[Qgis-user] Help opening a Spatialite view in QGIS

[Brent Wood]

Hi,

I have created a view in a spatialite database, but am unable to open it in QGIS.

I can't find any documentation on how this works.

I have a table "stations" which contains a station_no column (integer) and a point geometry column (startp, EPSG 4326).

The view is created by:
create view v_stat as select station_no, startp from station;


I add an entry to the Spatialite views_geometry_columns table to populate the metadata describing the view.
insert into views_geometry_columns
        (view_name, view_geometry, view_rowid, f_table_name, f_geometry_column, read_only)
      values
        ('v_stat', 'startp', 'station_no', 'station', 'startp', 1)

QGIS now lists the view correctly as a table with a geometry & lists startp as the geometry, but when I try to open it, I just get an "invalid layer" error message.

 dbname='/home/baw/tan2413/tan2413.spdb' table="v_stat" (startp) is an invalid layer - not loaded


Can anyone tell me how to set up a Spatialite view so it can be successfully opened in QGIS?


Thanks
