Comment on How does this pic show that Elon Musk doesnt know SQL?
DacoTaco@lemmy.world 2 weeks agoSsn being unique isnt a dump idea, its a very smart idea, but due to the us ssn format its impossible to do. Hence to implement the idea you need to change the ssn format so it is unique before then.
Also, elons remark is stupid as is. Im sure the row has a unique id, even if its just a rowid column.

even then, i wonder if there’s some sort of “row has function” that takes a hash of all the data in a single entry, and generates a universally unique hash of that entry, as a form of “global id”
