Can't get ByCode mapping to produce not nullable varbinary(max)
---------------------------------------------------------------
Key: NH-2739
URL: http://216.121.112.228/browse/NH-2739
Project: NHibernate
Issue Type: Bug
Components: Mapping by-code
Affects Versions: 3.2.0Beta1
Reporter: Michael Teper
Priority: Major
Trying to map the following class:
public class MyData
{
public byte[] Data { get; set; }
}
to 'varbinary(max) (not null)' field in SQL Server 2008.
mapper.Class<MyData>(map =>
{
map.Property(x => x.Data, m => m.Length(int.MaxValue));
map.Property(x => x.Data, m => m.NotNullable(true));
});
produces 'image(null)'

-----------------------------------
Nullability might be a problem with SchemaAction = SchemaAutoAction.Recreate. When I blew away the database and started from scratch, the image column was created correctly as not null.
Would still like to know if there is anything I can do to have NH generate varbinary(max) in place of image.
Thanks!

I tried adding the following bit to specify the type:
map.Property(x => x.Data, m => m.Type<BinaryBlobType>());
but got the following error:

---------------------------------
You can use the override accepting the IType:
map.Type(NHibernateUtil.BinaryBlob)
btw the problem is that the BinaryBlobType has 'internal' ctor.

Michael Teper commented on NH-2739:
-----------------------------------
That worked, thank you!
Does your last comment mean that the type needs to open up a parameterless constructor?
