IDENTITY_INSERT设置为OFF - 如何打开它？

Question

我有一个删除的文件存档数据库，它存储了被删除的文件的ID，我希望管理员能够恢复该文件（以及链接文件的相同ID）。我不想将identity_insert从整个表中删除，因为增加一个很有效。在我插入到TBL_Content存储过程我有这样的事情

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
SET IDENTITY_INSERT tbl_content ON 
GO 

ALTER procedure [dbo].[spInsertDeletedIntoTBLContent] 
@ContentID int, 
...insert command... 
SET IDENTITY_INSERT tbl_content OFF 

但我不断收到同样的错误：

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

任何帮助吗？

Answer 1

如果您改为对设置在存储过程中的标识插入？它看起来像只在更改存储过程时才设置它，而不是在实际调用它时。尝试：

ALTER procedure [dbo].[spInsertDeletedIntoTBLContent] 
@ContentID int, 

SET IDENTITY_INSERT tbl_content ON 

...insert command... 

SET IDENTITY_INSERT tbl_content OFF 
GO 

Answer 2

我相信它需要在单个查询批处理中完成。基本上，GO语句将您的命令分成多个批次，这就是问题所在。将其更改为：

SET IDENTITY_INSERT tbl_content ON 
/* GO */ 

...insert command... 

SET IDENTITY_INSERT tbl_content OFF 
GO 

Answer 3

您不应该将identity_Insert设置为ON，插入记录然后将其关闭？

像这样：

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
SET IDENTITY_INSERT tbl_content ON 
GO 

ALTER procedure [dbo].[spInsertDeletedIntoTBLContent] 
@ContentID int, 
SET IDENTITY_INSERT tbl_content ON 
...insert command... 
SET IDENTITY_INSERT tbl_content OFF

的参考：http://technet.microsoft.com/en-us/library/aa259221%28v=sql.80%29.aspx

我的表名为Genre与Id，Name和SortOrder

，我使用的代码的3列是：

SET IDENTITY_INSERT Genre ON 

INSERT INTO Genre(Id, Name, SortOrder)VALUES (12,'Moody Blues', 20) 

Answer 5

在上方添加此行查询

SET IDENTITY_INSERT tbl_content ON 

Answer 6

提醒

SQL Server只允许一个表有IDENTITY_INSERT属性设置为ON。

这不起作用：

SET IDENTITY_INSERT TableA ON 
SET IDENTITY_INSERT TableB ON 
... INSERT ON TableA ... 
... INSERT ON TableB ... 
SET IDENTITY_INSERT TableA OFF 
SET IDENTITY_INSERT TableB OFF 

相反：

SET IDENTITY_INSERT TableA ON 
... INSERT ON TableA ... 
SET IDENTITY_INSERT TableA OFF 
SET IDENTITY_INSERT TableB ON 
... INSERT ON TableB ... 
SET IDENTITY_INSERT TableB OFF
