How not null and primary key can be set on the same column as primary key = not null + unique key ? I checked it is possible but technically it should not work in that way
A is correct because it have valid order of statements:
DEFAULT ____ NOT NULL
From this reason C is not valid because it have
NOT NULL DEFAULT _____ which is wrong order.
B and E are not valid because the are mentioning other columns
in default statement.
nvm, column cannot be a default value in next column.
