• 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.

• After the replacement of my iPhone screen 6, front facing camera does not work.

  After the replacement of my iPhone screen 6, front facing camera does not work. The rear camera works fine, but when I switch to selfie cam I saw a still image of what was on the camera back; and on snapchat it simply refuses to move to selfie cam. I check to make sure that all connectors are deep-set. Any suggestions?

  If someone else that Apple will replace your screen they screwed up. If Apple has replaced your take screen back to the store.

• Music and ads are ok. Videos with speaking parts (last tested on the episode of Letterman with Tina Fey as a guest) does not work.

  Hi, I have Windows 7 and the Sound Blaster Recon 3D PCIe audio device. In the last few weeks, I noticed that some videos will play without problem and some have the following problem: the music and ads are ok. Videos with speaking parts (last tested on the episode of Letterman with Tina Fey as a guest) does not work well. Specifically, I hear a noise when they speak. But if I keep place the volume of the speaker (on the icon) and keep clicking the open icon, the sound begins to get stronger and you can actually hear it above his ' ding ding ' by clicking on the icon of the speaker volume. I've never had this happen before. I don't think I did something different from my usual activities lately and haven't downloaded all new program. Music plays without problem. Only the French-speaking parties. I tried the program compatibility troubleshoot and it told me "Incompatible application". Don't know what it means that I am aware of no incompatibility. Never happened before. Just suddenly appeared. Don't know if updates recent MS interfered with the audio device.  Also, I tried looking for questions that are already using the Control Panel, Manager of devices... and no problems were discovered. I put the volume on the strongest settings already and that doesn't work anymore.

  Thanks for your help to solve this problem.

  Just an update.  Problem solved. Faulty speaker connections. Did not touch the connections before the problem, so not sure what happened to these connections, but the problem is resolved. Thank you.

  Hi Yanni,

  Tethered shooting works fine with Lightroom 6.4 on El Capitan.

  You can then go ahead and buy Lightroom and perform the tethered shooting.

• Packer of creative cloud in creating a package that I can install do not.  He goes through the motions, download all updates, create setup file, but it does not work despite the fact that there are no errors in the log files

  Packer of creative cloud in creating a package that I can install do not.  He goes through the motions, download all updates, create setup file, but it does not work despite the fact that there are no errors in the log files

  After hitting my head against the desk to repeatedly create packages, try on different computers I have finally found a solution.

  These packages have been copied on an external drive, if I try and install from the external drive, which is a common practice, it fails.

  If I then copy this file pkg from the outside, to the computer I install, then run it, it will to and moved very well.

  That is mind-boggling stupid, because it's rare that you have to copy the file into any computer, it is less always installed off the coast of externally, and many people in the company are pushing on the network and the management of the suites so there is a serious problem in Adobe package manager if this is the case where it cannot manage the Middle installed offshore.

  I hope that if anyone else is having problems so it suits.

• Satellite X 200-slot for flash card does not work

  Hi, I got a Toshiba Satellite X 200 23 P with Vista.
  my flash memory card slot does not work, I use an SD card that I've used a few months ago and it worked well.
  When I put the card, nothing happens.

  Help, please.
  Thank you

  You see the SD card in disk management?

  Do you have the yellow marks in Device Manager? Maybe you should also update the card reader driver. A newer version, you can find on the European site of Toshiba.

  In addition, you should test another SD card. The card is maybe defective.

• Made the switch from the Firefox chrome; now, meeting places and a few videos does not work

  Salvation; I'm wanting to get away from chrome, but in firefox, I can't get the 'hangouts' working in gmail, even if I do not have the googletalkplugin installed on my pc. Another issue I see is that, on some pages, video does not work; in the latest version of chrome, I understand that the flash thing has changed and I guess that firefox has not changed in the same way. I hesitated when downloading a plugin, as shown on the screenshot for fear that it will mess up video in chrome, I would use chrome. I would rather not switch back from firefox to chrome to phone or watch the video. Help, please.

  I asked for help on the hangouts thing before, but your suggestion 'install plugin' was not enough, so I request further assistance on this now. on the video thing, please just tell if I should download the plugin and whether or not it will affect the reading in chrome. Thank you

  Working! I had the talk plugin set to always turn on but I had disabled the video because I only use the phone, but apparently, they both need to be addressed to always activate... Please mark this as resolved and thank you!

• I upgraded to latest version firefox 29,0 in windows machine 7. All the user interface looks very good. Undo close tab does not work for me. Is that not been addressed?

  You can try to start Firefox in Mode safe to see if Firefox works correctly without error? You can start Firefox in Mode safe below:

  • Windows/Mac: choose Help > restart with disabled modules
  • Linux: run firefox-safe-mode in the Terminal/Konsole

  If Firefox opens fine with no problems, it is probably one of your extensions that is causing the problem. You can reactivate your modules one by one until you find the one that is causing the problem to be re-activated.

  I tried to "update drivers" for my CanoScan LiDE 200 just in case, but he said that all drivers are already updated. But when I press "scan" on my scanner, it nothing happens; It does not work! I went to "scan profiles", through the "Scanners" Wizard and when I tried to add my scanner, he said:

  Error - Failed to initialize selected scanner.
  What should I do? I need my scanner!
  Thank you.

  You need to install the win7 Canon software / drivers before you connect the scanner
