i completed postgresql recently, i don't know how to practice and where to implement?
You can use pgadmin tool to practice postgresql and solve the sql questions in our video for practice.
Can we use where year(publicationyear) = Adddate(curdate(), interval -1, year) in the where condition?Please correct me if am wrong
Why didn't you take a.author id= b.book id?
