Hello QGis Users,
in my QGIS Plugin I am filtering layers with this Python code:
LegInt = iface.legendInterface()
layers = LegInt.layers()
TestLayer=None
for layer in layers:
layerType = layer.type()
if layer.name() == "my_layer_name":
s_lay=layer
break
FeatureIterator = layer.getFeatures(
QgsFeatureRequest().setFilterExpression ("Fieldname='SomeValue'") )
for feature in FeatureIterator :
attrs = feature.attributes()
print "Feature ID: " + str(feature.id()) + " " + str(attrs)
This works for most layer-types (shapefile, Postgis, personal GDB,etc). But
when I tried it with MSSQL Spatial layers, no results are returned. The
iterator is empty.
It works if I use the same filter clause (Fieldname='SomeValue') as a
Feature subset at Layer-Properties. Then the layer shows only the intended
subset.
I work with QGIS 2.2 and 2.4. MSSQL Server is 2008R2. My testdata was
exactly the same in Postgis and MSSQL, so I know that the filterexpression
is correct.
Could this be a bug?
Can somebody reproduce this?
Have a nice day,
Stefan
