功能NHibernate導致「算術溢出錯誤轉換數字數據類型數值」上插入/保存

Question

此代碼生成一個「算術溢出錯誤轉換數字數據類型數字」

Session.Save(new Keyword 
{ 
    Approved = true, 
    Custom = false, 
    Value = "toto", 
    Language = "en" 
}); 

的關鍵字的映射是以下

public class KeywordMap : ClassMap<Keyword> 
{ 
    public KeywordMap() 
    { 
     Table("PRODUCTS_Keywords"); 

     Id(x => x.Id, "keywordID").GeneratedBy.Identity(); 

     Map(x => x.Value, "keyword") 
      .Not.Nullable(); 

     Map(x => x.Language, "language") 
      .Not.Nullable(); 

     Map(x => x.Approved, "approved") 
      .Not.Nullable(); 

     Map(x => x.Custom, "custom") 
      .Not.Nullable(); 
    } 
} 

關鍵字的實體是在F ollowing

public class Keyword 
{ 
    public virtual Int64 Id { get; private set; } 
    public virtual string Value { get; set; } 
    public virtual string Language { get; set; } 
    public virtual bool Approved { get; set; } 
    public virtual bool Custom { get; set; } 
} 

這是表PRODUCTS_Keyword的表現在我的數據庫（我使用MSSQL 2008 R2）

CREATE TABLE [dbo].[PRODUCTS_Keywords](
    [keywordID] [bigint] IDENTITY(1,1) NOT NULL, 
    [keyword] [nvarchar](50) NOT NULL, 
    [language] [char](2) NOT NULL, 
    [approved] [bit] NOT NULL, 
    [custom] [bit] NOT NULL, 
PRIMARY KEY CLUSTERED 

這是關鍵字

    <class xmlns="urn:nhibernate-mapping-2.2" name="Keyword, Main, Version=1.4.0.0, Culture=neutral, PublicKeyToken=null" table="PRODUCTS_Keywords"> 
    <id name="Id" type="System.Int64, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> 
     <column name="keywordID" /> 
     <generator class="identity" /> 
    </id> 
    <property name="Value" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> 
     <column name="keyword" not-null="true" /> 
    </property> 
    <property name="Language" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> 
     <column name="language" not-null="true" /> 
    </property> 
    <property name="Approved" type="System.Boolean, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> 
     <column name="approved" not-null="true" /> 
    </property> 
    <property name="Custom" type="System.Boolean, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> 
     <column name="custom" not-null="true" /> 
    </property> 
    </class> 
</hibernate-mapping> 

導出的映射

這是堆棧跟蹤

目前，有266 016條記錄表PRODUCTS_Keywords和馬克斯（keywordID）爲8 942 223

有什麼問題的原因以及如何解決？

謝謝

，似乎值得商榷關於您的設置是有set訪問是私有的唯一的事情。這可能是好的，但我只見過在這些情況下使用公共和保護。

你可以顯示通過流利生成的sql語句嗎？在配置Fluent時使用ShowSql（），它將向控制檯輸出它試圖執行的SQL。實際的錯誤消息似乎是SQL錯誤消息。
