Fluent NHibernate/SQL Server 2008 insert query problem
- by Mark
Hi all,
I'm new to Fluent NHibernate and I'm running into a problem.
I have a mapping defined as follows:
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);
});
}
My test is
[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() (yeah, horrible name) has Line2 == null
The tables seem to be created correctly in sql server 2008, but the test fails with a SQLException "String or binary data would be truncated." When I grab the sql statement in SQL Profiler, I get
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
Notice the @p1 parameter is being set to nvarchar(4000) and being passed a NULL value.
Why is it setting the parameter to nvarchar(4000)? How can I fix it?
Thanks!
