SQL Server：无法通过 SSMS 编辑数据
Posted
技术标签:
【中文标题】SQL Server：无法通过 SSMS 编辑数据【英文标题】：SQL Server : Unable to edit data through SSMS 【发布时间】：2017-05-11 14:13:31 【问题描述】：我处于一种奇怪的情况，我无法通过 SSMS 更新视图中的行。我收到此错误：
错误来源：SQL Server 管理数据工具 错误消息：更新或删除的行值要么不使行唯一，要么改变多行
但是，我可以在 Visual Studio 中更新它们，也可以通过 TSQL Update 语句进行更新。这看起来像是 SQL Server Management Studio 中的一个错误。
感谢任何帮助/建议。

附：之前我直接从视图中更新 newFileName 列，因为我将该列拆分为 8 个不同的列，这 8 个新列在 Visual Studio 中显示为禁用
【问题讨论】：
天哪 ..... cursor 在 trigger 内......这就是 绝对最糟糕的事情你可以为你的表现做！你真的应该尝试找到一种方法来 AVOID 游标 - 最肯定是在触发器内部！ 我不喜欢它们中的任何一个，但考虑到界面开发人员的紧迫性和缺乏，这是我能想到的最好的方法 【参考方案1】：真的不知道你更新了什么。
重要！如果视图引用了多个基表，则不能删除一行。您只能更新属于单个基表的列。
重要！如果视图引用了多个基表，则不能插入一行。

【讨论】：
这有什么关系，而不是尝试插入或删除。您可以在具有多个表的视图中进行插入，这就是触发器的用途。 ***.com/questions/18555917/… 试图更新生成视图的基础表【参考方案2】：我需要做的就是在触发器开始时设置 NOCOUNT OFF。
