Re: Solution to retrieve first and last row for each minute

Its really slow but what you can do is something like the following:

select count(a.*), b.* from foo.bar a,
(
select price from foo.bar order by time asc limit 1
union 
select price from foo.bar order by time desc limit 1
) as b
group by b.price
... just do the "wheres" as you need  ...

PS its untested maybe there are some syntax miss-spells
