ormlite-servicestack - 您如何配置 ormlit 以支持不是主键的自动增量列？

Question

我有一张 table

CREATE TABLE [dbo].[ServiceTestCase](
    [SSN] [int] IDENTITY(600000001,1) NOT NULL,
    [Description] [varchar](max) NULL,
    [EmbeddedResponse] [varchar](max) NULL,
    [ResponseType] [varchar](50) NULL,
    [DocumentType] [varchar](50) NULL,
    [Id] [uniqueidentifier] NOT NULL,
    [ServiceType] [varchar](50) NOT NULL,
 CONSTRAINT [PK_TestCase] PRIMARY KEY CLUSTERED 

我的课

public class ServiceTestCase
    {
        public ServiceTestCase ()
        {

        }
        public string ServiceType { get; set; }
          [ServiceStack.DataAnnotations.AutoIncrement]
        public Guid Id { get; set; }
        [ServiceStack.DataAnnotations.AutoIncrement]
        public long SSN { get; set; }
        public string Description { get; set; }
        public string EmbeddedResponse { get; set; }
        public EmbeddedResponseType ResponseType { get; set; }
        public EmbeddedDocumentType DocumentType { get; set; }
    }

当我调用 db.Insert ( new ServiceTestCase {/* Id = testId, */ServiceType = "Credit"} );
我收到以下错误:
System.Data.SqlClient.SqlException:当 IDENTITY_INSERT 设置为 OFF 时，无法为表“ServiceTestCase”中的标识列插入显式值。

如何让 ormlite 忽略自动增量字段，以便我可以插入一个项目？

您可以使用 [ServiceStack.DataAnnotations.AutoIncrement] 注释 Id .
