CREATE TABLE `movies`.`movie`

#1089 - Incorrect prefix key; the used key part isn't a string, the used length is longer than the key part, or the storage engine doesn't
support unique prefix keys.
With the part
PRIMARY KEY (`movie_id`(3))
you are telling mysql to create a sub part key* on the first 3 letters of movie id. This only works for string types.
You need to use
PRIMARY KEY (`movie_id`)
without providing a length.
*Is this sure the query resulting in the error? Never saw that on a primary key, its used for indexes.
