Question

我正在使用SQL Server 2008 Express R2和高级服务。我是训练中的DBA，所以我在学习，因为我更多地接触SQL。我有一个Base表需要拆分为Header和Details表。这两个表将通过HeaderID链接。标题将有一条记录，详细信息最多可包含64条名称/值记录，与标题表中的一条记录相关联。我需要一个Query来将Base表中的数据复制到Header和Details表中。这是设计：

基准表：

CREATE TABLE [dbo].[tblBase](
[ID] [int] IDENTITY(1,1) NOT NULL,
[PartType] [varchar](50) NULL,
[SerialNumber] [varchar](50) NOT NULL,
[Station] [varchar](50) NULL,

) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,     ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

标题表：

CREATE TABLE [dbo].[tblHeader](
[HeaderID] [bigint] IDENTITY(1,1) NOT NULL,
[SerialNumber] [varchar](50) NOT NULL,
[PartType] [varchar](50) NULL,
[Station] [varchar](50) NULL,
[Reject] [varchar](50) NULL,
[Generation] [varchar](50) NULL,
CONSTRAINT [IX_tblLancoHeader] UNIQUE NONCLUSTERED 
(
    [SerialNumber] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,  ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

详情表：

CREATE TABLE [dbo].[tblLDetail](
[DetailID] [bigint] IDENTITY(1,1) NOT NULL,
[HeaderID] [bigint] NOT NULL,
[Name] [varchar](100) NOT NULL,
[Value] [varchar](100) NULL
) ON [PRIMARY]

希望这很清楚，以便我可以帮助编写查询以将数据从Base表中复制到Header＆amp;详情表。

谢谢，

岩

INSERT  tblHeader (
    [SerialNumber], [PartType], [Station], [Reject], [Generation]
)
SELECT  [PartType], [SerialNumber], [Station], [Reject], [Generation]
FROM    tblBase;

INSERT tblDetail (
    [HeaderID], [Name], [VALUE]
)
SELECT  h.HeaderID, 'Mod_25_1_Orifice', b.Mod_25_1_Orifice
FROM    tblBase b
        JOIN tblHeader h ON b.[SerialNumber] = h.[SerialNumber];

INSERT tblDetail (
    [HeaderID], [Name], [VALUE]
)
SELECT  h.HeaderID, 'Mod_25_1_LowerBody', b.Mod_25_1_LowerBody
FROM    tblBase b
        JOIN tblHeader h ON b.[SerialNumber] = h.[SerialNumber];

etc ...对其他62个细节列插入tblDetail 62次

将SQL Server表拆分为Header和Details表，通过HeaderID链接
