If you are using ORACLE drivers and classes.
This sample program shows Oracle JDBC REF CURSOR functionality, creating a PL/SQL package that includes a stored function that returns a REF CURSOR type. The sample retrieves the REF CURSOR into a result set object.
* This sample shows how to call a PL/SQL function that opens
* a cursor and get the cursor back as a Java ResultSet.
import java.sql.*;
import java.io.*;
import oracle.jdbc.driver.*;
class RefCursorExample
public static void main (String args [])
throws SQLException
// Load the driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database
// You can put a database name after the @ sign in the connection URL.
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@", "scott", "tiger");
// Create the stored procedure
init (conn);
// Prepare a PL/SQL call
CallableStatement call =
conn.prepareCall ("{ ? = call java_refcursor.job_listing (?)}");
// Find out all the SALES person
call.registerOutParameter (1, OracleTypes.CURSOR);
call.setString (2, "SALESMAN");
call.execute ();
ResultSet rset = (ResultSet)call.getObject (1);
// Dump the cursor
while (rset.next ())
System.out.println (rset.getString ("ENAME"));
// Close all the resources
rset.close();
call.close();
conn.close();
// Utility function to create the stored procedure
static void init (Connection conn)
throws SQLException
Statement stmt = conn.createStatement ();
stmt.execute ("create or replace package java_refcursor as " +
" type myrctype is ref cursor return EMP%ROWTYPE; " +
" function job_listing (j varchar2) return myrctype; " +
"end java_refcursor;");
stmt.execute ("create or replace package body java_refcursor as " +
" function job_listing (j varchar2) return myrctype is " +
" rc myrctype; " +
" begin " +
" open rc for select * from emp where job = j; " +
" return rc; " +
" end; " +
"end java_refcursor;");
stmt.close();
