You rename a column in MySQL using alter table and change. Let's say our column is currently named soda but you decide that beverage would be a more appropriate title. This column is located on the table called menu. Here is an example of how to change it:
In a more generic fashion, this would be:
alter table menu change soda beverage varchar (10) ;
Also, obviously the varchar (10) can change to be appropriate for your column.
alter table tablename change oldname newname varchar (10) ;
