you getting sql error because have not quoted values.you can use below code. 

$columns = array('product_id' ,'product_ean', 'product_price', 'name_es-es', 'short_description_es-es'); $values = array(null, $product_ean, $product_price, $name_es, $short_description_es);   // prepare insert query. $query    ->insert($db->quotename($table))    ->columns($db->quotename($columns))    ->values(implode(',', $db->quote($values)));
