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)
