我的Java代碼。 10.74.44.65是服務器的位置ip。 數據庫連接，但我不能執行sql查詢。

import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.ResultSet; 
import java.sql.SQLException; 
import java.sql.Statement; 

public class Main { 
    public static void main(String[] argv) { 
     try { 
      Class.forName("com.ibm.db2.jcc.DB2Driver"); 
     } 
     catch (ClassNotFoundException e) { 
      e.printStackTrace(); 
      return; 
     } 
     Connection conn; 
     Statement stmt; 
     ResultSet rs; 
     try { 
      conn = DriverManager.getConnection("jdbc:db2://10.74.44.65:51020/SAMPLE","db2admin","Us3admin"); 
      System.out.println("Connection successfully"); 
      stmt=conn.createStatement(); 
      System.out.println("Test 1"); 
      rs=stmt.executeQuery("select * from staff"); 
      System.out.println("Test 2"); 
      while (rs.next()) { 
       System.out.println("Employee number = " + rs.getString(1)); 
       } 
     } catch (SQLException e) { 
      e.printStackTrace(); 
      return; 
     } 
    } 

}

"SQLCODE=-204, SQLSTATE=42704" is a DB2 error code indicating 'object does not exist'

^{（來源：http://www-01.ibm.com/support/docview.wss?uid=swg21613531）。}

SQLERRMC=DB2ADMIN.STAFF則表示表STAFF不存在於用戶DB2ADMIN中，或者該用戶未被授權使用該表。
