由NHib生成的DDL

Question

我有一个由Nhibernate的架构工具生成的Sql Server数据库，当我尝试输入已知的PartyId时遇到下面的错误，我只是没有得到错误。（即使我显示的日志输出来自使用NHibernate的测试运行，我也可以使用NHib生成的SQL Server数据库手动复制错误）

我认为 FK约束是说PartyId必须先存在，但就像我说的那样 - 确实存在。

我有SQL Server 2008管理工作室，但我很少使用它，更喜欢在我需要的极少数时间通过Visual Studio访问它。所以我有两个基本问题

如何从visual studio中看到sql server中的ddl？
如何调试和修复我的FK约束问题？

create table PartyNames (
    PartyNameId INTEGER not null,
   PartyId INTEGER not null,
   RequiredName TEXT not null,
   EverythingElse TEXT,
   ContextUsed TEXT,
   Salutation TEXT,
   EffectiveStart DATETIME,
   EffectiveEnd DATETIME,
   primary key (PartyNameId)
)

create table Parties (
    PartyId INTEGER not null,
   Type TEXT not null,
   primary key (PartyId)
)

外键可能未正确定义。这是目前的定义。

ALTER TABLE [dbo].[PartyNames]  WITH CHECK ADD  CONSTRAINT [Party_PartyName_FK] FOREIGN KEY([PartyNameId])REFERENCES [dbo].[Parties] ([PartyId])

应该如下。

ALTER TABLE [dbo].[PartyNames]  WITH CHECK ADD  CONSTRAINT [Party_PartyName_FK] FOREIGN KEY([PartyId])REFERENCES [dbo].[Parties] ([PartyId])

请注意，我已将PartyNameId换成PartyId。
