ReferentialConstraint中的依赖属性映射到存储生成的列。柱:

首先,感谢您花时间阅读本文。尝试使用EF更新数据库时遇到了一些困难。我之前在另一个项目中使用过相同的方法,所以我认为这个问题可能在数据库中,但我只是没有看到它。数据库是SQL 2005中的遗留数据库,命名约定有很多不足之处,因此我一直通过HasColumnName方法将不一致的名称映射到更一致的名称:如。

        modelBuilder.Entity<Case_Person_1>().ToTable("dbo.Case_Person_1");
        modelBuilder.Entity<Case_Person_1>().Property(c => c.Id).HasColumnName("CaseNumber");

我将我的问题与其他类似的问题进行了比较,并进行了调查,以验证外键关系是否指向正确的方向,并且身份仅在PK上。当我没有显式设置数据生成选项时,该命令触发数据库,​​但它失败b / c我插入0作为我的键,选项显式设置为OFF。我可以在SQL事件探查器中看到这一点。当我添加Identity选项时,我得到了参照约束错误。

我已经失去了2天,而且我已经没有达到解决方案了,而且我的绳子已经结束了。 顺便说一句,在我的其他项目中,我不需要使用DatabaseGeneratedOption来装饰我的POCO,但是我没有在插入时遇到任何错误。我不知道这是不是SQL 2005的东西,或者我是否遗漏了其他东西......

3 个答案:

答案 0 :(得分:2)

它只用了大约一个小时的头撞击,但我使用另一个回复的暗示来解决问题。缺点是EntityFramework对某些关系感到困惑(或者我的描述使用了流利的表达式)。

我终于咬了一口子并清理了数据库中列的一些名称并使它们成为“常规”,即tableName + Id删除了我的流利表达式并且它有效。

我还在一个表上取出了一个复合键,添加了一个Id字段,并使复合键成为唯一索引。

我希望这有助于其他人。

我还确认我怀疑在使用SQL Server 2008时不需要标识注释。正在使用的数据库是2005年。

[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]

答案 1 :(得分:2)

我有同样的错误。最终追溯到一个不正确的关系。我在数据库中的两个主键之间进行链接,而不是主要和外来。

答案 2 :(得分:0)

我不得不手动删除.edmx中的错误引用。
