Why can't Doctrine retrieve my model data?

So, I'm trying to use Doctrine to retrieve some data. I have some basic code like this:

$conn = Doctrine_Manager::connection(CONNECTION_STRING);
$site = Doctrine_Core::getTable('Site')->find('00024');
echo $site->SiteName;

However, this keeps throwing a SQL error that 'column siteid does not exist'. When I look at the exception the SQL query is this (you can see the error is that the inner_tbl alias for siteid is set to s__siteid, so querying inner_tabl.siteid is what's broken):

SELECT TOP 1 
    [inner_tbl].[siteid] AS [s__siteid]
FROM 
 开发者_开发知识库   (SELECT TOP 1 
        [s].[siteid] AS [s__siteid],
        [s].[name] AS [s__name], 
        [s].[address] AS [s__address], 
        [s].[city] AS [s__city], 
        [s].[zip] AS [s__zip], 
        [s].[state] AS [s__state], 
        [s].[region] AS [s__region], 
        [s].[callprocessor] AS [s__callprocessor], 
        [s].[active] AS [s__active], [s].[dateadded] AS [s__dateadded] 
    FROM [Sites] [s] 
    WHERE ([s].[siteid] = '00024')
    ) AS [inner_tbl] 

Why is the query being generated this way? Could it be the way the Yaml schema is laid out?

I spoke to one of the developers (Johnathan Wage) in the IRC room and he says that SQL may work, but that there are probably bugs (I'm assuming this is one). He also said that Doctrine was written specifically with MySQL in mind.
