php - SQL 更新增量不起作用

Question

我的 SQL 代码有一个小问题：

UPDATE articles SET like=like+1 WHERE id=1

当我试图在 PhpMyAdmin 中执行它时，我收到了这个错误：

#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 'like=like+1 WHERE id=1' at line 1

像 int 的列默认设置为 0（长度为 11）。有谁知道我该如何修复它？请帮忙。

Answer 1

LIKE is a keyword and cannot be used as a column name. You could change it (in your query) to `like`=`like`+1 (with backticks), but that's hardly solving the problem.

Rename your column.

Answer 2

引用您的字段名称：

UPDATE `articles` SET `like` = `like`+1 WHERE `id` = 1;

Answer 3

您将字段“like”设置为与Sql的关键字LIKE相同，因此出现错误。只需更改字段的名称。
