i have two where-clauses:
a) ... WHERE company=1 and product=7
b) ... WHERE product=7 and company=1
with other words the position of the where fields are swapped.
now the question is:
bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???
in my point of view, there is a parser/optimizer who cares about this, so i don't have to care about.
