Convert *= / =* to outer joins (ANSI compliant)I'm working on converting *= and =* to 'left outer join' and 'right outer join'. I noticed the difference in behavior between the =* and the phrase "right outer join" and between *= and 'left outer join'. The result set is different. Here is an example: select a.au_id, b.title, c.qty from titleauthor a, titles b, sales c where (a.title_id =* b.title_id) and (a.title_id =* c.title_id) I try to conver the above to: select a.au_id, b.title, c.qty from titleauthor a right outer join titles b on (a.title_id = b.title_id ) right outer join sales c on (a.title_id = c.title_id ) The first results into 391 rows in pubs database of sql-server 2000 and the second produces 34 rows. It seems not that straight forward to convert. The question is: If I want to get 391 row, what should I change/add in the second sql statement? Thank you. Appreciate your help. Joan |
