• Kindly help me with the request to find the data in two tables

  Hello Guru
  
  Kindly help me to recover the data from two tables-
  
  BASEBALL
  LEGAL_ENT_ID (PK)
  GAME_ID (FK)
  LEGAL_ENT_NM
  INACTIVE_DT
  DATE OF INS_TS

  and if I want fecth data from these two tables according to the following condition then it is fine with the suite of applications.
  
  1 select distinct values only table of BASEBALL by using the following query.
  
  SELECT DISTINCT B.GAME_ID as 'CLEARING GAME ID', B.BRKR_NM "NAME of THE GAME of COMPENSATION" OF BASEBALL A, FOOTBALL B WHERE A.BROKER_RELATION_CD IN ('FUTBRKR1', 'FUTBRKR2') AND A.GAME_ID = B.GAME_ID
  
  2 Select all the table BRKR_NM OF FOOTBALL as well by using the query - next
  
  SELECT GAME_ID "RUNNING GAME ID", 'NAME OF THE GAME OF EXECUTION' BRKR_NM SOCCER
  
  Now, my query is that--
  
  I want a query that gives me a combination of above mentioned queries... and if I tried to use Union or Union All, then she is not giving me the result as expected.
  
  I like the result to look like who has a few conditions such as -
  1 - the records in the table Football are high vs Baseball table because there is no condition to filter the records of the Football.
  2 - football is a superset of records and Baseball is a subset.
  3 - COMPENSATION NOM_JEU and RUNNING NOM_JEU may return the same values as well.
  
  I want the result to be in the following form-
  
  EXECUTION ID GAME | NAME OF THE GAME TO RUN. COMPENSATION ID GAME | DELETE THE NAME OF THE GAME.

  Of course, you'll want to change the types of data, etc. as needed.

  I assumed that the XML can contain several "" sections and that each section can contain several entries.

  Thus the XMLTABLE aliasing as 'x' gives information of XML, and supplies the data associated with the XMLTABLE with alias 'y' which gets the multiple authors, which itself section of the XMLTABLE with alias 'z' for each of the article_item.

• Button insert data to the table

  Hello

  I use APEX 4.2.3 with XE, I try to insert data into the table using code below but nothing happen when I press the button, create this button like 'create a button to point to page'-> 'dynamic action'-> 'run pl/sql '.

  begin
  insert into dummy values('xx');
  commit;
  end;
  
  

  So to clarify, you have

  (1) created a button that "action" is "defined by the dynamic action.

  (2) created a dynamic action that executes pl/sql at the click on the button and you are pl/sql?

• Cascading list of values with a many-to-many relationship

  Hi all

  I have three paintings; semester, subject and half of subject. Each semester has a lot of topics and a subject can be taught in several semesters.

  create table semester(
       id number not null,
       name varchar2(50) not null,
       primary key(id)
  );
  create table subject(
       id number not null,
       name varchar2(50) not not null,
       primary key(id)
  );
  create table semester_subject(
       id number not null,
       semester_id number not null,
       subject_id number not null,
       primary key(id),
       foreign key(semester_id) references semester(id),
       foreign key(subject_id) references subject(id),
       constraint semester_subject_uq unique(semester_id, subject_id)
  );
  
  

  EDIT: I have a page with a report that shows all students who are currently enrolled in the selected for the selected session object.

  There are two selection lists at the top of the report, one for the half and the other for the subject.

  What I try to do is when you select a semester in the half selection list, the topic selection list should contain only the subjects for the half of some (not all) in the subject of the painting.

  h

  If the relationship was of 1 to many that I could write to see half of value

  select name, id
  from semester
  order by 1
  
  

  and for the purpose of value list

  select name, id
  from subject
  where semester_id = :PX_SEMESTER
  
  

  But now that the relationship depends on the table of semester_subject, I can't find a way to achieve this and Googling has not helped.

  Thanks in advance for any help.

  I believe that this issue has also been implemented on stack overflow plsql - list of values cascading with many-to-many relationship - stack overflow and received a very wide response. If the OP has not yet verified, he may want to.

• Is an extra Associative entity automatically created when we do a lot of many relationships?

  Hello

  I use SQL DEVELOPER DATA MODELER Version 4.0.2.840.

  My question is when we create many to-many between two main entities let PRODUCT and SALES (master). then we want to create a table associative entity SALES_DETAIL (details of sales)

  Is there an option that allows me to create an associative entity automatically with two associations of old masters. As it is automatically created with TOAD DATAMODELER.

  Thank you.

  Hello

  many-to-many relationship is transformed into associative array / intersection during the engineering to the relational model. If you add attributes to the relationship that they will turn to the columns of this table. Use "Show > attributes of the relationship" in the context menu of the diagram so that they are visible on the diagram.

• How to implement many of many relationships?

  I've been google searching for articles on the implementation of many-to-many relationships and find as many hits I'm swamped.
  Someone at - he preferred an article on this topic?
  
  In my example, I have a number to-many between the table 'user' and 'project' of the table.
  Why do some articles indicate that the primary key of the table of links 'UserProject' contains two foreign keys for 'user' and 'project '? If we want to find all projects for a given "user.id", we not specifying the "project.id". It will not be reduced in a linear search then?
  
  I thought we should receive the 'fk_user' foreign key as the primary key and create an index of the "fk_project" (or vice versa). So if we specify the "user.id" we can quickly find all the corresponding values of 'project.id '.
  
  There are oracle-specific issues I should know about?
  
  Thank you
  Siegfried

  As you guessed, a primary key is intended to preserve the unique character.
  If you have a composite primary key, so if you provide columns in the predicate (where clause) that are the primary key columns, then they can help you with an effective search.

  If you have a requirement that you have aquery that always uses the 2nd and 3rd in the columns of the primary key, but never the first column, then you might want to add a composite index on these two columns.

  Remove the referential integrity of a production database is pretty much one of the worst things you can do.
  Think about the consequences: you'll have records of children who do not have a parent record or worse have the incorrect parent record. It is best to not leave a record get in the database to allow incorrect data.

  Incorrect data are a nightmare to fix, as its very difficult to find the source, and worse still, it can remain unnoticed for years.

  Your mantra should be to avoid bad data in the database. This by applying constraints at the level of the database.
  This means that all data entered with conform to these rules.

• one-to-many relationship

  Read the article here...
  
  http://www.databaseprimer.com/relationship_1tox.html
  
  To illustrate the one-to-many relationship consider the table of sampling plan and data below:
  authors table
  ============
  author_id (primary key)
  LastName
  FirstName
  book_id (foreign key - link to table books book_id)
  
  
  table Books

  then how the data on the "authors" table columns 'author_id' and 'book_d '?
  
  don't know how to frame the table 'authors '...
  
  It would become the relation 1-1... is it normal?
  
  Please help how data will be in the "authors" table
  
  Thank you

  You do not want to have a database template that you have illustrated below. Why? Well to start tt does not pass even the first normal form. Secondly, if you had ever updated the author's name, you will need to update in several places, which could lead to problems of data integrity. A database designed to reduce redundancy, the structure that you have proposed increases it.

  If you had been modelling a one-to-many relationship, it would be more appropriate:

  CREATE TABLE authors
  ( author_id  NUMBER        PRIMARY KEY
  , last_name  VARCHAR2(200) NOT NULL
  , first_name VARCHAR2(200) NOT NULL
  );
  
  CREATE TABLE books
  ( book_id NUMBER        PRIMARY KEY
  , title   VARCHAR2(200)
  );
  
  CREATE TABLE authors_of_books
  ( author_id NUMBER NOT NULL REFERENCES authors(author_id)
  , book_id   NUMBER NOT NULL PRIMARY KEY REFERENCES books(book_id)
  );
  

  This models your one-to-many relationship with a "join" table or "bridge." The drawing above gives you the ability to change the author freely or to book the title attributes in the same place increases your data integrity.

  However, a many-to-many relationship may be more appropriate since multiple authors can write a book. So you would change the tables authors_of_books as follows:

  CREATE TABLE authors_of_books
  ( author_id NUMBER NOT NULL REFERENCES authors(author_id)
  , book_id   NUMBER NOT NULL REFERENCES books(book_id)
  , CONSTRAINT authors_of_books_pk PRIMARY KEY (author_id, book_id)
  );
  

  I hope this helps!

• How I find myself with as many vmdk files (which are almost 320KO)?

  I'm new at this; Please, be gentle .

  I made a new Win 7-64 company VM Workstation 8.0.5. I asked a 60 GB of virtual disk in place with several files, and I found myself with 64 vmdk files (49 of which are 320 KB).

  I did the same thing a few months (on an earlier version of workstation) and 60 GB of virtual disk includes only 10 files vmdk, ranging from 1 GB and GB 28.

  Why the new VM do not end with as many files vmdk more and so much smaller?

  Thank you

  David

  David, although this was not really necessary, because I had already explained the plausible scenarios thanks nonetheless for the supply of the parsed data (factual) hard.  The reason why you have 64 files in the same directory hard is because the virtual machine has a 60 GB twoGbMaxExtentSparse virtual disk with a snapshot, and it is 32 hard files (for each) x 2 for a total of 64 records hard.  There is absolutely nothing wrong with this and is a scenario quite normal and expected and because it is so absolutely no sense why whatever mfelker made such a statement absurd as, "it's simply imposible t have 64 hard files in the same directory." and you can certainly security ignore this!

• How to display a many-to-many relationship?

  Hello
  I wonder how would you present the master-detail-data of an n: m-relationship in the ADF?
  
  Suppose we have a table x and a y in the table, the xy table is our cross refrence table.
  
  I know that you could represent the realtionship via associations and display links, it is not clear to me how to display the detail data but I don't want to show the features of the cross-reference-table (xy).
  Instead, the data in the table there should be presented as details of table x.
  
  I hope you understand what I'm shooting.
  
  Thanks in advance.

• How to handle many-to-many relationship

  Hello friends,
  I'm confused, how do many many relationships in my application:
  
  I have agents and projects of two tables.
  Each agent can manage several projects.
  Each project can be handled by several agents.
  
  Example of table INIT_PROJECT:

  ID , PROJECT
  1  , X Tower
  2  , Y Tower
  3  , Z Tower

  Example of table INIT_AGEN:

  ID , Agent
  1  , A
  2  , B
  3  , C

  What is the correct way to join or to represent the relationship between the two tables to get a table that servers as a lookup table also:
  
  is - it to be like this:
  
  Example 1 in new_table
  

  Project_ID , Project_name, handled_by1, handled_by2, handled_by3, handled_by4
  1             , X tower        ,  A              , B

  or is it:

  ID            , Project_name, handled_by
  1             , X tower        ,  A            
  2             , X tower        ,  B              
  3             , X tower        ,  C   
  4             , Y tower        ,  A              
  5             , Y tower        ,  B              
  ........
  .....             
             
    

  Then, on a FORM I have lists of values.
  Projects and Agents.
  When the user selects a project, he or she can only see the agents engaged in this project in the list of Agents of values.
  I use a shuttle box for inserting the values "managed by".
  
  Or do like this:
  Example 2 of new_table

  ID , PROJECT,...,HANDLED_BY
  1  , X Tower,... ,A:B:C:D
  2  , Y Tower,... ,A:F:G:I
  3  , Z Tower,... ,F:A:I:W

  I have two lists of values:
  'Project name' and 'Agent '.
  When the user selects a project, then he must see only the values of the handled_by that are associated with this project only.
  
  I used this query to prepare the values in the list of officers of the value
  

  SELECT  
    distinct REGEXP_SUBSTR(handled_by, '[^:]+', 1, LEVEL)  d , REGEXP_SUBSTR(handled_by, '[^:]+', 1, LEVEL) r
     
    FROM  (
           SELECT   project, ROWNUM AS id
           ,      handled_by
           FROM   projects 
          ) where project = :P8_project
    CONNECT BY INSTR(handled_by, ':', 1, LEVEL-1) > 0
           AND id = PRIOR id
           AND PRIOR DBMS_RANDOM.VALUE IS NOT NULL; 

  Can you please advice what is the right way?
  
  Best regards
  Fateh

  Somone was asked once to use the relation tables in that many many cases and I used it since with no problems until now.

  To apply in your case, I therefore project table, agent and a relationship table call PROJECT_AGENT_R which has

  (1) project
  (2) Agent_ID

  The primary key for each table as a foreign key.

  You can update the relationship via process page in your table when after you have created a project for an agent.

  Do not use string concatenated as your code above as it can be annoying and not really a good practice.
