mySQL语法错误,但没有错误？

Question

它不断收到此SQL错误,但我非常确定查询中没有错误.我一直盯着它看太久了.还有其他可能导致这种情况的事吗？

INSERT INTO game_data (clue, image, answer, wrong, right) VALUES ('asdf',         'asdf', 'asdf', 'assdf', 'asdf')

Invalid Query: 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 'right) VALUES ('asdf', 'asdf', 'asdf', 'assdf', 'asdf')' at line 1

我用这个确切的代码运行其他查询,只是交换变量,它的工作原理.

并且为了更好的衡量,有一个PHP生成这个:

$sql = "INSERT INTO game_data (clue, image, answer, wrong, right) VALUES
    ('" . $clue . "', '" . $image . "', '" . $answer . "', '" . $wrong . "', '" . $right . "')";

Answer 1

right是MYSQL中的保留关键字.你需要使用这样的反引号来逃避它:

INSERT INTO game_data (`clue`, `image`, `answer`, `wrong`, `right`) VALUES

注意:尽量避免将列命名为保留关键字名称.
