Difference between a regular subquery and a correlated subquery

Can someone explain EXACTLY what is a correlated subquery and could you give me an example? I'm taking an Oracle DBA class and I would appreciate your feedback. Thanks. :)

"Normal" subquery (the subquery is executed only once for the statement):
select name
from emp
where salary > (select avg(emp2.salary) from emp emp2);
Correlated subquery (it is executed for each row of the main query):
select name
from emp
where salary > (select avg(salary) from emp emp2
where emp2.deptno = emp.deptno);
Can someone explain EXACTLY what is a correlated subquery and could you give me an example? I'm taking an Oracle DBA class and I would appreciate your feedback. Thanks. :)

Difference between a master DVD and a regular DVD

Can anyone explain to me the difference between a master DVD and a regular DVD. What is the workflow from FCP to compressor then DVDSP as far as bitrate settings etc? Thanks in advance!!

LOL - I wouldn't let it worry you... we all start somewhere.
When you click on 'Build and Format' you get a window appearing which lets you set all kinds of different parameters. At the bottom you will see two drop down boxes. Choose 'Hard Drive' in the top one, and '.img' in the second. This will tell DVDSP to create a disc image and put it in the location that you then specify. When done, you can double click this image and it will open like a DVD disc would - if you have got DVD Player running then your project will run as if it was on a physical disc (although slightly quicker).

Difference between Activating Master Data and Attribute Change Run

Hi
Is there any difference between Atribute change run and Activating Master data functionaaly???
if wha it is???
can any one explain clearly?
Thanks
Chinna

When u load master data and its attribute to ur data target and if u change any data or attributes of ur master data,in order to update new data to ur data target attribute change run is performed.
When u create a characteristic and if u keep it as master data and activated..it is master data activation
Activating Master Data
When you update master data from an SAP system the master data is imported in an inactive state. You must activate the new master data so that it can be accessed and used for reporting purposes.
For more information, see Versioning Master Data.
Choose the path InfoObject Tree Context Menu of Corresponding Characteristic Activate Master Data.
Upon Activation there are two scenarios to choose from:
The Corresponding Master Data Is Already Being Used in Aggregates in the InfoCube:
If you are already using the available master data in aggregates in InfoCubes, you cannot activate the master data individually. In this case, proceed as follows:
1. In the main menu, choose the path Tools Hierarchy/Attribute Change.
2. Proceed as described in System Response upon Changes to Data: Aggregate.
The system now automatically restructures and activates the master data and its aggregates.
Please note that this process can take several hours if the volume of data is relatively high. Therefore, you should simultaneously activate all of the characteristics that are affected by changes to their master data, at regular intervals.
The Corresponding Master Data Is Not Used in Aggregates:
Choose the path InfoObject Tree ® Context Menu of Corresponding Characteristic Activate.
The system now automatically activates the master data so that it can be used directly in reporting.
If there is any change r newly added records in master data..then that particular data will not b avialable for the reporting unless u do activate master data...
if u r using aggregates and then there is any change in master data ...then that particular master data change wil not b available for the reporting unless u do arrtibute change run for that info object.(T-code RSATTR)
Master data attributes and hierachies are used in cube aggregates also. So to do update the latest master data attributes values in the aggregtes attribute change run need to be performed.So Attribute change run also updates the master data attributes in aggregates which is not apart of master data activation.
Text loads do not need attribute change run. Attributes, hierarchies and aggregates need attribute/hierarchy change runs. If you do not have aggregates, just activating the master data is same as attribute change run.

Difference between global temporary table and with clause

what is the difference between global temporary table and with claue .(with clause is used as table in select query)

what is the difference between global temporary table and with claue .(with clause is used as table in select query)Its big difference between the two.
Global temporary table exists for a session or a transaction while, with clause lives only for a query.
GTT is a named permanent storage table whose data flushes away on session exit or at end of a transaction while WITH clause just provides names to a reference data within a query (which is as good as having union subquery in FROM clause)
eg
SQL> with c as
2 (
3 select 1 id1, 2 id2 from dual union all
4 select 2,4 from dual union all
5 select 3,5 from dual)
6 select * from c
7 /
       ID1        ID2
         1          2
         2          4
         3          5
SQL> ed
Wrote file afiedt.buf
1 select *
2 from
3 (
4 select 1 id1, 2 id2 from dual union all
5 select 2,4 from dual union all
6* select 3,5 from dual)
7 /
       ID1        ID2
         1          2
         2          4
         3          5But GTT serves its purpose very well in case of session specific transaction and the scnearion with multiple users working on same data.

Difference between alternative calculation type and alternative condition b

What is the difference between alternative calculation type and alternative condition base value?

Hi Nitin
Alternative calculation type:
Suppose my gross price (PB) is Rs.100 for some metal per kg and I want to calculate surcharge based on todays RBI index of commodity rather than simply giving some 2%. I want to account todays RBI index in determinig Condition value.
It is possible to do that by little alteration of regular routine.
Alternate Condition base value:
I am procuring 5 different variety of pens at different quantities at varying rates from 0 to 25 in a sing le PO. And I get the total header value of 1000. I will get a discount of 10% if the PO value reaches 1000. I have to subsequently pass on the discount of Rs.100 now to all the 5 line items. In general SAP calculates it based on the values of each line item and proportionately distributes. However If i want this discount to be distributed according to the quantity of each pen. You can acheive this with little alteration of Routine.
Hope this clarifies your doubt.
If found helpful, Pls reward.

Difference Between OTL Retro Entry and Salary Change Retro Entry in Payroll

Hi Everyone,
We are developing a custom interface from Payroll to Projects which will post all the entries from OTL.
OTL->Payroll->Projects
We are stuck with identifying the Difference Between OTL Retro Entry and Salary Change Retro Entry when we process Retropay in Payroll.
After retropay, we come we would see the retro element entries for both them with same name and creator_type is either EE or RR for both them.
In our interface we have to treat retro entries through OTL and Salary Change in differentway.
Has anyone can give some suggestions on this please asap as we are heading towards UAT very soon.
Thanks in Advance..!!
Anand

Hi Anand,
Element with creator_type RR are created/generated by Retropay.
Elements with creator_type EE are regular element entries.

What is the difference between Recon. Account and Alternative Recon. Accoun

hi
any body please tell me . What is the difference between Recon. Account and Alternative Recon. Account.

Hello sairama,
Reconciliation account- For each subledger account , you must keep at least one reconciliation account in the general ledger. When you post to an account in the subledger, the system automatically posts to the corresponding reconciliation account. The "Receivables from goods and services" account is an example of a reconciliation account for customers. Enter Customer in the Reconciliation account for account type field. Enter a Vendor in this field for a vendor reconciliation account. Using the reconciliation account procedure, it is possible to create a balance sheet and a profit and loss statement at any time, since the amounts posted to subledger accounts are also posted automatically in the general ledger.
During regular reconciliation, you check whether the balance of the reconciliation account matches the balance of the corresponding subledger account.
You define reconciliation accounts by specifying in the G/L account master record the account type (such as fixed assets, vendor or customer) for which the account is to be used. In this way, the account can only be assigned to accounts in the corresponding subledger. You set the assignment of the subledger account to a reconciliation account in the master record of the subledger account. You cannot post to reconciliation accounts manually .
============================================================
Alternative Reconciliation account- Special G/L transactions are identified by a special G/L indicator. The system uses the specifications (posting key and special G/L indicator) to determine the alternative reconciliation account.
When you post a special G/L transaction, the system does not post to the normal reconciliation accounts but instead automatically to alternative accounts, that is, special G/L accounts. Consequently, you do not transfer the balances of these accounts either. Instead, the system posts to the appropriate accounts automatically when the open items are transferred.
Hope I had been able to help you. Please assign points.

Difference between r/3 report and bw report

Hi
can u give me detail difference between r/3 report and bw report.all information is geting in r/3 y bw report
plz send me any document if u have
prasanth.k

Hi,
These two reporting seem to function similarly with slice and dice.
A) The major benefits of reporting with BW over R/3 are in terms of performance and analysis.
1. Performance -- Heavy reporting along with regular OLTP transactions can produce a lot of load both on the R/3 and the database (cpu, memory, disks, etc). Just take a look at the load put on your system during a month end, quarter end, or year-end -- now imagine that occurring even more frequently.
2. Data analysis -- BW uses a Data Warehouse and OLAP concepts for storing and analyzing data, where R/3 was designed for transaction processing. With a lot of work you can get the same analysis out of R/3 but most likely would be easier from a BW.

The difference between AIR-ANT5135D-R and AIR-ANT5135DB-R

Hi,
Anyone know what is the difference between AIR-ANT5135D-R and AIR-ANT5135DB-R ?
From the dynamic configuration tools for 1252 and 1242, AIR-ANT2422DB-R is inside one of the antenna option.
However, I can't find it in the "Cisco Aironet Antennas and Accessories Reference Guide"
http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html
Inside the document there is only AIR-ANT5135D-R.
likewise for the 2.4 GHz, AIR-ANT2422DB-R is inside the dynamic configuration tools and not inside "Cisco Aironet Antennas and Accessories Reference Guide"
Any help would be appreciated
Thanks,
Richard

Found the difference, AIR-ANT5135DB-R and AIR-ANT2422DB-R are non-articulating antennas.
Thanks!

The difference between Telepresence Content Server and MSE 3500

Good day! Could someone explain me what's the difference between Telepresence Content Server and MSE 3500? Why do I need to obtain two these devices for sorting out my tasks? I want to understand gist of the first and the second devices.

In addition to what Jonathan posted above, here is a Capture Transform Share Solution Guide that goes over a little bit of what the TCS and MXE are and some possible deployment scenarios.
In short, TCS is used to record video conferences or lectures that can be streamed on demand or live using various streaming or distribution methods. One such distribution method is using the MXE 3500 to ingest the recordings from TCS and convert them to different media types and add in-video content such as logos etc. However, from the MXE, you can't send the video back to the TCS for viewing, you'd need to send that off to another viewing portal such as Show and Share.

What is difference between Service map iview and Workset Map iview

Hi Experts,
Can anyone tell me the difference between service map iView and Workset Map iView.
When I am creating these iViews, its seams both are same. I canu2019t find difference still, can anyone help me out of this
Thanks in Advance
Janardhan

Hi,
Service Map Iview:The Service Map iView is an ERP-specific variant of the portal Workset Map iView. It serves as a central point of entry and guided access to the services of SAP service modules such as the Manager Self Service (MSS) module, or the Employee Self Service (ESS) module.
Workset Map iview:A Workset Map is the equivalent of a site map, providing users with explicit information on the functionality that is available in a given workset. It is based on an iView, and serves as a central point of entry and guided access to the contents of a workset.
if you want to more info pls go thr the below thread

What is difference between ADF Task Flow and Faces-Config - when delpoy ?

What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
Where is the problem?
Best regards!

Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?
Best regards!

What's the difference between a web site and a web application?

I'm stumped trying to come up to a difference between a web site and a web application for myself. As I see it, a web site points to a specific page and a web application is more of some sort of 'portal' to content and information.
But where I'm stuck is that a web application is still viewed through a browser (is it not?) and a web site can still view content dynamically, making the line between web site and application prety gray.
For instance, does a web site using ASP.NET or AJAX (I assume ASP.NET is AJAX's proprietary sibling, if not, ignore ASP.NET AND concentrate on the AJAX), becomes a web application because it can retrieve data dynamically and asynchronously or would a website
using PHP and a CMS be more of a web application because it forms the pages on request, based on the request of the client and its content in its databse?
Or maybe I'm totally wrong here - what differenciates between a web application and a website?

This is totally personal and subjective, but I'd say that a website is defined by its content, while a webapplication is
defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that's dealt out to all visitors, while a web application depends on interaction and requires programmatic user input and data processing.
For example, a news site would be a "website", but a spreadsheet or a collaborative calendar would be web "applications". The news site shows essentially the same information to all visitors, while the calendar processes individual data.
Practically, most websites with quickly changing content will also rely on a sophisticated programmatic (and/or database) backend, but at least in principle they're only defined by their output. The web application on the other hand is essentially a program that
runs remotely, and it depends fundamentally on a processing and a data storage backend.

There is no real "difference". Web site is a more anachronistic term that exists from the early days of
the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites).
Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.
If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels
more like an application as a web app.
The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com
as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.
Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some
http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.
