Question

I have following MYSQL syntax but when I am running it , it gives me error to check the MYSQL manual for correct syntax.

The MYSQL query is:

SELECT `listings`.sid FROM listings 
        LEFT JOIN `listings_properties` `lp` ON `lp`.`object_sid` = `listings`.`sid` AND `lp`.`id` = \'ClosingDate\'
        WHERE (expiration_date < NOW() OR `lp`.`value` <= NOW()) AND active = 1

Answer 1

SELECT a.`sid` FROM `listings` a LEFT JOIN `listings_properties` b 
ON (b.`object_sid` = a.`sid` AND b.`id` = 'ClosingDate')
WHERE (a.`expiration_date` < NOW() OR b.`value` <= NOW()) AND a.`active` = 1

No need to escape '
