Anyone know if there's any possible difference between listing the tables and using a where clause to attach them, or using an inner join? (See below.)
select * from order_header, order_line
where order_header.order_no = order_line.order_no
and order_header.order_no = 100001
select * from order_header
inner join order_line on order_header.order_no = order_line.order_no
where order_header.order_no = 100001
