MySQL: Can't create table (errno: 150)

Question

I am trying to import a .sql file and its failing on creating tables.

Here\'s the query that fails:

CREATE TABLE `data` (
`id` int(10) unsigned NOT NUL         


        

Answer 1

usually, the mismatch between foreign key & primary key causes the error:150.

The foreign key must have the same datatype as the primary key. Also, if the primary key is unsigned then the foreign key must also be unsigned.
