将Access数据库中数据导入到SQL Server中的详细方法实例

        string sql = "";
        OleDbConnection con = CreateCon();//创建数据库连接
        con.Open();
        DataSet ds = new DataSet(); //创建数据集
        sql = "select * from Score";
        OleDbDataAdapter myCommand = new OleDbDataAdapter(sql,con);//创建数据适配器
        myCommand.Fill(ds, "Score");
        myCommand.Dispose();
        DataTable DT = ds.Tables["Score"];
        con.Close();
        myCommand.Dispose();
        for (int j = 0; j < DT.Rows.Count; j++)//循环ACCESS中数据获取相应信息
        {
            string sqlstr = "";
            string ID = DT.Rows[j][0].ToString();
            string UserName = DT.Rows[j][1].ToString();
            string PaperName = DT.Rows[j][2].ToString();
            string UserScore = DT.Rows[j][3].ToString();
            string ExamTime = DT.Rows[j][4].ToString();
            string selsql = "select count(*) from AccessToSQL where 用户姓名='" + UserName + "'";
            if (ExScalar(selsql) > 0)//判断数据是否已经添加
            {
                Label1.Visible = true;
                Label1.Text = "<script language=javascript>alert('该Access数据库中数据已经导入SQL数据库中!');location='AccessToSQL.aspx';</script>";
            }
            else
            {
                string AccessPath = Server.MapPath("UserScore.mdb");//获取ACCESS数据库路径
                //应用OPENROWSET函数访问 OLE DB 数据源中的远程数据所需的全部连接信息
                sqlstr = "insert into AccessToSQL(ID,用户姓名,试卷,成绩,考试时间)Values('" + ID + "','" + UserName + "','" + PaperName + "','" + UserScore + "','" + ExamTime + "')";
