在临时表中使用旧日期播种数据-SQL Server

Question

我需要在下面的临时表中为我的本地开发目的填充数据，开始日期应该是旧的。给定的表架构为

CREATE TABLE [dbo].[Contact](
    [ContactID] [uniqueidentifier] NOT NULL,
    [ContactNumber] [nvarchar](50) NOT NULL,
    [SequenceID] [int] IDENTITY(1,1) NOT NULL,
    [SysStartTime] [datetime2](0) GENERATED ALWAYS AS ROW START NOT NULL,
    [SysEndTime] [datetime2](0) GENERATED ALWAYS AS ROW END NOT NULL,
 CONSTRAINT [PK_Contact] PRIMARY KEY NONCLUSTERED 
(
    [ContactID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],
    PERIOD FOR SYSTEM_TIME ([SysStartTime], [SysEndTime])
) ON [PRIMARY]
WITH
(
    SYSTEM_VERSIONING = ON (HISTORY_TABLE = [dbo].[ContactHistory] , DATA_CONSISTENCY_CHECK = ON )
)

我需要在此表中插入一些过时的数据。

INSERT INTO dbo.Contact
(
    ContactID,
    ContactNumber,
    --SequenceID - this column value is auto-generated
    SysStartTime,
    SysEndTime
)
VALUES
(
    NEWID(), -- ContactID - uniqueidentifier
    N'9999912345', -- ContactNumber - nvarchar
    -- SequenceID - int
    '2017-09-01 06:26:59', -- SysStartTime - datetime2
    NULL -- SysEndTime - datetime2
)

我收到以下错误。

无法将明确的值插入表’DevDB.dbo.Contact’的GENERATED ALWAYS列中。将INSERT与列列表一起使用以排除GENERATED
ALWAYS列，或将DEFAULT插入GENERATED ALWAYS列。

请帮助我如何添加或更新旧dataed数据到这个 态表

Answer 1

终于我找到了解决方案

第1步 ：需要切换它 关闭 了SYSTEM_VERSIONING

ALTER TABLE dbo.Contact SET (SYSTEM_VERSIONING = OFF);

步骤＃2 ：需要删除PERIOD FOR SYSTEM_TIME

ALTER TABLE dbo.Contact DROP PERIOD FOR SYSTEM_TIME

步骤＃3 ：插入要求的记录以及过去的日期

INSERT INTO dbo.Contact
(
    ContactID,
    ContactNumber,
    SysStartTime,
    SysEndTime
)
VALUES
(
    NEWID(), -- ContactID - uniqueidentifier
    N'1234567890', -- ContactNumber - nvarchar
    '2014-09-13 00:00:00', -- SysStartTime - datetime2
    '9999-12-31 23:59:59' -- SysEndTime - datetime2
)

步骤＃4 ：需要添加PERIOD FOR SYSTEM_TIME

ALTER TABLE dbo.Contact
ADD PERIOD FOR SYSTEM_TIME ([SysStartTime], [SysEndTime])

步骤＃5 ：需要切换它 开 了SYSTEM_VERSIONING

ALTER TABLE dbo.[Contact] SET (SYSTEM_VERSIONING = ON
 (HISTORY_TABLE=dbo.[ContactHistory],DATA_CONSISTENCY_CHECK=ON)
);

而已…
