SELECT COUNT(DISTINCT(ccc)) AS ccc,COUNT(DISTINCT(bbb)) AS bbb FROM total WHERE user_id='$user_id' AND ADDDATE BETWEEN '$time[starttime]' AND '$endtime' GROUP BY aaa ORDER BY aaa DESC
The sql statement is as above, can anyone give me some advice?

考虑使用MongoDB的aggregation:
1、COUNT(DISTINCT(ccc)) AS ccc,COUNT(DISTINCT(bbb)) AS bbb
$group+$sum
2、user_id='$user_id' AND ADDDATE BETWEEN '$time[starttime]' AND '$endtime'
$match
供参考。
Love MongoDB!Have fun!
