Hello,
I am trying to iterate over a non geographic table under PyQGis. The
table is stored in an Oracle database and I use QGis Api to get the data
(table is opened in a QGis project with Oracle provider). I have added
primary key constraint to this table but I am not able to iterate
through its features with the getFeatures() method. The following
snippet always returns nothing:
layer =
QgsMapLayerRegistry.instance().mapLayersByName('MY_ATTRIBUTE_TABLE')[0]
for f in layer.getFeatures():
print f
I have tried with a geographic layer and there is no problem on this
side because the above snippets prints a line for every feature in the
table. I have also tried with opening the geographic table without
geometry (geometry is "No Geometry"). In this configuration, I am not
able to get access to the features...
I have tried to reproduce this on a PostgreSQL/PostGIS server and there
is no bug: I am able to iterate over a non-geographic layer (even a
geographic layer declared as non-geographic).
Is this a problem with the Oracle provider or just me having forgotten
something in the table ?
Best regards
