sql-server - 标识列的显式值？

Question

我正在尝试备份我的第一个表 DocumentManagement.tbDocumentsHistory 中的数据并将其保存在 DocumentManagement.tbDocuments 上

并且由于 DocumentManagement.tbDocuments 具有 ID IDENTITY_INSERT 列，因此将引发此错误

An explicit value for the identity column in table 'DocumentManagement.tbDocuments' can only be specified when a column list is used and IDENTITY_INSERT is ON.

当我使用这段代码时

DELETE FROM DocumentManagement.tbDocumentsHistory
OUTPUT DELETED.* INTO DocumentManagement.tbDocuments 
FROM    DocumentManagement.tbDocumentsHistory
WHERE   DocumentID=@DocumentID

我尝试使用此代码关闭 DocumentManagement.tbDocuments 上的 IDENTITY_INSERT

SET IDENTITY_INSERT DocumentManagement.tbDocuments ON 
        DELETE FROM DocumentManagement.tbDocumentsHistory
            OUTPUT DELETED.* INTO DocumentManagement.tbDocuments 
            FROM    DocumentManagement.tbDocumentsHistory
        WHERE   DocumentID=@DocumentID
        SET IDENTITY_INSERT DocumentManagement.tbDocuments OFF

我仍然面临同样的错误!

我的表格描述:

CREATE TABLE [DocumentManagement].[tbDocuments](
[DocumentID] [bigint] IDENTITY(1,1) NOT NULL,
[DocumentNameEn] [nvarchar](max) NULL,
[DocumentNameAr] [nvarchar](max) NULL,
[DocumentDescriptionEn] [nvarchar](max) NULL,
[DocumentDescriptionAr] [nvarchar](max) NULL,
[CreatedOn] [datetime2](7) NULL,
[ModifiedOn] [datetime2](7) NULL,
[AddedBy] [bigint] NULL,
[modifaiedBy] [bigint] NULL,
[PhysicalName] [nvarchar](max) NULL,
[Extension] [nvarchar](15) NULL,
[DocumentTypeID] [bigint] NULL,
[PhysicalPath] [nvarchar](max) NULL,


CONSTRAINT [PK_tbDocuments] PRIMARY KEY CLUSTERED([DocumentID] ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]

) 在[主要]上

CREATE TABLE [DocumentManagement].[tbDocumentsHistory](
[DocumentID] [bigint] NOT NULL,
[DocumentNameEn] [nvarchar](max) NULL,
[DocumentNameAr] [nvarchar](max) NULL,
[DocumentDescriptionEn] [nvarchar](max) NULL,
[DocumentDescriptionAr] [nvarchar](max) NULL,
[CreatedOn] [datetime2](7) NULL,
[ModifiedOn] [datetime2](7) NULL,
[AddedBy] [bigint] NULL,
[modifaiedBy] [bigint] NULL,
[PhysicalName] [nvarchar](max) NULL,
[Extension] [nvarchar](15) NULL,
[DocumentTypeID] [bigint] NULL,
[PhysicalPath] [nvarchar](max) NULL, CONSTRAINT [PK_tbDocumentsHistory] PRIMARY KEY CLUSTERED([DocumentID] ASC)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]) ON [PRIMARY]

您需要修改您的 INSERT 语句并添加一个包含标识列名称的列列表才能使其正常工作。

任何使用标识插入的 INSERT 语句都需要一个列列表，如下所示:

CREATE TABLE dbo.Tab 
(
   ID INT IDENTITY NOT NULL PRIMARY KEY, 
   Name VARCHAR(40) NOT NULL
)

SET IDENTITY_INSERT dbo.Tab ON
GO

INSERT INTO dbo.Tab (ID, Name) VALUES (3000, 'Groucho')
GO

SET IDENTITY_INSERT dbo.Tab OFF
