怎样从数据库中读取时间C

select a.cpsn_num as 人员编码,b.vschool as 毕业学校

from hr_hi_person a

left join

(

select *, row_number() over(partition by cpsn_num order by dgrduateDate desc) as rowNum from hr_hi_edu

)b

on a.cpsn_num =b.cpsn_num and b.rowNum=1

你好，是你啊，呵呵。SetTime不能接受COleDateTime作为参数，SetTime的定义如下：int SetTime(int nHour, int nMin, int nSec)从定义可知，SetTime只接受三个整形参数，即小时、分、秒。 COleDateTime类重载了=号，你可以通过等号设置时间，你可以这样写：m_starttime=COleDateTime(varValue[2].m_pdate->year,varValue[2].m_pdate->month,varValue[2].m_pdate->day,0,0,0)
