【问题描述】：

以下 SQL 脚本用于 2 个相关表。当我尝试生成 EF 模型 (EF 6.02) 时，出现以下错误：

错误 13101：引用约束的 Dependent Role 中所有属性的类型必须与 Principal Role 中相应的属性类型相同。实体“agreements”上的属性“from_party_id”类型与引用约束“AGREE_PR_FK”中实体“party_relationships”上的属性“to_role_type_code”类型不匹配。

第一个表

CREATE TABLE [dbo].[party_relationships](
    [to_party_id] [numeric](8, 0) NOT NULL,
    [to_role_type_code] [varchar](10) NOT NULL,
    [from_party_id] [numeric](8, 0) NOT NULL,
    [from_role_type_code] [varchar](10) NOT NULL,
    [from_date] [datetime] NOT NULL,
    [priority_code] [varchar](10) NOT NULL,
    [status_code] [varchar](10) NOT NULL,
    [thru_date] [datetime] NULL,
    [pr_comment] [varchar](240) NULL,

 CONSTRAINT [PR_PK] PRIMARY KEY CLUSTERED 
 (
   [to_party_id] ASC,
   [from_party_id] ASC,
   [to_role_type_code] ASC,
   [from_role_type_code] ASC,
   [from_date] ASC

 ) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,  ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
 ) ON [PRIMARY]

第二张桌子

 CREATE TABLE [dbo].[agreements](

   [agreement_id] [numeric](8, 0) NOT NULL,
   [agreement_type_code] [varchar](10) NOT NULL,
   [to_party_id] [numeric](8, 0) NOT NULL,
   [from_party_id] [numeric](8, 0) NOT NULL,
   [pr_from_date] [datetime] NOT NULL,
   [from_role_type_code] [varchar](10) NOT NULL,
   [to_role_type_code] [varchar](10) NOT NULL,
   [agreement_date] [datetime] NOT NULL,
   [from_date] [datetime] NOT NULL,
   [thru_date] [datetime] NOT NULL,
   [description] [varchar](240) NOT NULL,

 CONSTRAINT [AGREE_PK] PRIMARY KEY CLUSTERED 
 (
  [agreement_id] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,  ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
 ) ON

[主要]

“AGREE_PR_FK”约束定义如下：

ALTER TABLE [dbo].[agreements]  WITH CHECK ADD  CONSTRAINT [AGREE_PR_FK] FOREIGN KEY([to_party_id], [from_party_id], [to_role_type_code], [from_role_type_code], [pr_from_date])
REFERENCES [dbo].[party_relationships] ([to_party_id], [from_party_id], [to_role_type_code], [from_role_type_code], [from_date])

EF 似乎正试图将相关列乱序排列。或者有什么我想念的！

我在 Windows 8.1 上使用 SQL Server 2012 和 VS 2013 Ultimate
