Custom Query SWQL | Alerts with ACK and Alerts without ACK

hello folks, it's been a couple of days I try to migrate a query that succeeds in report writer to a Custom Query view. My idea is to create a view for my NOC that has on the left a  query to find all the alarm without ACK and right all alarms with ACK. I was watching that alarms without seeing are dated 1899.

Query from RR

SELECT

AlertStatus.ObjectName as Node, AlertStatus.TriggerTimeStamp as Date, AlertStatus.TriggerTimeStamp as Time,AlertDefinitions.AlertName

FROM AlertStatus, AlertDefinitions

WHERE AlertDefinitions.AlertDefId=AlertStatus.AlertDefId AND AlertStatus.ObjectName like '%mpls%'

or AlertDefinitions.AlertDefId=AlertStatus.AlertDefId AND AlertStatus.ObjectName like '%bgp%' AND AlertStatus.AcknowledgedTime not like '%1899%'

ORDER BY AlertStatus.TriggerTimeStamp DES

I was reading SWQL http://knowledgebase.solarwinds.com/kb/questions/4543/__print but still fails to become good friends.

Thanks in advance.
