Using Ref cursor from Procedure output in BPEL

Hi
Can any body help me ..
The output variable of db adapter is refcursor from stored procedure. in ref cursor i will get xml from a clob variable. how to use it in bpel...can an body help me how to do it....

APEX is based on Oracle Database. Whatever you can do with PL/SQL, the same can be done with APEX also. APEX stores the application definition in the form of metadata.
So if you put all your logic and code in packages, procedures or functions then it will be really good compact and modular approach.
Bottom line is that you can do all of those.
Check the documentation at
http://www.oracle.com/technetwork/developer-tools/apex/documentation/index.html

Using REF CURSOR from JDBC?

How do I use a REF CURSOR OUT parameter present in a Stored Procedure from my JDBC program?

here is an example, calling a packaged function. 1st param is delared as IN OUT REF CURSOR.

cs.registerOutParameter (1, OracleTypes.INTEGER);
cs.registerOutParameter (2, OracleTypes.CURSOR);
cs.setInt(3,mInt.intValue());
boolean boolValue = cs.execute();

Using Ref Cursor in procedure in place of normal cursor

Hi,
I have a procedure where i have the follwoing cursors declared,
CURSOR c_wip IS
SELECT tdvalue
FROM tabledetails
WHERE tdidcode = 'PEL_DASHBOARD'
AND tdkey LIKE 'WIP_QUEUES%';
CURSOR c_pending IS
SELECT tdvalue
FROM tabledetails
WHERE tdidcode = 'PEL_DASHBOARD'
AND tdkey LIKE 'PENDING_QUEUES%';
CURSOR c_out IS
SELECT tdvalue
FROM tabledetails
WHERE tdidcode = 'PEL_DASHBOARD'
AND tdkey LIKE 'OUT_QUEUES%';
CURSOR c_out_status IS
SELECT tdvalue
FROM tabledetails
WHERE tdidcode = 'PEL_DASHBOARD'
AND tdkey LIKE 'OUT_STATUS%';
Will the usage of 1 ref cursor instead of the 4 cursors increase the performance.
Thanks.

Cursor is a structure which points to a memory locations.
While a Ref-cursor is a datastructure which point to a object which inturn points to Memory locations.
The advantage of having Ref-cursor is that we can pass dynamically the Ref-cursor as a parameter to a procedures.
So it does improve the performance to a small extent.

Using Ref cursor in Procedure.

Hi All,
Can i use a single ref cursor multple times within the life cycle of a procedure.
Thanks,
Dillip

Yes.
See the example here. A cursor expression is selected - repeatedly, within a loop - into emp_cur (which is of type REF CURSOR) - and emp_cur is then used to process it in a nested loop.
(By the way - this question would be better asked in the PL/SQL).

Problem in using ref cursor

I have a procedure which is using one ref cursor as OUT paramater. Now when I call this procedure, it gives me the following error:
ORA-00932: inconsistent datatypes: expected CURSER got NUMBER
ORA-06512: at "APPS.ORDER_RETURN1", line 8
ORA-06512: at "APPS.ORDER_RETURN2", line 4
ORA-06512: at line 1
Below is my code
PROCEDURE ORDER_RETURN1(p_order OUT sys_refcursor) IS
TYPE OE_ORDER_rcur IS REF CURSOR;
rcur OE_ORDER_rcur;
BEGIN
OPEN rcur FOR
SELECT ORDER_NUMBER FROM OE_ORDER_HEADERS_ALL WHERE ROWNUM < 4;
FETCH rcur INTO p_order;
CLOSE rcur;
END ORDER_RETURN1;
PROCEDURE ORDER_RETURN2 IS
OE_ORDER_rcur11 sys_refcursor;
BEGIN
ORDER_RETURN1(OE_ORDER_rcur11);
end;
I tried to call proc ORDER_RETURN1 with the help of proc ORDER_RETURN2, but no change, it gives me same error if i call the first proc ORDER_RETURN1 or i call ORDER_RETURN2.
I am stuck with this problem, I had used ref cursor in procedure but not able to call the procedure which uses ref cursor as OUT parameter.
Please help me to resolve this.
Thanks

Using Ref cursor in Bpel

Hi,
I need to use ref cursors in bpel.
Basically calling a stored proc using DB Adapter , which returns a Ref cursor.
Not able to get it work, any suggestion help is greatly appreciated.
Also followed: http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28994/adptr_db.htm#CHDDDDJI
But its quite abstract.
Thanks !!

Hi Raj,
I am able to use the REF cursor with BPEL.
I am able to pass the resultset from Database using a REF cursor to a BPEL variable .
When you create a BPEL variable , create it with message type as the output message type of the REF Cursor.

How to get an UPDATABLE REF CURSOR from the STORED PROCEDURE

using C# with
ORACLE OLE DB version: 9.0.0.1
ADO version: 2.7
I returns a REF CURSOR from a stored procedure seems like:
type TCursor is ref cursor;
procedure test_out_cursor(p_Dummy in varchar, p_Cur out TCursor) is
begin
open p_Cur for select * from DUAL;
end;
I create an ADO Command object and set
cmd.Properties["IRowsetChange"].Value = true;
cmd.Properties["Updatability"].Value = 7;
cmd.Properties["PLSQLRSet"].Value = 1;
cmd.CommandText = "{CALL OXSYS.TEST.TEST_OUT_CURSOR(?)}";
and I use a Recordset object to open it:
rs.Open(cmd, Missing.Value,
ADODB.CursorTypeEnum.adOpenStatic,
ADODB.LockTypeEnum.adLockBatchOptimistic,
(int) ADODB.CommandTypeEnum.adCmdText +
(int) ADODB.ExecuteOptionEnum.adOptionUnspecified);
The rs can be opened but can NOT be updated!
I saved the recordset into a XML file and there's no
rs:baseschema/rs:basetable/rs:basecolumn
attributes for "s:AttributeType" element.
Any one have idea about this?
thanks very much

It is not possible through ADO/OLEDB.
Try ODP.NET currently in Beta, it is possible to update DataSet created with refcursors. You need to specify your custom SQL or SP to send update/insert/delete.
As I remember there is a sample with ODP.NET Beta 1 just doing this.

Procedure to fetch table records using ref cursor

Hi
i need to fetch all the records in the table using ref cursor.we need to pass table
name and the out paramater should be ref cursor.
CREATE OR REPLACE PROCEDURE gettable(p_table_name IN VARCHAR2,
p_ref_cursor OUT dept_pack.ref_cursor1)
IS
BEGIN
OPEN p_ref_cursor FOR SELECT * FROM p_table_name;
END gettable;
is that a start ? then after this i have to execute this procedure to fetch the data from table. i am getting error that table doesnot exist but my idea was to pass p_table_name as IN parameter.

STORED PROCEDURE/REF CURSOR: How to output entire buffer

I wrote a Stored Procedure wherein I use a Cursor to extract multiple
rows and columns. I then write them into the buffer
(dmbs_output.put_line). But when I try to capture the entire result
into an OUT variable, I only get the last buffered line.
So how do I output the entire buffer- all rows and columns? In other words (maybe), how do I use dbms_output.get_lines() to assign value to an OUT variable?
Alternatively, using REF CURSOR as OUT variable, I added the following to "CREATE OR REPLACE PROCEDURE ... ()":
cursor_out_test OUT cursor_test
But when I tried:
DEFINE CURSOR TYPE cursor_test IS REF CURSOR RETURN table%ROWTYPE;
...or...
DECLARE TYPE cursor_test IS REF CURSOR RETURN table%ROWTYPE;
I still got syntax errors.
In one line, what I am trying to do is break the result array at the database level rather than at the application level.
Cheers, Bill
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/sqloperations.htm#LNPLS00605

I did the following:
OPEN CURSOR x
     LOOP
          FETCH CURSOR x INTO col1, col2
          (EXIT WHEN...)
          variable_line := col1 || col2
     END LOOP
CLOSE CURSOR
But after closing this cursor, variable_line contains only the last buffered line. I want all the looped lines (without using associative arrays, nested tables etc). So I guess I am just looking for some way to append data lines- adding chr(10) doesn't work either.
Cheers, Bill

Reports 3.0, Ref Cursor from stored procedure

I have a problem trying to use Ref Cursor as datasource (i.e.
Ref Cursor Query) in Reports 3.0
I have created a stored package with a function which returns
Ref Cursor.
That function just opens the cursor and returns it to the
calling module.
Reports recognizes returned cursor - it creates a group for that
query, with all columns, than I built
a layout model - everything is OK on that stage.
During the execution of that report (from previewer or using
Reports Runtime) I got an error message like that:
REP-0065 Virtual Memory System Error
REP-0200 Cannot allocate enough memory cavaa22
Error's description does not correspond the reality :) - there
is enough virtual & physical memory according to
Task Manager information.
So, that does not work when this package is stored one.
When I create the package on the client side - in Reports -
everything works just fine.
Cursor is opened with a very simple query, selecting records
from the very simple table having only one record.
There is no code written which closes that cursor or fetches the
records.
Client platform: WinNT 4.0 SP3
Oracle Reports: 3.0.5.8.0
Oracle Server: Oracle8 8.0.5.0.0 (and I tried also on Oracle7
7.3.4.3.0)
Thanx.

Sara,
GTT (Global Temporary Tables) in Oracle work a different way compared to SQL Server and Informix. There you can create temporary tables on the fly and drop them on the fly.
Here you should (note, you don't have to, but, best practice says that you should) create the table using the syntax...
create global temporary table.....
Once you create it, even though it looks like persistent table, it's not. It will have it's own individual data PER SESSION . You have two types of GTTs:
ON COMMIT PRESERVE ROWS and ON COMMIT DELETE ROWS (they work in slightly different way).
Look up GTTs here:

Call procedure that uses REF CURSOR?

Can someone tell me how to call a procedure that uses a REF CURSOR?
Procedure is something like this:
PROCEDURE my_proc
P_PROG_ID IN VARCHAR2,
P_CRITERIA IN VARCHAR2,
P_TASKCURSOR OUT MYREFCUR
IS
blah, blah blah
I tried this to call the procedure:
exec my_proc(variable1,variable2,variable3)
but I don't know how to define variable3.
Can someone help me out?

Based on the parameters for the procedure, it looks like you have a cursor (myrefcursor) defined in a package somewhere. So, in sqlplus, you would need to do it in an anonymous block, something like:
DECLARE
   l_cur package_name,myrefcur;
   variables to hold cursor fields
BEGIN
   my_proc('ID', 'Criteria', l_cur);
   LOOP
      FETCH l_cur INTO variables to hold cursor fields
      EXIT WHEN l_cur%NOTFOUND;
      Do something with variables
   END LOOP;
   CLOSE l_cur;
END;If you are on Oracle 9 or higher, assuming that myrefcursor is weakly typed,
you could change the definition of the procedure to:
PROCEDURE my_proc (p_prog_id    IN VARCHAR2,
                   p_criteria   IN VARCHAR2,
                   P_TASKCURSOR OUT SYS_REFCURSOR)then you could call it in sql plus like:
-- Define the variables
var var1 VARCHAR2(100);
var var2 VARCHAR2(100);
var cur SYS_REFCURSOR;
-- Assign Vlaues to the IN parameters
EXEC :var1 := 'ID'; :var2 := 'Criteria';
EXEC my_proc(:var1, :var2, :cur);
-- See the contents of the cursor
print curHTH

Problem using REF CURSOR in JDBC

i have several stored procedures and functions that return REF CURSOR object as output. however, i'm noticing that if
no rows are returned within the cursor, the JDBC driver is throwing a "No more data to read from socket" exception.
i'm using the Oracle Thin JDBC driver v8.1.6 for JDK 1.2.
any help is appreciated.
