Question

我有一张预订表（用户填写表格以申请预订）。

它有两个部分需要确认。 isReservationAccepted（拒绝，接受，等待）和hasReservationBeenSent（发送，拒绝，等待）

不确定如何构建我的表，考虑为每列创建一个查找表，或者只是将它们创建为int，并且1 =接受/发送，2 =拒绝，3 =等待。

我应该如何为这些条件创建状态表？

以下是您可以使用的通用结构：

/****** Object:  Table [dbo].[LookUpTypes]    Script Date: 12/06/2013 10:13:51 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[LookUpTypes](
    [LookUpTypeID] [uniqueidentifier] NOT NULL,
    [LookUpTypeDescription] [varchar](50) NULL,
 CONSTRAINT [PK_LookUpTypes] PRIMARY KEY CLUSTERED 
(
    [LookUpTypeID] 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

SET ANSI_PADDING OFF
GO
--************************************************
CREATE TABLE [dbo].[LookUpValues](
    [LookUpValueID] [uniqueidentifier] NOT NULL,
    [LookUpTypeID] [uniqueidentifier] NOT NULL,
    [LookUpValue] [varchar](50) NOT NULL,
    [LookUpValueDescription] [varchar](255) NULL,
 CONSTRAINT [PK_LookUpValues] PRIMARY KEY CLUSTERED 
(
    [LookUpValueID] 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

SET ANSI_PADDING OFF
GO

ALTER TABLE [dbo].[LookUpValues]  WITH CHECK ADD  CONSTRAINT [FK_LookUpValues_LookUpTypes] FOREIGN KEY([LookUpTypeID])
REFERENCES [dbo].[LookUpTypes] ([LookUpTypeID])
GO

ALTER TABLE [dbo].[LookUpValues] CHECK CONSTRAINT [FK_LookUpValues_LookUpTypes]
GO

为表保存两种略有不同的状态
