映射大串功能NHibernate

Question

我与Oracle数据库的工作，和我想这个类映射：

public class Book 
{ 
    public virtual int Id { get; private set; } 
    public virtual string Author { get; set; } 
    public virtual string Title { get; set; } 
    public virtual string Text { get; set; } 
} 

有了这个映射类：

public class BookMap : ClassMap<Book> 
{ 
    public BookMap() 
    { 
     Id(x => x.Id); 
     Map(x => x.Author); 
     Map(x => x.Title); 
     Map(x => x.Text); 
    } 
} 

但列它生成我的类型是NVARCHAR（255），并且Book.Text属性的远远超过255个字符。

如何将其映射到可包含非常大的字符串的类型（例如CLOB）？

Answer 1

public class BookMap : ClassMap<Book> 
{ 
    public BookMap() 
    { 
     Id(x => x.Id); 
     Map(x => x.Author); 
     Map(x => x.Title); 
     Map(x => x.Text).CustomSqlType("CLOB"); 
    } 
} 

或

public class BookMap : ClassMap<Book> 
{ 
    public BookMap() 
    { 
     Id(x => x.Id); 
     Map(x => x.Author); 
     Map(x => x.Title); 
     Map(x => x.Text).Length(500); // nvarchar(500) 
    } 
}
