public class DoControl {
    public  static  void main(String[] args)throws SQLException, ClassNotFoundException, UnsupportedEncodingException {
     
String sql = "select * from Export_Output where id between "+(100*(pageIndex-1)+1)+" and "+100*(pageIndex) +" order by id desc";
 PreparedStatement pstm = DataBaseUtil.getConn().prepareStatement(sql);
ResultSet rs = pstm.executeQuery();
while (rs.next()) {
 
String name = rs.getString(“name”);
}
rs.close();
}
}

今天要做大数据处理，拿access做练习，顺便学习一下Java连接access数据库问题。

Java 连接access数据库，以及解决中文乱码问题，还有查询分页问题。

解决中文乱码的时候：尝试用 String name = rs.getString(“name”);

name = new String(name.getBytes(“utf-8”),”GBK”或者

name = new String(name.getBytes(“iso-8859-1”),”GBK”)等等解决不了问题。

最后用Properties prop =new Properties();prop.put("charSet", "gbk");

问题解决。

public class DataBaseUtil {
    privatestatic Connectionconn =null;
 
    publicstaticConnection getConn()throws ClassNotFoundException, SQLException
    {
       if (conn==null)
       {
          Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          String url = "jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=E:\\2.accdb";
           Properties prop = new Properties();   
            prop.put("charSet","gbk");   //解决中文乱码
            conn = DriverManager.getConnection(url,prop);
          // conn = DriverManager.getConnection(url);
       }
      
       returnconn;
   
    }
   
}

//100:显示条数

//pageIndex:当前页数
