Thanks for your reply Rudy,
may I ask why I could get into trouble using the "comma list" style in the JOINs?
It seems way more readable to me and it is coherent with the SELECT statement.

Is it performance you are concerned about?
Has it something to do with the MySQL engine, I often use a DB Type of InnoDB?

Your positioning of the commas in the SELECT statement makes alot of sense, I will adopt it.
