I started using upper case, because I was just trying to match what SQL Server https://en.wikipedia.org/wiki/Microsoft_SQL_Server gives me whenever I tried to create something, like a new stored procedure https://en.wikipedia.org/wiki/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?
