Question

Being a bit dim this morning have this query

$result = $DBH->query("SELECT MAX(date_start) as date_start, rates.rate as rate FROM rates WHERE unitID=$ID AND rates.date_start <= $start ");

which only half works by that I mean I always get the max date but rates.rate does not update, to explain more, I need the data from rates.rate based on the value of MAX(date_start)

Sorry if not clear

Answer 1

SELECT date_start,
       rate
FROM   rates
WHERE  unitid = ?
       AND date_start <= ?
ORDER  BY date_start DESC
LIMIT  1
