[Qgis-user] Selecting records

[Phil (The Geek) Wyatt]

I must be thick, but I can't get my head around this in QGIS

 

Data


stationid_

obs_date


BK21

28/03/2016


BK21

29/03/2016


BK21

30/03/2016


BL22

28/03/2016


BL22

29/03/2016


BL22

30/03/2016


BL22

31/03/2016

 

 

How do I select the Maximum date for each station ID?

 

The data will be coming from a GEOJSON feed but I can also pull it as a
shape file if needs be

 

 

Cheers - Phil
