为什么我在SQL中遇到多部分标识符错误？

Question

我们想要搜索一些表.
我无法理解为什么会发生这种错误,请帮忙.
对于专家我应该很容易

SELECT * FROM passenger
INNER JOIN [passenger-flylist] ppff 
ON ppp.[passenger-id] = ppff.[passenger-id]

错误 :

消息4104,级别16,状态1,行1
无法绑定多部分标识符"ppp.passenger-id".

表是:

CREATE TABLE [dbo].[passenger](
    [passenger-id] [int] IDENTITY(1,1) NOT NULL,
    [name] [char](50) COLLATE Arabic_CI_AS NOT NULL,
    [sex] [char](10) COLLATE Arabic_CI_AS NULL,
    [mobile] [char](20) COLLATE Arabic_CI_AS NULL,
    [address] [varchar](50) COLLATE Arabic_CI_AS NULL,
    [flylist-id] [int] NOT NULL,
    [chair-number] [char](10) COLLATE Arabic_CI_AS NOT NULL,
    [Age] [char](10) COLLATE Arabic_CI_AS NULL,
    [ticket-number] [char](10) COLLATE Arabic_CI_AS NULL,
 CONSTRAINT [PK_passenger] PRIMARY KEY CLUSTERED 
(
    [passenger-id] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

GO

第二

CREATE TABLE [dbo].[flylist](
    [flylist-id] [int] IDENTITY(1,1) NOT NULL,
    [fly-number] [varchar](50) COLLATE Arabic_CI_AS NOT NULL,
    [go-date] [char](15) COLLATE Arabic_CI_AS NOT NULL,
    [return-date] [char](15) COLLATE Arabic_CI_AS NOT NULL,
    [go-time] [char](5) COLLATE Arabic_CI_AS NOT NULL,
    [return-time] [char](5) COLLATE Arabic_CI_AS NOT NULL,
    [start-from] [varchar](50) COLLATE Arabic_CI_AS NOT NULL,
    [destination] [varchar](50) COLLATE Arabic_CI_AS NULL,
    [airline-company-id] [int] NOT NULL,
    [airplane-id] [int] NOT NULL,
 CONSTRAINT [PK_flylist] PRIMARY KEY CLUSTERED 
(
    [flylist-id] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

GO

第三

CREATE TABLE [dbo].[passenger-flylist](
    [passenger-id] [int] NOT NULL,
    [flylist-id] [int] NOT NULL,
 CONSTRAINT [PK_passenger-flylist] PRIMARY KEY CLUSTERED 
(
    [passenger-id] ASC,
    [flylist-id] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

GO
USE [AirlineSx]
GO
ALTER TABLE [dbo].[passenger-flylist]  WITH CHECK ADD  CONSTRAINT [FK_passenger-flylist_passenger-flylist] FOREIGN KEY([passenger-id], [flylist-id])
REFERENCES [dbo].[passenger-flylist] ([passenger-id], [flylist-id])

如果我在设置关系方面遇到问题,请告诉我该怎么做,

谢谢

编辑部分

谢谢,我发现与你并行,但我得到了另一个错误:(在我的真实代码中,我想获得Passenger-id,但它不允许我)

SELECT [passenger-id] FROM passenger ppp -- <<<< This line
INNER JOIN [passenger-flylist] ppff 
ON ppp.[passenger-id] = ppff.[passenger-id]
INNER JOIN flylist fff ON ppff.[flylist-id] = fff.[flylist-id]
WHERE ppp.[name] = @name AND
fff.[start-from] = @flightDate AND
ppp.[ticket-number] = @ticketNo

错误是:

消息209,级别16,状态1,过程SearchForPassenger,第19行
不明确的列名称'passenger-id'.

它指的是我们要选择的第一行[passenger-id]

Answer 1

问题是缺少别名ppp

SELECT * FROM passenger ppp
INNER JOIN [passenger-flylist] ppff 
ON ppp.[passenger-id] = ppff.[passenger-id]
