!!!Answer!!!- From Technical Expert

In the Stored procedure :
create procedure emp_details () return refcursor as '
declare
empref refcursor;
begin
open empref for
SELECT emp.name,emp.age
FROM emp;
return empref;
end;

In the Java Code :

Connection con = null;
CallableStatement cstmt = null;
try
{
con = ConnectionPool.getConnection();

con.setAutoCommit(false);

// Setup the call.
cstmt = connection.prepareCall("{ ? = call emp_details () }");
// you can use
cstmt = connection.prepareCall("{call emp_details (?) }");

cstmt.registerOutParameter(1, OracleTypes.CURSOR);
cstmt.execute();

ResultSet rs = (ResultSet)cstmt.getObject(1);
while (rs.next())
{
String name = rs.getString(1);
int age = rs.getInt(2);
}
rs.close();
}
catch (SQLException e)
{
cstmt.close();
con.close();
}
