How do I change my table in sql database after creating it?

You need drop foreign key in another table/tables, which references to STUDENT table.How do I change my table in sql database after creating it?
You will need to ';break'; the relationship betwen the tables (remove the foreign keys) so the table stands on its own. Then delete it or amend it then recreate the relation
