Question

我的服务器上有很多数据库，最近有一个数据库（我是dbo）已经无法通过SSMS访问。当我在＆＃39; object explorer＆＃39;中展开表节点时对于此数据库，我收到以下错误：

子查询返回的值超过1。当子查询遵循=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或子查询用作表达式时，不允许这样做。（.Net SqlClient数据提供程序）

但是，我可以在该数据库上成功执行选择，而其他用户没有遇到此问题。

我有;

检查我的登录信息是否设置错误。
检查我的用户是否设置了错误。
重新启动SQL Server引擎。
使用安装程序实用程序修复SSMS。

非常感谢你的意见，我很难过（以前从未发生过这种情况）。

编辑：使用SQL事件探查器跟踪并导致此事件后，我解压缩查询并在SSMS会话窗口中运行它。返回的结果来自错误的数据库。

编辑：除此之外，我运行了dbcc checkdb（databasename）并且没有返回任何错误，然后我为master做了同样的事情，没有返回任何错误。

编辑：扩展表文件夹时执行的查询：

编辑：作为解决方法，我重新安装了SSMS 2014.我可以通过此处访问我的表格。

Answer 1

您的数据库没有任何问题， SSMS 16.5.2 已知问题，并已向产品团队报告过。如果它导致太多麻烦，请恢复到之前发布的SSMS。有关详细信息，请参阅此thread。

显然，这仅在数据库具有多个稀疏列的表时才会发生。

Answer 2

试试吧

SELECT 
    NAME
FROM [base].SYS.triggerS
WHERE parent_class_desc = 'DATABASE'

获取触发器名称并执行以下步骤

DISABLE TRIGGER [dbo].[trigger_name]
