所谓事务，就是把多件事情当做一件事情来处理。也就是大家同在一条船上！
由一个事务来完成多个表的同步操作，要么都执行成功，要么都不成功.下面举个例子，用C#实现Access数据库事务的处理方法：
向一个表提交数据，同时更新另一个表中的数据
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.OleDb;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
string id = "";
string strCon = System.Configuration.ConfigurationManager.AppSettings["ConnectStr"].ToString();
OleDbConnection con = new OleDbConnection(strCon);
OleDbDataAdapter adp = new OleDbDataAdapter();
OleDbDataAdapter adp1 = new OleDbDataAdapter();
try
{
con.Open();
OleDbTransaction tra = con.BeginTransaction(); //创建事务，开始执行事务
adp = new OleDbDataAdapter("select * from 序号表", con);
adp.SelectCommand.Transaction = tra;
adp1=new OleDbDataAdapter("select * from 节目表", con);
adp1.SelectCommand.Transaction = tra;
OleDbCommandBuilder thisBuilder = new OleDbCommandBuilder(adp);
OleDbCommandBuilder thisBuilder1 = new OleDbCommandBuilder(adp1);
DataSet ds = new DataSet();
adp.Fill(ds,"aa");//添加数据集
id = ds.Tables["aa"].Rows[0][1].ToString();
Int64 s = 0;
s = Convert.ToInt64(id) + 1;
id = s.ToString("0000000#");
ds.Tables["aa"].Rows[0][1] = id;
adp.Update(ds,"aa");//执行修改一个表的事务
adp1.Fill(ds,"bb");
DataRow dr=ds.Tables["bb"].NewRow();
dr["ProID"]=id;
dr["ProName"]="ProName";
dr["ProTime"]="2";
dr["ProIsFinish"]="3";
dr["ProBgColor"]="4";
dr["ProBgPic"]="5";
dr["ProStyle"]="6";
dr["MissionName"]="7";
dr["ProDescription"]="8";
ds.Tables["bb"].Rows.Add(dr);
adp1.Update(ds,"bb");
tra.Commit();//关闭事务
}
catch (Exception ex)
{
}
finally
{
con.Close();
}
}
注：Access的事务不支持自动锁定（经试验已经证实），因此Access最好用于本机的程序，b/s中做好不要用，除非你不用事务处理~~！
