Shows SQL for columns ALTER TABLE ... [ADD|DROP] COLUMN combines a selection of multiple columns into a single alter table. Show collation in list of columns. (order of columns isn't what is should be but that should maybe be fixed by a generic column selection and ordering mechanism that knows what the default sort should be)
