• How do I know the size specific to a field in an oracle table

  Hello
  
  Oracle 11.2.0.3 on redhat
  I have three tables with the same structure, table0, table50, table100:
  
  create table table0 (ID options, shipping RAW (2000), RAW (2000));
  
  I inserted some 10000 lines each, but with a few differences:
  Table0 a 10000 id, but shipping and options has null values
  table50 has 10000 id, but shipping and options has only 5000 lines, the other 5000 are null values
  table100 has 10000 lines of id, shipping and options. No null values.
  
  I want to know the specific size of each column, also the size of each line, namely the exactly size of the field.
  
  for example:
  
  rank 1, the column of table100 options is "asdfasdfagasdgasbabsdgoasdpgiahnwe1129u412094u12".
  rank 2, the table100 column options is "a".
  both are given in raw format, but I think that its space will be a different size (bytes), how do you know? any question?
  
  I found this query:

  select owner,tablespace_name,segment_name,sum((bytes/1024/1024)) Bytes
  from sys.dba_extents
  where owner in 'MAA' and segment_type='TABLE' and segment_name ='TABLE00'
  group by tablespace_name,owner,segment_name
  order by owner,tablespace_name,segment_name, bytes; 

  but I think that is not my solution.

  If VSIZE returns a constant value, which allows to conclude that everything which is inserting the data in your table is always inserting a constant number of bytes.

  If I create a table with a RAW (1000) and insert data with different sizes of binary, VSIZE gives different results

  SQL> create table foo(
    2    col1 raw(1000)
    3  );
  
  Table created.
  
  SQL> insert into foo values( utl_raw.cast_from_number(12) );
  
  1 row created.
  
  SQL> insert into foo values( utl_i18n.string_to_raw('This could be a much longer string') );
  
  1 row created.
  
  SQL> select vsize(col1) from foo;
  
  VSIZE(COL1)
  -----------
            2
           34
  

  If you say VSIZE always returns the value 1000, which implies that everything what is the insertion of the data is always inserting 1000 bytes of data.

• How will I know the Creative Cloud Desktop app that an application no longer exists?

  I have installed Muse through the creative application of Cloud Desktop, tried, don't like it AND uninstalled it. (Or so I thought). However, the desktop application still shows CC Muse as "up-to-date" and lists the Muse CC 2014 in 'New versions available for applications installed'. How can I get rid of these, when I can't even find a trace of either on my Mac (including the new in Utilities folder)?

  Hello

  You can use CEIL(quarter_id/2)

• How to know the size of the files transferred to the SQL * Net?

  I'm testing the Advanced compress (AC) for 11 g Data Guard. When the AC is turned on, the archived log files are supposed to be compressed on the primary database server sent via SQL * Net, then unzipped on the standby db server. We will see that the file sizes are the same on the main servers and backup. I want to check that the AC works by monitoring how much data is sent via SQL * Net. By Oracle, AC uses less bandwidth of 35%. This means that the size of the transferred files must be at least 65% of the original size.
  
  
  Is there a way to know the size with the Oracle utilities? Otherwise, how do you know by the utilities of operating system? OS is Solaris 5.10.
  
  Thank you.

  I'm not sure that this can be done via SQL * Net, but a sniffer network between two servers packets must be able to help - you may want to contact your network team.

  How will I know if my magic keyboard is in charge? And how know when it is done load so I can unplug the charger of lightning?

  I remember reading that the charging time is about two hours.   If you have exhausted the battery it may well take longer.    After the period of two hours, he must run for about a month in any case if you could take the charger after 2 hours.    But I remember also as statements using the old MM1 mouse with rechargeable batteries Apple and stand-alone charger.    MIne has quickly reduced by about 14 days and now its down to 7 days.

• How will I know if my Airport Extreme has the latest firmware?  And (not related) how to change the password used to connect to my network?

  I think I bought the latest version of Airport Extreme.  It is the unit which is rectangular, is about 6 to 7 w., etc.  I have some basic questions that I do not understand:

  1. How will I know if I have the latest firmware for this device?  I read a few posts that make it sound as if it was just automatically updates.  Is this true?

  2. can someone tell me how to change the password used to connect to my wireless network?

  Thank you very much!

  If a firmware update is available, AirPort Extreme flashes orange.

  The most up-to-date version of the firmware is 7.7.3.

  You can see what version you currently have the following on your Mac...

  Open Finder > Applications > utilities > AirPort Utility

  Click on the image of the AirPort Extreme

  Look for the Version

  If the new firmware was available, you will see a button update here

  To change the wireless network password...

  Click on edit in the window smaller than you watched just to check the firmware version

  Click on the Wireless tab at the top of the next window

  Go back / change the wireless password and enter a new password

  Do the same thing to check

  Click Update at the bottom right of the window and give the airport a minute full for restart

  This week, I bought my laptop, and in the manual it says that some models of this series got pads dual rather than just a mouse pad. How will I know if my model is it?

  What I need to enable something, or would it just work automatically if it is on my laptop?

• How will I know if my mini ipod 4th generation is in charge? The blinking not solid.

  How will I know if my Mini Ipod 4th generation is in charge.

  I plugged it in - the blinking not solid.

  It's an iPod shuffle, right?  Small place with design clip - on and no screen...

  Blinking light means DO NOT DISCONNECT, because the iPod disk is mounted by the system.  EJECT iPod (in iTunes) before physically disconnect the iPod.  If you eject , but leave it connected, the light becomes solid.  (Yellow or green) light means OK TO DISCONNECT.  When it is yellow, the battery charge.  When it is green, the battery is fully charged.

  NOTE: In the normal conditions of use, flashing light is always yellow; It's supposed to be a warning.  It does not indicate the State of the battery; never it flashes green.
