SQL插入相关表

在我看来，这似乎是 SQL/数据库开发中经常出现的问题，但我对这一切都是新手，所以请原谅我的无知。

我有 2 张桌子：

CREATE TABLE [dbo].[Tracks](
    [TrackStringId] [bigint] NOT NULL,
    [Id] [bigint] IDENTITY(1,1) NOT NULL,
    [Time] [datetime] NOT NULL,
 CONSTRAINT [PK_Tracks] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF,
        IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON,
        ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[Tracks] CHECK CONSTRAINT [FK_Tracks_AudioStreams]
GO

ALTER TABLE [dbo].[Tracks]  WITH CHECK ADD  CONSTRAINT
[FK_Tracks_TrackStrings]     FOREIGN KEY([TrackStringId])
REFERENCES [dbo].[TrackStrings] ([Id])
GO

ALTER TABLE [dbo].[Tracks] CHECK CONSTRAINT [FK_Tracks_TrackStrings]
GO

and

CREATE TABLE [dbo].[TrackStrings](
    [Id] [bigint] IDENTITY(1,1) NOT NULL,
    [String] [nvarchar](512) NOT NULL,
 CONSTRAINT [PK_Strings] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF,
        IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON,
        ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

我想在轨道表中插入一个新条目。这还涉及在 trackstrings 表中插入一个新条目，并确保曲目中的外键列 trackstringid 指向 trackstring 中的新条目。实现这一目标最有效的方法是什么？

首先，插入TrackStrings，从列列表中省略主键列。这调用了它的IDENTITY自动生成值的列。

INSERT INTO [dbo].[TrackStrings] ([String]) 
  VALUES ('some string');

其次，插入Tracks并指定为它的TrackStringId功能SCOPE_IDENTITY() http://msdn.microsoft.com/en-us/library/ms190315(SQL.90).aspx，它返回由IDENTITY column 在你当前的范围内.

INSERT INTO [dbo].[Tracks] ([TrackStringId], [Time]) 
  VALUES (SCOPE_IDENTITY(), CURRENT_TIMESTAMP());
