Oracle: Nested joins/sub-requetes: odd column names and an unexplained error

The following query works fine. It is a series of nested joins to give me a kind of main table:

SELECT *


FROM proj_trainer k 


JOIN


(


  SELECT * 


  FROM proj_breeder i


  JOIN


  (


  SELECT *


  FROM proj_jockey g


  JOIN


  (


  SELECT *


  FROM proj_horses e 


  JOIN


  (


  SELECT *


  FROM proj_results c


  JOIN


  (


  SELECT * 


  FROM proj_race_details a


  JOIN proj_meet b


  ON a.meet_id = b.meet_id


  ) d


  ON c.race_id = d.race_id


  ) f 


  ON e.horse_id = f.horse_id


  ) h 


  ON g.jockey_id = h.jockey_id


  )j 


  ON i.breeder_id = j.breeder_id


) l 


ON k.trainer_id = l.trainer_id;

It works very well with a strange feature, that is not my main problem. Some columns are back with weird codes such as "QCSJ_C000000001300001". Don't know why, or if it comes to my real problem.

The real problem is that when I add just a subquery join more I get:

ORA-00904: "N"."RACE_ID": invalid identifier

Here is the same code with the additional nested block (the one on the very outside)

SELECT *


FROM proj_entry m


JOIN


(


  SELECT *


  FROM proj_trainer k 


  JOIN


  (


  SELECT * 


  FROM proj_breeder i


  JOIN


  (


  SELECT *


  FROM proj_jockey g


  JOIN


  (


  SELECT *


  FROM proj_horses e 


  JOIN


  (


  SELECT *


  FROM proj_results c


  JOIN


  (


  SELECT * 


  FROM proj_race_details a


  JOIN proj_meet b


  ON a.meet_id = b.meet_id


  ) d


  ON c.race_id = d.race_id


  ) f 


  ON e.horse_id = f.horse_id


  ) h 


  ON g.jockey_id = h.jockey_id


  )j 


  ON i.breeder_id = j.breeder_id


  ) l 


  ON k.trainer_id = l.trainer_id


) n


ON n.race_id = m.race_id AND n.horse_id = m.horse_id;

I felt as if I was on the hill with it and then the last line was wrong somehow, despite having virtually the same structure as all previous blocks. I also used the race_id and the horse_id above in the code so that they work.

I also tried this on the last line:

ON n.race_id = m.race_id AND n.horse_id = m.horse_id;

and a few other variations, with supports etc...

Hello

I can't reproduce the problem, so I can't say with certainty. It might have to do with the same column names which occur in several tables.

Why do you need nested views online?  Why not simply join all tables directly, like this?

SELECT *- or display the columns that you really need

OF proj_race_details one

JOIN proj_meet b ON b.meet_id = a.meet_id

JOIN proj_resuls c ON c.race_id = b.race_id - or a.race_id

...

JOIN proj_trainer k WE k.trainer_id = i.trainer_id - or else

JOIN proj_entry m ON m.race_id = k.race_id - or else

AND m.horse_id = k.horse_id - or else

;

I guess just the tables that contain columns; for example, I can't tell what you posted if proj_race_details or proj_meet contains race_id.  If I guessed wrong, use the correct table alias.  Are eligible all the column names with the correct alias.

  • Using PL/SQL to retrieve column names and column values

    If I have a table as follows

    Table has)

    VARCHAR2 (32)) desert.

    and the table contains a row

    drinks food desert
    -------------------------------------------------------
    Pork chops crispy Apple of iced tea


    Is it possible in pl/sql to retrieve the names of columns and values. I have an object type
    (OBJECT) ACE DATA_DEFINITION_T
    VARCHAR2 (32) 'FIELD_NAME ',.
    'FIELD_VALUE' VARCHAR2 (32)

    I need to store the column name in field_name and the value of column in field_value.

    So, the result would be:

    Field_name = meals
    Field_value = pork_chops

    Field_name = drink
    Field_value = iced tea

    Field_name = desert
    Field_value = croustade

    Thanks in advance.

    The Subscriber to the queue will pick up the message and how to process the data (field_value) based on the field_name (s). With the domain name, it cannot be what to do with the data.

    Sounds like an XML approach would be better than this owner = value field.

    Sort of Yes and no.

    If colname is 'film' and the search string 'star wars' is the place where actually takes the clause...

    WHERE username as username
    AND the movie like 'star wars % % '.

    If username is not limited in any way and it limits just on film.

    Conversely if the column name is "username" and the search string is 'Bob Smith' then where clause evaluates actually to...

    WHERE username like ' %% of Bob Smith.

    then move is not limited in any way and simply limits on the user name.

    Hi all

    I get a 404 error when I select a column name and click the link for dictionary of metadata. I get the 404 because obiee is allowing more 179 characters for the web link. You do not get a 404 error if you click on one of the shorter column names.

    1. What is the user account in the Task Scheduler are you for the work you are trying to use the Task Scheduler?

    The error code indicates that the user account that was used to create the job no longer exists. This could be because the user account is deleted. I suggest that you remove and re-create a job and check if you have the same problem.

    Concerning

    Mr President.

    I recreate my diagram by connecting as sysdba and opens the my database

    then I do not get this message.

    I think that was the problem with my database it has been locked or is created in use of the system.

  • Necessary emergency with a request: fill date of prior art on the column name

    Hello

    Can you please help me with the query. I would be grateful for your time and your help.

    I have the query and the following output. Basically, the query selects a date, a table and counties received documents based on the current date, day-1, - 2 days-, 3 days-4 days-5 days and especially 5 days. It's the query I wrote. Now the requirement has slightly changed and described below.

    Current query:

    Now the desired output:

    The column name must be the date, for example the column name, we're Sysdate, two column name is Sysdate-1 day and the result would look like:

    Hi, just try below as you say it's urgent

    Select sysdate, sysdate-1, sysdate-2, sysdate-3,-4, etc of daul sysdate

    Union

    your query

    (you must ensure for the same type of data)

    are you using oracle report or just in the sql query. If the reports, then you can manage very easily with the introduction of a formula column.

  • There is no possibility of ambiguity in the SELECT clause because any identifier in the SELECT clause must be a database column name

    Hello

    Doc Oracle says the following on the identifiers in the SELECT in PL/SQL clause: there is no possibility of ambiguity in the SELECT clause because any identifier in the SELECT clause must be a database column name.

    If we assume that only valid column identifier are allowed in the SELECT clause.

    But I tried the following:

    DECLARE
toto NUMBER := 10;
tata NUMBER := 0;
BEGIN
SELECT toto INTO tata FROM employees WHERE employee_id = 101;
DBMS_OUTPUT.PUT_LINE(tata);
END;
/

    And there is no error telling me that toto is not a column in the employees table and the result is the same as: toto: = aunt;

    Won't the doc or did I just miss something?

    Thanks for your response!

    Post a link to this Oracle doc.

    But I tried the following:

    1. DECLARE
    2. Toto NUMBER: = 10;
    3. Auntie NUMBER: = 0;
    4. BEGIN
    5. SELECT toto IN Auntie FROM Employees WHERE employee_id = 101;
    6. DBMS_OUTPUT. Put_line (Auntie);
    7. END;
    8. /

    And there is no error telling me that toto is not a column in the employees table and the result is the same as: toto: = aunt;

    ...

    You're right that toto is an identifier, but this isn't a column name.  (Of a subquery) column alias are not database of the names of columns either, nor are the names of the user-defined function.

    Also, there is a possibility for ambiguity even if all the names are the database column names.

    Won't the doc or did I just miss something?

    I can't say until I see the doc you're talking about.

    Oracle documentation is sometimes misleading and sometimes just plain wrong.  For each mistake outright example that I saw in the docs of Oracle, there might be 20 cases where the meaning is unclear or misleading and maybe 200 where I just read it wrong.

  • Display the column name of the column more recently updated

    I wonder if it is possible to display the name of the column in the column most recently updated in a table.

    Example:

    Emp table

    Name

    Height

    Weight

    Age

    Update_Date

    Update_Column

    Original record (03/20/14)

    Name size weight Age Update_date Update_Column

    John                                                 03/20/14          Name

    Then someone comes and update the height on 22/03/14:

    Name size weight Age Update_date Update_Column

    John 5'9 03/22/14 height

    And the Update_date and the Update_column would change again if someone came and put a value for the age. And so on.

    Is this possible?

    Also, if the above is possible, would it be possible to display the name of extreme right column if a user updated several columns at the same time?

    Example:

    User updates the sub-folder:

    Name size weight Age Update_date Update_Column

    John 5'9 03/22/14 height

    And adds weight and age at the same time on 24-03-14:

    Name size weight Age Update_date Update_Column

    John 5'9 150 31 03/24 / 14

    The Update_Column would display age because it is the furthest to the right. (Think by reading from left to right, the column that has been updated if the extreme right)

    So to sum things, I need to be able to display Updated_date (which will be the date of the day when the record is the last updated) and Updated_Col (which is the column name of the column was last updated, and if multiple columns are updated then display that value has been updated last in)

    I hope that the examples help to clarify things.

    Thank you

    Steven

    I think I found a solution.

    delimiter //
    create table a (
      id int (10) unsigned auto_increment,
      a int(10),
      b int(10),
      update_date datetime NULL,
      update_column varchar(16) NULL,
      primary key (id)
    )//

    create trigger bu_a before update on a for each row begin
      set NEW.update_date = NOW();
      set NEW.update_column = NULL;
      -- you need to start with the rightmost column if you want
      -- that matched with the highest priority
      if OLD.b != NEW.b then
       set NEW.update_column = "b";
      elseif OLD.a != NEW.a then
       set NEW.update_column = "a";
      end if;
    end //

    TEST

    insert into a (id,a,b) values (1,1,1), (2,1,1), (3,1,1), (4,1,1)[

    update a set a = 2 where id = 3;
    update a set a = 2 where id = 4;
    update a set b = 2 where id = 4;
    select * from a;
