Question

我正在使用Insight micro ORM对sql server 2008 R2数据库进行批量插入。当我执行批量插入时，我得到此异常。我不知道为什么会发生这种情况。我确保属性名称和sql服务器表列名称是正确的类型和名称

这是C＃代码

Public static void DoBulkInsert(string permissionName)
{

using (IToolTransaction tran = Connection.OpenWithTransactionAs<IToolTransaction>())
                  {
                  List<AuditRemovePermisison> audList = new List<AuditRemovePermisison>();
                  list<int> userIds = getUserIds();
                  foreach(int userId in userIds)
                  {
                    audList.Add(new AuditRemovePermisison
                  {
                     ToolId = null,                     
                     UserId = userId,
                     Name = permissionName,
                     CreatedDate = DateTime.Now
                  });
                  }
                      tran.UsersDeactivateByPermissionName
                      tran.BulkCopy("RJ.AuditRemovePermission", audList, configure: (InsightBulkCopy bulk) =>
                          {
                              bulk.BatchSize = 5000;
                          },transaction:tran);                      
                      tran.Commit();
                  }
}

和POCO是

public  class AuditRemovePermisison
    {

        public int? ToolId { get; set; }        
        public int UserId { get; set; }
        public string Name { get; set; }
        public DateTime CreatedDate { get; set; }
    }

[Sql（Schema =“RJ”）]    公共接口IToolTransaction：IDbConnection，IDbTransaction     {
           void UsersDeactivateByPermissionName（string PermissionName）;
    }

Answer 1

在Glimpse包装器和自动生成的界面中，似乎存在双重包装连接的错误。

我已经打开了一个github问题来跟踪这个问题：

与此同时，如果您关闭该场景的一瞥分析，它应该可以工作。我认为它无论如何都不能描述批量拷贝。

Insight Micro ORM会在批量复制上引发异常
