one-to-many relationship

• One-to-many relationship repository

  Hello.

  When a repository item have a data type = "list" and a type of COMPONENT-component-, is there a way to remove the items referenced all when calling the Set accessor for the list?

  Because we have to replace the entire list and we do not want to keep the old data.

  I see two ways to possibly go about,

  First of all, as you substitute completely the list of itemdescriptor property, so when you set the listproperty for itemdescriptor in your code, first delete this list (which would be a component item type) put cascade = remove its property that is referenced in xml format, and then create the list with the values you want and that you assign this list to your itemdescriptor listproperty

  http://docs.Oracle.com/CD/E41069_01/platform.11-0/ATGRepositoryGuide/HTML/s0610cascadedelete01.html

  Another approach I can think in case you do not want delete listtype property is that you can use the type of consumer or the custom property for list of property and override the method for this property setPropertyValue.

  http://docs.Oracle.com/CD/E41069_01/platform.11-0/ATGRepositoryGuide/HTML/s0715userdefinedpropertytypes01.html

  in thing first method setPropertyvalue you can do is get all referenced items associated with this particular list item from the repository id, it is possible via Reposiory query, and then delete the referenced articles and then call the super.setPropertyValue method to set the new values in this listproperty.

• Two tables that have a relationship as "many-to-many" and "one-to-many.

  I have the next two represents tables users and the other represents the items where each item can have an author (user) and of course, users can create a lot of articles, so the one-to-many relationship: -.
  
  1. users: -.
  User_id (primary_key)
  User_name
  User_sex
  user_address
  
  2.ARTICILES: -.
  Article_id
  Text
  Author_id (foreign key to the users.user_id)
  
  but the problem I have been facing is that, on another requirement each items can have several (users) approval before being published, so in this way have become the many-to-many relationship, so I created a third table called "trusts": -.
  
  3.approval: -.
  approval_id (foreign key to the users.user_id)
  article_id (foreign key to the articles.article_id)
  level.
  
  so is this a good approach to flow, or there is another way I can better build these tables.

  Hello
  Relationship seems to be ok for your current condition. but make sure you have sequence approval on your table to the approval, in case you should find the flow of approvals.

• One to many with several tables on one side and a table on the side "several."

  Sorry for the confusion in the title. Here's my question. In my program, I have 2 different tables that store the 2 different types of entities. Each entity has a list of attachments that I stored in a table of common attachments. There is a one-to-many relationship between the entity and the attachments table tables.
  
  () ENTITY_ONE
  ID
  NAME
  )
  
  () ENTITY_TWO
  ID
  NAME
  )
  
  ATTACHMENTS)
  ID
  ENTITY_ID
  ATTACHMENT_NAME
  )
  
  ENTITY_ID of attachments table is used to link the attachments to the one entity or two entity. All codes are generated by a single sequence. Thus, they are always unique. My question is how can I map this relationship in the EntityOne, EntityTwo and attachment JAVA class?

  For EntityOne and EntityTwo, you can simply define a normal OneToMany mapping using the foreign key.
  You use the TopLink API or APP? JPA requires a mappedBy to the OneToMany, so this may be more difficult. You should be able to simply add a JoinColumn on the OneToMany and make the Insertable/editable = false column.

  To fix, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain in force in your model or use a VariableOneToOne to TopLink mapping (this will require a common interface on behalf of entities).

• many-to-many relationship, recording is not linktable

  Got a little a legacy application that previously had flushAtRequestEnd set to true.  We have knocked down the flag, and now our many-to-many relationships do not work properly.  Save individual records very well, BUT the link table records are not created.  Here's how the entities are essentially in place.

  persistent component = "true" table = {'encounters'

  ...

  property

  name = "CaseFollowUps".

  SingularName = "CaseFollowUp".

  FieldType = "many-to-many.

  CFC = "FollowUp_NEW."

  LinkTable = "EncounterFollowUp."

  fkcolumn = "EncounterID."

  inversejoincolumn = "FollowUpID;

  ....

  public function addCaseFollowUp (fu) {} void

  ArrayAppend (variables. CaseFollowUps, fu);

  arguments.fu.addEncounter (this);

  }

  ...

  }

  persistent component = "true" table = {'FollowUp_NEW'

  property

  name = 'encounters '.

  SingularName = "meeting".

  FieldType = "many-to-many.

  CFC = "meeting".

  LinkTable = "EncounterFollowUp."

  fkcolumn = "FollowUpID.

  inversejoincolumn = "EncountersID";

  }

  I call the practical method of "addCaseFollowUp" a pre-existing meeting within a transaction.  No error thrown.  I see this code of Hibernate for the insertion of the FollowUp_NEW registration:

  Insert

  in

  FollowUp_NEW

  (Note, UserDateTime, UpdateDateTime, CreateDateTime, DispositionID, FollowUpRequestID, CommunicationTypeID, username)

  values

  (?, ?, ?, ?, ?, ?, ?, ?)

  But I don't see a request to Hibernate for the insertion of the EncounterFollowUp record.

  
  

  Suggestions?

  Is it perhaps a query that updates EncounterFollowUp? If there is nothing, then run the code as one only. This woud the fact rule the ORM session ended prematurely.

• 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.

• 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.

• How to create the Group of cache for many to many relationship tables?

  Hi, Chris,.
  Page 4-4 < < the user manual of the Oracle Database Cache in memory > > there is a saying,
  A child table cannot reference multiple parent tables.
  If there is a many-to-many relationship table in Oracle and I want to cache in TT, there is not a la carte approach that?
  Or I have to logically break his references to the two tables in one of them?
  I forgot to mention that I have a root table and one of its child tables is a many-to-many relationship table.

  Yes, that's correct. You can not exactly this model in TimesTen. You to omit some of the relationships so that things are defined in TimesTen as a pure parent/child relationship. You can also consider putting the tables into groups separate cache. Of course, there are consequences to this:

  1. the 'missing' relationship cannot be run by TimesTen. The application must respect/run it. If this is not some updates may not to be propagated to Oracle if they violate the relationship in Oracle.

  2 If the parallel AWT is configured (to improve the performance of spread) it will not be used for all tables where they lack of relationships. All updates to the tables in the order will apply.

• 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.

• Creating a unique index frame on a one-to-many table and search

  Hello
  
  I was properly put in place of the full text index on multiple columns on the same table (using the MULTI_COLUMN_DATASTORE preferences), but now I have a situation with a table of one-to-many data collection (with a CF of a lookup table), and I need to get columns through two of these tables. Code example below, several of my chatter after the code block:

  I want to be able to create a text index to group these fields:
  
  SUBMISSION_ADVISORS. FIRST NAME
  SUBMISSION_ADVISORS. LAST_NAME
  SUBMISSION_ADVISORS. SUFFIX
  ADVISOR_TYPE. ADVISOR_TYPE_NAME
  
  I looked at DETAIL_DATASTORE and USER_DATASTORE, but examples of Oracle Docs for DETAIL_DATASTORE leave me a little confused. It seems that this should be fairly simple.
  
  Ideally, I try to avoid creating new columns and keeping a minimum shutter adjustments. But I'm open to any suggestion. Thanks for your time and your thoughts.

  I would create a procedure that creates a virtual with labels document, what is the multi_column_datatstore behind the scenes. Then I would like to use this procedure in a user_datastore, so the result is the same for several tables as a multi_column_datastore for a table. I would use auto_section_group or another type of Group of sections, so that you can search from WITHIN as with the multi_column_datastore. Please see the demo below.

• 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.

• With a many to many relationship data in a table - recursive sql?

  Hello
  I'm trying to group data associated with a many to many relationships in a number of unique group using SQL only. The table looks like this.
  
  AMOUNT OF THE CHECK PLAN
  
  1 10
  A 15 2
  2 11 B
  3 12 B
  4 13 B
  4 16 C
  5 17 D
  
  The result should look like this. Since A is linked to 2, 1 and 2 correspond to the B and B are related to 3 and 4, 4 is related to C, these lines should be considered as a group. Any direction on where I should start looking for or if there is no function of Oracle that will be much appreciated. The version of oracle's 10g.

  Hello

  Good thing you're uisng Oracle 10. I don't think you could do this in pure SQL using any earlier version, but the CONNECT BY NOCYCLE feature, introduced in Oracle 10, makes this possible.

  WITH     got_groupname     AS
  (
       SELECT     checkid, plan, amount
       ,     MIN (CONNECT_BY_ROOT checkid)     AS groupname
       FROM     grpdel
       CONNECT BY NOCYCLE     (     checkid     =  PRIOR checkid
                         AND     plan     != PRIOR plan
                      )
                 OR     (     checkid != PRIOR checkid
                      AND     plan     =  PRIOR plan
                      )
       GROUP BY  checkid, plan, amount
  )
  SELECT       g.*
  ,       DENSE_RANK () OVER (ORDER BY groupname)     groupid
  FROM       got_groupname      g
  ORDER BY  checkid
  ,            plan
  ;
  

  Output:

  CHECK PLAN AMOUNT GROUPNAME GROUPID
  ----- ---- ------ --------- -------
  A        1     10 A               1
  A        2     15 A               1
  B        2     11 A               1
  B        3     12 A               1
  B        4     13 A               1
  C        4     16 A               1
  D        5     17 D               2
  

  You did not ask the groupname column, but I realized just to help show how it works. The subquery got_groupname associates each checkid with each other the checkid, regardless how many not deleted the two lines are. MIN finds the lowest checkid that each is bound, which generates a unique group identifier. Personally, I sould like usage of groupname as identifier. It tells you in the blink of an eye that B is a member of the same group has. However, it is not the same as that of a certain number, so if you need a number, you can derive from groupname with the analytical DENSE_RANK function.
  In many versions of Oracle, CONNECT BY queries do not work properly if they contain functions analyric. I don't know if this is the case in your version, but I don't think it's worth taking a chance. By CONNECT BY in a subquery no analytical function and then by the analytical function in a super-requete, we eliminate any chance of such a conflict.

  Thanks for posting the CREATE TABLE and INSERT statements; It is very useful.
  You want to be more useful? Do not publish the name of schema, PAS_DBA. Not many people who want to help you have a schema called PAS_DBA, and they probably won't create a. He probably doesn't. ' t help, either; probably, you connect PAS_DBA to create the table in any case.

• 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.

  This can help you

• AWM - many-to-many relationship into a hierarchy of levels

  Hi, I use awm 11.2 and the problem is, how to create the relationship in this case:
  
  I have a customer dimension with a hierarchy that has the following levels:
  
  1. women
  2 date_of_birth
  3 countries
  4 city
  5 adresse_rue
  6 first_last_name
  
  
  Problem is the relationship between sex and date of birth, because they have the same number of dates of birth sex and vice versa.
  
  Is it possible to do in MN and how?
  
  Thank you

  Basically, you're right, but it still isn't a solution, if we have a case as I wrote.

  You can make your design work if you make each Member map to exactly one parent. Dates of birth must roll for exactly one sex. In other words, for the date of birth 01/01/1980 you will need a male and female version: M_1/1/1980 and F_1/1/1980. Everyone can have a description of 01/01/1980 or "1 January 1980" or whatever you want, so that they can be combined. But the value of full member must be different.

  So, technically, you have a solution to force it to work, but I still don't see how this particular dimension made a lot of sense as expected.

• Only one link, many cases?

  I'm new to InDesign but experienced with Illustrator. I use CS5.5.

  I've got work in Illustrator for a set of 6 icons. I want to import files 6 icon (Illustrator format) in InDesign, and then copy and paste icons several times into the cells of a table I created. My first attempt at this led links of 292 display panel (divided between the 6 icons). I don't think I'm doing this right. Should the links Panel show just 6 links (one for each imported Illustrator artwork file) and I copy and paste an "instance" of this link? This would be akin to Illustrator where you can convert work in a 'symbol' and whenever you copy and paste that you are dealing with a symbol 'instance' rather than a duplicate of the real work (reducing the size of the file).

  That's how it should work, but you can see the file several times it's only once in memory of InDesigns.

  Since CS5 however you have been able to change how they are displayed, see the circle arrow in this picture:

  

  You can click on that to narrow the list down to one line, and it will show how many instances of the link there is between parentheses.   If you want to replace the link click on the top line and recreate a link and you are going to do all instances at once, or click an individual instance to replace than this one.
