WPF_多个表新增
作者：互联网
每一个应用程序中都会存在这新增信息的模块，有时候我们可能是新增一个表，有时候是多个表一起新增，那么，我们要如何实现这功能呢，多个表新增其实和单表新增是一样的，只是多表新增比单表新增麻烦一点下面我给大家演示一下。
首先，我们要做的是在数据库中把存储过程写好，不同的开发人员用的数据库也不一样，我用的是SQL Server 2014 Management Studio,下面是我写的存储过程，我们把要新增的表的方法按顺序从基础表到业务表的格式编写好，然后给每一个新增的字段赋值，给到相应的值，同时在后面写出继承下一个表的ID值，好让下一个表来接收这个表传过去的ID值，具体的写法如下所示：
------------新增客户信息----------------------
IF @Type = 'Window_InsertClient'
BEGIN
INSERT
PW_Client(OpeningBankID, BranchID, CustomerReferred, ClientName, BrevityCode, Linkman, PostCode, Site, Phone, Faxes, E_mail, Remark, UnitCode)
VALUES(@OpeningBankID, @BranchID, @CustomerReferred, @ClientName, @BrevityCode, @Linkman, @PostCode, @Site, @Phone, @Faxes, @E_mail, @Remark, @UnitCode)
--给下一个表继承的ID值
select @@IDENTITY
END
--新增车辆信息
IF @Type = 'Window_InsertVehicle'
BEGIN
INSERT Basic_Vhicle(ClientID,CarTypeID, VehicleTypeID, CarID, ColourID, BusNumber, HackMan, DrPhone, IdentificationCard, ComeTime, FactoryNumber, ChassisNumber, EngineType, EngineNumber, VIN, SpeedBox)
VALUES(@ClientID,@CarTypeID, @VehicleTypeID, @CarID, @ColourID, @BusNumber, @HackMan, @DrPhone, @IdentificationCard, @ComeTime, @FactoryNumber, @ChassisNumber, @EngineType, @EngineNumber, @VIN, @SpeedBox)
END
第二步，写好存储之后，我们到服务端中写服务传送的编码，在编写代码之前我们要先建立一个操作契约，然后在写方法，实例化所有要新增的字段，然后在一一的赋值，调用数据库的方法来传输数据，打开数据通道，具体的写法如下所示：
//新增客户档案信息
//建立操作契约
[OperationContract]
public DataSet Window_InsertClient(int intOpeningIDBankID,int intBranchID, tring strCustomerReferred, string strClientName,string strLinkman, string strPostCode,string strSite,string strPhone,string strFaxes,string strE_mail, string strRemark,string strUnitCode)
{
SqlParameter[] mySqlParameters =
{
//定义传递参数，以及传递参数的类型
new SqlParameter("@Type",SqlDbType.NChar),
new SqlParameter("@OpeningBankID",SqlDbType.Int),
new SqlParameter("@BranchID",SqlDbType.Int),
new SqlParameter("@CustomerReferred",SqlDbType.NChar),
new SqlParameter("@ClientName",SqlDbType.NChar),
new SqlParameter("@Linkman",SqlDbType.NChar),
new SqlParameter("@PostCode",SqlDbType.NChar),
new SqlParameter("@Site",SqlDbType.NChar),
new SqlParameter("@Phone",SqlDbType.NChar),
new SqlParameter("@Faxes",SqlDbType.NChar),
new SqlParameter("@E_mail",SqlDbType.NChar),
new SqlParameter("@Remark",SqlDbType.NChar),
new SqlParameter("@UnitCode",SqlDbType.NChar),
};
//给对象赋值
mySqlParameters[0].Value = "Window_InsertClient";
mySqlParameters[1].Value = intOpeningIDBankID;
mySqlParameters[2].Value = intBranchID;
mySqlParameters[3].Value = strCustomerReferred;
mySqlParameters[4].Value = strClientName;
mySqlParameters[5].Value = strLinkman;
mySqlParameters[6].Value = strPostCode;
mySqlParameters[7].Value = strSite;
mySqlParameters[8].Value = strPhone;
mySqlParameters[9].Value = strFaxes;
mySqlParameters[10].Value = strE_mail;
mySqlParameters[11].Value = strRemark;
mySqlParameters[12].Value = strUnitCode;
DataTable myDataTable = myMethod.QueryDataTable("CustomerManagement", mySqlParameters);
DataSet myDataSet = new DataSet();
myDataSet.Tables.Add(myDataTable);
return myDataSet;
}
//1.3新增车辆信息表
//建立操作契约
[OperationContract]
public int Window_InsertVehicle(int intClientID,int intCarTypeID, int intVehicleTypeID,int intCarID, int intColourID, string strBusNumber, string strHackMan, string strDrPhone, string strIdentificationCard, DateTime datComeTime, string strFactoryNumber, string strChassisNumber, string strEngineType, string strEngineNumber, string strVIN, string strSpeedBox)
{
SqlParameter[] mySqlParameters =
{
new SqlParameter("@Type",SqlDbType.NChar),
new SqlParameter("@ClientID",SqlDbType.Int),
new SqlParameter("@CarTypeID",SqlDbType.Int),
new SqlParameter("@VehicleTypeID",SqlDbType.Int),
new SqlParameter("@CarID",SqlDbType.Int),
new SqlParameter("@ColourID",SqlDbType.Int),
new SqlParameter("@BusNumber",SqlDbType.NChar),
new SqlParameter("@HackMan",SqlDbType.NChar),
new SqlParameter("@DrPhone",SqlDbType.NChar),
new SqlParameter("@IdentificationCard",SqlDbType.NChar),
new SqlParameter("@ComeTime",SqlDbType.DateTime),
new SqlParameter("@FactoryNumber",SqlDbType.NChar),
new SqlParameter("@ChassisNumber",SqlDbType.NChar),
new SqlParameter("@EngineType",SqlDbType.NChar),
new SqlParameter("@EngineNumber",SqlDbType.NChar),
new SqlParameter("@VIN",SqlDbType.NChar),
new SqlParameter("@SpeedBox",SqlDbType.NChar),
};
//给对象赋值
mySqlParameters[0].Value = "Window_InsertVehicle";
mySqlParameters[1].Value = intClientID;
mySqlParameters[2].Value = intCarTypeID;
mySqlParameters[3].Value = intVehicleTypeID;
mySqlParameters[4].Value = intCarID;
mySqlParameters[5].Value = intColourID;
mySqlParameters[6].Value = strBusNumber;
mySqlParameters[7].Value = strHackMan;
mySqlParameters[8].Value = strDrPhone;
mySqlParameters[9].Value = strIdentificationCard;
mySqlParameters[10].Value = datComeTime;
mySqlParameters[11].Value = strFactoryNumber;
mySqlParameters[12].Value = strChassisNumber;
mySqlParameters[13].Value = strEngineType;
mySqlParameters[14].Value = strEngineNumber;
mySqlParameters[15].Value = strVIN;
mySqlParameters[16].Value = strSpeedBox;
int count = myMethod.UpdateData("CustomerManagement", mySqlParameters);
return count;
}
最后一步，也是最关键的一步，我们有先获取页面上所有字段的数值，判断字段的值为空还有数据类型是否正确，在判断没有问题的时候，在进行提交，点击保存按钮提交，程序会一步一步的循环，先把基础表的数据新增成功之后，然后在传输这个表的ID到下一个表那里进行新增判断，一步接着一步循环判断，直到将所有要新增的表新增成功，接这样，接完成一个多表新增的功能啦。
