Comment:

 The same problem makes it impossible to open a RasterLite db with more
 than one raster layer, see:
 https://trac.osgeo.org/gdal/ticket/3568

 For instance, this: http://www.gaia-gis.it/planet_earth.sqlite fails:
 /home/paolo/Desktop/planet_earth.sqlite is not a supported raster data
 source This raster file has no bands and is invalid as a raster layer.
 Gdal can read it:

 So this is a QGIS limitation : it cannot handle images with subdatasets.
