来源：互联网发布：淘宝美工助手官网编辑：程序博客网时间：2024/04/29 22:59

我已经建立了用access建立了图书管理系统的数据库,并建立了图书明细表.也弄了数据源.执行别的jsp的文件都成功，但唯独连接数据库的都没用。请各位帮帮我

//建立数据库连接，jspdata为ODBC数据源名称
Connection con = DriverManager.getConnection("jdbc:odbc:jspdata");
//建立Statement对象
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
//建立ResultSet(结果集)对象，并执行SQL语句
ResultSet rs = stmt.executeQuery("select * from 图书明细表");

<th width="200">日期</th>

while(rs.next())

<td><%= rs.getString(3) %></td>
<td bgcolor="#f6f6f8"><%= rs.getString(4) %></td>
<td><%= rs.getString(5) %></td>

}
rs.close();
stmt.close();
con.close();

如果能看到表格中的数据，说明连接数据库成功！</p>

执行后显示

Apache Tomcat/5.5.20

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
String s = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=d:/jsp/oa/database/oa_database.mdb";

    }
    catch(ClassNotFoundException e){
      System.out.print(e);
    }
    try{
      String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=C://Inetpub//wwwroot//Yeyinews//news.mdb";
      Connection conn = DriverManager.getConnection(url);
      Statement stmt = conn.createStatement();
      .........
}
catch(Xeception e){
}

上面的代码实际使用过，应该没有什么问题
