This seems like it ought to be straightforward:

from osgeo import gdal
gpkg = gdal.OpenEx('path_to_gpk',gdal.OF_VERBOSE_ERROR,allowed_drivers=['GPKG'])
error = gpkg.DeleteLayer(0)

After running this error is always a OGRERR_FAILURE. The geopackage has been created by QGIS so I would have thought should be standard.

Can't see any way to debug further into the GDAL calls apart from a GDB session, which I might try later.


Simple indeed....

Proper code below:

from osgeo import gdal
gpkg = gdal.OpenEx('path_to_gpk',gdal.OF_OF_UPDATE,allowed_drivers=['GPKG'])
error = gpkg.DeleteLayer(0)
# this code is also possible as an alternative
# doesn't seem to delete everything though, so possibly DeleteLayer() is better
# gpkg.ExecuteSQL('DROP TABLE [layer name]')

Note that you will have to refresh any connections (e.g. in QGIS) manually and there is no refresh button as of 3.10.

  • What remains after DROP TABLE? It certainly works when it is used as -sql parameter with ogrinfo.
