What are SERIALLY_REUSABLE and RESTRICT_REFERENCES pragmas, when can used?

Hi everyone,
I have recently joined in Discussion forums and feeling very excited to read blogs.
My question is about SERIALLY_REUSABLE and RESTRICT_REFERENCES pragmas.
what are these pragmas and when can we use them?
It would be greatly appreciated if anyone can answer this.
Regards,
Sachin Jaiswal

Go to http://tahiti.oracle.com, type in your searchwords, choose the database versions you are using and read the results.
e.g.
serially_reusable version 11.2
restrict_references version 11.2
Also this is not really related to forms, so for this type of question the SQL and PL/SQL forum might be more apropriate:
PL/SQL
but as you can see looking up in the documentation brings you answers to your questions in no time ;)
cheers

what are these pragmas and when can we use them? please give me practical example as I have understood them
in Oracle documentation but not able to use practically.
It would be greatly appreciated if anyone can help me.

SERIALLY_REUSABLE : This pragama indicates that, the package states are stored only for the block it is executing. Means teh package states are not stored for the session. In this way the constants defined in the package wont be available for the whole session.
RESTRICT_REFERENCES: This pragma is to check, packaged functions have the expected purity during compilation itself. For example, if you want to assert that a packaged function wont do any db writes, you can use as below.
create package p1 is ..
function test_fn return number;
pragma restrict_references(test_fn,wnds)
end p1;

What are waveform and thumbnail caches, when to delete?

Trying to configure my system and wondering what are waveform cache files and thumbnail cache files. Also, I have a constant frames folder. When can I delete these files? Shane, got your DVD, love it.
Best,
Tom

Tom:
what are waveform cache files and thumbnail cache files.
They are files that FCP uses to store like "temporary" files with your audio wave forms and thumbnail images of your clips. You can delete those folder contents when you want; FCP will rebuild them when needed.
Also, I have a constant frames folder.

What are the AME Tables that I can use to get approvers list

Hi
Please provide me any information about the tables by which I can get approvers list.
Thanks
Amit

Tthe application communicates with AME when a transaction is initiated in the application, and then each time an approver responds to the application‟s request for approval of the transaction, until all approvers have approved the transaction. AME records each approval, and recalculates the approver list for a transaction each time an approver responds to a request for approval of the transaction.] As far as AME is concerned it calculates approver list at runtime .
"The application(Purchasing , AP etc) communicates with AME when a transaction is initiated in the application, and then each time an approver responds to the application‟s request for approval of the transaction, until all approvers have approved the transaction.

Only the carrier to whom the device is locked can authorize it's unlocking. Contact the carrier to see if they offer unlocking and if you qualify.

You have a Puerto Rico address on your account ? From a quick search I've found one site from somebody in Puerto Rico that includes a screenshot for an app receipt showing tax of 7 cents added to a 99 cent purchase. Are you able to view the purchase history on the account that you've been using, and see what prices show on them (e.g. if the store's listed price or price plus tax) : Store > View Account menu option on a computer's iTunes, then 'see all' link next to the Purchase History section.

I took some videos using my iPhone 5c and uploaded them to my computer. I can play the videos in iPhoto, but when I open them in QuickTime, they are dark and silent. Why can't I see them in QuickTime?

Make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

0.41GB of my iPod Touh 4G' is taken up by something called 'Others'. What are 'Others' and can they be deleted or are they an essential part of the iPod and embedded in it? If not essential how do I go about deleting it to enable me to add other pictures

0.41GB of my iPod Touch 4G's capacity is taken up by something callked 'Others'. What are 'Others' and will it be o.k to delete them? If so how do I go about doing it as there is no trace of a file on either iTunes or my iPod?

Other content is typically miscellaneous data used by applications you have installed - could be save data (e.g. for games), or documents you've created. There's no easy way to determine precisely what it is, but the only way to clear it is to either delete it from within the respective application, or remove the associated application altogether - neither of which are typically practical.

What are ROWID and ROWNUM? Are they stored in database and where?

Hi All,
can anybody please answer this question
What are ROWID and ROWNUM? Are they stored in database and where?
Thanks,
Srini

ROWID can be thought of as a pointer to the physical location (on disk) of the (table) row.
From a ROWID value, Oracle can extract the file, block-within-that-file and offset-of-the-row-within-that-block. Using these, Oracle can directly access a disk block to retrieve a row.
ROWNUM is a just sequence number of a row within a result set of a query.
As said by other repliers, both are not stored. They are 'constructed' when you reference them inside a query.

What are valid and invalid email address characters

What are valid and invalid email address characters in Exchange 2010, for example can you have Conan.O'[email protected] is there a document that shows the valid and invalid sysmbols?

Hi
The format of email addresses is
local-part@domain where the local-part may be up to 64 characters long and the
domain name may have a
maximum of 253 characters - but the maximum 256 characters length of a forward or reverse path restricts the entire email address to be no more than 254 characters.[1]
The formal definitions are in RFC 5322 (sections 3.2.3
and 3.4.1) and RFC 5321 - with a more readable form given in
the informational RFC 3696[2]
and the associated errata.
Local part
The local-part of the email address may use any of these
ASCII characters
RFC 5322 Section
3.2.3:
Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
Digits
0 to
9 (ASCII: 48-57)
Characters
!#$%&'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 94-96, 123-126)
Character
. (dot, period, full stop) (ASCII: 46) provided that it is not the first or last character, and
provided also that it does not appear two or more times consecutively (e.g. [email protected] is not allowed.).
Special characters are allowed with restrictions. They are:
o
Space and
"(),:;<>@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 91-93)
The restrictions for special characters are that they must only be used when contained between quotation marks, and that 3 of them (The
space, backslash \ and
quotation mark " (ASCII: 32, 92, 34)) must also be preceded by a backslash
\ (e.g.
A quoted string may exist as a dot separated entity within the local-part, or it may exist when the outermost quotes are the outermost characters of the local-part
(e.g. abc."defghi"[email protected] or
"abcdefghixyz"@example.com are allowed. Conversely,
abc"defghi"[email protected] is not; neither is
abc\"def\"[email protected]). Quoted strings and characters however, are not commonly used.
RFC 5321 also
warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".
The local-part "postmaster" is treated specially - it is case-insensitive, and should be forwarded to the server's administrator. Technically all other local-parts
are case sensitive, therefore [email protected] and [email protected] specify different mailboxes. However most organizations treat uppercase and lowercase letters as equivalent, and also do not allow use of the technically valid characters
(space, ? and ^). Organizations are free to restrict the forms of their own email addresses as desired, e.g.,
Windows Live Hotmail,
for example, only allows creation of email addresses using alphanumerics, dot (.), underscore (_)
and hyphen (-).[3]
Systems that send mail must be capable of handling outgoing mail for all valid addresses. Contrary to the relevant standards, some defective systems treat certain
legitimate addresses as invalid and fail to handle mail to these addresses. Hotmail, for example, refuses to send mail to any address containing any of the following standards-permissible characters:
!#$%*/?^`{|}~
Domain part
The domain name part of an email address has to conform to strict guidelines: it must match the requirements for a
hostname,
consisting of letters, digits, hyphens and dots. In addition, the domain part may be an
IP address
literal, surrounded by square braces, such as jsmith@[192.168.2.1], although this is rarely seen except
in email spam.
Examples
Valid email addresses
<tt>[email protected]</tt>
<tt>[email protected]</tt>
<tt>[email protected]</tt>
<tt>much."more\ unusual"@example.com</tt>
<tt>very.unusual."@"[email protected]</tt>
<tt>very."(),:;<>[]".VERY."very@\\\ \"very"[email protected]</tt>
Invalid email addresses
<tt>Abc.example.com</tt> (an @ character must separate the local and domain parts)
<tt>[email protected]</tt> (character dot(.) is last in local part)
<tt>[email protected]</tt> (character dot(.) is double)
<tt>A@b@[email protected]</tt> (only one @ is allowed outside quotation marks)
<tt>a"b(c)d,e:f;g<h>i[j\k][email protected]</tt> (none of the special characters in this local part
is allowed outside quotation marks)
<tt>just"not"[email protected]</tt> (quoted strings must be dot separated, or the only element making
up the local-part)
<tt>this is"not\[email protected]</tt> (spaces, quotes, and backslashes may only exist when within
quoted strings and preceded by a slash)
<tt>this\ still\"not\\[email protected]</tt> (even if escaped (preceded by a backslash), spaces, quotes,
and backslashes must still be contained by quotes)
