depending on how many values you have, you could store the results in memory, a vector or similar collection.
Then close the select statement, and insert the values from your vector into the table.... should work then.
Or, there may be a way of creating an updatable resultset ?
This question is better directed at the
"Java Database Connectivity (JDBC) & Transactions (JTA/JTS)" section of the forum. Maybe post a questions there, ensuring you give the URL of this question here too to avoid cross-posting.

Update while selecting

Is there any way in oracle where we update while selecting.
I have a situation where I select a few rows from a table.
Then I have to update those all those rows witrh some date as sysdate.
I want to make sure that the rows I have selected are only updated and not a single new one.
ex:
select
process something.
update table set filed=sysdate where pk_col in (select --it is the same as 1st select );
but in real time,
when i select 1st time i get 40 rows.
I process them.
now i have to update just those 40 rows,
but this time when I say
update (select --its a second read.... this time select gives me 42 rows)
maybe someone was working and he updated the table and I got 2 more rows.
But as i processed 40, i want to update only 40 rows.
So how can i be sure.
Any ideas. please help.
1 solution is to have a cursor and do the processing and updaing in the cursor.
I process 40 rows and i update only those 40 rows in the cursor.
other way, update when i select. i it possible.
please let me know.

You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

You should have said that so that those trying to help aren't wasting their time suggesting steps that you have already taken.
Have you tried just powering down for a while and then try again a little later? Try another WiFi network? Reset your router?

So I just did this on my iPhone 4 and it worked like a charm it unlocked it immediately. My phone was put into recovery mode and I know that not all data is deleted it just puts the phone into a sort of hibernation in order for the files to stay uncorrupted. I went to http://www.recovery-ipad.com/iphone-stuck-in-recovery-mode.html downloaded the software it unlocked my phone in a matter of minutes. Calls, messages, photos, apps, and voicemail was all there as if it never happened If you leave it unregistered you don't have to pay for it works for either windows or mac. Hope this helps!

TS3297 after updating my iphone 3gs to ios6 a message "we're sorry, we are unable to continue with your activation at this time." pls help!

after updating my iphone 3gs to ios6 a message "we're sorry, we are unable to continue with your activation at this time." pls help

I have the same problem after updating to the latest iTunes. I purchased an iPhone 4S this past summer and gave my 3GS to my 6 year-old minus the SIM card-- an instant iPod Touch. Things were fine until the latest version of iTunes 11.0. Until I updated to 11.0.1, iTunes would not even "see" the iPhone.
How do I get past the insistence to activate the phone? Right now, it's a useless brick.

Welcome to the Apple Community.
You can only locate your device when it is logged into iCloud and 'Find My Phone' is enabled, additionally the device will need to be switched on and connected to a wifi or cellular network.
Unfortunately, you cannot activate iCloud or 'Find My Phone' remotely.

I am trying to setup iCloud account and when I login I see a popup. The Maximum number of free accounts have been activated on this iPhone. Pls, help me fix it. What other accounts? Thanks

Then you'll have to use another iOS device or Mac running OS X Lion or higher to create a new account for you to use on your phone. If you don't have one, perhaps a friend would allow you to create and account on their device (note: this will use one of their three maximum accounts). To do this, they would need to go to Settings>iCloud, tap Delete Account (which will delete the account from their device but not from iCloud), then allow you to sign back in with your ID to create the new account. Then tap Delete Account to delete the new account from their device, and finally, sign back in with their iCloud ID to restore their iCloud account to their device. Then you can sign in with your ID on your phone in Settings>iCloud and use the new account.

Hi Everyone. I have an old Mac Book. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive?Pls.help.

Hi Everyone. I have an old Mac Book with software updated to 10.6.8. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive? Pls.help. Tks.

Depending on which email client software you use
the files should be in 'your home folder' library, esp.
if you use Mail application.... ~/Library/Mail
Since you don't specify what mail application,
that would most be associated with the file.
I notice there are some items to the right of your post
where it says "more like this' so that may be worth a
look to see if similar issues were answered. Also, the
Help viewer in your system is a searchable database.
Seems that google also brings up fair information, too.
Do you have a complete bootable clone of your entire
Mac system on an externally enclosed hard disk drive?
Good luck & happy computing!

HT204053 sir; i can't import song and videos from pc to my iphone pls help me

sir; i can't import song and videos from pc to my iphone pls help me

We are fellow users here on these forums, you're not talking to iTunes Support nor Apple - if you would like help then you will need to provide more information than 'can't import' e.g. how are trying to sync content and what happens when you do it ?
You have the latest version of iTunes installed on your computer, and your phone appears in it when it's connected to your computer ? If not then see if this troubleshooting page helps : http://support.apple.com/kb/TS1538
You should be able to sync music and films/TV programmes by selecting your phone on the left-hand sidebar of your computer's iTunes (you can enable the sidebar via control-S on a PC) and then using the tabs on the right-hand side of the iTunes screen to select and sync your content
Is that how you are trying to do it and it's not working ?
If you haven't synced your phone to that computer before then you may also find this page useful : https://discussions.apple.com/docs/DOC-3141

You can only specify the READPAST lock in the READ COMMITTED or REPEATABLE READ isolation levels

Hi, I have a piece of code that works fine in SSMS as T-SQL. When I put the T-Sql inside a SP, I get the error :
You can only specify the READPAST lock in the READ COMMITTED or REPEATABLE READ isolation levels
The script starts is as follows (only select)
SET NOCOUNT ON
Set Transaction Isolation Level Read Committed
Set Deadlock_Priority Low
Select......
From MyTable WITH (NOLOCK)
GROUP BY .....
Order BY ....
works fine as I said in SSMS as T-SQL but the SP generates the following
Msg 650, Level 16, State 1, Procedure usp_TotalMessages, Line 15
You can only specify the READPAST lock in the READ COMMITTED or REPEATABLE READ isolation levels.
By the way, when it says line 15, from where we should start counting, is it from The USE DB statement which includes comments as well as Set ANSI....or should we start counting from the Alter PRocedure statement
Thanks in advance

Set Transaction Isolation Level Read Committed
Set Deadlock_Priority Low
Select......
From MyTable WITH (NOLOCK)
GROUP BY .....
Order BY ....
First you define transactionlevel = "Read Committed", then you use a query hint "NOLOCK" which is equivalent to "Read Uncommitted"; so what do you want now, committed or uncommitted, you have to decide.
