在2005年我使用java开发的一套BS系统。对初学者很有帮助。

				package com.forcg;
				import java.sql.*;
				
				public class DBconn 
				{String DBDriver="sun.jdbc.odbc.JdbcOdbcDriver";
				String ConnStr="jdbc:odbc:mytable";
				Connection conn = null;
				ResultSet rs = null;
				
				public DBconn() {
				try 
				{
					Class.forName(DBDriver);
				}
				catch(java.lang.ClassNotFoundException e) {
					System.err.println("DBconn (): " + e.getMessage());
				}
				}
				
				
				public ResultSet executeQuery(String sql) {
				rs = null;
				try
				{
					conn = DriverManager.getConnection(ConnStr);
				    Statement stmt = conn.createStatement();
				    rs = stmt.executeQuery(sql);
				}
				catch(SQLException ex) {
					System.err.println("aq.executeQuery:"+ex.getMessage());
				   }
				return rs;
				 }
				}
