I've done a bunch of searching on the Internet and in the e-mail archives and can't find the answer to this.  How do you model a query like this using Zend_Db_Select?

SELECT col_a, col_b, col_c, 'Some Value' AS col_d
  FROM table_z

or event SELECT *, 'Some Value' AS col_d ...

I've tried code like this in a Zend_Db_Table class:

  $select = $this->select();   $select->from($this->name, array('*', 'col_d' => '"Some Value"'));  

and several variations including escaping the quotes.  Is this even possible?  If not, any suggestions for a workaround?

TIA!
