(Possible) bug in module followup ps1.3.6

[ezakimak]

Hi,

recently we realized that there might be a bug in this module, for instance the reOrder part of the module, it always shows that 0 emails will be processed next time.
Looking at the code of this method followup::reOrder($count)
the sql sentence is wrong

 $emails = Db::getInstance()->ExecuteS('
       SELECT o.id_order, c.id_cart, c.id_lang, cu.id_customer, cu.firstname, cu.lastname, cu.email
       FROM '._DB_PREFIX_.'orders o
       LEFT JOIN '._DB_PREFIX_.'customer cu ON (cu.id_customer = o.id_customer)
       LEFT JOIN '._DB_PREFIX_.'cart c ON (c.id_cart = o.id_cart)
       WHERE o.valid = 1 AND c.date_add >= DATE_SUB(CURDATE(),INTERVAL 7 DAY) AND o.id_order NOT IN 
       (SELECT id_order FROM '._DB_PREFIX_.'log_email WHERE id_email_type = 2)');

the select id_order from ps_log_email where id_email_type = 2 , in ps_log_email there is no id_order column according to the code in method followup:install()

 public function install()
   {
       $logEmailTable = Db::getInstance()->Execute('
       CREATE TABLE '._DB_PREFIX_.'log_email (
       `id_log_email` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
       `id_email_type` INT UNSIGNED NOT NULL ,
       `id_discount` INT UNSIGNED NOT NULL ,
       `id_customer` INT UNSIGNED NULL ,
       `id_cart` INT UNSIGNED NULL ,
       `date_add` DATETIME NOT NULL
       ) ENGINE='._MYSQL_ENGINE_);

       foreach ($this->confKeys AS $key)
           Configuration::updateValue($key, 0);

       Configuration::updateValue('PS_FOLLOWUP_SECURE_KEY', strtoupper(Tools::passwdGen(16)));

       return parent::install();
   }

so, should I change (would it be safe?) the first sql sentence from

 $emails = Db::getInstance()->ExecuteS('
       SELECT o.id_order, c.id_cart, c.id_lang, cu.id_customer, cu.firstname, cu.lastname, cu.email
       FROM '._DB_PREFIX_.'orders o
       LEFT JOIN '._DB_PREFIX_.'customer cu ON (cu.id_customer = o.id_customer)
       LEFT JOIN '._DB_PREFIX_.'cart c ON (c.id_cart = o.id_cart)
       WHERE o.valid = 1 AND c.date_add >= DATE_SUB(CURDATE(),INTERVAL 7 DAY) AND o.id_order NOT IN 
       (SELECT id_order FROM '._DB_PREFIX_.'log_email WHERE id_email_type = 2)');

to

 $emails = Db::getInstance()->ExecuteS('
       SELECT o.id_order, c.id_cart, c.id_lang, cu.id_customer, cu.firstname, cu.lastname, cu.email
       FROM '._DB_PREFIX_.'orders o
       LEFT JOIN '._DB_PREFIX_.'customer cu ON (cu.id_customer = o.id_customer)
       LEFT JOIN '._DB_PREFIX_.'cart c ON (c.id_cart = o.id_cart)
       WHERE o.valid = 1 AND c.date_add >= DATE_SUB(CURDATE(),INTERVAL 7 DAY) AND o.id_cart NOT IN 
       (SELECT id_cart FROM '._DB_PREFIX_.'log_email WHERE id_email_type = 2)');

thanks for any input on this

regards
