SQL多表插入事务处理
新建两个需统一事务处理的数据表
--学生信息表
CREATE TABLE [dbo].[Student](
[Id] [int] NOT NULL,
[Name] [varchar](50) NOT NULL,
[Age] [int] NOT NULL,
[Address] [nvarchar](50) NOT NULL,
CONSTRAINT [PK_Student] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] --学生成绩表
CREATE TABLE [dbo].[Result](
[Id] [int] IDENTITY(1,1) NOT NULL,
[StudentId] [int] NOT NULL,
[Subject] [varchar](50) NOT NULL,
[Score] [int] NOT NULL,
CONSTRAINT [PK_Result] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
代码中定义相应的实体类
public class Student
{
/// <summary>
///编号
/// </summary>
public int StudentId { get; set; }
/// <summary>
/// 姓名
/// </summary>
public string Name { get; set; }
/// <summary>
/// 年龄
/// </summary>
public int Age { get; set; }
/// <summary>
/// 地址
/// </summary>
public string Address { get; set; }
}
public class Result
{
/// <summary>
/// 学生编号
/// </summary>
public int StudentId { get; set; }
/// <summary>
/// 科目
/// </summary>
public string Subject { get; set; }
/// <summary>
/// 得分
/// </summary>
public int Score { get; set; }
}
初始化对象
Student student = new Student { StudentId = , Name = "Johh", Age = , Address = "中国上海" };
List<Result> resultList = new List<Result> { new Result { StudentId = , Subject = "语文", Score = },
new Result { StudentId = , Subject = "数学", Score = } };
定义一个把实体转换成XML的通用方法
/// <summary>
/// 把实体对象转换成Xml
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="model"></param>
/// <returns></returns>
protected string GetSerializer<T>(T model)
where T : new()
{
StringBuilder sb = new StringBuilder();
XmlSerializer x = new XmlSerializer(typeof(T));
StringWriter sw = new StringWriter(sb);
x.Serialize(sw, model);
return ProcessXmlStr(sb.ToString());
}
/// <summary>
/// 处理Xml中的特殊字符
/// </summary>
/// <param name="xml"></param>
/// <returns></returns>
public string ProcessXmlStr(string xml)
{
string xmlHead = "<?xml version=\"1.0\" encoding=\"utf-16\"?>";
string strSpace = "\r\n";
string strXlnsxsi = " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"";
string strXlnsxsd = "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"";
string strNil = "xsi:nil=\"true\"";
return xml.Replace(xmlHead, "").Replace(strSpace, "").Replace(strXlnsxsi, "").Replace(strXlnsxsd, "")
.Replace("> <", "><").Replace(strNil, "").Replace("<", "<").Replace(">", ">");
}
把实体转换成Xml格式
/// <summary>
/// 获取单个对象sql执行脚本
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="parameterValue">参数值</param>
/// <param name="procName">存储过程名称</param>
/// <param name="procIndex">存储过程执行顺序</param>
/// <param name="parameterName">参数名称</param>
/// <returns></returns>
protected string GetSingleExcuteSql<T>(T parameterValue, string procName, int procIndex, string parameterName) where T : new()
{
StringBuilder sb = new StringBuilder();
sb.Append(string.Format("<SP Name=\"{0}\" ProcIndex=\"{1}\" ParameterName=\"{2}\" ParameterValue=\"{3}\"></SP>",
procName, procIndex, parameterName, parameterValue != null ? GetSerializer(parameterValue) : ""));
return sb.ToString();
}
/// <summary>
/// 获取sql执行脚本
/// </summary>
/// <param name="student">学生信息</param>
/// <param name="resultList">学生成绩</param>
/// <returns></returns>
protected string GetExcuteSql(Student student, List<Result> resultList)
{
StringBuilder sb = new StringBuilder();
sb.Append(GetSingleExcuteSql<Student>(student, "Proc_Insert_Student", (int)SqlExcuteIndex.CurrentStep, "StudentXml"));
sb.Append(GetSingleExcuteSql<List<Result>>(resultList, "Proc_Insert_Result", (int)SqlExcuteIndex.CurrentStep + , "ResultXml"));
return sb.ToString();
}
组装Xml，并统一执行
/// <summary>
/// 使用事务进行存储
/// </summary>
/// <returns></returns>
public bool ExcuteTransaction()
{
return new TestDAL().ProcessOverall("<SPList>"+GetExcuteSql(student,resultList)+"</SPList>");
} /// <summary>
/// 事件统一执行
/// </summary>
/// <param name="allInfo"></param>
/// <returns></returns>
public bool ProcessOverall(string allInfo)
{
bool result = false;
SqlParameter param = new SqlParameter("@AllInfo", allInfo);
result = Excute("proc_flow_ProcessOverall", param, CommandType.StoredProcedure);
return result;
}
