MySQL error 1022 when creating table

Question

MySQL Workbench came up with the following SQL to create a table:

CREATE  TABLE IF NOT EXISTS `mydb`.`errors_reports` (
   `error_id` INT NOT NULL ,
   `repo         


        

Answer 1

It seems you're creating an index on the foreign key columns. When creating a foreign key in InnoDb, one will be created automatically.
