Question

I have a mapping like this for a DateTime column:

...
Map(x => x.Created).Column("CREATED")
                   .Access.Property()
                   .CustomType<DateTime>()
                   .CustomSqlType("datetime")
                   .Not.Nullable();
...

In my code I define

outboxCriteria.Add(Restrictions.Eq("Created", startDate));

where ‘startDate’ is of type DateTime.

When looking at the created SQL I see for the above criteria

...
    and Created = 2/14/2012 12:00:00 AM
...

which is not correct. I would expect NHibernate to create

...
    and Created = '2/14/2012 12:00:00 AM'
...

I also observed that same problem with String types.

Map( x => x.ReceiverName).Column("UserName")
                         .CustomType("string")
                         .Access.Property()
                         .CustomSqlType("nvarchar(256)")
                         .Nullable()
                         .Length(256);

The resulting SQL does not put strings in quotes:

...
    and UserName = Paul
...

instead of

...
    and UserName = 'Paul'
...

The mapping works quite well except these problems.

What am I making wrong?

Answer 1

specifying .CustomSqlType("nvarchar(256)") renders Length() to a noop. Also string and datetime are no customeTypes/customSqlTypes. Maybe NHibernate is confused by them.

Remove all but Map( x => x.ReceiverName).Column("UserName").Length(256).
