SQL根据同一个工号，不同的打卡记录，合并时间，以及打了多少次筛选出记录

select a.FRegNo,a.FDate,a.FTime,a.num from(select
FRegNo,
FDate=CONVERT(varchar(100), FDate, 23),
FTime=STUFF((select ‘,’+rtrim(CONVERT(varchar(100), FTime, 8))
from #temp where st.FRegNo=FRegNo and FDate=‘2017-05-12’ order by FTime for XML path(’’)),1,1,’’),
COUNT(1) as num
from #temp st group by FRegNo,FDate ) a where a.FDate=‘2017-05-12’ Order by a.FRegNo
