如何使用 SQL Server 2008 打开和关闭 IDENTITY_INSERT? [英] How to turn IDENTITY_INSERT on and off using SQL Server 2008?

问题描述

当 IDENTITY_INSERT 设置为 OFF 时，为什么我在执行插入时出错?

Why am I getting an error doing an insert when IDENTITY_INSERT is set to OFF?

如何在 SQL Server 2008 中正确打开它?是使用 SQL Server Management Studio 吗?

How do I turn it on properly in SQL Server 2008? Is it by using SQL Server Management Studio?

我已经运行了这个查询:

I have run this query:

SET IDENTITY_INSERT Database. dbo. Baskets ON

然后我在控制台中收到消息，表明命令已成功完成.但是，当我运行该应用程序时，它仍然给我如下所示的错误:

Then I got the message back in the console that the Command(s) completed successfully. However when I run the application, it still gives me the error shown below:

Cannot insert explicit value for identity column in table 'Baskets' when 
IDENTITY_INSERT is set to OFF.

推荐答案

Via SQL as per MSDN

Via SQL as per MSDN

SET IDENTITY_INSERT sometableWithIdentity ON

INSERT INTO sometableWithIdentity 
    (IdentityColumn, col2, col3, ...)
VALUES 
    (AnIdentityValue, col2value, col3value, ...)

SET IDENTITY_INSERT sometableWithIdentity OFF

完整的错误消息会告诉您确切地出了什么问题...

The complete error message tells you exactly what is wrong...

当 IDENTITY_INSERT 设置为 OFF 时，无法为表 'sometableWithIdentity' 中的标识列插入显式值.

Cannot insert explicit value for identity column in table 'sometableWithIdentity' when IDENTITY_INSERT is set to OFF.
