Hi William, fellow BC'er here.
One thing you can do is change the default behaviour, like instead of
loading all features, try loading only features visible on map (or selected
features).
Can change that in Settings > Options then the Data Source tab. You'll see
an "attribute table behavior" pull

Is the attribute table failing to load or simply taking a very long time
to load?
I use some old shapefiles with around 500,000 rows, they are very slow
loading, it just takes a time, I think is probably the same for a lot of
large datasets, but it doesn't have trouble drawing the layers on th
Hi users.
I am looking for some best practice tips for working with datasets with many
rows. Using QGIS 3.4.4 Our organization regularly works with large oracle
database tables covering a large geographic region(eg 2 M+ rows, 1 + Gb). QGIS
seems to draw these layers fine but chokes on them whe
Hi Jose,
it was possible in QGIS v2.x with the plugin AutoFields [1]. Now in QGIS
3.x some devs have partially implemented the AutoFields functionalities
into QGIS core, but your use case is still not supported.
However, a project in Colombia [2] is funding exactly that use case. It
could land in
Thanks for your suggestion but Unfortunately, I'm a beginner with python or

Hi everybody,
I'm trying to generate an automatic field, I mean, a field that depends for
two others. We have FIELD1, FIELD2 and SUM. The result should be SUM =
FIELD1 + FIELD2. The thing is, if I change the value of FIELD1, the value
of SUM should change. Example: FIELD1 (8) + FIELD2 (10) = SUM (
