Ogg: Re: [Qgis-user] QGIS 2.16 DB Manager and spatialite view

Hello Enrico,QGIS implements an older arrangement from the first version of 
Spatialite. The views share metadata with tables in geometry_columns.I think 
that QGIS should use the proper metadata table as well. It's time to do it as 
Spatialite is at version 4 and the views_geometry_columns comes from version 
2.4 or so. Probably it could handle both metadata for compatibility, after 
enforcing the wrong arrangement for years.Anyhow, to solve your problem, just 
add an entry in geometry_columns.c

Subject: [Qgis-user] QGIS 2.16 DB Manager and spatialite view



Content-Type: text/plain; charset="utf-8"


I have created a database with spatialite_gui tool, the database has some 
spatial views created with a code like this

CREATE VIEW comunitorino AS

SELECT c.ROWID as rowid, c.cod_com, c.geometry

from comuni c;

INSERT INTO views_geometry_columns

    (view_name, view_geometry, view_rowid, f_table_name, 

  VALUES ('comunitorino', 'geometry', 'rowid', 'comuni', 'geometry',1)

The view can be load in QGIS by 'add spatialite layer' button

The problem is that if I use DB Manager and open the DB the view will not be 
seen as spatial view.

If I create the view in DB Manger with the "Create a view" button the view will 
be seen as spatial view.

Where is the mistake?
