超级急:cybase的TabularResults.ResultSet

05-04-15 iamyy2002

在CORBA中传递ResultSet,重新得到的ResultSet没了数据,为什么?

// 在此输入java代码

import java.sql.ResultSet;
import java.sql.Connection;

public class Sample {

	public static void main(String[] args) {
	
	Connection con = null;	
	try{
		
		Class.forName("org.postgresql.Driver");
		
		con = java.sql.DriverManager.getConnection("jdbc:postgresql://localhost/mydb","postgres","password");
		java.sql.Statement stm = con.createStatement();
		String sql = "select \"userID\",\"name\" from logindb;";
		
		ResultSet rs = stm.executeQuery(sql);			
	
   	    while(rs.next()){
   	    	int userID = rs.getInt("userID");
   	    	String name = rs.getString("name");
   	    	System.out.println("userID="+userID+"    name="+name);
   	    }
		
   	    TabularResults.ResultSet trrs = com.sybase.CORBA.jdbc11.IDL.getResultSet(rs);		
		
   	    java.sql.ResultSet resultset = com.sybase.CORBA.jdbc11.SQL.getResultSet(trrs);
   	    
   	    while(resultset.next()){
   	    	int userID = resultset.getInt("userID");
   	    	String name = resultset.getString("name");
   	    	System.out.println("userID="+userID+"    name="+name);
   	    }
   	    System.out.println("over");
		
	}catch(Exception e){
		e.printStackTrace();
	}finally {
		try {
			con.close();
		}catch (java.sql.SQLException sqle) {
			System.out.println("close connection error: " + sqle.toString());
		}
	}	
		
		
		
	}
}

我以为ResultSet转换过程中游标会自动复原,原来不是。

低级错误。
