使用實體框架我以同樣的方式將兩個不同的對象保存到數據庫中。實體框架不會將對象保存到數據庫
一個目的被插入（它生成以下SQL）：
exec sp_executesql N'insert [dbo].[ImportJob]([SourceSystemId], [Start], [Source], [ImportType], [IsReadCompleted], [IsValidated], [IsImportCompleted])
values (@0, @1, @2, @3, @4, @5, @6)
select [Id]
from [dbo].[ImportJob]
where @@ROWCOUNT > 0 and [Id] = scope_identity()',N'@0 uniqueidentifier,@1 datetime2(7),@2 nvarchar(1000),@3 int,@4 bit,@5 bit,@6 bit',@0='1A908EAE-9438-49A3-9784-C9D84F99D217',@1='2013-08-29 14:46:58.3071350',@2=N'uploads\825d3e08-f795-45dc-aa8f-16e02dec3b29.xlsx',@3=1,@4=0,@5=0,@6=0
另一個目的沒有被插入，它不返回一個錯誤。唯一的SQL EF產生用於這個框架是這樣的：
exec sp_executesql N'declare @generated_keys table([Id] uniqueidentifier)
insert [dbo].[ImportOrganization]([ImportJobId], [Import_ExistingId], [Import_SourceSystemPk], [Import_IsNew], [Import_IsUpdated], [Import_IsRemoved], [SourcePk], [OrganizationTypeText], [Name], [OrganizationTypeId], [MissionStatement], [Address_Street], [Address_Number], [Address_Postcode], [Address_City], [PhoneNumber], [Website], [EmailAddress], [BankAccount], [BankAccountHolder])
output inserted.[Id] into @generated_keys

go
更新：該EF代碼
這是從GenericRepository.cs（基於該tutorial）：
public virtual void Insert(TEntity entity) {
dbSet.Add(entity);
}
和相應的UnitOfWork.cs：
public void Save() {
context.SaveChanges();
}
ImportOrganization item = new ImportOrganization();
item.Name = excelReader.GetString(1);
item.OrganizationTypeText = excelReader.GetString(2);
item.MissionStatement = excelReader.GetString(3);
item.Address = new DAL.Entities.Address
{
Street = excelReader.GetString(4),
Number = excelReader.GetString(5),
Postcode = excelReader.GetString(6),
City = excelReader.GetString(7)
};
item.PhoneNumber = excelReader.GetString(8);
item.Website = excelReader.GetString(9);
item.EmailAddress = excelReader.GetString(10);
item.BankAccount = excelReader.GetString(11);
item.BankAccountHolder = excelReader.GetString(12);
item.Import = new ImportEntity
{
SourceSystemPk = excelReader.GetString(0)
};
item.ImportJob = _importJob;
item.ImportJobId = _importJob.Id;
item.SourcePk = excelReader.GetString(0);
調用插件和保存方法：
unitOfWork.ImportOrganizationRepository.Insert(item);
unitOfWork.Save();
爲什麼不EF創建一個新的對象導入查詢失敗的對象？
你可以顯示你的代碼以及導入語句嗎？ – BenM
那麼沒有例外？你有沒有用linq pad來測試這個問題，以確定你是代碼中的錯誤還是sql？ – BentOnCoding
它不保存在linqpad中。沒有錯誤。並且數據庫中沒有項目（是的，我正在查看正確的數據庫） – jao
