I accidentally removed the WHERE clause from my SQL query in a personal tool. Every row is now the same. I overwrote 206,000+ rows. I have no backup, I am stupid. (lemmy.world)

"UPDATE table_name SET w = $1, x = $2, z = $4 WHERE y = $3 RETURNING *",

does not do the same as

"UPDATE table_name SET w = $1, x = $2, y = $3, z = $4 RETURNING *",

It's 2 am and my mind blanked out the WHERE, and just wanted the numbers neatly in order of 1234.

idiot.

FML.

Thanks, I'll look into it! I'm interested in why you got downvoted though! 😅

I didn't downvote but some people like ideologically dislike orms. The reasons I've heard are usually "I can write better SQL by hand", "I don't want to use/learn another library", "it has some limitations"

Those things can be true. Writing better SQL by hand definitely is a big "it depends", though.

I can see why people might dislike them. Adds some bloat perhaps. But at the same time, I like the idea that my input is definitely sanitised since the ORM was written by people who know what they’re doing. That’s not to say it won’t have any vulnerabilities at all, but the chance of them existing is a lot lower than when I write the queries by hand. A lapse of judgement is all it takes. Even more relevant for beginning developers who might not be aware of such vulnerabilities existing.

For a personal tool that runs locally I can handle some bloat in the name of safety!

[–] max@feddit.nl 1 points 1 year ago

Mostly just safety from yourself/your own little errors in input, but it can’t hurt for sure! Input sanitation is mostly relevant to fend off script kiddies. Relevant xkcd
