Access ESRI .GDB in PyQGIS

Question

I can access ESRI .GDB data using OSGeo's OGR. The following code gives feature class names embedded in .GDB...

from osgeo import ogr

driver = ogr.GetDriverByName("FileGDB")
data = driver.Open(r"D:\pycharm_development\turkiye_db.gdb", 0)

feature_class_list = []

for i in data:
    foo = i.GetName()
    feature_class_list.append(foo)
    feature_class_list.sort()

print feature_class_list

But I cannot access ESRI .GDB data in PyQGIS environment, unfortunately. PyQGIS works properly in my PC and .SHP files can be loaded successfully...

Is QgsVectorLayer() approach true or should QgsDataSourceURI() class be used to handle that?

P.S. I installed from OSGeo4W 64-bit installer. I'm using PyCharm IDE.

Answer 1

QgsVectorLayer() approach is true. Here is the code which can read field names of a specific feature class in ESRI .GDB:

from qgis.core import *

QgsApplication.setPrefixPath("D:/OSGeo4W64/apps/qgis", True)
QgsApplication.initQgis() 

layer = QgsVectorLayer("D:/pycharm/turkiye_db.gdb|layername=tr_il", "provinces", "ogr")

fields = layer.pendingFields()

for i in range(fields.count()):
    field = fields[i]
    print "Name:%s" % (field.name())
