Best way to use INNER JOIN?
Date: Sun, 1 Jun 2008 17:58:38 +0100
Using Oracle 10g
I've always used this form of inner joins -
- select BOOKSHELF.Title from BOOKSHELF, BOOK_ORDER where BOOKSHELF.Title = BOOK_ORDER.Title;
A colleague tells me that I should be using this form (but can't tell me why?) -
2. select Title from BOOKSHELF inner join BOOK_ORDER using (Title);
There is another way I've seen (but don't like) -
3. select Title from BOOKSHELF natural inner join BOOK_ORDER;
So, is there any difference between methods 1 and 2? if not is it safe to continue using method 1 then?
thanks in advance
