[gdal-dev] GIS Stack Exchange questions - delete geopackage layer

[jratike80]

Hi,

Actually this is the official GDAL support channel so no need to be sorry.

While I am sure that DeleteLayer works when used correctly there is also
another option to execute SQL “DROP TABLE layer_name” as documented in
https://gdal.org/drivers/vector/gpkg.html.
