Adding a range of dates (Conditional concatenation)

Tue, 10 Sep 2013 11:37:48 GMT

As a result I would like a table with the following fields:

- Date

- Process

- UOM

- Hours

- Volumes

I'm getting two date-fields from text-files: date_from and date_to

I would like to get all dates within this range and add those dates (1-by-1) to my result-Table.

In my Solution I've added a MasterCalendar. So I would need all individual dates in my result-Table.

My script so far:

TempData: // I'm using a TempTable as many more columns are imported from the TextFiles

LOAD date_from,

date_to,

Process,

UOM,

Hours,

Volumes

FROM $(TextFiles);

ActualData:

LOAD date_from as %Date,

date_to - date_from as NumberOfDays,

Process,

UOM,

Hours,

Volumes

RESIDENT TempData;

The ActualData is what I expect it to be.

The column NumberOfDays will be 0 (date_from = date_to) most of the time.

But it is possible that for one Process (eg. Inbound) a date range for the whole week has been set.

In what way can I concatenate only those records to my table [ActualData] where NumberOfDays doesn't equal 0?

You need a loop which generated the additional date-values. This could be done with a while-statement within the load - see the example (was for another case but the logic is the same.

Hi Marcus,

I've just started to use QlikView and QlikCommunity.

Sounds like the example is exactly what I'm looking for, but I can't find it.

Can you tell me how to get to the example?

Thanks in advance

Erik

If you have a licenced version you could simply download the attachment - if not you are depend only on code and explanations here - this is the code from the example:

LET vBeginn = Date('01.01.2014', 'DD.MM.YYYY');
LET vEnde = Date('31.12.2018', 'DD.MM.YYYY');

tmp_Klienten:
LOAD * INLINE [
    Klientennr, Kostenstelle, ZugangDatum, AbgangDatum
    1451, 50115, 01.01.2013, 31.07.2014
    1451, 30228, 01.08.2014, 31.12.2200
    9512, 50115, 01.03.2012, 04.12.2013
    9512, 40168, 05.12.2013, 30.06.2014
    9512, 25997, 21.07.2014, 31.12.2200
    9599, 50115, 01.05.2014, 31.12.2015
    9600, 50115, 15.01.2014, 31.10.2016
    9601, 50115, 01.01.2013, 31.12.2013
];
    
tmp_BELEGUNG2:
LOAD *,
    rowno() as DS,
    Kostenstelle &'-' &Klientennr &'-' &ZugangDatum AS SCHLÜSSEL,
     IF(DATE(ZugangDatum,'YYYYMM') = DATE(AbgangDatum,'YYYYMM'), AbgangDatum - ZugangDatum + 1,
         IF(Iterno() = 1, MONTHSEND(1, ZugangDatum) - ZugangDatum,
             IF(DATE(ADDMONTHS(ZugangDatum, iterno() -1, 1), 'YYYYMM') = DATE(AbgangDatum,'YYYYMM'), DAY(AbgangDatum), // If last Month just take day of DatBis as amount of days
                 DAY(MONTHSEND(1, ADDMONTHS(ZugangDatum, iterno() -1, 1)))))) AS AnzahlTage,
    MonthStart(DATE(ADDMonths(ZugangDatum, iterno() -1, 1), 'MM.YYYY')) AS MonatJahr
RESIDENT tmp_Klienten
WHILE DATE(ADDMONTHS(ZugangDatum, iterno() -1, 1), 'YYYYMM') <= DATE(AbgangDatum,'YYYYMM');
//and MonthStart(DATE(ADDMonths(ZugangDatum, iterno() -1, 1), 'MM.YYYY')) >= DATE(MinDate,'MM.YYYY') --> funktioniert nicht ???
//and MonthStart(DATE(ADDMonths(ZugangDatum, iterno() -1, 1), 'MM.YYYY')) <= DATE('$(vEnde)','MM.YYYY'); --> funktioniert

BELEGUNG:
NoConcatenate LOAD * RESIDENT tmp_BELEGUNG2 WHERE MonatJahr >= '$(vBeginn)' AND MonatJahr <= '$(vEnde)';

DROP TABLES tmp_Klienten, tmp_BELEGUNG2;

Hi Marcus,

Where did you configure the layaout of your table?

I don't have the option "use borders"

Your lay-out:
