• How to create indexes on the nested table.

  Hi all
  I held the syntax to create indexes on the nested table.
  
  I found below synta but when I try it with my table it gives me error
  
  CREATE UNIQUE INDEX indx_name
  ON nestedtablestore (NESTED_TABLE_ID, id);
  
  What is here NESTED_TABLE_ID & ID

  They are virtual your nested table

  Here is an example.

  create or replace type obj as object (no integer, address varchar2(100))
  /
  create or replace type tbl as table of obj
  /
  create table test_tbl (id integer, name varchar2(100), address tbl) nested table address store as address_nt
  /
  create unique index address_no_idx on address_nt (no, address)
  /

• Use two temporary tables to assign 'color' to the results of the data

  Hello world... Here's what I'm trying to do, any help is appreciated of course...
  
  Data and Tables in the example:
  
  I have 5 dishes, each course has 2 assignments.
  

  with Courses as (
   select 100 courseID from dual union all
   select 200 from dual union all
   select 300 from dual union all
   select 400 from dual union all
   select 500 from dual
  ), Assigns as (
   select 'test100' name, 100 courseID from dual union all
   select 'test100', 100 from dual union all
   select 'test200', 200 from dual union all
   select 'test200', 200 from dual union all
   select 'test300', 300 from dual union all
   select 'test300', 300 from dual union all
   select 'test400', 400 from dual union all
   select 'test400', 400 from dual union all
   select 'test500', 500 from dual union all
   select 'test500', 500 from dual
  )
  select assigns.name, assigns.courseID from courses
  inner join assigns on assigns.courseID = courses.courseID

  I need each assignment to get a color assigned to it according to its courseID. So my theory is that I have a temporary table with a list of colors; each courseID would be are they assigned a color, but my question is how can I assign each courseID a color without anything to join the temporary table? Once that each courseID has a color, I would join rights holders so that each assignment has a color associated with it according to its courseID.
  

  --Color table with 6 colors
  with Colors as (
   select 'red' color from dual union all
   select 'blue' from dual union all
   select 'yellow' from dual union all
   select 'green' from dual union all
   select 'purple' from dual union all
   select 'teal' from dual
  )

  I have a previous post on this topic, but I didn't do well explain and make a link to it would probably add to the confusion to this question... happy to delete this post if someone recommends.
  
  Thanks for any help! Running Oracle 11 g.

  I don't have the ability to store the courseID with colors...

  Can get it, or ask someone with the makeup of capacity change for you.

  Is the problem that you have more than 6 courses but you want to add color to them with only 6 colors, and it is unclear what courses can be included in the results of a given query?
  If so, you can do somehting like this:

  WITH     colors     AS
  (
       SELECT  'red' AS color_name     FROM dual UNION ALL
       SELECT  'blue'                FROM dual UNION ALL
       SELECT      'yellow'          FROM dual UNION ALL
       SELECT     'green'               FROM dual UNION ALL
       SELECT  'purple'          FROM dual UNION ALL
       SELECT     'teal'                FROM dual
  )
  ,     colors_plus     AS
  (
       SELECT     color_name
       ,     ROW_NUMBER () OVER (ORDER BY NULL) - 1     AS color_id
       ,     COUNT (*)     OVER ()                    AS color_cnt
       FROM     colors
  )
  ,     course_assigns     AS
  (
       SELECT  a.name
       ,     a.courseid
       ,     DENSE_RANK () OVER (ORDER BY  a.courseid)     AS course_num
       FROM          assigns          a
       INNER JOIN      courses      c     ON   a.courseid   = c.courseid     -- If needed
  )
  SELECT     ca.name
  ,     ca.courseid
  ,     cp.color_name
  FROM     course_assigns  ca
  JOIN     colors_plus       cp  ON   cp.color_id  = MOD ( ca.course_num
                                               , cp.color_cnt
                                    )
  ;
  

  Typical power:

  AME      COURSEID COLOR_
  ------- ---------- ------
  test100        100 blue
  test100        100 blue
  test200        200 yellow
  test200        200 yellow
  test300        300 green
  test300        300 green
  test400        400 purple
  test400        400 purple
  test500        500 teal
  test500        500 teal
  

  It would be better if you could create a real table as colors_plus.

  If there are more than 6 separate courses in the output, then 2 or more courses can be coded in the same color, but no color will be used N times (N > 1) until all the colors have been used N-1 times.
  The assignment of courses coolors is arbitrary. Depending on how fancy you want to do this, you might want to do something more complicated. For example, you have 2 course with 10 lines of each and 5-course dinner with 1 row of each. The query above will have to assign the same color to 2 courses of differenct, and it can assign the color "blue" for 2 courses with 10 rows of each. The query above can be modified, if necessary, assign the colors in order of frequency, in order to ensure that two 10-line courses get different colors, and that the colors tend to be more evenly distributed. I'll leave that as an exercise. (Tip: use the frequency in the clause ORDER BY of DENSE_RANK.) To obtain the frequency, use the COUNT function analytical in a subquery. Why do you need a subquery? Discuss among you).

• How to use SQLite temporary tables?

  As read here: http://docs.blackberry.com/en/developers/deliverables/8682/BP_Optimizing_SQLite_database_performance...

  Use temporary tables. Do this only if you do not need data to be available following a reset of the BlackBerry device.

  Read here: http://www.sqlite.org/tempfiles.html

  Tables created using the syntax "CREATE THE TEMP TABLE" is visible only to the connection of database in which the "CREATE TEMP TABLE" statement is initially evaluated.

  The confusing part is that if I create an instance of database for temporary tables with a single statement of DatabaseFactory.open, I am only able to use this same instance of database throughout my entire application?

  So, using the same variable throughout the entire application?

  It also means that I can not close the database connection?

  Here is information on temporary tables of SQLite:

  http://www.SQLite.org/tempfiles.html#tempdb

  (1) you must call 'CREATE TABLE TEMP' every time when you open a database if you need this chart.

  (2) temporary table deleted as soon as you close the database. This means you need to keep the database connection open if you want to run previously inserted/updates of records into a temporary table.

• How to create indexes for the great table of telecom

  Hello

  Please help,

  Hello

  first of all, think of all these SQL for the subquery on MAX (fairy) with analytical functions, the examples given on AskTom of rewriting: http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:9843506698920

  So I'll start with a normal index the MSID (but I think you already have), but provide a compression on the column, I think the same value MSID exist several times in the table. If the performance is not satisfactory or that the plan is not the best, then an option to include more columns can help you.

  I think that the first part of the answer will bring more gain.

  My question is:

  We are running Oracle 9iR2.
  
  And finally, please do not look to find errors in SQL statements above. They are slightly darkened and still developing. The basic question is if TWG's benefit to the common way to do it.
  
  
  Thank you in advance for your help!

  user7066552, the use of temporary tables may be a necessity in SQL Server and mySQL, but with Oracle and its authors do not block readers reading model consistency using temporary tables as part of the treatment is generally unnecessary.

  A valid use for a table of work could be where you create an operating table that is used to generate reports that are run on demand and several different users need access to the same data. However, you create the work only one table and truncate it prior to restocking rather than drop and it dynamically create. When only the current process will use the data a TWG is the way to go if you must have a table that is "temporary".

• How to create a unique temporary table delete automatically after the join?

  I have a lot of users simultaneously accessing web applications.
  My problem is how to fix the SELECT WHERE IN('..') clause ...
  
  I read a lot of threads with the same option...
  
  (1) open the connection and start transaction
  2) create temporary table
  (3) Insert (insert batch) data
  (4) the main objective. SELECT JOIN or SELECT WHERE IN (SUBQUERY).
  (5) end of transaction and close the connection
  
  How can I ensure that the temporary table created was deleting/moving on 5)?
  
  Thank you very much..

  You can do this by using global temporary tables. Also data from the temporary table is automatically deleted after that validation but the table will remain.

  for example

  CREATE TEMPORARY TABLE global today_sales
  ON COMMIT DELETE ROWS
  AS SELECT * FROM Orders WHERE order_date = SYSDATE;

• using temporary Tables

  Hello
  
  I use a temporary table in my procedure to insert and select data. I used ON COMMIT PRESERVE ROWS option.but given in my temporary table are not deleted, even though I explicitly have a close connection to my ASP.NET page. So from now on I use delete (temporary table) to remove the data and insert the new set of records.
  I would like to know why this phenomenon occurs
  
  Kind regards
  

  Hello

  ODP.NET uses the default connection pool, so the connection is not actually closed when you call close/features in your application. This is a limitation of the layer OIC you cannot restore an existing connetion to the State 'blank '... That is to say, the packaging, temporary tables, etc.

  Unfortunately, this makes temporary tables a bit difficult to work with. You can either
  (1) use a transaction in your code odp.net rather than ON COMMIT PRESERVE ROWS to keep the data available until you're done with it, or
  (2) disable connection pool by setting Pooling = false in your connection string, or
  (3) explicitly clear the table do you.

  See you soon,.

• Inserting into a temporary table

  Hi all

  I use this code to insert into a temporary table

  INSERT INTO VISIT_TEST

  (NO, VISIT_ID)

  VALUES

  (1,: ALL_ADMITTED_PATIENT.) VISIT_ID);  -guess: ALL_ADMITTED_PATIENT. VISIT_ID is another number.

  COMMIT;

  It inserts nothing,

  but when I try to insert all the values of pl/sql with the same way

  INSERT INTO VISIT_TEST (NO., VISIT_ID) VALUES (2, 4);

  It inserts with success.

  the code for creating the table of tempo is

  CREATE A VISIT_TEST GLOBAL TEMPORARY TABLE (NO NUMBER, NUMBER VISIT_ID) COMMIT PRESERVE ROWS

  Why does not insert on it data?

  PS: the whole issue is that I run a report from a form, and the query of the report is based on the temporary table.

  what I want to know is, when I run the report from inside my form, is considered a new session, and this is why the report cannot see the data in the table of tempo or am I wrong?

  Thank you

  > when I run the report of my form, which constitutes a new session, and this is why the report cannot see the data in the table of tempo, or am I wrong?

  You're not bad. Forms and reports use separate database sessions. Reports can not see TWG data entered via Forms module.

• Clarification of temporary Table

  I have a small question, I think that must be answered easily, but I couldn't find anything it clarify for me online.

  I have a statement:

  CREATE GLOBAL TEMPORARY TABLE MATR_RPT
  ()PERCENTAGE varchar2()40),
  NUMBER of NUM_OF_CONTRACTS,
  NUMBER OF NUM_OF_CONTRACTS_C
  )
  on commit preserve rows

  BUT if I used "on commit preserve rows" who wouldn t be the same using a standard non-temporary table if it maintains the lines? Or I have forgotten here?

  Thank you!

  on validation keeps the lines:

  On the temporary table will remain once the transaction is complete. These recordings will live as long as the session that inserted is connected to them. After that this session left (dc), records have disappeared.

  on commit delete rows:

  On the temporary table will be gone when the transaction is closed without worrying if the session remains online or disconnect after.

• Temporary tables

  Hi guys,.
  
  Please can you advise if we can create indexes and constraints into Temp Tables can also we grant or revoke access to them or can someone with passwords schema access this particular diagram TEMP tables.
  
  See you soon,.
  Shaz

  The fact is more often that not the use of temporary tables in Oracle is false because all of the databases are not the same, and operations that have been a trend toward the use of temporary tables in SQL Server and Sybase normally does not require the same approach in Oracle where SQL big is often the preferred approach.

  They do not create of redo

  Not quite true that the use of temporary tables generates the cancellation. Undo generates redo.

  Please can you advise if we can create indexes and constraints into Temp Tables can also us grant or revoke access to them or what anyone with the schema > passwords can access the TEMP of this particular schema tables.

  The question is far from clear.

  The content of a temporary table is private.
  Multiple sessions can use a temporary table at the same time, any use of a temporary table is private to the session.
  You can create an index and constraints.
  Privileges of a temporary table are controlled according to any other object.
