aggregation option for virtual joins

☐ cool new feature
☐ could help many users!

☐ removes a „bug“

☑ nice to have

☐ nobody needs it

other wishes submitted by  hogi_2-1702196401638.png

 

The idea:

if there is no unique identifier for virtual join -- add the possibility to define an aggregation to generate unique values.

 

  • no need to have a unique identifier for virtual joins anymore
  • a default option for data aggregation ["median" would be cool, but just works for numbers; so the not so useful "N"?]
    + a possibility to define the aggregation individually for each column (like in the query builder)

the benefit:

  • the aggregation option makes the virtual join much more versatile
  • the virtual join is almost as "dynamic" as the link functionality of summary table (<->  Query Builder)
  • virtual links survive after the data is saved and re-opened (<-> link table)

the disadvantage:

the aggregation will slow down the virtal join.

 

the woraround:

  • aggregation via summary table
  • join via virtual link
  • important: save as a script
    (to establish the dynamic link again after it got lost after saving the file)

@Sarah-Sylvestre 

this functionality could help a lot to improve the usability of virtual joins.
(I admit: definitely not at the same speed that we enjoy without aggregation)
