【MSSQL】用事务一次处理多条SQL语句
作者:Dezai.CN / 发布于2013/1/29/ 779
只有所有操作都成功则成功，只要有一条数据操作失败，则回滚。
后台写事务：

        /// <summary>
        /// 执行多条SQL语句，实现数据库事务。
       /// </summary> access数据库
       /// <param name="SQLStringList">多条SQL语句</param>  
        public static void ExecuteSqlTran(List<string> SQLStringList)
        {
            using (OleDbConnection conn = new OleDbConnection(SqlHelper.ConString))
            {
                conn.Open();
                OleDbCommand cmd = new OleDbCommand();
                cmd.Connection = conn;
                OleDbTransaction tx = conn.BeginTransaction();
                cmd.Transaction = tx;
                try
                {
                    for (int n = 0; n < SQLStringList.Count; n++)
                    {
                        string strsql = SQLStringList[n].ToString();
                        if (strsql.Trim().Length > 1)
                        {
                            cmd.CommandText = strsql;
                            cmd.ExecuteNonQuery();
                        }
                    }
                    tx.Commit();
                }
                catch (System.Data.OleDb.OleDbException E)
                {
                    tx.Rollback();
                    throw new Exception(E.Message);
                }
            }
        }

        /// <summary>
        /// 执行多条SQL语句，实现数据库事务。
        /// </summary>sql2000数据库
        /// <param name="SQLStringList">多条SQL语句</param> 
        public static void ExecuteSqlTran(List<string> SQLStringList)
        {
            using (SqlConnection conn = new SqlConnection(SqlHelper.ConString))
            {
                conn.Open();
                SqlCommand cmd = new SqlCommand();
                cmd.Connection = conn;
                SqlTransaction tx = conn.BeginTransaction();
                cmd.Transaction = tx;
                try
                {
                    for (int n = 0; n < SQLStringList.Count; n++)
                    {
                        string strsql = SQLStringList[n].ToString();
                        if (strsql.Trim().Length > 1)
                        {
                            cmd.CommandText = strsql;
                            cmd.ExecuteNonQuery();
                        }
                    }
                    tx.Commit();
                }
                catch (System.Data.SqlClient.SqlException E)
                {
                    tx.Rollback();
                    throw new Exception(E.Message);
                }
            }
        }

前台调用：

try
{
    //1.查出会员余额
    decimal usermoney = SqlDal.EntityUserinfo.GetModel(int.Parse(cookieUserID)).Money;
    //2.修改余额
    decimal Zmoney = usermoney + moAD.Commission;
    //写SQL语句
    List<string> SQLStringList = new List<string>();
    string clickSql = "insert into [user] (name,age)values('" + 小名 + "','“+4岁+”')";
    string userSql = "update [class] set [name]='" + 幼儿园 + "' where id=" + 2 + " ";
    SQLStringList.Add(clickSql);
    SQLStringList.Add(userSql);
    SqlDal.SqlHelper.ExecuteSqlTran(SQLStringList);

    //数据库操作成功
    //提示
    CommonClass.Xmls xmls1 = new CommonClass.Xmls();
    string path1 = CommonClass.Unit.GetMapPath(@"/Admin/Configs/SysSettingInfo.config");
    string ClickTishi = xmls1.GetXmlNode(path1, "SysSettingInfo/ClickTishi");
    //替换字符
    ClickTishi = ClickTishi.Replace("[$]", moAD.Commission.ToString("0.00"));
    context.Response.Write(ClickTishi); //输出
}
catch (Exception ex)
{
    //Response.Write(ex.Message);
    context.Response.Write("操作失败！" + ex.Message); //输出
}
试试其它关键字
　处理多条SQL　
同语言下
可能有用的
