Zend DB fetchAll(): where as array

I'm confused as to why Zend_DB doesn't accept an array of WHERE clauses - or am I incorrect? I have made the following work around:

$all = new ORM_Model_DbTable_Asset();
$wheres = array('id > 0', 'enabled' => 1);
$all = $all->fetchAll(implode(' AND ', $wheres))->toArray();

for what I hoped would be:

$all = new ORM_Model_DbTable_Asset();
$wheres = array('id > 0', 'enabled' => 1);
$all = $all->fetchAll($wheres)->toArray();

Slightly disappointing, am I missing something?

From Zend_Db_Table_Abstract

/**
 * Fetches all rows.
 *
 * Honors the Zend_Db_Adapter fetch mode.
 *
 * @param string|array|Zend_Db_Table_Select $where  OPTIONAL An SQL WHERE clause or Zend_Db_Table_Select object.
 * @param string|array                      $order  OPTIONAL An SQL ORDER clause.
 * @param int                               $count  OPTIONAL An SQL LIMIT count.
 * @param int                               $offset OPTIONAL An SQL LIMIT offset.
 * @return Zend_Db_Table_Rowset_Abstract The row results per the Zend_Db_Adapter fetch mode.
 */
public function fetchAll($where = null, $order = null, $count = null, $offset = null)

So you are incorrect, fetchAll() does accept an array of where clauses.

Your array should look like this (based on the definition in Zend_Db_Select)

$where = array(
    'id > 0',
    'enabled = ?' => 1
);
