How to count days on road with different dimensions

[#1]

Hi,

please have a look at attached QV doc. I need to be able obtain the number of tripdays by selecting for example two months (see example) and not by using the 'LINK' field.

Available datamodel is one that gives me an ugly solution. I know there should be a much more sofisticated and simple answer to this issue. Please help.

DATA:
LOAD Transport,
Date(Date) as Date,
MonthStart(Date) as CalendarMonthStart,
QuarterStart(Date) as CalendarQuarterStart,
YearStart(Date) as CalendarYearStart,
MonthEnd(Date) as CalendarMonthEnd,
QuarterEnd(Date) as CalendarQuarterEnd,
YearEnd(Date) as CalendarYearEnd,
Month(Date) as Month,
Year(Date) as TRIPYEAR,
Year,
Trip,
Transport&Year&Trip as Link
FROM TRIPLEDGER);

join LOAD Transport&Year&Trip as Link,
Enddate,
Startdate,
num(Floor(Enddate-Startdate)+2) as Tripdays
FROM table is dates);

left join (DATA) INTERVALMATCH (Date)
LOAD DISTINCT Startdate, Enddate
RESIDENT [DATA];

join (DATA) load
Link,
if(year(Enddate)>Year(Startdate), (1+num(Floor(Enddate-CalendarYearStart))),Tripdays) as Tripdays2,
if(Year(Enddate)>=Year(Date), '1', '0') as FLAGTripdays
Resident [DATA];

Thanks in advance,

Sjoerd

I don't know quite what you want. Maybe this?

sum(aggr(if(month(Enddate)>month(max(CalendarMonthStart))
,num(floor(CalendarMonthEnd-Startdate)+1), Tripdays2)*FLAGTripdays,Link,Startdate,Enddate))
