For this line, I need t1.col3 for choose later us

If I use select col3 from t1 after the its giving update all values for col3, but I want to only col3values lines updates only

You can use the return clause:

Wrote file afiedt.buf

  1  declare
  2    v_dummy number;
  3  begin
  4    update emp set sal = 0 where ename = 'KING'
  5    returning empno into v_dummy;
  6    dbms_output.put_line('Employee:'||v_dummy);
  7    rollback;
  8* end;
SQL> /

  • When you rename a file highlights only the name and not the name extension.

    Hi all

    When I rename a file, it highlights only the name part of the file name and not the name extension.  I need the name of entire file highlighted when I rename a file.  Where is the setting to change this?

    Thank you

    Pete

    Hi Pete,.

    Engineers also writes a blog on why they made this change, but to prevent millions of calls to support technical questions "I renamed my file and now it no longer opens.
    It might be possible to change this behavior with editing the registry, but I couldn't immediately find a reference to such a value.
    However, I have a workaround.  I usually press F2 to rename a file (I'm a lover of keyboard, hate having to use the mouse).  So I click on F2, then if I need to select both file extension, I can make one of these:
    • Press Ctrl-A
      or
    • Press SHIFT - end
    I generally use the method of shift - end because it's closer where my fingers are already on the keyboard (I'm a lover of keyboard, but I'm too lazy).  Hope this helps at least a little.

  • I accidentally created an email acct, how I remove to the newest one and not the former?

    Entally created an acct email, how do I remove to the newest one and not the former? And I get e just on the other.

    Play the 'e' (email?) to the old account first. You can drag and drop.

    To remove an account from Thunderbird:

    Tools | Account settings| < select the unwanted account > |

    Down at the bottom of the left pane, Account Actions , and then click remove account.

    Both accounts use POP? This could explain why new messages appear in the new account, but not the former.

  • HOW 'to LOCK"or close CERTAIN CELLS... and not the overall sheet

    "ROS" with Safari 9.0.1 and OS X EL Capitan 10.11.1

    I would like to "bolt" of certain cells, new should not be changed... and not the entire sheet...

    Possible or not?

    How?

    Thanks for help

    gymsclos

    You can lock an entire table, but not to individual cells in a table.  An effective way to organize your document would be to enter data in a table that is unlocked and have results of the calculations in a separate table that you lock to prevent accidental changes. You can have several tables on a single sheet.

    Check your message rules and see if you set up a message rule to shunt the in this folder.  It would be valuable to know what e-mail program, you are using and what version of Windows you have.  It is very difficult to give a useful answer when these information are not known.

    Go to file | Identities and establish a new identity.  Then add your e-mail account.  When this works, then use a file | Import messages to import from the old identity.

    Hi MichaelConner1,

    You can keep the individual mouse for each user account on the computer.

  • Can I shrink a logical drive and not the extended partition to a bare metal restore to a smaller drive?

    The current configuration is a Dell T310 with a S300 controller, with all locations 4 hot filled with SAS drives.  The operating system is SBS 2008 (2008 Server/Vista), I intend to change the controller of S300 (software) controller, a controller (hardware) H700.  My concern is that the H700 brings readers a little smaller in size.

    The typical arrangement of Dell's diagnosis, followed by a recovery partition partition (E :), followed by the system partition (C :), followed by a partition with a logical volume (d).  If I use Diskpart to shrink the D: 'partition', he let me with free space, not allocated.  Thus, it effectively reduces the logical drive, and the extended partition stays the same size as it was, with no way to reduce it.

    The question is, if I shrink the logical D: drive and not the extended partition and then get backups of the system, I'll be able to a bare metal restore on the smallest virtual disk of the H700?

    That's what I did:
    -Released the S300 controller and 4, 450 GB, 15 000 rpm Cheetah RAID-5
    -Replace the controller H700 and 2, 2 TB 7200 RPM in RAID-1 Constellations

    Results:
    -Eliminates the possibility of falling on a disk space issue when restoring
    -Increased the amount of available disk space.
    M ' left with 2 free hard drive for future expansion bays.

  • Start menu music link to my music and not the music library?

    Can I do the start menu links to music, documents and videos show my user folders for these items, rather than the folders in the library?
     
    Here is a picture to better understand: http://i.imgur.com/71Ro6.jpg

    I want to link the music to actually view the items in my music folder and not the folder 'my music '.

    He cannot do.  It can show the folder that then flies on to display the content when you hover over the name of the folder [XP-style].

    Just to make sure that we are not misunderstanding each other - set the start menu entry to be "Show in form of a menu" rather that "display as a link" on start, do a right click, properties, customize.
