MySQL双等号 [英] MySQL Double Equal Sign

问题描述

我正在调试一个旧网站，但出现一些SQL错误. 当我检查它时，发现了以下查询.

I'm debugging an old website, and I get some SQL errors. When I went through it, I found the following query.

UPDATE boats
set    new_high_date == DATE_ADD(NOW(), INTERVAL 3 MONTH)
WHERE  id=49701

我不知道 == 是什么意思.这是有效的查询吗? 我似乎无法执行它.

I don't know what the == here means. Is this a valid query? I cannot seem to execute it.

我不确定是否应该更改它，或者这意味着什么?

I'm not sure if I should change this, or does it mean something?

推荐答案

MySQL中没有double相等，因此应将其删除.

There is no double equal in MySQL so you should remove it.
