QGIS » QGIS Application

It would be handy to be able to do executeQuery which would just pass the query to the provider and return a iterator of features.

Would allow for something like this:

provider = layer.dataProvider()
features = provider.executeQuery("Select * FROM blah WHERE A = 100")
for f in features:
   ... 

This would be handy to allow to more advanced queries against a provider and letting QGIS handle all the QgsFeature creation.
