    The irony.. i learned all this..
    but i still can't think of being told how to actually… fill the tables.
    I must've missed it…
    kind of hilarious really.

    MySQL workbench is not allowing me to use the field products(product_id) as a foreign key in two separate tables. Is this a restriction inherent to SQL?

    An example of a situation where you'd want to remove a foreign key is if you're refactoring your application, and want to drop the table which contained a column which was referenced in the foreign key.

    Hey Quentin, how's it going? I was just wondering if you are able to make some more vlogs of Johannesburg, it is completely understandable if you are not able to, but I would like to see some more, please. And also, are you going to be making an angular series?
