Last updated: http://alvinalexander.com/blog/post/mysql/mysql-error-1005-hy000 June 3 2016 I got the following MySQL error ("1005 error") earlier today when trying to create a table with a foreign key relationship: ERROR 1005 (HY000): Can't create table './mover/mover_files.frm' (errno: 150) In my case this MySQL ERROR 1005 (HY000) error came from having slightly different declarations for the index of one table, error 1005 which was referenced as a foreign key in my second table. When I created the index on the first table I declared it as id int unsigned auto_increment not null, and when I created the foreign key I declared it as file_source_id int not null, accidentally omitting the unsigned keyword. I solved the problem error 1005 (hy000) by simply adding the unsigned keyword to my second field definition, as that's how I really want it. MySQL was right, I did have an error in my foreign key relationship, but the error message "ERROR 1005 (HY000): Can't create table" just wasn't very helpful. A few more details Here's a little more information on the two declarations that led to this MySQL error message ... in the first table, named file_sources, I declared my id field like this: id int unsigned auto_increment not null And in the table where I created the foreign key I had these two declarations: file_source_id int not null, constraint foreign key fk_mover_files_to_file_sources (file_source_id) references file_sources(id) As mentioned, you'll see that I declared the auto_increment field using the unsigned keyword, but I didn't use that keyword when defining the file_source_id field. It's a subtle error, but an error nonetheless. mysql mysql error 1005 error Solving the MySQL "can't create/write to file" error message mysqldump e
