【问题描述】：
我目前正在处理我的 SQL Server 项目。我遇到了这个错误，不知道如何解决。我检查了其他堆栈帖子，但它对我不起作用。我也试过 YouTube。我看了一段视频，并在我的插入语句之前和之后尝试了SET IDENTITY_INSERT (Table name) ON&SET IDENTITY_INSERT (Table name) OFF。我的代码是否有问题不允许我将数据插入到我的项目中？

我收到的错误消息：

当 IDENTITY_INSERT 设置为 OFF 时，无法在表“所有者”中插入标识列的显式值。消息 544，第 16 层，状态 1，第 81 行

当 IDENTITY_INSERT 设置为 OFF 时，无法为表“Pet”中的标识列插入显式值。
【问题讨论】：
-
您在代码中的任何地方都没有使用
SET IDENTITY INSERT ON，但是，您正试图向标识列显式插入一个值 -
您还遇到了
Appointment和Pet插入数据的问题。因为您在每个表中引用另一个表，您将无法插入数据。您正在尝试插入Appointment数据而没有任何Pet数据。为什么Pet表上有Appointment_Num？ -
@WEI_DBA 很好看，没有那个专栏的意义
