Sql MS IDENTITY_INSERT设置为OFF

我目前正在处理我的SQL Server项目。我遇到了这个错误，不知道如何修复它。我检查了其他的栈柱，它对我不起作用。我也试过YouTube。在INSERT语句前后，我观看了一段视频，并尝试打开

设置标识插入（表名）和关闭
设置标识插入（表名）。我的代码是否有问题，不允许我在项目中插入数据

我收到的错误消息如下：

当identity_insert设置为OFF时，无法在表“Vet”中为identity列插入显式值

Msg 544，16级，状态1，第68行

当identity\u insert设置为OFF时，无法在表“Owner”中为identity列插入显式值

味精544，第16级，状态1，第81行

当identity\u insert设置为OFF时，无法在表“约会”中插入identity列的显式值

味精544，第16级，状态1，第89行

当identity\U insert设置为OFF时，无法在表“Pet”中为identity列插入显式值

请设定

将IDENTITY\u INSERT设置为ON之前
并在每个INSERT语句的后面设置IDENTITY_INSERT OFF

问候

您必须在运行其余代码的同一会话中设置IDENTITY\u INSERT。在为另一个表启用标识之前，还必须先禁用标识插入。大概是这样的：

SET IDENTITY_INSERT owner ON

您的代码中没有任何地方使用
将标识插入设置为打开
，但是，您正在尝试显式地将值插入标识列。您还遇到了
约会
和
宠物
插入数据的问题。因为您正在每个表中引用另一个表，所以无法插入数据。您正在尝试插入
约会
数据，但没有任何
宠物
数据。为什么在
Pet
表上有
Appointment\u Num
？@WEI\u DBA很好，没有必要在那里设置该列
