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?
