Hi Brent,
I think you are correct. PostGis could be a way to go. I was thinking
more like using python and geopandas rather than PostGis. I will look
PostGis more carefully. I just posted this in case I was missing some
major innovation or plugin in QGIS. I normally work with csv, shp or
single layer Geopackages so I has wondering if I was missing something
obvious. Nothing more frustrating than coding something that is already
done.
Thanks for the input

Umm,
A bit left fieldish, but is that sort of thing something that Postgis
is perhaps more suited to than QGIS?
Could you not ogr the geopackage into Postgis & script up the work you
want doing?
It sounds like what you want to do is very much in the arena of data
management.

*Subject:* [Qgis-user] batch operation on gpkg with multiple layers
Hi,
Before I go to my default mode and python my way through this, is
there a plugin that would permit me to perform batch operation on all
the layers found in a single .gpkg file? My geopackages contain
hundreds of layers (from autocad) (contain identical data structures)
and I would like to do things like:
* Perform field calculator operations on each layer within the
geopackage
* Split all geopackage layer with a field
* Merge multiple layers in a new geopackage
I guess FME would be another way out? I there an OpenSource equivilant
to this? (I have a home version but I need to respect the license for
this one.)
