询问：

select city.name as name, sum(count) as views from profpostview
inner join professional as prof on prof.pfid = profpostview.viewerpfid
left join cityinfo as city on city.cityid = prof.cityid
where pfpid = _pfpid group by name order by views desc;

输出：

**name , views**

'Ahmedabad', '14'
'Gandhinagar', '7'
'Mumbai', '5'
'Aalborg', '5'
'Rajkot', '3'
'Bhavnagar', '2'
'Baroda', '1'

必需的：

**name, views**

'Ahmedabad', '14'
'Gandhinagar', '7'
'Aalborg', '5'
'others', '11
