I have 5 point feature classes that I am trying to append into a point feature class. I get the following error when I attempt to run the code shown below:
Failed to execute. Parameters are not valid.
ERROR 000338: Inputs must be either all Feature Classes, Tables or Rasters; not mixed.
Failed to execute (Append).
I can run the append successfully when using the Append tool in Desktop. I am at a loss as to why the code throws the error. Any insight would be very much appreciated.
# Import arcpy module
SDE = r'C:\Development\py1\gis@GISDEV02 frt (emadb51 DC) - VegD2.sde'
# Set local variables
FC_Inven = os.path.join(SDE, 'GIS.VegD_Inventory')
FC_Unit = os.path.join(SDE, 'GIS.VegD_Unit_Inventory')
FC_Hrly2 = os.path.join(SDE, 'GIS.VegD_Hourly_Inventory')
FC_Hrly = os.path.join(SDE, 'GIS.VegD_Hourly')
FC_Flat = os.path.join(SDE, 'GIS.VegD_FlatRate')
FC_Matrix = os.path.join(SDE, 'GIS.VegD_Matrix')
schemaType = "NO_TEST"
fieldMappings = ""
subtype = ""
# Process: Truncate Table
# Process: Append the feature classes into the empty feature class
arcpy.Append_management('FC_Unit; FC_Hrly2; FC_Hrly; FC_Flat; FC_Matrix', FC_Inven, schemaType, fieldMappings, subtype)
except Exception as err:
Solved! Go to Solution.
The error was caused by the Append input being interpreted as a string as opposed to variables. Below is syntax that worked for me. Thanks to all for your assistance with my issue!
arcpy.Append_management('"' + FC_Unit + ';' + FC_Hrly2 + ';' + FC_Hrly + ';' + FC_Flat + ';' + FC_Matrix + '"', FC_Inven, schemaType, fieldMappings, subtype)
have you tried a comma delimited list as inputs rather than a semi-colon delimited string?
The help isn't clear as to what is acceptable
Ah, sorry, forgot to wrap them in a list.
arcpy.Append_management( ','.join([FC_Unit, FC_Hrly2, FC_Hrly, FC_Flat, FC_Matrix]), FC_Inven, schemaType, fieldMappings, subtype)
I get the same error. I am going to copy the 6 feature classes into a fgdb and run the script on it to see if the error persists. Thanks for taking the time to offer some assistance.
Same error? Did you re-copy and paste my code? The square brackets I added to the code should have made the join error go away. There still may be an error, I am just surprised you are getting a join error still.
Sorry for my lack of clarity. The "same error" I was referring to is based on my original post. Your revision did address the argument message when I attempted to run your initial line of code.
