However, opening the same table (or an SQL on that table) results in an error 
message about an invalid layer, but no further or useful diagnostic info.
Can anyone suggest a possible cause or solution?


Hi Brent Wood,
I think it would help to find the cause of the issue and it's solution 
if you reported the full error message (and any other error message 
logged in the "Log Messages" panel) and described how exactly you import 
the layer in the QGIS project (and possibly also provided a sample layer 
file affected by the issue).


Best regards.

[Qgis-user] QGIS unable to access Spatialite tables.

[Brent Wood via QGIS-User]

Hi,

I and a few colleagues are encountering a problem accessing Spatialite tables 
from QGIS.
It does not seem to be happening with v3.28, but it is with v3.34 (in both 
Linux & Windows).

When opening a table in v2.8 there are no issues, everything is working as it 
has in recent years.
However, opening the same table (or an SQL on that table) results in an error 
message about an invalid layer, but no further or useful diagnostic info.

Can anyone suggest a possible cause or solution? My current workaround is to 
run the select in the Spatialite command line tool, with the geometry exported 
as WKT & then open the text file in QGIS.

At present I'm still trying to get access to the QGIS issues facility to log 
this problem, so cannot raise this there at present.



Thanks...
