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.
Take this with a grain of salt as I’m not a dev, but do work on CMS reporting for a health information tech company. Depending on how the database is designed an SSN could appear in multiple tables.
In my experience reduplication happens as part of generating a report so that all relevant data related to a key and scope of the report can be gathered from the various tables.
A given SSN appearing in multiple tables actually makes sense. To someone not familiar with SQL (i.e. at about my level of understanding), I could see that being misinterpreted as having multiple SSN repeated “in the database”.
Of all the comments ao far, I find yours the most compelling.
