BACPAC 导入和临时表可能存在 BUG

Question

我正在使用最新版本的 SQL Server 2016 Developer Edition 和 SSMS (13.0.15600.2)。

导入数据层应用程序 (bacpac) 时可能存在错误，该应用程序包含任何时态表和使用 'WITH SCHEMABINDING' 引用它们的任何对象（函数。视图）。

完全可以将此类数据库导出到 backpac，但在将其导回时出现错误：

Error SQL72014: .Net SqlClient Data Provider: Msg 3729, Level 16, State 4, Line 1 Cannot ALTER 'Table2Version' because it is being referenced by object 'BindTest'. Error SQL72045: Script execution error. The executed script: ALTER TABLE [dbo].[Table2Version] SET (SYSTEM_VERSIONING = OFF);

将重现此问题的最小数据库创建脚本是：

USE [master]
 GO


CREATE DATABASE [temptest]
 GO


ALTER DATABASE [temptest] SET COMPATIBILITY_LEVEL = 130
 GO


USE [temptest]
 GO


CREATE SCHEMA [History]
 GO


CREATE TABLE [History].[Table2Version](
  [Id] [int] NOT NULL,
  [Name] [nvarchar](50) NULL,
  [SysStartTime] [datetime2](0) NOT NULL,
  [SysEndTime] [datetime2](0) NOT NULL
 ) ON [PRIMARY]


GO


CREATE CLUSTERED INDEX [ix_Table2Version] ON [History].[Table2Version]
 ([SysEndTime] ASC, [SysStartTime] ASC )
 GO


SET ANSI_NULLS ON
 GO
 SET QUOTED_IDENTIFIER ON
 GO
 CREATE TABLE [dbo].[Table2Version](
  [Id] [int] NOT NULL,
  [Name] [nvarchar](50) NULL,
  [SysStartTime] [datetime2](0) GENERATED ALWAYS AS ROW START HIDDEN NOT NULL,
  [SysEndTime] [datetime2](0) GENERATED ALWAYS AS ROW END HIDDEN NOT NULL,
  CONSTRAINT [PK__Table2Version] PRIMARY KEY NONCLUSTERED ( [Id] ASC ),
  PERIOD FOR SYSTEM_TIME ([SysStartTime], [SysEndTime])
 ) ON [PRIMARY]
 WITH ( SYSTEM_VERSIONING = ON (HISTORY_TABLE = [History].[Table2Version] , DATA_CONSISTENCY_CHECK = ON ))


GO


CREATE FUNCTION [dbo].[BindTest]()   
 RETURNS TABLE   
 WITH SCHEMABINDING    
 AS    
 RETURN SELECT Id AS id
 from dbo.Table2Version  ;  



GO

真的是bug还是我做错了什么？
