I have 3 tables that are 1:1 and will always have a row for a given
product,_code & date. If I want to join them together, is it going to be
faster to use an equi join or a left join, or does it matter?
Who cares, they are -different- things symantically, use the correct type of
join for your data and resultset. "Speed" is an implementation issue, a
physical property.
