Thanks &Regards

Hello,
EclipseLink has support for database object-relational datatypes, but they are not supported or exposed through JPA. Instead, you will need to leave it unmapped and then change the mapping, using a customizer to create the mapping described:

How to transfer database table contain null values, primary key, and foreign key to the another database in same server. using INSERT method.

how to transfer database table contain null values, primary key, and foreign key to the another database in same server. using INSERT method. thanks

INSERT targetdb.dbo.tbl (col1, col2, col3, ...)
SELECT col1, col2, col3, ...
FROM sourcedb.dbo.tbl
Or what is your question really about? Since you talke about foreign keys etc, I suspect that you want to transfer the entire table definition, but you cannot do that with an INSERT statement.

Table creation from type - Primary key with 2 columns

Hello,
I have to create a table from a type that I created.
The thing is that I want to create a primary key using two column.
Because this table is junction table.
How can I do this ?
CREATE TABLE CONTENT OF CONTENT_T (ID_COMP primary key, ID_CHAR_J NOT NULL PRIMAR
Y KEY);
Oracle return:
CREATE TABLE CONTENT OF CONTENT_T (ID_COMP primary key,ID_CHAR_J NOT NULL PRIMARY KEY)
ERROR at line 1:
ORA-02260: table can have only one primary key
So I tried:
CREATE TABLE CONTENT OF CONTENT_T (ID_COMP,ID_CHAR_J NOT NULL PRIMARY KEY)
ERROR at line 1:
ORA-02338: missing or invalid column constraint specification
Tahnk's in advance.

How to find out the primary key column of a database table?

Hi
Given the following scenario :
Given an inputfield, the user can enter a table name. The code behind will base on the table name given and extract out the fieldname of the primary key and concatenate the two field to become a unique string.
Eg. Order ID and Product ID make out a primary key.
How do i achieve that? Any code sample?
Regards,
Rayden

Check the below code :
REPORT zTest no standard page heading.
data : i_DD03P like DD03P occurs 0 with header line.
data v_table like DCOBJDEF-NAME.
parameters : p_table like dd02l-tabname.
start-of-selection.
v_table = p_table.
CALL FUNCTION 'BDL_DDIF_TABL_GET'
EXPORTING
    NAME                = v_table
   STATE               = 'A'
   LANGU               = 'E'
IMPORTING
GOTSTATE            =

DD09L_WA            =
TABLES
   DD03P_TAB           = i_DD03P
DD05M_TAB           =
DD08V_TAB           =
DD12V_TAB           =
DD17V_TAB           =

IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
loop at i_DD03P.
if i_dd03p-KEYFLAG = 'X'.
write:/ 'Key fields', i_dd03p-FIELDNAME.
endif.
endloop.

How to find out the primary key of oracle apps tables

Hii,,
My Question is How to find the primary key in the apps table...Is there any Query or other way to find out???
for eg.
I want to find out the primary key of the AP_INVOICES_ALL table...just tell me how can i get the primary key of this table.
I am currently using toad for the query..
Please guide me...

you can define the primary key when you create table
or add the primary key after the table creation by 'ALTER TABLE ... ADD constraint pk_nme primary key (col1, col2)';
you could use below sql to check the detail of primary key:
1) check out the table definition directly:
select dbms_metadata.get_ddl('TABLE','EMP') FROM DUAL;
2) check out the columns of primary key:
select * from user_constraints where constraint_type='P' AND table_NAME='EMP';
select * from user_cons_columns where CONSTRAINT_NAME='PK_EMP';And BTW, it is madam, not sir. :)

How to map 2 tables together into a new one, like an Union?

Hi.
I am new in Oracle Data Warehouse Builder and what I'm wanting to do could be simple.
My question is: How to map 2 tables into a new one? That is, what I need is to do a Union.
See the following tables:
What I have is:
---------------+ ---------------+
| A | B | | A | B |
|--------------- |---------------
| 10 | 34 | | 13 | 39 |
---------------+ ---------------+
Table 1 Table 2
What I wish is:
---------------+ ----------------------+
| A | B | Original table |
|--------------- ----------------------+
| 10 | 34 | 1 |
|--------------- ----------------------+
| 13 | 39 | 2 |
|--------------- ----------------------+
Then, I need put all data together into a new table and this new table should has a new column showing the original source of data to each record.
Can I do such thing?
I'm using the Oracle Warehouse Builder and trying to do a map in this way.
Any hint will be very helpful. I also will appreciate an indication of some document which can show how to do it.
Thanks .
Rodrigo Pimenta.

Use the SET OPERATOR. That should help i guess.

Primary Key With Four Column ,How to use that Column As Primary Key In Form

Dear All,
i have create composite Key as primary Key With Four Column .
How can i use these column in Form With Report Page.
How can i use these four Column as primary Key to Edit Record .
How can i do this.
Thanks

wrap a view around your table with this bogus primary key. Use an instead of trigger to handle the inserts and updates. And then look at using surrogate keys to resolve these bad design issues...

Time Zone Conversion with out using function and with out alter

Hi All,
I am able to see 1Hr difference in my date fields of SQL output because in UI (User Interface) date field was stored in BST format but DB time zone is in GMT format so can any one help me to find a solution for 1 hr difference, here i don't have Privileges to alter DB time zone and i couldn't use function as i have so many SQL's and can't apply that function manually. SO is there any other option to change the DB time zone with out alter it and with out using function.
Thank you Very Much.

Hi,
you need to set time zone in your session, let's do an example :
alter session set nls_date_format='DD/MM/YYYY HH24:MI:SS';
CREATE TABLE USERA.T
SDATE       DATE                              DEFAULT sysdate,
WITHOUT_TZ TIMESTAMP(6)                      DEFAULT sysdate,
WITH_TZ     TIMESTAMP(6) WITH TIME ZONE       DEFAULT sysdate,
WITH_LZ     TIMESTAMP(6) WITH LOCAL TIME ZONE DEFAULT sysdate
insert into USERA.T(sdate) values(sysdate);
commit;
select * from USERA.T;
SQL> select * from system.t;
SDATE
WITHOUT_TZ
WITH_TZ

How do I Create an AutoIncrement on a Primary key Default

I am new to Oracle and need to know how to create a table that uses an automatic incrementation on a primay key for it's default. I need the uniqueness automatically managed by the DBMS.. This activity is know as setting the Column (primary key with identity) in Ms-SQL..
Your help would be appreciated greatly....
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

How do you change the value of the primary key in the CMP?

Hi,
The cmp that I built has the phone as the Prikey field.
The bean has the get/set methods. The servlet invokes the cmp
to change the phone number. How could I do that?
The setXXX for the priKey can not be called outside of the ejbCreate() so
how would I change the prikey value of a particular row of the table. Do I have
to remove the bean then create the new bean with the new priKey value?
Please help,
Thanks

Thanks Mona
Tom.

Hi TOM,
The primary key is the unique identifier of an Entity Bean.
To change it, you have to remove the bean instance = database delete
then you have to create a new one with the new primary-key value =
database insert.
Hard luck tom, maybe you should consider changing your primary key. You
can easily change it to an AutoNum

CMP with auto-increment primary key.Please help

Hi all,
I new with EJB technology so please bear with me.
Env: 2k Server, SQL 2k Server
Sun One(Forte EE) to develop and deploy CMP
I got the servlet to load the data from CMP's business mehods
is fine. Calling the findPrimaryKey is OK too. Even when I try to insert the row into DB is OK. At this time I make key PK is int AND NOT
AUTO INCREMENT everything is OK. In the ejbCreate method
I called setPK, setName ...It's fine.
The problem comes when I try to make the PK(still int) to be auto-increment field.In ejbCreate not call setPK because of in SunOne IDE, under the J2EE RI tab of EJB Module property, the Auto generate SQL I set to false so that I can
modify the SQL statement under SQL Deployment.createRow not taking the PK. I thought that will do it but it doesnot like it at all (I got Exception with transaction rollback)I just want to insert a single row with ID and name that's all.
Then I changed the SQL statment take PK and changed the Auto Generate SQL to True and in ejbCreate the PK as one of the args and called setPK this time with null object. It doesn't like neither.(Exception Cannot set the primary key with null. That is reasonable.)
I thought using EJB fast and clean technique would help developer to develop application with easiness.
So I realy stuck with this, I wonder ejb 2.0 support for auto increment at all because I would like to take advantage of the auto increment feature of the DB without writing the PrimaryKeySequence generator at all.
Am I missing something with this? May be just config thing to tell
that my PK is auto-increment field so that when the ejbCreate called it knows not taking the PK or even not asking to call setPK in ejbCreate.
Any help would appreciated.

Creating a primary key with the parallel option and the tablespace option

I know I can create a unique index with these options and then make the primary key with the "using index" clause. anyway to do this and skip the create unique index and just create the primary key ?

Database Adapter Merge with char/varchar primary key

Hi guys,
It seems as though merge statements in BPEL database adapters do not work if the primary key of the table contains a char/varchar. This is in Jdeveloper 10.1.3.4.0
If I create the table below:
create table test_merge (
id        number primary key,
text      varchar2(255)
);Then the merge operation will update and insert as expected. However, if I create the same table but with id as a char/varchar, then the merge statement will never update.
It seems like it never finds a record with the same id (if it is a char/varchar), and always attempts to insert, which results in unique key constraint errors for the primary key column.
Has anyone else encountered this issue and found a way to get the merge statement to work correctly? I can obviously perform the select myself, and then conditionally update/insert, but I would prefer the merge to work as expected.
Thanks

After investigating further, it seems that even a database adapter select is not working correctly. Consider the following table:
create table test_merge (
id        varchar2(255) primary key,
text      varchar2(255)
);And I have inserted a record with id = "1" and text="abc"
If I create a BPEL process and add a database adapter (with only the select checkbox ticked) with the following SQL:
SELECT ID, TEXT FROM TEST_MERGE WHERE (ID = #id)If I invoke this adapter, passing in "1" as the id, then a record is returned, with the correct text (i.e. "abc") BUT the id returned is "-9900000000000000000000000000"
Can anyone explain why this is happening?
