I know this is a duplication, but I have read all the other answers on the forum and haven't gotten any solution.

This is my code:

#Import environment settings
import os, sys, string
import arcpy

#Define Environment
arcpy.env.workspace = "Database Connections/TRANSCO_OEDEVT.sde/"
#Define connections
OEDEVT_SV = "Database Connections/TRANSCO_OEDEVT.sde/"
SQLDEVGIS = "Database Connections/DEV_SQLDEVGIS.sde"

#Check to see if any tables for write operation exists already, delete them if so
if arcpy.Exists(SQLDEVGIS + "\R_TRANSCO_PIPES"):
    print "R_TRANSCO_PIPES exists, deleting now"
    arcpy.Delete_management(SQLDEVGIS + "\PUBLISH.RISK.R_TRANSCO_PIPES")

this is the error I get:

    raise e

  • Are you sure that "Database Connections\TRANSCO_OEDEVT.sde\PODSSDE.R_PIPE_SEGMENT_SV" exists and is a table file? I don't think that tool works on feature classes.

  • @Tom, Yes, it exists as a spatial_view.

  • then if it's a spatial view--as I said--it won't work with tabletotable. You need featureclasstofeatureclass.

Two things....

1) In arcpy.Exists(SQLDEVGIS + "\R_TRANSCO_PIPES") the string "\R..." needs to be prefaced with an 'r' to denote that it is a raw string. For example, should be: arcpy.Exists(SQLDEVGIS + r"\R_TRANSCO_PIPES")

2) In this environment the _SV denotes a spatial view. If you are trying to copy featureclasses then use FeatureClassToFeatureClass_conversion

  • I added the preface 'r', but it is still giving me the same error. Could it be that I am doing something wrong?

  • Change from in_memory to the file system as a test. All Transco pipe segments would be quite large in an in_memory workspace. Could trim attributes off if this destination is necessary. Also check memory as the process is occurring as another test. I believe TableToTable is not the right tool anyway and should be FeatureClassToFeatureClass.
