Count(if(aggr)) counts only the first value. Why?

Sat, 20 Dec 2014 02:06:03 GMT

I've got 2 tables:

t1:
Load CID,TID,date(Tdate,'DD.MM.YYYY')as TDATE Inline
[
  CID,TID,Tdate
  1,1,25.12.2014
  1,2,20.05.2014
  2,3,14.03.2015
  1,4,28.10.2015
];
t2:
Load CID,EID,date(Edate,'DD.MM.YYYY')as EDATE Inline
[
  CID,EID,Edate
  1,9,18.05.2014
  1,7,16.05.2014
  1,1,21.05.2014
  1,2,19.05.2014
  2,3,20.05.2014
  1,4,29.11.2015
  1,5,26.05.2014
  1,6,15.04.2014
  1,8,17.06.2014
];

and a straight table chart with a dimension CID and expression

Count(if(aggr(min(TDATE),CID)>EDATE, EID))

The count shows values = 1 for both CIDs, inspite that there are several (4) EIDs for CID=1 that suit the condition. I found out that the Count finds only the first suitable EDATE in the table, but for all others the condition is false. What's wrong?

Hi,

Try this

Count(If(Aggr(NODISTINCT Min(TDATE),CID)>Aggr(Only(EDATE),CID,EID),EID))

Re: Count(if(aggr)) counts only the first value. Why?

=SUM(IF(Date(Aggr(Only(EDATE),EID,CID)) <=Aggr(NODISTINCT Min(TDATE),CID),1,0))

Actually, in my case, adding nodistinct to aggr in initial expression solved the problem. So it became

Count(if(aggr(nodistinct min(TDATE),CID)>EDATE, EID))

But the real data model appears to be much more complicated and the trick doesn't work well. So I'll try to adapt it to my solution. If fail, I'll come back for more assistance. Anyway, thank you, guys!
