• Is it necessary that 'we should select count (*)' before deleting the recor

  Hai...
  
  I need to delete a record in my application for which I wrote a process of pl/sql below...

  Symbol varchar2 (20);
  CTN number (1);
  
  BEGIN
  
  Symbol: =: P1_HIDDEN_FLAG;
  Select count (*) in ctn to emp1 where EMPNO = symbol;
  
  If NTC > 0 then
  Remove from emp1 where EMPNO = symbol;
  
  End if;
  End;
  
  
  why we must select count (*) table... If we try to remove a record that is not available in the table... How can we handle this Exception? There are also that "we should select count () before you delete the record from the table... *"
  
  Please tell me...
  
  David...

  Hello

  You can use SQL % number of LINES:

  delete from emp where empno = p;
  if sql%rowcount = 0
  then -- Nothing deleted!
  end if;

  Before selling your watch:

  • Pair it with your iPhone (if you bought another);
  • Disable iPhone pairing using the application of the watch.

  This will erase your watch and is also a reliable way to remove Activation lock him (so that a buyer will be able to pair the watch with their own iPhone).

• Should I uninstall before installing PS CC Photoshop CS5?

  Should I uninstall before installing PS CC Photoshop CS5?

  It is not necessary.

  in general, you should leave it installed. you might need some plugin/device which is not compatible with the cc ps.  It's not likely, but you can wait and if you have no use for cs5 in a month or two, disable if (help > disable) and then uninstall it.

  and to be sure, you must secure your cs5 serial number in case you cancel cc a day and you want to reinstall your program cs5.

  I just bought 12 elements. Should I uninstall before installing the elements 12 Elements 6?

  Hi Dm606,

  You don't need to uninstall Photoshop Element 6 before installing

  Photoshop SetupUpdates12.

  However, it's totally your voluntary decision to uninstall PSE6 but he won't give you any

  problem if the versions coexist.

  I hope this helps.

  Please let me know if you have any further questions.

• What consideration we should have have before creating the tablespace

  Hello
  I was asked this question in an interview. I have a large volume of data (for example 80 GB). Now, I have to create a tablespace to contain these data. What consideration we should have have before creating the tablespace.
  In fact, I could not answer after a lot of research, so I post here.
  
  Concerning

  Hello

  In 10g, you must create a locally managed Tablespace (MEASURE of the LOCAL MANAGEMENT) If you know the
  size of your Tables/indexes you can choose the size of the scale with the option of UNIFORM SIZE.
  If you have small and large Tables / Index, then choose the AUTOALLOCATE option.

  It is recommended to use SAMS with the SEGMENT SPACE MANAGEMENT AUTO option and then the PCTUSED
  is auto tune by an internal algorithm and FREELIST are managed by a bitmap. With this option, it is best to
  be with the last group of hotfixes.

  About BIGFILE Tablespace, if you use BIGFILE tablespace, you will have just a data file which can extend up to
  4G block (thus 32 TB if you have db_block_size = 8KB). And SQL syntax allow you to manage the 'big' with data file
  the same command for the Tablespace.

  But you should care the limit of your OS. Imagine that your operating system or the file system does not support very largefiles then,
  you have no advantage over the use of Bigfile tablespace. Also, you might have more than 1 data file.

  Smallfile Tablespace using your data files should not exceed 4M block (so 32 GB for 8 KB / block) but you can have
  up to 1022 datafiles on your Tablespace. So eventually, if you use the 1022 data files, you have the same capacity
  Bigfile Tablespace and you can use several system files.

  To 80 GB with 3 or 4 data files, you can easily manage this volume. But of course from time to time you will have to
  Add a new data file.

  Hope this can help.
  Best regards

• How to increase the number of days before deleting messages in the trash?

  The automatic removal of e-mails to the trash is set for about 3 days. Much too short an e-mail should be necessary.

  In the left column of the files right click Trash. Select them properties. Click on the retention policy tab. Uncheck the box if it is enabled. Select the number of days you want to keep before deleting.

• Snapshots - how to save the State of the machine before deleting

  Hello

  We have a production VM on a cluster host ESXi5, which was taken earlier (nearly 2 years?). Of course, I want to get rid of the snapshot that he shouldn't have spent so long, and after some research, I'm pretty sure deletion will do what I want (I want to keep the virtual machine, as it is now with all the changes since the snapshot).

  However, I also want to take every possible precaution before to do this because if the changes are cancelled (i.e. if returned to the State of origin before the change), it will create a good amount of work, and I want to keep the virtual machine, as it is currently before deleting the shapshot.

  Is this possible? I read cloning will not clone the snapshot of the files themselves, but the cloned VM will contain changes since shapshot has created or will it be the VM before the snapshot? If the clone itself is a copy of the current computer running (changes since snapshot included), this could be an OK option.

  I don't think another solution could be to stop the VM and copy the VMWare real files somewhere - would this work?

  I am probably being a little cautious with this, but I'm a little nervous about snapshots and I want to make sure that I have all the bases covered... just in case...

  The virtual machine is saved so as a last resort I can restore from a backup, but I would rather avoid this path if possible.

  See you soon,.

  Tim

  This snapshot that one is associated with your virtual machine, which is 2 years old?

  what you think is right about removing it. If you just run this snapshot delete operation, it will merge delta with basic disk (since you instant is very ancient, the size of your delta is probably very much, in this case, this operation may take up very much time to complete) and resulting VM will be your last VM with all changes made after this snapshot was taken too.

  At the time of the snapshot, Deleting, you must also remember that there should be enough space available in your data store where you VM resides, if possible to reach downtime, then make the deletion of the snapshot while VM is powered off, or try opening the process during off-peak hours.

  I'm sure you might have encountered following KB already as you have done enough research on the topic

  VMware KB: Delete all snapshots and consolidate Snapshots feature FAQ

  I read cloning will not clone the snapshot of the files themselves, but the cloned VM will contain changes since shapshot has created or will it be the VM before the snapshot? If the clone itself is a copy of the current computer running (changes since snapshot included), this could be an OK option.

  Cloning will also do the job. Yes cloned VM will be for blocks of basic disk and disk from Delta and merger while then resulting VM cloning will be having only basic disc with all changes that you made after the snapshot.

  I don't think another solution could be to stop the VM and copy the VMWare real files somewhere - would this work?

  The virtual machine is saved so as a last resort I can restore from a backup, but I would rather avoid this path if possible.

  Keep copy of all the files in this virtual machine a safe, desirable for you, but at the same time if you have the frame of this virtual machine already successful backup made so nothing to worry. Your virtual machine can be restored from that successful return. If you want to test the restoration, why not restore you this virtual computer on an isolated network and not little a test for your complete satisfaction before proceeding to deletion of snapshot.

  Note: Do not operate upgraded, this will put your VM around 2 years back State at the time of the creation of the snapshot.

• How to insert statements before deleting

  Hello
  
  Here I have a certain requirement. I need to raise the rear of a table before that its data is deleted.
  
  Example of
  
  EMP table
  
  If I need to delete the deptno 20 data, before deleting, I need to take back of them as INSERT queries to the UNIX machine. could guide you please do this .i have heard that this can be done by package UTL_FILE. I don't know how to implement this
  
  Thank you

  Try something like...

  SQL> CREATE OR REPLACE PROCEDURE take_backup(pi_empno EMP.Empno%TYPE) IS
    2    v_file_handle UTL_FILE.file_type;
    3    v_file_name   VARCHAR2(500) := 'empbackup_' || pi_empno || '_' ||
    4                                   to_char(sysdate, 'ddmmyyyy') || '.txt';
    5    buffer        VARCHAR2(32767);
    6    emp_rec       EMP%ROWTYPE;
    7  BEGIN
    8    v_file_handle := UTL_FILE.fopen('TEST_DIR', v_file_name, 'W');
    9    buffer        := 'INSERT INTO EMP VALUES(';
   10    UTL_FILE.put_line(v_file_handle, buffer);
   11    SELECT * INTO emp_rec FROM EMP WHERE empno = pi_empno;
   12    /* Here I have NOT added all columns of the table. You should. */
   13    buffer := emp_rec.empno || ',' || '''' || emp_rec.ename || '''' || ',' ||
   14              emp_rec.deptno || ');';
   15    UTL_FILE.put_line(v_file_handle, buffer);
   16    UTL_FILE.fclose(v_file_handle);
   17  END;
   18  /
  
  Procedure created.
  
  SQL> EXECUTE take_backup(7369);
  
  PL/SQL procedure successfully completed.
  

  and the file content will be something like

  C:\Documents and Settings\Administrator>type C:\empbackup_7369_22092010.txt
  INSERT INTO EMP VALUES(
  7369,'SMITH',20);
  

  Now you can use this procedure in a trigger also according to your requirement.

• What is the best way to consolidate e-mail messages in the e-mail program, before deleting?

  I have an iMac with a capacity to 1.11 - 679,49 GB available. With the software updated.

  Model name: I

  ERGO: the question is...

  What is the best way to consolidate e-mail messages in the e-mail program, before deleting?

  (I hope I've inserted which may be useful, but I'm not sure about that.)

  Thank you

  ilenefrombaltimore

  Archive messages or move them to some other local mailboxes or mailboxes on the server. Don't know what you are trying to do because it appears that you have 2/3 of your hard disk.

  Why do you think archiving emails in 2 places? Where are you trying to save space to?

• 'Ask before deleting' Notes

  I installed 9.3.2 on my iPhone and was pleased to see that Notes is seeking more sophisticated - and there are some new features such as the addition of a drawing, etc.. But I accidentally hit the button Delete and then freaked out when he simply disappeared, just like that. I realize that there is a new "Recently deleted" folder, but prior to that, he is always asked to confirm if you want to delete a note. This instant deletion of a note as soon as your finger brushes the Trash button makes me really nervous. I don't understand why they would take away a feature like confirmation before deletion, which was previously available only to avoid situations where you don't even know that you have removed a note, because there is literally no notice before it disappears just; If you are not looking at your screen you never know it happened... and then after 30 days it is gone forever. As much as there is an option to turn the option "Ask before deleting" Mail, Contacts, calendars. Can we do not have the same option for Notes? Or at least just the do each time by default, just in case. Apple, please report it.

  Even if I am here, I am also disappointed that the new police force has reformatted all my notes so that the lists which have been made intentionally points of a line are now 2 lines, because the new policy takes more space; either because it is larger, or tracking or kerning is superior or something like that. Would be nice if we could adjust the font size and other options for fonts in the Notes.

  Thank you

  I agree with you!

• Send an email using mail my signature seems to drop before my email is considered by my beneficiaries. This does not happen all the time but often. Is anyone else know / encountered this problem? If, kind of help to rectify this please.

  Hi, when you send an email using the mail my signature seems to drop before my email is considered by my beneficiaries. This does not happen all the time but often. Is anyone else know / encountered this problem? If so help to rectify this would be greatly appreciated please. Thank you

  It is up to the recipient how their e-mail is displayed. For example, if you include html or an image in your email the recipient may set up their customer e-mail to not display html or images. You have no control over the way a recipient chooses configure their e-mail client.
