EJB with no primary key?

I have an EJB with two fields, timestamp (Date) and entry (String). It's possible for two fields to have the same timestamp, so I can't use it as the primary key. Is it possible to just say there isn't a primary key, or do I have to do something tricky?

I'd be a little easier about it if the page you pointed to didn't show the DAO being accessed from an -entity- bean ..
I think I'm going to stick with an auto-incrementing key. I think I might use another EJB to keep the count, which maybe I can re-use across all my other applications. My only worry is about performance, because I'm going to be getting the current count every single time I create a new log entry. Though .. I think it'll be pretty efficient, I'm going to assume the EJB I use for the count doesn't update the database every single time I increment it.
Either that, or I could be tricky and wait a millisecond if the date I get is the same as the last one. ;-)

  • Duplicate record with same primary key in Fact table

    Hi all,
       Can the fact table have duplicate record with same primary key . When i checked a cube i could see records with same primary key combination but the key figure values are different. My cube has 6 dimentions (Including Time,Unit and DP) and 2 key figures. So 6 fields combined to form the composite primary key of the fact table. When i checked the records in se16 i could see duplicate records with same primary key. Ther are no parallel loading happening for the cube.
    BW system version is 3.1
    Data base is : Oracle 10.2
    I am not sure how is this possible.
    Regards,
    PM

    Hi Krish,
       I checked the datapacket dimention also. Both the record have same dimention id (141). Except the Keyfigure value there is no other change in the Fact table record.  I know this is against the basic DBMS primary key rule. But i have records like this in the cube.
    Can this situation arise when same records is there in different data packet of same request.
    Thx,
    PM

    Any Idea?
    Thanks in advance

    What happend when two concourrent user try to get the same key on the table? If for example I have 30 users at same time do I have lock table?
    Any way here the finest log using sunone 8. The error is the same, so I think I missing something:

  • Insert values of form on a table with compound primary keys in APEX

    Good evening,
    I have a table with compoud primay keys. On ER model I had a many to many relation and when I coverted to relational model I've got a table with the primary keys of the two entities.
    My problem now is that I am trying to build an APEX application with a Form/Report and I want to insert a tuple both on the "entity" and on the table with two primary keys.
    I created a trigger with
    CREATE OR REPLACE TRIGGER ins_key_elem
    INSTEAD OF INSERT
    ON v_key_elem
    REFERENCING NEW AS NEW
    FOR EACH ROW
    BEGIN
    INSERT INTO elem_type (elem_key, type_key)
    VALUES (:NEW.elem_key, :NEW.type_key);
    INSERT INTO elem(elem_key, name)
    VALUES (:NEW.elem_key, :NEW.name);
    END;
    Is that ok? If it is, now how I can use that trigger to do what I need? i.e. insert the tuple on the two tables when I use the create button of the form

    Nevermind...figured it out. Was able to set the value on the Report Attributes page.

  • Updating a table with no Primary key

    What I am trying to find out is if you can uniquely update a single record in a table that has no primary key. I see no way to reference the record I want, other than specifying all the field values in a where clause. This is a problem though, because if I have another record with the same field values, that will get updated too. (I know its a bad database design, but some people do it and I need to work around it!!!), there are some situations where you would have identical records as far as a where clause is concerned, for example, you cant use a blob in a where clause so that might be where your records differ...
    In SQLServer 2000, Enterprise manager throws an error if you have a table with no primary key and duplicate records that you try to update through the GUI. EM uses stored procedures to execute updates, and it rolls back ones which result in more than one update result.
    Im not too familiar with Cursors in SQL, only that they are quite slow and not implemented on all DB products. But I think that they might be able to solve the problem (but I dont logically see how).
    Can anybody explain this to me?

    another record with the same field valuesIf you have two records and all the field values are the same then the records are logically the same anyways, so it shouldn't matter if you update both (one would question why there are two records in the first place.) In other words there is no way, either computationally or manually to tell them apart.
    I suspect that that is rather rare. Instead what is more likely is that you are only using some of the fields. So just keep adding fields until it is unique.

  • DBMS_CDC find only the columns that are changed along with the primary key in the table

    Hello,
    We are having a requirement to find the change data in the production environment.
    We are planning to use the DBMS_CDC utility.
    But for  example in the create change table 1 picked emp_id,ename, address, salary,dob.
    I have a sample data of
    empid
    ename
    address
    salary
    DOB
    1
    test1
    24 test street
    2000
    20-Jan-98
    2
    test2
    25 test street
    2500
    15-Aug-97
    if ename for empid 1 is changed to test1_test3 from test1.
    My CDC is capturing  the values in the old and new values in the 5 columns.
    But i need to get only the empid (primary key of the source table) and the ename column as only that's been updated not the rest of the 3 columns.
    Can i accomplish this.
    Please advice.

    Hello,
    Thanks for the information.
    but if i change the change table  then i will miss the other columns right?
    I want to get the columns( empid and ename) only if ename is changed. i.e when ever any column in emp table changes i need to get all the columns where the data is changed along with the primary key columns empid.
    Is there any way i can tweak the parameters so that i can achieve this or is there any other way using the cdc i can get this data.
    Thanks

  • How to Work with Composite Primary Key

    Hi All,
    I'm working with Toplink JPA. Here I have A problem with inserting into database table which have composite Primary Key.
    What I'm doing is, I have two tables. to maintain many to many relation between these two tables I created another intermediate table which consists of foreign Keys (reference) of above two tables.
    Now these two foreign Keys in the Intermediate table made as composite Primary Keys.
    When I'm trying to the data in the Intermediate table I'm getting the foreign Keys values are null..
    could anyone suggest me how to work with composite Primary Keys

  • Mapping tables with no primary key defined

    Hi!
    I was just wondering if it's possible to map a table with no primary key? The reason why is that I have a logging table that I want to access, which is built very simple and the only useful filtering criteria that I'll be using there is a date column.
    Regards,
    Bjorn Boe

    TopLink requires that an object have a primary key to determine identity, perform caching, and database updates and deletes. It is best to define a primary key in all your objects; a sequence number can be used if the object has no natural primary key. The primary key does not have to be defined on the database, as long as a set of fields in the table are unique you can define them to be the primary key in your TopLink descriptor.
    If your table truly has no primary key, nor unique set of fields, it is still possible to map the table with some restrictions. If you disable caching, and mark the object as read-only, and never update or delete the object, you can map it for read-only purposes.
    You will need to do the following:
    - Set any field as the primary key to avoid the validation warning.
    - Set the cache type to NoIdentityMap.
    - Set the descriptor to be read-only.

  • FindByKey with Composit Primary key

    Hi
    View Object based on Entity Object. Database table defined with Composit Primary Key.
    I have to query ViewObject using findByKey().
    Can any one help me how to use findByKey() using a composit primary key in ADF 11g.
    Thanks

    Hi,
    this is covered in the developer guide here:
    38.1.7 Understanding When You Can Use Partial Keys with findByKey()
    http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcadvvo.htm#ADFFD1189
    The key thing is to have your object types casted correctly or else null for your composite key.

  • FindByKey with tow primary keys

    I am using findByKey in a table with two primary keys. It works fine if I use only one key in the ViewObject, using either of the two keys, but I need to use both keys, but search on the value of only one of them.
    I read I could pass null as the value of the other key, to consider all the values on it, but it doesn't work.
    Both keys are String.�Any suggestions?
    Thank you.

    Victoria:
    Please run your test case with diagnostic turned on. It will show the SQL statement used for your findByKey() request. See if the SQL makes sense. If still doesn't work and if you cannot figure out what's going on, please post the diagnostic output.
    To turn on diagnostic, you need to specify
    -Djbo.debugoutput=console
    as one of the JVM switches.
    If you're invoking your app (middle-tier app) from command line,
    include -Djbo.debugoutput=console as in
    java.exe -Djbo.debugoutput=console ...
    If you're running your app from within JDev:
    1. Select the project.
    2. Do right mouse click and select "Project Settings..."
    3. On the Settings dialog, select Configurations/Runner.
    4. In the righthand side pane, you should see a textbox for "Java
    Options". Please add the following JVM switch:
    -Djbo.debugoutput=console
    Then, rerun. The run command should include
    -Djbo.debugoutput=console as in
    "D:\JDev9i\jdk\bin\javaw.exe" -Djbo.debugoutput=console -classpath ...
    You should now see a lot more output on the IDE's message window.
    Thanks.

    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

  • Help.......... required :Database table with no primary key

    Hi All,
    I have a table sponsor_logos whose structure is as follows:
    sl__sponsorid number,
    sl__clubid number,
    sl_hallno varchar2(7) not null,
    sl_logofilename varchar2(100) not null,
    sl_date_modified date not null
    Where in the sl__sponsorid and sl__clubid are foreign keys and I do not have any primary key for the table.
    I need to insert into and also delete records from the table.
    I have gone through various topics in the java forum for EJB's to find out what design strategy should I use?
    Some say that if a table does not have primary keys, and if the table is represented by a CMP entity bean all the fields of the table are considered as a part of primary key.In that case what would my code look like and what would my deployment descriptor contain?????
    According to the specification, the CMP or a BMP represents a unique record in a database.In that case should I be using a Session bean to handle insertions and deletions for the table?
    Since this is my first project with EJB's I am really confused as to what design should I be using for this situation. Since I have a time constraint I can't take a long time to decide on what strategy I should use.
    Suggestions regarding this are welcome .

    Hi Maris,
    I have my PK class ready with all the fields in it.
    Deployment descriptor ready with <prim-key-class>package.SponsorLogoPK</prim-key-class>
    . According to descriptor specification there is no need to have an entry for
    <primkey-field>bookingSlNo</primkey-field>
    in case of custom primary key .
    So I have omitted <primkey-field>bookingSlNo</primkey-field>
    I have used the verifier tool and verified the ejb , no errors with regards to this ejb, but , getting errors while deploying:
    An error has occurred.
    Deployment Error -- Error while running ejbc -- Fatal Error from EJB Compiler -- JDO74025: JDOCodeGenerator: Caught an Exception validating CMP bean 'SponsorLogoBean' in application 'resnet_ejb' module 'E:\Sun\AppServer\domains\domain1\applications\j2ee-modules\resnet': JDO72335: If the table SPONSOR_LOGOS for the bean corresponding to the generated class com.resnet.squash.api.entity.SponsorLogoBean483209734_JDOState is mapped as the primary table, it must have a primary key. Choose a different primary table or verify that the contents of the schema file are correct.
    Now what could the problem be . Do I need to do any other setting in the descriptor. I have the cmp-mapping also intact.
