• Change the default value of column NOT NULL to NULL

  Hi all
  How can I change the default value of column not NULL to NULL?
  Suppose I have run the following commands:

  SQL> alter table hr.test modify temp_num2 default null;
  
  Table altered.
  
  SQL> desc hr.test;
   Name                            Null?    Type
   ----------------------------------------- -------- ----------------------------
   TEMP_NUM                             NUMBER
   TEMP_NUM2                       NOT NULL NUMBER

  Why forced temp_num2 has not changed with the NULL value? I'm under 11.g rel2
  
  Best regards
  Valerie

  You can NOT change the column constraint NULL to contain NULL values by:

  alter table table_name modify column_name null; 
  

  After this change, the column can contain null values. In Oracle, not null constraints are created automatically when not null is specified for a column. Similarly, they are deleted automatically when the column is changed to allow NULL values.

• Change the default value for new messages of the 'paragraph' in "text" format the answer currently online because it does not work

  The answer currently online for this problem said to follow the sequence "tools-options-composition" and then change the default value, but this sequence "tools-options-composition" does not exist in Thunderbird (at least in the version I have, 45.4.0). Under 'tools', there is no option 'options... '

  It can depend on what menu you look and which operating system you are using.

  Tools | Options | Composition refers to the menu bar on top old.

  You can use alt or F10 to make the menu appear temporarily. Go to the view of . Toolbars and check the boxes if you want it constantly on the show.

  If you use the button 'Menu of the Application' new fashion (with three horizontal lines - see the attached picture) then it's probably Options | Options | Composition -I say 'probably' because I'm on Linux where 'Options' are replaced, I think that, by "Preferences". Another complication with this infernal Application Menu is that different things happen depending on whether you click or hover. Place the cursor on the Options of the first and the second appears after some time.

  See http://kb.mozillazine.org/Menu_differences_in_Windows, _Linux, _and_Mac of the differences in Windows, Mac and Linux menus.

• You can change the default values for shape layers?

  Specifically, I want the default paths Trim "connect multiple traces' '' individually '' and default STROKE line Cap and line join defined respectively on"Round cap"and"join Round '.

  I know that I can copy and paste these properties also but I wonder on changing the default settings - perhaps in a preferences file? Thank you

  No, there is no way to change the default values. If you have a set of properties that you always want to use, you can save them as a preset.

• How to change the default value of a parameter and LOV attached to a parameter

  Hi all
  
  I'm new to the discoverer reports and I need the following tasks:
  1. the need to change the SQL of a discoverer report
  2. need to change the default value of the parameter (from constant for the current month). In the discoverer more responsibility when I open the report and go to tools > > setting > > edit
  I can see the value of the default constant is given. On the right side there is a drop down that says "Value". I suppose that if I put a SQL as default, I need to change the drop-down list for sql or something and then put the code SQL. Problem is the menu drop-down is froezen and I can't change it.
  Even if I try to create a new report parameter.
  3 need to change the LOV associated with the element on which is based the setting.
  
  
  I have the discoverer more responsibility to myself and did not have the discoverer administrator (as forms 6i developer desktop tool) tool. My questions are:
  1. can I modify the SQL query using discoverer and responsibility or do I discoverer Administrator tool?
  2. any help on how to get the default value of an SQL query? Currently, it is a constant value.
  3. is there a way to understand is that the LOV is made of the constant values fixed (as a set of values independednt) or they are read in a SQL (value valid table sets)?
  
  Solutions pointers will be greatly appreciated!
  Thanks in advance.
  
  Thank you and best regards,

  Yes, it is possible. But what is your version of the database? Try to use "virtual column. Search for a virtual column in the following link.

  Gouri,

  You can change simply to attribute each report column. For example,.

  To set the default date.
  Default type: PL/SQL Expression of function
  Default: sysdate

  To set the default text,
  Default type: PL/SQL Expression of function
  Default: * "CLERK."

  If you still get an error, what is the error message?

• change the default values of a secondary vi

  I want to initialize multiple devices connected via gpib using several secondary school (one for each device). Each type of device (temperature monitor, meter) has its own sub - VI (or better a vi model) for the configuration. The Subvi takes an address gpib only as a parameter. The vi is loaded in the secondary, the user is able to change the configuration via the controls on the front panel. Then he pulls the "init" button and the vi is executed (which writes the data to the front of the device).

  Currently, these config vi charge their default values for the file vi itself (current brand of default values). Is it possible to change this default value before running the Subvi, without losing flexibility?

  
  

• I can't have my Subvi simply use the default values for some of its entries?

  I use the code for a DS345 machine, using the sample code from here: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9149659CE034080020E748...

  I use version 7.0 (because I'm in 7.1).

  Anyway. I managed to get the proper waveform I wanted, just stored waveform in the default values and frequency input, so I can some frequency I want input. When I run the example VI itself, it displays the waveform for the machine just that very well, however, when I use this example VI as a Subvi, it didn't come out of the machine data.

  Any ideas?

  Thank you

  Edit:

  When I say defaults for some of its entries, I mean the values that are usually connected by a user, controls that are not 'inputs' in VI.

  I understood the question, and I must say that I am embarrassed. If you look at the code, I'm feeding a resource VISA name, when the Subvi needs just a chain with the GPIB address number.

• How to change the default value of MS Paint record - an output to jpg for shortcuts KEYBOARD: Alt-F-A (or S)?

  I've seen a lot of posts on this subject here, but they are all on the use of the mouse and I did not yet find one with an answer to MY specific dilemma.

  I take screenshots and edit photos (Nothing fancy) almost every day. Given that my physical disability in my arms causing me pain and discomfort when I use the mouse, I need to use several shortcuts as humanly possible help reduce the constant pain, I'm still in my right arm using the mouse.

  I *need* to know how to change the default hotkey Alt-F-A (or S) to save it as a JPG file relative to the current default value PNG which I use never, never. If it requires editing the registry, no problem, just point me in the right direction and guide me on how to do it.

  Thank you

• Permanantly disabling "Install Google Toolbar" and change the default value for future updates

  I use Adobe products for years and, in general, is that Adobe produces some really useful tools for users of computers and productivity.  Thereby, ever time I get notice of an 'Adobe Flash Player' update I have to answer the same questions during the update / install process.  During the installation of the installation application ask if I want to install the toolbar 'Google', and the default value is Yes, then I have to uncheck the box before installation or I receive the software on my system I do not want or do not want.  In addition, towards the end of the update, the installation application provides three options on future updates:

  (1) download and install automatically

  (2) ask before installing

  (3) never install...

  And each installation I have to uncheck the installation of "Google Toolbar" and tell them that Adobe 'ask me... ' "before you download and install future updates.

  Is it possible permanently disable toolbar Google and by default my response to the update download and install question to always be 'Ask Me' first?  Adobe's witnesses crossing the machine during this process, so please do not suggest that it is not possible.  Adobe simply needs to modify the setup package to find these cookies and apply preferences users for the installation process instead of constantly trying to push unwanted applications and choices to the user.

  The displayed offers are based on the OS and the browser used.  If the two of you are essentially correct, for the browsers you use.

  If you opt in background updates, update option = allow Adobe to install updates (recommended), Flash Player will be updated within 24 hours of a new version is released.  If you use several browsers that use different types of Flash Player (for example, IE & Firefox) all drive types are updated within 24 hours of the new versions available.

  If you opt in notification updates, update = option Notify me when updates are available, the update notification generally appears within 7 days of an update is available and it is after that the system was restarted or that you log on/off voltage.   Opting to put up-to-date will launch the browser to a download page to download and install Flash Player.  If you use several browsers that use different types of Flash Player (for example, IE & Firefox) as the type of player who set the notification of update is updated.  The other type of player is not updated.

  Essentially, opting in the background updates will update all types of drive on the system within 24 hours and avoids downloading accidentally offers from third-party vendors.

  Note: there are slight differences for OS X updated behaivour but since you have Windows I described the behavior under Windows.
