INSERT 语句与 FOREIGN KEY 约束（光标）冲突答案

【问题标题】：The INSERT statement conflicted with the FOREIGN KEY constraint (Cursor)INSERT 语句与 FOREIGN KEY 约束（光标）冲突
【发布时间】：2016-04-25 01:30:23
【问题描述】：

我的任务是使用存储过程复制公司信息。作为技术主管的命令，我必须使用光标来完成我的任务。每当我运行 SP 时都会出现此错误。之前的问题中提到的人、地址等其他表都解决了，现在剩下的只有电话和电话链接表，这让我很头疼。

P/S：

EntityID = 5（公司）

下面是我的代码：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

现在每当我执行这个存储过程时，我都会得到如下所示的错误。我已经尝试将每个Phone 表与它的PhoneLink 表交换，以便首先插入电话仅链接到公司，但我仍然重复两次以下错误：

消息 547，级别 16，状态 0，过程 DuplicateCompanyInfo，第 150 行（假定）

INSERT 语句与 FOREIGN KEY 约束“FK_PhoneLink_PhoneId”冲突。冲突发生在数据库“CRM”、表“dbo.Phone”、列“Phon_PhoneId”中。

消息 547，级别 16，状态 0，过程 DuplicateCompanyInfo，第 160 行（假定）

INSERT 语句与 FOREIGN KEY 约束“FK_PhoneLink_PhoneId”冲突。冲突发生在数据库“CRM”、表“dbo.Phone”、列“Phon_PhoneId”中。

我知道这是一条非常直接的错误消息，但我无法修复它。我是 SQL 新手。请帮忙！

【问题讨论】：

请阅读如何创建minimal reproducible example。您发布了很多代码，请仅关注与问题相关的代码。
对不起先生，我已经编辑并缩短了它，删除了Person_Phone，只留下Company Phone，可以吗？
我不是替我问你，我是替你问你。您的问题越简短越清晰，就越有可能获得更快、更准确的答案。例如，我通常甚至懒得通读与你一样长的问题，而且我确信我不是唯一一个。请记住，我们都是在业余时间在这里，没有人在 stackoverflow 中回答问题而获得报酬。帮助我们帮助您，让您的问题尽可能简短、重点突出且易于阅读。
了解，我是新来的，所以不太了解。既然你提到了，我就更清楚了，谢谢你的指导。在我以后的问题中会记住这一点。

标签： sql sql-server stored-procedures cursor constraints

【解决方案1】：

你可以通过这个命令查看所有的约束：

exec sp_helpconstraint 'mytable'

似乎有重复。

【讨论】：

我检查了PhoneLink表，它确实有一个外键约束，约束名称FK_PhoneLink_PhoneID，status_enable为“启用”，status_for_replication为“Is_For_Replication”，constraint_keys为PLink_PhoneID和参考 CRM.dbo.Phone(Phon_PhoneId)。问题是我不知道如何解决这个约束问题。我是 SQL 新手，可能会问一些容易解决的问题，对此表示歉意。
我赞成并接受了您的回答，因为我相信您帮助我消除了一些困惑，但仍然希望您能指导我解决约束问题。谢谢
我已经通过将VALUES 中的所有@c_PLink_EntityID, @c_PLink_RecordID 更改为'5',@companyid 解决了这个问题，现在它工作得很好。还是谢谢！
