hi we had a similar issue in that we could not find a way of saving join information. The technique we ended up using was to extend the qml syntax to support join field definitions, and use a small function to re-establish joins correctly. This is really useful if the same sets of tables are used in multiple projects. Its simply a matter of loading the qml files using the layer -> properties -> load style function.
We also use it as an easy method to define the join fields within other applications such as Augview. It means that UI behaviour within multiple applications is consistent and only needs defining once. hope that is helpful. If you want to use the same syntax, let me know & i will send some documentation. regards *Mike Bundock* | CEO Augview | P O Box 125046, St Heliers, Auckland 1740, New Zealand p: +64 9 575 5298 | m: +64 27 575 5298 | e: mailto:[email protected] <[email protected]>| w: www.augview.net Winner of Innovation & Commercialisation and Supreme Awards at 2014 NZ Spatial Excellence Awards Winner of Innovation & Commercialisation Award at 2014 Asia Pacific Spatial Excellence Awards On Fri, 17 Oct 2025, 11:13 pm Simon Dietmann via QGIS-User, < [email protected]> wrote: > Dear list, > > > > I am trying to export some feature classes inside a common gpkg that have > attribute joins to a table that’s also stored in the same gpkg.
