JDeveloper 9i, Foreign Keys and LOVs.

Greetings all,
I'm using Jdev 9i to try and create some maintenance applications quickly. These applications are pretty standard; insert, update, delete, some validation, including foreign keys.
The problem is, I can't figure out how to get JDev to generate the JSPs with LOV pages on the foreign keys.
I've tried setting the validation properties of the entity object to validate from a query, as well as, tried using View objects for the same validation. Neither get me results.
I've also tried embedding the LOV directly using the LOVInputSelect (or whatever it is called). That works partially by displaying a field and a button, but when I click on it, I get an error with no explanation. Very helpful.
I can use a InputSelect datatag, but it is not the best choice for foreign keys with hundreds of values.
Also, since the Wizards are generating the DataEdit tag for the JSP I'm using, it appears that I cannot override them to display the LOV. They display a Calendar page for dates, automatically, but won't display an LOV for referential integrity. At least, I can't figure out how to make them.
Thanks in advance.

It's really beyond me why Oracle haven't provided a fairly complete set of Renderers (and a bit more BC4J oriented than the one's mentioned in the HOWTO).
Basically, you have two choices:
1/ develop your own Renderers (make your own conventions with Properties on Entities/ViewObjects) and use InputRender
2/ generate the JSP's yourself using the usual jbo tags (probably again based on some meta data in the properties). You may have to fiddle around a bit with inputselectlov etc.
Again, it's hard for me to understand why Oracle haven't substantially improved their default generated BC4J JSP pages, it looks to me that it is not so hard (compared to some of the other things they're trying to pull off) and gives maximum benefit for the customers.
Alternatively, there is JHeadstart (do a search on otn, you'll find some pointers). It generates lots of screens nicely for you (a la Designer, if you're familiar with that). Some teething problems, but really very productive otherwise. The disadvantage here is that if you want to start to make a few little changes outside what it supports, you're up against a fairly steep learning curve to master UIX and MVC framework. Apparently there's some hope that they will generate to Struts (taglibs & controller, if I understand well) soon.

    I cannot create a namedquery on my secondary table. The method for the column uses the entity object rather than the name and value of the column.
    For instance,
    (Coketruck) table has inventory records(Products) table
    Coketruck has one to many to the Products table
    Products has a many to one to the Coketruck
    I need to return the products from the product table based on the CokeTruck but I cannot create a namedQuery because the method in the Product table is an entity object type instead of a long that I can use to look up all the products based off the column truck_id.
    This is what I was expecting…
    Private Long truckId;
    public Long getTruckId() {
    return truckId;
    public void setTruckId (Long truckId) {
    this. truckId = truckId;
    Instead this is what I have…
    @JoinColumn(name = "TRUCK_ID")
    private Coketruck coketruck;
    this. coketruck = coketruck
    public Coketruck getCoketruck() {
    return coketruck;
    public void set Coketruck (Coketruck coketruck) {
    this. coketruck = coketruck;
    How do I do a query on the Product table to return all the products that are in the coketruck?
    If I do the following it expects for me to pass the Entity Object which I cannot use as search criteria for my find method.
    @NamedQuery(name = "Products.findById", query = "select o from Products o where o.truckId = :truckId")
    On a different note but the same song…
    I noticed that when I look at my Session Bean Data Contols that the coketruck already has a list of the products. I have created a jsp page with a backing bean and have been able to use the namedquery on the coketruck entity to retrieve the productList. Unfortunately I need to sort the products by type and was also not able to find where to perform the work to be able to iterate through the productList to get my desired display. Therefore I started looking at doing another namedquery that would only retrieve the product_type ordering by the truckId.
    Seems I have come full circle… I don’t care what method I have to use to get the info back.
    Any help is greatly appreciated!

    I work on an application wich uses a shopping cart stored in a database. The shopping cart uses two tables:
    CART: Holds information common for one shopping cart: the user it is connected to etc.
    - Primary key: CART_ID
    CART_ROW: One row in the cart, e.g. one new product to buy.
    - Primary key: ROW_ID
    - Foreign key: CART_ROW.CART_ID references CART.CART_ID
    From the code the rows in the cart are collected per cart, as is modelled by the foreign key. There exists one more relationship, which we use in the code, but which is not modelled by a foreign key in the database. One row can be dependent on another row, which makes the other row a parent.
    CART_ROW has a column PARENT_ID which references CART_ROW.ROW_ID.
    Should we add a foreign key for PARENT_ID? Or are there any questions to consider when it is a foreign key to the same table?
    I suggest to add foreign key it wont harm the performance (except while on insert when there would be validation for the foreign key). But it would prevent users to insert wrong/corrupt data either through code or directly by loggin in the database.
    A while ago we added indexes, both on ROW_ID and on PARENT_ID. Could the index on PARENT_ID have been harmful, since there is no foreign key?
    Index on parent_id would only be harmful if you do not make use of index after creating it (i.e. there is no query which make use of this index).
    And if you decide to have a foreign key on parent_id then I suggest to have index too on parent_id as it would be helpful atleast when you delete any record in this table.
    Best regards!

  • Lack of Primary and Foreign Keys and Efficiency

    I am reverse engineering a Maximo database. I am shock that it does not have Primary or foreign keys define for 590 out of 620 tables.
    My question is does the lack of Primary and Foreign key relationships adversely impact the efficiency of an Oracle database? I think it does IBM techs do not think it does.
    Anyone has the answer?

    does the lack of Primary and Foreign key relationships adversely impact the efficiency of an Oracle database? Not necessarily. There are many large OLTP databases that do not define PKs and FKs.
    It is true that the presence of constraint defintions is used by the optimizer. However,
    what matters is how the application is written and how the optimizer handles it.
    Remember that Oracle Databases have been in production since before constraint definitions were introduced.

  • Foreign Keys and import of tables (ORA-02297)

    How can i get all the foreign keys for a particular schema, basically i'm trying to import tables into a particular schema so i'm trying to disable the constraints, truncate the table , import data and then enable the constraints.
    but i'm having error like these when i disable all the constraints in this particular schema
    Table altered.
    alter table STANDINGS disable constraint P_STANDINGS
    ERROR at line 1:
    ORA-02297: cannot disable constraint (SCDAT.P_STANDINGS) - dependencies exist
    alter table STANDPMTS disable constraint P_STANDPMTS
    ERROR at line 1:
    ORA-02297: cannot disable constraint (SCDAT.P_STANDPMTS) - dependencies exist

    I use a dynamic SQL-Plus script to generate all the constraints for a schema. I then run this SQL to disable the constraints. Sometimes need to run the script more than once depending on the order the constraints are disabled. Once your scripts runs clean, then you can truncate your tables, import your data, and re-enable constraints.
    To re-enable, just use and editor to do REPLACE DISABLE WITH ENABLE....
    Here is sample of my dynamic sql. Needs to be run as SYSDBA...
    set heading off;
    spool c:\disable_constraints.sql;
    select 'ALTER TABLE ' || owner || '.' || table_name || ' DISABLE CONSTRAINT ' || constraint_name || ';'
    from dba_constraints
    where owner = '<owner_name>';
    spool off;
    Hope that helps..

  • Foreign key and index

    In our table:
    Table Name:
    X12IN CLOB
    We have a foreign key on the USERID column. And this column appears in the WHERE clause always.
    I wanted to know in addition to the foriegn key constraint, putting an INDEX on the USERID column will help query performance?
    Generally speaking:
    I wanted to know whether in oracle putting a foreign key constraint on a column creates an INDEX automatically or do I put the index specifically besides the FOREIGN key.
    Thanks in Advance,
    Rumpa Giri

    Oracle does NOT create an index when you put a foreign key constraint on a column, so you need to create one if you want one.
    Have a look at this discussion on asktom to understand when and why indexes on foreign keys are a good idea.
    If your query that uses USERID in the where caluse returns a small number of rows in proportion to the number of rows in the table, adding an index could well help with query performance....but as always, it's best to benchmark it and get some stats that you can then use to make an informed choice.

  • Storage for Foreign Keys and Function based indexes

    This may well be the silliest question of the day, but is it possible to specify the storage for a Foreign key or a function based index? I'm not even sure that it would make sense.

    Well, a foreign key constraint is not a segment, nor is any other type of constraint. However, a function-based index is a segment, just like any other index. So, in that case, specify a tablespace, just like you would with any other index.
    Something like this:
    create index my_fbi on my_tab(upper(last_name)) tablespace my_index_tablespace;

  • HOWTO: get JDev to show the foreign keys in Conn Nav & struct window

    I have SQL tables with foreign keys but the JDev connections navigator and table editor dont show them. They just look like primary keys in the "PK" column. The structure window shows a bunch of constraints with names like "SYS_C00143114" which is not very meaningful to me. Surely JDeveloper knows what these magic numbers mean and can trace the foreign keys for me.
    How can I get JDeveloper to show the foreign keys, and which table is referenced by that foreign key? Can I make it navigate from a table's foreign key value to the the correct tuple in the referenced table?
    Maybe this is an ER if JDev doesn't do this already. Navigating a schema, or drawing it showing all the foreign key references would be very handy. Navigating through actual table data would be nice too.

    I found "new->Database Diagram" that does a lot of what I wanted, at least in mapping out the foreign key references. Now if I can just figure out how to print a .png file...
    It would still be nice for the connection navigator to trace them also.

  • Questions about creating a foreign key on a large table

    Hello @ll,
    during a database update I lost a foreign key between two tables. The tables are called werteart and werteartarchiv_pt. Because of its size, werteartarchiv_pt is a partitioned table. The missing foreign key was a constraint on table werteartarchiv_pt referencing werteart.
    Some statistics about the sizes of the mentioned tables:
    werteart 22 MB
    werteartarchiv_pt 223 GB
    werteartarchiv_pt (Index) 243 GB
    I tried to create the foreign key again, but it failed with the following error (Excuses for the german error message):
    sqlplus ORA-00604: Fehler auf rekursiver SQL-Ebene 1
    sqlplus ORA-01652: Temp-Segment kann nicht um 128 in Tablespace TEMPS00 erweitert
    The statement I used:
    alter table werteartarchiv_pt
    add constraint werteartarchiv_pt_fk1
    foreign key (schiene, werteartadresse, merkmale)
    references werteart (schiene, werteartadresse, merkmale)
    on delete cascade
    initially deferred deferrable;
    So the problem seems to be, that Oracle needs a lot of temporary tablespace to generate the foreign key and I do not know how much and why.
    My questions now are, and hopefully someone is here, who can answer all or a part of it:
    1) Why does Oracle need temporary tablespace to create the foreign key? The foreign key uses the same columns like the primary key.
    2a) Is it possible to tweak the statement without using the temporary tablespace?
    2b) If it is not possible to avoid the usage of the temporary tablespace, is there a formula how to calculate the needed temporary tablespace?
    3) Is it possible to modify data in the tables while the foreign key is created or is the whole table locked during the process?
    Any help or hint is appreciated.

The foreign key uses the same columns like the primary key.Because it's validating the data to ensure the foreign key won't be violated. If you had specified ENABLE NOVALIDATE when creating it then the existing data in the table wouldn't need to be checked and the statement should complete instantly (future data added would be checked by the constraint).

    I have created two new tables as below:
    ZAAVREF (Check table)
    MANDT (PK)
    ZAAV1 (Foreign key table)
    MANDT (PK)
    Then I have created FK on country of foreign key table ZAAV1 and then SE16 (for table ZAAVREF)->Create Entries-> Entered values for Country only->Save....Records entered with valid Country values.
    After that SE16 (for table ZAAV1)->Create Entries-->Entered an Invalid country->Save->Still the record entered to the Database successfully....
    Could you please let me know where I am going wrong.

    shNot really sure i understand your question. If you have 2 data sources and 2 different data types for the same type of data then you'd want to ensure you do a TO_NUMBER on the character representation of the data to ensure you strip out any non-printing characters like tabs or spaces.
    If that's not your problem, please try to be a little more clear. Your subject mentions you have an urgent problem about foreign keys and i find nothing to support your claim of urgency, nor foreign keys, within the subject of your question.

    What business requirement are you trying to meet?
    It's going to be difficult to correctly implement this kind of constraint using triggers, because:
    1. You will need to handle updates on TEST3, not just inserts.
    2. You will need to handle inserts, updates, and deletes on both TEST1 and TEST2.
    3. You will need some sort of locking mechanism to prevent concurrent transactions from violating the constraint (because they can't see the changes that other transactions have made but have not yet committed).
    In other words, it might be on the order 10 times more complicated to implement this kind of constraint using triggers than you originally thought. Before pursuing the trigger approach further, it might be worth looking into some alternatives. Is the benefit of implementing the constraint worth the effort? Are there some "creative" ways you can use declarative (built-in) constraints instead? Would restructuring your tables help?
