I need to select just a field from a dataset to compose a model in QGIS 3.4 modeler. How could I extract this field from the main dataset while creating another one?.
I've tried with
Drop field(s) but the dataset is to large to enumerate everyfield and make the task efficient.
I also tried
Extract by attribute but it returns a blank attribute table with every field from the main dataset but no features.
The output should be similar to a pandas data selection like this:
import pandas as pd df = pd.read_csv(file_path) df_select = pd.DataFrame(df['field_name'])
