mysql中两列的总和

Question

我正在制作水晶报告，我正在制作基于效果的报告。这是我的查询

select mguser.userID, mguser.userName as Loger,date_format(trschedule.insDate,'%Y-%m-%d') as _Date,
count(distinct trschedule.scheduleID) as Schedule_Count, count(*) segment_count
FROM
mguser

我希望将这两列的总和--- count（distinct trschedule.scheduleID）作为Schedule_Count，count（*）segment_count

我怎样才能在mysql ???
