Transaction (Process ID 60) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction

Hi,

I have the query like

SELECT mp.* 
FROM 
dbo.PropertDetail mp
LEFT JOIN dbo.PeropertyKey mk 
ON mp.KeyID = mk.KeyID
WHERE 
mk.PropertyTime >= (SELECT DATEADD(HH, -2, MAX(PropertyTime)) FROM PropertyKey)
AND error<>0

Error: Transaction (Process ID 60) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction

 When I process this SQL stmt in a ETL package I'm getting the above error.
