If you want to list and write to a txt-File all featureClasses (in a FetaureDataset) stored in SDE/Oracle, it is done with a few line Python.
import arcpy from arcpy import env import os # Set the workspace for the ListFeatureClass function # env.workspace = "Database Connections/VECTOR.arcsde01.sde/FEATURE_DATASET" # Use the ListFeatureClasses function to return a list of # all shapefiles. # fcList = arcpy.ListFeatureClasses() print str(fcList) # setting up output-file and write to file file = open("sdelayers.txt", "w") file.write(str(fcList)) file.close()
