• How to combine the large number of tables of pair key / value in a single table?

  I have a pair key / value tables of 250 + with the following features
  
  (1) keys are unique within a table but may or may not be unique in the set of tables
  (2) each table has about 2 million lines
  
  What is the best way to create a single table with all unique key-values of all these paintings? The following two queries work up to about 150 + tables
  

  with
    t1 as ( select 1 as key, 'a1' as val from dual union all
            select 2 as key, 'a1' as val from dual union all
            select 3 as key, 'a2' as val from dual )
  , t2 as ( select 2 as key, 'b1' as val from dual union all
            select 3 as key, 'b2' as val from dual union all
            select 4 as key, 'b3' as val from dual )
  , t3 as ( select 1 as key, 'c1' as val from dual union all
            select 3 as key, 'c1' as val from dual union all
            select 5 as key, 'c2' as val from dual )
  select coalesce(t1.key, t2.key, t3.key) as key
  ,      max(t1.val) as val1
  ,      max(t2.val) as val2
  ,      max(t3.val) as val3
  from t1
  full join t2 on ( t1.key = t2.key )
  full join t3 on ( t2.key = t3.key )
  group by coalesce(t1.key, t2.key, t3.key)
  /
  
  with
    master as ( select rownum as key from dual connect by level <= 5 )
  , t1 as ( select 1 as key, 'a1' as val from dual union all
            select 2 as key, 'a1' as val from dual union all
            select 3 as key, 'a2' as val from dual )
  , t2 as ( select 2 as key, 'b1' as val from dual union all
            select 3 as key, 'b2' as val from dual union all
            select 4 as key, 'b3' as val from dual )
  , t3 as ( select 1 as key, 'c1' as val from dual union all
            select 3 as key, 'c1' as val from dual union all
            select 5 as key, 'c2' as val from dual )
  select m.key as key
  ,      t1.val as val1
  ,      t2.val as val2
  ,      t3.val as val3
  from master m
  left join t1 on ( t1.key = m.key )
  left join t2 on ( t2.key = m.key )
  left join t3 on ( t3.key = m.key )
  /

  A couple of questions, then a possible solution.

  Why the hell you have 250 + tables pair key / value?

  Why the hell you want to group them in a table containing one row per key?

  You could do a pivot of all the tables, not part. something like:

  with
    t1 as ( select 1 as key, 'a1' as val from dual union all
            select 2 as key, 'a1' as val from dual union all
            select 3 as key, 'a2' as val from dual )
  , t2 as ( select 2 as key, 'b1' as val from dual union all
            select 3 as key, 'b2' as val from dual union all
            select 4 as key, 'b3' as val from dual )
  , t3 as ( select 1 as key, 'c1' as val from dual union all
            select 3 as key, 'c1' as val from dual union all
            select 5 as key, 'c2' as val from dual )
  select key, max(t1val), max(t2val), max(t3val)
  FROM (select key, val t1val, null t2val, null t3val
        from t1
        union all
        select key, null, val, null
        from t2
        union all
        select key, null, null, val
        from t3)
  group by key
  

  If you can do it in a single query, Union all 250 + tables, you don't need to worry about chaining or migration. It may be necessary to do this in a few passes, depending on the resources available on your server. If so, I would be inclined to first create the table, with a larger than normal free percent, making the first game as a right inset and other pass or past as a merger.

  Another solution might be to use the approach above, but limit the range of keys with each pass. So pass we would have a like predicate when the key between 1 and 10 in every branch of the union, pass 2 would have key between 11 and 20, etc. In this way, everything would be straight inserts.

  That said, I'm going back to my second question above, why the hell you want or need to do that? What is the company you want to solve. There could be a much better way to meet the requirement.

• Shape of the apex - how to get the primary key value manually?

  Hello
  
  Whenever I create form by using wizard Apex, he asks me to specify the trigger/sequence/pl/sql function to fill the primary key value.
  
  However, if I want to specify primary key myself (ie. undetermined generated automatically), how I can clarify that?
  
  Thanx

  Hello

  You mean by yourself: by hand or by a pl/sql?

  If you say by trigger, the system does not take on what number is sent. If you can give it "manually".

  May I ask what is the reason for this?

  See you soon,.

  Try the next method.

  Hold the left SHIFT key you click Shutdown to temporarily prevent hybrid boot.

  Let off the laptop computer for 10 seconds.

  Start by typing esc button permanently as soon as you press the power button (do not wait for the prompt) and see if it will access the start menu - if that is the case, select f10 to open the Bios Menu.

• How can I find the WEP key for my wireless network so that I can connect to it?

  How can I find the WEP key

  Steps to find a WEP key:

  1. open a browser (the program used to access the internet). The following process worked for me when using the

  Internet Explorer, Firefox and Opera browsers, although I'm not sure it will work for other browsers (for example

  Chrome, Safari etc.).

  2 type the following in the address bar of the browser. If you use a Linksys router type in "192.168.1.1" and if

  using a type of router Belkin "192.168.2.1". The address bar is the area where the Web pages are typed. It is important

  When you enter there is NO http://www. before the numbers.

  3. If everything is is well past that should open a page which says that Linksys or Belkin.

  3. There may be the need of connection. When you use a Linksys if you don't know what are the user name and password, it may

  always be the factory settings and then enter "admin" for the username and "password" for the password. If you are using a

  Belkin router, the factory settings often come without password, click just send without having to type a password.

  4. click on one) "wireless" or b) "settings".

  5. click one) "Wireless security" or b) "wireless settings".

  6. There should be a page with a specified WEP key.

  Hello

  If you are unable to retrieve the product key provided with the system then Windows communicate with the system
  Maker.

  Look at the lower/rear part computer and tape or disks that came with the unit.

  If the system is still running, you can use these to access your product key. These are not cracks, they
  only retrieve your existing key.

  One of them allows to recover your machine if possible.

  Can I get a configuration of single language somewhere? How can I find the license key for my installation.

  Hi Mohammed'metwally,.

  Please answer this question to get more clarity on this issue.

  • The application or program that you use the partition of the drive?

  This problem may occur if the partition table is damaged or altered. As a result, the recovery partition does not work. I'm sorry to know that you are facing this problem.

  You will not get the unique language anywhere to download setting. You have an OEM computer that comes with the product key integrated into the BIOS. The product key of Windows 8 on new machines is now integrated in the machine. It uses the Secure Boot technology. When you perform a new installation of Windows 8, the installation program ask a product key and will be automatically get it from your system and proceed with the installation.

  As Windows 8 came pre-installed, you must contact the manufacturer of the computer with this problem for more help.
