缺少「選擇」？

outer apply 
( 
SELECT isnull(
    (select top 1 

     sea.Daily,   
     sea.SeasonId  
    from Season as sea  
    where sea.propertyId = prop.PropertyId and FromDate < @FromDate and ToDate > @ToDate 
    ), 
    (select top 1 sea.Daily,    
     sea.SeasonId    
     from Season as sea where sea.propertyId = prop.PropertyId) 
    )   
) as pri
