SQL Server 2016 时态表为“GENERATED”抛出不正确的语法答案

求助，由于某种原因我无法让它工作。

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[MYTABLE]
(
    [MyTableId] [INT] IDENTITY(1,1) NOT NULL,
    [Description] [NVARCHAR](255) NULL,
    [DisplayOrder] [INT] NOT NULL,
    [VALIDFROM] [DATETIME2](7) GENERATED ALWAYS AS ROW START NOT NULL,
    [VALIDTO] [DATETIME2](7) GENERATED ALWAYS AS ROW END NOT NULL,
    PERIOD FOR SYSTEM_TIME ([VALIDFROM], [VALIDTO]),
    CONSTRAINT [PK_MYTABLE] PRIMARY KEY CLUSTERED ([MyTableId] ASC)
)  ON [PRIMARY]
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
WITH (SYSTEM_VERSIONING = ON (HISTORY_TABLE = [dbo].[MYTABLE_History]))
GO

我不断收到这些错误：

消息 102，第 15 级，状态 1，第 24 行
'GENERATED' 附近的语法不正确。

消息 319，第 15 级，状态 1，第 29 行
关键字“with”附近的语法不正确。如果这个语句是一个公用表表达式、一个 xmlnamespaces 子句或一个更改跟踪上下文子句，则前面的语句必须以分号结束。

消息 319，第 15 级，状态 1，第 30 行
关键字“with”附近的语法不正确。如果这个语句是一个公用表表达式、一个 xmlnamespaces 子句或一个更改跟踪上下文子句，则前面的语句必须以分号结束。

这是 SQL Server 2016 安装。

有什么帮助吗？

检查括号。

【解决方案1】：

在语法上有点偏离。将您的第一个 WITH 移动到您的约束，因为它已绑定到文件组之前。

CREATE TABLE [dbo].[MYTABLE](
    [MyTableId] [int] IDENTITY(1,1) NOT NULL,
    [Description] [nvarchar](255) NULL,
    [DisplayOrder] [int] NOT NULL,
    [VALIDFROM] [datetime2](7) GENERATED ALWAYS AS ROW START NOT NULL,
    [VALIDTO] [datetime2](7) GENERATED ALWAYS AS ROW END NOT NULL,
    PERIOD FOR SYSTEM_TIME ([VALIDFROM], [VALIDTO]),
    CONSTRAINT [PK_MYTABLE] 
        PRIMARY KEY CLUSTERED ([MyTableId] ASC)
        WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
) ON [PRIMARY]
 WITH (SYSTEM_VERSIONING = ON (HISTORY_TABLE = [dbo].[MYTABLE_History]))

【解决方案2】：

你的语法有误。第一个 WITH 与您的索引有关，因此应该在此之后。

CREATE TABLE [dbo].[MYTABLE](
    [MyTableId] [int] IDENTITY(1,1) NOT NULL,
    [Description] [nvarchar](255) NULL,
    [DisplayOrder] [int] NOT NULL,
    [VALIDFROM] [datetime2](7) GENERATED ALWAYS AS ROW START NOT NULL,
    [VALIDTO] [datetime2](7) GENERATED ALWAYS AS ROW END NOT NULL,
    PERIOD FOR SYSTEM_TIME ([VALIDFROM], [VALIDTO]),
    CONSTRAINT [PK_MYTABLE] PRIMARY KEY CLUSTERED ([MyTableId] ASC) WITH (PAD_INDEX = OFF,STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
) ON [PRIMARY] with (SYSTEM_VERSIONING = ON (HISTORY_TABLE = [dbo].[MYTABLE_History]))
