SQL INNER JOIN的多个表错误

Question

SQL：

SELECT * FROM `orderregel` 
INNER JOIN `klant` ON order.KlantId = klant.KlantId 
INNER JOIN `product` ON orderregel.ProductId = product.ProductId 
INNER JOIN `order` ON orderregel.OrderId = order.OrderId; 

ERROR: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order., orderregel., product., klant. FROM orderregel INNER JOIN klant O' at line 1

我的数据库：订单（订单ID，客户ID（FC）），行项目（OrderregelId，订单ID（FK），产品编号（FK），客户ID（ FC）），顾客（客户ID，姓名，名字），产品（产品编号，名称）

我想从谁拥有自己的顺序为每个行项目显示product.Naam，klant.Naam

Answer 1

这条线：

INNER JOIN `klant` ON order.KlantId = klant.KlantId 

还需要勾选保留MySQL是order

INNER JOIN `klant` ON `order`.KlantId = klant.KlantId 

• https://dev.mysql.com/doc/refman/5.5/en/keywords.html

注意其中的错误开始，告诉你：

right syntax to use near 'order

的同样的事情：

INNER JOIN `order` ON orderregel.OrderId = order.OrderId; 

到

INNER JOIN `order` ON orderregel.OrderId = `order`.OrderId; 

重写：

SELECT * FROM `orderregel` 
INNER JOIN `klant` ON `order`.KlantId = klant.KlantId 
INNER JOIN `product` ON orderregel.ProductId = product.ProductId 
INNER JOIN `order` ON orderregel.OrderId = `order`.OrderId; 

编辑：按OP的评论，但与各地的MySQL蜱order保留。

SELECT * FROM orderregel 
INNER JOIN klant ON orderregel.KlantId = klant.KlantId 
INNER JOIN product ON orderregel.ProductId = product.ProductId 
INNER JOIN `order` ON orderregel.OrderId = `order`.OrderId; 

Answer 2

内的快速重新排序加入语句可能帮助（未测试）

SELECT * FROM `orderregel` 
INNER JOIN `klant` ON orderregel.KlantId = klant.KlantId 
INNER JOIN `product` ON orderregel.ProductId = product.ProductId 
INNER JOIN `order` ON order.OrderId = order.OrderId;
