OUT PARAMETER SYS_REFCURSOR ?

hI , i HAVE THE FO9LLOWING CODE..wHICH CALLS A PROCEDURE WHICH HAS OUT PARAMETER AS SYS_REFCURSOR. out_par.
pm_saveproduct.pm_saveproduct('etl',v_product_data_type,out_par);The called procedure populates the out_par as follows.
OPEN out_status FOR
                  SELECT lv_prod_id, 'S',
                         'Successfully updated product data'
                    FROM DUAL;Now how can i read these values in my main proc?

-- This gives Nuric or value error.
check
lv_prod_id INTEGER;
while in fetch statement if some parameter is fetching -ve value then
this error occurs.

Performance issue with using out parameter sys_refcursor

Hello,
I'm using Oracle 10g, with ODP.Net in a C# application.
I'm using about 10 stored procedures, each having one out parameter of sys_refcursor type. when I use one function in C# and call these 10 sp's, it takes about 78ms to excute the function.
Now to improve the performance, I created one SP with 10 output parameters of sys_refcursor type. and i just call this one sp. the time taken has increased , not it takes abt 95ms.
is this the right approach or how can we improve the performance by using sys_refcursor.
please suggest, it is urgent, i'm stuck up with this issue.
thanks
shruti

With 78ms and 95ms are you talking about milliseconds or minutes? If it's milliseconds then what's the problem and does it really matter if there is a difference of 17 milliseconds as that could just be caused by network traffic or something. If you're talking minutes, then we would need more information about what you are attempting to do, what tables and processing is going on, what indexes you have etc.

OUT parameter with NOCOPY hint of type SYS_REFCURSOR

Hi,
I am having a procedure which returns a set of 100+ records (each record having 10+ columns) through a OUT parameter of type SYS_REFCURSOR.
These output records are used in JAVA code for fecthing the resultset and process data.
Will it make any difference in performance if I use NOPCOPY compiler hint in this procedure (especially I am interested in the interaction between JAVA and PLSQL, with and without NOCOPY parameter).
Thanks.

Hi RP,
Thanks for the answer.
So the PLSQL OUT parameter of type SYS_REFCURSOR would be passing just a reference (memory address) to JAVA.
This behavior is same with or without NOCOPY. Is my understanding correct?
Thanks.Yes. A ref cursor is just a pointer to a query, not a result set of data. Using NOCOPY or not is pointless (excuse the pun) because, no matter how much data is going to get returned, the pointer itself is no smaller or larger in size, and thus using NOCOPY won't improve performance or save resources.

Oracle Instant Client and OUT Parameter of custom type in Stored Procedures

Hi @ all!
I try to set up a simple client application, that calls a stored procedure via Instant Client from C#.
The stored procedure and assiciated types looks like this:
TYPE MYVALUE AS OBJECT
      Id      INTEGER,
      value     FLOAT
TYPE MYVALUELIST AS TABLE OF MYVALUE;
PROCEDURE ReadValues( ID IN INTEGER,
                                    RESULTSET OUT MYVALUELIST)
                                       IS
...I created an Oracle Command executing this SP and added OracleParameters for ID and (where I got stuck) the RESULTSET.
Is it possible to pass a parameter with a custom type from C# in some way?
I already tried it as a function with SELECT * FROM TABLE(ReadValues(1));
With my parameter RESULTSET as the RETURN type. But since I use DML within the procedure, this does not work inside of a query...
Any suggestions?
Thanks in advance!

Hi Greg!
Sorry, I misunderstood the forum topic then. =(
Anyway, in the example you provided in the link, this is nearly exactly my situation. But there the Oracle.DataAccess.Client is used, where the OracleDBType can be called to initialize an object of type person. I use the instant client libraries called by using System.Data.OracleClient. There is only the OracleType enum, that does not contain an object or something similar.
So I do it right now after trying a bit with a ref cursor parameter and an OracleDataAdapter - the ref cursor is passed back from Oracle as a DataReader, so die DataAdapter is able to use it for a .Fill():
OracleCommand cmd = new OracleCommand();
cmd.Parameters.Add("RESULTSET", OracleType.Cursor).Direction = ParameterDirection.Output;
OracleDataAdapter odr = new OracleDataAdapter(cmd);
DataTable result = new DataTable();
odr.Fill(result);Within my stored procedure I just added the following OUT parameter:
PROCEDURE ReadValues( ID IN INTEGER,
                                    RESULTSET OUT sys_refcursor)
                                       IS
currentlist MYVALUELIST;
... [Adding elements to that list] ...
OPEN resultset for select * from TABLE(currentlist);It works now, but I don't like that solution that much since I'm always afraid that there are lots of opened cursors idyling around. Do I have to close this one explicitly after filling my table by the DataAdapter?

Pass a record type vaiable in out parameter of a function in a package

Hi All,
1.I have created a ecod inside a package.
2.Then created a function which has a out parameter of the above record.
3.Now package body i'm creating a dynamic cursor .
4.My equirement is to fetch this dynamic cursor's value into the out parameter of the function.
I have created the below code for 1,2 and 3 but not getting how to achive the point 4.
create package pkg
type t_rec is recod (id number,id_name varchar2(10));
type t_data is table of t_rec index by binary_integer;
act_data t_data;
funcion return_data is (dept in number,region in number,o_rec out t_data) return boolean;
end pkg;
create package body pkg
funcion return_data is (dept in number,region in number,o_rec out t_data) return boolean is
p_cur sys_refcursor;
l_text varchar2(100);
begin
-- As per my requirement i have built a dynamic l_text which contains where clause by taking dept and region values.In actual i have nearly 10 in paramaters with >which i'm building a dynamic where clause in l_text. So i'm using a ref cursor.
open p_cur for 'select id,id_name from tab1'||l_text';
fetch p_cur bulk collect into act_data;
exception ....
end pkg;Now as per the code snippet i could fetch all the rows returned by p_cur into act_data.
But how i will pass it though out parameter in the function which i will use somewhere in front end to show data.
Please help me in this.
Thanks in advance.

i need to create the where clause one the basis of the values of IN parameters.Sometimes i need to take count of the data on the basis of the IN parameters and if one of the conditions return value i will build where clause with those parameters.Please google and read up on the importance of creating shareable SQL - which needs to be done using bind variables.
The ref cursor interface in PL/SQL only support a static/fixed number of bind variables. So if you want to create cursors with variable number of bind values, you need to use conditional processing. E.g.

SQL>And this approach is for external clients - where a Visual Basic or Java client program calls the database, executes the stored procedure, and receives a cursor handle in turn. And the client then fetches the output of this cursor and process it.
There is no need to return a record type of any sorts. The client wants the cursor handle as that is the optimal and best interface for the client to receive database data.
If the caller is not an external client, but another PL/SQL procedure, then this approach does not make much sense.
It is important that you understand basic Oracle concepts and fundamentals. What a cursor is. What the best way is to process Oracle data. How to best use the basic features of Oracle. Without that basic understanding, you as good as a low hour Cessna pilot getting into an Airbus A400M - where the Cessna pilot would not even be able to start a single engine, never mind get the plane in the air.
Likewise, without a basic understanding of Oracle cursors and fundamentals, you will be unable to code even a single line of sensible code. Not because you are a bad programmer. Even the best programmer in the world will be unable to write decent code, if the programmer has no idea how the environment works, what the concepts and fundamentals are. But it is fair to expect that a good programmer will no write such code, understand that there is a lack of knowledge, and address that accordingly.

Stored procedure with IN and OUT parameter

HI all,
here is code example
declare
         in_dt date := '1-feb-2010' ;
col1 ...;
col2 ...;
col3 ...;
begin
select e.*
into col1,
        col2,
        col3
from table_xyz e
where e.start_dt = in_dt;
end;
How do i convert the above code into stored procedure by accepting "in_dt" as IN parameter and getting the result set displayed (output) through OUT parameter say "cur_out" (OUT paramter)
Thank you so much !!! I really appriciate it !!

i ran my procedure which is very similar syndra posted
create or replace procedure foo(p_dt in date, cv out sys_refcursor) as
begin
open cv for
select e.*
from table_xyz e
where start_dt = p_dt;
end;
/Here is how is executed
DECLARE
P_DT DATE;
CV SYS_REFCURSOR;
BEGIN
P_DT := '10-oct-2005';
-- CV := NULL; Modify the code to initialize this parameter
scott.foo ( P_DT, CV );
COMMIT;
END;
-- i get PL/SQL procedure successfully complted , But i dont see the result set Or output
- How do i see the output when i m using refcursor ?? i tried using print , but nothing didnt work
- Any idea ??
Thank you!!

Return Cursor as OUT Parameter

I have one Implicit Cursor which will store the table Data.May I have any Chance to send Implicit Cursor as OUT parameter?.

1) cursors (implicit or explicit) do NOT STORE table data. tables store table data.
2) why does implicit vs explicit matter to you? just write the code in the way that works
3) to return a cursor, use a refcursor
create procedure y ( rc in out sys_refcursor ) as
begin
open rc for select * from dual;
end;
SQL> var rc refcursor
SQL> exec y ( :rc )
PL/SQL procedure successfully completed.

Is it possible to return a cursor as a HANA Stored Procedure OUT parameter?

Hi,
I have a use case where I need to return a record set from a HANA Stored Procedure to the caller based on a couple of input parameters to the procedure. However, the record set needs to be dynamic and may have different columns based on the input parameters.
I could achieve this by creating hdbstructures or using table types as OUT parameters. However, is it possible to return a cursor holding the result set of a SELECT query as an OUT parameter for a HANA stored procedure?
(I am looking for something similar to Oracle's SYS_REFCURSOR)
Best Regards,
Abhik

Did you try using EXECUTE IMMEDIATE

Error while calling a stored procedure with OUT parameter.

Hi,
I am trying to call a Stored Procedure(SP) with an OUT parameter(Ref Cursor) from a third party tool. It is called using OLE-DB Data provider. In one database the procedure works fine but when I change the database the procedure call is giving following error.
Distribution Object:     COM Error. COM Source: OraOLEDB. COM Error message: IDispatch error #3092. COM Description: ORA-06550: line 1, column 7:

I am not able to find as to why is this happening. Please let me know any clues /help to solve this problem.
Thanks in advance.

If you're using Oracle Provider for OLE DB (OraOLEDB) to execute this stored procedure, you need to set PLSQLRSet attribute. This attribute can be set in registry, connection string, or command object. Please refer to User Documentation for more information.

Cursor bound to out parameter with Connection Pool

Is it possible to retrieve a cursor bound to an out parameter when using the thin
driver to establish the connection pool to the database? I am currently using
the JDriver to connect create the pool and the pool driver to connect from the
app to the connection pool. We'd like to avoid using the Oracle client if possible.
Currently I register the out parameter as java.sql.Types.OTHER, then call getResultSet(1)
on the weblogic.jdbc.pool.CallableStatement object. But it breaks when I change
the connection pool to use the thin driver. The error is at the bottom of this
post.
I think I could possibly get the current pool driver to work if can find some
documentation on these two methods:
void registerOutParameter(int i, int j, int k, int l)
void registerOutParameter(int i, int sqlType, java.lang.String typeName)
I have no idea what to put in for the ints in the first method or for sqlType
or typeName. Can anyone point me to where I can find this documentation?
E-docs mentions this class: weblogic.jdbc.vendor.oracle.OracleCallableStatement.
(http://edocs.bea.com/wls/docs61/jdbc/thirdparty.html#1023867). Should I consider
this? If so where is it?

Thanks Joe, your answer pointed me in the right direction. Just in case anyone
wants to know, the solution took two changes:
CHANGE
cStat.registerOutParameter(1, java.sql.Types.OTHER);
TO
cStat.registerOutParameter(1, oracle.jdbc.driver.OracleTypes.CURSOR);
(cStat is an instance of weblogic.jdbc.pool.CallableStatement)
AND
rs = cStat.getResultSet(1);
TO
rs = cStat.getCursor(1);
Thanks again,

Hi Matt.
Look at the Oracle thin driver documentation to determine what type you
should define in the registerOutParameter call. We use 'OTHER', but
their driver may use something else for CURSOR output parameters.

Can we use OUT or IN OUT parameter mode in function?

Can we use OUT or IN OUT parameter mode in function & if YES then what's limitations?

hi,
Yes we can have OUT and IN OUT parameters for a function.
As per my knowledge there are no limitations , but as per the convention we will use OUT ,IN OUT Parameter modes for only procedures .
Thanks,

Cannot get OUT parameter from stored procedure

Hi,
I am new to stored procedure programming. I wrote a simple java stored procedure as follows:
package fvt;
import java.sql.*;
import java.io.*;
public class FVTProcedures
extends COM.ibm.db2.app.StoredProc {
public void addRecord(int id, String name, int status)
throws SQLException {
java.sql.Statement stmt = null;
java.sql.Connection con = null;
PrintWriter pw = null;
try {
status =3;
pw = new PrintWriter(new FileWriter("c:/temp/fvtproc.txt"));
pw.println("starting...");
// get connection
con =getConnection();
pw.println("Got connection");
stmt = con.createStatement();
stmt.execute("INSERT INTO cmtest (id, name) values (" + id + ",'"+name+"')");
pw.println("Inserted the record");
if (!con.getAutoCommit()) {
con.commit();
pw.println("Committed the connection");
catch (SQLException sqle) {
pw.println(sqle.getMessage());
catch (Exception e) {
pw.println(e.getMessage());
finally {
status =2;
pw.close();
try {
if (stmt != null) {
stmt.close();
catch (SQLException sqle) {}
try {
if (con != null) {
con.close();
catch (SQLException sqle) {}
Then I use the following sql command to create this stored procedure, especially register status as OUT parameter.
CREATE PROCEDURE addRecord (IN id INT, IN name VARCHAR(20), OUT status INTEGER)
FENCED LANGUAGE JAVA EXTERNAL NAME 'fvt.FVTProcedures!addRecord' PARAMETER
STYLE DB2GENERAL
My java program calling this stored proc is as follows:
import java.sql.*;
import javax.sql.*;
public class CallableStmtTest {
     COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource ds = null;
     public static void main(String args[]) {
          CallableStmtTest dt = new CallableStmtTest();
          try {
               dt.test();
          } catch (Exception e) {
               e.printStackTrace(System.out);
     public CallableStmtTest() {
          ds = new COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource();
          ds.setUser("username");
          ds.setPassword("password");
          ds.setDatabaseName("database");
public void test() {
java.sql.Connection conn = null;
CallableStatement cs = null;
String sql = "CALL ADDRECORD(?, ?, ?)" ;
try {
conn = ds.getPooledConnection().getConnection();
conn.setAutoCommit(false);
System.out.println("Got the connection");
cs = conn.prepareCall( sql ) ; /* con is the connection */
System.out.println("Callable statement is prepared");
cs.registerOutParameter(3, java.sql.Types.INTEGER);
cs.setInt(1, 1001 );
cs.setString(2, "1001");
cs.execute() ;
System.out.println("Callable statement is executed, return status: "+cs.getInt(3));
conn.commit();
catch(SQLException sqle) {
sqle.printStackTrace();
finally {
try {
if (cs!=null) {cs.close();}
catch (SQLException sqle1) {
try {
if (conn!=null) {conn.close();}
catch (SQLException sqle1) {
However, the out put is always
Callable statement is executed, return status: 0
while i expect to be
Callable statement is executed, return status: 2
Can anyone tell me what's wrong with that?
thansk,
JST

public void addRecord(int id, String name, int status)
throws SQLException {
status =3;In regular java you are never going to see this value (3) outside of that method. Java doesn't work that way.
So unless java inside the DB works really differently from regular java, you are going to have to pass something else.

Performance problem with sproc and out parameter ref cursor

Hi
I have sproc with Ref Cursor as an OUT parameter.
It is extremely slow looping over the ResultSet (does it record by record in the fetch).
so I have added setPrefetchRowCount(100) and setPrefetchMemorySize(6000)
pseudo code below:
string sqlSmt = "BEGIN get_tick_data( :v1 , :v2); END;";
Statement* s = connection->createStatement(sqlStmt);
s->setString(1, i1);
// cursor ( f1 , f2, f3 , f4 , i1 ) f for float type and i for interger value.
// 5 columns as part of cursor with 4 columns are having float value and
// 1 column is having int value assuming 40 bytes for one rec.
s->setPrefetchRowCount (100);
s->PrefetchMemorySize(6000);
s->registerOutParam(2,OCCICURSOR);
s->execute();
ResultSet* rs = s->getCursor(2);
while (rs->next()) {
// do, and do v slowly!
}

Hi,
I have the same problem. It seems, when retrieving cursor, that "setPrefetchRowCount" is not taking into account by OCCI. If you have a SQL statement like "SELECT STR1, STR2, STR3 FROM TABLE1" that works fine but if your SQL statement is a call to a stored procedure returning a cursor each row fetching need a roudtrip.
To avoid this problem you need to use the method "setDataBuffer" from the object "ResultSet" for each column of your cursor. It's easy to use with INT type and STRING type, a lit bit more complex with DATE type. But until now, I'm not able to do the same thing with REF type.
Below a sample with STRING TYPE (It's assuming that the cursor return only one column of STRING type):
try
l_Statement = m_Connection->createStatement("BEGIN :1 := PACKAGE1.GetCursor1(:2); END;");
l_Statement->registerOutParam(1, oracle::occi::OCCINUMBER, sizeof(l_CodeErreur));
l_Statement->registerOutParam(2, oracle::occi::OCCICURSOR);
l_Statement->executeQuery();
l_CodeErreur = l_Statement->getNumber(1);
if ((int) l_CodeErreur     == 0)
    char                         l_ArrayName[5][256];
    ub2                          l_ArrayNameSize[5];
    l_ResultSet = l_Statement->getCursor(2);
    l_ResultSet->setDataBuffer(1, l_ArrayName,   OCCI_SQLT_STR, sizeof(l_ArrayName[0]),   l_ArrayNameSize,   NULL, NULL);
    while (l_ResultSet->next(5))
      for (int i = 0; i < l_ResultSet->getNumArrayRows(); i++)
        l_Name = CString(l_ArrayName);
l_Statement->closeResultSet(l_ResultSet);
m_Connection->terminateStatement(l_Statement);
catch (SQLException &p_SQLException)
I hope that sample help you.
Regards
