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.
JPA Class:
import java.io.Serializable;
import java.sql.Array;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.Id;
import org.eclipse.persistence.annotations.Direction;
import org.eclipse.persistence.annotations.NamedStoredProcedureQuery;
import org.eclipse.persistence.annotations.StoredProcedureParameter;
* The persistent class for the MessagePublish database table.
@Entity
@NamedStoredProcedureQuery(name="GetTeamMembersDetails",
     procedureName="team_emp_maintenance_pkg.get_user_team_roles",
     resultClass=TeamMembersDetails.class,
     returnsResultSet=true,
     parameters={
     @StoredProcedureParameter(queryParameter="userId",name="I_USER_ID",direction=Direction.IN,type=Long.class),
     @StoredProcedureParameter(queryParameter="employeeId",name="I_EMPLOYEEID",direction=Direction.IN,type=Long.class),
     @StoredProcedureParameter(queryParameter="TEAMMEMBERSDETAILSOT",name="O_TEAM_ROLES",direction=Direction.OUT,jdbcTypeName="OBJ_TEAM_ROLES"),
     @StoredProcedureParameter(queryParameter="debugMode",name="I_DEBUGMODE",direction=Direction.IN,type=Long.class)
public class TeamMembersDetails implements Serializable {
     private static final long serialVersionUID = 1L;
@Id
     private long userId;
     private List<TeamMembersDetailsOT> teamMembersDetailsOT;
     public void setTeamMembersDetailsOT(List<TeamMembersDetailsOT> teamMembersDetailsOT) {
          this.teamMembersDetailsOT = teamMembersDetailsOT;
     public List<TeamMembersDetailsOT> getTeamMembersDetailsOT() {
          return teamMembersDetailsOT;
Procedure
PROCEDURE get_user_team_roles (
i_user_id IN ue_user.user_id%TYPE
, o_team_roles OUT OBJ_TEAM_ROLES_ARRAY
, i_debugmode IN NUMBER :=0)
AS
OBJ_TEAM_ROLES_ARRAY contains create or replace TYPE OBJ_TEAM_ROLES_ARRAY AS TABLE OF OBJ_TEAM_ROLES;
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,

Help! Need oracle help with constructing stored procedure that return resultsets

Suns tutorial path for returning resultsets from stored procedures indicates that the following should work...
CallableStatement cs = con.prepareCall("{call SHOW_SUPPLIERS}");
ResultSet rs = cs.executeQuery();
Thats if you build your stored procedure something like this ...
String createProcedure = "create procedure SHOW_SUPPLIERS " + "as " + "select SUPPLIERS.SUP_NAME, COFFEES.COF_NAME " + "from SUPPLIERS, COFFEES " + "where SUPPLIERS.SUP_ID = COFFEES.SUP_ID " + "order by SUP_NAME";
We are using oracle 8.1.6. However I've been told that with oracle procedures when you return a result set from a called procedure you return a p_cursor variable. Somthing like this
(p_cursor in out SHOW_SUPPLIERS.SHOCurTyp)
is
begin
open p_cursor for
select * from suppliers
In which case the above mentioned sun code doesn't work.
We want to use jdbc to call a stored procedure that returns a resultset that does not require us to import any proprietary oracle objects...
Is there another way to write these stored procedures, rather than using this cursor construct? Are we missing something in the way we invoke them?

Using XI - RFC table and an Oracle stored procedure that returns a cursor.

I need to create an interface using XI between an RFC table and an Oracle stored procedure that returns a cursor. We are on oarcle 9.2 and SP12.
My stored procedure looks something like this:
CREATE OR REPLACE
PROCEDURE testproc_xi2 (p_recordset1 OUT SYS_REFCURSOR,
                                         in_quoteid IN varchar2 )
AS
BEGIN
OPEN p_recordset1 FOR
   SELECT q.quote_id,
                 q.modified_by,
                 q.quote_status,
                 q.total_cost
            FROM quote q
           WHERE q.quote_id = in_quoteid
             AND q.total_cost > 0 ;
END testproc_xi2 ;
My RFC has table and one import parameter .
I wanted to know how to create the data type for the ref cursor? and also for the table type in the RFC?
CAN XI handle multi rows coming from a Stored procedure? Are there any other alternative methods if this is not supported?Any pointers to this would be helpful.
I have called a Oracle SP from an RFC before, but that interface had one input parameter going to the stored procedure from the RFC and about 6 o/p parameters coming from the Stored procedure. This works fine.
Thanks for the help.
Mala

Mala,
i dont think there is anything called an rfc table...RFC stands for remote function call. That in essence would imply you need a rfc to jdbc connection.
yes XI can handle multiple rows cooming from the the stored procedure if you have them mapped appropriately.
Now as to how to create the data type within xi , you need to know what fields are going to be returned and whether they are nested and then just create them as you would for an xml
for ex
<Details>
<FirstName>
<LastName>
</Details>
that in xi would be smthing like
Details type of data occurence
FirstName type of data occurence
LastName type of data occurence.
Hope that helps.
If it does dont forget the points..:-)

Stored procedure that returns multiple tables

Hello everyone,
I was wondering if there's a way to write a stored procedure that returns multiple result set as in sql server. for example, in sql server, you can write 2 select statements and when loading them in c#, u can get two data tables.
I am not sure having a single ref cursor for each select is the only solution. I might need to return a variable number of tables per procedure call (based on a certain criteria).
Any ideas?
thanks for your time

Sure. Ref cursor is the only easier answer for your problem.

Stored procedure that returns a cursor (result set)

Hi,
We have a stored procedure that returns a cursor (result set) but when I compliled it and catalouged (introspected) it in the OBPM I got all the primitive type parameters (either IN or OUT) in the proc call except the cursor type (the result set) which is the out param of the stored proc.
Any pointers please?
Thanks

Result set is of RowType and is not supported as a Stored Procedure as far as I know.

Function calling stored procedure that returns a cursor into a LOV

Hello,
Is it possible in HTML DB to implement a process that has a function that calls a stored procedure that returns a cursor, used to then populate a select list?
Or can I do a function call to a stored procedure in the 'List of values definition' box for the item itself that returns a cursor to populate the item's select list?

Hi Vikas,
Actually, I just found another posting that shows how to do what I'm looking for:
Re: Filling a LOV with a cursor
Check it out. I posted another question in response to that discussion...maybe you could answer that? Thanks!

Call a Stored Procedure that returns a REFCURSOR using ODI Procedure

Hi,
I have a scenario wherein the stored procedure (TEST_PROC1) that returns a REFCURSOR. The second procedure(TEST_PROC2) will use the REFCURSOR as inpuut and insert it to a table.
Now, I need to execute the test procedures (TEST_PROC1 and TEST_PROC2) using the ODI Procedure but I always get error. However, I was able to execute the test procedures using sqlplus. Here is the command I used for sqlplus:
               var rc refcursor
               exec TEST_PROC1(:rc);
               exec TEST_PROC2(:rc);
PL/SQL Stored Procedure:
-- TEST_PROC1 --
create or replace
PROCEDURE TEST_PROC1 (p_cursor IN OUT SYS_REFCURSOR)
AS
BEGIN
OPEN p_cursor FOR
SELECT *
FROM test_table1;
END;
-- TEST_PROC2 --
create or replace
procedure TEST_PROC2( rc in out sys_refcursor ) is
FETCH_LIMIT constant integer := 100;
type TFetchBuffer is table of test_table2%RowType;
buffer TFetchBuffer;
begin
loop
fetch rc bulk collect into buffer limit FETCH_LIMIT;
forall i in 1..buffer.Count
insert into test_table2(
c1, c2
) values(
buffer(i).c1, buffer(i).c2
exit when rc%NotFound;
end loop;
end;
Is there a way to call a PL/SQL Stored Procedure that returns a REFCURSOR using ODI Procedure?
Thanks,
Cathy

Thanks for the reply actdi.
The procedure TEST_PROC1 is just a sample procedure. The requirement is that I need to call a stored procedure that returns a cursor using ODI and fetch the data and insert into a table, which in this case is test_table2.
I was able to execute a simple SQL procedure (without cursor) using ODI procedure. But when i try to execute the SQL procedure with cursor in ODI, I encountered error.
Do you have any idea how to do this?

Call to Oracle stored procedure that returns ref cursor doesn't work

I'm trying to use an OData service operation with Entity Framework to call an Oracle stored procedure that takes an number as an input parameter and returns a ref cursor. The client is javascript so I'm using the rest console to test my endpoints. I have been able to successful call a regular Oracle stored procedure that takes a number parameter but doesn't return anything so I think I have the different component interactions correct. When I try calling the proc that has an ref cursor for the output I get the following an error "Invalid number or type of parameters". Here are my specifics:

I also don't know if I'm invoking the stored procedure correctly in my service operation? I'm testing everything through the rest console because the client consuming this information is written in javascript and expecting a json format. Any help is appreciated!

Making the change you suggested still resulted in the same Oracle.DataAccess.Client.OracleException {"ORA-06550: line 1, column 8:\nPLS-00306: wrong number or types of arguments in call to 'GETWORKORDERSBYWINDFARMID'\nORA-06550: line 1, column 8:\nPL/SQL: Statement ignored"} System.Exception {Oracle.DataAccess.Client.OracleException}
I keep thinking it has to do with my oracle.dataaccess.client settings in App.Config because I don't actually put the WindfarmId and an input parameter. I tried a few different ways to do this but can't find the correct format.

How to call a stored procedure that has Table Of data types in VB6?

Hi everyone,
I need to call a stored procedure that has a Table Of data type as an input parameter (possibly even several Table Of input parameters). I can't seem to find any example of how to do this in VB6 using ODBC. Is this even possible?
Thanks you!
Steve

Thanks,
but I need to test stored procedures that uses type defined in the package.
e.g.
if I have s.p.
PROCEDURE get_risultati_squadra
( in_squadra IN VARCHAR2,
out_serie OUT tab_varchar2_5,
out_tiporisultato OUT tab_varchar2_5,
out_n_giornata OUT tab_varchar2_5,
out_squadre OUT tab_varchar2_200,
out_risultato OUT tab_varchar2_10,
out_marcatore OUT tab_varchar2_50,
out_punti OUT tab_varchar2_3,
out_rimbalzista OUT tab_varchar2_50,
out_rimbalzi OUT tab_varchar2_3,
out_esito OUT tab_varchar2_2);
I have to define every type external to the package, in this case five new TYPE !!
Is there another way to solve this problem?
Thanks

This is the package created as indicated in the example FAQ you posted.
package types
as
type cursorType is ref cursor;
end;
This is the procedure created as indicated in the example FAQ you posted.
PROCEDURE SP_TITUVALO(T_BR IN VARCHAR2,
P_Cursor OUT TYPES.cursorType )
AS
BEGIN
OPEN P_Cursor FOR
SELECT * FROM TASAS WHERE BR=T_BR AND TASA > 0;
END;
This is the code used to execute the Stored Procedure in VB6:
Dim objConn As New ADODB.Connection
Dim connString
Dim cmdStoredProc As New ADODB.Command
Dim param1 As New ADODB.Parameter
Dim RS As ADODB.Recordset
Set param1 = cmdStoredProc.CreateParameter("T_BR", adVarChar, adParamInput, 255, "97")
cmdStoredProc.Parameters.Append param1
objConn.Open strconex
Set cmdStoredProc.ActiveConnection = objConn
cmdStoredProc.CommandText = "SP_TITUVALO"
cmdStoredProc.CommandType = adCmdStoredProc
Set RS = cmdStoredProc.Execute
This is the error returned:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'SP_TITUVALO'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
****************************************************************

Juan,
Not sure about FAQ you are referring to, but it seems that you need to set PLSQLRSet property of ADODB.Command to TRUE. Because if you fail to do so - errors with refcursors are likely to happen.
Consider:
Set objConn = CreateObject("ADODB.Connection")
objConn.ConnectionString = "Provider=OraOLEDB.Oracle;Persist Security Info=False;Data Source=test9ora;User ID=max;Password=blabla"
objConn.Open
'Dim cmdStoredProc
Set cmdStoredProc = CreateObject("ADODB.Command")
Dim param1
Set param1 = cmdStoredProc.CreateParameter("T_BR", adVarChar, adParamInput, 255, "97")
param1.Value = "X"
cmdStoredProc.Parameters.Append param1
'Dim RS
Set cmdStoredProc.ActiveConnection = objConn
'The following line was missed out
cmdStoredProc.Properties("PLSQLRSet") = True
cmdStoredProc.CommandText = "SP_TITUVALO"
cmdStoredProc.CommandType = adCmdStoredProc
Set RS = cmdStoredProc.ExecuteThis works fine, at least for me.
Cheers.

Stored Procedure: Function returns Array

I was just wondering if following scenario is possible in a stored procedure.
I have a package, which includes 4 different functions and 1 procedure. Procdure uses ref cursor to return values in my reporting tool. What I am trying to do is to write a function which takes input and return array of varchar. Something like..
Package ABC
Function student_classes (student_no in Varchar2) return [array]
begin
select class_nbr into [array]
from student_table
where student_nbr = student_no;
return [array];
end student_classes;
procedure students_info (rpt_cursor IN OUT rpt_type)
begin
OPEN rpt_cursor FOR
select
student_name,
student_nbr,
student_address,
student_classes (student_nbr) --returns array
from student_table;
end student_info; --end of procedure
end abc; --end of pacakge.
I used [array], as I am ont sure how to define (syntax) it in spec part of package or in body. I will really appreciate if someone could help me with this function.
Thank you

Thanks for the reply Tonguc Y.
I declared an array in my package declaration
CREATE OR REPLACE PACKAGE rpt_TESTING_pkg
AS TYPE rpt_type IS REF CURSOR;
     TYPE DIAGARRAY IS VARRAY(20) OF VARCHAR2(6);
     FUNCTION DIA_CODES (MNO IN VARCHAR2) RETURN DIAGARRAY;
     PROCEDURE member (rpt_cursor IN OUT rpt_type);
END rpt_TESTING_pkg;
but then when I try to use it in my function it gives me error that I should declare DIAGARRAY.
CREATE OR REPLACE PACKAGE BODY rpt_TESTING_pkg
as
FUNCTION DIA_CODES (MNO IN VARCHAR2)
               RETURN DIGARRAY AS diags DIGARRAY;
begin
<sql block>
end dia_codes;
end rpt_TESTING_pkg;
Any suggestions.

Debugging Oracle Object types

Hi
I'm trying to debug a application (in 9i Release 2) using PL/SQL object types and was wondering if JDev can help.
I can see the objects, and their code, but the debugger seems unable to step into them, see local variables etc. It also incorrectly identifies code errors -- in short it appears to be using the 9i Release 1 drivers.
I've just installed version 9.0.3.2 but that hasn't helped. The release notes say helpfully that 9.0.3 can handle the drivers for 9i R2, but it won't use them!
I'm about to try the 10g preview, but I'm not feeling hopeful. Is this something I can expect to be fixed or do I have to find some other way of debugging my code?
Thanks,
Glenn.

Hi,
I also have problems debugging oracle objects. I'm running an Oracle Database Version 9.2.0.1.0 and use
JDeveloper 9.0.3 to remotely debug PL/SQL Code. The debugging works fine when I'm setting breakpoints and
step through the code.
But I seem to be unable to list the value of variables of
object types and variables of nested table types. And of course I cannot set conditional breakpoints on variables that have an Oracle object type. If I try 10g, there is no improvement. The object types are not recognized as Oracle object types or nested table types, instead they are shown as $Oracle.builtin.OPAQUE
I need this feature to remotely debug procedures, that mostly use Oracle object types as parameters. Is there any possibility that I can get this feature to work? Otherwise JDeveloper is not much of a use for me when I'm debugging PL/SQL code.
Thanks,
Astrid
I provided an example, in which I create the above mentioned types and fill them with data, but where I'm unable to retrieve the values of the variables in JDeveloper:
---------------------EXAMPLE--------------------------
PROMPT Creating TYPE 'ot_hwemployee'
CREATE OR REPLACE TYPE ot_hwemployee AS OBJECT (
emp_id NUMBER (10),
emp_name VARCHAR2 (200)
PROMPT Creating TYPE 'nt_hwemployee'
CREATE OR REPLACE TYPE nt_hwemployee AS TABLE OF ot_hwemployee
PROMPT Creating TYPE 'nt_hwinteger'
CREATE OR REPLACE TYPE nt_hwinteger AS TABLE OF NUMBER (20)
PROMPT Creating PROCEDURE 'checkEmployees'
CREATE OR REPLACE PROCEDURE checkEmployees
AS
vnt_employees nt_hwemployee;
BEGIN
vnt_employees := nt_hwemployee(ot_hwemployee(1, 'Mustermann Max'),
ot_hwemployee(2, 'Beispiel Barbara'),
ot_hwemployee(3, 'Schober-Gant Astrid'));
deleteemployees(vnt_employees);
END checkEmployees;
PROMPT Creating PROCEDURE 'deleteEmployees'
CREATE OR REPLACE PROCEDURE deleteEmployees (
pnt_employees IN OUT nt_hwemployee)
AS
vnt_employees_deleted nt_hwinteger;
BEGIN
vnt_employees_deleted := nt_hwinteger();
FOR i IN pnt_employees.FIRST .. pnt_employees.LAST LOOP
IF (pnt_employees(i).emp_id > 2) THEN
vnt_employees_deleted.EXTEND;
vnt_employees_deleted(vnt_employees_deleted.COUNT) := pnt_employees(i).emp_id;
pnt_employees.delete(i);
END IF;
END LOOP;
END deleteEmployees;

Calling a Procedure which has Array of Objects as arguments (from BPEL)

Hi,
I wanted to pass multiple records as arguments to a stored procedure from BPEL.
We created stored procedure which takes array of Objects as arguments. I invoked it from BPEL. It was successfully compiled and deployed.
At runtime it is throwing following error.
<bindingFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="code">
<code>17072</code>

<part name="summary">
<summary>Error binding the value of a parameter. An error occurred when binding the value of parameter ARG in the SCOTT.TESTPACK.TESTPROC API. Cause: java.sql.SQLException: Inserted value too large for column: "sadfsafsad" Check to ensure that the parameter is a valid IN or IN/OUT parameter of the API. Contact oracle support if error is not fixable.</summary>

I think you from Sierra Atlantic and you using Beta 3. There was a bug in Beta 3 in using arrays, which got fixed in post Beta3. You got to wait till next release.
