Passing Object types using JDBC

I need to pass Oracle user-defined object types in and out of
PL/SQL stored procedures. Is this possible???
Thanks

Hi Tina,
I just had another thought. JDBC for 8.0 doesn't support
user-defined SQL types. This feature isn't implemented until 8i.
Sorry about the false lead!
So you'd have to wrapper your object in another PL/SQL method
which 'explodes' the user-defined type, as:
procedure can_call_from_jdbc (ename varchar2, empno number, ...)
is...
begin
call my_procedure(employee_t(ename, empno, ...));
end;

Inserting oracle objects / collection using JDBC

Hi people,
I want to insert objects with collections(nested tables) into oracle database using my java JDBC. I believe there are two ways, one using strong types and the other as weak. I am using the weak types.
This is what I have got so far:
create or replace type town_ty as object(
name varchar2(20)
create or replace type country as object (
name varchar2(20),
towns town_ty
create table country_tab of country_ty;
Can any one kindly give or show me an example how to insert data into the above table using weak typed JDBC?
Thanks very much

How to pass pricing type using BAPI_SALESORDER_CHANGE

Hi all,
How will we use BAPI_SALESORDER_CHANGE to re-price the orders.
There is parameter LOGIC_SWITCH which can be used to export the pricing type.
But what all are the other parameters we should pass?
Has anybody worked in such a context.?

Hi , Here is what you should pass to update the pricing with a particular pricing type :
1) SALESDOCUMENT = your sales order number
2) ORDER_HEADER_INX-UPDATEFLAG = 'U'
3) LOGIC_SWITCH-PRICING = "your value"
4 ) *order_item_in-itm_number = * the item number for which pricing should be triggered
5) *order_item-inx-ITM_NUMBER = * the item number for which pricing should be triggered
6) *order_item-inx-UPDATEFLAG = * 'U'

How could I Encrypt the data of SDO_GEOMETRY type using DBMS_CRYPTO package

Hi:
I want to Encrypt the data of SDO_GEOMETRY object type using DBMS_CRYPTO package.
What could I do? hope anyone can help me,give me a suggestions!
thanks in advance.
lgs

well, the spatial api would not be able to handle this data anymore, so what you are trying to do is converting an SDO_GEOMETRY to some cryptable user type (see http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_crypto.htm#sthref1506) and encrypting this.
Before using the SDO_GEOMETRY type will have to decrypt and reconvert it again and pass it to the spatial query or function.

Invoking stored procedure that returns array(oracle object type) as output

Hi,
We have stored procedures which returns arrays(oracle type) as an output, can anyone shed some light on how to map those arrays using JPA annotations? I tried using jdbcTypeName but i was getting wrong type or argument error, your help is very much appreciated. Below is the code snippet.

TeamMembersDetailsOT contains the same attributes defined in the OBJ_TEAM_ROLES.

A few things.
You are not using a JDBC Array type in your procedure, you are using a PLSQL TABLE type. An Array type would be a VARRAY in Oracle. EclipseLink supports both VARRAY and TABLE types, but TABLE types are more complex as Oracle JDBC does not support them, they must be wrapped in a corresponding VARRAY type. I assume your OBJ_TEAM_ROLES is also not an OBJECT TYPE but a PLSQL RECORD type, this has the same issue.
Your procedure does not return a result set, so "returnsResultSet=true" should be "returnsResultSet=false".
In general I would recommend you change your stored procedure to just return a select from a table using an OUT CURSOR, that is the easiest way to return data from an Oracle stored procedure.
If you must use the PLSQL types, then you will need to create wrapper VARRAY and OBJECT TYPEs. In EclipseLink you must use a PLSQLStoredProcedureCall to access these using the code API, there is not annotation support. Or you could create your own wrapper stored procedure that converts the PLSQL types to OBJECT TYPEs, and call the wrapper stored procedure.
To map to Oracle VARRAY and OBJECT TYPEs the JDBC Array and Struct types are used, these are supported using EclipseLink ObjectRelationalDataTypeDescriptor and mappings. These must be defined through the code API, as there is currently no annotation support.
I could not find any good examples or doc on this, your best source of example is the EclipseLink test cases in SVN,

Bind problem for varchar2 of object type??

Hello all,
I am trying out binding Oracle Object types to java object types using the SQLData interface.
I created a simple object type called employee with the syntax
create type employee as object (empName varchar2(50),empNo number(9));
I then created a class called EmplyoeeObj which implements the interface. The code for the readSQL and
writeSQL methods are below:
public void readSQL(SQLInput stream, String typeName) throws SQLException {
empName = stream.readString();
empNo = stream.readInt();
public void writeSQL(SQLOutput stream) throws SQLException {
stream.writeString(empName);
stream.writeInt(empNo);
empName is a String and empNo is an int. The code that does the calling is:
String query = "{call test_employee(?)}";
Map map = connection.getTypeMap();
map.put("CISWEB.EMPLOYEE",
Class.forName("test.jdbc.EmployeeObj"));
/*Set back the type map with the new mappings*/
connection.setTypeMap(map);
/*Create a statement to make the call */
ocs = (OracleCallableStatement)connection.prepareCall(query);
ocs.registerOutParameter(1,
OracleTypes.STRUCT,
"CISWEB.EMPLOYEE");
boolean isWorked = ocs.execute();
System.out.println("Execute finished........");
Object outParam = ocs.getObject(1);
System.out.println("Object was obtained........" + outParam);
System.out.println("name:" + ((EmployeeObj)outParam).getName());
As can be seen I have created a stored procedure which has one out parameter. All
this preocedure does is assign an Employee object to the out parameter with a name of
'Alex' and an employee number of 9.
The code runs and all but I get this strange result. In the print I am getting the employee number
coming out correctly but the employee name comes out as 3 question marks. I can't understand why
"Alex" does not out. I have tried different things such as adding a new varchar2 to the object type and new a new integer and what I observer is that I keep getting 3 question marks coming back instead of whatever I assign for the employee name. Could someone please help and let me know what could be wrong?
I have no clue as what is causing this weird behaviour.
Thanks.

Hi,
i have not really a idea. But at the next step i would
try the same procedure with in/out parameter and use a
initialized string. Maybe there is a problem to
determine the length of string.
Bye ThomasThanks for you reply Thomas,
This is the code for stored procedure that I use. As can be seen I just assign an employee to the
out parameter.
CREATE OR REPLACE PROCEDURE test_employee(emp out EMPLOYEE) IS
BEGIN
emp := EMPLOYEE('Alex',49);
END;
Now in the java code when the statement >>
System.out.println("name:" + ((EmployeeObj)outParam).getName());
executes I get the name coming out as the String: "???". That is three question marks. It is very weird. I then attempted to create the object using JPublisher and I get the same result. I attempted not only to use hte SQLData interface but Oracle's ORAData interfaces as well. I went to to create a table with column as the EMPLOYEE type and use in insert to put the same object and and then sellect * from the table to the the and I still get the 3 question marks for the name and the number comes out correctly.
I am not sure what could be causing the text to come out as three question marks. I am using Oracle 9.2.0.4.0 and the ojdbc_g.jar drivers version :9.2.0.3.0. Any help would be greatly appreciated.
Thanks

ERD and oracle object types

Is there a good way to model oracle object types using ERD's in designer 6i. I can only figure out how to map to tables with columns of predefined datatypes (varchar2, number, date, long). I'd like to use designer to create new datatypes. Is this possible? Thanks.

Hi Wiiliam
Sorry for the late acknowledgement (i dozed off!).. Thanks for the response. So the private instance specific to a session ensure that theres no conflict between multiple requests to the same stored proc and hence no conflict of data... Great

New custom object type - SWO1

Hi All,
I need to create a custom object type using SWO1.
The object type needs to be linked to a report program with selection screen(or its tcode).
The selection screen carries just 1field. The output is a new screen.
Would appreciate if any1 can tell me the step-by-step process to accomplish my objective.
-Ram.

Enter a name.
Hit create. Populate the manadatory pop ups don't populate super type.
Blow out the key field. Create a key field.
Blow out the methods - add a method. Add the code for the method - select the method and hit the program button add code as below:
BEGIN_METHOD RUNDUPREPORT CHANGING CONTAINER.
   SET PARAMETER ID 'VPA' FIELD OBJECT-KEY-PARTNEREMPLOYEEID.
export object-key-partneremployeeid to memory id '99'.
   CALL TRANSACTION 'ZEML' AND SKIP FIRST SCREEN.
*object-key-partneremployeeid.
END_METHOD.
Create your event.
My method calls an abap I wrote that is bound to a transaction.
You will need to set the release status for all of the elements of your object and the object itself.
The question I have is why. Are you calling the object in a workflow? If so you will need to use the fm as below:
DATA: OBJTYPE LIKE SWETYPECOU-OBJTYPE VALUE 'ZRM_WWCONT',
    EVENT LIKE SWETYPECOU-EVENT VALUE 'DuplicateEmail',
     OBJKEY LIKE SWEINSTCOU-OBJKEY,
        EVENTID LIKE SWEDUMEVID-EVTID.
    DATA: BEGIN OF EVENT_CONTAINER OCCURS 0.
            INCLUDE STRUCTURE SWCONT.
    DATA: END OF EVENT_CONTAINER.
    OBJKEY = KNVK-PARNR.
    CALL FUNCTION 'SWE_EVENT_CREATE'
         EXPORTING
              OBJTYPE              = OBJTYPE
              OBJKEY               = OBJKEY
              EVENT                = EVENT
        START_WITH_DELAY     = ' '
        START_RECFB_SYNCHRON = ' '
        IMPORTING
             EVENT_ID             = EVENTID
         TABLES
              EVENT_CONTAINER      = EVENT_CONTAINER
         EXCEPTIONS
              OBJTYPE_NOT_FOUND    = 1
              OTHERS               = 2.
    COMMIT WORK.
Good Luck.

Passing object with NIO

HI All
I am trying to figure out if we can pass objects when using NIO.
If anyone has any idea about this please let me know
Thanks and Regards
Pankaj Tiwari

Very tricky. If you are in non-blocking mode you will have to prepend a length word. Generally the idea is to serialize the object to a ByteArrayOutputStream, then write its length and its data to the channel. At the other end, read the length word, then read that many bytes into a byte array, wrap that in a ByteArrayInputStream, then deserialize from that.
