How to convert a date value into week value?

How to display the date value like '20010203'
into the week number of the year 2001?
When i type in the following sql
select week(chg_time) from site;
I got this error message
ORA-00904: invalid column name

use the to_char function, to format the date into a week number (then you might need to convert that to a number using to_number)
select to_char( sysdate, 'WW') from dual`

Hi Shabarish,
The code works but what if the input is something like [ 10.000-] i.e. with some spaces before 10.000- and the output as per your code comes as [- 10.000]. How do we tackle such cases if there is inconsistency in data i.e. some values come as [ 10.000-] i.e. spaces before the number and some values as [12.000-].
The output of this will come as
[- 10.000]
[-12.000]
How to make it as
[-10.000]
[-12.000]
Regards,
Shaibayan

How to convert a date field with format (dd,mm,yyyy) to format (mm,dd,yyyy)

Hello.
How to convert a date field with format (dd,mm,yyyy) to format (mm,dd,yyyy)
I have text field which has a databind to a date field. When I click on it, we can select the date, it is added on the format (dd,mm,yyyy). When I want to insert this date field to a database It doesnu2019t allow me to do it because it will only accept date field on the format (mm,dd,yyyy)
I tried to store this format on a date variable and I get a message saying that is impossible to convert a string into a date.
Regards,
Jose

Hi Jose,
usually you format strings in c# like
string.Format("{0:yyyyMMdd}", insertyourstring);
in your case
string.Format("{0:MM/dd/yyyy}", insertyourstring);
[look here|http://idunno.org/archive/2004/14/01/122.aspx]
there are more details
if everything fails split the string with Mid()
or ask me

How to convert a protected document into a PDF?

Hello,
I need to develop a plugin that needs to convert a protected document in office format into a pdf. I looked into the sdk and found the method AVConversionConvertToPDFWithHandler (). But can this method also apply the digital rigths of the protected document to the newly created pdf?
Is there any other way to convert a protected document into a pdf and at the same time apply the rights to the pdf? I don't want to use Adobe LiveCycle for digital rights management.
What are the requirements to develop a DRM plugin for acrobat?
Please Help!
Thanks in advance!

The AVConversion APIs will use Office itself to perform the conversion (well, the rendering part). I would ASSUME that when Office opens the document, it will ask for any necessary passwords or other information to determine if the user has the rights to view and/or process the content of the document. If they do, then the conversion will succeed otherwise it will fail. The PDF will not have any DRM applied to it, since we don't know anything about the Office DRM options.
If you wish to apply DRM to the PDF, you will need to do that yourself or using tools such as LiveCycle Rights Management.

How to convert a PDF file into a full editable WORD file?

Hi,
I tried to convert a pdf file into word but it is not fully editable. I can edit the title from the main page and that's it. The rest of the word document is saved as image. I tried editing teh pdf file but that one is not working either.
Please help on how to convert a PDF file into a full editable WORD file.
Thank you

Not all PDF files are created equal. When a PDF file is created with Adobe Tools it is usually "tagged" with information about the fonts the images, the layout etc... This way when the PDF is saved to a new format like PPT or DOC then the results are usually usable. However, if you have a PDF file that was not tagged for some reason then run the Accessibility tools on the PDF to acquire some basic tagging. This may get you a better result. Also if you have a PDF that is an image, then you may want to run OCR on it.

How to convert my MM alias into an AppleID to use it with iCloud?

I used MobileMe and created a mail that became my Apple ID. Then I created an alias that became my main e-mail so now with iCloud I wish that aslias could become my Apple ID. I don't care to loose the first Apple ID but "How to convert my MM alias into an AppleID to use it with iCloud?"

You cannot convert an alias to Apple ID.
You can transfer your MM to iCloud with your main Apple ID.
There will be your alias as well.
