I got incredible results in asking AIs for sql functions. I just enter my data and what I want the output to look like. Then I ask it to provide 10 different versions that might be faster. I test them all and tell it which is faster and then I ask it to make variations on this path. Then I ask it to add comments to the code which is the fastest. I verify the query, do some more test, and I'm good to go. I understand SQL pretty well but trying to make 10 different versions of one code would've took me at least an hour.
