Don't do this. ORDER is a Reserved Keyword in MySQL.
You should seriously consider naming it to something else, eg: orders, or orderdata
Still, if you want to use order only, then you will have to use backticks around it, like below:
CREATE TABLE `order` (....
or (in your case):
RENAME TABLE ordering TO `order`
