Is there a good reason to use upper case for SQL keywords? [closed]

The default seems to be upper case, but is there really any reason to use upper case for keywords?

I started using upper case, because I was just trying to match what SQL Server gives me whenever I tried to create something, like a new stored procedure. But then, I felt terrible for my baby (5th) finger, that always needs to hold down the Shift button, so I stopped using upper case. Is there a reason why I should go back to upper case?

Answer

It’s just a matter of style, probably originating in the days when editors didn’t do code colouring.

I used to prefer all upper case, but I’m now leaning towards all lower.

Either way, be consistent.
