The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.

Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

I'm a tech interested guy. I've touched SQL once or twice, but wasn't able to really make sense of it. That combined with not having a practical use leaves SQL as largely a black box in my mind (though I am somewhat familiar with technical concepts in databasing).
With that, I keep seeing [pic related] as proof that Elon Musk doesn't understand SQL.
Can someone give me a technical explanation for how one would come to that conclusion? I'd love if you could pass technical documentation for that.
As a data engineer for the past 20+ years: There is absolutely no fucking way that the us gov doesnt use sql. This is what shows that he’s stupid not only in sql but in data science in general.
Regarding duplications: its more nuanced than those statements each side put. There can be duplications in certain situations. In some situations there shouldnt be. And I dont really see how duplications in a db is open to fraud.
Yeah, obviously ol' boy is tripping if he thinks SQL isn't used in the government.
Big thing I'm prying at is whether there would be a legitimate purpose to have duplicated SSNs in the database (thus showing the First Bro doesn't understand how SQL works).
It doesn't matter without scope. Are we looking at a database of SSNs? tax records? A sign in log? The social security number database might require uniques in some way, but tax records could be the same person over multiple years. A sign in gives a unique identifier but you could be signing in every day.
It's like saying a car VIN shows up multiple times in a database. Where? What database? Was it sold? Tickets? Registered every year?
This is nothing more than a "assume I mean immigrants or tax fraud and get mad!" inflammatory statement with no proof or reason.
