you actually can use it's Ethernet port for Internet access. Of course, this relay/remote must be connected to a main base station, that itself, has Internet access.

What is the difference between Classic and Extended Withholding Tax

Hi,
Can some please tell me what is the difference between Classic Withholding and Extended Withholding Tax. How can I look at the Withholding Tax deducted from a particular invoice?
Number Guaranteed.
Thanks.

Dear Prem,
Withholding tax is the basically a tax withheld during the Vendor payment. So when making the payment to vendor the amount will be deduct (i.e withheld tax)
from the invoice and paid. The customer is actually the tax to tax authorities.
you can visit for more info.
Withholding Tax
For the config steps you go to the IMG path FI > Financila accounting for the Global settings > Withholding Tax
Withholding tax configuration is done by FI person.
Hope this helps you

What is the difference between WDS and Extending a network?

What is the difference between the two? Why choose one over the other?

Both the WDS and "Extend a wireless network setting will add more coverage area to a wireless network.
WDS must be used if any device on the network is an older "g" device. The downsides to WDS are that it drops the overall wireless speed down to "g" levels (even if there are other newer "n" routers on the network) and cuts the bandwidth capability of the network in half for each "remote" device that is added to the network. That's a really severe loss in performance.
"Extend a wireless network" is a newer technology that can be used only if all of the routers on the network are newer "n" capable devices. It allows full "n" speeds and imposes only a small bandwidth penalty on the network. Obviously, this is the setup to use if your devices will support the technology.

Difference between "joining" and "extending"

Just added an airport express to my time capsule network. I realise that if I use the AEx to "extend" my network then the time capsule is relegated to 802.11b/g and not n.
Is the same true if I just "join" the AEx to the network and use it for iTunes and remote speakers?
Barry

Just added an airport express to my time capsule network. I realise that if I use the AEx to "extend" my network then the time capsule is relegated to 802.11b/g and not n.
Good news! That is not true. 802.11n offers the "extend" feature only between 802.11m base stations.
If you use WDS you get the same functionality but you are forced to 802.11g.
Is the same true if I just "join" the AEx to the network and use it for iTunes and remote speakers?
When the AirPort Express (AX) is configured to join a wireless network it simply acts as just another wireless client. Therefore if the network is using 802.11n the AX will communicate using 802.11n.

What's the difference between WDS and Extend Wireless Network?

Hi,
I have a situation where my main computer (Mac Pro) is wired to an Extreme (n), and I have an Express (n) in another room in the house to Bridge to other computers for better wireless reception.
The manuals say I should be connecting the wireless computer via WDS. The way I have it connected right now is as such.
Extreme:
Create a wireless network
Allow this network to be extended is checked
Express:
Extend a wireless network
Allow wireless clients is checked
Is the above method correct, or should I be setting the Extreme and Express via: Participate in a WDS network?
Any help would be appreciated.
Thanks!

I am not an expert on wireless networks but here is what they do in a nut shell:
WDS is a network composed by access points that work together to expand your network without the need of "wired" connectivity. so one of the bases will be wired, the rest are not , they just relay info to other computers... good for small to medium size business / homes
EWN is a network composed of wired & wireless networks/access points that work together to expand your network. pretty much you could have 5+ bases plugged in to a LAN / WAN covering different areas of your company / home (long range for medium / big business / Bill Gate's home, etc.).

HT1604 Is there any difference between Mac OS Extended Format and ExFat?

Is there any difference between Mac OS Extended Format and ExFat? I read in a blog that the ExFat was a good way to format an external drive because it avoided many of the pitfalls of the other formats, as long as it is supported by the operating system. I tried to format my new Seagate drive, and got an invalid option error. I was able to format it in Mac OS Extended format. Can you please tell me if this is similar to ExFat. Thanks.

The Mac OS format can only be natively read to and written to by a computer running the Mac OS. This creates a problem if the user wishes his external, or other drive to have seamless compatibility between two different OS's, such as Windows and Mac. Yes, there are software solutions that enable a Windows PC to work with a drive formatted as Mac OS, but it gets complicated if you wish that drive to have compatibility "on the fly" with any PC you may encounter.
It turns out that the format known as ExFAT is able to be natively read by both a Mac and a PC, without running any additional drivers on either machine. ExFAT also doesn't have some of the limitations of FAT32, which both OS's will also read/write.
ExFAt is not perfect though. Formatting the drive as Mac OS Extended has some advantages on a Mac. First, it is the only format that permits all functionality of the Mac OS, such as using the drive for Time Machine.
ExFAt is often thought of as the best middleground for an external partition/drive that needs to have easy cross platform compatibility between a Mac and PC running Vista or Windows 7.

6 rows selected.Both inserting insert the same records then whats the difference between ALL and FIRST clause in multi insert DML
Khurram Siddiqui
[email protected]

Hello
From the docs:
ALL
If you specify ALL, then Oracle evaluates each WHEN clause regardless of the results of the evaluation of any other WHEN clause. For each WHEN clause whose condition evaluates to true, Oracle executes the corresponding INTO clause list.
FIRST
If you specify FIRST, then Oracle evaluates each WHEN clause in the order in which it appears in the statement. For the first WHEN clause that evaluates to true, Oracle executes the corresponding INTO clause and skips subsequent WHEN clauses for the given row.
ELSE clause
For a given row, if no WHEN clause evaluates to true:
* If you have specified an ELSE clause, then Oracle executes the INTO clause list associated with the ELSE clause.
* If you did not specify an else clause, then Oracle takes no action for that row.
See Also:
"Multitable Inserts: Examples"
Restrictions on Multitable Inserts
* You can perform multitable inserts only on tables, not on views or materialized views.
* You cannot perform a multitable insert into a remote table.
* You cannot specify a table collection expression when performing a multitable insert.
* In a multitable insert, all of the insert_into_clauses cannot combine to specify more than 999 target columns.
* Multitable inserts are not parallelized in a Real Application Clusters environment, or if any target table is index organized, or if any target table has a bitmap index defined on it.
* Plan stability is not supported for multitable insert statements.
* The subquery of the multitable insert statement cannot use a sequence.

What si the difference between crete and create insert operations.

Hi
In ADF 11g,what is the difference between create and createinsert operations.
if anyone knows plz tell me.Any document about this plz provide me.
Any help is appreciated.
Sailaja.

Hi,
CreateInsert: Creates a new row that becomes the current row, and inserts the
new blank row into the data source.
Create: Creates a new row that becomes the current row, but does not insert it.
--> normaly you would use createinsert
Doc you can find here (search for Createinsert): http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974.pdf

Whats the Difference between Wrapping and Inserting a subform?

Pardon me for asking what is probably a silly question. But what is the difference between wrapping and inserting a subform? Thank you very much in advance.

-When you insert a subform, a new subform that does not contain any form objects at the time of creation is added.
-When you have existing form objects that you decide at a later time in your designing process to be contained in a subform, you can wrap these existing form objects by a subform.
