问题描述

嗨
我看到的下面的代码从数据库中获取特定的值.您使用什么来获取表内所有值的集合

Hi
Code below as I see it get specific value from database. What do you use to get the collection of all values inside your tables

resultSet = statement.executeQuery("SELECT password,username FROM tbl_Credantials");
            while (resultSet.next())
            {
                  String userName = resultSet.getString("username ");

            }

我需要的东西与下面的代码相同

I need something that works the same as this code below

OleDbCommand cmd = new OleDbCommand("SELECT * FROM tbl_Credantials", con);


                DataTable dTable = new DataTable();
                OleDbDataAdapter adapter = new OleDbDataAdapter(cmd);
                adapter.SelectCommand = cmd;
                adapter.Fill(dTable);

                return dTable;

推荐答案

Java没有.net样式的DataTable对象，所以您必须创建自己的.

Java does not have the .net style DataTable object, so you will have to create your own.
