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!

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,
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..:-)

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:

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.

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?

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.

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?

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.

import java.io.Serializable;
import java.sql.Array;
import java.util.List;

import javax.persistence.Id;

     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),

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,

Calling a procedure that returns a cursor inside a procedure

Hi,
I have two stored procedures. They both return a cursor as output variables. On the other hand I have another stored procedure that calls these procedures and return their results again an output variable. I know that this seems quite odd to be wanting to do something like this but how can I do that?

You can make the hack generic. Make it execute any SQL as that schema that creates the ref cursor. E.g.
// as schema BILLY, open a huge security hole and grant access to USER1
SQL> create or replace procedure GetTableData( tableName varchar2, refCur out sys_refcursor ) authid definer is
2          dynamicSQL      varchar2(32767);
3 begin
4          dynamicSQL := 'select * from '||tableName;
5          open refCur for dynamicSQL;
6 end;
7 /
Procedure created.
SQL>
SQL>
SQL> grant execute on GetTableData to USER1;
Grant succeeded.As USER1, you can now execute SQL (and even PL/SQL) as BILLY:
SQL> create or replace type TStrings is table of varchar2(4000);
2 /
Type created.
SQL> grant execute on TStrings to BILLY;
Grant succeeded.

Error executing Stored Procedure that returns a recordset in Visual Basic 6

Hello, i tried to use the example in the link posted as a response to my question in a previous thread, and in Visual Basic 6, when i execute the Stored procedure it gives me the following error:
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.

Testing procedure that returns cursor.

Please
How Can I test a procedure that returns a cursor? I need to execute it on sqlplus.
Thank you very much

Hi,
Example using HR schema:
The proc_cursor procedure returns a cursor and the block below test it
SET SERVEROUTPUT ON
DECLARE
    TYPE t_ref_cur IS REF CURSOR;
    v_cursor   t_ref_cur;
    v_employee employees%ROWTYPE;
    PROCEDURE proc_cursor(p_cursor OUT t_ref_cur) IS
        v_sql VARCHAR2(4000);
    BEGIN
        v_sql := 'SELECT * FROM EMPLOYEES';
        OPEN p_cursor FOR v_sql;
    END;
BEGIN
    proc_cursor(p_cursor => v_cursor);
    LOOP
        FETCH v_cursor
            INTO v_employee;
        EXIT WHEN v_cursor%NOTFOUND;
        dbms_output.put_line(v_employee.employee_id);
    END LOOP;
    CLOSE v_cursor;
END;
/Regards,

Stored Procedure/Function Returns Rows?

Hello,
I have very little experience writing PL/SQL procedures, but I have written my fair share of Sybase stored procedures. In Sybase, I can create a stored procedure that returns rows of data. For example:
create procedure myproc as
begin
select * from mytable;
end;
Then if I invoke the procedure (whether that is from an interactive SQL session or from a ColdFusion or JSP page), several rows of data are returned to me.
The benefit of this is that the web developers don't need to write complicated SQL.
Is this even possible in Oracle? I have never seen anyone actually do this. Or do my web coders need to learn how to write PL/SQL and embed it into their code?
HELP!
Thanks!

Hi Justin,
Thanks for your reply. That's kind of what I was suspecting, except that I was hoping to be able to execute the function/procedure from within a SQL session also, for testing. Is there a way to invoke such a procedure from a SQL*Plus session and have it return the rowset (ref cursor) just as if I had typed in the SQL select statement?
For example, I just want to type at a SQL*Plus prompt something like this:
mypackage.myfunction(param1, param2);
and then have it return the results to me. Is that possible?
Thanks again for your help.
Mark
