select inq.objid as inquiryinfoid,
count(*),
wmsys.wm_concat(o.fundname) as fundnames
from otc_inquiryinfo inq,
otc_inquiryintention inqt,
otc_fund o,
otc_stockinfo stock
where stock.objid = inq.stockid
and inq.objid = inqt.inquiryinfoid
and inqt.fundkey = o.objid
group by inq.objid,stock.date
order by stock.date;
按照inq.objid进行group by时，同一分组的date一样吗？不一样的话怎么排序
