Zend DB fetchAll(): where as array - zend-framework

Question

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?

Answer 1

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
);

Answer 2

First we will look at your original code:
$wheres = array('id > 0', 'enabled' => 1);
Remember that => is an assignment operator. In your array above you start out with string automatically assigned to key 0. The next element is the number 1 assigned to the key 'enabled'. The solution proposed in answer 1 assigns the number 1 to key 'enabled = ?'.
Try this:
$all = new ORM_Model_DbTable_Asset();
$where = array();
$where[] = 'id > 0';
$where[] = $all->quote_into('enabled >= ?', 1, 'INTEGER'); // 1 could be a variable
$result = $all->fetchAll($where);
