我是新來的流利NHibernate，我遇到了問題。流利的NHibernate/SQL Server 2008插入查詢問題
我已經映射定義如下：
public PersonMapping()
{
Id(p => p.Id).GeneratedBy.HiLo("1000");
Map(p => p.FirstName).Not.Nullable().Length(50);
Map(p => p.MiddleInitial).Nullable().Length(1);
Map(p => p.LastName).Not.Nullable().Length(50);
Map(p => p.Suffix).Nullable().Length(3);
Map(p => p.SSN).Nullable().Length(11);
Map(p => p.BirthDate).Nullable();
Map(p => p.CellPhone).Nullable().Length(12);
Map(p => p.HomePhone).Nullable().Length(12);
Map(p => p.WorkPhone).Nullable().Length(12);
Map(p => p.OtherPhone).Nullable().Length(12);
Map(p => p.EmailAddress).Nullable().Length(50);
Map(p => p.DriversLicenseNumber).Nullable().Length(50);
Component<Address>(p => p.CurrentAddress, m =>
{
m.Map(p => p.Line1, "Line1").Length(50);
m.Map(p => p.Line2, "Line2").Length(50);
m.Map(p => p.City, "City").Length(50);
m.Map(p => p.State, "State").Length(50);
m.Map(p => p.Zip, "Zip").Length(2);
});
Map(p => p.EyeColor).Nullable().Length(3);
Map(p => p.HairColor).Nullable().Length(3);
Map(p => p.Gender).Nullable().Length(1);
Map(p => p.Height).Nullable();
Map(p => p.Weight).Nullable();
Map(p => p.Race).Nullable().Length(1);
Map(p => p.SkinTone).Nullable().Length(3);
HasMany(p => p.PriorAddresses).Cascade.All();
}
public PreviousAddressMapping()
{
Table("PriorAddress");
Id(p => p.Id).GeneratedBy.HiLo("1000");
Map(p => p.EndEffectiveDate).Not.Nullable();
Component<Address>(p => p.Address, m =>
{
m.Map(p => p.Line1, "Line1").Length(50);
m.Map(p => p.Line2, "Line2").Length(50);
m.Map(p => p.City, "City").Length(50);
m.Map(p => p.State, "State").Length(50);
m.Map(p => p.Zip, "Zip").Length(2);
});
}
我的測試是
[Test]
public void can_correctly_map_Person_with_Addresses()
{
var myPerson = new Person("Jane", "", "Doe");
var priorAddresses = new[]
{
new PreviousAddress(ObjectMother.GetAddress1(), DateTime.Parse("05/13/2010")),
new PreviousAddress(ObjectMother.GetAddress2(), DateTime.Parse("05/20/2010"))
};
new PersistenceSpecification<Person>(Session)
.CheckProperty(c => c.FirstName, myPerson.FirstName)
.CheckProperty(c => c.LastName, myPerson.LastName)
.CheckProperty(c => c.MiddleInitial, myPerson.MiddleInitial)
.CheckList(c => c.PriorAddresses, priorAddresses)
.VerifyTheMappings();
}
GetAddress1（）（是，可怕的名字）已線路2 == NULL
的表格似乎要在sql server 2008中正確創建，但是測試失敗並出現SQLException「字符串或二進制數據將被截斷」。當我搶在SQL事件探查器的SQL語句，我得到
exec sp_executesql N'INSERT INTO PriorAddress (Line1, Line2, City, State, Zip,
EndEffectiveDate, Id) VALUES (@p0, @p1, @p2, @p3, @p4, @p5, @p6)',N'@p0
nvarchar(18),@p1 nvarchar(4000),@p2 nvarchar(10),@p3 nvarchar(2),@p4 nvarchar(5),@p5
datetime,@p6 int',@p0=N'6789 Somewhere Rd.',@p1=NULL,@p2=N'Hot
Coffee',@p3=N'MS',@p4=N'09876',@p5='2010-05-13 00:00:00',@p6=1001
通知的@ P1參數被設置爲爲nvarchar（4000），並傳遞一個NULL值。
爲什麼將參數設置爲nvarchar（4000）？我該如何解決它？
謝謝！
我的第一個理論認爲它與Line2參數有關是錯誤的。我向Line2添加了一個值，重新運行測試，並且仍然收到相同的錯誤。
exec sp_executesql N'INSERT INTO PriorAddress
(Line1, Line2, City, State, Zip, EndEffectiveDate, Id)
VALUES (@p0, @p1, @p2, @p3, @p4, @p5, @p6)',
N'@p0 nvarchar(18),@p1 nvarchar(6),@p2 nvarchar(10),@p3 nvarchar(2),@p4
nvarchar(5),@p5 datetime,@p6 int',
@p0=N'6789 Somewhere Rd.',
@p1=N'A test',
@p2=N'Hot Coffee',
@p3=N'MS',
@p4=N'09876',
@p5='2010-05-13 00:00:00',
@p6=1001
