[Qgis-user] QGIS/spatialite issue - invalid layers

[Brent Wood]

Hi,

I have created an empty spatialite database with QGIS via the browser.

Running Mint Linux with QGIS:

3.34.1-Prizren

QGIS code revision

133927424d9<https://github.com/qgis/QGIS/commit/133927424d9>



I create a spatialite table (in spatialite) & add some point data (EPSG 4326 - column is called "geom"). This opens fine in QGIS.

I add another geometry column to the table (point, epsg:3994)  & populate it with:
  update station set geom_3994= transform(geom,3994);

This appears fine in spatialite, but QGIS tells me it is an invalid layer, but nothing about why...

I have been doing this sort of stuff for years & not encountered this before.

Can anyone help me sort out why QGIS regards the data as invalid, & how to fix this?


Thanks
