How can I select the greatest number from table columns, exp. that is my table:
id|name|views|
1|test|42|
2|test1|89|
3|test2|4|
4|test3|35|
I need to select all values for row id 2, because views is most greatest number from other views? I try this, but don't work:
$q = $this->select()->from($this->_name, array(new Zend_Db_Expr('MAX(views)'), 'id', 'name'))->order('name DESC')->limit(1)->group('name');
return $this->fetchRow($q);

Try...
$q = $this->select()
->from($this->_name, array('id', 'name'))
->order('views DESC')
->limit(1);
return $this->fetchRow($q);
Hint:
Apply ORDER BY views DESC, and then LIMIT 1
