have you tried:

No, I hadn't tried that, but it didn't work.  It still wants to treat the second argument as a column name.

After a bit of debugging to see what query was actually being generated I discovered that this was the right track, but only part of the answer.

My original attempt:

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

Results in a query like this:

  SELECT `table_z`.*,`table_z`.`Some Value` AS `col_d` FROM `table_z` ...  

Using the Zend_Db_Expr approach to the same query:

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

results in:

  SELECT `table_z`.*,Some Value AS `col_d` FROM `table_z` ...  

Which is really close.  The other half turns out to be quote():

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

results in:

  SELECT `table_z`.*,'Some Value' AS `col_d` FROM `table_z` ... 

There has to be a better way, but this at least works.
