Hello

2012/4/6 Andreas<maps...@gmx.net>:
hi,

is there a disadvantage to write a join as

select   *
from    a, b
where  a.id = b.a_id;


over

select   *
from    a join b  on  a.id = b.a_id;


yes - newer notation has some advantages

* clean specification join predicate and filter predicate
* simple adaptability to outer join
* increased protection against copy/paste bug that introduce Cartesian product
