There are some tables that we want to do a search.
I couldn’t understand why this error happens , please help.
I should be easy for experts,

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

the Error :

Msg 4104, Level 16, State 1, Line 1
The multi-part identifier ‘ppp.passenger-id’ could not be bound.

Tables are :

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

Second

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

Third

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])

If I had problem in setting the relations , please tell me how to do ,

thanks

Edited Part

Thanks , I found that in parallel with you , but I got another error : ( In my real code I want to get Passenger-id , but it doesn’t allow me )

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

The Error is:

Msg 209, Level 16, State 1, Procedure SearchForPassenger, Line 19
Ambiguous column name ‘passenger-id’.

It refers to the 1st line that we want to select [passenger-id]

  1. The problem is a missing alias ppp

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