         Else
            SELECT userid FROM tracking_lecturas WHERE campaign_id = v_campaign_id and userid = v_userid into ReadBefore;
         end if;

         if ReadBefore is Null then
            insert into tracking_lecturas (campaign_id, ares_emails_id, userid, ip, useragent, timestamp) values (v_campaign_id, v_ares_emails_id, v_userid, v_ip, v_useragent, v_time);
        end if;

试试这个：

-- Dumping structure for procedure test.realiza_tracking_primer_lectura
DROP PROCEDURE IF EXISTS `realiza_tracking_primer_lectura`;
DELIMITER //
CREATE PROCEDURE `realiza_tracking_primer_lectura`(IN `v_campaign_id` int(11),IN `v_ares_emails_id` int(11),IN `v_userid` int(11),IN `v_country` varchar(2),IN `v_ip` varchar(15),IN `v_useragent` varchar(255),IN `v_time` int(11))
BEGIN
    #Routine body goes here...
        DECLARE ReadBefore int DEFAULT null;
        if v_campaign_id is Null then
            SELECT userid FROM tracking_lecturas WHERE ares_emails_id = v_ares_emails_id and userid = v_userid into ReadBefore;
         Else
            SELECT userid FROM tracking_lecturas WHERE campaign_id = v_campaign_id and userid = v_userid into ReadBefore;
         end if;

         if ReadBefore is Null then
            insert into tracking_lecturas (campaign_id, ares_emails_id, userid, ip, useragent, timestamp) values (v_campaign_id, v_ares_emails_id, v_userid, v_ip, v_useragent, v_time);
        end if;

END//
DELIMITER ;
