I have two tables 'Student' and 'Book' created in a SQL databse. 'Student' table consists of 'Roll number(Primary Key), Name' columns and 'Book' table consists of 'Book number(Primary key), Book name, Author name'. How can I join the two tables such that I know which books are issued to which Student.. Actually I will make Student Roll number feed into my program and then check the books issued to that student..
Help required..

Thank You..

Solution 1

The simple answer is :
you need a 3rd table StudentHasBorrowedBook with 2 PKs colums Roll number and Book number.

That said the question might become much more complicated if you have 2 prints of the same 'Book'
