Примеры сложных условий запросов к БД в xPDO

Мне довольно часто приходится формировать совсем не простые запросы к БД, и не редко xPDO не позволяет просто так составить нужный запрос. В процессе я нарыл весьма глубинный способ формировать нужные запросы с вложенными подзапросами.  
 
Вот один из таких примеров (который в общих чертах попадет в новую сборку ShopModxBox, которую я так давно обещаю и кто-то уже устал ждать).
 
<?php

require_once MODX_CORE_PATH . 'components/billing/processors/mgr/orders/grid/getlist.class.php';

class ShopOrdersGetlistProcessor extends modMgrOrdersGridGetlistProcessor{
    
    
    public function prepareQueryBeforeCount(xPDOQuery $c){
        $c = parent::prepareQueryBeforeCount($c);
        
        $alias = $c->getAlias();
        
        $where = array();
        
        if($status = (int)$this->getProperty('status')){
            $where['status_id'] = $status;
        }
        
        if($contractor = (int)$this->getProperty('contractor')){
            $where['contractor'] = $contractor;
        }
        
        if($date_from = $this->getProperty('date_from')){
            $where['createdon:>='] = date('Y-m-d H:i:s', strtotime($this->getProperty('date_from')));
        }
        
        if($date_from = $this->getProperty('date_till')){
            $where['createdon:<='] = date('Y-m-d H:i:s', strtotime($this->getProperty('date_till')));
        }
                
        if($where){
            $c->where($where);
        }
        
        
        
        if($search = $this->getProperty('search')){
            $word = $this->modx->quote("%{$search}%");
            
            $q = $this->modx->newQuery('OrderProduct');
            $q->innerJoin('ShopmodxProduct', 'Product');
            $q->innerJoin('modResource', 'ResourceProduct', "ResourceProduct.id = Product.resource_id");
            
            $q_alias = $q->getAlias();
            
            $q->select(array(
                "{$q_alias}.order_id",
            ));
            
            $order_id = (int)$search;
            
            $q->where(array(
                "order_id = {$alias}.id 
                AND (order_id = {$order_id}
                    OR ResourceProduct.pagetitle LIKE {$word} 
                    OR ResourceProduct.longtitle LIKE {$word}
                    OR ResourceProduct.content LIKE {$word}
                )",
            ));
            
            $q->prepare();
            $sql = $q->toSQL();
            
            # print $sql;
            
            $c->where(array(
                "ContractorProfile.phone LIKE {$word}",
            ));
            $c->query['where'][] = new xPDOQueryCondition(array(
                'sql' => "EXISTS ({$sql})",
                'conjunction'   => "OR",
            ));
            
        }
        
        
        return $c;
    }
    
}

return 'ShopOrdersGetlistProcessor';

Советую особое внимание обратить на параметр 'conjunction' => «OR».
 
Этот запрос позволяет выполнить поиск заказов с учетом дат, id заказа, пользователя, заголовков/контента товаров и т.п.
 Вот итоговый SQL:

Другой вариант этого же запроса:
 
<?php

require_once MODX_CORE_PATH . 'components/billing/processors/mgr/orders/grid/getlist.class.php';

class ShopOrdersGetlistProcessor extends modMgrOrdersGridGetlistProcessor{
    
    
    public function prepareQueryBeforeCount(xPDOQuery $c){
        $c = parent::prepareQueryBeforeCount($c);
        
        $alias = $c->getAlias();
        
        $where = array();
        
        if($status = (int)$this->getProperty('status')){
            $where['status_id'] = $status;
        }
        
        if($contractor = (int)$this->getProperty('contractor')){
            $where['contractor'] = $contractor;
        }
        
        if($date_from = $this->getProperty('date_from')){
            $where['createdon:>='] = date('Y-m-d H:i:s', strtotime($this->getProperty('date_from')));
        }
        
        if($date_from = $this->getProperty('date_till')){
            $where['createdon:<='] = date('Y-m-d H:i:s', strtotime($this->getProperty('date_till')));
        }
                
        if($where){
            $c->where($where);
        }
        
        
        
        if($search = $this->getProperty('search')){
            $word = $this->modx->quote("%{$search}%");
            
            $q = $this->modx->newQuery('OrderProduct');
            $q->innerJoin('ShopmodxProduct', 'Product');
            $q->innerJoin('modResource', 'ResourceProduct', "ResourceProduct.id = Product.resource_id");
            
            $q_alias = $q->getAlias();
            
            $q->select(array(
                "{$q_alias}.order_id",
            ));
            
            $order_id = (int)$search;
            
            $q->where(array(
                "order_id = {$alias}.id 
                AND (order_id = {$order_id}
                    OR ResourceProduct.pagetitle LIKE {$word} 
                    OR ResourceProduct.longtitle LIKE {$word}
                    OR ResourceProduct.content LIKE {$word}
                )",
            ));
            
            $q->prepare();
            $sql = $q->toSQL();
            
            $c->query['where'][] = new xPDOQueryCondition(array(
                'sql' => "ContractorProfile.phone LIKE {$word}",
            ));
            $c->query['where'][] = new xPDOQueryCondition(array(
                'sql' => "EXISTS ({$sql})",
                'conjunction'   => "OR",
            ));
        }
        
        
        return $c;
    }
    
}

return 'ShopOrdersGetlistProcessor';

Формирует тот же самый запрос. Отличие только в том, что заменили конструкцию 
$c->where(array(
                "ContractorProfile.phone LIKE {$word}",
            ));
на 
$c->query['where'][] = new xPDOQueryCondition(array(
                'sql' => "ContractorProfile.phone LIKE {$word}",
            ));
Здесь конструкций EXISTS более предпочтительна, чем обычный JOIN, так как у на записи не уникальные (Заказ и Товары заказа — связь один-ко-многим). EXISTS выполняет промежуточный поиск и возвращает по прежнему уникальные записи из основной таблицы. А если джоинить, то получим не уникальные записи.
 
UPD: В предыдущей версии запроса были логические ошибки. Кто скажет какие — молодца! :)
 Исправленная версия запроса с улучшениями:

                $conditions[] = new xPDOQueryCondition(array(
