  • Insert values in multiple tables. One of the tables has complex primary key.

    Hello, I am using Jdeveloper version 11.1.2.3.0
    I have a table FORM_TYPE and another table Str. The Str table is used to translate strings from the table name which are read from another program from the database and used to generate forms..
    The FORM_TYPE  table has a relation to the STR table via formtype.title_str_id = str.str_id.
    The STR table has a primary key that is depending on mf_language and str_id columns. I generated entity for the STR table but can't insert from the application module new values for some reason... It says the record invalidates its own entity..
    I am trying to create a table that will be editable and will have the columns Description, Name, Str in English, Str in French etc...
    Want to create a Form_Type and in the same time to insert new values for each language... But can't make the inserts of the new STR work..
    Also the    FormType.TITLE_STR_ID has many values null already in the database.

    Tried that I made view links and associations but still can't insert in both tables at once... Could be because the tables aren't having relationship between them or because the STR table has a (STR_ID, MF_LANGUAGE_ID) primary key...

  • Creating an EJB that has no primary key

    I want to create an EJB for a table that has no primary key using
    J-developer but I get an error like this :
    "cmp-field of type 'java.lang.Long' does not have a no-arg constructor which is needed for properties/fields based mapping"
    How can I go on?

    Sorry primitives are NOT allowed to be primary Key candidates - OOPS!
    it looks like you may have to use String
    or provide your own Primary Key class which (perhaps) extends Long

  • How to make a form using a wizard when the table has no primary key ?

    Hi,
    I want to make a form to update, delete a table. The table has no primary key. The problem is that the Wizard ask for a primary key.
    How to avoid using a primary key ? i mean I don't want to create a primary key if is is possible.
    I would like to use the wizard; is it possible ?
    Thank you for your kind answers.
    Christian

    I believe the key is choosing 'Interactive' as opposed to 'Classic' in the implementation and then you can choose 'Existing Trigger' for the primary key source and it should work to use an existing column as your proimary key.

  • Need to create form on a table with report with a table has NO primary key

    Hi, I tried to created some insert/update/delete form+report in an application, it works fine only if the table has primary key. Does anyone know how to create the same functionality with a table with no primary key? I saw an application is built on older version of htmldb that is using tables with no primary keys at all.
    Here are the specific issues that I am facing:
    - I am building some Form on a table with Report, it requires the table with primary key for form to update. Is there a workaround that I can use tables that has no primary keys at all?
    - Say if primary key is necessary in the previous report+form, but the maximum number of columns that I can use to composed a primary is only 2 for that Form-Report, I cannot find anything handling > 2 primary key. Do you know if there are some ways to composite a primary key from many columns together?
    Your help is really appreciated.
    Thanks,
    Angela

    Sorry to ask response so late. I had no time to get back to that issue before.
    Regarding the triggers, I can make it work for the update, but not the insert.
    Here is my trigger:
    create or replace trigger STATUS_T1
    instead of insert on STATUS
    begin
    insert into STATUS ("LABEL", "AREA", "OWNER", "TEST_NAME", "STATUS", "REMARKS", "BUGS", "DEV_MGR", "TEST_BY_DATE")
    values(:new.LABEL, :new.AREA, :new.OWNER, :new.TEST_NAME, :new.STATUS, :new.REMARKS, :new.BUGS, :new.DEV_MGR, :new.TEST_BY_DATE);
    end;
    by any chance, you can notify what is wrong?
    I already skip the ROWID when inserting to the view STATUS, but I cannot figure out what is wrong when inserting a new record to that view.
    It gave me the following errors:
    ORA-06550: line 1, column 38: PL/SQL: ORA-00904: "ID": invalid identifier ORA-06550: line 1, column 7: PL/SQL: SQL Statement ignored
    Error Unable to process row of table STATUS
    Then, I turned to debug mode, I am thinking that maybe because I use a HIDDEN item to hold the value of ROW_ID as I use the rowid (called ID in the view) to retrieve the record as a column link from previous page. What do you think?
    Thanks again,
    Angela

  • Error: has no primary key specified. It should define either an @Id, @Embed

    I'm using toplink with JPA. it was able to deploy to OC4J succesfully. however, when I deploy to oracle application server 10.1.3, I got the following error:
    has no primary key specified. It should define either an @Id, @EmbeddedId or an @IdClass.
    I do have @Id defined for id property. I tried to move @Id annotation to getId() method, instead of id property, the deployment succesfully.
    I have many entities need to be changed. i'm wndoring if there is configuration or if it is bug of OAS 10.1.3

    Hello,
    You haven't mentioned which version of OC4J you are successfully deploying to. If it is not 10.1.3, then you might try upgrading your OAS server so that its version matches the OC4J version you are using. OAS 10.1.3 only had very limited JPA support, and so it is advisable to use OAS 10.1.3.3 anyway.
    Best regards,

    you will have to create a sequence and a trigger
    CREATE SEQUENCE <SEQUENCE NAME>
    INCREMENT BY  1
    START WITH  1
    NOCACHE
    /this sequence will guarantee that each requested number is unique
    the trigger will select from this sequence and insert the obtained value in the new record
    CREATE OR REPLACE TRIGGER <TRIGGER NAME>
    BEFORE INSERT ON <TABLE NAME>
    REFERENCING NEW AS NEW OLD AS OLD
    FOR EACH ROW
        BEGIN
            select
                <SEQUENCE NAME>.nextval
            into
                :NEW.<COLUMN NAME>
            from
                dual;
        END;
    [/CODE]
    this will always take the value from the sequence, even if you already provided a value yourself
    (otherwise you will first have to test if :NEW.<column name> is null, but I wouldn't do this for a key column.
    if you need the generated key back for further processing (inserting it into a child table for example), you can use the returning clause on the insert statement
    see the oracle documentation for more information about sequences, triggers and the returning clause

  • CMP entity bean with compound primary key

    I'm trying to use a compound primary key in a CMP entity bean. I've created the custom primary key class okay, and I have the prim-key-class set in ejb-jar.xml. My client app gets the home reference okay, but when it tries to find an entity, I get the exception "SQLException: Incorrect syntax near '/'."
    I think I'm having trouble deploying this in OC4J. Is there a sample orion-ejb-jar.xml deployment for a custom, compound primary key somewhere?
    Many thanks for any help.

    Never mind. I solved my problem. Thanks.

    could anyone help me ?
    thanks in advance...

    That's why you should use PreparedStatement instead of Statement. Its setString() method will escape that value for you properly when you bind it.

  • Unable to create new entry in table that has no primary key

    Hi
       I have a table which is required to have no primary key (except mandt). After i generate table maintanance, when I go to create new entries, the table control to enter the new values does not appear. When I click on edit->new entries, it goes back to the fields tab of the table. Same when i check through SM30.
    If i maintain atleast one primary key, I am able to get the table control in new entries screen. However the requirement permits no primary keys except mandt. How can this be resolved?
    Thanks

    Hi,
    THE PROBLEM WITH UR TABLE IS
    YOU HAD DECLARED MANDT AS THE PRIMARY KEY AND THERE IS NO OTHER KEY IN UR TABLE
    iT'S NOT ALLOWING YOU TO ADD NEW ENTRIES BECAUSE MANDT IS THE ONLY PRIMARY KEY IN YOUR TABLE AND IT WILL HAVE A DEFAULT VALUE BASED ON THE CLIENT. SO  IT'S NOT SHOWING YOU THE CREATE NEW ENTRIES OPTION.
    SO TRY TO PUT ONE MORE FIELD AS THE PRIMARY KEY SO THAT YOUR PROBLEM WILL SOLVE VERY EASILY  ALSO MAKE SURE THAT TABLE IS ACTIVATED.
    REVERT IF U NEED SOME MORE HELP
    Thanks &Regards.

    Thanks,
    DeepakGood database design will always require a PK on the tables. There are only very few and rare expetions to this rule. One would be when you have store the data only temporarily in this table, like it is often done for import/loader tables. The data is first loaded in the "import"-table, then validated and then transported to the "real" tables. In such a scenario you can ignore the primary key on purpose. Because you already have a UK on this table it can't be such a scenario.
    For most other scenarios you should always add a PK. Ask critically why there is no PK on it. Is there a reason for it or was the table designer just not doing its job well?
    Btw: A UK is identical to a PK if the column is mandatory (NOT NULL). In this case you could simply change the constraint from UK to PK.

  • Entity Object with Nullabl Primary Key Parts

    I posted an article on how to handle nullable PKs.
    Here is the link:
    http://radio.weblogs.com/0123729/stories/2003/05/15/entityObjectOverTableWhosePrimaryKeyMayBeNull.html
    Please take a look if you're interested in the topic.

    Most likely the record in the database has an extra white space attached to it.
    For ex:- 'Harry ' instead of 'Harry';
    If you have an extra space there then findByPrimaryKey("Harry") will not be find that record.
    You can test it launching a SQL*PLUS
    and
    select col from table
    where col='Harry'
    this would return "no rows found" if it has an extra white space.

    Exception Description: Entity class [class model.Test] has no primary key specified. It should define either an @Id, @EmbeddedId or an @IdClass.
    Actually, every row of oracle table has a ROWID field , I think it is a good “primary key field”. Add it into Entity Java bean file as following:
    @Id
    private ROWID rowid;
    And generate accessors, ok, run……
    GOOD, No problem.
    But when you insert a new row, got an exception:
    Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2006.8 (Build 060829)): oracle.toplink.essentials.exceptions.DatabaseException
    Internal Exception: java.sql.SQLException: ORA-00928: missing SELECT keyword
    Error Code: 928
    Call:INSERT INTO TEST (ROWID, B, A) VALUES (?, ?, ?)
         bind => [null, 555, 555]
    Query:InsertObjectQuery(model.Test@40979b)
    555~~~, what happened?! Somebody builds a wrong SQL …
    Don’t worry! I know (…) where is the “bug”.
    Find out the class
    oracle.toplink.essentials.internal.expressions. SQLInsertStatement
    which is included in the toplink-essentials.jar,
    decompile… , fix…, compile, and jar it back.
    Fix
    if(field.getTable().equals(getTable()) || !field.hasTableName())
    to
    if((field.getTable().equals(getTable()) || !field.hasTableName()) && !field.getName().equalsIgnoreCase("ROWID"))
    OK, it is running well.
    I suggest ORACLE fix it into his next version. Do you think it is a good idea?

    Do you think it is a good idea? Not really, but that's just my two cents.

  • Deploying BMP Entity Bean with primary key calss

    Hi,
    I am using EJB 2.0 with and websphere studio 5.0 and database is sql server 2000.
    My BMP Entity bean has a primary key class.From my client I am invoking the Entity Bean by calling it's findbyprimarykey method.
    The home interface of my findbyprimarykey method returns a class of type Remote.But in the Entity Bean class,the return type is the primarykey class type.
    My problem is invoking this findbyprimarykey from the client to get the remote interface so that the other business methods of the entity bean can be called.
    The control goes into the ejbFindbyPrimaryKey but when it is returing from the Entity Bean class,it gives a remote exception (as the return type in Entity Bean class and Home interface are different for the findbyprimarykey method).
    I think that somewhere in the deployment decriptor in my websphere,i have to specify the primarykey class type,which i am missing out and hence getting the error.
    Please help me out with your advice and solution.
    Thanks

The issue I am running into when trying to run the application is: Exception Description: Entity class [class com.persistence.Rpthead] has no primary key specified. Note: I get a simular error when using toplink directly.
    The tables I am binding to do not have primary keys defined. They use unique constraints to manage the table integrity.
    Is it possible to use EJB 3.0 on tables without a primary key? If not, are there plans to support this in the future?

    The spec requires a primary key Id annotation. I will take your suggestion to EJB 3.0 expert group.
    Can you also send an email to [email protected] with your requirement?
