SQL Server 自动生成触发器并阻止我在 Web 应用程序上的 CRUD 操作

Question

过去几周，我在 ASP.NET Core Web 应用程序上添加或更新存储在本地 SQL Server 上的数据时遇到了一个奇怪的触发问题。我的数据库上只有表和视图，没有触发器，但是当我尝试通过 Linq 方法语法查询添加或更新数据时，Visual Studio 会抛出错误：

Microsoft.EntityFrameworkCore.DbUpdateException：无法保存更改，因为目标表具有数据库触发器。请相应地配置您的实体类型，请参阅 https://aka.ms/efcore-docs-sqlserver-save-changes-and-triggers 了解更多信息。

SqlException：如果 DML 语句包含 OUTPUT 子句而不包含 INTO 子句，则该语句的目标表“tbl_Countries”不能有任何启用的触发器。

我找到了克服这个问题的解决方案。解决方案是声明 Visual Studio 每个表都有 SQL Server 自动生成的触发器。

builder.Entity<tbl_Countries>().ToTable(tb => tb.HasTrigger("tr_dbo_tbl_Countries_05f5745b-9b96-4d32-b09e-4be5651c2649_Sender"));
base.OnModelCreating(builder);

一开始工作得很好，但 SQL Server 有时会生成一个新的触发器，我需要再次在 Visual Studio 中更改触发器的名称。 我不知道为什么 SQL Server 自动生成触发器以及如何克服它。如果我等待一段时间并刷新数据库中的表，触发器就会消失，但下次我尝试添加或更新数据时会自动生成。

我正在使用 SignalR 在我的 Web 项目上获取实时数据和 cookie 会话。

由于 SignalR 的依赖性，我还在 SQL Server 数据库上使用了

enable_broker

：

alter database myProjectDB 
    set enable_broker with rollback immediate

  This exception was originally thrown at this call stack:

Inner Exception 1:

SqlException: The target table 'tbl_Countries' of the DML statement cannot have any enabled triggers if the statement contains an OUTPUT clause without INTO clause.

这是自动生成的触发器之一：

使用 SignalR 或 SQL 表依赖进行实时同步时，会自动创建此触发器。我们无法确定当前正在使用哪一个。 我们可以选择以一定的时间间隔检查触发器，然后将新触发器放在那里并删除旧触发器。我不知道这有多准确，这只是一个猜测解决方案。
