  If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.

  n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.
  
  This insistence is intended? If not, IMO, it should be changed.

  Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

  When you add a column, the initial value of each row in the new column is null.

  * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

  This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

  * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

  Hope that helps to clarify the matter further.

  Kind regards

• Insert with the default

• [8i &amp; 10g XE] How to compare a column with the text of a column with numbers

  This is probably a simple question, but I can't seem to find the answer. I tried variations on use to_number to_char and interpreters, all nothing will do.
  
  The real problem is that I have a table with a column of numbers in a database 8i (datatype = NUMBER (3)) and a column with the text (datatype = CHAR (3)), and I need to compare two values.
  
  This table has thousands of lines, but here's an example of the data in these two columns:

  TXT     CHR
  -----------
  001     1
  001     2
  002     2
  XXX     1
  003     3

  What I want to do is select the lines where the TXT and CHR VALUES do not match, then it would be (given my example):

  TXT     CHR
  -----------
  001     2
  XXX     1

  But, I'm having difficulties in comparing two columns, because they are not the same type of data.
  
  I tried to work on a simplified version of the problem in the 8i database both my 10g XE database:

  SELECT     *
  FROM     (
       SELECT     1.000               AS nbr
       ,     TO_CHAR(1.000,'000')     AS txt
       ,     CAST('001' AS CHAR(3))     AS chr
       FROM     dual
       )
  WHERE     txt = chr
  ;

  But this also returns any line, and it isn't even the "XXX" in the text column to treat in this example.
  
  Can someone help me understand what it is that I'm missing?
  
  Thank you!

  ;
  

  Try:

  TO_CHAR (1.000, 'FM000')
  

  By default, TO_CHAR leaves place the beginning of the string to a sign less, in which case he should ever one, TO_CHAR (1,000, '000') returns makes 4 characters, not 3. "FM" in the format said TO_CHAR do not add a space.

  If it does not, after the release of DUMP (txt) for the few lines that you can't match, so that we can see exactly what is in them.

  you will need to update the CHGDATE column with the time of the CHGTIME column.

  Sorry, we need a new format around the to_date

  select to_date(to_char(chgdate, 'mm/dd/yyyy') || ' ' || to_char(chgtime, 'hh24:mi:ss'), 'mm/dd/yyyy hh24:mi:ss') from etime3;
  

  This should telll Oracle to the format of the generated string. If this isn't the case, run select with the to_char two as separate columns to see that get us the data that we expect.

• CHKDSK incorrectly replacing invalid security with the default id id

  the last 2 times I had to restart after installing an update windows CHKDSK destroyed my computer when chkdsk incorrectly replacing invalid security with the default id id.  OUCH!

  Whenever I roboot now CHKDSK can go and I don't want to lose my computer time a third and having to reinstall everything again.

  Is there some kind of fix for this?

  I have Windows Vista Ultimate SP2

  Hello JimHarding,

  Response by Sebastien will disable chkdsk to run at startup.

  My concern here is that even after a format and clean install, chkdsk keeps is triggered to run.

  This could be a sign that the hard drive begins to run out.  It is my recommendation that you begin to take a very up-to-date backup of your data very convenient where the disc goes down.

• Windows 7 crashes my profile, leaving me with the "default" profile. Even if I wipe my laptop and re-install.

  Hello

  First: I have two identical laptops purchased from Dell with the same hardware configuration - both delivered with Vista. I upgraded to W7 as soon as possible, and since then, one of the laptops does not load my profile several times.

  I use to work as a system administrator, so of course, at the beginning, I didn't much attention to the mistake thinking it was just an incident. I formatted the computer, reinstall W7 and, of course, the error occurred again - constantly even if I wiped it and re-install.

  What is happening is that the computer starts, I connect Windows crashes for the moment very loong and then all of a sudden he says "preparing your desktop". When that happens I know its load under the 'default user profile', it's 'welcome '.

  This error occurs about two to three times in about 7 days. But not all the time - it's like periods. I usually get through this by organizing the closure for 4 seconds, restart, and then, if I'm lucky, gets through my office.

  A few times that I had no chance - restart of 6 times in a row without luck somehow shows that the profile files are really damaged, and then I created a new migration profile all my old files. This process takes time - not simply copy my files but also the settings of my program.

  Last week, I deleted my user just to create a new one-8 it recharges without success.

  I looked in eventvwr.msc and found that everything begins with six fouls in a row. I don't really know what do - the error log says error but it seems not very well describe it.

  It goes like:

  1 error:

  Windows could not load the registry. This problem is often caused by insufficient security rights or insufficient memory.

  error 5 (a warning):

  RETAIL - only part of a query ReadProcessMemory or WriteProcessMemory was completed.
  EVENTID: 1505
  TIMESTAMP: 2010-12-30 10:03:48

  I don't know what it is. I can only say that reinstall W7 does not help. And lately, after creating the new profile, W7 began to start the default new desktop computer.

  So my question is: can I fix? If its not repairable can at least save files like ntuser.dat to crush the ntuser.dat file damaged W7 start sleeping?

  Software properly written (as opposed to malware, viruses, and poorly written stuff) has similarly on day 1 after installation on 30 days. So you can go ahead with your driver and software installation as fast as you want, as long as you create a new file image at strategic points and keep notes dates when you installed this component.

  Given your experience, you will need to proceed cautiously with the automatic updates. First disable them, and then put the installation in Manual Mode so that you can install in small batches, again take notes.

  If you use Acronis image to create images, then you will need only half of space compared to the native tool. And if divide you your drive and put your personal files on the D: drive then you will not lose them during a restoration of the image.

• Querying the oracle table that has a column with the name of "FILE".

  Hi all

  I need to have an oracle table that has the column with the name "FILE".

  I can query all columns with the query "select * from table".

  But I'm not able to use the query "select the table file.

  This table is converted from ms access to oracle and I need to have this column with the name "FILE".

  Any suggestions?

  Thank you

  Hello

  FILE is a keyword from Oracle, so it's not a good name,

  Use FILEDATE, or DATE_FILED, or something else that is not in V$ RESERVED_WORDS. KEYWORD as the name column.

  If you need to use the FILE, then you must use quotation marks.

• When I select a local adjustment, how can I scroll the new adjustment panel with the default panels

  In lightroom in the develop module. When I select a local adjustment for example the Brush tool or the gradient tool, the adjustment of the particular tool panel appears in the sidebar where I can make adjustments to these tools (see figure below).

  
  

  Now my question is with this adjustment Panel, it seems to be coming overlap on top the other default settings (for example the "base Panel" - exposure, contrast etc) and when I scroll down on other settings, the Brush tool or the gradient tool adjustment panel is always on top and does not scroll with the default settings.

  
  

  I would like to change the setting of this kind that the adjustment panel is part of the other default settings in the module development and scrolls with them.

  I know this is possible because I saw online videos where this is the case, and my lightroom on another machine for this.
  If anyone know how I change the setting for this?
  
  
  

  
  

  It seems to depend on the actual size of the Lightroom window. Just messing around with the CRD and LR5 onto my retina MBP 15 "with a monitor 1920 x 1200 and the two Lightroom versions scrolls happily adjustments table so that others, but only if the size (i.e. the height) of the Lightroom window is below a certain level. Done on the screen retina, when the display is set to 'Better for the retina', the Panel scrolls with others. But if I change the screen resolution of 2880 native and expand the LR window to fit, then the settings panel does not scroll.

  Similarly, if I move LR for the monitor external, same thing, i.e. Panel does NOT scroll when the window to maximize LR, but it does not scroll when I lower the height of the LR window (seems to be around the mark 1600 pixels)

  It's the same with LR5 and even on the Windows platform. I think he has somehow based on the height of the Panel adjustments with regard to the total height of the LR window, i.e. the settings panel does not scroll when there is enough space in the right panel to allow the eyes of one or many of the other tools below.
