Question

In a Zend_Db_Select object, I am doing a join to get user information for some data records. For the join is on a userId, I would like to combine the user first and last name into a single column of name.

Basically I am looking to have something similar to this:

$table = array('u' => 'User');
$condition = 'u.id = t.id';
$columns = array('UserName' => 'u.FirstName + " " + u.LastName')
$select->joinLeft($table, $condition, $columns);

I have tried using a Zend_Db_Expr with no luck and the above does not work.

How would I go about doing this?

Zend_Db_Expr is the way to go, but you’ll have better luck if you use the database’s concatenation function. Assuming MySQL:

$columns = new Zend_Db_Expr("CONCAT(u.FirstName, ' ', u.LastName') AS name")
