求大神指导下，是那些方面出问题了？js大部分代码如下：
var tablename = ‘MTC_CDMA_1X_’+dbn+’_’+act;
var table = db.getCollection(tablename);
var outc = ‘CDMA_1X_’+dbn+’_’+act+’_agkb’;

table.aggregate([{$match:{“I”:{$gte:kaishi,$lt:jieshu}}},
{$match:{“Y131”:{$exists:true}}},
{$project:{“Y64″:1,”Y7″:1,”Y1″:1,”Y61.M0″:1,”Y32″:1,”Y99″:1,”Y256″:1,”Y131″:1,”Y201″:1,”Y311″:1,”Y71″:1,”Y502″:1,”Y92″:1,”Y93″:1,”Y109″:1,”Y117″:1,”Y529″:1}},
{$group:{_id:{sdate:”$Y64″,szone:”$Y7″,uid:”$Y1″,phone:”$Y61.M0″,utype:”$Y32″,ptype:”$Y99″,sid:”$Y256″,pid:”$Y131″,did:”$Y201″,pjx:”$Y311″,dtype:”$Y71″,rtype:”$Y502″},uv:{$sum:”$Y92″},dv:{$sum:”$Y93″},tv:{$sum:”$Y109″},tt:{$sum:”$Y117″},tf:{$sum:”$Y529”}}},
{$out:outc}],
