Hi,
I've noticed several times recently that a simple step that seems to speed
up my queries (sometimes quite substantially) is to replace a join like...
... FROM sales INNER JOIN customer ON sales.pk = customer.pk
with this
... FROM sale, customer WHERE sale.pk = customer.pk
I was under the impression that both of these methods were pretty much the
same thing, but apparently not. What is the difference?
Thanks
