Which of these SQL coding styles is better and why?
Comma first:
SELECT Name
, Email
, Phone
FROM Contact
Comma last:
SELECT Name,
Email,
Phone
FROM Contact
Both are valid, do what you or your shop does consistently. I prefer method 2. Visually at first glance the first one appears to be missing a comma, only after you look some more do you notice that its fine. Readability for others is key.
