通过林格向实体向新实体分配主要价值
原标题:Confusion in assigning primary key values to new entities via Linq to Entities

当我利用我已在Kingk服务器上创建的数据库所产生的模型在欧洲复兴开发银行中建立一个新的实体时,我显然可以选择在我宣布新实体时将实体的识别(主要人物)列入我的代码。

For example when I create a new instance of my Value table in my code like this:

<编码> 价值新 数值 = 数值。

我通过了若干字,即12至25岁。

Value newValue = Value.CreateValue(12);

but when I check the Value table s data in SQL Server the primary key value valID for the new entity is assigned to something other than 12, for example 7. Why is this happening?

提前感谢。

检查贵国在数据库中的主要关键位置是AUTONUMBER。 (企业经理采用表格设计模式和核对栏目。) 这意味着数据库将无视你所传递的任何价值,并产生主要的关键。
