• BAD RESULTS WITH OUTER JOINS AND TABLES WITH A CHECK CONSTRAINT

  HII All,
  Could any such a me when we encounter this bug? Please help me with a simple example so that I can search for them in my PB.

  Bug / / Desc: BAD RESULTS WITH OUTER JOINS AND TABLES WITH a CHECK CONSTRAINT
  
  
  I ran the outer joins with check queries constraint 11G 11.1.0.7.0 and 10 g 2, but the result is the same. Need to know the scenario where I will face this bug of your experts and people who have already experienced this bug.

  Why do you not use the description of the bug test case in Metalink (we obviously can't post it here because it would violate the copyright of Metalink)? Your test case is not a candidate for the elimination of the join, so he did not have the bug.

  Have you really read the description of the bug in Metalink rather than just looking at the title of the bug? The bug itself is quite clear that a query plan that involves the elimination of the join is a necessary condition. The title of bug nothing will never tell the whole story.

  If you try to work through a few tens of thousands of bugs in 11.1.0.7, of which many are not published, trying to determine whether your application would be affected by the bug? Wouldn't be order of magnitude easier to upgrade the application to 11.1.0.7 in a test environment and test the application to see what, if anything, breaks? Understand that the vast majority of the problems that people experience during an upgrade are not the result of bugs - they are the result of changes in behaviour documented as changes in query plans. And among those who encounter bugs, a relatively large fraction of the new variety. Even if you have completed the Herculean task of verifying each bug on your code base, which would not significantly easier upgrade. In addition, at the time wherever you actually performed this analysis, Oracle reportedly released 3 or 4 new versions.

  And at this stage would be unwise to consider an upgrade to 11.2?

• Indicator of waveform data dashboard with multiple locations

  I have a chart in waveform with multiple locations on my main VI running.

  I use the Application Dashboard data 2.2.1 on my Ipad to monitor table of wave shape of my running app.  I placed a marker on my Ipad and also related waveform with my waveform array variable.  I can't play my data dashboard application because it shows unable to connect to the server.  I noticed that it is because of multiple plots being plotted on my table of waveform.

  I could only play the App data dashboard when it is just a single parcel related to an indicator on the App.

  My question is if it's possible to have a graphical indicator of waveform on a data dashboard that has several plots being plotted and not only a single square, and how to configure it?

  Thank you.

• Select Date Max with more than one result

  Hello;
  
  I need to write a query that returns the maximum date for a specific transaction that is not a problem, but my problem occurs when I have several transactions with the same date max trans.
  
  
  Can someone help me write something which will return only one record from a result set that has more than one record
  
  Example:
  
  TRAN_ID - LAW #-TRANS_DATE
  -272-1111111-29/10/1999 00:00:00
  -273-1111111-29/10/1999 00:00:00
  -274-1111111-29/10/1999 00:00:00
  -275-1111111-29/10/1999 00:00:00

  You are referring to your alias at the wrong level, try this:

  select * from (
  select account_transaction_id,
         account_number,
         max_days_in_arrears,
         trans_date,
         row_number() over(partition by account_number order by trans_date desc, account_transaction_id desc) as rn
    from account_transaction atr
   where max_days_in_arrears > 90
     and account_number in (100026, 121189, 100223)
     and trans_date = (select distinct max(trans_date)
                         from account_transaction
                        where account_number = atr.account_number
                          and max_days_in_arrears > 90)
   order by account_number, trans_date
  )
  where rn = 1;
  

  and use code tags please, so that your queries can still be read easily and quickly for us to understand.

• Max() with outer join

  I have a couple of tables XX_PERS and XX_ADDRESS as shown below. I would like to return more recent 'city' for each person on the xx_pers table. If no record matching in xx_address, there should always be the id of the person, name of city as null.

  CREATE TABLE xx_pers

  (Key primary ID number,)

  name varchar2 (100)

  );

  CREATE TABLE xx_address

  (

  addr_id PRIMARY KEY NUMBER,

  pers_id NUMBER,

  City VARCHAR2 (25).

  FOREIGN KEY (pers_id) REFERENCES xx_pers (id)

  );

  insert into xx_pers values (1, 'Messi');

  insert into xx_pers values (2, 'Muller');

  insert into xx_pers values (3, 'Ronaldo');

  insert into xx_address values (100.1, "Argentina");

  insert into xx_address values (102.1, "Madrid");

  insert into xx_address values (101.2, "Germany");

  insert into xx_address values (103.2, "Munich - OF");

  The following query returns the most recent 'city' for person 1 and 2 but do not know how to get the 3rd person.

  SELECT ID, name, city

  of xx_pers xx

  , xx_address y

  Where xx.id = y.pers_id

  and y.addr_id in (select max (addr_id) of the xx_address by pers_id group);

  Hello

  Here is another way, which is similar to what you have tried initially, but it uses an outer join to a subquery instead of an IN subquery:

  WITH got_max_addr_id AS

  (

  SELECT pers_id

  MAX (addr_id) AS max_addr_id

  OF xx_address

  GROUP BY pers_id

  )

  SELECT p.id

  p.name

  a.city

  OF xx_pers p

  LEFT OUTER JOIN got_max_addr_id ON m.pers_id = p.id m

  A LEFT OUTER JOIN xx_address ON a.pers_id = m.pers_id

  AND a.addr_id = m.max_addr_id

  ORDER BY p.id

  ;

  It is also very similar to the solution in response #2 above.

  Note Although all 4 of these solutions something in common that is different from the query you posted: they use all of the outer joins.  You obviousy has estimated that an outer join outer join would be useful here, because you mentioned an outer join in the title of the thread, but you are not one yourself.

• How to create the data store with multiple LUNS

  I have a collection of ArrayCollection of time intervals that I want to use as the source for a series of ComboBoxes in several separate components.

  What is the best way to implement this?

  In fact, you can have global data objects. Since Flex is manufactured with components, it's kind of deprecated. But if create you a collection of public register in your home page, you can access it via the name of Application.application.var. When you type Application.application.

  Union of all the

  But I have not the same column that all the table, some are missing. When I write one - PL/SQL query I can easily add a false "NULL column1' column, but I can not how I do with ODI 11 g.

  I tried not to use "Active Mapping", but it does not work.

  I'm newbie ODI 11 g

  Hi, Myra,.

  I'd even as in PL/SQL. In your table target add all the columns you need and overall data whatever you're missing some columns just put NULL in the mapping.

• Gears - error when you try to insert values into a table with multiple columns

  Hello

  I started playing with the gears and SQlLite today and I get an error when I try to insert values into a table with multiple columns.

  I have:

  var db = google.gears.factory.create('beta.database');
      db.open('developerSet');
      db.execute('create table if not exists Developers (DeveloperName text, DeveloperAge int)');

          alert('success');

  I get the error:

  Yes, a SQLite database will persist between battery pulls.  The database is registered either to internal MEM or removable media (not the device memory), depending on which is available on your device.

  In general, its not considered a best practice to remove your table as soon as it is empty and re - create it again when you want to add data.  This adds extra overhead fresh for the final, delete and insert first for a given table.  Instead, define and finalize your drawing before you create your table.  Once created, review the static schema.

  That being said, for development purposes, it may be easier to provide an easy way to drop your tables while you develop your schema.

  See you soon,.

• How to export data to excel that has 2 tables with the same number of columns and the column names?

  Hi everyone, yet once landed upward with a problem.

  After trying many things to myself, finally decided to post here...

  I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.

  It works very well with a single table. The problem now is that I cannot do the same with 2 tables.

  Because the tables have the same number of columns and the columns names.

  Here are the 2 tables with column names:

  Table-1 (MONTHLY_PART_1)	Table-2 (MONTHLY_PART_2)
  SL_NO	SL_NO
  MODEL	MODEL
  END_DATE	END_DATE
  U-1	U-1
  U-2	U-2
  U-4	U-4
  ..........	........
  ..........	........
  U-20	U-20
  U-25	U-25

  Given that the tables have the same column names, I get the following error :

  402 error at line 103, column 4

  required aliases in the SELECT list of the slider to avoid duplicate column names.

  So how to export data to excel that has 2 tables with the same number of columns and the column names?

  Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?

  Help me with this please.

  Thank you.

  Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?

  see you soon

  About 100 the number of columns, please someone suggest how to use the update with a join of two tables.

  Hello

  If all the values needed to update a given line from table_x come from the same line of table_y (or in the same row of a result set of a query on a number any of tables), then you can do something like this:

  UPDATE  table_x  x
  SET     (col1, col2, col3, ...)
  =     (
           SELECT  NVL (y.col1, x.col1)
           ,         NVL (y.col2, x.col2)
           ,         NVL (y.col3, x.col3)
           FROM    table_y  y
           WHERE   x.pkey   = y.expr
           AND         ...
       )
  WHERE   ...
  ;
  

  If the WHERE clause is based on the same line of table_y, then it will be probably easier and more efficient to use the MERGER instead of UPDATE.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
  In the case of a DML (UPDATE), for example, the sample data should show what looks like the tables before the DML, and the results will be the content of the or the tables changed after the DML.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Combine data sources with different granularity in the same fact table?

  I have two operating tables 'Incident (157 columns)' and 'unit (70 Colums) '. For all the "incidents" happening there could be one or more records in the table of the 'unit '.
  
  As part of my design of data mart, I have merged the tables in one "makes the incident (227 columns)" and insert records from two tables with a join condition between them [incident. IN_NUM = Unit.IN_NUM].
  
  Is this correct, is my question? or am I mix data sources with different granularity in the same fact table. Appreciate your help.
  
  Best regards
  Bees

  Bees,
  Are the measures of the 'Incident', repeated during an incident given, in more than one record in the table of the unit? If so, then the sum (indicent.measure) will give an incorrect result?

  What is there to merge physically tables set outside OBIEE? With OBIEE you might have a table of 'facts' logic to present the user with report, which from tables separated units and Incidents and would stop the occurrence of incorrect aggregations. A common piece of modeling in the same way would be arrested in OBIEE headers and lines of command, quite common to have a logical fact 'orders' which contained the two header orders and order line, this translates into the Incidents-> relationship of units.

  To do what I mentioned, is relatively simple, you need a "Dim - Incident" at two levels, unit, mapp and Incident unique identifiers as keys to level and then use these levels to define the content of the levels correctly in your 2 tables logic sources logic "done", IE the LTS Incidents at incident level LTS units as level of units.

  Hope this helps, let us know if you get stuck.
  See you soon
