Question

我只打印两个表数据，所以我使用内连接

SELECT  sd.GameName 
FROM LottoryTickets AS sd
    JOIN group AS p 
    ON sd.Group = p.groupname 
WHERE p.groupname = 11

现在我得到了＃106 4 - 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 'group AS p ON sd.Group = p.groupname WHERE p.groupname = 11 LIMIT 0, 30' at line 3

这个回复请指导我

感谢您的进步。

Answer 1

使用：

`group` //as group is a predefined keyword

Answer 2

group是MySQL中的关键字，如果你想用这个名称调用一个表，你必须用反引号括起名字;

SELECT  sd.GameName 
FROM LottoryTickets AS sd
    JOIN `group` AS p 
    ON sd.Group = p.groupname 
WHERE p.groupname = 11

Answer 3

GROUP是ansi sql保留字。 eaven提交的代码很明显（组用蓝色着色）。

TRY

SELECT  sd.GameName 
FROM LottoryTickets AS sd
    JOIN `group` AS p 
    ON sd.Group = p.groupname 
WHERE p.groupname = 11

内联接查询显示错误
