I need to seed data for my local development purpose in the following Temporal Table, the start date should be old. The given Table Schema is
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 )
)
I need to Insert some old dated data into this table.
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
)
I'm getting the following Error.
Cannot insert an explicit value into a GENERATED ALWAYS column in table 'DevDB.dbo.Contact'. Use INSERT with a column list to exclude the GENERATED ALWAYS column, or insert a DEFAULT into GENERATED ALWAYS column.
Kindly assist me how to add or Update a old dataed data into this Temporal Table
Finally I found a solution
Step #1: Need to Switch it OFF the
SYSTEM_VERSIONING
Step #2: Need to drop the
PERIOD FOR SYSTEM_TIME
Step #3: Insert required record with past date
Step #4: Need to Add the
PERIOD FOR SYSTEM_TIME
Step #5: Need to Switch it ON the
SYSTEM_VERSIONING
That's it...
