I stopped surprising at MySQL syntax eons ago, so if that works... great!
Otherwise I would write the equivalent statement with a more "standard
syntax" (for whatever meaning of "standard" in the SQL world :-) as:
UPDATE visitors
SET visitors.hits=visitors.hits+1,
visitors.useros=%s,
visitors.browser=%s,
visitors.date=%s
WHERE visitors.pin=(SELECT counters.pin
FROM counters
WHERE counters.page=%s)
AND visitors.host=%s
But I wonder about the "logic" here: why are you storing the "useros",
"browser" and "date" in a table where the primary key seems to be
("pin", "host")? I mean, what happens if a user visits the same page
twice, first with Firefox and then with Chrome?
hope this helps,
ciao, lele.
