编辑：我修好了。我所做的是将数据库的所有者更改为与我用来连接它的用户不同的东西。检查数据库所有者：

select name, suser_sname(owner_sid) from sys.databases

要更改所有者：

ALTER AUTHORIZATION ON DATABASE::ISS TO sa;

差不多就是这样，我仍然不知道这是什么原因，但它确实有效，很酷。（也许以前的 dbowner 缺少一些权利？）

这让我头痛太久了，我完全不知道为什么会这样。长话短说，我从以下网址获取了 Mark Nischalke 的项目：http: //www.codeproject.com/Articles/12335/Using-SqlDependency-for-data-change-events。该项目有一个 SQL 脚本来创建数据库，并且 SqlDependecy 在他的项目/数据库上触发。现在我知道我以前的数据库有问题，我复制了他的脚本并创建了我自己的数据库。除了表格（显然）之外，一切都是相同的。这意味着我的 SqlDependency 应该可以工作，因为我有一个与另一个可以工作的数据库相同配置的数据库；但不......它不起作用。此时，在我的项目中，我更改了 SqlDependecy 以检查他的用于通知的数据库并且它可以工作，所以这不是我的项目中的 .NET 问题。然后我尝试让他项目中的 SqlDependency 检查我的数据库，不，仍然无法正常工作。在这两种情况下，我都使用相同的连接字符串、集成的安全性但不同的初始目录。谢谢你的帮助。

（还要注意，MessageQueue 是在我的数据库上创建的，并在我关闭项目 SqlDependecy.Stop 但事件未触发时删除）

这是他的数据库创建脚本

您的基础表结构中可能有不正确的数据类型或其他一些非法问题。我建议查看这篇文章并确保您满足“支持的 SELECT 语句”部分下的所有条件：

确保你已经运行

ALTER DATABASE kmsdta SET ENABLE_BROKER;

如果此语句挂起，请使用此启用代理

alter database kmsdta set enable_broker with rollback immediate;

你还要确保你在你的 Dababase 中运行了这个

CREATE QUEUE ContactChangeMessages;

CREATE SERVICE ContactChangeNotifications
  ON QUEUE ContactChangeMessages

以及使用 SqlDependency 监控表时要考虑的一些重要事项

  1. 在前面的代码中，您会注意到我的 SQL 查询没有使用“ ”通配符来返回所有列。您必须返回所需的确切列。如果你使用“ ”，你会产生不好的后果。

  2. 同样在前面的代码中，您会注意到我的 SQL 查询包含“两部分”表名。这也是必需的。仅使用“TableName”而不是“owner.TableName”也会导致不良后果。

一个简单查询的例子：

select OrderID from dbo.[DTAOrders];
