Hi,
Instead of using php to work out the 30 days part you could just let the
database do it:
$sql = " SELECT DISTINCT restaurants.ID, name, address, inDate
FROM restaurants, inspections
WHERE restaurants.name != '' AND
CAST(inspections.inDate AS DATE) <=
DATE_SUB(NOW(),INTERVAL 30 DAYS)
GROUP BY restaurants.ID ORDER BY 'name' ";
You will have to check that the CAST function is working properly on your
varchar'ed date
fields before testing this query. It should point you in the right direction
though.
Regards
Ian
