Boolean System.Boolean DbType.Boolean Default when no type attribute specified.
Byte System.Byte DbType.Byte Default when no type attribute specified.
Char System.Char DbType.StringFixedLength - 1 char Default when no type attribute specified.
DateTime System.DateTime DbType.DateTime - ignores the milliseconds Default when no type attribute specified.

PersistentEnum A System.Enum The DbType for the underlying value. Do not specify type="PersistentEnum" in the mapping. Instead specify the Assembly Qualified Name of the Enum or let NHibernate use Reflection to "guess" the Type. The UnderlyingType of the Enum is used to determine the correct DbType.

Timestamp System.DateTime DbType.DateTime - as specific as database supports. type="Timestamp" must be specified.

CultureInfo System.Globalization.CultureInfo DbType.String - 5 chars for culture Default when no type attribute specified.
Binary System.Byte[] DbType.Binary Default when no type attribute specified.

String System.String DbType.String Default when no type attribute specified.

Large Object Mapping Types

BinaryBlob System.Byte[] DbType.Binary type="BinaryBlob" must be specified. Entire field is read into memory.
