• recursive query with two tables

  Hello
  
  Im having problems of recursive query construction and add to select the list to see the result in hierarchical mode, so I want to your advice.
  
  I have two tables:

  TABLE: t1 
  c_id       parent_id      c_level
  1              -                 1
  2              1                 2
  3              1                 2
  4              -                 1
  5              4                 2
  6              5                 3
  
  TABLE: t2 
  c_id         c_name
  1               name1
  2               name2
  3               name3
  4               name4
  5               name5
  6               name6

  And I want to see the result like this:
  
  -Name1
  -name2
  -Name3
  -Name4
  -Name5
  -name6
  
  Could you please help me with this?
  Or maybe can you provide good links where I can find solution how to SELECT LIST looks like the hierarchical tree?

  Here is my test scenario:

  CREATE TABLE t1(
    c_id      NUMBER,
    parent_id NUMBER,
    c_level   NUMBER);
  
  CREATE TABLE t2(
    c_id   NUMBER,
    c_name VARCHAR2(10));
  
  INSERT INTO t1 VALUEs(1,NULL,1);
  INSERT INTO t1 VALUEs(2,1,   2);
  INSERT INTO t1 VALUEs(3,1,   2);
  INSERT INTO t1 VALUEs(4,NULL,1);
  INSERT INTO t1 VALUEs(5,4,   2);
  INSERT INTO t1 VALUEs(6,5,   3);
  
  INSERT INTO t2 VALUEs(1,'name1');
  INSERT INTO t2 VALUEs(2,'name2');
  INSERT INTO t2 VALUEs(3,'name3');
  INSERT INTO t2 VALUEs(4,'name4');
  INSERT INTO t2 VALUEs(5,'name5');
  INSERT INTO t2 VALUEs(6,'name6');
  
  SELECT LPAD('-',2 * a.c_level,'-') || b.c_name the_tree
    FROM t1 a,
         t2 b
   WHERE b.c_id = a.c_id
  CONNECT BY a.parent_id = PRIOR a.c_id
   START WITH a.parent_id IS NULL;
  

  and the result:

  THE_TREE
  ----------
  --name1
  ----name2
  ----name3
  --name4
  ----name5
  ------name6
  

  I took the example you gave then perhaps your largest data set has the flaw?

• How to create a recovery disc with all vista updates?

  original title: how to create a recovery disc with all vista updates without starting from scratch, so I can replace my hard drive?

  My hard drive seems to be dying.  I would replace the drive.  I reloaded vista from scratch with all the updates, but it took forever.  I would like to make a record of recovery with all updates.  IAM on vista Home premium.  32 bit

  If you want a good backup program that backups image, I recommend Acronis True Image 2010:http://www.acronis.com/homecomputing/products/trueimage/.  It offers a free trial, so you can test and if you want it's only about $30 for the original version.  A lot of people I know this program and use it instead of Vista even in versions of Vista that offers imagery as this program does a better job.  Of course you also need a place to put the backup (which will take a lot of space), so also consider.  The best choice would be a USB external hard drive at least as large as the readers you want to back up (not only the data on them, but the entire available disk space, so you miss when you add more information about the disks).

  You cannot use IMGBURN do - it can't do anything like that.  It must be the imagery of backup software.

  I hope this helps.

  Good luck!

• How to create a tabular report with alphabetical link at the top

  Hello
  
  I have a db of the users table and have created a report based on this table, but I want that each letter of the alphabet at the top of the report so that users can click on the letter and see all the records where the username field begins with that letter.
  
  How can I achieve this?
  
  Thank you

  Hello user11243298 (please tell us your name).

  Your report query might look like this (assuming that the page number is 1):

  Select some_column1, some_column2
  of your_user_table
  where username as: P1_INITIAL | '%'

  For the letters at the top of the report, here are some options:

  -If you want that all the letters to appear or not lines, you can create a series of buttons or links, one for each letter and specify the target URL make return to the report page, defining the P1_INITIAL element to each letter.

  -If you want only the letters which were stored, is to create a dynamic LOV based on a query like this:

  Select distinct superior (substr (username, 1, 1)) d, high separate v (substr (username, 1, 1))
  of your_user_table
  order from the top (substr (username, 1, 1))

  Can use it for a list of selection with submit, again targeting the report page and the P1_INITIAL parameter to the selected value.

  Hope this helps (if this is the case, please reward it),.

• How to create a view in the DB table for some servers

  Hello
  
  We need create a country table which will contain data for countries.
  
  I want to create it in such a way that it will be common for all servers - but as a point of view. not the real table, only the data and views do not change.
  
  How can I do?
  
  Thanks in advance

  Are you sure you want to say 'tablespace '? A tablespace is a collection of data files. It has nothing to do with the privileges of the object, object namespaces, etc. I'm guessing that you mean that you have two schemas, OBITUARIESCS and ADVERTISEMENTCS. A schema is a collection of objects of database belonged to a particular user. A single table can exist in spaces of multiple tables (assuming it is partitioned). Different schemas can have an infinite number of tables with the same name in the same table. The database schema is the namespace for objects such as tables.

  Assuming that you have two schemas in your database, you can create a table of COUNTRIES in the OBITUARIESCS schema. You can then grant SELECT access on the table to another user, ADVERTISEMENTCS, i.e.

  GRANT SELECT ON country TO advertisementcs
  

  You can then ask questions (but not change) the COUNTRY code of the property of ADVERTISEMENTCS table

  SELECT *
    FROM advertisementcs.country
  

  If you want to be able to remove the prefix in the schema, you can create a synonym. In the ADVERTISEMENTCS schema

  CREATE SYNONYM country
    FOR advertisementcs.country
  

  and then when the code of the property of ADVERTISEMENTCS wants to query the countries table, it can just

  SELECT *
    FROM country

• I have a column with two values, separated by a space, in each line. How to create 2 new columns with the first value in a column, and the second value in another column?

  I have a column with two values, separated by a space, in each line. How do I create 2 new columns with the first value in one column and the second value in another column?

  Add two new columns after than the original with space separated values column.

  

  Select cell B1 and type (or copy and paste it here) the formula:

  = IF (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  shortcut for this is:

  B1 = if (Len (a1) > 0, LEFT (A1, FIND ("", A1) −1), ' ')

  C1 = if (Len (a1) > 0, Member SUBSTITUTE (A1, B1 & "", ""), "")

  or

  the formula of the C1 could also be:

  = IF (Len (a1) > 0, RIGHT (A1, LEN (A1) −FIND ("", A1)), "")

  Select cells B1 and C1, copy

  Select cells B1 at the end of the C column, paste

• Satellite P840: How to create the secure boot with UEFI Bios recovery disk

  Hello

  I have laptop P840 that came pre-installed with Windows 8, which I've upgraded to Windows 8 Pro.
  I then updated to Windows Pro 8.1 by Windows store. Please notify:

  1. how to create a DVD repair or start for windows 8.1 pro with UEFI Bios and boot secured.

  2. I created a USB recovery using the control panel in Windows Pro 8.1. It starts OK. It will be the same as that I've created using the Toshiba Media recovery creator or will it drivers Windows Pro 8.1?

  3. check partitions with disk management, then 3 (450MO, 350 MB and GB 10.90) recovery partitions, 1 EFI system partition and 2 primary (C: programs) and D: for data. I created the recovery DVD and USB 2 disks. Can I remove the 3 recovery partitions?

  Your help will be very appreciated.

  > 1. How to create a DVD repair or start for windows 8.1 pro with UEFI Bios and boot secured.
  To be able to boot from sources other than the drive HARD internal, the boot mode must be set to the CSM and secure boot must be disabled!

  > 2. I created a USB recovery using the control panel in Windows Pro 8.1. It starts OK. It will be the same as that I've created using the Toshiba Media recovery creator or will it drivers Windows Pro 8.1?

  Your laptop has been preloaded with Win 8. Right? For example, the USB flash stick memory you just use the Toshiba Recovery media creator contains the Image of Toshiba with Windows 8. Don t mix this Toshiba image with the image that can be created using Microsoft's own backup and restore function. Both are different pictures!

  > 3. Check it with disk management, then 3 (450MO, 350 MB and GB 10.90) recovery partitions, 1 EFI system partition and 2 partitions primary (C: programs) and D: for data. I created the recovery DVD and USB 2 disks. Can I remove the 3 recovery partitions?

  The last partition contains the files on HARD drive recovery. Usually this partition will be created again when you use the Toshiba Recovery disk to put the laptop back to factory settings. So in the case where you n t need this files or the partition, you can delete

• How to create the energy bar with flash pro?

  Hello

  How to create an energy bar as what you see in flash facebook games, which increases with time "as every minute add 1 energy point' and reduce playing a role or a battle or just do an action?

  You can simply use a rectangular moviweclip/sprite and use Actionscript to control the width (or height), where the energy is proportional to the value of the width (or height).  You can also pair with a textfield that allows you to display the actual value of energy as it changes.
