I have 2 tables:
book ( id, title, age ) ---- 100 milions of rows
author ( id, book_id, name, born ) ---- 10 millions of rows
Now, supposing I have a generic id of a book. I need to print this page:
Title: mybook
authors: Tom, Graham, Luis, Clarke, George
So... what is the best way to do this ?
1) Simple join like this:
Select book.title, author.name
From book, author
WHERE ( author.book_id = book.id ) AND ( book.id = 342 )
2) For avoid the join, I could make 2 simple query:
Select title FROM book WHERE id = 342
Select name FROM author WHERE book_id = 342
What is the most efficient way ?
