Pranam Guruji 🙏😍

A course can have multiple students enrolled in it. So will it not be more efficient to use the course id as a foreign key in the student table?

how foreign key can accept null and duplicate values....

Can the name of foreign key and primary key be different ??

Please don't request for your channel to get subscribed ... jo nahi kar rahe unka hee loss hai ... ab koi khud apna loss karna chahata hai to .. ham log kya kare 😂😂

you replaced foreign key word with primary key? or I heard wrong

sir as we are using a foreign key while insertion if i inserted roll_number 10 not present in the refernced table but there in referncing table its not showing any error as u prescribed it should an error right?
its happenend when i created a new referencing table and placed the query like this:
roll_number int refernces student(roll_number);

Thanks alot sir for giving us amazing lectures 💕God bless Yuu.. we rr heartily thankful to Yuu.. ❤

Thank you sir ❤
