当我在Azure .Net后端制作迁移文件时,它会自动生成五个必填字段(Id,CreatedAt,UpdatedAt,Version,Deleted)和我的客户字段。它将Id定义为主键。更改EF6中的主键名称
public override void Up()
{
CreateTable(
"dbo.People",
c => new
{
Id = c.String(nullable: false, maxLength: 128,
annotations: new Dictionary<string, AnnotationValues>
{
{
"ServiceTableColumn",
new AnnotationValues(oldValue: null, newValue: "Id")
},
}),
PersonType = c.String(nullable: false, maxLength: 2),
FirstName = c.String(nullable: false, maxLength: 50),
MiddleName = c.String(maxLength: 50),
LastName = c.String(nullable: false, maxLength: 50),
Gender = c.String(nullable: false, maxLength: 1),
BirthDate = c.DateTime(nullable: false, storeType: "date"),
Version = c.Binary(nullable: false, fixedLength: true, timestamp: true, storeType: "rowversion",
annotations: new Dictionary<string, AnnotationValues>
{
{
"ServiceTableColumn",
new AnnotationValues(oldValue: null, newValue: "Version")
},
}),
CreatedAt = c.DateTimeOffset(nullable: false, precision: 7,
annotations: new Dictionary<string, AnnotationValues>
{
{
"ServiceTableColumn",
new AnnotationValues(oldValue: null, newValue: "CreatedAt")
},
}),
UpdatedAt = c.DateTimeOffset(precision: 7,
annotations: new Dictionary<string, AnnotationValues>
{
{
"ServiceTableColumn",
new AnnotationValues(oldValue: null, newValue: "UpdatedAt")
},
}),
Deleted = c.Boolean(nullable: false,
annotations: new Dictionary<string, AnnotationValues>
{
{
"ServiceTableColumn",
new AnnotationValues(oldValue: null, newValue: "Deleted")
},
}),
})
.PrimaryKey(t => t.Id)
.Index(t => t.CreatedAt, clustered: true);
}
我想这个主键名“ID”更改为“PERSONID”,所以我添加主键属性像下面
public class Person : EntityData
{
public string PersonId;
....
}
但没有奏效。 “Id”未被“PersonId”取代,只是作为客户字段添加到迁移文件中。所以,增加了[Key]属性,但是出错了,我得到了下面的消息。 “
”无法确定类型的组合主键排序。使用ColumnAttribute或HasKey方法指定组合主键的顺序。
如何更改主键名称?
您应该为重命名的列手动添加迁移代码。 –
