Different between drop,delete,truncate.

hi.
kindly what is the different between drop table,delete table,truncate table.
thanke you all .

Hi
Drop is a ddl statement which removes the existence of the table along with the data.
Delete is a dml statement which removes only the data from the table.
Truncate is a ddl statement which removes only the data from the table.
1) You can specify condition in delete statement which would remove only the specific data from the table. You cannot specify condition in truncate statement so all the data would be remove.
2) Delete keeps the records in buffers/undo segment so that you can rollback. Whereas truncate does not so you cannot rollback, moreover implicit commit is done on issuing of truncate
3) Truncate also resets high water mark of the table whereas delete does not.
Regards

Exchange rate is different between records in OB08 and records in document.

Hi Gurus,
The exchange rate is different between records in OB08 and records in calculated amount in line item. How does it happen? Not all of the documents in the same period has this problem.
For example, a document A created by FB05 on Jun 30 2010.
In OB08, the exchange rate is 6.80000. This rate was the same in the header of document A.
In the line item of doc A, I calculated the amount for line itme 1 and 2. Line itme 1 shows the exchange rate is 7.90000. Line item 2 shows the exchange rate is 16.0000. ( The exchange rate is not that exactly an interger. I put a similar exchange rate as an example.)
Could you please throw some light on these? Why some documents are okay but for some, the exchange rate is so different?
I just found that the exchange rate of some of the document line item calculated is from another currency. It shows in the line item (in question) button "More Data". Shall I know how the exchange rate was got from another currency exchange rate?
Thank you.
Emma

Release of space after delete/truncate table

Hello,
How does release of space after delete/truncate table works? Is the space used before deletion released once delete is complete or not? Will I see the space occupied by deleted table as free in dba_segments or will I need to reorganize the table (drop and recreate again?). Reason why I am asking is that I can see table with 0 rows, but in dba_segment I can see it is occupying few gigabytes....
Thank you

What's different between statfulacl and detailedacl

i just confused that what's different between stateful ACL and Detailed ACL in Hyper-V 2012R2, i know stateful ACL will create return traffic automatically
for example：
Add-VMNetworkAdapterExtendedAcl –VMName “ApplicationServer” –Action “Allow” –Direction “Outbound” 80 “TCP” –Weight 100 –Stateful –Timeout 3600
if i delete “-statful” and “timeout", then what‘s will happen，any performance issue or something else？

Looking up the PowerShell command in TechNet will explain each parameter. As will the PowerShell command Help
Add-VMNetworkAdapterExtendedAcl -parameter Stateful.

Same colors display differently between Illustrator and Photoshop

Hi there,
I would love to know why the same colors display differently between my Photoshop and Illustrator apps (CS3). For example, a logo will display much darker or more vividly in Illustrator than in Photoshop, same file, same colour values. My color settings are synchronized from Adobe Bridge to North American Pre Press 2. I've opened the logo file in RGB color mode, in both apps. It would be so helpful if both apps displayed the colours consistently.
Any suggestions on how to do this would be wonderful!
Thanks!
Bobbie

Hello Bobbie,
I am using CS3 too and let me tell you that this Illustrator version is the worst ever. You best bet is to take the "Eye Drop" tool and select the Photoshop element to match the color.
CS4 also have problems when handle placed items. Sadly I can tell you that CS2 is more reliable than CS3 and CS4.
Not even if you use Pantone colors will match, Illustrator will change the colors making it impossible to match. "Adobe Quality"

What is the different between Sharepoint fast search service and Sql server fulltext search?

HI ,
I want to kow what is the different between Sharepoint fast search service and Sql server fulltext search?
Or Can I abstract the Sharepoint fast search from the Sharepoint platform as a isolate component?
Thank you.
James

They are very, very different beasts.
Firstly FAST Search for SharePoint is the old name for the product and is only relevant for SharePoint 2010 not 2013. It got merged into the standard SharePoint search for the 2013 release.
SharePoint search is aimed at providing a Bing or Google like experience for your intranet content, as well as providing some nifty features that are purely SharePoint releated along the way. That means it can crawl SharePoint content, file shares,
outlook mailboxes, internal and external websites and probably fifty other different things if you really tried. Whilst i'm not an expert on SQL full text search I believe it's intended to provide a search feature for content held within SQL databases
and tables.
Can you run SharePoint purely for Search? Yes, definitely.

What is the different between Logical complex join and Physical join?

hi,
Do somebody know what is the function different between logical complex join in BMM layer and physical join in physical layer?
Thanks.

Thank you very much1
I understand their differentiation:
In the BMM Complex join (intelligent), means OBI picks the best way from possibly many different ways to join using physical join. FK join forces the same join always, which limits flexibility.

Regards ;

WIRE:
Wire is transfer of amount due directly to the supplier's bank it is an electronic transfer of funds
This mode of payment is used for international suppliers.
It can be paid in foreign currency or USD.
Wire payments are same day payments.
EFT:
EFT ensures funds transfer from one bank account to another using electronic links.
Can be used to make payments into domestic banks (within US) in USD only.
It is faster than check payments.

Payment terms different between sales docs

Hi Gurus.
Why do I have payment terms different between sales doc and billing doc for the same customer?
Detail: the sd and company code vision has the same value in customer master data (xd03, vd03).
Thanks in advance!
Renato

Dear Renato
Go to VA02, input the sale order and execute. There click on Environment from top menu bar followed by changes. You would find four options to choose. Select
- Additional info and
- Time of Change
This would give you who have changed the datas related to that sale order.

Why do my RAW files appear different between programs?

I have rendered a series of three RAW images as an HDR file in Photoshop CC, saved as a 16-bit TIFF file, and imported it into Lightroom. The image appears different between the two programs. The Lightroom image appears to have some editing done already and is not nearly as flat as the image in Photoshop. I have made sure my Adobe software is up to date concerning both programs and the camera raw information that can be updated via Adobe.

The iPad stores the raw photo data, but displays an iPad optimized version of the original image in its place.
This image is usually an optimized JPEG image, so the quality will not be the same as the raw image file.

Parent Child Relationships between Drop Down Menus

I have a request for additional functionality. Parent child relationships between drop down lists.
for example,
the first dropdown, could contain North, South, East, West & assign values of 1, 2, 3, 4.
the second dropdown, could contain a filtered set of data depending on the option from the first dropdown,
so the data could look like this in the second drop down:
Manchester 1
Leeds 1
London 2
Southampton 2
Norfolk 3
Newquay 4
so if I select North in the first dropdown, the second drop down would contain all the items with a value of 1, so Manchester & Leeds.
I have managed to get round this using conditional show & hide, but it is much messier on the design screen & also the way in which the data
will be returned is very very messy - seems like a simple addition which would improve the functionality no end.

Playlist order different between iPhone and iTunes

I updated to 3.1 and iTunes 9. In iTunes lets say i have 5 songs in a playlist. Lets say I Will Not Bow, Let The Beat Build, So Sharp, Good Time, and Fall. But on my iPhone in the same playlist they are ordered Let The Beat Build, Good Time, I Will Not Bow, So Sharp, then Fall. Why would they be ordered differently between the two? Anyone else having this problem?

There is a solution for this problem. Right click your smartlist; select edit smartlist; UNCHECK "live updating"; Then sync your files. This will adjust your device (iPod, iPhone) list to the way it is in your iTunes list.
It does mess up adding new songs to your smartlist if you use a specific method of list names which adds a song automatically. If this is the case, check "live updating" using the method above, add your song, then uncheck it again to keep the order as it is in iTunes.
Hope this helps. It works for me everytime a list messes up. I read about this fix somewhere in these forums, tried it and it works like a charm!!
