Linking Dates issue

Thu, 16 Apr 2015 11:06:17 GMT

Hello people, I've read some topics about linking dates. Now I want to do something more 'advanced'. I obtained a Qlikview example of the basics. It looks like this:

In order to create the Link table, this script is used:

Link:

LOAD

,CreatedDate as Date

,'Created' as DateType

RESIDENT Table1

;

CONCATENATE (Link)

LOAD

,DepartureDate as Date

,'Departure' as DateType

RESIDENT Table2

;

CONCATENATE (Link)

LOAD

OtherID

,OtherDate as Date

,'Other' as DateType

RESIDENT OtherTable

;

Okay from here all fine! Now I want to something like this:

Is it possible to make the Link table obtain the DepartureDate from Table3, since it is now not directly connected? If so how would I script that?

Help is much appreciated!

I suppose that you have to use a 2 way calculation

Tmp:

noconcatenate

load *

resident Table2;

left join(Tmp)

load *

resident Table3;

Link:

left join(Link)

ID,

DepartureDate as LinKDepartureDate

resdient Tmp;

drop table Tmp;

Rename of DepartureDate is necessary to avoid syntetic keys

you drop TABLE3 (as there is no further information if there is nothing else in there)

Hi thx for the input,

I see what you are trying to do with the Tmp table, however when applying the part under Link I will get an extra field in the Link table, LinkDeparture. Basically what Im trying to achieve is that the link table should get the same output with different table setups.

The picture below shows the content of the Link Table, the right one is how it should be. The left one is with the other table setup.

I can get the Departure values in it, but not related to the ID numbers..

When I say:

CONCATENATE (Link)

LOAD

RESIDENT Table2

It will of course just add 3 lines with the ID numbers, but not related to the DepartureDate..

(Ive attached the qvws if that is helpful for anyone)
