MySQLi INSERT语法错误

Question

I get this error in my PHP script:

Notice: 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 'like, dislike) VALUES (?, ?, ?, ?)' at line 1[`NSERT INTO workouts_likes_by_user (id_from_wall, user_name, like, dislike) VALUES (?, ?, ?, ?)] in /hermes/bosoraweb110/b720/ipg.workoutlogappcom/android_connect/update_likes.php5 on line 50

This is my query:

$sql = "INSERT INTO workouts_likes_by_user (id_from_wall, user_name, like, 
dislike) VALUES (?, ?, ?, ?)";

Thanks.

Answer 1

LIKE is a reserved keyword . If you want to use it in your query, wrap them in backticks like so:

$sql = "INSERT INTO workouts_likes_by_user 
(id_from_wall, user_name, `like`, dislike) 
VALUES (?, ?, ?, ?)";

Of course, not using reserved keywords in your query is the best way, but escaping them using backticks works, too.
