Let’s say have something like:

SELECT energy_produced, energy_consumed, timestamp1 AS timestamp FROM ( SELECT max(energy_produced) AS energy_produced, mid(timestamp, 1, 10) AS timestamp1 FROM tbl_energy WHERE site_id = 1366 AND mid(timestamp, 1, 10) >= DATE_SUB(curdate(),INTERVAL 1 day) group by mid(timestamp1, 1, 10)) AS e1 INNER JOIN ( SELECT max(energy_consumed) AS energy_consumed, mid(timestamp, 1, 10) AS timestamp2 FROM tbl_energy WHERE site_id = 1366 AND mid(timestamp, 1, 10) >= DATE_SUB(curdate(),INTERVAL 1 day) group by mid(timestamp2, 1, 10)) AS e2 ON e1.timestamp1 = e2.timestamp2

Can I just stuff it in a variable and call the sucker like $db->fetchAll($select)->toArray?

  1. Yes, you can pass a SQL statement as a string to the $db->fetchAll() method.

    You don’t need to call toArray() on the result, because the result is already returned as an array by default.

    The Zend_Db_Table class also has a fetchAll() method, but it doesn’t take a SQL string, and it returns a Zend_Db_Table_Rowset object.
