I have a table one of whose columns is named 'interval', which is also
a mysql datatype. I don't know how easy it is to create such a table,
but it sure isn't easy to use it.

Mysql won't let me access this column in any way that I've tried: I
can't select it or update it; I can't delete it or rename it.
Do I have to recreate the whole table to get rid of it?

thanks, --thelma

Use backticks to access it:
ALTER tablename CHANGE COLUMN `interval` other_name <rest of column
definition>

Quote it with back-tickies, like `interval` and think every time how
annoying it is, and resolve never to permit this kind of foolishness to
happen in the future.

Thank you, and thanks also to Rik Wasmus.
I didn't create the table; I just inherited it, but it's kept
me from adding columns called 'limits' and 'done', names
too close to things the database might someday want for itself
