Surely this is something that can be done easily with an SQL Select with
Order-by, in one of the SQL variants that QGIS can use?
I’m asking for my own benefit too. Having come from the MapInfo environment I
would reach for an SQL Select to do this task, but I’m less familiar with SQL
in QGIS.

In this particular instance the data are not spatial data, at this stage at
least. There is no link to location.
The data does have a hierarchy according to several columns, by sorting I can
put the data into a suitable order for editing in further information into an
extra column. Without

Thanks, can you suggest how as the refactor fields help is not clear, to say
the least, about saving after sorting.
I sorted the data (5 million rows) by a couple of the columns, just by clicking
on them, then wanted to save in the new order but this 'save in the new order'
seems impossible.
Hello Michael,
How did you sort the columns? If you have ordered them in the QGIS attribute
table, they will not change their order when you export them. For this, you
must use the "Refactor Fields" tool.
Cheers,
Matti

Good morning,
I have a PostgreSQL database of several million points with
latitude/longitude and I would like to do the following with qgis-server or
PostGis:
according to a number of shapes (hexagons, circles or squares) per mesh,
calculate the number of points per shape and color the shape
What is your question Sylvain?
This is unclear
Regards
