Description
I've created a virtual layer to calculate the building coverage ratio of land parcels. Unfortunately, selecting features with two or more parts seems not to work properly in QGIS 2.14.3 (see screencast).

[virtual] disable FilterRect when no unique id is present. Should fix #15134

I confirm this problem occurs not only with multi-part features but with single-part features as well.
See http://gis.stackexchange.com/a/218328/4972 for a reproducible example with single points (airports) with Natural Earth Shapefiles as Virtual Layer's source.
I've tested this on QGIS v2.14.8 (GNU/Linux), QGIS 2.16.3 (Windows 7), and a recent (from October, 2016) QGIS build v2.99 (GNU/Linux).
Sorry for setting priority to high, it's just that, in my opinion, this issue might make Virtual Layers unusable in a production environment.

Hi gcarrillo,
selecting features seems to work properly after setting the unique identifier column (see 15134_new.mp4). Should I close this ticket?

Confirmed here too with even nastier behaviour following that you use the select at id option, or that you cast geometry column to MultiPolygon.
Something is messing with feature id's somewhere.
Attribute table shows ERROR values for the multipolygon object.
