Zend Framework Select Objects And UNION()

Question

I\'m pretty sure this is not possible in Zend Framework (I have searched the Web, the documentation and issue tracker) but I just want to make sure so I\'m asking here.

Answer 1

Here's what I've done to make a union:

$select = $this->select();
//common select from both sides of the union goes here

$select1 = clone($select);
//select1 specifics here

$select2 = clone($select);
//select 2 specifics here

$db = $this->getAdapter();
$pageselect = $db->select()->union(array("($select1)", "($select2)"));

Remember Db_Select's __toString will print out the SQL generated by that select, to help you debug.
