Salve.
Ho seguito la discussione un po' al volo, ma mi pare che questa nota aiuti a capire
(se no, scusatemi).
Saluti.

Notice that you have duplicate ROWID values in your view results. Spatialite (and DB
manager) don't care about this since the ROWID is more a convenience. But for QGIS
it's critical that this column be like a unique primary key.
This is happening because you have GROUP BY with two columns in your query. I think
that what will resolve this is creating a new integer column with unique values for
each Fortas-rusis pair.
If you could try this: add to both the siksnosparniai_rusis table and the
siksnosparniai_patalpa tables additional integer columns with unique values for each
Fortas and unique values for each rusis. Then in your view, combine these two
integers in some way to get a new *unique* value to be used as the ROWID. That should
work out the duplicate error values in QGIS.
Good luck,
Micha

Hello,
I have a problem with the display of tables add to QGIS from spatialite.
DB Manager displays the correct data, but uploading to QGIS table entries
changed to false:

When loaded data export to shapfile then show the correct data:

Is this a bug? Is it my fault as a user?
I work with Debian

Sicuramente.
Con i DB occorre fare attenzione alla replicazione degli id. È un mantra da ripetere,
Mai provocare la duplicazipne degli id nelle viste.
