very helpful, lectures

What a stupid explanation. Clearly she doesn't have any experience

mam y don't you explain about the syntaxes for writing the keys

the first line you say that each table should definitely have a primary key, but never explained why. Could have explained why it is compulsory to have a primary key with a real world example.

Very helpful and to the point for my semester exams. Thank you mam!
