C#_C#处理Access中事务的方法,本文实例讲述了C#处理Access中

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();}}uDs码友部落

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~~!uDs码友部落

Access不能像SQL server一样直接执行多条语句,但是把多条语句绑成事务还是可以一起执行的. 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uDs码友部落
