SQL Server 2016时态表为“抛出不正确的语法”；“生成”；

救命啊，不知什么原因，我不能让它工作

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

我不断地发现这些错误：

味精102，第15级，状态1，第24行
“已生成”附近的语法不正确

Msg 319，第15级，状态1，第29行
关键字“with”附近的语法不正确。如果此语句是公共表表达式、xmlnamespaces子句或更改跟踪上下文子句，则前一条语句必须以分号终止

Msg 319，第15级，状态1，第30行
关键字“with”附近的语法不正确。如果此语句是公共表表达式、xmlnamespaces子句或更改跟踪上下文子句，则前一条语句必须以分号终止

这是SQL Server 2016安装

有什么帮助吗？

您的语法有误。带的第一个

与您的索引相关，因此它应该在这之后

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]))

只是语法有点不对劲。使用

将第一个约束移动到绑定到约束的文件组之前

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]))

检查括号。
