You should better post your question to a more related Forum, like Transact-SQL or SQL Server Database Engine; this Forum is for samples & community Projects.
Have you checked the execution plan if indexes are used?
You could update the data in chunks, e.g. 10.000 rows per execution. For this you have to add a TOP clause and a filter to update only those, who are not updated yet.
update TOP (10000) Employees
set Status = 'Close'
where statusid IN
(select statusid
from MyView
where DownloadedDate ='2014-07-27 00:00:00.000')
AND Status <> 'Close'

Updating IOS 8.02 on 4s,when service provider is changed or not available,phone goes to search mode & its drain battery very fast,it does not stop even in charging mode,it goes to zero.(Even in switch off mode) only get charged in Airplane mode.why?(with different Sim cards)
RBVAIDYABecause GPS has nothing to do with WiFi, cellular signals, or data of any sort. GPS is implemented by signals sent by satellites that are received by GPS receivers. The receivers process the information from the GPS satellites and calculate your location. GPS never sends data anywhere; GPS functionality is receive only.
If you have WiFi or cellular data turned on this can improve the accuracy of GPS, because the GPS receiver can then use the known location of cell towers and WiFi networks to refine the GPS location. GPS by itself has an accuracy of 10 meters, or about 34 feet. Using the additional information from WiFi and cellular data this can be brought down to 3 meters (10 feet). This mode is called Augmented GPS, or A-GPS. -
my iphone automatically locked and it does not open again,but if u call the sim that was inserted you will hear that it was active,so please help me how to open my iphone 4,no display appeared if you touch the switch button,
Hello arlyn-cavite,
If the screen is not showing anyting when you press any of the buttons you may want to try these steps.
From article iPhone: Hardware troubleshooting http://support.apple.com/kb/ts2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Take care,

I purchased Adobe CS4. I am now being asked for my serial number and when I put it in the program does not recognize it for Acrobat Pro 9 though it does for PhotoShop, Bridge and the rest of the suite. What can I do?
Contact support if you have serial number issues. Otherwise start by checking this stuff:
Sign in, activation, or connection errors

hi help unlock the phone happened after we installed a new programa we can not get the activation password and ID, I know and still does not stop the phone bought in Israel and what documents should be sent to confirm that my phone Please read through the help
What I am saying is ..........
The iPhone HAS to be active making calls on the UK carrier network for the carrier to identify as "theirs" and therefore eligible for the Carrier to unlock
The way to achieve this is to use a PAYG sim making and receiving calls to establish a customer relationship with the Carrier and then follow the Carrier's process to unlock
With a PAYG it usually means adding a specified (by the carrier ) amount usually £15 /£20 depending on the carrier
This is how O2 function and according to Gemma this is how Vodafone work -
i am trying to sync an ipad to a power mac g5. i bought and upgraded to osx 10.5 and have tried to download and 10.5.6 or higher, but i keep getting same message: "you cannot install mac os x update on this volume. this volume does not meet requirements for this update". help!
Mac OS X 10.5.8 Combo Update
Java for Mac OS X 10.5 Update 5
To me, in all such updates, goes without saying maybe: backup, repair permissions, repair your drive (Disk Warrior does more reliable and thorough job, and it comes out to pennies if you don't wait until needed). Clone your system so you can restore or use the backup - just in case.
I'd even do a fresh format after your clone is done and do a full OS clean install and update, and then a quick import from Setup Assistant.
Mac computer with USB 2.0 port
Mac OS X v10.5.8 or later
iTunes 10.2 or later recommended
(free download from www.itunes.com/download)
iTunes Store account
Internet access
I'm going to assume there is something with the partitions on the drive, partition table most likely, though I know I've seen others with that error message - doesn't really point to cause, rarely does (make sure latest firmware update etc is sometimes included but again, we know that isn't why). -
iTune Software locks up when I connect my iPod Classic and it does not recognize iPod is connected and does not sync musice as it use to. Looking for ideas to try. Running updated iTune software and have reset iPod?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
- Make an appointment at the Genius Bar of an Apple store.
Apple Retail Store - Genius Bar
It also could be due to a defective Lightning cable. Other uses have had problems with the cable. -
I have gmail preloaded in a section of my google home page. But when I click on the gmail link itself it only posts email from a few days ago when this started and does not show any of the newer emails
I'm not sure what you try to do.<br />
If you type or paste http://odb.org/ in the location bar then that website should open.
Only if you use the https: protocol then encryption is used and the technical info will show that like you see with this website (Verified by Equifax).

Execution does not end even after all records updated..
Hi,
I have plsql code like :
declare
begin
for x in ( select .......) loop -- about 4000 times
for y in ( select ............) loop -- about 50 times
end loop;
-- some code goes here to manipulate clob data
-- like creating free temp clobs - use - then free them
-- Update statement that update some table using clob values.
insert into tablex values(sysdate);
commit;
end loop;
end;
Here I can monitor from other window howmany records are inserted into tablex and howmany updated in update statement by...
select count(1) from tablex;
After 50 mins i can see that all records are updated but...
plsql code does not end its execution it continues even after all records are updated..untill i have to kill the session or let be run for long time.. :(
I can not understand why this it is not ending execution..
What could be the problem ...Hi,
Here it is.....
declare
v_text_data TableA.text_data%type;
v_clob clob;
type dummyclob_t is table of clob index by binary_integer;
dummyclob dummyclob_t;
v_str varchar2(255) := 'ddfsajfdkeiueimnrmrrttrtr;trtkltwjkltjiu4i5u43iou43i5u4io54urnmlqwmreqwnrewmnrewmreqwnm,rewqnrewqrewqljlkj';
begin
select data bulk collect into dummyclob from sfdl_clob; -- five rows containing clob data upto 1MB
for x in (select object_id
from TableA
where object_type = 'STDTEXT' ) loop
dbms_lob.createtemporary(v_text_data,TRUE);
for y in (select '<IMG "MFI_7579(@CONTROL=' || ref_id || ',REF_ID=' || ref_id || ').@UDV">' temp_data
from TableB
where object_id = x.object_id) loop
v_text_data := v_text_data ||
case
when trunc(dbms_random.value(0,7)) = 0
then chr(10)
else v_str
end ||
y.temp_data;
end loop;
select text_data into v_clob from TableA where object_id = x.object_id for update;
if v_text_data is not null then
dbms_lob.append(v_clob,v_text_data);
end if;
dbms_lob.append(v_clob,dummyclob(trunc(dbms_random.value(1, 6))));
dbms_lob.freetemporary(v_text_data);
insert into xyz values (sysdate);
commit;
end loop;
end;
Thanks for your time..:)

This is first Ipod for me - I have had less than one day. Screen is frozen with itunes emblem and cable. Unable to refresh/restore or do anything with ipod. I turn off/on and get the same frozen screen. My computer does not recognize ipod. Itunes does not recognize ipod so I cannot restore.... Should I take this ipod back and get a new one? Is this normal?
Before you can use the iPod you have to activate it by connecting it to a computer with iTunes. Try the following to get your computer to see the iPod so you can activate the iPod.

THERE IS A PROBLEM IN OPENING ANY FILE. WHEN OPENING - A RAPID SUCCESSION OF FILES OPEN, ONE ATOP THE NEXT, WITHOUT SHOWING FILE'S CONTENT. THIS CONTINUES FOR QUITE A WHILE. I MUST TURN OFF COMPUTER. IT IS NOT POSSIBLE TO CHOOSE ANY OTHER FUNCTION WHILE THIS IS HAPPENING, IE : WHEN OPENING A FILE. AS IN , I CANNOT OPEN GOOGLE OR MAIL, ETC. AND THE FILES KEEP OPENING AS UNTITLED. SO I AM NOT ABLE TO OPEN ANY ONE FILE, AND SEE ITS CONTENT, THEY JUST KEEP STACKING LIKE EMTY PAGES ONE ON TOP OF THE NEXT.

Timestamp when saved in text file and reloaded does not give correct dates
Hello
I am struggling with time stamp. I have almost corrected the problem but it is not as good as I expect it to be.
I have data in the main vi which logs into text file with time stamp for everyday results logs.
I then pull all this data to display on waveform graph with the performance data on y axis and time stamp on x axis.
I convert the time stamp data from string back to time stamp using scan from function in string pallette. When I run the waveform graph vi. The time stamp data is not correct one. I see year values beginning 1974 etc. I change these values to 2011 and the correct dates and then could see the accurate logged data from data logger but I would like to have the starting date in my logged file the left most date on x-axis. I try modify dates in display format section of waveform graph but I think it gives the values in seconds which doesn't make much sense to me. Is it possible to automatically set the starting value of the graph as the first date in the logged file? I am new with using time stamps. Any feedback will be appreciated.
Kind Regards
AustinHi Austin,
"Is it possible to automatically set the starting value of the graph as the first date in the logged file?"
Sure: Use autoscaling, format x-axis as time and use waveforms with correct t0 value...
For all other questions you should attach a VI to show your current state of programming!
