MYSQL用两个列连接一个并获取数据

Question

修复！抱歉浪费任何时间：P

  

我试图在PHP中使用mysql加入两个colums

$result = $link->query('SELECT Software.*, 
Genre.Naam AS Genre, 
Console.Naam AS ConsoleNaam,
Draager.Naam AS MediumNaam,
Studio.Naam AS StudioNaam,
Publisher.Naam AS PublisherNaam
FROM Software
INNER JOIN Genre ON Genre.Genre_ID = Software.Genre_ID
INNER JOIN Console ON Console.Console_ID = Software.Console_ID
INNER JOIN Draager ON Draager.Draager_ID = Software.Medium_ID
INNER JOIN Company AS Studio ON Software.Studio_ID = Studio.Company_ID
INNER JOIN Company AS Publisher ON Software.Publisher_ID = Publisher.Company_ID
');

     

Table Company必须加入Table Software才能获得ID   公司名称。

     

有关我必须更改为上述脚本以获取内容的任何提示   工作？

Answer 1

你有一个错字。 JOIN拼写错误为JION：

$result = $link->query('SELECT Software.*, 
Genre.Naam AS Genre, 
Console.Naam AS ConsoleNaam,
Draager.Naam AS MediumNaam,
Studio.Naam AS StudioNaam,
Publisher.Naam AS PublisherNaam
FROM Software
INNER JOIN Genre ON Genre.Genre_ID = Software.Genre_ID
INNER JOIN Console ON Console.Console_ID = Software.Console_ID
INNER JOIN Draager ON Draager.Draager_ID = Software.Medium_ID
/* Misspelled JOIN below *(/
INNER JOIN Company AS Studio ON Software.Studio_ID = Studio.Company_ID
INNER JOIN Company AS Publisher ON Software.Publisher_ID = Publisher.Company_ID
');

Answer 2

得到答案：

JION在关联表时拼写为JOIN：D

$result = $link->query('SELECT Software.*, 
Genre.Naam AS Genre, 
Console.Naam AS ConsoleNaam,
Draager.Naam AS MediumNaam,
Studio.Naam AS StudioNaam,
Publisher.Naam AS PublisherNaam
FROM Software
INNER JOIN Genre ON Genre.Genre_ID = Software.Genre_ID
INNER JOIN Console ON Console.Console_ID = Software.Console_ID
INNER JOIN Draager ON Draager.Draager_ID = Software.Medium_ID
INNER JOIN Company AS Studio ON Software.Studio_ID = Studio.Company_ID
INNER JOIN Company AS Publisher ON Software.Publisher_ID = Publisher.Company_ID
');
