Re: ERROR 1005: Can't create table (errno: 121) Help

Hi!

errno 121 means a duplicate key error. Probably the table already exists in the InnoDB internal data dictionary, though the .frm file for the table has been deleted. This is the most common reason for getting errno 121 in table creation. Another possible reason is a name conflict in a foreign key constraint name. Constraint names must be unique in a database, like table names are.

What does InnoDB print in the .err log?

Best regards,

Heikki
