It's possible to order alphabetically all columns in tables of a mysql db?
I would like to order all columns in all tables 


The order of column [names] within a Table should not matter. 

Every "select" statement that goes anywhere near your database should explicitly specify the columns that it wants, in the order that it wants them.  How the actual table is arranged matters not a jot.  

If you have lots of columns with similar names, this may be indicative of a larger problem.
