致命错误:带有消息'SQLSTATE [42000]的未捕获异常'PDOException':语法错误或访问冲突:1064 SQL语法中有错误;检查与您的MySQL服务器版本相对应的手册,以便在C:\ xampp \ htdocs \ PhpProject1 \ userv2.php的第1行''附近使用正确的语法')120堆栈跟踪:#0 C: \ xampp \ htdocs \ PhpProject1 \ userv2.php(120):PDOStatement-> execute()#1 C:\ xampp \ htdocs \ PhpProject1 \ create.php(41):User-> Save()#2 {main在第120行的C:\ xampp \ htdocs \ PhpProject1 \ userv2.php中抛出

我们使用了返回tick作为列名称,因为它在这里的一些帖子中建议但它并没有完全解决错误。我读了类似的帖子,但找不到解决方案,所以我正在为你的帮助提供错误和代码。提前谢谢。

MySQL INSERT的正确语法是:

INSERT INTO tbl_name (col1,col2,col3) VALUES(15,col1*2,'string');

而不是:

INSERT INTO "tbl_name" ("col1","col2","col3") VALUES(15,col1*2,'string');
