一本关于JBuilder 应用开发的书籍,希望大家喜欢,其实我没看过的,

  public String[] getemail()
  {
//函数的返回值是数组的首地址
    String sql;
String email[]=new String[_n];
//生成sql语句
sql="select top  "+_n+"  * from email";
//把sql语句设置到queryDataSet1当中
queryDataSet1.setQuery(new com.borland.dx.sql.dataset.QueryDescriptor(database1, sql , null, true, Load.ALL));
//执行查询
    queryDataSet1.executeQuery() ;
int i;
//循环将结果集添加到数组当中
    for (i=0; (i<_n && i<queryDataSet1.rowCount() ) ;i++)
    {
email[i]=queryDataSet1.getString("email") ;
queryDataSer1.next();
}
//返回数组的首地址
    return email;
  }
