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

Try using INSERT IGNORE instead of INSERT where INSERT IGNORE will not insert a new row if a duplicate primary key is found. This should help resolve the problem temporary but I would recommend truncating the table.

Answer 2

The problem is that the name of a foreign key can not be the same as another foreign key in the entire model.

Imagine this situation

Catalog --> Supplier

Product --> Supplier

if the name of the foreign key in table Catalog for supplier is "supplier" and you assigned the same name in product table then the foreign keys names will "collide".

You need to name them differently..

For example:

catalog_supplier product_supplier

Answer 3

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