Custom SWQL Query Resource Help

I'm working with EOC trying to use the Custom SWQL query resources to get a resource to show me all Acknowledged alerts from Orion servers.  The following works in SQL:

Select

EOC_AlertStatus.ObjectName, EOC_AlertStatus.TriggerTimeStamp,

EOC_AlertDefinition.Name, EOC_AlertStatus.Acknowledged,

EOC_AlertStatus.AcknowledgedTime, EOC_AlertStatus.AcknowledgedBy

From EOC_AlertStatus

Join EOC_AlertDefinition on EOC_AlertStatus.AlertDefID = EOC_AlertDefinition.AlertDefID

Where EOC_AlertStatus.Acknowledged = 1

But if I try to use it following the SWQL documentation I've found, trying to run it this way:

SELECT

EOC.AlertStatus.ObjectName, EOC.AlertStatus.TriggerTimeStamp,

EOC.AlertDefinition.Name, EOC.AlertStatus.Acknowledged,

EOC.AlertStatus.AcknowledgedTime, EOC.AlertStatus.AcknowledgedBy

FROM EOC.AlertStatus

INNER JOIN EOC.AlertDefinition on EOC.AlertStatus.AlertDefID = EOC.AlertDefinition.AlertDefID

WHERE EOC.AlertStatus.Acknowledged = 1

results in the resource being unable to process the request.  Anyone thoughts?
